Before embodiments of the present invention are described, it first learns about and is moved to public network from only public network overlay area when terminal at present When with the overlay area of private network, terminal initiates the signalling interactive process in the registration process of cluster private network.

According to the process of prior art specification, terminal initiates the signalling interactive process in the registration process of cluster private network, such as Shown in Fig. 1, mainly comprise the steps that

Step 101: user equipment (UE, User Equipment) enters only long term evolution (LTE, Long Term Evolution) network's coverage area, initiates normal location registration procedure, source (Source) evolved base station (eNB, ENodeB) by the attach request of UE (attach request) message be transmitted to source (Source) mobility management entity (MME, Mobility Management Entity)；

Mutual authentication between step 102:Source MME and UE, examines the legitimacy of both sides；

Sessions carry is created between step 103:Source MME and Source gateway (GW, GateWay), is subsequent number Channel is provided according to transmission；

Step 104:Source MME receives the registration process of UE, sends attachment receiving (Attach Accept) to UE and disappears Breath, and request (Initial Context setup request) is established to Source eNB notice initial context, it needs ENB provides the empty port load-supporting of data transmission for UE；

After establishing the Deta bearer eated dishes without rice or wine between step 105:Source eNB and UE, UE completes attaching process, to (Attach complete) is completed in Source MME response registration；

So far, UE can provide normal EPS service for user.

Step 106: when UE is into the overlay area for existing simultaneously LTE and cluster private network in moving process, Source ENB perceives the change in location of UE by measurement report, sends switching request (Handover to target (Target) eNB first Request) message initiates handoff procedure to target area；

Step 107:Target MME perceive UE need to be reoriented to behind current coverage area and Target GW carry out Interaction, completes the sessions carry establishment process of target area；

Step 108:Target MME and Target eNB are interacted, and notice Target eNB provide the wireless money of the UE Source waits synchronizing process of the UE to target area；

Step 109:Target MME is forwarded to Source MME redirects response (Forward relocation Response) message；

Here, the purpose of this step is: target area is ready for completing the bearing resource of UE, and passes to Source MME。

Step 110:Source MME sends switching command (Handover Command) message and gives Source eNB, and by It notifies UE to open handoff procedure；

Here, it is the radio resource that terminal provides that target area is carried in Handover Command message.

Step 111:UE starts to detect synchronous Target cell, and notice Target eNB handoff procedure is completed after success, and UE is opened It opens and reads Target cell broadcast channel system information, perceive there is currently cluster network covering, initiate the registration process of cluster；

Step 112:UE and cluster network element interaction, complete cluster registration process.

Hereafter UE can carry out the communication process of group service.

From the above description, it will be seen that it is total from LTE network overlay area to enter cluster private network and LTE network in terminal With the scene of overlay area, terminal perceives cluster private network, and there are larger delays, cause cluster attachment delay to be initiated, affect cluster Business procedure.Meanwhile at present by terminal by reading network system information, registration is initiated again after perceiving the presence of cluster private network Process will cause the attach request that cluster core network element receives great amount of terminals in same amount of time, network be easy to cause to gather around Plug loads the drawbacks such as excessive.

Based on this, in various embodiments of the present invention: knowing that terminal is moved to the private network area of coverage from public network overlay area In domain and when needing to switch, the private network professional ability of the terminal of storage is sent to institute by corresponding first network element of the public network State corresponding second network element of private network；It is institute in the private network after second network element receives the private network professional ability of the terminal Terminal distribution service bearer resource is stated, and the registering result that third network element relevant to registration returns in receiving the private network Afterwards, the first network element of Xiang Suoshu returns to registering result；After first network element receives registering result, Xiang Suoshu terminal returns to registration knot Fruit；After the terminal receives registering result, the corresponding Target cell of the private network is synchronized.

Step 302: second network element is the terminal distribution service bearer resource in the private network, and described receiving After the registering result that third network element relevant to registration returns in private network, the first network element of Xiang Suoshu returns to registering result, so that institute It states the first network element and returns to registering result to the terminal.

Here, the third network element is different according to the difference of private network type.For example for, it is assumed that the private network is Cluster private network, then the third network element can be trunking dispatch server (PDS).

When the notice that second network element needs to relocate by the first network element terminal, the private network of the terminal is received When professional ability, second network element can return to registering result to first network element by redirecting the notice of result.

After the terminal receives registering result, the corresponding Target cell of the private network can be synchronized.

The present embodiment additionally provides a kind of method for realizing private network registration, as shown in figure 4, method includes the following steps:

Step 401: when knowing that terminal is moved in private network overlay area from public network overlay area and needs to switch, the public affairs It nets corresponding first network element and the private network professional ability of the terminal of storage is sent to corresponding second network element of the private network；

Here, first network element and second network element are the network element that user mobility is managed in network, for example For, in 3G network, first network element and second network element can be SGSN；In 4G network, first network element And second network element can be MME, at this point, common network can be EPS network, correspondingly, private network can be cluster private network.

Wherein, the terminal sends the private network professional ability of itself to first network element, specifically:

When the terminal is in the public network overlay area, the first network element of Xiang Suoshu sends public network Attach Request message；Institute State carrying private network login request message in public network Attach Request message.

In other words, the form of expression of the private network professional ability of the terminal may is that the terminal is in the public network The private network login request message carried in the public network attach request sent when overlay area.

