Correspondingly, the broadband cluster core network receives the Message sent by the dispatching desk.
S102: the broadband cluster core network sends a cluster SHORT MESSAGE (trunk MESSAGE TRANSPORT) to the broadband cluster base station, carries the content of the cluster SHORT MESSAGE (trunk DOWNLINK TRANSPORT), indicates that the MESSAGE Type (MESSAGE Container Type) of the cluster SHORT MESSAGE is 'SHORT data and state data', carries an SDS MESSAGE SHORT-MSG in the MESSAGE Container, carries Calling party, called party, mode =01H (PTM), and initiates a multicast SHORT data sending process to the broadband cluster base station through the cluster SHORT MESSAGE. Wherein the process may be in parallel for each base station.
Correspondingly, the broadband cluster base station receives the cluster short message sent by the broadband cluster core network.
S103: the broadband cluster core network sends SIP (200 OK) to the dispatching desk to confirm that the short data is sent.
Accordingly, the dispatcher station receives the SIP (200 OK) sent by the broadband trunking core network.
S104: the broadband trunking base station sends a trunking paging (trunking paging) message to the broadband trunking terminal through a Trunking Paging Control Channel (TPCCH), wherein a trunking paging message Indication (trunking paging msg-Indication) value is true.
It is worth to say that, if the group is calling at this time, this step can be omitted; if the group is not established, after receiving the trunk MESSAGE TRANSPORT MESSAGE, the broadband TRUNKING base station should send a downlink TRUNKING direct transfer MESSAGE (dltrunk information transfer) including the multicast short data according to a Temporary Control Channel (TCCH) established in the carried calling area, and delete the TCCH channel after the multicast short data is sent, and the broadband TRUNKING terminal executes the same operation.

There is no timing relationship among S103, S104 and S105.
It should be noted that, in the related art, the B-TrunC protocol does not explicitly explain the association relationship between trunkpaining and the group, and generally implements B-TrunC communication by using two manners, one is that a wireless air interface needs to send TrunkPaging every time a trunking short message is sent, and the other is that the wireless air interface can continuously send trunking short messages.
However, if the first method is adopted to implement B-TrunC communication, the problems of low code rate, large occupied resources and the like of TrunkPaging may be caused; if the second method is adopted to realize the B-TrunC communication, the cluster short message loss, such as short data loss, may be caused.
The inventor obtains the inventive concept of the present application after creative work: and after receiving an indication message sent by the broadband trunking base station, the broadband trunking terminal deletes the TCCH channel according to the indication message, wherein the indication message is used for indicating the broadband trunking terminal to delete the TCCH channel used for transmitting the trunking short message.
The following describes the technical solutions of the present application and how to solve the above technical problems 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. Embodiments of the present application will be described below with reference to the accompanying drawings.
According to an aspect of the embodiments of the present application, the embodiments of the present application provide a group communication method for broadband clustering, which may be applied to the system architecture shown in fig. 1.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a group communication method of a broadband cluster according to an embodiment of the present application.
As shown in fig. 3, the method includes:
s201: a User Equipment (UE) receives an indication message sent by a network device, where the indication message is used to indicate the UE to delete a TCCH channel used for transmitting a trunking short message.
The user equipment may be a broadband trunking terminal as shown in fig. 1, and for the description of the broadband trunking terminal, reference may be made to the above example, which is not described herein again.
Also, the user equipment may be mobile terminals such as mobile telephones (otherwise known as "cellular" telephones) and computers with mobile terminals, e.g., mobile devices that may be portable, pocket, hand-held, computer-included, or vehicle-mounted, that exchange language and/or data with the radio access network; the user equipment may also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a tablet, a Wireless modem (modem), a handheld device (handset), a laptop (laptop computer), a Machine Type Communication (MTC) terminal, or other devices; the User Equipment may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Equipment (User Device or User Equipment), and the like, and is not limited herein.
The network device may be a broadband trunking base station as shown in fig. 1, and for the description of the broadband trunking base station, reference may be made to the above example, which is not described herein again.
It should be noted that, as can be known from the description of the related art, when the trunking short message needs to be transmitted between the user equipment and the network equipment, a TCCH channel between the user equipment and the network equipment needs to be established, and the trunking short message is transmitted through the established TCCH channel, for example, the network equipment sends the trunking short message to the user equipment through the TCCH channel, and the user equipment receives the trunking short message sent by the network equipment based on the TCCH channel.
