本發明係關於一種網路裝置、核心網路、直接模式通訊系統及其合法監聽方法。更具體而言，該網路裝置、核心網路、直接模式通訊系統及其合法監聽方法被配置成用於監聽在直接模式通訊中所使用之各行動台間之通訊。The present invention relates to a network device, a core network, a direct mode communication system, and a lawful interception method thereof. More specifically, the network device, core network, direct mode communication system, and its lawful interception method are configured to listen for communication between mobile stations used in direct mode communication.
出於安全原因，會需要合法通訊監聽技術。在一般通訊系統中，行動台直接連接至後端網路，且必須經由後端網路彼此交換資料(語音資料、文字資料等)。換言之，在各行動台之間所交換之資料必須藉由後端工作來處理。因此，當法院授權進行一監聽時，一被授權使用者需要向後端網路運營商請求獲得在各行動台之間交換並儲存於後端網路中之資料。For security reasons, legitimate communication monitoring techniques are required. In a general communication system, the mobile station is directly connected to the back-end network, and data (voice data, text data, etc.) must be exchanged with each other via the back-end network. In other words, the information exchanged between the various mobile stations must be handled by back-end work. Therefore, when the court authorizes a listener, an authorized userThe back-end network operator needs to be requested to obtain information exchanged between the mobile stations and stored in the back-end network.
然而，在正開發之3GPP直接模式通訊網路中，雖然行動台仍連接至後端網路，但其彼此直接交換資料。換言之，在3GPP直接模式通訊網路中，在各行動台之間進行之資料交換將不由後端網路來處理。因此，一被授權使用者無法自後端網路獲得在各行動台之間所交換之資料，乃因該資料可能並不儲存於後端網路中。However, in the 3GPP direct mode communication network being developed, although the mobile stations are still connected to the backend network, they exchange data directly with each other. In other words, in the 3GPP direct mode communication network, the data exchange between the mobile stations will not be handled by the backend network. Therefore, an authorized user cannot obtain the information exchanged between the mobile stations from the back-end network because the data may not be stored in the back-end network.
因此，為針對3GPP直接模式通訊網路實施合法監聽，需要與一般通訊系統不同之相應協定及硬體裝置。Therefore, in order to implement lawful interception for the 3GPP direct mode communication network, a corresponding agreement and hardware device different from the general communication system are required.

However, the present examples are not intended to limit the invention to any specific examples, embodiments, environments, applications or specific embodiments described in the exemplary embodiments. Accordingly, the description of the exemplary embodiments is intended to be illustrative and not restrictive. It is to be understood that in the following exemplary embodiments and the accompanying drawings, elements that are not related to the present invention will be omitted.
參照第1A圖至第1C圖。第1A圖係為本發明一第一實施例之一直接模式通訊系統1之示意圖。直接模式通訊系統1包含一網路裝置11及一核心網路13，核心網路13連接至一第一行動台15a及一第二行動台15b。第1B圖係為本發明第一實施例之網路裝置11之示意圖。網路裝置11包含一收發器111及一處理器113。第1C圖係為本發明第一實施例之核心網路13之示意圖。核心網路13包含一註冊單元131、一傳輸單元133及一儲存單元135。Refer to Figures 1A through 1C. 1A is a schematic diagram of a direct mode communication system 1 according to a first embodiment of the present invention. The direct mode communication system 1 includes a network device 11 and a core network 13, and the core network 13 is connected to a first mobile station 15a and a second mobile station 15b. FIG. 1B is a schematic diagram of the network device 11 of the first embodiment of the present invention. The network device 11 includes a transceiver 111 and a processor 113. 1C is a schematic diagram of the core network 13 of the first embodiment of the present invention. The core network 13 includes a registration unit 131, a transmission unit 133, and a storage unit 135.
應首先瞭解，本發明之核心網路可係為一後端運營網路，其由具有不同功能之不同硬體伺服器(例如具有註冊功能之一伺服器、具有傳送功能之一伺服器、具有儲存功能之一伺服器、或具有處理功能之一伺服器)構成。然而，此並非旨在限制本發明之實施方案。下文中將更闡明各網路組件間之交互作用。It should be first understood that the core network of the present invention may be a back-end operating network, which is composed of different hardware servers having different functions (for example, one server having a registration function, one server having a transmission function, and having One of the storage functions, or one of the processing functions. However, this is not intended to limit the embodiments of the invention. The interaction between the various network components will be more clarified below.
首先，當出於某些安全原因而需要監視第一行動台15a與第二行動台15b間之通訊時，一合法使用者(例如，執法人員)可請求法院授權來進行合法監聽。接下來，在被授權之後，使用者可藉由網路裝置11以後續步驟來起始合法監聽。First, when there is a need to monitor communication between the first mobile station 15a and the second mobile station 15b for some security reasons, a legitimate user (e.g., law enforcement officer) may request authorization from the court for lawful interception. Next, after being authorized, the user can use the network device 11Follow the next steps to initiate legal listening.
具體而言，為告知核心網路13欲加入直接模式通訊，網路裝置11之處理器113經由收發器111向核心網路13註冊成欲監聽第一行動台15a與第二行動台15b間之一通訊150。換言之，網路裝置11通知核心網路13欲進行監聽。因此，註冊單元131被告知並將網路裝置11註冊成欲監聽通訊150。Specifically, to inform the core network 13 that the direct mode communication is to be added, the processor 113 of the network device 11 registers with the core network 13 via the transceiver 111 to listen to the first mobile station 15a and the second mobile station 15b. A communication 150. In other words, the network device 11 notifies the core network 13 that it wants to listen. Therefore, the registration unit 131 is informed and registers the network device 11 to listen to the communication 150.
在網路裝置11註冊成欲加入直接模式通訊系統1之後，網路裝置11之收發器113開始藉由監聽通訊150而擷取一通訊資料152。因此，網路裝置11可相應地獲得並監視在第一行動台15a與第二行動台15b之間所交換之資訊。After the network device 11 registers to join the direct mode communication system 1, the transceiver 113 of the network device 11 begins to retrieve a communication material 152 by listening to the communication 150. Therefore, the network device 11 can accordingly obtain and monitor the information exchanged between the first mobile station 15a and the second mobile station 15b.
然後，網路裝置11之處理器113經由收發器111將通訊資料152儲存於核心網路13中(或若網路裝置11具有足夠儲存空間，則臨時儲存於網路裝置11自身中)，以供隨後使用。換言之，核心網路13之傳輸單元133自網路裝置11接收通訊資料152，且核心網路13之儲存單元135儲存通訊資料152以供隨後使用。因此，基於本發明之第一實施例，可在直接模式通訊系統1中實施合法監聽。Then, the processor 113 of the network device 11 stores the communication data 152 in the core network 13 via the transceiver 111 (or temporarily stored in the network device 11 itself if the network device 11 has sufficient storage space). For subsequent use. In other words, the transmission unit 133 of the core network 13 receives the communication material 152 from the network device 11, and the storage unit 135 of the core network 13 stores the communication material 152 for subsequent use. Therefore, based on the first embodiment of the present invention, lawful interception can be implemented in the direct mode communication system 1.
