Description

Group call creation and group call data transmission method, mobility management device and base station

Technical field

The present invention relates to the field of trunking communication technologies, and in particular, to a group call creation and group call data transmission method, a mobility management apparatus, and a base station.

Background technique

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.

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.

detailed description

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.

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

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.

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. Receive a group call creation instruction, and parse the configuration information of the group call to be created from the group call creation instruction.

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. Analyze, according to the configuration information of the group call to be created, the base station included in the group call to be created.

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. 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.

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.

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. 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.

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.

Optionally, in another embodiment of the present invention, the setting, according to the selected set number of the wireless network temporary identifiers, the group wireless network temporary identifiers for the group call to be created, including:

Specifically, the mobility management device MME has selected a set number of radio network temporary identifiers from all the assignable radio network temporary identifiers for group call communication before the group call is created, and correspondingly, the base station side also reserves corresponding A set number of wireless network temporary identifiers are used for group call communication. When the MME creates a group call, it selects an unoccupied wireless network temporary identifier from the preset number of wireless network temporary identifiers that are selected in advance, and sets the temporary wireless network temporary identifier of the group call to be created. . The unoccupied wireless network temporary identifier refers to a wireless network temporary identifier that is not allocated to other group calls as a temporary identifier of the group wireless network.

Specifically, for the specific working content of the processor 302 in this embodiment, refer to the content of the corresponding method embodiment, and details are not described herein again.

Optionally, in another embodiment of the present invention, the processor 302 selects, from among all the assignable wireless network temporary identifiers, a set number of radio network temporary identifiers for group call communication, specifically for:

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.

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.

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.

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:

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. Send the downlink group call data after the scrambling process to the user end of the group call.

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.

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.
