在集群通信过程中,基站使用组无线网络临时标识对组呼小区的组呼数据进行加扰处理。其中,基站的组无线网络临时标识由基站决定,各个基站的组无线网络临时标识各不相同。因此,当一个集群组呼覆盖多个基站的多个小区时,不同基站下的组呼小区的组无线网络临时标识各不相同。During the trunking communication process, the base station performs scrambling processing on the group call data of the group call cell by using the group radio network temporary identifier. The group radio network temporary identifier of the base station is determined by the base station, and the group radio network temporary identifiers of the respective base stations are different. Therefore, when a cluster group calls multiple cells of multiple base stations, the group radio network temporary identifiers of the group call cells under different base stations are different.
集群终端在某一组呼小区内接收到组呼数据时,需要通过该组呼小区的组无线网络临时标识对接收到的组呼数据进行解析。位于某一基站下的组呼小区的空闲状态的集群终端移动进入另一个基站下的组呼小区,并且接收组呼数据时,该集群终端需要等待并监听当前所在小区的组寻呼消息,从监听的组寻呼消息中获取到当前所在小区的组无线网路临时标识,然后再对接收的组呼数据进行解析。在上述解析组呼数据的过程中,空闲状态的集群终端在跨越组呼小区接收到组呼数据时,需要等待并监听当前所在小区的群组寻呼消息,获取到当前所在小区的组无线网络临时标识后,才能对接收的组呼数据进行解析,其过程繁琐,解析效率低。When the cluster terminal receives the group call data in a certain group of call cells, it needs to parse the received group call data through the group radio network temporary identifier of the group call cell. When the cluster terminal in the idle state of the group call cell located under a certain base station moves into the group call cell under another base station, and receives the group call data, the cluster terminal needs to wait and listen to the group paging message of the current cell. The monitored group paging message obtains the group wireless network temporary identifier of the current cell, and then parses the received group call data. In the process of parsing the group call data, when the cluster terminal in the idle state receives the group call data across the group call cell, it needs to wait for and listen to the group paging message of the current cell, and obtain the group wireless network of the current cell. After the temporary identification, the received group call data can be parsed. The process is cumbersome and the resolution efficiency is low.

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
本发明实施例公开了一种组呼创建方法,应用于移动性管理装置,所述移动性管理装置从所有可分配的无线网络临时标识中,选择设定数量的无线网络临时标识用于组呼通信;The embodiment of the invention discloses a group call creation method, which is applied to a mobility management device, and the mobility management device selects a set number of wireless network temporary identifiers for group call from all assignable wireless network temporary identifiers. Communication
具体的,移动性管理装置(Mobility Management Entity,MME)为通信系统中的高层部分,是通信系统接入网络的关键控制节点。移动性管理装置主要负责移动性管理、承载管理、用户鉴权认证等处理工作。在LTE通信系统中,MME为各个基站分配无线网络临时标识,各个基站根据MME分配的无线网络临时标识对通信数据进行加扰处理。在集群通信模式中,MME向基站下发组呼创建指令,控制基站建立组呼。在本发明实施例技术方案中,MME在为基站分配无线网络临时标识时,预留部分无线网络临时标识不做分配,而是用于组呼通信。相应的,在基站侧,这些预留的无线网络临时标识没有用于进行LTE通信加扰,而是用于在组呼通信时,对组呼数据的加扰。Specifically, the Mobility Management Entity (MME) is a high-level part of the communication system and is a key control node for the communication system to access the network. The mobility management device is mainly responsible for processing such as mobility management, bearer management, and user authentication. In the LTE communication system, the MME allocates a radio network temporary identifier to each base station, and each base station performs scrambling processing on the communication data according to the radio network temporary identifier allocated by the MME. In the trunking communication mode, the MME sends a group call creation command to the base station to control the base station to establish a group call. In the technical solution of the embodiment of the present invention, when the MME allocates a temporary identifier of the wireless network, the MME reserves a part of the temporary identifier of the wireless network, but does not allocate, but is used for group call communication. Correspondingly, on the base station side, these reserved wireless network temporary identifiers are not used for LTE communication scrambling, but are used for scrambling group call data during group call communication.
移动性管理装置MME完成上述处理工作后,在进行组呼创建时,参见图1所示,具体创建方法如下:After the mobility management device MME completes the foregoing processing, when creating a group call, refer to FIG. 1 , and the specific creation method is as follows:
S101、接收组呼创建指令,并从所述组呼创建指令中解析得到待创建的组呼的配置信息;S101. Receive a group call creation instruction, and parse the configuration information of the group call to be created from the group call creation instruction.