參照第2圖，其顯示例示本發明一第二實施例之一直接模式通訊系統2之示意圖。應尤其瞭解，第二實施例具有與第一實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。Referring to Fig. 2, there is shown a schematic diagram illustrating a direct mode communication system 2 of a second embodiment of the present invention. It should be particularly appreciated that the second embodiment has the same system architecture and the same network connection environment as the first embodiment, and therefore components having the same reference numerals have the same functions and will not be further described herein.
具體而言，網路裝置11同時處於第一行動台15a之一第一通訊覆蓋範圍154及第二行動台15b之一第二通訊覆蓋範圍156內。因此，網路裝置11之收發器111同時連接至第一行動台15a及第二行動台15b，並藉由直接自第一行動台15a及第二行動台15b二者監聽通訊150而接收通訊資料152。Specifically, the network device 11 is simultaneously in the first communication coverage 154 of one of the first mobile stations 15a and the second communication coverage 156 of one of the second mobile stations 15b. Therefore, the netThe transceiver 111 of the road device 11 is simultaneously connected to the first mobile station 15a and the second mobile station 15b, and receives the communication material 152 by directly listening to the communication 150 from both the first mobile station 15a and the second mobile station 15b.
然而，應注意，若網路裝置11不處於第一行動台15a之第一通訊覆蓋範圍154或第二行動台15b之第二通訊覆蓋範圍156內，則應調整第一行動台15a及第二行動台15b之通訊功率。However, it should be noted that if the network device 11 is not within the first communication coverage 154 of the first mobile station 15a or the second communication coverage 156 of the second mobile station 15b, the first mobile station 15a and the second should be adjusted.

請參照第3A圖及第3B圖。第3A圖係為本發明一第三實施例之一直接模式通訊系統3之示意圖，且第3B圖係為本發明第三實施例之一核心網路13’之示意圖。應尤其注意，第三實施例之硬體結構及網路連接環境類似於第二實施例之硬體結構及網路連接環境，因此具有相同參考編號之組件具有相同之功能且將不在本文中更加以說明。第三實施例與第二實施例之不同在於，核心網路13’更包含一判斷單元137。Please refer to Figures 3A and 3B. 3A is a schematic diagram of a direct mode communication system 3 according to a third embodiment of the present invention, and FIG. 3B is a schematic diagram of a core network 13' according to a third embodiment of the present invention. It should be particularly noted that the hardware structure and the network connection environment of the third embodiment are similar to the hardware structure and the network connection environment of the second embodiment, and therefore components having the same reference number have the same functions and will not be further described herein. To illustrate. The third embodiment is different from the second embodiment in that the core network 13' further includes a judging unit 137.
具體而言，核心網路13’之判斷單元137用於判斷網路裝置11是否處於第一行動台15a及第二行動台15b之通訊覆蓋範圍154’、156’內。然後，當核心網路13’之判斷單元137判定網路裝置11不處於第一行動台15a之通訊覆蓋範圍154’或第二行動台15b之通訊覆蓋範圍156’內時，傳輸單元133更向第一行動台15a及第二行動台15b分別傳送功率調整訊號130a及130b，以私密地調整第一行動台15a及第二行動台15b之通訊功率。Specifically, the determining unit 137 of the core network 13' is for determining whether the network device 11 is in the communication coverage areas 154', 156' of the first mobile station 15a and the second mobile station 15b. Then, when the determining unit 137 of the core network 13' determines that the network device 11 is not within the communication coverage 154' of the first mobile station 15a or the communication coverage 156' of the second mobile station 15b, the transmission unit 133 is further directed The first mobile station 15a and the second mobile station 15b transmit power adjustment signals 130a and 130b, respectively, to privately adjust the communication power of the first mobile station 15a and the second mobile station 15b.
因此，網路裝置11能夠同時連接至第一行動台15a及第二行動台15b，且收發器111能夠藉由監聽第一行動台15a與第二行動台15b間之一通訊而直接自第一行動台15a及第二行動台15b接收通訊資料。Therefore, the network device 11 can be simultaneously connected to the first mobile station 15a and the second mobile station 15b, and the transceiver 111 can directly from the first by monitoring communication between the first mobile station 15a and the second mobile station 15b.

參照第4圖，其顯示例示本發明一第四實施例之一直接模式通訊系統4之示意圖。應尤其瞭解，第四實施例具有與前述實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。然而，第四實施例與前述實施例之不同在於：網路裝置11僅處於第一行動台15a之通訊覆蓋範圍154內，因此更向直接模式通訊系統4中引入一網路裝置17(包含與網路裝置11相同之組件)，以用於監聽自第二行動台15b所傳送之資料。Referring to Figure 4, there is shown a direct mode illustrating a fourth embodiment of the present invention.Schematic diagram of communication system 4. It should be particularly appreciated that the fourth embodiment has the same system architecture and the same network connection environment as the previous embodiments, and therefore components having the same reference numerals have the same functions and will not be further described herein. However, the fourth embodiment is different from the foregoing embodiment in that the network device 11 is only in the communication coverage 154 of the first mobile station 15a, so that a network device 17 is further introduced into the direct mode communication system 4 (including The network device 11 is the same component for monitoring the data transmitted from the second mobile station 15b.

Therefore, the network device 17 is introduced for connecting the second mobile station 15b and listening to the communication material 152 of the second mobile station 15b. Therefore, the monitoring data of the communication 150 is relatively complete.
此外，在其他實施例中，第一行動台15a可係為一行動台群組中之一個成員，且由於網路裝置11僅連接至第一行動台15a，因而網路裝置11可直接自第一行動台15a獲得該行動台群組之部分通訊資訊。In addition, in other embodiments, the first mobile station 15a can be a member of a mobile station group, and since the network device 11 is only connected to the first mobile station 15a, the network device 11 can directly A mobile station 15a obtains part of the communication information of the mobile station group.
亦應注意，在第四實施例中，若網路裝置11不處於第一行動台15a之第一通訊覆蓋範圍154內，或網路裝置17不處於第二行動台15b之第二通訊覆蓋範圍156內，則應如第三實施例中所述者經由額外判斷單元來調整第一行動台15a及第二行動台15b之通訊功率。因此，功率調整之細節將不在本文中更加以說明。It should also be noted that in the fourth embodiment, if the network device 11 is not in the first communication coverage 154 of the first mobile station 15a, or the network device 17 is not in the second communication coverage of the second mobile station 15b. In 156, the communication power of the first mobile station 15a and the second mobile station 15b should be adjusted via an additional judging unit as described in the third embodiment. Therefore, the details of the power adjustment will not be further explained in this article.

It should be particularly appreciated that the fifth embodiment has the same system architecture and the same network connection environment as the first embodiment, and therefore components having the same reference number also have phases.The same function and will not be further explained in this article.
