私有小区信息下发方法和更新方法及通信网络和终端Private cell information issuing method and updating method, communication network and terminal

技术领域technical field

本发明涉及无线通信网络领域，特别涉及私有小区信息下发方法、私有小区信息更新的方法、通信网络和终端。The invention relates to the field of wireless communication networks, in particular to a method for issuing private cell information, a method for updating private cell information, a communication network and a terminal.

背景技术Background technique

随着通信技术的发展，用户需求随着移动通信系统的发展越来越多样化，系统设备为了适应这种需求也出现多样化，备受关注的家庭室内覆盖和企业级的内部覆盖基站以及一些其他私有网络应运而生。这种网络可以是家庭基站(Home NodeB)，家庭小区(Home Cell)，接入点(Access Point)，私有小区(Private Cell)等。由于只允许某些具有该网络权限的用户驻留或接入，同时会要求这些用户能在公网中驻留或接入，所以这些网络可以统称为私有网络。With the development of communication technology, user needs are becoming more and more diversified with the development of mobile communication systems, and system equipment is also diversifying to meet this demand. Home indoor coverage and enterprise-level internal coverage base stations and some Other private networks emerged. This kind of network can be Home NodeB, Home Cell, Access Point, Private Cell, etc. Because only certain users with the network authority are allowed to reside or access, and these users are required to reside or access in the public network, these networks can be collectively referred to as private networks.

在通用移动通信系统(UMTS)中，终端(UE)处于空闲(idle)状态、小区寻呼信道状态(CELL_PCH)、注册区域寻呼信道状态(URA_PCH)或小区前向接入信道状态(CELL_FACH)等状态下时，当系统的广播消息发生变化时，网络侧使用值标签(value tag)来标识系统消息的改变，当发现系统消息改变后，使用寻呼类型1或系统消息改变指示信息在所有终端寻呼时机下发该value tag，以通知所有的UE重选读取系统广播，更新其中的小区信息。当UE处在CELL_DCH状态下时，网络侧可以使用测量控制信息来通知UE关于CELL_DCH状态下切换使用的小区信息。In the Universal Mobile Telecommunications System (UMTS), the terminal (UE) is in idle state, cell paging channel state (CELL_PCH), registration area paging channel state (URA_PCH) or cell forward access channel state (CELL_FACH) In the waiting state, when the broadcast message of the system changes, the network side uses the value tag to identify the change of the system message. The terminal sends the value tag when paging to notify all UEs to reselect to read the system broadcast and update the cell information in it. When the UE is in the CELL_DCH state, the network side can use the measurement control information to notify the UE of information about the cell used for handover in the CELL_DCH state.

在UMTS中，小区信息有同频，异频，异系统小区，当UE从CELL_DCH到空闲态，从CELL_DCH到CELL_FACH，CELL_PCH，URA_PCH时，或者当UE在空闲态以及CELL_FACH，CELL_PCH，URA_PCH下，或者UE发生了小区变更时，都需要重新读取系统广播消息，其之前获取的小区信息的都会被清除掉。In UMTS, the cell information includes the same frequency, different frequency, and different system cells. When the UE goes from CELL_DCH to idle state, from CELL_DCH to CELL_FACH, CELL_PCH, URA_PCH, or when the UE is in idle state and CELL_FACH, CELL_PCH, URA_PCH, or When the UE changes its cell, it needs to read the system broadcast message again, and all the cell information obtained before will be cleared.

由于系统广播负载的限制，广播上每次修改的内容是一个或一组UE相关的，这时候把所有的UE都唤醒去读取更新的系统广播，一方面由于在所有UE的寻呼时刻下发更新的私有小区信息，严重增大了小区广播的负担。Due to the limitation of the system broadcast load, each modified content on the broadcast is related to one or a group of UEs. At this time, all UEs are woken up to read the updated system broadcast. On the one hand, due to the paging time of all UEs Sending updated private cell information seriously increases the burden of cell broadcasting.

另一方面，对于UE的省电是不利的，且更重要的是，UE获取到别的UE的私有小区是没有用的，由于接入限制，即使该UE有别的UE对应的私有小区的列表，也是无法使用别的小区的资源，造成了对终端中存储资源的浪费。On the other hand, it is unfavorable for the UE to save power, and more importantly, it is useless for the UE to obtain private cells of other UEs. Due to access restrictions, even if the UE has private cells corresponding to other UEs The list also cannot use the resources of other cells, resulting in a waste of storage resources in the terminal.

