However, in the process of using these information to identify the user equipment, the problem of time accuracy between the first access device and the second access device is not considered. In the process of identifying the user equipment, it is often impossible to accurately identify the user equipment. to identify.
图1A是本发明实施例一方面提供的一种通信方法的示意性流程图，该方法用于第一接入设备和第二接入具有不同制式的通信系统中，如图1A所示，该方法包括以下内容。Fig. 1A is a schematic flowchart of a communication method provided by an aspect of an embodiment of the present invention. The method is used in a communication system in which the first access device and the second access device have different standards. As shown in Fig. 1A, the Methods include the following.
101，第一接入设备使用第二接入设备的下行频点接收第二接入设备广播的定时信息，并根据定时信息与第二接入设备进行系统帧同步，以使得第一接入设备在与第二接入设备进行系统帧同步的情况下，对用户设备进行监听。101. The first access device uses the downlink frequency of the second access device to receive timing information broadcast by the second access device, and performs system frame synchronization with the second access device according to the timing information, so that the first access device In the case of performing system frame synchronization with the second access device, monitor the user equipment.
可选地，该定时信息可以是第二接入设备各个系统帧的帧号所对应的时间，也就是各个系统帧所对应的时间。从而，第一接入设备在获取了第二接入设备各个系统帧所对应的时间，进行与第二接入设备系统帧的同步，第一接入设备可以在第二接入设备系统帧所对应的时间去监听用户设备。Optionally, the timing information may be the time corresponding to the frame number of each system frame of the second access device, that is, the time corresponding to each system frame. Therefore, after the first access device obtains the time corresponding to each system frame of the second access device, it synchronizes with the system frame of the second access device, and the first access device can The corresponding time to monitor the user equipment.
102，第一接入设备获取用户设备的时域位置信息，其中该用户设备为当前接入第二接入设备的用户设备。102. The first access device acquires time-domain location information of a user equipment, where the user equipment is a user equipment currently accessing a second access device.
103，第一接入设备根据用户设备的时域位置信息识别用户设备。103. The first access device identifies the user equipment according to the time domain location information of the user equipment.
可选的，上述时域位置信息包括上述用户设备与系统帧的映射关系。例如，用户设备可以占用整个系统帧进行上行数据传输。第二接入设备可以通知第一接入设备用户设备与系统帧的映射关系为，UE1在系统帧1上进行上行数据传输，UE2在系统帧2上进行上行数据传输。由于在101中，第一接入设备与第二接入设备已经进行了系统帧同步，第一接入设备会在对系统帧1所对应的时间和系统帧2所对应的时间分别对用户设备进行监听，因而第一接入设备根据该映射关系可以在系统帧1上监听到进行上行数据传输的用户设备为UE1，以及在系统帧2上监听到进行上行数据传输的用户设备为UE2，从而识别出UE1和UE2。Optionally, the time domain location information includes the mapping relationship between the user equipment and the system frame. For example, the user equipment may occupy the entire system frame for uplink data transmission. The second access device may notify the first access device that the mapping relationship between the user equipment and the system frame is that UE1 performs uplink data transmission on system frame 1, and UE2 performs uplink data transmission on system frame 2. Since in 101, the first access device and the second access device have synchronized the system frames, the first access device will synchronize the user equipment at the time corresponding to system frame 1 and the time corresponding to system frame 2 respectively. monitoring, so that the first access device can detect that the user equipment performing uplink data transmission on system frame 1 is UE1 according to the mapping relationship, and that the user equipment performing uplink data transmission on system frame 2 is UE2, thus UE1 and UE2 are identified.