具體而言，在第五實施例中，網路裝置11係為一中繼台，且第一行動台15a經由網路裝置11與第二行動台15b進行通訊。因此，網路裝置11之收發器111能夠藉由在於第一行動台15a與第二行動台15b之間中繼通訊資料152之同時監聽通訊150而擷取通訊資料152。Specifically, in the fifth embodiment, the network device 11 is a relay station, and the first mobile station 15a communicates with the second mobile station 15b via the network device 11. Therefore, the transceiver 111 of the network device 11 can retrieve the communication material 152 by monitoring the communication 150 while relaying the communication material 152 between the first mobile station 15a and the second mobile station 15b.

參照第11A圖至第11C圖。第11A圖係為本發明一第十一實施例之一3GPP直接模式通訊系統6之示意圖。3GPP直接模式通訊系統6包含一使用者監聽設備61、一管理伺服器63及一eNB 65。一第一使用者設備67經由eNB 65與管理伺服器63連接。Refer to Figures 11A through 11C. 11A is a schematic diagram of a 3GPP direct mode communication system 6 according to an eleventh embodiment of the present invention. The 3GPP direct mode communication system 6 includes a user listening device 61, a management server 63, and an eNB 65. A first user device 67 is connected to the management server 63 via the eNB 65.
第11B圖係為本發明第十一實施例之使用者監聽設備61之示意圖。使用者監聽設備61包含一收發器611及一處理器613。第11C圖係為本發明第十一實施例之管理伺服器63之示意圖。管理伺服器63包含一收發器631及一處理器633。Figure 11B is a schematic diagram of the user listening device 61 of the eleventh embodiment of the present invention. The user monitoring device 61 includes a transceiver 611 and a processor 613. Figure 11C is a schematic diagram of the management server 63 of the eleventh embodiment of the present invention. The management server 63 includes a transceiver 631 and a processor 633.
應首先瞭解，本發明之管理伺服器可係為一後端運營伺服器，其具有不同功能，例如註冊功能、傳送功能、儲存功能、定位功能(例如，3GPP網路中基於近接性之服務功能)、及管理功能(例如，3GPP網路中之管理功能)。然而，此並非旨在限制本發明之實施方案。下文中將更闡明各網路組件間之交互作用。It should be first understood that the management server of the present invention can be a back-end operation server having different functions such as registration function, transmission function, storage function, and positioning function (for example, proximity-based service function in 3GPP network) ), and management functions (for example, management functions in the 3GPP network). However, this is not intended to limit the embodiments of the invention. The interaction between the various network components will be more clarified below.
具體而言，當出於某些安全原因而需要監視第一使用者設備67之通訊時，一合法使用者(例如，執法人員)可請求法院授權來進行合法監聽。接下來，在被授權之後，可如下來達成合法監聽。In particular, when it is desired to monitor the communication of the first user device 67 for some security reasons, a legitimate user (eg, a law enforcement officer) may request authorization from the court for lawful interception. Next, after being authorized, legal interception can be achieved as follows.
首先，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65向管理伺服器63註冊成欲進行合法監聽。然後，若使用者監聽設備61係為合法的，則管理伺服器63之處理器633藉由收發器631授權使用者監聽設備61來執行合法監聽。在註冊成欲加入3GPP直接模式通訊系統6之後，使用者監聽設備61便準備好進行合法監聽。First, the processor 613 of the user monitoring device 61 registers with the management server 63 via the transceiver 611 via the eNB 65 to perform lawful interception. Then, if the user listening device 61 is legitimate, the processor 633 of the management server 63 authorizes the user to listen to the device 61 by the transceiver 631 to perform lawful interception. Registered to join the 3GPP direct mode communication system 6After that, the user monitoring device 61 is ready for lawful interception.
在第十一實施例中，當需要監視具有一第一辨識碼ID1之第一使用者設備67時，管理伺服器63自複數個合法使用者監聽設備(圖中未顯示)中確定一合法使用者設備來用於監聽第一使用者設備67。由於管理伺服器63具有用於定位使用者設備之ProSe功能，因而管理伺服器63能夠確定較靠近第一使用者設備67之一使用者設備(在第十一實施例中，其係為使用者監聽設備61)來用於監聽第一使用者設備67。In the eleventh embodiment, when it is required to monitor the first user device 67 having a first identification code ID1, the management server 63 determines a legal use from a plurality of legitimate user listening devices (not shown). The device is used to listen to the first user device 67. Since the management server 63 has a ProSe function for locating the user device, the management server 63 can determine that the user device is closer to the first user device 67 (in the eleventh embodiment, it is a user) The listening device 61) is used to listen to the first user device 67.
接下來，管理伺服器63之處理器633藉由經由收發器631、經由eNB 65向使用者監聽設備61傳送一肯定監聽訊息630來起始監聽，其中肯定監聽訊息630包含第一使用者設備67之第一辨識碼ID1。換言之，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65自管理伺服器63接收肯定監聽訊息630。Next, the processor 633 of the management server 63 initiates the monitoring by transmitting a positive listening message 630 to the user listening device 61 via the transceiver 631 via the eNB 65, wherein the positive listening message 630 includes the first user device 67. The first identification code ID1. In other words, the processor 613 of the user listening device 61 receives the positive listening message 630 from the management server 63 via the eNB 65 via the transceiver 611.
由於使用者監聽設備61被通知應監聽第一使用者設備67，因而使用者監聽設備61試圖達及第一使用者設備67。更具體而言，在第十一實施例中，使用者監聽設備61之處理器613基於第一辨識碼ID1而藉由收發器611自第一使用者設備67接收一第一訊號670。第一訊號可包含控制平面訊號(control plane signal)及/或使用者平面訊號(user plane signal)，其中控制平面訊號可係為同步訊號或參考訊號，且使用者平面訊號係為在專用及/或共用資源區塊上傳送之一資料。Since the user listening device 61 is notified that the first user device 67 should be monitored, the user listening device 61 attempts to reach the first user device 67. More specifically, in the eleventh embodiment, the processor 613 of the user monitoring device 61 receives a first signal 670 from the first user device 67 via the transceiver 611 based on the first identification code ID1. The first signal may include a control plane signal and/or a user plane signal, wherein the control plane signal may be a synchronous signal or a reference signal, and the user plane signal is dedicated and/or Or transfer one of the materials on the shared resource block.
