The structure diagram of the TD cluster UE group implementation apparatus. detailed description

FIG. 1 is a schematic flowchart diagram of a method for implementing a TD cluster UE group according to an embodiment of the present invention. As shown in FIG. 1 , the radio resource control RRC layer of the cluster UE includes an idle mode and a connection mode. When the RRC layer is in a connected mode, the cluster UE implementing the group method includes: The cluster UE enters a speaking state, so that the cluster UE acquires a group of call rights and exclusively occupies an uplink dedicated channel of the group communication; when the RRC layer is in an idle mode, the cluster UE implements a group method, including S101: Control the cluster UE to enter a listening state, so that the cluster UE is in a receiving state in the group, and shares a downlink traffic channel of the group communication with all listening state UEs in the group.

In the above technical solution of the embodiment, the RRC state of the cluster UE is divided into an IDLE state and a T_DSCH state when there is no connection with the UTRAN, and a new function is to receive the cluster T-FACH resource on the BCCH in the IDLE state. Receiving the group call service configuration information on the T-FACH channel and performing related configuration; in the T-DSCH state, the state is a unique state in the cluster, specifically, only the downlink traffic channel (in the receiving state) in the group service, The UE state of the behavior common channel (RACH channel), that is, the UE in the listening state in the cluster. When connected to UTRAN, the T-CELL-DCH state is added. T CELL DCH, the UE has an uplink dedicated channel, and the next action group shares the user channel, specifically A UE with voice rights in the cluster, that is, a UE in a state in the cluster. And according to the state defined above, the cluster UE may form a group or join an existing group. For example, in step S102, a group of the UE is set up from the IDLE state to the T-CELL-DCH state, and may also join the cluster. An existing group, as in step S101, joins a group of clustered UEs from the IDLE state to the T-DSCH state. The above states the RRC state to be re-divided to meet the needs of implementing the cluster function.

More specifically, the foregoing states can be mutually converted during the entire process of group grouping and releasing groups of the cluster, so that the cluster UE can be repeatedly changed, and the users in the group can talk and communicate until the group call ends. the goal of.

FIG. 2 is a schematic diagram showing transitions between states of a TD cluster UE group according to an embodiment of the present invention. Referring to Fig. 2, since the CELL-FACH inherits the original TD system, and migrates from the IDLE state to the CELL-FACH state A and from the CELL-FACH state to the IDLE state B, the original TD system is used, and will not be described here. The following is a detailed description of the functions in each state of the TD cluster and the transition between states.

In the IDLE state, in order to implement the group function of the cluster UE, the new IDLE state function is to receive the cluster T-FACH resource on the BCCH, and receive the configuration information of the group call service on the T-FACH channel and perform related configuration.

State 2: The T-DSCH state, which is a unique state in the cluster, specifically refers to the UE state in which only the downlink traffic channel (in the receiving state) and the upper-behaving common channel (RACH channel) are in the group service. The status function is as follows: Normally receive group service signaling and data; Receive a serving cell system message, and can update the changed broadcast message in time; Monitor and receive a paging message, which is used to initiate a hybrid service or access a high priority service. ; Perform autonomous switching; call right application.

State 3: T—CELL—DCH, the UE has an uplink dedicated channel, and the next is the user shared channel in the group. The status function is as follows: Measurement Control; Select and configure the RB multiplexing option applied to the transport channel used in this RRC state; Process the RRC message received on the DCCH.

Referring to FIG. 2, the above state 1, state two, and state three transition processes are as follows: State transition C: The IDLE state is migrated to the T-CELL-DCH state. After the cluster UE initiates a group service call, it enters the IDLE state and transitions to the T-CELL-DCH state. At this time, the uplink traffic channel is dedicated, and the downlink traffic channel is a group. Internal user sharing.

^! Dog state migration D: The T CELL DCH state migrates to the IDLE state. After the UE in the T-CELL-DCH state receives the service release message, the cluster UE transitions from the T-CELL-DCH state to the IDLE state.

State transition E: The T-DSCH state is migrated to the T-CELL-DCH state. The UE of the listening user that is already in the group service is switched from the T-DSCH state to the T-CELL-DCH state after receiving the call right.

State transition F: T_CELL—The DCH state migrates to the T-DSCH state. It is already in the group service. The user's UE jumps from the T-CELL-DCH state to the T-CELL-DCH state after receiving the right release message or the call release request. T-DSCH state.

State transition G: The IDLE state is migrated to the T-DSCH state. After receiving the paging message of the group service and correctly receiving the service resource configuration message, the UE in the IDLE state enters the T-DSCH state, which is the UE autonomous. Conversion, no network side specification is required.

State transition H: The T-DSCH state transitions to the IDLE state. The UE that has been in the group service listens to the user and enters the IDLE state from the T-DSCH state after receiving the group service release message.

The foregoing embodiment demonstrates the process of transitioning between states of the cluster UE. By re-dividing the RRC state, the group function of the cluster UE can be completed on the basis of the original TD system, and the users in the group can communicate and communicate.

FIG. 3 is a flow chart showing the release of a cluster UE from an access group to a group according to an embodiment of the present invention. Referring to FIG. 3, in this embodiment, after a cluster UE reads the cluster-related SI, it will camp on the cluster cell and enter the IDLE state. The method for implementing the TD-cluster UE group may include the following steps: Step 1: When the group in which the cluster UE is located exists, the physical resource of the group is read, and the group is accessed, and the UE is migrated from the IDLE state to the T- DSCH state.

Step 2: In the call right application process, the cluster UE applies for the right to call the network, when the network is the UE After the call rights are allocated, the UE moves from the T-DSCH state to the T-CELL-DCH state.

Step 3: The group release process, the higher priority cluster UE initiates a release request to the network, and when the network releases the belonging group, the UE migrates from the T-CELL-DCH state to the IDLE state.

The above embodiment is a typical access group-to-group release process, that is, a group of clustered UEs already exists. For any cluster UE that wants to join the group, the UE can enter the listening state from the idle state through the foregoing process. Then, from the listening state to the speaking state, of course, the user can also perform mutual conversion between states according to the specific call communication needs, and achieve the purpose of group communication.

FIG. 4 is a flowchart of a cluster UE from group grouping to group release according to an embodiment of the present invention. Referring to FIG. 4, in this embodiment, after a cluster UE reads the cluster-related SI, it will camp on the cluster cell and enter the IDLE state. The TD cluster UE group implementation method may specifically include:

Step (1): The group call establishment process, the cluster UE applies to the network to form a group, and after the network establishes a radio link and other resources for the group, the UE migrates from the IDLE state to the T-CELL-DCH state.

Step (2): During the release of the voice right, after the cluster UE initiates the release of the call right to the network, the network releases the call right of the UE, so that the UE migrates from the T-CELL-DCH state to the T-DSCH state.

Step (3): During the group release process, the cluster UE initiates a release request to the network. After the network releases the group, the UE migrates from the T-DSCH state to the IDLE state.

The above embodiment illustrates a typical group establishment to group release process by migrating states in the TD cluster in the trunking communication system. That is to say, the cluster UEs form a group and realize the state from the idle state to the state, and then return from the state to the idle state. Of course, the user can also perform mutual conversion between states according to the specific call communication needs, and achieve the purpose of group communication. .