Step 402: being the terminal in the private network after second network element receives the private network professional ability of the terminal Distribution business bearing resource, and after the registering result that third network element relevant to registration returns in receiving the private network, to institute It states the first network element and returns to registering result；

Embodiment two

On the basis of example 1, the present embodiment description evolution Universal Terrestrial wireless access network (EUTRAN, Evolved Universal Terrestrial Radio Access Network) under be rapidly completed EPS and cluster private network note The realization process of volume.As shown in figure 5, the process the following steps are included:

Step 501: mobile device UE booting resides in LTE network coverage area, and when current detection has clustering capability, Cluster registration request (Trunking Register is carried in EPS attach request (EPS Attach Request) message Request) message is notified to the Source eNB of current service network；

Here, current detection refers to clustering capability: when UE detects current support group service, at this point, UE can be simultaneously Trunking Register Request message is constructed, and the message code stream is carried in EPS Attach Request message In.

The EPS Attach Request message received is passed to the Source MME of current service by step 502:Source eNB, When Source MME detects that itself is not associated with corresponding cluster network element-PDS, Trunking Register is stored Request message is as UE ability information；Source MME continues EPS attaching process simultaneously, allows UE EPS to adhere to successfully, opens Normal EPS business, executes step 503 later；

Here, Source MME detect itself not with corresponding cluster network element-PDS be associated with, illustrate Source MME with Interface is not present between corresponding PDS.That is, when terminal is moved in the private network overlay area of corresponding PDS, Source The mobility of the not responsible management terminal of MME, needs to be implemented step 503~510, is responsible for the mobility of terminal by Target MME Management, to complete terminal in the registration process of cluster private network.

Trunking Register Request message refers to as UE ability information: Trunking Register The group service ability information that Request message is used as.

Here, after Source MME receives EPS Attach Request message, EPS attaching process can be made a response, I.e. attachment receives or attachment is refused.

EPS attaching process may include: that authentication ciphering, safe activation process and UE completion are mutually authenticated and establish Context information is the radio resource completed and foundation of carrying etc., and concrete processing procedure is same as the prior art, repeats no more.

After EPS adheres to successfully, Source MME can return to Attach Accept message to UE；UE receives Attach After Accept message, it will record EPS and adhere to successfully, cluster adheres to queued for log-on result phase.Hereafter, UE can be carried out normally EPS business.

After attachment refusal, according to the difference of attachment Reason For Denial, terminal can execute different treatment processes；After attachment refusal Treatment process it is same as the prior art, repeat no more.

Step 503:Source eNB perceives UE by the measurement report (Measure Report) of UE and is moved to cluster When private network coverage area, the handoff procedure of current UE is opened, notice Source MME starts repositioning process；

Here, Source eNB notifies Source MME to start weight by way of sending Handover Request message Position fixing process.

Step 504:Source MME forwards re-positioning request (Forward Relocation to Target MME Request) message；

Here, the cluster registration request of Source MME storage is carried in Forward Relocation Request message Message.

After step 505:Target MME network element receives Relocation Request message, therefrom extract in UE cluster Registration request, and it is sent to the cluster network element-PDS being associated；Target MME opens normal repositioning process simultaneously；

Here, normal repositioning process include: Target MME interacted with Target GW creation sessions carry, and with Radio bearer resources needed for Target eNB cross allocation UE.

After step 506:Target MME receives the reorientation result of PDS, Target GW and Target eNB, to Source MME sends Relocation Response message；

Here, the cluster registering result of PDS is carried in Relocation Response message.

After step 507:Source MME receives the Forward Relocation Response message of Target MME, Cluster registering result is extracted, and Source eNB is notified to open terminal switching process；

Here, Source MME is notified by way of sending Handover Command message to Source eNB Source eNB opens terminal switching process；Comprising PDS to the cluster registering result of the UE in Handover Command message.

Step 508:Source eNB sends Handover Command message to UE；

It here, include cluster registering result of the PDS to the UE in Handover Command message.

After step 509:UE receives the Handover Command message of Source eNB, target cluster therein is obtained The registering result of network element, and change cluster login state；

Here, after UE receives registering result, show that the registration of cluster private network has been completed.

Step 510: when succeeding in registration, the synchronous Target cell of UE can immediately begin to group service after the completion.

In other words, EPS and the registered success of cluster private network, can start the industry of corresponding types according to user demand Business.

Here, if when handover failure, that is, synchronization failure, UE can consider that the cluster private network registration of last time is still within waiting The registering result state that registering result state, i.e. record wait cluster private network, retract former cell, and UE still can continue at this time EPS business, and new cluster registering result is waited, to re-start the synchronization of Target cell；Meanwhile Source MME is still Storage cluster login request message code stream, the moving process for UE next time are prepared.

From the above description, it will be seen that registration scenarios provided in this embodiment, for EPS and clustering capability UE is stored by the way that the cluster registration message of UE to be stored in core network element as UE ability, when UE is from the only LTE network area of coverage When domain is moved in cluster private network overlay area, by the interactive process between normal network element, current UE is completed in object set The registration process of group's network element, and registering result is notified by handover request to UE, so that terminal fulfils cluster registration ahead of schedule As a result, that is to say, that end message can transmit between network element and quickly finish registration process.When terminal completes switching target It after cell process, does not need to complete cluster registration again through space interface signaling, to improve terminal cluster registration efficiency, shorten Terminal is moved to cluster network coverage area to the time delay for opening group service, and user experience is more preferable；And avoid a large amount of UE Space interface signaling interaction to same cluster network element, that is, avoiding cluster core network element interior in short-term may receive great amount of terminals registration Scene improves network security, and appearance situations such as avoid congestion.