然後，使用者監聽設備61之處理器613判斷第一訊號670之一第一功率量測值P1是否超過一臨限值(圖中未顯示)。功率量測值可係為訊號對干擾加雜訊比(Signal to Interference plus Noise Ratio；SINR)、接收訊號強度指示符(Received Signal Strength Indicator；RSSI)、參考訊號接收功率(Reference Signal Received Power；RSRP)、或參考訊號接收品質(Reference Signal Received Quality；RSRQ)等。若第一訊號670之第一功率量測值P1超過臨限值，則此意味著，使用者監聽設備61能夠自第一使用者設備67正確地接收通訊資料DATA1。因此，使用者監聽設備61可基於第一辨識碼ID1而直接接收第一使用者設備67之通訊資料DATA1。Then, the processor 613 of the user monitoring device 61 determines whether the first power measurement value P1 of the first signal 670 exceeds a threshold (not shown). The power measurement value can be connected to the signal to interference plus noise ratio (SINR).Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), or Reference Signal Received Quality (RSRQ). If the first power measurement value P1 of the first signal 670 exceeds the threshold value, this means that the user monitoring device 61 can correctly receive the communication data DATA1 from the first user equipment 67. Therefore, the user monitoring device 61 can directly receive the communication data DATA1 of the first user device 67 based on the first identification code ID1.
另一方面，若第一訊號670之第一功率量測值P1不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67正確地接收通訊資料DATA1，乃因自第一使用者設備67所接收之功率並不好至足以使第一使用者設備67達及使用者監聽設備61。因此，應提高第一使用者設備67之傳送功率。On the other hand, if the first power measurement value P1 of the first signal 670 does not exceed the threshold value, this means that the user monitoring device 61 may not correctly receive the communication data DATA1 from the first user equipment 67. The power received from the first user device 67 is not good enough for the first user device 67 to reach the user listening device 61. Therefore, the transmission power of the first user equipment 67 should be increased.
因此，使用者監聽設備61之處理器613基於第一功率量測值P1不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送一功率調整請求610，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送一功率調整命令650，以調整第一使用者設備67之傳送功率。隨後，在第十一實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits a power adjustment request 610 to the management server 63 via the transceiver 611 via the eNB 65 based on the determination that the first power measurement value P1 does not exceed the threshold value, so that the power adjustment request 610 is transmitted to the management server 63 via the eNB 65. The management server 63 notifies the eNB 65 that a power adjustment command 650 should be transmitted to the first user equipment 67 to adjust the transmission power of the first user equipment 67. Subsequently, in the eleventh embodiment, the processor 613 of the user listening device 61 can correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
應注意，在第十一實施例中，若連續地判定自第一使用者設備67所接收之功率不超過臨限值，則重複上述功率調整方案，直至自第一使用者設備67所接收之功率超過臨限值為止。It should be noted that, in the eleventh embodiment, if it is continuously determined that the power received from the first user equipment 67 does not exceed the threshold, the power adjustment scheme is repeated until it is received from the first user equipment 67. The power exceeds the threshold.
參照第12圖，其顯示例示本發明一第十二實施例之一3GPP直接模式通訊系統7之示意圖。應尤其瞭解，第十二實施例具有與第十一實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。第十二實施例與第十一實施例之不同在於，不僅可使用訊號之功率量測值而且可使用通訊資料之功率量測值來與臨限值進行比較。Referring to Figure 12, there is shown a 3GPP of a twelfth embodiment of the present invention.Schematic diagram of the direct mode communication system 7. It is to be understood that the twelfth embodiment has the same system architecture and the same network connection environment as the eleventh embodiment, and therefore components having the same reference numerals have the same functions and will not be further described herein. The twelfth embodiment differs from the eleventh embodiment in that not only the power measurement value of the signal but also the power measurement value of the communication data can be used to compare with the threshold value.
具體而言，在不同實施方案中，在監聽通訊資料DATA1之後，使用者監聽設備61之處理器613更判斷自第一使用者設備67所接收之功率是否超過臨限值。在一個實施方案中，使用者監聽設備61之處理器613更基於第一辨識碼ID1而藉由收發器611自第一使用者設備67接收一第二訊號672。Specifically, in various embodiments, after listening to the communication data DATA1, the processor 613 of the user monitoring device 61 further determines whether the power received from the first user device 67 exceeds a threshold. In one embodiment, the processor 613 of the user monitoring device 61 receives a second signal 672 from the first user device 67 via the transceiver 611 based on the first identification code ID1.
然後，使用者監聽設備61之處理器613更判斷第二訊號672之一第二功率量測值P2是否超過臨限值。若第二訊號672之第二功率量測值P2超過臨限值，則此意味著，使用者監聽設備61能夠自第一使用者設備67連續且正確地監聽通訊資料DATA1。Then, the processor 613 of the user monitoring device 61 further determines whether the second power measurement value P2 of the second signal 672 exceeds the threshold. If the second power measurement value P2 of the second signal 672 exceeds the threshold value, this means that the user monitoring device 61 can continuously and correctly monitor the communication data DATA1 from the first user equipment 67.
另一方面，若第二訊號672之第二功率量測值P2不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67正確地接收通訊資料DATA1，乃因自第一使用者設備67所接收之功率仍不足夠好。因此，應提高第一使用者設備67之傳送功率。On the other hand, if the second power measurement value P2 of the second signal 672 does not exceed the threshold value, this means that the user monitoring device 61 may not correctly receive the communication data DATA1 from the first user equipment 67. The power received from the first user device 67 is still not good enough. Therefore, the transmission power of the first user equipment 67 should be increased.
因此，使用者監聽設備61之處理器613基於第二功率量測值P2不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送另一功率調整請求612，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送另一功率調整命令652，以調整第一使用者設備67之傳送功率。隨後，在第十二實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67連續且正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits another power adjustment request 612 to the management server 63 via the transceiver 611 via the eNB 65 based on the determination that the second power measurement value P2 does not exceed the threshold value. The management server 63 is informed that the eNB 65 should transmit another power adjustment command 652 to the first user equipment 67 to adjust the transmission power of the first user equipment 67.rate. Subsequently, in the twelfth embodiment, the processor 613 of the user listening device 61 can continuously and correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
在另一實施方案中，使用者監聽設備61之處理器613直接判斷通訊資料DATA1之一功率量測值P3是否超過臨限值。若通訊資料DATA1之功率量測值P3超過臨限值，則此意味著，使用者監聽設備61會自第一使用者設備67連續且正確地接收通訊資料DATA1。因此，使用者監聽設備61繼續基於第一辨識碼ID1而監聽第一使用者設備67之通訊資料DATA1。In another embodiment, the processor 613 of the user monitoring device 61 directly determines whether the power measurement value P3 of one of the communication data DATA1 exceeds a threshold. If the power measurement value P3 of the communication data DATA1 exceeds the threshold value, this means that the user monitoring device 61 continuously and correctly receives the communication data DATA1 from the first user equipment 67. Therefore, the user monitoring device 61 continues to monitor the communication material DATA1 of the first user device 67 based on the first identification code ID1.
另一方面，若通訊資料DATA1之功率量測值P3不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67連續且正確地接收通訊資料DATA1，乃因自第一使用者設備67所接收之功率仍不足夠好。因此，應再次提高第一使用者設備67之傳送功率。On the other hand, if the power measurement value P3 of the communication data DATA1 does not exceed the threshold value, this means that the user monitoring device 61 may not continuously and correctly receive the communication data DATA1 from the first user equipment 67. The power received from the first user device 67 is still not good enough. Therefore, the transmission power of the first user equipment 67 should be increased again.