具体的,在实际通信应用场景中,需要创建组呼通信时,技术人员向移动性管理装置MME输入组呼创建指令,该指令中包括待创建的组呼的配置信息,例如组呼覆盖范围、组呼带宽等配置信息。MME在接收到组呼创建指令
后,自动对指令进行解析,从中解析出待创建的组呼的配置信息。Specifically, in the actual communication application scenario, when the group call communication needs to be created, the technician inputs a group call creation instruction to the mobility management device MME, where the command includes the configuration information of the group call to be created, for example, the group call coverage range, Configuration information such as group call bandwidth. The MME receives the group call creation command.
After that, the command is automatically parsed, and the configuration information of the group call to be created is parsed therefrom.
S102、根据所述待创建的组呼的配置信息,分析得到所述待创建的组呼所包括的基站;S102. Analyze, according to the configuration information of the group call to be created, the base station included in the group call to be created.
具体的,MME创建组呼时,需要向组呼覆盖的基站发送组呼创建指令,控制基站创建组呼。因此,MME在从接收的组呼创建指令中解析得到待创建的组呼的配置信息后,进一步从待创建的组呼的配置信息中分析得到该组呼所覆盖的范围,以及该组呼所包括的基站,以便于MME向这些基站发送组呼创建指令。Specifically, when the MME creates a group call, it needs to send a group call creation command to the base station covered by the group call, and control the base station to create a group call. Therefore, after parsing the configuration information of the group call to be created from the received group call creation command, the MME further analyzes the range covered by the group call from the configuration information of the group call to be created, and the group call group. The base stations are included so that the MME sends a group call creation instruction to the base stations.
S103、根据选择的设定数量的无线网络临时标识,为所述待创建的组呼设置组无线网络临时标识;S103. Set a group radio network temporary identifier for the group call to be created according to the selected set number of radio network temporary identifiers.
具体的,在现有技术中,MME在接收到组呼创建指令后,直接将组呼配置信息发送给相应的基站,并不对组呼的组无线网络临时标识进行设置。各个基站创建组呼后,各自决定用于组呼通信的组无线网络临时标识,因此导致同一组呼的不同基站小区的组无线网络临时标识不同。Specifically, in the prior art, after receiving the group call creation command, the MME directly sends the group call configuration information to the corresponding base station, and does not set the group radio network temporary identifier of the group call. After each group establishes a group call, each group determines a group radio network temporary identifier used for group call communication, and thus the group radio network temporary identifiers of different base station cells of the same group call are different.
而在本发明实施例技术方案中,MME已事先从所有可分配的无线网络临时标识中选择设定数量的无线网络临时标识用于组呼通信。在MME向基站发送组呼创建指令前,先根据事先选择出的无线网络临时标识,为待创建的组呼设置组无线网络临时标识。也就是说,MME创建组呼时,为组呼设置唯一确定的组无线网络临时标识。In the technical solution of the embodiment of the present invention, the MME has previously selected a set number of wireless network temporary identifiers from all the assignable wireless network temporary identifiers for group call communication. Before the MME sends the group call creation command to the base station, the group wireless network temporary identifier is set for the group call to be created according to the previously selected wireless network temporary identifier. That is to say, when the MME creates a group call, it sets a uniquely determined group radio network temporary identifier for the group call.
S104、将所述待创建的组呼的配置信息,以及所述组无线网络临时标识信息,发送给所述待创建的组呼所包括的基站,使所述待创建的组呼所包括的基站根据所述待创建的组呼的配置信息创建组呼,以及根据所述组无线网络临时标识对传输的所述组呼的组呼数据进行加扰处理。S104. The configuration information of the group call to be created, and the group radio network temporary identifier information are sent to the base station included in the group call to be created, so that the base station included in the group call to be created is included. And generating a group call according to the configuration information of the group call to be created, and performing scrambling processing on the group call data of the group call that is transmitted according to the group wireless network temporary identifier.
具体的,MME为组呼设置组无线网络临时标识后,将组无线网络临时标识信息随组呼配置信息下发给该组呼所包括的各个基站。各个基站接收到组呼配置信息后,根据组呼配置信息创建组呼,并且根据接收的组无线网络临时标识信息,使用自身的,对应该组无线网络临时标识的无线网络临时标识对该组
呼的组呼数据进行加扰处理。由于各个基站接收的组无线网络临时标识信息是相同的,因此该组呼的各个基站对组呼数据进行加扰使用的是相同的无线网络临时标识。处于该组呼的集群终端在该组呼的任意一个基站小区,使用相同的组无线网络临时标识,即可完成对接收的组呼数据的解析处理。Specifically, after the MME sets the group radio network temporary identifier for the group call, the group radio network temporary identifier information is sent to each base station included in the group call with the group call configuration information. After receiving the group call configuration information, each base station creates a group call according to the group call configuration information, and uses its own wireless network temporary identifier corresponding to the group wireless network temporary identifier according to the received group wireless network temporary identifier information.
