Background technology

The formal externally issue " Digital Clustering mobile communication system system " of Ministry of Information Industry's on December 28th, 2000, and recommend cluster to use land trunked radio (TETRA, Terrestrial Trunked Radio) and two kinds of systems of integrated digital enhanced network (iDEN, Integrated Digital Enhanced Networks).Domestic independent researches in several years subsequently based on code division multiple access (CDMA, Code Division Multiple Access) based on open cluster architecture of technology (GOTA, Global Open Trunking Architecture) and the GT800 based on global mobile communication system technology emerge.

Along with the develop rapidly of mobile Internet and the TD-LTE technology universal, the mobile communication broad band demand is more and more obvious, group system is also to future developments such as IPization system architecture, data are broadband.The end of the year 2010, the CCSA official approval " research report of the trunked communication system based on TD-LTE ", three kinds of implementations based on TD-LTE wideband multimedia cluster have been proposed in this report.

In group system, most typical business is group-calling service, and the user can at a time initiate the calling for a certain particular demographic, and this is called out and adopts semiduplex mode.In the wideband multimedia system, cluster not only can, for the user provides voice group call service, can also provide the business such as visual group calling.The group calling characteristics are only to allow at any one time a people to be talked, speaker obtains uplink resource, other users are in the state of answering, DSCH Downlink Shared Channel of each cell allocation that system relates to for this group, this shared channel of real-time listening per family for this group in community.Therefore, in the cluster multi call process, arbitrary moment only has a up link and a shared down link, than public network, has utilized more efficiently frequency spectrum resource.It is the operations such as right of speech allows to apply for, discharges, seizes, queuing that semi-duplex group is called out another characteristics, and the management process of right of speech and User Priority closely related.In addition, the group calling setup delay is one of key index of trunked call, and any one group system all needs to meet the system performance of access fast.Here define the group calling setup delay and press PTT (PUSH TO TALK, PTT) key to there being a called subscriber to hear the time of caller voice for the calling party.

The TETRA system is European standard, and clustering functionality is the most powerful, and system equipment and subscriber equipment are expensive, although the air interface external disclosure, secret but other interfaces of internal system are, between each equipment vendor, interoperability is not high.And the iDEN system is exclusive standard, system standard is not externally announced.

Domestic narrow-band digital group system, the for example GT800 based on GSM and the GOTA system based on CDMA, because its base station need to be unified to control by base station controller, can't directly communicate with core net, cause the Signalling exchange in group call establishment process to increase, increased calling establishment time delay.

In three kinds of TD-LTE wideband multimedia group schemes that CCSA proposes, the first scheme modifying air interface strengthen group calling performance purpose to reach, first scheme is that Push to talk over Cellular (PTT Over Cellular is used in suggestion, Poc) business is carried out enhancement method and is realized the broadband cluster, the third scheme is on the basis of using the Poc scheme, use multimedia broadcast/multicast service (Multimedia Broadcast/Multicast Service, MBMS) joint transmission mode to strengthen to reach the group calling performance.All there are some drawbacks in these three kinds of schemes at the group calling performance scheme, although the first scheme has been optimized air interface, but, owing to adopting TD-LTE core net public network framework, in group call establishment process, each equipment room of core net need to be repeatedly mutual, is unfavorable for the shortening of group calling setup delay; First scheme and the equal Application standard Poc of the third scheme business are carried out enhancement method, because limited space is optimized in the restriction of Poc business self flow process.Although the third scheme has adopted MBMS joint transmission scheme optimization air interface, to overall plan optimization not obvious.

After the start of subscriber equipment in TD-LTE wideband multimedia digital cluster system, this subscriber equipment carries out network attachment and sets up default bearing, is triggered to the dispatching services registration process of dispatch server by network equipment TMSE after adhering to successfully; In this process, complete the authentication of cluster user and the register and authentication of dispatching services;

When the user presses the PTT key and initiates the calling for certain designated group, if now calling subscriber equipment is in the IDLE state, calling subscriber equipment first carries out the RRC connection, enters connected state, then by NAS message, sends group calling and sets up request to network equipment TMSE;

After TMSE receives the group calling request of setting up, judge whether authentication success of this user, if success send and invite (Invite) message to dispatch server; If failure refuse this time group calling request of this subscriber equipment;

After dispatch server is received Invite message, judge whether this calling subscriber equipment has registered dispatching services, and judge whether this calling subscriber equipment has the right to initiate this group calling, if, respond 181 message of Invite to TMSE, notice TMSE sets up unidirectional service bearer for this calling subscriber equipment; If this calling subscriber equipment registration dispatching services failure, respond the errored response 480 of Invite to TMSE, refuse this time group calling request of this calling subscriber equipment;

