Group system needs the mobility supporting to comprise RRC connected state right of speech UE and non-right of speech UE, the mobility of wireless heterogeneous networks (RadioResourceControl, RRC) Idle state (non-right of speech UE) UE.
Compare public network system, cluster has newly increased clustered control channel (TrunkingControlChannel, and group service channel (TrunkingTrafficChannel TCCH), TTCH)---the point-to-multipoint down channel that cluster is special, be respectively used to transmission group's control information and downlink service data, newly increase clustered paging control channel (TrunkingPagingControlChannel, TPCCH)---the common down channel of point to multipoint mode, the beep-page message of transmission trunking group calling and individual calling.
The RRC information clustered paging (TrunkingPaging) newly increased is carried on TPCCH, and RRC information group configuration (GroupCallConfig) message newly increased and group's release (GroupCallRelease) message bearing are on TCCH.Meanwhile, descending cluster information transmission (DLTrunkingInformationTransfer) message bearing has been newly increased on TCCH.
In the private network broadband cluster system of existing TD-LTE technology, cell reselection process comprises: UE is when connected state, when cell merge completes, continue in Target cell to receive group service, in cell switch process, UE connects to reshuffle in (RRCConnectionReconfiguration) message at RRC to obtain cluster information, but not obtains cluster information by TrunkingPaging message and GroupCallConfig message.This process does not need to optimize.
UE when idle (Idle) state, if tracking area (TrackingArea, TA) does not change, UE target approach community, after receiving the periodicity clustered paging of Target cell and group's configuration, complete self configuration, can continue in Target cell to receive group service.
UE is when Idle state, if TA changes, first UE carry out Stochastic accessing in Target cell, set up RRC connects, and the clustered paging of receiving target community and group's configuration, complete tracing section updating (TrackingAreaUpdate, TAU) afterwards.
Listen UE (non-right of speech UE) to be substantially all in Idle state in group, if TA does not change, then because need to wait until periodically clustered paging, can group service be continued, have certain delay.If TA changes, then need first to carry out RRC connection, distribute private resource to UE, UE is without the proprietary business of other outside group service subsequently, and eNB needs release RRC connection to enter Idle state.Waste Radio Resource, also increase signaling procedure.

Step 1:UE, when determining to meet cell re-selection conditions, initiates cell reselection process.
Wherein, described cell re-selection conditions, such as: UE at least resides the 1s time in current service cell, for co-frequency neighbor cell, if the large 3db in power ratio Serving cell of adjacent area, with regard to gravity treatment to this adjacent cell.
Described initiation cell reselection process, specifically comprises: UE searches suitable community according to cell re-selection conditions, then resident to new community, read system information, obtains Random Access Channel (PRACH) configuration information etc.
Step 2:UE sends random access guiding (RAPreamble) to evolved base station (EvolvedNodeB, eNB).
Step 3: after this eNB receives the RAPreamble of this UE transmission, random access request (RAR) is sent to this UE, the uplink authorization of instruction msg3 resource is carried in this RAR, with Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (CellRadioNetworkTemporaryIdentity, C-RNTI), for the subsequent transmission of UE and eNodeB.
Step 4: after this UE receives the RAR of eNB transmission, information 3 (Msg3) is sent to this eNB, namely Idle state information (IdleInformation) is sent, this IdleInformation is the new CCCH information (namely this IdleInformation is carried on CCCH) of embodiment of the present invention definition, wherein carry NAS message, this NAS message comprise TAU request, cluster group group number (being safeguarded by core net), activate label (activeflag) for the mistake information such as (false).Wherein, activeflag is false when user is in Idle state, does not need to set up user plane bearer after being used to indicate core net TAU.
Wherein, above-mentioned steps 2-4, belongs to the random access procedure of UE, as can be seen from this process, in the embodiment of the present invention, does not set up RRC in this process and connects.NAS message is included in the RRC information of new definition, namely in IdleInformation.This message is UE reports network side eNB when Idle state mobility, comprises NAS message.After eNB receives, need to send UE initial message to core net (CN or eCN), wherein carry this NAS message.
Step 5: this eNB forwards this NAS message to core net by initial UE information (INITIALUEMESSAGE) message.
Step 6a: after this core net receives this INITIALUEMESSAGE message, if eNB does not have corresponding group service, request (TrunkingGroupContextSetupRequest) is set up, to notify that eNB sets up group service to this eNB signalling of bouquet group context; If existing corresponding group service in this eNB, but the current TA of this UE does not have corresponding group service, then this core net sets up group service by cluster group context modification request (TrunkingGroupContextmodifyrequest) message informing eNB at target TA.Otherwise, do not need to perform step 6a and step 7 below.
Wherein, about how judging that eNB does not have corresponding group service, can be such as: if the group that core net did not send this group to eNB sets up order or sent release, then determine that eNB does not have corresponding group service, need to send group's context and set up request, notice eNB sets up group service at target TA.
Group's RAB (RadioAccessBearer, the RAB) list carry group ID, TA list in TrunkingGroupContextSetupRequest, will setting up.
About how judging that the current TA of this UE does not have corresponding group service, can be such as: if the group that core net sent this group to eNB sets up order and do not discharge, TAI simultaneously in TAU message not included in the TA list that group sets up order, then determines that the current TA of this UE does not have corresponding group service.
The TA list of carrying increase in TrunkingGroupContextmodifyrequest and the TA list of deleting.
Step 7: if CN sets up group service by TrunkingGroupContextSetupRequest message informing eNB, then this eNB is according to TrunkingGroupContextSetupRequest message, sets up group service; If CN sets up group service by TrunkingGroupContextmodifyrequest message informing eNB at target TA, then this eNB is according to TrunkingGroupContextmodifyrequest message, sets up group service at target TA.
Wherein, this eNB, according to TrunkingGroupContextSetupRequest message, sets up group service, specifically comprises: group service is set up in the RAB list that eNB issues according to core net.
Step 6b: core net sends Trunkingpaging message to this eNB.
Wherein, in Trunkingpaging message, carry group identification, group network temporary mark G-RNTI, alternatively, group's default resource configuration index can also be carried.
Step 8: this eNB forwards this Trunkingpaging message to this UE.
Step 9: if do not comprise cluster default configuration in Trunkingpaging, then this eNB sends group calling configuration (Groupcallconfig) message.
Wherein, described cluster default configuration, comprise clustered control channel TCCH group service channel TTCH, the semi-static SPS configuration of cluster voice, configuration index is 0-15, corresponding different resource configuration parameters.Configuration index is carried in message.
GroupCallConfig message, for allocation cluster Traffic Channel TTCH, carries TTCH channel resource configuration information.
Step 10: this core net is carried NASTAU by cluster direct-sending message (DLTrunkingInformationTransfer) and accepted (accept) message to UE, also carries the terminal iidentification (MSidentity) of this UE in this DLTrunkingInformationTransfer message.By MSidentity, this UE confirms whether this NASTAUaccept message is one's own confirmation (Ack) message.
Carry TA in this TAUaccept message and upgrade result, the MSidentity in the embodiment of the present invention, as essential option, needs to be carried in this TAUaccept message.
As can be seen from above-mentioned flow process, in prior art, msg3 carries RRC connection establishment, carries out RRC connection building process.S1 release and RRC release is carried out after TAU.And msg3 carries the IdleInformation message of new definition in the new process that the embodiment of the present invention provides, do not set up RRC and connect, do not need to distribute and configuration UE specific resource.TAUAccept message is issued by cluster direct-sending message DLTrunkingInformationTransfer.Do not need after completing to carry out S1 release and RRC dispose procedure.Save Radio Resource, simplify signaling process.