The group call data of the call is scrambled. Since the group radio network temporary identification information received by each base station is the same, each base station of the group call scrambles the group call data using the same radio network temporary identifier. The cluster terminal in the group call can perform the parsing process of the received group call data by using the same group radio network temporary identifier in any one of the base station cells of the group call.

从分配给基站占用的无线网络临时标识中,选择设定数量的无线网络临时标识用于组呼通信。From the wireless network temporary identifier allocated to the base station occupation, a set number of wireless network temporary identifiers are selected for group call communication.
具体的,对于每个基站,都需要占用一些无线网络临时标识(Radio Network Temporary Identifier,RNTI),例如MME设定基站占用RNTI1-30,则表示RNTI1-RNTI30被分配给基站使用。进一步的,MME可以将RNTI1-30中的RNTI1-10设定为用于组呼通信的组无线网络临时标识,相当于为基站统一了组无线网络临时标识。Specifically, for each base station, a Radio Network Temporary Identifier (RNTI) needs to be occupied. For example, if the MME sets the base station occupation RNTI1-30, it indicates that the RNTI1-RNTI 30 is allocated to the base station for use. Further, the MME may set the RNTI 1-10 in the RNTI 1-30 as a group radio network temporary identifier used for group call communication, which is equivalent to unifying the group radio network temporary identifier for the base station.
本发明实施例公开了一种组呼数据传输方法,应用于基站,所述基站接收移动性管理装置发送的待创建的组呼的配置信息和所述待创建的组呼的组无线网络临时标识信息;根据所述待创建的组呼的配置信息创建组呼;保存所述待创建的组呼的组无线网络临时标识信息,并周期性地在创建的组呼的小区中广播包含所述组呼的组无线网络临时标识的信息;The embodiment of the present invention discloses a group call data transmission method, which is applied to a base station, where the base station receives configuration information of a group call to be created sent by the mobility management device, and a group wireless network temporary identifier of the group call to be created. Creating a group call according to the configuration information of the group call to be created; storing the group wireless network temporary identification information of the group call to be created, and periodically broadcasting the group in the created group call cell Information about the temporary identification of the wireless network of the group;
具体的,在本发明实施例技术方案中,移动性管理装置(Mobility Management Entity,MME)从所有可分配的无线网络临时标识中,选择设定数量的无线网络临时标识用于组呼通信,相应的在基站侧,基站将MME选择的这些无线网络临时标识预留给组呼通信使用。具体在创建组呼时,MME将组呼配置信息和用于该组呼的组无线网络临时标识信息,发送给基站。基站根据接收的组呼配置信息创建组呼,并保存该组呼的组无线网络临时标识信息。在组呼创建后,基站周期性地在组呼小区中广播该组呼的组无线网络临时标识信息。Specifically, in the technical solution of the embodiment of the present invention, the Mobility Management Entity (MME) selects a set number of radio network temporary identifiers for group call communication from all assignable wireless network temporary identifiers, correspondingly On the base station side, the base station reserves the radio network temporary identifiers selected by the MME for group call communication use. Specifically, when the group call is created, the MME sends the group call configuration information and the group radio network temporary identifier information for the group call to the base station. The base station creates a group call according to the received group call configuration information, and saves the group wireless network temporary identifier information of the group call. After the group call is created, the base station periodically broadcasts the group radio network temporary identifier information of the group call in the group call cell.
基站按照上述过程创建组呼后,进行组呼数据传输时,参见图4所示,其
具体传输过程如下:After the base station creates a group call according to the above process, and performs group call data transmission, as shown in FIG. 4,
The specific transmission process is as follows:
S401、接收创建的组呼的下行组呼数据;S401. Receive downlink group call data of the created group call.
具体的,基站从高层核心网接收需要下发至创建的该组呼的组呼数据。Specifically, the base station receives the group call data that needs to be delivered to the created group call from the high-layer core network.
S402、根据保存的所述组呼的组无线网络临时标识,对所述下行组呼数据进行加扰处理;S402: Perform scrambling processing on the downlink group call data according to the saved group radio network temporary identifier of the group call.