更进一步，该用户设备与系统帧的映射关系具体可以是用户设备与每个系统帧中子帧的映射关系。作为一个示例，图1B为LTE系统帧结构示意图，一个系统帧为10毫秒（ms），一个系统帧包含10个子帧，这10个子帧具有10个固定编号，分别为#0，#1，#2，#3，#4，#5，#6，#7，#8和#9。在LTE系统中，用户设备在时域上通过子帧进行数据传输。在第二接入设备为LTE制式时，第一接入设备可以在与第二接入设备系统帧同步并通过获取的用户设备与每个系统帧中子帧的映射关系识别出监听的用户设备为哪个用户设备。例如，第二接入设备可以通知第一接入设备的系统帧与用户设备的映射关系为：在系统帧5中，UE0使用子帧#0发送上行数据，UE1使用子帧#3发送上行数据；在系统帧6中，UE2使用子帧#0发送上行数据，UE3使用子帧#1发送上行数据。由于第一接入设备和第二接入设备通过定时信息进行了系统帧同步，第一接入设备会在系统帧5所对应的时间和系统帧6所对应的时间分别对用户设备进行监听，并且，第一接入设备可以根据该系统帧与用户设备的映射关系，识别出在系统帧5的子帧#0上发送上行信号的用户设备为UE0，在系统帧5的子帧#3上发送上行信号的用户设备为UE1，在系统帧6的子帧#0上发送上行信号的用户设备为UE2，在系统帧6的子帧#1上发送上行数据的为UE3。Furthermore, the mapping relationship between the user equipment and the system frame may specifically be the mapping relationship between the user equipment and subframes in each system frame. As an example, Figure 1B is a schematic diagram of an LTE system frame structure. A system frame is 10 milliseconds (ms), and a system frame includes 10 subframes. These 10 subframes have 10 fixed numbers, respectively #0, #1, # 2, #3, #4, #5, #6, #7, #8 and #9. In the LTE system, user equipment performs data transmission in the time domain through subframes. When the second access device is of LTE standard, the first access device can synchronize with the system frame of the second access device and identify the monitored user equipment through the obtained mapping relationship between the user equipment and subframes in each system frame for which user device. For example, the second access device may notify the first access device that the mapping relationship between the system frame and the user equipment is: in system frame 5, UE0 uses subframe #0 to send uplink data, and UE1 uses subframe #3 to send uplink data ; In system frame 6, UE2 uses subframe #0 to send uplink data, and UE3 uses subframe #1 to send uplink data. Since the first access device and the second access device perform system frame synchronization through timing information, the first access device will monitor the user equipment at the time corresponding to system frame 5 and the time corresponding to system frame 6 respectively, In addition, the first access device may recognize that the user equipment that sends the uplink signal on subframe #0 of system frame 5 is UE0, and that the user equipment that sends an uplink signal on subframe #3 of system frame 5 is The user equipment sending uplink signals is UE1, the user equipment sending uplink signals on subframe #0 of system frame 6 is UE2, and the user equipment sending uplink data on subframe #1 of system frame 6 is UE3.
更进一步，本发明实施例提供的技术方案，在进行系统帧同步后，根据用户设备的时域位置信息对用户设备在时域上进行准确识别的方法中，识别出来的用户设备可能仍然为多个，也就是说，识别出来的多个用户设备可能占用了相同的时域位置，即一个系统帧对应了多个用户设备或一个系统帧的一个子帧对应了多个用户设备。在需要对这识别出的多个用户设备进一步进行识别的情况下，第一接入设备还可进一步根据用户设备的频域位置信息进一步辨识出上述识别出的多个用户设备中每一个，例如，根据用户设备与子带（一个子带由至少一个物理资源块构成）的对应关系进一步辨识出用户设备。作为一个示例，假设占用系统帧5的子帧#0的用户设备包含UE1和UE2；占用系统帧6的子帧#1的用户设备包含UE3和UE4。第二接入设备进一步可以通知第一接入设备用户设备与子带的对应关系：UE1占用子带1，UE2占用子带2；UE3占用子带3和UE4占用子带4。第一接入设备可以根据定时信息进行系统帧同步后，根据时域位置信息和频域位置信息，识别所监听的用户设备中系统帧5的子帧#0上的使用子带1的用户设备为UE1，系统帧5的子帧#0上使用子带2的用户设备为UE2，系统帧6的子帧#1上使用子带3的用户设备为UE3，系统帧6的子帧#1上使用子带4的用户设备为UE4。Furthermore, in the technical solution provided by the embodiments of the present invention, after the system frame synchronization is performed, in the method of accurately identifying the user equipment in the time domain according to the time domain location information of the user equipment, the identified user equipment may still be multiple That is to say, multiple identified user equipments may occupy the same time domain position, that is, one system frame corresponds to multiple user equipments or one subframe of one system frame corresponds to multiple user equipments. In the case where it is necessary to further identify the multiple identified user equipments, the first access device may further identify each of the above identified multiple user equipments according to the frequency domain location information of the user equipments, for example , to further identify the user equipment according to the correspondence between the user equipment and the subbands (a subband is composed of at least one physical resource block). As an example, assume that user equipment occupying subframe #0 of system frame 5 includes UE1 and UE2; user equipment occupying subframe #1 of system frame 6 includes UE3 and UE4. The second access device may further notify the first access device of the correspondence between user equipment and subbands: UE1 occupies subband 1, UE2 occupies subband 2; UE3 occupies subband 3 and UE4 occupies subband 4. After performing system frame synchronization according to the timing information, the first access device can identify the user equipment using subband 1 on subframe #0 of system frame 5 among the monitored user equipment according to time domain position information and frequency domain position information For UE1, the user equipment using subband 2 on subframe #0 of system frame 5 is UE2, the user equipment using subband 3 on subframe #1 of system frame 6 is UE3, and the user equipment using subband 3 on subframe #1 of system frame 6 is UE3, and the user equipment using subband #1 on system frame 6 The user equipment using subband 4 is UE4.
