All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As can be seen from the background art, in the process of implementing the hang-up of the LTE group call trunking service, the base station needs to notify the terminal to delete the group call resource and stop the periodic trunking paging, but in a normal situation, since the group call release message and the trunking paging message sent by the base station are transmitted on different transmission channels, a situation may occur in which the base station sends the group call release message and the terminal receives the trunking paging message again, so that the terminal is called again without exiting the group call service. When the terminal cannot be hung up, the upper-layer application of the terminal may be abnormal. Therefore, the application discloses a method and a system for hanging up an LTE group call trunking service, which can ensure that a terminal exits from the group call service, avoid the problem that the terminal is called again, avoid the abnormal upper application of the terminal, and improve the use experience of a user and the reliability of equipment.
As shown in fig. 1, a schematic flow diagram of a method for hanging up an LTE group call trunking service disclosed in an embodiment of the present application includes:
s101: when the terminal hangs up the group calling cluster service, the base station sends a group calling release message and a cluster paging message to the terminal.
In S101, the cluster paging message includes an extension field. The extension field is generated in advance by the base station, and the extension field is a field carrying a release indication. The release indication is determined by the base station and the terminal negotiation.
Alternatively, the base station and the terminal may negotiate the determined release indication by using various content representations. For example: the release indication may indicate the content of the release indication by using a preset release character string (e.g., release, 0001, etc.). And writing the determined release indication into an extension field in the trunking paging message, so that the trunking paging message contains the extension field of the release indication. In a specific implementation, if the extended field of the trunking paging message is analyzed to contain the content of the release indication represented by the preset release character string, the terminal determines to execute the exit from the group call service.
S102: and when the terminal receives any one of the group call release message and the trunking paging message, exiting the group call service.
In the specific implementation process, the group call release message and the trunking paging message that are simultaneously sent may not be simultaneously received by the terminal due to various reasons in the message transmission process. Based on the possible situation in the LTE group call trunking service hang-up scenario, the embodiment of the present application is further described.
As shown in fig. 2, a schematic flow diagram for hanging up an LTE group call trunking service provided in an embodiment of the present application includes the following steps:
s201: and the base station simultaneously transmits the group call release message and the trunking paging message to the terminal.
The structure of the trunking paging message in S201 is the same as that of the trunking paging message mentioned in S101 shown in fig. 1, and may be referred to here, which is not described again.
S202: and the terminal receives the group call release message, deletes the corresponding group call resource based on the group call release message and exits the group call service.
S203: and the terminal receives the trunking paging message and does not execute any operation.
In the process of implementing S203, the terminal parses out the content that the extension field of the trunking paging message contains the preset release character string to represent the release indication, and after exiting the group call service, the terminal is not called again.
In the embodiment of the application, when the terminal hangs up the group call trunking service, the base station sends a group call release message and a trunking paging message to the terminal, and after the terminal receives the group call release message, the terminal deletes the corresponding group call resource. When the content of the release indication represented by the preset release character string contained in the analyzed extension field of the trunking paging message is analyzed, the problem that the terminal is called again after the terminal exits the group calling service can be guaranteed based on the extension field with the release indication contained in the trunking paging message, and the upper application exception of the terminal is avoided, so that the use experience of a user and the reliability of equipment are improved.
As shown in fig. 3, a schematic flow diagram of another LTE group call trunking service hangup provided in the embodiment of the present application includes the following steps:
s301: when the terminal hangs up the group calling cluster service, the base station sends a group calling release message and a cluster paging message to the terminal.
The structure of the trunking paging message in S301 is the same as that of the trunking paging message mentioned in S101 shown in fig. 1, and may be referred to here, which is not described again.
S302: and when the terminal receives the trunking paging message, determining that the extension field carried by the trunking paging message contains a release instruction, deleting the corresponding group calling resource based on the release instruction, and exiting the group calling service.
In the specific implementation process of S302, the terminal parses out the content that the extension field of the trunking paging message contains the preset release character string indicating the release instruction, and executes the operation of exiting the group call service.
S303: and the terminal receives the group call release message and does not execute any operation.
In the process of implementing S303, since the terminal already exits the group call service in the foregoing executing S302, the terminal does not perform any operation after receiving the group call release message.
In the embodiment of the application, when the terminal hangs up the group call trunking service, the base station sends the group call release message and the trunking paging message to the terminal, and if the terminal receives the trunking paging message first, the extension field of the trunking paging message is analyzed to contain the content of the release indication represented by the preset release character string. The terminal deletes the corresponding group call resource and does not execute any operation after receiving the group call release message subsequently. The LTE group call trunking service hanging-up method disclosed by the embodiment of the application can ensure that the problem that the terminal is called up again after the terminal exits the group call service based on the extension field with the release indication contained in the trunking paging message, and avoids abnormal application of the upper layer of the terminal, thereby improving the use experience of users and the reliability of equipment.