因此，使用者監聽設備61之處理器613基於功率量測值P3不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送另一功率調整請求614，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送另一功率調整命令654，以調整第一使用者設備67之傳送功率。隨後，在第十二實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67連續且正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits another power adjustment request 614 to the management server 63 via the transceiver 611 via the eNB 65 based on the determination that the power measurement value P3 does not exceed the threshold value, so as to enable management. The server 63 informs the eNB 65 that another power adjustment command 654 should be transmitted to the first user equipment 67 to adjust the transmit power of the first user equipment 67. Subsequently, in the twelfth embodiment, the processor 613 of the user listening device 61 can continuously and correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
參照第13圖，其顯示例示本發明一第十三實施例之一3GPP直接模式通訊系統8之示意圖。應尤其瞭解，第十三實施例具有與第十一實施例或第十二實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。第十三實施例與上述實施例之不同在於，可由使用者監聽設備來起始合法監聽。Referring to Fig. 13, there is shown a schematic diagram illustrating a 3GPP direct mode communication system 8 of a thirteenth embodiment of the present invention. It should be particularly appreciated that the thirteenth embodiment has the same system architecture and the same network connection environment as the eleventh embodiment or the twelfth embodiment, and thus hasComponents of the same reference number also have the same function and will not be further described herein. The thirteenth embodiment is different from the above embodiment in that legal listening can be initiated by the user listening device.
類似地，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65向管理伺服器63註冊成欲進行合法監聽。然後，若使用者監聽設備61係為合法的，則管理伺服器63之處理器633藉由收發器631授權使用者監聽設備61來執行合法監聽。在註冊成欲加入3GPP直接模式通訊系統8之後，使用者監聽設備61便準備好進行合法監聽。Similarly, the processor 613 of the user listening device 61 registers with the management server 63 via the eNB 65 via the transceiver 611 to perform lawful interception. Then, if the user listening device 61 is legitimate, the processor 633 of the management server 63 authorizes the user to listen to the device 61 by the transceiver 631 to perform lawful interception. After registering to join the 3GPP direct mode communication system 8, the user listening device 61 is ready for lawful interception.
在第十三實施例中，當使用者監聽設備61需要監視一附近之使用者時，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65向管理伺服器63傳送一監聽請求訊息616，且監聽請求訊息616包含關於使用者之使用者資料(圖中未顯示)，例如使用者之名稱、使用者之電話號碼等。隨後，管理伺服器63能夠基於使用者資料而辨識第一使用者設備67。In the thirteenth embodiment, when the user listening device 61 needs to monitor a nearby user, the processor 613 of the user listening device 61 transmits a listening request to the management server 63 via the transceiver 611 via the eNB 65. Message 616, and the listen request message 616 contains user data about the user (not shown), such as the name of the user, the phone number of the user, and the like. Subsequently, the management server 63 can recognize the first user device 67 based on the user profile.
因此，管理伺服器63之處理器633藉由收發器631、經由eNB 65向使用者監聽設備61傳送肯定監聽訊息630，其中肯定監聽訊息630包含第一使用者設備67之第一辨識碼ID1。換言之，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65自管理伺服器63接收肯定監聽訊息630。Therefore, the processor 633 of the management server 63 transmits a positive listening message 630 to the user monitoring device 61 via the eNB 65 via the transceiver 631, wherein the positive listening message 630 includes the first identification code ID1 of the first user device 67. In other words, the processor 613 of the user listening device 61 receives the positive listening message 630 from the management server 63 via the eNB 65 via the transceiver 611.
接下來，使用者監聽設備61試圖基於第一辨識碼ID1而達及第一使用者設備67。類似地，在第十三實施例中，使用者監聽設備61之處理器613基於第一辨識碼ID1而藉由收發器611自第一使用者設備67接收第一訊號670。Next, the user listening device 61 attempts to reach the first user device 67 based on the first identification code ID1. Similarly, in the thirteenth embodiment, the processor 613 of the user listening device 61 receives the first user device 67 by the transceiver 611 based on the first identification code ID1.The first signal 670.
然後，使用者監聽設備61之處理器613判斷第一訊號670之第一功率量測值P1是否超過臨限值。若第一訊號670之第一功率量測值P1超過臨限值，則此意味著，使用者監聽設備61能夠自第一使用者設備67正確地接收通訊資料DATA1。因此，使用者監聽設備61可基於第一辨識碼ID1而直接監聽第一使用者設備67之通訊資料DATA1。Then, the processor 613 of the user monitoring device 61 determines whether the first power measurement value P1 of the first signal 670 exceeds the threshold. If the first power measurement value P1 of the first signal 670 exceeds the threshold value, this means that the user monitoring device 61 can correctly receive the communication data DATA1 from the first user equipment 67. Therefore, the user monitoring device 61 can directly monitor the communication data DATA1 of the first user device 67 based on the first identification code ID1.
另一方面，若第一訊號670之第一功率量測值P1不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67正確地接收通訊資料DATA1，乃因自第一使用者設備67所接收之功率並不好至足以達及使用者監聽設備61。因此，應提高第一使用者設備67之傳送功率。On the other hand, if the first power measurement value P1 of the first signal 670 does not exceed the threshold value, this means that the user monitoring device 61 may not correctly receive the communication data DATA1 from the first user equipment 67. The power received from the first user device 67 is not good enough to reach the user listening device 61. Therefore, the transmission power of the first user equipment 67 should be increased.
因此，使用者監聽設備61之處理器613基於第一功率量測值P1不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送功率調整請求610，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送功率調整命令650，以調整第一使用者設備67之傳送功率。隨後，在第十三實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits the power adjustment request 610 to the management server 63 via the eNB 65 based on the determination that the first power measurement value P1 does not exceed the threshold value, and causes the management to be managed. The server 63 notifies the eNB 65 that the power adjustment command 650 should be transmitted to the first user equipment 67 to adjust the transmission power of the first user equipment 67. Subsequently, in the thirteenth embodiment, the processor 613 of the user listening device 61 can correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
參照第14圖，其顯示例示本發明一第十四實施例之一3GPP直接模式通訊系統6’之示意圖。應尤其瞭解，第十四實施例具有與第十一實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。第十四實施例與第十一實施例之不同在於，存在又一個欲被監聽之使用者設備。Referring to Fig. 14, there is shown a schematic diagram illustrating a 3GPP direct mode communication system 6' according to a fourteenth embodiment of the present invention. It is to be understood that the fourteenth embodiment has the same system architecture and the same network connection environment as the eleventh embodiment, and therefore components having the same reference numerals have the same functions and will not be further described herein. The fourteenth embodiment differs from the eleventh embodiment in that there is another user device to be monitored.