Dispatch server send 181 message to TMSE after, trigger and to exhale eventually the TMSE of Invite message to all connections, the group calling that notice is initiated by a calling subscriber equipment, need to set up DSCH Downlink Shared Channel for it;

Allly receive that the TMSE that exhales Invite message this end all judge that according to the group of carrying in this message sign this group identifies in corresponding group and whether has subscriber equipment to be served by this TMSE, if do not have, responds 404 message to dispatch server; If have, in triggering group, the paging to subscriber equipment in this group is initiated in community, subscriber equipment place;

No matter organize interior subscriber equipment and now may still connect (CONNECT) state in idle (IDLE) state, can this paging of normal response, and add in group session;

As long as a user device responsive has been arranged this paging, network sends group calling and is successfully established message, and carries right of speech and license to group calling promoter, i.e. calling subscriber equipment;

The group calling promoter loquiturs after receiving the right of speech mandate, and this time group call establishment process completes.

Wherein, above-mentioned cluster user start-up logging flow process, referring to Fig. 2, comprises step:

A1.UE sends Attach Request message and cluster network selects indication to eNB, this Attach Request message comprises: international mobile subscriber identifier (International Mobile Subscriber Identifier, IMSI) or old global unique temporary identity (Globally Unique Temporary Identity, GUTI), tracking area identification (the Tracking Area Identity of effective last visit, TAI), UE core network ability, the discontinuous reception of UE appointment (DRX) parameter, the PDN type, protocol configuration option (PCO), Encryption Options transmission mark, type of attachment, KSIASME(Key Set Identifier Access Security Management Entity), the NAS sequence number, NAS-MAC(Non-Access Stratum-Media Access Control) and additional GUTI.

Old global unique temporary identity (GUTI) and cluster that A2.eNB controls in (Radio Resource Control, RRC) message parameter according to the Radio Resource that carries UE and adhere to request select network to indicate, and obtain the sign of new TMSE.If can not get the sign of new TMSE, the TMSE sign that eNB is new according to policy selection such as loads.

Then, eNB is transmitted to new TMSE together by the TAI of Attach Request message and community, UE place and Evolved UTRAN network (E-UTRAN) Cell Global Identity (E-UTRAN Cell Global Identifier, ECGI).

If A3. UE identifies oneself by GUTI, and the TMSE under UE is because attachment removal changes, new TMSE is used the address that obtains old TMSE from the GUTI of UE, and send the identify label request message to old TMSE, the IMSI of request UE, old TMSE returns to identification response and gives new TMSE, comprising the IMSI of UE and untapped EPS Ciphering Key and KSIASME, KASME, gives new TMSE; If old TMSE can not identify the integrity checking failure (identical with the protection algorithm integrallty of standard in existing 3GPP agreement) of UE or Attach Request message, old TMSE returns to suitable wrong reason (" User authentication failed ") to new TMSE.

If A4. in new, old TMSE, all can not identify UE, new TMSE send identification request to UE with request IMSI.UE is used the identification response message that comprises IMSI to notify to network.

If A5. in network, there is no the UE context; and the Attach Request message in steps A 1 does not have integrity protection or encryption; if perhaps integrity checking failure, the safe process of establishing of the authentication of this step and NAS (the 3GPP protocol procedures that these two processes are all standards) forces to carry out.Otherwise this step can not carried out.

If the NAS security algorithm changes, this step is only carried out the safe process of establishing of NAS.

After this step, all NAS message will be subject to the NAS safety function protection of TMSE indication.

If A6. in new TMSE, there is the bearer context activated, for example, do not have prior attachment removal just again to adhere at same TMSE, delete old bearer context.If TMSE changes after last attachment removal, or adhere to for the first time, or ME sign (ME Identity) changes, or IMSI or GUTI that UE provides do not have corresponding bearer context information in TMSE, TMSE sends position updating request to HSS, wherein, this position updating request comprises TMSE sign (TMSE Identity), IMSI, ME Identity, TMSE ability (TMSE capabilities) and updating type (Update type).Wherein, the TMSE ability has been indicated the access limitation function status that this TMSE supports; It is an attaching process that updating type has been indicated this.

A7.HSS sends the position deletion request message to old TMSE, and old TMSE deletes mobile management and bearer context.If old TMSE has the bearer context of activation to exist, old TMSE deleting bearing resource.

A8. old TMSE deletes response message to the HSS home position.

