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.
Fig. 1 is a schematic structural diagram of a B-TrunC system according to an embodiment of the present invention. As shown in fig. 1, the system provided in this embodiment includes a cluster core network 101, a base station 102, and a user terminal 103. Wherein the cluster core network 101 may be a server or a cluster of multiple servers. The base station 102 may be a TD-LTE base station. The user terminal 103 may be a child story machine, a mobile phone, a tablet, a vehicle-mounted terminal, etc.
However, in the existing B-TrunC group establishment, when a group is established, a cluster core network needs to notify each base station, and establish air interface resources in the corresponding base station. However, since only one control signaling containing the group pre-establishment request can be sent to the base station by the cluster core network, in a large-scale networking scenario, the number of base stations corresponding to a group is large, and the sending capability of the cluster core network through the S1 interface is limited, which causes that air interface resources of part of the base stations cannot be established in time, and further causes that part of receiving end users in the group cannot receive data of the main speaking end in time, even causes a problem of data loss. In order to solve the technical problem, this embodiment provides a group establishment method, where a group to be established is configured in advance in a cluster core network, then configuration information is sent to each base station, and an air interface resource is established in advance on each base station, so that a group is established quickly in a large-scale networking scenario, and data loss is reduced. The following examples are given for illustrative purposes.

and determining the hot spot area range as the area range included by the group to be established.
In another embodiment of the present invention, if it is detected that any group is established in a predetermined fixed area for a predetermined fixed time for a predetermined number of consecutive times, and the number of base stations included in the established group exceeds a predetermined number, the established group is determined as the group to be established, and the base stations included in the established group are determined as the area range included in the group to be established.
In this embodiment, the service type of the group to be established is configured to be relatively stable, for example, if the group is established as a voice service, the group should also be a voice service next time, which indicates that the service type of the group should be relatively stable, and is suitable for being used as the group to be established. If the group is established as a voice service, the group should be a voice + video service next time, which indicates that the service type of the group is changed greatly and is not suitable for being established as a group to be established. Therefore, the service type of the group to be established is configured stably, and the problems of insufficient use of base station resources or waste can be avoided.
S202: and sending a group pre-establishment request to each base station in the area range, wherein the group pre-establishment request carries the group configuration information of the group to be established and the cluster core network side bearing identification, so that each base station stores the group configuration information, and does not allocate resources on an air interface and send a group establishment control signaling.
In this embodiment, the group configuration information of the group to be established includes a pre-established identifier of the group to be established and group establishment control information. The cluster core network side bearer identifier is a bearer identifier (i.e., a cluster core network side bearer ID) allocated by the cluster core network for the S1 port.

And establishing a bearer between the cluster core network and the base station for transmitting the group data through the bearer identifier of the cluster core network side and the bearer identifier of the base station side.
S204: and sending group data to each base station through a bearer between the cluster core network and the base stations, so that when each base station monitors that the group data on the bearer contains a group identifier of the group to be established, a group establishment control signaling is generated on an air interface according to the group configuration information, and the group establishment control signaling is sent to the user terminal through a multicast mode, so that the user terminal accesses the group to be established.
In an embodiment of the present invention, if the group pre-establishment request further includes other base stations outside the area range, the target base station shall notify the other base stations according to a common group establishment procedure after receiving the group data sent by the trunking core network.

and when the calling terminal identification of the group to be established is changed, sending a calling terminal change request to each base station so that each base station changes the identification of the calling terminal in the group configuration information.
In this embodiment, the priority change Request is a "Group Call Context Modification Request", and after each base station changes the priority information in the Group configuration information, the priority change Response information sent by the base station is received, where the priority change Response information is a "Group Call Context Modification Response".
And the calling terminal change request is 'Group Downlink Nas Transport', and after each base station changes the calling terminal information in the Group configuration information, the calling terminal change response information sent by the base station is received.
From the above description, according to the actual group establishment instruction, the different configuration information of the pre-established group and the actually established group is adjusted, so that the pre-established group is adjusted, and the accuracy of group establishment is ensured.
In an embodiment of the present invention, after the group service is ended, the cluster core network may select whether to control the base station to release the resource configured on the air interface of the group to be established according to a policy or a configuration.
Specifically, a release instruction of the group to be established is sent to each base station, so that each base station maintains the configuration resources of the group to be established on the air interface when determining that the release instruction of the group to be established carries the identifier for maintaining the group to be established.
In this embodiment, the Release instruction of the Group to be created is a "Group Call Context Release Command," and an identifier for maintaining the Group to be created is added to the Release instruction of the Group to be created, where the identifier for maintaining the Group to be created is "Pre-Setup Group — Suspend Indication.
And if the base stations determine that the releasing instruction of the group to be established does not carry the identifier for maintaining the group to be established, releasing the configuration resources of the group to be established on the air interface.
As can be seen from the above description, the cluster core network may notify the base station whether to release the configured resources of the group to be established according to the release instruction, so as to implement flexible configuration of group pre-establishment.
