Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
The group notification method provided by the invention is applied to an LTE broadband trunking system, and the system comprises user equipment, an MCPTT server and a group management server. Wherein the content of the first and second substances,
the user equipment is an MCPTT equipment which can be accessed to a plurality of group calls simultaneously and can be a handheld terminal, a vehicle-mounted station, a fixed station or a wireless dispatching station. It is noted that the user equipment establishes a connection with the MCPTT server through a broadband wireless access system, which includes a plurality of evolved base stations (enodebs) and the like that establish a trunked traffic session radio bearer. Since the group notification method provided in this embodiment is mainly directed to the interaction between the ue and the MCPTT server, the technical principle of the base station for establishing a radio bearer is not specifically limited in this embodiment, and is the same as that of the existing radio access system.
The MCPTT server is network side system equipment and is used for managing and controlling system cluster services, including establishment, maintenance and release of the cluster services, forwarding of cluster service data, notification of cluster service information change and the like, and is also responsible for completing cluster service talk right management and scheduling, management of cluster single call/group call and the like.
The group management server is used for storing the subscription information of the user equipment. Different user equipment can sign different groups, and the group management server establishes group information for different groups, wherein the group information comprises information such as group identification, identification of the user equipment signing the group and the like. For example, the group a includes subscribers 1, 2, 3, and 4, and the group information of the group a includes an identifier of the group a and identifiers of user devices corresponding to the subscribers 1, 2, 3, and 4 in the group a.
Under the above system architecture, the technical solution of the present invention is described in detail below with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic flowchart of an embodiment of a group notification method provided by the present invention, and as shown in fig. 1, the method includes the following specific implementation steps:
s11, the MCPTT server establishes a group call of the first group, and the group members accessing the group call are part of the group members in the first group.
S12, when the group call is changed, the MCPTT server sends a group change notification message to the ue corresponding to all the group members in the first group.
In S11, the MCPTT server obtains group user information of the first group to be established by querying the group list information of the group management server, and sends an establishment request to the user equipments corresponding to all group members of the first group;
the MCPTT server establishes a group call of the first group according to the acquired feedback information of the establishment request sent by each user equipment, and simultaneously sets the group state of the first group to be an activated state. Wherein the content of the first and second substances,
the group members accessing the group call of the first group are part of or all of the group members in the first group. In a possible case, if all the group members in the first group do not access the group call, the MCPTT server sets the group state of the first group to an inactive state, indicating that the group call establishment fails. The group members in the first group are all in a non-idle state at the same time, the non-idle state means that the number of group calls accessed by the user equipment at the same time reaches a preset maximum value, and in the non-idle state, the user equipment can directly refuse the group call establishment request or selectively release other accessed group calls according to a strategy and selectively access a new group call.
In S12, when the group call of the first group is changed, the MCPTT server transmits group change notification information to the user equipments corresponding to all the group members in the first group. Wherein the content of the first and second substances,
the group change notification information includes at least one of state change information, call type change information, and call priority change information of the group call.
There are two information formats for the group change notification information, TBCP format or SIP format.
When the group call of the first group in the activated state is finished, the MCPTT server sends state change information of the group call to the user equipment corresponding to all the group members in the first group, wherein the state change information is used for indicating that the group state of the first group is changed from the activated state to the inactivated state.
The call types for the group call include emergency calls, broadcast calls, pre-calls, etc. When the group call type of the first group in the activated state is changed, the MCPTT server sends the state change information of the group call to the user equipment corresponding to all the group members in the first group.
The group call generally performs a call service according to a preset call priority, and when the call priority of the first group in an activated state changes, the MCPTT server sends call priority change information of the group call to user equipment corresponding to all group members in the first group.
As will be understood by those skilled in the art, the group change notification message sent by the MCPTT server is used to notify all subscribers accessing and not accessing the group call of the update information of the group call, so that the subscriber not accessing the group call accesses the group call later through the group change notification message. However, in the prior art, when the group call of the first group in the active state is ended, or the group call type is changed, or the call priority is changed, the MCPTT server sends the group change notification message only to the user equipment accessing the group call, that is, the user equipment corresponding to a part of group members in the first group. A user not accessing but subscribing to the first group cannot know information about the group call of the first group.
In the group notification method provided by the embodiment of the invention, after the MCPTT server establishes the group call of the first group, when the state, the call type and the call priority of the group call change, the MCPTT server sends the group change notification information to the user equipments corresponding to all the group members in the first group, so that all the group members in the first group can acquire the update information of the group call, thereby solving the problem that the user equipment which does not access the first group but signs the group cannot later access the established group call, and facilitating the user to quickly and accurately select the group call to realize the group scanning function.
Fig. 2 is a schematic flow chart of another embodiment of the group notification method provided by the present invention, and as shown in fig. 2, the method includes the following specific implementation steps:
s21, the first ue sends a group call setup request to the MCPTT server, where the group call setup request includes an identifier of the first group.
S22, the MCPTT server obtains the identification of the second user equipment from the group management server according to the identification of the first group.