且由于UE支持的小区信息是相对恒定而且小区数量比较少，所以当UE在空闲态和连接态的状态转换或者在连接态的内部的状态转换的过程中，私有小区发生变化的概率都是比较小的，因此，在这些过程中，删除UE中的私有小区信息，造成了对UE处理资源的浪费。And since the cell information supported by the UE is relatively constant and the number of cells is relatively small, when the UE is in the state transition between the idle state and the connected state or in the process of the internal state transition in the connected state, the probability of the private cell changing is relatively high. Small, therefore, in these processes, the private cell information in the UE is deleted, causing a waste of UE processing resources.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明作进一步的详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

本发明实施例中，在终端的寻呼时机，向所述终端下发私有小区信息更新指示；并根据该指示，在对应的消息中携带私有小区信息，该私有小区信息仅包括所述终端对应的私有小区信息。这种方案适用于无法通过专有消息或专有信令，只能通过除上述终端外其他终端也能够收到等广播消息等消息下发私有小区信息等情况。In the embodiment of the present invention, at the paging occasion of the terminal, an instruction to update the private cell information is sent to the terminal; and according to the instruction, the private cell information is carried in the corresponding message, and the private cell information only includes the corresponding private community information. This solution is applicable to situations where private cell information cannot be sent through proprietary messages or proprietary signaling, but can only be sent through messages such as broadcast messages received by other terminals besides the above-mentioned terminals.

上述终端的状态，可以为位置区域可知状态，如idle状态，或寻呼区域可知状态，如URA_PCH状态，或小区可知状态，如CELL_PCH状态或CELL_FACH状态。在不同的状态下，下发上述更新指示和私有小区信息的方式也可以有所不同，且下发的私有小区信息的获取方式也可以不同。以下通过具体实施例进行详细说明。The state of the above-mentioned terminal may be a location area-aware state, such as an idle state, or a paging area-aware state, such as a URA_PCH state, or a cell-aware state, such as a CELL_PCH state or a CELL_FACH state. In different states, the manners of issuing the above-mentioned update instruction and private cell information may also be different, and the manners of obtaining the issued private cell information may also be different. The following will be described in detail through specific examples.

本发明的实施例中，还可以将下发给终端的专有信令中携带的私有小区信息，设置为仅包括该终端对应的私有小区信息。In the embodiment of the present invention, the private cell information carried in the dedicated signaling delivered to the terminal may also be set to include only the private cell information corresponding to the terminal.

本发明实施例中，由于在消息或信令中仅下发个别终端对应的私有小区信息，在保证该终端能够及时更新自身中的私有小区信息的同时，又防止了对传输资源的浪费。In the embodiment of the present invention, since only the private cell information corresponding to an individual terminal is sent in the message or signaling, while ensuring that the terminal can update its own private cell information in time, it also prevents waste of transmission resources.

在本发明方法的第一实施例中，由于每个UE相关的私有小区在核心网保存，对于处于CELL_PCH，URA_PCH状态下的UE，UTRAN中的无线网络控制器(RNC)在下发该UE的私有小区信息之前，从核心网(CN)获得关于该UE的私有小区信息。In the first embodiment of the method of the present invention, since the private cell related to each UE is stored in the core network, for the UE in the state of CELL_PCH and URA_PCH, the radio network controller (RNC) in UTRAN issues the private cell of the UE. Before the cell information, the private cell information about the UE is obtained from the core network (CN).

如图1所示，RNC和核心网的交互流程包括：As shown in Figure 1, the interaction process between the RNC and the core network includes:

步骤11、RNC向CN发送初始终端消息(INITIAL UE MESSAGE)，该消息中包括增加的一个信元(IE)：获取小区信息(GetPriCellInfo)，其值为获取(get)，或不需要获取(no need to get)。Step 11, RNC sends initial terminal message (INITIAL UE MESSAGE) to CN, includes an information element (IE) that increases in this message: obtain cell information (GetPriCellInfo), its value is to obtain (get), or does not need to obtain (no need to get).

步骤12、CN根据初始终端消息中的获取小区信息信元值，在确定出该值为get时，向RNC返回一条响应消息，该消息中包括的私有小区信息为上述UE支持的私有节点(Home NodeB)参数列表。该HNB的参数列表中包括以下六种信息之一，或该六种信息的任意组合：私有节点标识id、私有小区id、私有小区扰码、私有小区的位置信息、私有节点的频率、私有节点的无线接入技术(RAT)信息。Step 12, CN returns a response message to RNC according to the obtained cell information information element value in the initial terminal message when determining that the value is get, and the private cell information included in the message is the private node (Home Node) supported by the above-mentioned UE NodeB) parameter list. The HNB parameter list includes one of the following six types of information, or any combination of the six types of information: private node identification id, private cell id, private cell scrambling code, private cell location information, private node frequency, private node radio access technology (RAT) information.