在本发明实施例中，第二接入设备广播定时信息，接入第二接入设备的用户设备可以从广播信道上读取该定时信息，从而进行用户设备和第二接入设备的系统帧的同步，以便用户设备和第二接入设备使用同步的系统帧进行业务传输。由于第一接入设备和第二接入设备具有不同的制式，可以在第一接入设备上设置一个与第二接入设备具有相同制式的上行接收机，该上行接收机可以使用第二接入设备的下行频点接收第二接入设备广播的定时信息，从而进行第一接入设备与第二接入设备之间的系统帧的同步，以使得第一接入设备在系统帧所对应的时间去监听用户设备。由于第二接入设备与用户设备之间系统帧是同步的，因而，第一接入设备与用户设备之间的系统帧也是同步的。在第一接入设备与第二接入设备的系统帧同步的情况下，第一接入设备获取用户设备与系统帧的映射关系，并对用户设备的上行信号进行监听，并根据用户设备与系统帧的映射关系，在系统帧中识别出发送该上行信号的用户设备为哪个用户设备。In the embodiment of the present invention, the second access device broadcasts the timing information, and the user equipment accessing the second access device can read the timing information from the broadcast channel, so that the system frame of the user equipment and the second access device synchronization, so that the user equipment and the second access equipment use synchronized system frames for service transmission. Since the first access device and the second access device have different standards, an uplink receiver with the same standard as the second access device can be set on the first access device, and the uplink receiver can use the second The downlink frequency point of the access device receives the timing information broadcast by the second access device, so as to synchronize the system frame between the first access device and the second access device, so that the first access device time to monitor user equipment. Since the system frames between the second access device and the user equipment are synchronized, the system frames between the first access device and the user equipment are also synchronized. When the system frames of the first access device and the second access device are synchronized, the first access device obtains the mapping relationship between the user equipment and the system frame, monitors the uplink signal of the user equipment, and The mapping relationship of the system frame identifies which user equipment the user equipment sending the uplink signal is in the system frame.

Since in FDD mode, the uplink frequency of the user equipment is different from the downlink frequency of the second access device, the first access device can use the The uplink receiver of the same standard monitors the user equipment. In the process of monitoring the user equipment, the uplink receiver may switch from using the downlink frequency of the second access device to using the uplink frequency of the user equipment, thereby implementing monitoring of the user equipment. Since the system frames between the first access device and the user equipment are synchronized before monitoring the user equipment, the first access device can identify the user equipment according to the mapping relationship between the user equipment and the system frame.

可选地，在第一接入设备从第二接入设备接收定时信息之前，，第一接入设备可以通过空口接收第二接入设备发送的工作参数，该工作参数用于第一接入设备进行配置以便实现可以接收第二接入设备广播的定时信息并对用户设备进行监听等交互。该工作参数可以包括：第二接入设备的小区标识符（Physical Cell Identifier，PCI）、小区带宽、物理混合自动重传请求指示信道（Physical Hybrid ARQ Indicator Channel，PHICH）配置信息、天线数目、循环前缀（Cyclic Prefix，CP）长度、随机接入码和时隙、工作制式和工作频点等。其中，第二接入设备的PCI、小区带宽、PHICH配置信息、工作模式和工作频点用于第一接入设备通过空口从第二接入设备接收信息（例如第二接入设备广播的定时信息），随机接入码和时隙、工作模式和工作频点用于第一接入设备接收用户设备发送的上行信号。该工作参数还可以包括定时信息，以便第一接入设备在初始配置时就与第二接入设备在时间上进行系统帧的同步。或者，如果该工作参数不包括定时信息，则该第一接入设备可以在根据该工作参数进行配置之后与第二接入设备进行同步，以便与第二接入设备进行系统帧的同步，然后再对用户设备进行监听。第一接入设备在初始配置时就与第二接入设备进行系统帧同步，这样第一接入设备可以根据用户设备的时域位置信息确定用户设备。Optionally, before the first access device receives the timing information from the second access device, the first access device may receive the working parameters sent by the second access device through the air interface, and the working parameters are used for the first access The device is configured so that it can receive the timing information broadcast by the second access device and perform interactions such as listening to the user equipment. The working parameters may include: the cell identifier (Physical Cell Identifier, PCI) of the second access device, cell bandwidth, physical hybrid ARQ indicator channel (Physical Hybrid ARQ Indicator Channel, PHICH) configuration information, number of antennas, cycle Prefix (Cyclic Prefix, CP) length, random access code and time slot, working system and working frequency, etc. Among them, the PCI, cell bandwidth, PHICH configuration information, working mode, and working frequency of the second access device are used for the first access device to receive information from the second access device through the air interface (such as the timing of the broadcast by the second access device). Information), random access code and time slot, working mode and working frequency are used for the first access device to receive the uplink signal sent by the user equipment. The working parameters may also include timing information, so that the first access device and the second access device perform system frame synchronization in time during initial configuration. Or, if the working parameter does not include timing information, the first access device may synchronize with the second access device after being configured according to the working parameter, so as to perform system frame synchronization with the second access device, and then Then monitor the user equipment. The first access device performs system frame synchronization with the second access device during initial configuration, so that the first access device can determine the user equipment according to the time domain location information of the user equipment.