However, in the related art, after transmitting the cluster short message each time, the network device and the user equipment delete the TCCH channel, and then re-establish the TCCH channel for transmitting the cluster short message, but in the embodiment of the present application, the user equipment deletes the TCCH channel only when receiving the indication information for deleting the TCCH channel, so that the network device may transmit the cluster short message to be transmitted based on the TCCH channel without repeatedly constructing the TCCH channel, thereby avoiding performance consumption of frequently deleting and constructing the TCCH channel, realizing saving resources of a wireless air interface, and improving reliability of group communication.
S202: and the user equipment deletes the TCCH channel according to the indication message.
That is to say, in the embodiment of the present application, the TCCH channel is deleted only after the ue receives the indication message, and the ue does not delete the TCCH channel until the indication message sent by the network device is not received, so that performance consumption of frequently deleting and constructing the TCCH channel is avoided, resources of a wireless air interface are saved, and reliability of group communication is improved.
In order to make the reader understand the scheme of the embodiment of the present application more thoroughly, the group communication method of the broadband cluster according to the embodiment of the present application is described in more detail with reference to fig. 4.
As shown in fig. 4, the method includes:
s301: and the dispatching desk sends the Message to the broadband cluster core network.
For S301, reference may be made to S101, which is not described herein again.
S302: the broadband cluster core network sends the cluster short message to the network equipment.
Wherein, the description of S302 with reference to S102 is omitted here.
S303: the broadband cluster core network sends SIP (200 OK) to the dispatching desk to confirm that the short data is sent.
Wherein, the reference to S103 for S303 is not repeated here.
S304: if the group is established and the preset keep-alive time length is not reached, the network equipment does not need to update the trunk paging message, and can send the cluster short message to the user equipment through the TPCCH.
The keep-alive duration can be determined by the network device based on the received cluster short message.
This step may include: the network equipment judges whether the group is established or not, judges whether the keep-alive time is reached or not if the group is established, does not need to update the trunk paging message if the keep-alive time is not reached, and sends the cluster short message to the user equipment through the TPCCH.
For the related processes that are not established in the group, reference may be made to the above example, which is not described herein again.
If the judgment result in the above example is that the keep-alive time length is reached, the network device updates the trunk paging message, establishes the TPCCH, and sends the trunking short message to the user equipment according to the established TPCCH.
S305: the network device sends a DLTrunkingInfomationTransfer message to the user equipment.
For S305, refer to S105, which is not described herein again.
S306: the network equipment sends an indication message to the user equipment, wherein the indication message is used for indicating the user equipment to delete the TCCH channel used for transmitting the trunking short message, and the indication message comprises the keep-alive duration.
Correspondingly, the user equipment receives the indication message sent by the network equipment.
That is to say, the indication message may carry a keep-alive duration, and the user equipment deletes the TCCH channel according to the keep-alive duration. For example, when the user equipment determines that the current time reaches the keep-alive time, the TCCH channel is deleted.
S307: and the user equipment deletes the TCCH channel according to the indication message.
In the embodiment of the application, the network device stores the keep-alive duration in advance, and sends the keep-alive duration to the user equipment, so that whether the current time reaches the keep-alive duration or not can be judged when the group is determined to be established, if not, the TrunkingPaging message needs to be updated, and the TrunkingPaging message can be sent to the user equipment through the TCCH, thereby avoiding the defect of more resource consumption of a wireless air interface caused by the fact that the TrunkingPaging message needs to be sent each time the network device sends the trunkingshort message to the user equipment in the related art, and realizing the technical effect of saving resources.
In the above example, the time for the user equipment to delete the TCCH channel is implemented by sending the keep-alive duration to the user equipment by using the network equipment, and in other embodiments, the indication information for indicating the user equipment to delete the TCCH channel may also be sent to the user equipment when the network equipment confirms that the group short message is sent completely, which is described in detail with reference to fig. 5.
As shown in fig. 5, the method includes:
s401: and the dispatching desk sends the Message to the broadband cluster core network.
For S401, reference may be made to S101, which is not described herein again.
S402: the broadband cluster core network sends a trunk MESSAGE TRANSPORT to the network device.
Wherein, the description of S402 is omitted with reference to S102.

Wherein, the description about S403 with reference to S103 is omitted here.
S404: if the group is not established, after the network equipment receives the cluster short message, establishing a TCCH channel, and transmitting the cluster short message to the user equipment based on the TCCH channel.