CN也可以将该HNB参数列表携带在其他发送给RNC的消息中。The CN may also carry the HNB parameter list in other messages sent to the RNC.

或者，本实施例中，还可以由CN在确定出UE的私有小区列表发生变化后，向该小区所在的UTRAN中的RNC下发该UE的私有小区列表。而对于idle状态的UE，UE的位置在小区级别是不可知的，因此CN需要向该终端所在位置区/路由区(LA/RA)内所有UTRAN中的RNC下发该UE的私有小区列表。Alternatively, in this embodiment, after determining that the private cell list of the UE has changed, the CN may send the UE's private cell list to the RNC in the UTRAN where the cell is located. For a UE in the idle state, the location of the UE is unknown at the cell level, so the CN needs to send the private cell list of the UE to the RNCs in all UTRANs in the location area/routing area (LA/RA) where the terminal is located.

另外，在上述步骤12之前，CN也可以主动将终端的初始私有小区列表下发给RNC。In addition, before the above step 12, the CN may also actively deliver the terminal's initial private cell list to the RNC.

在RNC从CN获取了UE的私有小区列表后，需要根据UE的不同状态，在不同的信道中下发上述私有小区列表更新指示和更新的私有小区列表。After the RNC acquires the UE's private cell list from the CN, it needs to issue the above private cell list update instruction and the updated private cell list in different channels according to different states of the UE.

首先，对于idle状态的UE，获取到UE私有小区列表的LA/RA内所有UTRAN中的RNC，在该UE的寻呼时机(paging occasion)，把该UE对应的私有小区列表更新在小区广播消息中，并且只在该UE的paging occasion通过寻呼信道发送的寻呼消息把广播信道(BCCH)变化的value tag值指示下去。因为小区并不知道UE是否驻留在该小区上，而且UE更换小区后，会清除其在别的小区读取的小区列表的信息，所以LA/RA的UTRAN内的小区需要周期性的在UE对应的寻呼时机中指示UE读取其更新的小区广播。则UE在读取到包括更新的私有小区列表的广播消息后，根据其中的私有小区列表更新自身中的私有小区列表。First, for the UE in the idle state, all RNCs in the UTRAN in the LA/RA of the private cell list of the UE are obtained, and at the paging occasion of the UE, the private cell list corresponding to the UE is updated in the cell broadcast message , and only in the paging occasion of the UE, the paging message sent through the paging channel indicates the value tag value of the broadcast channel (BCCH) change. Because the cell does not know whether the UE is camped on the cell, and after the UE changes the cell, it will clear the information of the cell list read in other cells, so the cells in the UTRAN of LA/RA need to be periodically registered in the UE. In the corresponding paging occasion, the UE is instructed to read its updated cell broadcast. After reading the broadcast message including the updated private cell list, the UE updates its own private cell list according to the private cell list therein.

由于一组UE可能处于一个UTRAN中，且具有相同的寻呼时机，所以对于这样一组UE，UTRAN可以在这组UE的寻呼时机，广播该组UE对应的私有小区列表。Since a group of UEs may be in one UTRAN and have the same paging occasion, for such a group of UEs, the UTRAN may broadcast the private cell list corresponding to the group of UEs at the paging occasion of the group of UEs.

相对于在所有的寻呼时机指示系统消息改变的现有技术方案，由于只在需要更新系统消息的UE的寻呼时机下发寻呼指示，对BCCH的负载有很大的减轻。Compared with the prior art solution in which the system information is changed at all paging occasions, since the paging indication is only sent at the paging occasion of the UE that needs to update the system information, the load on the BCCH is greatly reduced.

其次，对于URA_PCH状态的UE，其位置在URA内是可知的，则该URA内的UTRAN中的RNC在某一个或某一组UE的paging occasion，在所属所有小区中通过寻呼信道发送的寻呼消息携带value tag，并在对应paging occasion的广播消息中携带这些UE对应的私有小区列表，UE在接收到该广播消息后，更新自身中的私有小区列表。由于URA的范围比LA/RA的范围小，这种情况下，系统广播开销的浪费更少一些。Secondly, for the UE in the URA_PCH state, its location is known in the URA, then the RNC in the UTRAN in the URA sends paging occasions through the paging channel in all cells to which it belongs. The paging message carries the value tag, and the broadcast message corresponding to the paging occasion carries the private cell list corresponding to these UEs. After receiving the broadcast message, the UE updates the private cell list in itself. Since the range of URA is smaller than that of LA/RA, in this case, the waste of system broadcast overhead is less.