本发明实施例中，第二接入设备可以是宏基站，第一接入设备可以是位于该宏基站服务范围内的微（Micro）基站、微微（Pico）基站或WLAN AP等。该第一接入设备的工作模式和该第二接入设备相同，即如果第二接入设备的工作模式为FDD，则第一接入设备的工作模式也是FDD，如果第二接入设备的工作模式为TDD，则第一接入设备的工作模式也是TDD。In the embodiment of the present invention, the second access device may be a macro base station, and the first access device may be a micro (Micro) base station, pico (Pico) base station, or WLAN AP located within the service range of the macro base station. The working mode of the first access device is the same as that of the second access device, that is, if the working mode of the second access device is FDD, the working mode of the first access device is also FDD. If the working mode is TDD, the working mode of the first access device is also TDD.
进一步的，上述方法还可以包括：第一接入设备判断识别出的用户设备是否可以接入到该第一接入设备；并在第一接入设备判断出识别出的用户设备可以进入到该第一接入设备中时，将识别出的该用户设备接入到第一接入设备中，从而对第二接入设备进行分流。可选的，第一接入设备可以根据识别出的用户设备到该第一接入设备路损判断出是否可以接入到第一接入设备，例如，如果识别出的用户设备到该第一接入设备的路损小于指定的门限时，则请求第二接入设备将识别出的用户设备与该第二接入设备之间至少一个业务承载切换到第一接入设备，并在第二接入设备响应该请求后将用户设备与第二接入设备之间的至少一个业务承载切换到第一接入设备中，以便对第二接入设备进行分流。Further, the above method may further include: the first access device judges whether the identified user equipment can access the first access device; and when the first access device determines that the identified user equipment can access the When in the first access device, the identified user equipment is connected to the first access device, so as to offload the second access device. Optionally, the first access device may determine whether it is possible to access the first access device according to the path loss between the identified user equipment and the first access device, for example, if the identified user equipment reaches the first access device When the path loss of the access device is less than the specified threshold, request the second access device to switch at least one service bearer between the identified user equipment and the second access device to the first access device, and After responding to the request, the access device switches at least one service bearer between the user equipment and the second access device to the first access device, so as to offload the second access device.
应用本发明实施例提供的技术方案，第一接入设备通过接收第二接入设备广播的定时信息，第一接入设备与第二接入设备进行系统帧同步，使得第一接入设备与接入到第二接入设备的用户设备也进行了系统帧同步。第一接入设备根据从第二接入设备接收到的该用户设备时域位置信息，从该时域位置信息中识别出当前发送上行信号的具体用户设备。与现有技术相比，由于经过系统帧同步后使用用户设备的时域位置信息对用户设备进行识别具有较高的时间精度，可以更加准确的识别出用户设备。Applying the technical solution provided by the embodiment of the present invention, the first access device performs system frame synchronization with the second access device by receiving the timing information broadcast by the second access device, so that the first access device and the second access device The user equipment connected to the second access device also performs system frame synchronization. According to the time-domain location information of the user equipment received from the second access device, the first access device identifies the specific user equipment currently sending the uplink signal from the time-domain location information. Compared with the prior art, since the time domain position information of the user equipment is used to identify the user equipment after system frame synchronization has higher time precision, the user equipment can be identified more accurately.