在第十四實施例中，當需要監視具有第一辨識碼ID1之第一使用者設備67與具有一第二辨識碼ID2之一第二使用者設備69間之一直接通訊時，管理伺服器63之處理器633自複數個合法使用者監聽設備中確定一合法使用者設備來用於監聽第一使用者設備67及第二使用者設備69。In the fourteenth embodiment, when it is necessary to monitor direct communication between the first user equipment 67 having the first identification code ID1 and the second user equipment 69 having one of the second identification codes ID2, the management server The processor 633 of 63 determines a legitimate user device from a plurality of legitimate user listening devices for monitoring the first user device 67 and the second user device 69.
類似地，由於管理伺服器63具有用於定位使用者設備之ProSe功能，因而管理伺服器63能夠確定最靠近第一使用者設備67及第二使用者設備69之一使用者設備(在第十四實施例中，其係為使用者監聽設備61)來用於監聽第一使用者設備67與第二使用者設備69間之直接通訊。Similarly, since the management server 63 has a ProSe function for locating the user device, the management server 63 can determine the user device closest to the first user device 67 and the second user device 69 (at the tenth In the fourth embodiment, it is a user listening device 61) for monitoring direct communication between the first user device 67 and the second user device 69.
接下來，管理伺服器63之處理器633藉由經由收發器631、經由eNB 65向使用者監聽設備61傳送一肯定監聽訊息630’來起始監聽，其中肯定監聽訊息630’包含第一使用者設備67之第一辨識碼ID1及第二使用者設備69之第二辨識碼ID2。換言之，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65自管理伺服器63接收肯定監聽訊息630’。Next, the processor 633 of the management server 63 initiates the monitoring by transmitting a positive listening message 630' to the user listening device 61 via the transceiver 631 via the eNB 65, wherein the positive listening message 630' includes the first user. The first identification code ID1 of the device 67 and the second identification code ID2 of the second user device 69. In other words, the processor 613 of the user listening device 61 receives the positive listening message 630' from the management server 63 via the eNB 65 via the transceiver 611.
由於使用者監聽設備61被通知應監聽第一使用者設備67與第二使用者設備69間之直接通訊，因而使用者監聽設備61試圖達及第一使用者設備67與第二使用者設備69二者。更具體而言，在第十四實施例中，使用者監聽設備61之處理器613基於第一辨識碼ID1及第二辨識碼ID2而藉由收發器611自第一使用者設備67接收第一訊號670並自第二使用者設備69接收一第二訊號690。Since the user monitoring device 61 is notified that the direct communication between the first user device 67 and the second user device 69 should be monitored, the user listening device 61 attempts to reach the first user device 67 and the second user device 69. both. More specifically, in the fourteenth embodiment, the processor 613 of the user monitoring device 61 receives the first from the first user device 67 by the transceiver 611 based on the first identification code ID1 and the second identification code ID2. Signal 670 receives a second signal 690 from second user device 69.
然後，使用者監聽設備61之處理器613判斷第一訊號670之第一功率量測值P1及第二訊號690之一第二功率量測值P4是否超過臨限值。若第一訊號670之第一功率量測值P1或第二訊號690之第二功率量測值P4超過臨限值，則此意味著，使用者監聽設備61能夠自第一使用者設備67或第二使用者設備69正確地接收第一使用者設備67與第二使用者設備69間之通訊資料DATA2。因此，使用者監聽設備61可基於第一辨識碼ID1或第二辨識碼ID2而直接監聽第一使用者設備67與第二使用者設備69間之通訊資料DATA2。Then, the processor 613 of the user monitoring device 61 determines whether the first power measurement value P1 of the first signal 670 and the second power measurement value P4 of the second signal 690 exceed a threshold value. If the first power measurement value P1 of the first signal 670 or the second power measurement value of the second signal 690If P4 exceeds the threshold, this means that the user monitoring device 61 can correctly receive communication between the first user device 67 and the second user device 69 from the first user device 67 or the second user device 69. Data DATA2. Therefore, the user monitoring device 61 can directly monitor the communication data DATA2 between the first user device 67 and the second user device 69 based on the first identification code ID1 or the second identification code ID2.
另一方面，若第一訊號670之第一功率量測值P1不超過臨限值且第二訊號690之第二功率量測值P4不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67及第二使用者設備69正確地接收通訊資料DATA2，乃因自第一使用者設備67及第二使用者設備69所接收之功率並不好至足以達及使用者監聽設備61。因此，應提高第一使用者設備67及第二使用者設備69之傳送功率。On the other hand, if the first power measurement value P1 of the first signal 670 does not exceed the threshold value and the second power measurement value P4 of the second signal 690 does not exceed the threshold value, this means that the user monitors the device. 61 may not correctly receive the communication data DATA2 from the first user device 67 and the second user device 69, because the power received from the first user device 67 and the second user device 69 is not good enough. And the user monitors the device 61. Therefore, the transmission power of the first user equipment 67 and the second user equipment 69 should be increased.
因此，使用者監聽設備61之處理器613基於第一功率量測值P1不超過臨限值且第二功率量測值P4不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送一功率調整請求610’，俾使管理伺服器63通知eNB 65應向第一使用者設備67及第二使用者設備69傳送一功率調整命令650’，以調整第一使用者設備67及第二使用者設備69之傳送功率。Therefore, the processor 613 of the user monitoring device 61 is based on the determination that the first power measurement value P1 does not exceed the threshold value and the second power measurement value P4 does not exceed the threshold value, and is transmitted by the transceiver 611 via the eNB 65. The management server 63 transmits a power adjustment request 610', and causes the management server 63 to notify the eNB 65 that a power adjustment command 650' should be transmitted to the first user equipment 67 and the second user equipment 69 to adjust the first user. The transmission power of the device 67 and the second user equipment 69.
隨後，在第十四實施例中，使用者監聽設備61之處理器613能夠藉由收發器611基於第一辨識碼ID1自第一使用者設備67或基於第二辨識碼ID2自第二使用者設備69正確地監聽通訊資料DATA2。Then, in the fourteenth embodiment, the processor 613 of the user monitoring device 61 can be from the second user by the transceiver 611 based on the first identification code ID1 from the first user device 67 or based on the second identification code ID2. The device 69 correctly listens to the communication data DATA2.
參照第15圖，其顯示例示本發明一第十五實施例之一3GPP直接模式通訊系統9之示意圖。應尤其瞭解，第十五實施例具有與第十一實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。第十五實施例與第十一實施例之不同在於，使用者設備係基於分組而彼此進行通訊。Referring to Fig. 15, there is shown a schematic diagram illustrating a 3GPP direct mode communication system 9 of a fifteenth embodiment of the present invention. It should be particularly appreciated that the fifteenth embodiment has the same system architecture and the same network connection environment as the eleventh embodiment, and therefore has the same reference number.Components also have the same functionality and will not be described further herein. The fifteenth embodiment differs from the eleventh embodiment in that the user equipment communicates with each other based on the grouping.
