  • Cluster communication refers to a dedicated scheduling communication method, including dedicated command and dispatch communication.
  • cluster users can simultaneously Join the call, and the call is made in simplex or half-duplex mode.
  • One method is to separately allocate an air channel for each cluster user terminal when the call is made into a cluster, and the user terminal is pressed according to the existing CDMA2000 IX normal voice.
  • the paging mode of the call that is, paging the incoming call according to the IMSI (International Mobile Subscriber Identity), and assigning the channel to the terminal when the terminal accesses the call also adopts the channel allocation mode of the ordinary voice call. Therefore, such a cluster call can break through the geographical limitation by separately allocating channels, and realize the roaming function, which is different from the existing professional cluster call, which is called an enhanced group call.
  • the air interface channel resource occupancy is related to the number of group users.
  • the channel usage number is 2N+1.
  • the enhanced group call is paged in IMSI mode (enhanced mode), and the user terminal pages the incoming call one by one, which inevitably increases the call connection time. Therefore, with the control method of the group call, the occupation of the air interface resource grows linearly with N, the connection time is long, the resources are occupied, and the capacity is limited. Especially in the place where the group users are concentrated, such as a large sports meeting, a large number of users need to be accessed at the same time. This enhanced group call method is unlikely to meet the requirements.
  • Another method is: when performing a trunking call, the network side sends a paging request carrying a group identifier (GID, Group ID) to all base station controllers in the group scheduling service area, and the base station controller receives the paging After the request, it is notified that all the transceivers establish a shared forward traffic channel and a shared reverse traffic channel, and the base station controller periodically broadcasts and sends the group identity addressing on the paging channel after the wireless channel is successfully established.
  • Call message the terminal belonging to the group is based on the message in the paging message Information, capturing the forward traffic channel established for the group, automatically in the access group. This type of call is referred to herein as a traditional group call.
  • This traditional group call uses channel sharing in the way of channel resource allocation, which solves the problem of cell capacity limitation and call connection time of the digital trunking system.
  • the shared channel resources are established in a limited number of cells, and the call mode is not supported for roaming users, and the mobility of some users cannot be satisfied. Network call requirements. Summary of the invention