图2A是本发明实施例提供的一种异构网络架构示意图，在该异构网络网络中，第一接入设备为使用WLAN制式的WLAN AP，第二接入设备为宏基站，WLAN AP和宏基站具有不同的制式，用户设备可以使用该不同的制式接入到WLAN AP或宏基站。在该异构网络中，宏基站为用户设备当前接入的基站，由宏基站提供业务服务。当用户设备移动到WLAN AP的信号覆盖范围内时，如果宏基站的负载较重，可以将用户设备与宏基站之间的至少一个业务承载切换到该WLAN AP中，从而分流宏基站中的数据业务。作为一个示例，为了使得宏基站和用户设备在不改变制式的情况下，WLAN AP可以接收到宏基站或用户设备发送的信号，可以在WLAN AP上安装有与宏基站具有相同制式的上行接收机，该上行接收机用于接收宏基站发送的信号或者接收用户设备发送的信号。2A is a schematic diagram of a heterogeneous network architecture provided by an embodiment of the present invention. In the heterogeneous network network, the first access device is a WLAN AP using the WLAN standard, the second access device is a macro base station, and the WLAN AP and The macro base station has different standards, and the user equipment can use the different standards to access the WLAN AP or the macro base station. In the heterogeneous network, the macro base station is the base station currently accessed by the user equipment, and the macro base station provides business services. When the user equipment moves within the signal coverage of the WLAN AP, if the load of the macro base station is heavy, at least one service bearer between the user equipment and the macro base station can be switched to the WLAN AP, thereby offloading the data in the macro base station business. As an example, in order to enable the WLAN AP to receive the signal sent by the macro base station or the user equipment without changing the standards of the macro base station and the user equipment, an uplink receiver with the same standard as the macro base station can be installed on the WLAN AP , the uplink receiver is configured to receive a signal sent by the macro base station or receive a signal sent by the user equipment.
基于图2A所示的异构网络的系统架构图，图2B是本发明实施例一方面提供的一种通信方法的示意性流程图，在该方法可以由WLAN AP执行。Based on the system architecture diagram of the heterogeneous network shown in FIG. 2A , FIG. 2B is a schematic flowchart of a communication method provided by an aspect of the embodiment of the present invention, where the method can be executed by a WLAN AP.
200，WLAN AP使用宏基站的下行频点接收宏基站广播的定时信息，并根据该定时信息，与第二接入设备进行系统帧同步。200. The WLAN AP uses the downlink frequency of the macro base station to receive timing information broadcast by the macro base station, and performs system frame synchronization with the second access device according to the timing information.
WLAN AP在与宏基站进行系统帧同步时，WLAN AP通过安装在该WLAN AP的与宏基站具有相同制式的上行接收机，接收宏基站广播的定时信息，从而WLAN AP可以使用该定时信息监听用户设备。可选的，该定时信息可以各个系统帧的帧号所对应的时间，也就是各个系统帧所对应的时间。本领域技术人员可以理解，WLAN在获取了该定时信息的情况下，可以通过定时信息进行与宏基站的系统帧同步。在WLAN AP与宏基站进行了系统帧同步的情况下，WLAN AP与由宏基站提供服务的用户设备之间也是进行系统帧同步的。换句话说，用户设备、WLAN AP和宏基站三者之间是进行系统帧同步的。在WLAN AP与宏基站进行了系统帧同步的情况下，WLANAP便可以通过与宏基站通过X2口或者私有接口进行交互，获取到该宏基站发送的该用户设备的时域位置信息，其中该时域位置信息可以是用户设备与系统帧的映射关系，具体地，该映射关系可以是用户设备与系统帧中子帧的映射关系。When the WLAN AP performs system frame synchronization with the macro base station, the WLAN AP receives the timing information broadcast by the macro base station through the uplink receiver installed on the WLAN AP and has the same standard as the macro base station, so that the WLAN AP can use the timing information to monitor the user equipment. Optionally, the timing information may be the time corresponding to the frame number of each system frame, that is, the time corresponding to each system frame. Those skilled in the art can understand that, after acquiring the timing information, the WLAN can perform system frame synchronization with the macro base station through the timing information. In the case that the WLAN AP and the macro base station have performed system frame synchronization, the WLAN AP and the user equipment served by the macro base station also perform system frame synchronization. In other words, system frames are synchronized among the user equipment, the WLAN AP and the macro base station. When the WLAN AP and the macro base station have synchronized the system frame, the WLAN AP can interact with the macro base station through the X2 port or the private interface to obtain the time domain location information of the user equipment sent by the macro base station, where the time The domain location information may be a mapping relationship between user equipment and a system frame, specifically, the mapping relationship may be a mapping relationship between user equipment and a subframe in a system frame.
