Preferred embodiment
This preferred embodiment provides a kind of terminal based on LTE flow process and method that (subscriber equipment) registers, take the LTE wide-band mobile communication system as support, incorporates the cluster characteristic, has both expanded the functional of LTE, has widened again the application of trunked call.
The present embodiment increases the group system sign of supporting in the system broadcast information message of LTE, so that notification terminal will carry out the group service registration at cluster EPC.On the flow process that realizes to the LTE network element between protocol interface expand, both realized the independence that the group service registration realizes, support again the demand that cluster network and standard LTE are network coexisted simultaneously.The air interface aspect, standard LTE idle message content is expanded, increase the cluster parameter information, for example, public land mobile network (the Public Land Mobile Network that selects, referred to as PLMN) information, group identification number (Identity is referred to as ID) etc., such idle message format design, both can adopt primary standard LTE space interface signaling, also can use self-defining cluster message, so that the compatible former LTE of the realization of clustering functionality system; The terrestrial interface aspect considers that in the realization, it is cluster EPC that group service adopts its special-purpose core net to the compatibility of original LTE system.Base station and core net are carried out the ground transmission of messages by this cluster terrestrial interface message.
The interactive information of terminal registration content is all only carried out in cluster SRB1 carrying, does not need to set up the DRB Deta bearer again, has effectively solved the problem of the wasting of resources.In the flow process that realizes, can optionally carry out the inquiry of UE ability information.
Mutual register information all transmits in NAS message between terminal and the cluster core net (the present embodiment intermediate range cluster EPC is the cluster core net), so that the invisible registration message content of other intermediate NE, thereby really realize confidentiality and the fail safe of end-to-end information.
After registration is finished, configure the shared wasting of resources for avoiding eNB, need to discharge UE and connect.The context of release herein and standard LTE discharges different, because also do not set up context this moment, so adopt custom-designed release flow process to process.
Be the Integral Thought of preferred embodiment more than, its implementation procedure comprises that step S602 is to step S610 as shown in Figure 6.
Step S602: the base station is to fill in the informational message to support the group system sign in system broadcasts, and notification terminal will be registered at the cluster private network.
Step S604: terminal begins register call, carries out cluster RRC and connects foundation, sets up cluster SRB1 signaling bear, in order to transmit dedicated control signaling.It is group service that current business is adjudicated according to the cluster parameter information in the message in the base station.
Step S606: terminal is linked into the process of cluster core net by eNB, sets up the cluster terrestrial interface connection that eNB is connected with cluster EPC.Here adopt new cluster terrestrial interface, purpose is in order to support the coexistence of LTE public network and cluster private network.
Step S608: terminal and cluster EPC carry out the NAS interacting message by eNB in the SRB1 carrying, indicate whether to carry out safety certification according to the NAS message content, activate cryptographic operation, the operation of UE capability query.These a few step operations are optional, judge whether to carry out these a few step flow processs by core net according to the NAS message that terminal sends.
Step S610: the NAS message content that cluster EPC sends according to terminal, judge to register and finish, initiate to discharge cluster RRC and connect.
Fig. 7 is the group service registering flow path schematic diagram based on the LTE technology of the present invention, below by an embodiment, comes step S604 is described in more detail to S610.
Step S604 launches, and is step S101 among Fig. 7 to S103, and flow process is consistent with the SRB Establishing process of standard LTE, and content comprises all the elements of standard LTE, but has increased the cluster relevant parameter, such as: the PLMN information of selection, the ID of group etc.
Step S606 launches, and is the step S201 among Fig. 7, sets up terrestrial interface and connects, and selects corresponding core network server, and initial UE message is carried out registration related information with UE request cluster core net.
Step S608 launches, and is step S301 to S312 and S401 to S403 among Fig. 7.In the SRB1 carrying, register inquiry cluster UE ability information by the NAS interacting message.