A9.HSS sends position and upgrades response message to new TMSE, to reply the renewal location message.This position is upgraded in response message and is included IMSI and subscription data, and subscription data comprises the signing contextual information of one or more PDN.The Aggregate Maximum Bit Rate (APN-AMBR) that comprises signing qos parameter and signing APN in each signing context.New TMSE checking UE exists in new tracking area (TA).If due to territorial restrictions or access limitation, do not allow UE to be attached in this TA, the TMSE refusal adheres to request.If check successfully, new TMSE creates a context to UE.If to be signing institute unallowed or HSS has refused the renewal position for the APN that UE provides (Access Point Name, APN), new TMSE refusal Attach Request message.New TMSE creates default bearing for the user, and is UE distributing IP and cluster group IP address;

A10. new TMSE creates default bearing for the user, and be UE distributing IP address and cluster group IP address, send initial context and set up request (adhere to and accept message (Attach Accept)) to eNB, wherein carry APN, GUTI, PDN type (PDN Type), PDN address (PDN Address), TAI list (TAI List), EPS bearing identification (EPS Bearer Identity), session management request (Session Management Request), protocol configuration option (Protocol Configuration Options), KSIASME, NAS serial number (NAS sequence number) and NAS-MAC, and need to carry cluster group sign and group IP address.

If new TMSE distributes a new GUTI, GUTI is also contained in this message.It is inner that this message is included in cluster S1 interface (S1_T) control message initial context foundation request (Initial Context Setup Request), and this S1 control message also comprises that Aggregate Maximum Bit Rate (UE-AMBR), the EPS of Access Layer (AS) safe context, switching restriction list, carrying QOS parameter and the UE of UE carry ID and SGW user's face TEID and address.

A11.eNB sends RRC and connects reconfiguration message to UE, wherein comprises RB ID and the AttachAccept message of EPS system.

A12.UE sends the RRC connection and has reshuffled message to eNB.

A13.eNB sends initial context and sets up response (Initial Context Response) message to new TMSE.The TEID that comprises eNB in this Initial Context Response message and the ，Gai address, address of eNB are for the downlink business of cluster S1 interface user plane (S1_Tu) reference point.

A14.UE sends (Direct Transfer) message that direct transfers to eNB, this message comprises has adhered to (Attach Complete) message, in this Attach Complete message, comprises: EPS Bearer Identity, NAS sequence number and NAS-MAC.By Attach Complete message, UE brings into use the NAS security algorithm of new TMSE indication.

A15.eNodeB is used up NAS message transfer to forward Attach Complete message to new TMSE.UE, after adhering in accepting message and obtaining the PDN address information, just can send the upstream data bag to eNodeB, and eNodeB seals upstream data to be contained in GRPS tunnel protocol (GTP-U) tunnel and to be uploaded to new TMSE.If the PDN type (Ipv4 and Ipv6) of UE request double address, but network only allows single-address PDN type (Ipv4 or Ipv6), and network only supports the carrying of single-address type, UE can ask the PDN that activates another address style under identical APN to connect again.

A16. all forming that new TMSE is this UE place built cluster group downlink bearing link.For each group, new TMSE sets up new TMSE to the unidirectional GTP-U tunnel between eNB, the downlink data for carrying from new TMSE to eNB.

A17.UE is by direct-sending message, registration request; Perhaps new TMSE is sent in the net Indication message to scheduling Server, and this message is carried by SIP registration request (SIP REGISTER) message.Carry the information such as user ID, affiliated group of information and TMSE address in this message.

A18. dispatch Server and receive that this,, after the net Indication message, carries out the dispatching services authentication to this UE, after the authentication success, respond 200OK message to new TMSE.If failed authentication, respond the dispatching services registration failure that the errored response code is indicated this UE of TMSE, new TMSE needs the registration failure information of recording dispatching business, when UE initiation next time group-calling service, is refused.New TMSE direct transfers by descending NAS message, and this 200OK message is sent to UE.

Referring to Fig. 3, the group calling Establishing process that the cluster user that the embodiment of the present invention provides is initiated comprises step:

If 1, UE1 does not have Radio Resource to control (Radio Resource Control, RRC) connection, first set up RRC and connect.Then, UE1 initiates group calling and sets up request to network, and this group calling is set up request and transmitted by Non-Access Stratum (Non Access Stratum, NAS) Packet Data Unit (Packet Data Unit, PDU).

ENB 1 receives after request is set up in this group calling and passes through TMSE1;

2, after TMSE1 receives that request is set up in this group calling, this group calling request of setting up is converted to dialogue-based initiation protocol (Session Initiation Protocol, SIP) invitation (Invite) message, and send to the scheduling Server, in this message, carry: calling number (initiating group calling square mark or number), and called number (needing group identification or the number called out).

If mistake appears in 3 scheduling Server inside, or determines that this UE1 haves no right to initiate group calling, is not this group user etc. such as calling party UE1, respond errored response code 408 to TMSE1, when TMSE1 receives errored response code 408, discharge RRC by timer and connect;