具体地，通常情况下，在宏基站为用户设备提供服务的情况下，为保证宏基站和用户设备之间正常的数据业务，宏基站中保存着用户设备的时域位置信息。WLAN AP可以通过以下几种可能实现方式从宏基站中获取时域位置信息：WLAN AP可以向宏基站发送用于请求用户设备的时域位置信息的请求消息，以便宏基站在接收到该请求消息的情况下向第一接入设备发送用户设备的时域位置信息。或者，宏基站可以直接将时域位置信息广播给WLAN AP。Specifically, usually, when the macro base station provides services for the user equipment, in order to ensure normal data services between the macro base station and the user equipment, the macro base station stores time domain location information of the user equipment. The WLAN AP can obtain the time-domain location information from the macro base station in the following possible ways: the WLAN AP can send a request message for requesting the time-domain location information of the user equipment to the macro base station, so that the macro base station can receive the request message In the case of , the time-domain location information of the user equipment is sent to the first access device. Alternatively, the macro base station may directly broadcast the time domain location information to the WLAN AP.
可选地，作为一个实施例，宏基站与WLAN AP进行系统帧同步的过程可以是周期性执行的。WLAN AP可以每隔一段时间便从监听模式（即对用户设备进行监听）转换为同步模式（即从宏基站接收定时信息，进行与宏基站的系统帧同步），并在与宏基站进行同步之后再切换回监听模式。WLANAP周期性地从监听模式切换到同步模式，可以进行与第二接入设备在时间上系统帧持续地同步，从而WLAN AP可以根据用户设备的时域位置信息区确定用户设备。Optionally, as an embodiment, the process of performing system frame synchronization between the macro base station and the WLAN AP may be performed periodically. The WLAN AP can switch from listening mode (that is, monitoring user equipment) to synchronous mode (that is, receiving timing information from the macro base station and performing system frame synchronization with the macro base station) at regular intervals, and after synchronizing with the macro base station Then switch back to monitor mode. The WLAN AP periodically switches from the monitoring mode to the synchronous mode, and can continuously synchronize the system frame with the second access device in time, so that the WLAN AP can determine the user equipment according to the time domain location information area of the user equipment.
可选的，作为另一个实施例，该WLAN AP与宏基站进行系统帧同步的过程可以是在确定需要进行同步的情况下进行的。例如，WLAN AP没有监听到需要进行监听的用户设备，或者该WLAN AP没有监听到的需要进行监听的用户设备的数量与用户设备的总数比例大于预设阈值（即漏检率过高），则WLAN AP可以判断出可以与宏基站进行系统帧同步后再进行监听。用户设备可以在需要进行同步的情况下再进行同步，以进行与第二接入设备在时间上系统帧的同步。这样可以减少由于WLAN AP与宏基站进行同步导致的对用户设备监听的中断。Optionally, as another embodiment, the process of performing system frame synchronization between the WLAN AP and the macro base station may be performed when it is determined that synchronization is required. For example, if the WLAN AP does not hear the user equipment that needs to be monitored, or the ratio of the number of user equipment that does not need to be monitored by the WLAN AP to the total number of user equipment is greater than a preset threshold (that is, the missed detection rate is too high), then The WLAN AP can determine that the system frame synchronization with the macro base station can be performed before monitoring. The user equipment may re-synchronize if it needs to be synchronized, so as to synchronize the system frame with the second access device in terms of time. In this way, the interruption of listening to the user equipment caused by the synchronization between the WLAN AP and the macro base station can be reduced.