首先，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65向管理伺服器63註冊成欲進行合法監聽。在註冊成欲加入3GPP直接模式通訊系統9之後，使用者監聽設備61便準備好進行合法監聽。First, the processor 613 of the user monitoring device 61 registers with the management server 63 via the transceiver 611 via the eNB 65 to perform lawful interception. After registering to join the 3GPP direct mode communication system 9, the user listening device 61 is ready for lawful interception.
在第十五實施例中，第一使用者設備67被分組至具有一群組辨識碼GID之一使用者設備群組GP中。類似地，當需要監視具有第一辨識碼ID1之第一使用者設備67時，管理伺服器63自複數個合法使用者監聽設備中確定一合法使用者設備來用於監聽第一使用者設備67。在第十五實施例中，確定使用者監聽設備61來用於使用者監聽設備群組GP中之第一使用者設備67。In the fifteenth embodiment, the first user equipment 67 is grouped into a user equipment group GP having a group identification code GID. Similarly, when it is required to monitor the first user device 67 having the first identification code ID1, the management server 63 determines a legitimate user device from among the plurality of legitimate user listening devices for monitoring the first user device 67. . In the fifteenth embodiment, the user listening device 61 is determined for the user to listen to the first user device 67 in the device group GP.
接下來，管理伺服器63之處理器63藉由經由收發器631、經由eNB 65向使用者監聽設備61傳送一肯定監聽訊息630”來起始監聽，其中肯定監聽訊息630”包含第一使用者設備67之第一辨識碼ID1、及群組辨識碼GID。換言之，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65自管理伺服器63接收肯定監聽訊息630”。Next, the processor 63 of the management server 63 initiates the monitoring by transmitting a positive listening message 630" to the user listening device 61 via the eNB 65 via the eNB 65, wherein the positive listening message 630" includes the first user. The first identification code ID1 of the device 67 and the group identification code GID. In other words, the processor 613 of the user listening device 61 receives the positive listening message 630" from the management server 63 via the eNB 65 via the transceiver 611.
由於使用者監聽設備61被通知應使用者監聽設備群組GP之第一使用者設備67，因而使用者監聽設備61試圖達及第一使用者設備67。更具體而言，在第十五實施例中，使用者監聽設備61之處理器613基於第一辨識碼ID1及群組辨識碼GID而藉由收發器611自第一使用者設備67接收第一訊號670。Since the user listening device 61 is notified that the user should listen to the first user device 67 of the device group GP, the user listening device 61 attempts to reach the first user device 67. More specifically, in the fifteenth embodiment, the processor 613 of the user monitoring device 61 receives the first from the first user device 67 by the transceiver 611 based on the first identification code ID1 and the group identification code GID. Signal 670.
然後，使用者監聽設備61之處理器613判斷第一訊號670之第一功率量測值P1是否超過臨限值。若第一訊號670之第一功率量測值P1超過臨限值，則此意味著，使用者監聽設備61能夠自第一使用者設備67正確地接收通訊資料DATA1。因此，使用者監聽設備61可基於第一辨識碼ID1及群組辨識碼GID而直接監聽第一使用者設備67之通訊資料DATA1。Then, the processor 613 of the user monitoring device 61 determines the first signal 670Whether the first power measurement value P1 exceeds a threshold value. If the first power measurement value P1 of the first signal 670 exceeds the threshold value, this means that the user monitoring device 61 can correctly receive the communication data DATA1 from the first user equipment 67. Therefore, the user monitoring device 61 can directly monitor the communication data DATA1 of the first user device 67 based on the first identification code ID1 and the group identification code GID.
另一方面，若第一訊號670之第一功率量測值P1不超過臨限值，則此意味著，使用者監聽設備61可能不能自第一使用者設備67正確地接收通訊資料DATA1，乃因自第一使用者設備67所接收之功率並不好至足以達及使用者監聽設備61。因此，應提高第一使用者設備67之傳送功率。On the other hand, if the first power measurement value P1 of the first signal 670 does not exceed the threshold value, this means that the user monitoring device 61 may not correctly receive the communication data DATA1 from the first user equipment 67. The power received from the first user device 67 is not good enough to reach the user listening device 61. Therefore, the transmission power of the first user equipment 67 should be increased.
因此，使用者監聽設備61之處理器613基於第一功率量測值P1不超過臨限值之判定而藉由收發器611、經由eNB 65向管理伺服器63傳送功率調整請求610，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送功率調整命令650，以調整第一使用者設備67之傳送功率。隨後，在第十五實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1及群組辨識碼GID而藉由收發器611自第一使用者設備67正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits the power adjustment request 610 to the management server 63 via the eNB 65 based on the determination that the first power measurement value P1 does not exceed the threshold value, and causes the management to be managed. The server 63 notifies the eNB 65 that the power adjustment command 650 should be transmitted to the first user equipment 67 to adjust the transmission power of the first user equipment 67.

參照第16圖，其顯示例示本發明一第十六實施例之一3GPP直接模式通訊系統10之示意圖。應尤其瞭解，第十六實施例具有與第十一實施例相同之系統架構及相同之網路連接環境，因此具有相同參考編號之組件亦具有相同之功能且將不在本文中更加以說明。第十六實施例與前述實施例之不同在於，存在複數個用於監聽之使用者監聽設備。Referring to Fig. 16, there is shown a schematic diagram illustrating a 3GPP direct mode communication system 10 of a sixteenth embodiment of the present invention. It is to be understood that the sixteenth embodiment has the same system architecture and the same network connection environment as the eleventh embodiment, and therefore components having the same reference numerals have the same functions and will not be further described herein. The sixteenth embodiment differs from the previous embodiment in that there are a plurality of user listening devices for monitoring.
具體而言，在第十六實施例中，在3GPP直接模式通訊系統10中存在用於監聽第一使用者設備67之通訊之複數個合法使用者監聽設備(其包含使用者監聽設備61、70及71)。可如下達成合法監聽。Specifically, in the sixteenth embodiment, in the 3GPP direct mode communication systemThere are a plurality of legitimate user listening devices (which include user listening devices 61, 70 and 71) for monitoring the communication of the first user device 67. Legal interception can be achieved as follows.
首先，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65向管理伺服器63註冊成欲進行合法監聽。然後，管理伺服器63之處理器633藉由收發器631直接傳送一授權訊息632以授權使用者監聽設備61來執行合法監聽，且授權訊息632包含第一使用者設備67之第一辨識碼ID1。換言之，在第十六實施例中，授權程序之回饋直接包含第一辨識碼ID1。First, the processor 613 of the user monitoring device 61 registers with the management server 63 via the transceiver 611 via the eNB 65 to perform lawful interception. Then, the processor 633 of the management server 63 directly transmits an authorization message 632 by the transceiver 631 to authorize the user to monitor the device 61 to perform lawful interception, and the authorization message 632 includes the first identification code ID1 of the first user device 67. . In other words, in the sixteenth embodiment, the feedback of the authorization program directly includes the first identification code ID1.