Terminal is by the registration request information in the cluster NAS message, the international mobile subscriber identity of carried terminal (International Mobile Subscriber Identification Number is referred to as IMSI) and lane place.Then the cluster core net is registered according to this message.
Step S301 to S308 interacting message among Fig. 7 just illustrates schematic diagram, is inaccurate to represent NAS interacting message number of times in the real process.Carry out as required safety certification and activate encryption flow, this link is optional flow process.Step S401 to S403 among Fig. 7 is cluster UE capability query flow process.ENB need to judge whether the UE capability query, such as needs, then carries out this process step operation, and this link is optional flow process.Step S309 to S312 among Fig. 7 is that flow process is finished in cluster core net and terminal check registration.So far, finish terminal and finish the registration content.Registration information all is to be carried by NAS message, because NAS message is transparent direct transferring to eNB, has realized end to end encryption, so that level security greatly improves.
Step S610 launches to be the step S501 among Fig. 7, after registering flow path is finished, and release flow process after the registration of beginning cluster is finished, notification terminal discharges, and discharges simultaneously the UE related resource configuration of eNB side.The normal scene of release after the release flow process of design is not only applicable to register and finishes herein also is applicable to user's context and sets up abnormality processing scene before, comprising: the registration refusal; The safety certification failure; Activate failed encryption; The inter-process that the cluster core net occurs when not setting up context is unusual; The inter-process that eNB occurs when not setting up context is unusual.
Finish normal scene or unusual scene if above-mentioned registration occurs, need this moment to send out to discharge.Below, further describe the release flow process in conjunction with Fig. 8.
The cluster core net is deleted first the core-network side Deta bearer.After finishing core-network side carrying release, next notify eNB to discharge the local resource allocation of eNB and interface-free resources, advice method has two kinds: (1) discharges by filling in indication field notice eNB in the cluster NAS message; (2) discharging Indication message notice eNB by UE discharges.
If the mode of taking (1) does not then have the step S601 among Fig. 8, eNB according to the NAS message parse indication field of the S301 in the prior figures 7 and S312 step, judges and will discharge, next carries out the step S701 among Fig. 8.
If the mode of taking (2) is then carried out first step S601 operation among Fig. 8, the cluster core net sends UE and discharges Indication message notice eNB release.It is the self-defined message that is different from UE context release message among the standard LTE that the UE here discharges Indication message.
ENB sends out cluster and send the release message of eating dishes without rice or wine, and such as the step S701 of Fig. 8, discharges cluster RRC and connects, and notice UE discharges the SRB carrying.Cluster RRC Connection Release flow process and standard LTE are similar, and related signaling adopts the self-defined message that is different from standard LTE agreement in the flow process.
Need explanation, the idle message among above Fig. 7 and Fig. 8 both can adopt standard LTE idle message, came the identification sets group business by the cluster parameter that expands in the message; Also can adopt self-defining cluster idle message to distinguish group service.The design of such message format, both can be compatible former LTE system also can realize clustering functionality flexibly.
Described by upper scheme, and compare with original technology, the present embodiment fully takes into account the particularity of trunking communication on the basis of original standard LTE system, and the access procedure of eating dishes without rice or wine is only set up the SRB1 carrying, then carry out NAS layer interacting message, namely discharge cluster after registration is finished and eat dishes without rice or wine to connect.Realize rapidity, the fail safe of registration, also avoided taking for a long time interface-free resources simultaneously, saved the channel resource expense of eating dishes without rice or wine.Also have, if carried out the operation of UE capability query in the enrollment process, just need not to inquire about again the UE ability information when then back UE accesses, shorten UE turn-on time.Such flow process realizes, has both followed now the gradually LTE standard of maturation, possesses simultaneously the independence of cluster.And the introducing of brand-new cluster terrestrial interface has no effect to the S1 interface of standard LTE, can easier realize LTE public network and the coexistence of cluster private network under a wireless system.In addition, the present embodiment is not distinguished time division duplex LTE or Frequency Division Duplexing (FDD) LTE, has compatible preferably.