可选的，作为另一个实施例，该WLAN AP与宏基站进行系统帧同步过程还可以是在WLAN AP进行初始配置时执行的。在WLAN进行初始配置时，WLAN AP可以通过空口接收宏基站广播的工作参数，并根据该工作参数对WLAN AP进行配置以便可以从空口接收宏基站广播的定时信息等消息并对用户设备进行监听。该工作参数包括宏基站的PCI、小区带宽、PHICH配置信息、天线数目CP长度、随机接入码和时隙、工作制式和工作频点等，其中宏基站的PCI、小区带宽、PHICH配置信息、工作模式和工作频点用于WLAN AP通过空口从宏基站接收信息（例如宏基站广播的定时信息），随机接入码和时隙、工作模式和工作频点用于WLANAP接收用户设备发送的上行信号。该工作参数还可以包括定时信息，以便WLAN AP在初始配置时与宏基站在时间上进行系统帧的同步。或者，如果该工作参数不包括定时信息，则该WLAN AP可以在根据该工作参数进行配置之后与第二接入设备进行同步，以便与第二接入设备进行系统帧同步，然后对用户设备进行监听。由于WLAN AP在初始配置时与第二接入设备进行系统帧同步，这样第一接入设备就可以根据用户设备的时域位置信息确定用户设备。Optionally, as another embodiment, the system frame synchronization process between the WLAN AP and the macro base station may also be performed when the WLAN AP performs initial configuration. When the WLAN is initially configured, the WLAN AP can receive the working parameters broadcast by the macro base station through the air interface, and configure the WLAN AP according to the working parameters so that it can receive messages such as timing information broadcast by the macro base station from the air interface and monitor the user equipment. The working parameters include the PCI of the macro base station, cell bandwidth, PHICH configuration information, number of antennas and CP length, random access code and time slot, working system and operating frequency, etc., among which the PCI of the macro base station, cell bandwidth, PHICH configuration information, The working mode and working frequency are used for WLAN AP to receive information from the macro base station through the air interface (such as the timing information broadcast by the macro base station), and the random access code and time slot, working mode and working frequency are used for WLAN AP to receive the uplink sent by the user equipment Signal. The working parameters may also include timing information, so that the WLAN AP and the macro base station can synchronize system frames in time during initial configuration. Alternatively, if the working parameter does not include timing information, the WLAN AP may perform synchronization with the second access device after being configured according to the working parameter, so as to perform system frame synchronization with the second access device, and then synchronize the user equipment monitor. Since the WLAN AP performs system frame synchronization with the second access device during initial configuration, the first access device can determine the user equipment according to the time domain location information of the user equipment.
可以理解的是，上述三种情况中的任意两种可以相互结合，或者三种情况同时结合。例如，WLAN AP可以在初始配置时与宏基站进行系统帧同步，还可以在需要进行系统帧同步的情况下与宏基站进行系统帧同步。再如，WLAN AP在周期性与宏基站进行系统帧同步的情况下，还可以在需要进行系统帧同步的情况下与宏基站进行系统帧同步。又如，WLANAP可以在初始配置时与宏基站进行系统帧同步，还可以周期性与宏基站进行系统帧同步，并在需要进行系统帧同步的情况下与宏基站进行系统帧同步。It can be understood that any two of the above three situations may be combined with each other, or the three situations may be combined at the same time. For example, the WLAN AP can perform system frame synchronization with the macro base station during initial configuration, and can also perform system frame synchronization with the macro base station when system frame synchronization is required. For another example, when the WLAN AP periodically performs system frame synchronization with the macro base station, it may also perform system frame synchronization with the macro base station when system frame synchronization is required. For another example, the WLAN AP can perform system frame synchronization with the macro base station during initial configuration, and can also perform system frame synchronization with the macro base station periodically, and perform system frame synchronization with the macro base station when system frame synchronization is required.
201，WLAN AP获取用户设备的时域位置信息。可选的，该时域位置信息包括用户设备与系统帧的映射关系，具体地，该映射关系可以为用户设备与系统帧中子帧的映射关系。201. The WLAN AP acquires time-domain location information of the user equipment. Optionally, the time-domain location information includes a mapping relationship between the user equipment and a system frame, specifically, the mapping relationship may be a mapping relationship between the user equipment and a subframe in the system frame.
可选地，WLAN AP可以通过X2口或私有接口从宏基站接收时域位置信息，也可以通过空口接收宏基站广播的时域位置信息。Optionally, the WLAN AP can receive the time-domain location information from the macro base station through the X2 interface or a private interface, and can also receive the time-domain location information broadcast by the macro base station through the air interface.
202，WLAN AP对用户设备进行监听。202. The WLAN AP monitors the user equipment.
可选的，在宏基站的工作模式为FDD的情况下，在对用户设备进行监听之前，该WLAN AP可以将工作频点由宏基站的下行频点切换为用户设备的上行频点，以便对用户设备进行监听。Optionally, when the working mode of the macro base station is FDD, before monitoring the user equipment, the WLAN AP may switch the working frequency from the downlink frequency of the macro base station to the uplink frequency of the user equipment, so as to The user equipment monitors.
本领域技术人员可以理解，201和202并无时间顺序关系。Those skilled in the art can understand that 201 and 202 have no time sequence relationship.
203，WLAN AP在对用户设备进行监听的过程中，WLAN AP根据用户设备的时域位置信息，确定用户设备具体为哪个用户设备。203. During the process of monitoring the user equipment by the WLAN AP, the WLAN AP determines which user equipment the user equipment is according to the time-domain location information of the user equipment.