具体的,基站在接收到下行组呼数据后,需要对下行组呼数据进行加扰处理。基站事先已保存MME发送的该组呼的组无线网络临时标识信息,根据该组无线网络临时标识信息,基站能够确认MME规定使用哪个预留的无线网络临时标识对该组呼的组呼数据进行加扰处理。具体的,由于MME设置的组无线网络临时标识是从事先选择的用于组呼通信的无线网络临时标识中选择的,因此组无线网络临时标识实际上就是对应着预留的用于组呼通信的无线网络临时标识中的某一个无线网络临时标识。基于上述原理,基站根据MME发送的组无线网络临时标识信息,能够快速确认应该使用哪个无线网络临时标识对组呼数据进行加扰处理。基站使用确认的无线网络临时标识对接收的组呼数据进行加扰处理即可。Specifically, after receiving the downlink group call data, the base station needs to perform scrambling processing on the downlink group call data. The base station has previously saved the group radio network temporary identifier information of the group call sent by the MME, and according to the group radio network temporary identifier information, the base station can confirm which reserved radio network temporary identifier used by the MME to perform the group call data of the group call. Scrambling processing. Specifically, since the group radio network temporary identifier set by the MME is selected from a pre-selected radio network temporary identifier for group call communication, the group radio network temporary identifier is actually corresponding to the reserved group call communication. One of the wireless network temporary identifiers in the wireless network temporary identifier. Based on the above principle, the base station can quickly confirm which radio network temporary identifier should be used to perform scrambling processing on the group call data according to the group radio network temporary identifier information sent by the MME. The base station may perform scrambling processing on the received group call data by using the confirmed wireless network temporary identifier.
S403、将加扰处理后的所述下行组呼数据发送给所述组呼的用户端。S403. Send the downlink group call data after the scrambling process to the user end of the group call.
具体的,基站在对组呼数据进行加扰处理后,通过组呼小区发送给组呼用户端。由于基站一直在周期性地广播组无线网络临时标识信息,因此,组呼用户端在接收到组呼数据之前,已经获取到该组呼的组无线网络临时标识,使用获取的组无线网络临时标识,用户端能够快速完成对接收的组呼数据的解析,而不必在解析组呼数据之前先等待接收该组呼小区的组无线网络临时标识信息。而且,当用户端跨小区接收组呼数据时,不必更换组无线网络临时标识,使用先前使用的组无线网络临时标识就可以完成数据解析。Specifically, after performing the scrambling process on the group call data, the base station sends the group call cell to the group call client. Since the base station has been periodically broadcasting the temporary identification information of the group wireless network, the group call client has obtained the group wireless network temporary identifier of the group call before receiving the group call data, and uses the obtained group wireless network temporary identifier. The UE can quickly complete the parsing of the received group call data without waiting to receive the group radio network temporary identifier information of the group call cell before parsing the group call data. Moreover, when the UE receives the group call data across the cell, it is not necessary to replace the group radio network temporary identifier, and the data parsing can be completed by using the previously used group radio network temporary identifier.
本发明实施例提出的数据传输方法,应用于基站,基站在创建组呼时,同时接收MME发送的该组呼的组无线网络临时标识信息。当基站传输下行组呼数据时,使用MME发送的组无线网络临时标识信息对应的无线网络临时标识对下行组呼数据进行加扰处理。由于创建该组呼的基站都按照MME发送的组无线网络临时标识对组呼数据进行加扰处理,因此,用户端在对组呼数据进行解析时,使用任一基站小区的组无线网络临时标识,都可以完成数据解析,尤其在跨小区接收组呼数据时,不必等待接收组无线网络临时标识,使用先前使
用的组无线网络临时标识就可以完成对组呼数据的解析。解析速度更快,效率更高。The data transmission method of the embodiment of the present invention is applied to a base station, and when the base station creates a group call, the base station simultaneously receives the group radio network temporary identification information of the group call sent by the MME. When the base station transmits the downlink group call data, the downlink group call data is scrambled by using the wireless network temporary identifier corresponding to the group radio network temporary identifier information sent by the MME. The base station that creates the group call performs scrambling processing on the group call data according to the group radio network temporary identifier sent by the MME. Therefore, when parsing the group call data, the UE uses the group radio network temporary identifier of any base station cell. , can complete the data parsing, especially when receiving the group call data across the cell, without waiting for the receiving group wireless network temporary identification, using the previous
The group wireless network temporary identifier used can complete the analysis of the group call data. The resolution is faster and more efficient.

周期性地在所述组呼的小区中广播所述群组寻呼消息。The group paging message is periodically broadcast in the cell of the group call.
具体的,基站在广播组无线网络临时标识信息时,有多种可选的方式。可以单独发送,也可以附加在其它信息中发送,本发明实施例不对基站广播的具体方式进行严格限定。常用的方式是,基站根据组呼的组无线网络临时标识,生成群组寻呼消息,周期性地在组呼小区中广播该群组寻呼消息。用户端在接收到该群组寻呼消息后,从该群组寻呼消息中能够解析得到该组无线网络临时标识。Specifically, when the base station broadcasts the temporary information of the wireless network of the group, there are various options. The specific manner of broadcasting the base station is not strictly limited in the embodiment of the present invention. In a common manner, the base station generates a group paging message according to the group radio network temporary identifier of the group call, and periodically broadcasts the group paging message in the group call cell. After receiving the group paging message, the UE can parse the group of wireless network temporary identifiers from the group paging message.