再次，对于CELL_PCH状态下的UE，其位置是小区可知的。UTRAN只需在一个或一组UE的paging occasion，在这些UE所在小区中通过寻呼信道发送的寻呼消息携带value tag，并在对应paging occasion的广播消息中携带这些UE对应的私有小区列表，则UE只需要读取当前驻留小区广播的关于该UE的私有小区列表的广播消息一次，并根据接收该广播消息中的私有小区列表，更新自身中的私有小区列表。Again, for the UE in the CELL_PCH state, its location is known by the cell. UTRAN only needs to carry the value tag in the paging message sent through the paging channel in the paging occasion of one or a group of UEs in the cell where these UEs are located, and carry the private cell list corresponding to these UEs in the broadcast message corresponding to the paging occasion, Then the UE only needs to read the broadcast message about the UE's private cell list broadcast by the cell where it currently resides, and update its own private cell list according to the private cell list received in the broadcast message.

此后，对处于CELL_FACH状态下的UE，UE的位置在小区级别是可知的，UTRAN只需在UE的paging occasion，在所在小区的小区广播消息中下发UE对应的私有小区列表，则UE只需要读取当前驻留小区关于该UE的私有小区列表的更新消息一次。与前几种情况不同的是，私有小区更新指示通过系统消息改变指示(SYSTEM INFORMATION CHANGEINDICATION)消息来通知，而不是通过上述value tag来通知。Afterwards, for the UE in the CELL_FACH state, the location of the UE is known at the cell level. UTRAN only needs to send the corresponding private cell list of the UE in the cell broadcast message of the cell where the UE is located, and the UE only needs to Read the update message about the UE's private cell list of the cell currently camped on once. The difference from the previous cases is that the private cell update instruction is notified through the SYSTEM INFORMATION CHANGEINDICATION message instead of the above value tag.

本实施例中，对上述各种状态下的UE，在通过广播消息发送更新的私有小区信息时，该广播消息中可以包含对应UE的标识，则接收到广播消息到UE需要先检测广播消息中的UE标识是否与自身的标识一致，如果一致，再读取广播消息。这样在多个UE具有相同的寻呼时机时，网络侧就可以仅发送一个UE对应的私有小区信息，且也能够保证其他UE不会误收该私有小区信息，从而使这些UE进行不必要的处理。In this embodiment, for UEs in the above-mentioned various states, when the updated private cell information is sent through a broadcast message, the broadcast message may contain the identifier of the corresponding UE, and the UE needs to detect the information in the broadcast message before receiving the broadcast message. Check whether the UE ID of the UE is consistent with its own ID, and if so, read the broadcast message. In this way, when multiple UEs have the same paging opportunity, the network side can only send the private cell information corresponding to one UE, and it can also ensure that other UEs will not receive the private cell information by mistake, so that these UEs do unnecessary deal with.

在第一实施例中，对处于idle状态、URA_PCH状态、CELL_PCH状态和CELL_FACH状态的UE，如何下发UE的私有小区列表，以及如何更新其中的私有小区列表进行了说明。在第二实施例中，对CELL_DCH状态下对UE如何更新其私有小区列表进行说明。In the first embodiment, how to deliver the UE's private cell list and how to update the private cell list is described for the UE in the idle state, URA_PCH state, CELL_PCH state and CELL_FACH state. In the second embodiment, how to update the private cell list of the UE in the CELL_DCH state is described.

对于激活状态(active)，也即CELL_DCH状态的UE，可以通过专用控制信道下发专用控制消息来修改UE的测量小区列表，从而实现active状态下的移动性。如果idle状态下的UE并不要求支持hNB的话，那么也可以直接使用专用控制消息将UE支持的私有小区列表发送给UE，让UE进行移动性处理。For a UE in an active state (active), that is, a UE in a CELL_DCH state, a dedicated control message may be sent through a dedicated control channel to modify the measurement cell list of the UE, thereby realizing mobility in the active state. If the UE in the idle state does not require to support hNB, it can also directly use a dedicated control message to send the list of private cells supported by the UE to the UE, so that the UE can perform mobility processing.

UE使用专用信令来获取私有小区列表的场景如下：The scenarios where the UE uses dedicated signaling to obtain the list of private cells are as follows:

场景一：UE附着(attach)网络或者发起RRC连接建立的过程中，从核心网获得UE支持的私有小区的信息，如图2所示，具体包括如下步骤：Scenario 1: During the process of UE attaching to the network or initiating RRC connection establishment, the information of the private cell supported by the UE is obtained from the core network, as shown in Figure 2, which specifically includes the following steps:

步骤21-22、UE发起RRC连接请求或者attach，通过UTRAN建立RRC连接和Iu连接到核心网。Step 21-22, UE initiates RRC connection request or attach, establishes RRC connection and Iu connection to core network through UTRAN.