S23a/S23b, the MCPTT server sends a group call setup request to the second user equipment.
S24a, a portion of the second user equipment sends an accept access response to the MCPTT server.
S24b, another part of the second user equipment sends a response to the MCPTT server denying access.
The second user equipment receiving the group call establishment request sent by the MCPTT server determines the number of the currently accessed group calls, judges whether the number of the currently accessed group calls exceeds a preset maximum value or not, and sends an access refusing response to the MCPTT server if the number of the currently accessed group calls exceeds the preset maximum value; and if not, sending an access grant response to the MCPTT server.
Optionally, when the second user equipment determines that the number of currently accessed group calls exceeds the preset maximum value, the second user equipment may select to access a newly-accessed group call according to a policy and release the accessed group call. The policy in the above implementation means specifically refers to a priority of a subscription group preset by the second user equipment. When the number of the second user equipment which has been accessed to the group call currently exceeds the preset maximum value, the second user equipment can still be ensured to be accessed to the group call with high priority.
S25, the MCPTT server establishes the group call according to the first user equipment and the second user equipment sending the response of agreeing to access.
The MCPTT server sets the group state as an activated state while establishing the group call of the first group.
S26a/S26b/S26c, when the group call is changed, the MCPTT server sends the group change notification information to the user equipment corresponding to all the group members in the first group. Wherein the content of the first and second substances,
the group change notification information includes at least one of state change information, call type change information, and call priority change information of the group call.
As shown in fig. 2, the MCPTT server in this embodiment sends group change notification information to the user equipments corresponding to all group members in the first group, so that all the user equipments in the first group obtain the relevant information of the first group, thereby implementing a group scanning function and quickly and accurately selecting a group call. The group scanning function of the user equipment means that the user equipment acquires the related information of the user signed group by receiving the group change notification information sent by the MCPTT server, so as to realize the real-time scanning of the signed group.
Optionally, the MCPTT server sends the group change notification information to the user equipment corresponding to all group members in the first group, which specifically includes the following steps:
the MCPTT server inquires a group management server, and determines whether all group members in the first group have group members supporting multicast transmission;
if the group members supporting multicast transmission exist, sending group change notification information to user equipment corresponding to the group members supporting multicast transmission through a multicast channel; and if no group member supporting multicast transmission exists, sending group change notification information to the user equipment corresponding to the group member not supporting multicast transmission through a unicast channel.
Specifically, if the MCPTT server determines that there is a group member supporting Multicast transmission, the group member is broadcasted through an enhanced Multimedia Broadcast Multicast Service (eMBMS) Multicast channel, so that the user equipment corresponding to the group member supporting Multicast transmission can receive the group change notification information on the eMBMS Multicast channel;
fig. 3 is a schematic flowchart of a multicast notification process of the group notification method provided in the present invention, and as shown in fig. 3, the following situations are included in the MCPTT server broadcasting the group change notification information through the eMBMS multicast channel:
after the group call of the first group is successfully established, the MCPTT server sends N1 times group change notification information through the eMBMS multicast channel, and the notification information is used for notifying user equipment corresponding to all group members of the first group that the group state of the first group is changed from an inactive state to an active state. The interval period of each transmission is T1. N1 is a positive integer, which can be set as required, and this embodiment is not limited thereto. For example, T1 is 160ms, which can be set as required, and this embodiment is not limited to this.
During the group call existence period (i.e. in the active state) of the first group, the MCPTT server periodically sends group state change information through the eMBMS multicast channel for notifying the ues corresponding to all the members of the first group that the group state of the first group is in the active state, and may set an interval period T2 for each sending, for example, T2 is 5 s.
When the group call of the first group is closed, the MCPTT server sends N2 times of group change notification information through the eMBMS multicast channel, and the notification information is used for notifying user equipment corresponding to all group members of the first group that the group state of the first group is changed from an active state to an inactive state. The interval period of each transmission is T3. N2 is a positive integer, which can be set as required, and this embodiment is not limited thereto. For example, T3 is 160ms, which can be set as required, and this embodiment is not limited to this.
Optionally, when the group call type is changed or the priority of the group call is changed, the MCPTT server also sends N2 times of group change notification messages, which are used to notify the ue corresponding to all the group members of the first group that the group call information of the first group is changed. The interval period of each transmission is T3. N2 is a positive integer, which can be set as required, and this embodiment is not limited thereto. For example, T3 is 160ms, which can be set as required, and this embodiment is not limited to this.
Specifically, if the MCPTT server determines that there is no group member supporting multicast transmission, that is, the group member is a unicast user, the MCPTT server sends a group change notification message through a unicast channel (point-to-point).
Specifically, the Group change notification information in this embodiment includes, in addition to the Group Status (Active, inactive), the following: the identity Group ID of the Group Call, the timestamp Time Stamp, the Call Type (broadcast Call, emergency Call, etc.), and the Call Priority. Wherein the timestamp is used to indicate the sending time of the group change notification information.
Optionally, the group change notification information in this embodiment may adopt a TBCP format or an SIP format, and uplink response feedback information is not required when the TBCP format is adopted.