在用户设备、WLAN AP与宏基站进行系统帧同步的情况下，WLAN AP可以根据监听到的上行信号的时域位置确定发送该上行信号的用户设备。具体地，在用户设备、宏基站与WLAN AP三者进行系统帧同步时，在同一时间三者的系统帧号也是相同的。在此情况下，如果WLAN AP在时间t时监听到某一个用户设备发送的上行信号，则该WLAN AP可以确定对应于时间t的系统帧并根据系统帧与用户设备的映射关系，识别出使用该系统帧的用户设备具体为哪一个用户设备。When the user equipment, the WLAN AP and the macro base station perform system frame synchronization, the WLAN AP can determine the user equipment sending the uplink signal according to the time domain position of the monitored uplink signal. Specifically, when the user equipment, the macro base station, and the WLAN AP perform system frame synchronization, the system frame numbers of the three are also the same at the same time. In this case, if the WLAN AP listens to an uplink signal sent by a certain user equipment at time t, the WLAN AP can determine the system frame corresponding to time t and identify the user equipment according to the mapping relationship between the system frame and the user equipment. Which specific user equipment is the user equipment of the system frame.
进一步地，WLAN AP可以根据识别出用户设备的上行信号计算出对应于该上行信号的接收功率，并从宏基站接收用于指示该识别出的用户设备的上行信号的发射功率的信息。WLAN AP可以根据该接收功率和该发射功率计算出该用户设备到该WLAN AP的路损，并根据该路损判断该用户设备是否在该WLAN AP的覆盖范围内。如果该用户设备在该WLAN AP的覆盖范围内，则可以请求宏基站将该用户设备的至少一个业务承载切换到WLANAP中，并在宏基站响应该请求后，将该用户设备与该宏基站之间的至少一个业务承载切换到该WLANAP中，从而实现业务流量的分流。Further, the WLAN AP may calculate the received power corresponding to the uplink signal according to the uplink signal of the identified user equipment, and receive information indicating the transmit power of the uplink signal of the identified user equipment from the macro base station. The WLAN AP can calculate the path loss from the user equipment to the WLAN AP according to the received power and the transmit power, and judge whether the user equipment is within the coverage of the WLAN AP according to the path loss. If the user equipment is within the coverage of the WLAN AP, it may request the macro base station to switch at least one service bearer of the user equipment to the WLAN AP, and after the macro base station responds to the request, the user equipment and the macro base station At least one service bearer in the network is switched to the WLANAP, so as to realize the offloading of service traffic.
本实施例仅以LTE系统中，第一接入设备为WLAN AP，第二接入设备为宏基站为例，本实施例并不仅仅限于此：WLAN AP可以替换为GSM系统或CDMA系统中的BTS，WCDMA系统中的NodeB等各种可以具有业务分流功能的接入节点；宏基站可以为LTE系统中的eNB或e-NodeB，也可以为GSM或CDMA中的BTS，或者WCDMA中的NodeB等。This embodiment only takes the LTE system in which the first access device is a WLAN AP and the second access device is a macro base station as an example. This embodiment is not limited to this: the WLAN AP can be replaced by a GSM system or a CDMA system. BTS, NodeB in WCDMA system and other access nodes that can have service distribution function; macro base station can be eNB or e-NodeB in LTE system, or BTS in GSM or CDMA, or NodeB in WCDMA, etc. .
应用本发明实施例提供的技术方案，第一接入设备通过接收第二接入设备广播的定时信息，第一接入设备与第二接入设备进行系统帧同步，使得第一接入设备与接入到第二接入设备的用户设备也进行了系统帧同步。第一接入设备根据从第二接入设备接收到的该用户设备时域位置信息，从该时域位置信息中识别出当前发送上行信号的具体用户设备。与现有技术相比，由于经过系统帧同步后使用用户设备的时域位置信息对用户设备进行识别具有较高的时间精度，可以更加准确的识别出用户设备。Applying the technical solution provided by the embodiment of the present invention, the first access device performs system frame synchronization with the second access device by receiving the timing information broadcast by the second access device, so that the first access device and the second access device The user equipment connected to the second access device also performs system frame synchronization. According to the time-domain location information of the user equipment received from the second access device, the first access device identifies the specific user equipment currently sending the uplink signal from the time-domain location information. Compared with the prior art, since the time domain position information of the user equipment is used to identify the user equipment after system frame synchronization has higher time precision, the user equipment can be identified more accurately.