步骤23-24、CN通过下行信令把UE支持的私有小区的信息发送给UE。In steps 23-24, the CN sends the information of the private cells supported by the UE to the UE through downlink signaling.

这里，如果采用的是非接入层(NAS)信令，则UTRAN透传CN的包括私有小区信息的消息到UE，告知其包含的UE的私有小区信息。如果是采用接入层(AS)信令，UTRAN通过专用信令，如测量控制消息，或者通过信令夹带的方式把UE的私有小区信息发送给UE，并且该专用信令中仅携带该UE的私有小区信息，不包括其他UE的私有小区信息。Here, if Non-Access Stratum (NAS) signaling is used, the UTRAN transparently transmits the CN message including the private cell information to the UE, and notifies the UE of the private cell information contained therein. If access stratum (AS) signaling is used, UTRAN sends the UE’s private cell information to the UE through dedicated signaling, such as measurement control messages, or through signaling entrainment, and the dedicated signaling only carries the UE The private cell information of the UE does not include the private cell information of other UEs.

步骤25、UE接收到私有小区信息后，将该信息填写进其保存的小区列表中，并根据该列表进行测量和测量结果的上报。Step 25. After receiving the private cell information, the UE fills in the information into its stored cell list, and performs measurement and reports the measurement results according to the list.

场景二：当UE在连接态进行移动性管理时，其支持的私有小区的信息也在网络间传递。例如UE发生跨RNC切换时，其私有小区的信息在SRNS重定位消息中传递，具体如图3所示，该流程包括：Scenario 2: When the UE performs mobility management in the connected state, the information of the private cells it supports is also transmitted between networks. For example, when the UE undergoes cross-RNC handover, the information of its private cell is transmitted in the SRNS relocation message, as shown in Figure 3. The process includes:

步骤31-32、源RNC向目标RNC发送重定位请求消息，通过CN的转发。Steps 31-32, the source RNC sends a relocation request message to the target RNC, which is forwarded by the CN.

由于UE的源RNC中可以有其从CN中获取的UE私有小区信息，所以源RNC发送的重定位请求中可以直接包括私有小区信息。当然，源RNC发送的私有小区信息也可以由CN在转发重定位请求消息时，将对应UE的私有小区信息设置在该消息中发送给目标RNC，这种情况下，源RNC发送给CN的重定位请求消息中可以包括一私有小区信息请求信息，则CN根据该信息设置UE的私有小区信息。Since the UE's source RNC may have UE private cell information acquired from the CN, the relocation request sent by the source RNC may directly include the private cell information. Of course, the private cell information sent by the source RNC can also be sent to the target RNC by setting the private cell information of the corresponding UE in the message when the CN forwards the relocation request message. In this case, the relocation request message sent by the source RNC to the CN The location request message may include private cell information request information, and the CN sets the private cell information of the UE according to the information.

步骤33-34、目标RNC会通过CN向源RNC发送重定位命令。In steps 33-34, the target RNC sends a relocation command to the source RNC through the CN.

以上两个实施例中，对网络侧如何向UE下发私有小区信息，以及UE根据这些私有小区信息更新自身中的小区信息进行了说明。在上述两个实施例的基础上，网络侧还可以在确定出需要删除终端中的私有小区信息后，向终端发送删除私有小区信息命令，则终端接收到该命令后，根据该命令删除自身中的对应私有小区信息。该私有小区信息命令可以是要求终端删除全部的私有小区信息，则终端根据该命令直接删除全部私有小区信息；也可以是要求终端删除部分私有小区信息，则终端根据该命令中删除对应部分的私有小区信息。In the above two embodiments, how the network side issues private cell information to the UE, and how the UE updates its own cell information according to the private cell information is described. On the basis of the above two embodiments, after the network side determines that the private cell information in the terminal needs to be deleted, it can send a command to delete the private cell information to the terminal. After receiving the command, the terminal deletes the private cell information in itself according to the command. The corresponding private cell information. The private cell information command may be to request the terminal to delete all private cell information, and the terminal will directly delete all private cell information according to the command; it may also be to request the terminal to delete part of private community information.

网络侧也可以在接收到终端上报的私有小区信息删除请求后，根据该请求生成上述私有小区删除命令，并将该命令下发给终端。The network side may also generate the private cell deletion command according to the request after receiving the private cell information deletion request reported by the terminal, and issue the command to the terminal.