類似地，使用者監聽設備70及71經由eNB 65向管理伺服器63註冊成欲進行合法監聽。然後，管理伺服器63藉由收發器631直接傳送授權訊息632以亦授權使用者監聽設備70及71來執行合法監聽。Similarly, user listening devices 70 and 71 are registered with management server 63 via eNB 65 for legitimate interception. The management server 63 then directly transmits the authorization message 632 via the transceiver 631 to also authorize the user to listen to the devices 70 and 71 to perform lawful interception.
接下來，使用者監聽設備61之處理器613基於第一辨識碼ID1而藉由收發器613自第一使用者設備67量測第一訊號670，並將第一訊號670之第一功率量測值P1報告至管理伺服器63。類似地，使用者監聽設備70及71基於第一辨識碼ID1而自第一使用者設備67量測第一訊號670，並將第一訊號670之不同功率量測值P1’及P1”報告至管理伺服器63。Next, the processor 613 of the user monitoring device 61 measures the first signal 670 from the first user device 67 by using the transceiver 613 based on the first identification code ID1, and measures the first power of the first signal 670. The value P1 is reported to the management server 63. Similarly, the user monitoring devices 70 and 71 measure the first signal 670 from the first user device 67 based on the first identification code ID1, and report the different power measurement values P1' and P1 of the first signal 670 to Management server 63.
隨後，管理伺服器63之處理器633則自功率量測值P1、P1’及P1”中確定具有較佳通訊品質之一功率量測值。在第十六實施例中，管理伺服器63選擇第一功率量測值P1。因此，此意味者，對於監聽第一使用者設備67而言具有較佳條件之使用者監聽設備係為使用者監聽設備61。Subsequently, the processor 633 of the management server 63 determines a power measurement value having a better communication quality from the power measurement values P1, P1' and P1". In the sixteenth embodiment, the management server 63 selects The first power measurement value P1. Therefore, this means that the user monitoring device having better conditions for monitoring the first user device 67 is the user monitoring device 61.
然後，管理伺服器63之處理器633藉由收發器631傳送一通知訊息634，以向使用者監聽設備61指示應監聽第一使用者設備67。另一方面，使用者監聽設備61之處理器613藉由收發器611接收應監聽第一使用者設備67之通知訊息634。隨後，在第十六實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67正確地監聽通訊資料DATA1。The processor 633 of the management server 63 then transmits a notification message 634 via the transceiver 631 to indicate to the user listening device 61 that the first user device 67 should be monitored. anotherIn one aspect, the processor 613 of the user listening device 61 receives, via the transceiver 611, a notification message 634 that should listen to the first user device 67. Subsequently, in the sixteenth embodiment, the processor 613 of the user listening device 61 can correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
應注意，在第十六實施例中，若使用者監聽設備61無法自第一使用者設備67正確地監聽通訊資料DATA1，則此意味著，自第一使用者設備67所接收之功率並不好至足以使第一使用者設備67達及使用者監聽設備61。因此，應提高第一使用者設備67之傳送功率。It should be noted that in the sixteenth embodiment, if the user listening device 61 cannot correctly monitor the communication data DATA1 from the first user device 67, this means that the power received from the first user device 67 is not It is good enough for the first user device 67 to reach the user listening device 61. Therefore, the transmission power of the first user equipment 67 should be increased.
因此，使用者監聽設備61之處理器613藉由收發器611、經由eNB 65直接向管理伺服器63傳送功率調整請求610，俾使管理伺服器63通知eNB 65應向第一使用者設備67傳送功率調整命令650，以調整第一使用者設備67之傳送功率。隨後，在第十六實施例中，使用者監聽設備61之處理器613能夠基於第一辨識碼ID1而藉由收發器611自第一使用者設備67正確地監聽通訊資料DATA1。Therefore, the processor 613 of the user monitoring device 61 transmits the power adjustment request 610 directly to the management server 63 via the eNB 65 via the eNB 65, so that the management server 63 notifies the eNB 65 that the eNB 65 should transmit to the first user equipment 67. The power adjustment command 650 is to adjust the transmit power of the first user equipment 67. Subsequently, in the sixteenth embodiment, the processor 613 of the user listening device 61 can correctly listen to the communication material DATA1 from the first user device 67 by the transceiver 611 based on the first identification code ID1.
應注意，在第十六實施例中，若另一使用者監聽設備70或71可在第一使用者設備67之功率不被調整之情形下繼續合法監聽，則管理伺服器63可向使用者監聽設備61傳送應停止合法監聽之一通知訊息。It should be noted that in the sixteenth embodiment, if another user listening device 70 or 71 can continue to legally monitor in the case where the power of the first user device 67 is not adjusted, the management server 63 can provide the user with the user. The listening device 61 transmits a notification message that should stop legal listening.

Step 1709 is executed to notify the eNB that the eNB should transmit a power adjustment command to the first user equipment to adjust the transmission power of the first user equipment. Then, step 1707 is executed to monitor the communication data of the first user equipment by the user monitoring device.
應注意，在監聽通訊資料之後，可更執行步驟1705，以重複功率調整方案，進而使使用者監聽設備連續且正確地監聽第一使用者設備之通訊資料。It should be noted that after the communication data is monitored, step 1705 may be further performed to repeat the power adjustment scheme, so that the user monitoring device continuously and correctly monitors the communication data of the first user equipment.

A flowchart of the lawful interception method is shown in FIG. The lawful interception method of the eighteenth embodiment is for use in a 3GPP direct mode communication system (e.g., the 3GPP direct mode communication system of the foregoing embodiment). The 3GPP direct mode communication system includes a user monitoring device and a management serverAnd an eNB. The steps of the eighteenth embodiment are detailed as follows.
首先，執行步驟1801，以由使用者監聽設備經由eNB向管理伺服器註冊成欲進行合法監聽。然後，執行步驟1802，以由管理伺服器授權使用者監聽設備來執行合法監聽。執行步驟1803，以由管理伺服器經由eNB向使用者監聽設備傳送一肯定監聽訊息。在步驟1803之後，執行步驟1804，以由使用者監聽設備經由eNB自管理伺服器接收肯定監聽訊息。該肯定監聽訊息包含一第一使用者設備之一第一辨識碼。First, step 1801 is performed to be registered by the user monitoring device to the management server via the eNB to perform lawful interception. Then, step 1802 is performed to authorize the user to listen to the device by the management server to perform lawful interception.

類似地，在第十八實施例中，在監聽通訊資料之後，可更執行步驟1805，以重複功率調整方案，進而使使用者監聽設備連續且正確地監聽第一使用者設備之通訊資料。然而，應注意，在第十八實施例中，並非使用訊號之功率量測值，而是可使用通訊資料之功率量測值來與臨限值進行比較。Similarly, in the eighteenth embodiment, after the communication data is monitored, step 1805 may be further performed to repeat the power adjustment scheme, so that the user monitoring device continuously and correctly monitors the communication data of the first user equipment. However, it should be noted that in the eighteenth embodiment, instead of using the power measurement value of the signal, the power measurement value of the communication data can be used to compare with the threshold value.
