Detailed description of the invention

Below in conjunction with the accompanying drawings and the present invention is described in further detail by embodiment again.

Before embodiments of the present invention are described, first learn about at present when terminal moves from only public network overlay area During to the overlay area of public network and 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 exchange mistake in the registration process of cluster private network Journey, as it is shown in figure 1, mainly comprise the steps that

Step 101: subscriber equipment (UE, User Equipment) enters only Long Term Evolution (LTE, Long Term Evolution) network's coverage area, initiate normal location registration procedure, source (Source) evolution The attachment of UE is asked (attach request) message to pass to source (Source) by type base station (eNB, eNodeB) Mobility Management Entity (MME, Mobility Management Entity)；

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

Create session between step 103:Source MME and Source gateway (GW, GateWay) to hold Carry, provide passage for follow-up data transmission；

Step 104:Source MME accepts the registration process of UE, sends attachment to UE and accepts (Attach Accept) message, and set up request (Initial Context setup to Source eNB notice initial context Request), eNB is needed to provide the empty port load-supporting of data transmission for UE；

After setting up, between step 105:Source eNB and UE, the Deta bearer eated dishes without rice or wine, UE completes to adhere to Journey, completes (Attach complete) to Source MME response registration；

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

Step 106: when UE moving process in the overlay area that there is LTE and cluster private network simultaneously In, the Source eNB change in location by measurement report perception UE, first to target (Target) eNB Send handover request (Handover request) message, initiate handoff procedure to target area；

Step 107:Target MME perceives after UE needs to be reoriented to current coverage area, and Target GW interacts, and the sessions carry completing target area sets up process；

Step 108:Target MME and Target eNB interacts, and notice Target eNB provides should The Radio Resource of UE, waits the UE synchronizing process to target area；

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

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

Step 110:Source MME sends switching command (Handover Command) message to Source ENB, and notified that UE opens handoff procedure by it；

Here, Handover Command message carries the Radio Resource that target area provides for terminal.

Step 111:UE starts detection and synchronizes Target cell, notifies that Target eNB handoff procedure is complete after success Becoming, UE opens and reads Target cell broadcast channel system information, perceives and there is currently cluster network covering, Initiate the registration process of cluster；

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

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

From the above description, it will be seen that terminal from LTE network overlay area enter cluster private network and LTE network collectively covers the scene in region, and terminal perception cluster private network exists bigger delay, causes cluster attached Delay to initiate, have impact on group service process.Meanwhile, at present by terminal by reading network system information, Initiate the process of registration after the existence of perception cluster private network again, cluster core network element can be caused at same amount of time Inside receive the attachment request of great amount of terminals, easily cause the network congestion loads drawback such as too much.

Here, described 3rd network element is different according to the difference of private network type.For giving an example, it is assumed that institute Stating private network is cluster private network, and the most described 3rd network element can be trunking dispatch server (PDS).

When described second network element needs the notice of reorientation by described first network element terminal, receive described terminal Private network professional ability time, described second network element can by redirect result notice to described first network element Return registering result.

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

The present embodiment additionally provide a kind of realize private network registration method, as shown in Figure 4, the method include with Lower step:

Step 401: know when terminal moves to private network overlay area from public network overlay area and needs switching, The private network professional ability of the described terminal of storage is sent to described private network pair by the first network element that described public network is corresponding The second network element answered；

Here, described first network element and described second network element are the network element managing user mobility in network, lift For individual example, in 3G network, described first network element and described second network element can be SGSN；? In 4G network, described first network element and described second network element can be MME, and now, common network can be EPS Network, correspondingly, private network can be cluster private network.

Wherein, described terminal sends the private network professional ability of self to described first network element, particularly as follows:

Described end, when described public network overlay area, sends public network attachment request to described first network element and disappears Breath；Described public network Attach Request message carries private network login request message.

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

Step 402: after described second network element receives the private network professional ability of described terminal, at described private network be Described terminal distribution service bearer resource, and the 3rd network element return relevant to registration in receiving described private network Registering result after, to described first network element return registering result；

Embodiment two

On the basis of embodiment one, the present embodiment is described in the Universal Terrestrial wireless access network of evolution It is rapidly completed under (EUTRAN, Evolved Universal Terrestrial Radio Access Network) What EPS and cluster private network were registered realizes process.As it is shown in figure 5, this process comprises the following steps:

Step 501: the start of mobile device UE resides in LTE network coverage, and current detection has During clustering capability, carrying cluster registration in EPS attachment request (EPS Attach Request) message please Seek (Trunking Register Request) message, notify to the Source eNB of current service network；

Here, current detection has clustering capability and refers to: currently support group service when UE detects, now, UE can construct Trunking Register Request message simultaneously, and carries this message code stream at EPS In Attach Request message.

The EPS Attach Request message received is passed to the Source of current service by step 502:Source eNB MME, Source MME detects when self does not associate with corresponding cluster network element-PDS, storage Trunking Register Request message is as UE ability information；Source MME continues EPS simultaneously Attaching process, allows UE EPS adhere to successfully, opens normal EPS business, performs step 503 afterwards；

Here, Source MME detects self and does not associate with corresponding cluster network element-PDS, and Source is described Interface is there is not between MME and corresponding PDS.It is to say, when terminal moves to the special of corresponding PDS Time in net overlay area, the mobility of Source MME not responsible management terminal, need to perform step 503～510, Target MME it is responsible for the mobile management of terminal, thus completes terminal at cluster private network Registration process.

Trunking Register Request message, as UE ability information, refers to: Trunking Register Request message as group service ability information.

Here, after Source MME receives EPS Attach Request message, can be to EPS attaching process Respond, i.e. attachment accepts or attachment refusal.

EPS attaching process may include that authentication ciphering, safe activation process complete to be mutually authenticated with UE And setting up Radio Resource and the foundation etc. of carrying that contextual information i.e. completes, concrete processing procedure is with existing Technology is identical, repeats no more.

After EPS adheres to successfully, Source MME can return Attach Accept message to UE；UE receives After Attach Accept message, EPS can be recorded and adhere to successfully, cluster attachment queued for log-on result phase.Hereafter, UE can carry out normal EPS business.

After attachment refusal, according to the difference of attachment Reason For Denial, terminal can perform different processing procedures；Attached The processing procedure after refusal same as the prior art, repeat no more.

Step 503:Source eNB perceives UE by the measurement report (Measure Report) of UE When moving to cluster private network coverage area, open the handoff procedure of current UE, notify Source MME Start repositioning process；

Here, Source eNB notifies Source MME by the way of sending Handover Request message Start repositioning process.

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

Here, Forward Relocation Request message is carried the cluster note of Source MME storage Volume request message.

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

Here, normal repositioning process includes: Target MME and Target GW creates session alternately and holds Carry, and with Target eNB cross allocation UE needed for radio bearer resources.

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

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

Step 507:Source MME receives the Forward Relocation Response of Target MME After message, extract cluster registering result, and notify that Source eNB opens terminal switching process；

Here, Source MME by sending the side of Handover Command message to Source eNB Formula notice Source eNB opens terminal switching process；Handover Command message comprises PDS pair The cluster registering result of this UE.

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

Here, Handover Command message comprises the PDS cluster registering result to this UE.

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

Here, after UE receives registering result, show that the registration of cluster private network is complete.

Step 510: when succeeding in registration, UE synchronizes Target cell, can immediately begin to cluster industry after completing Business.

In other words, EPS and the most registered success of cluster private network, correspondence can be started according to user's request The business of type.

Here, if during the i.e. synchronization failure of handoff failure, UE is it is believed that the registration of the cluster private network of last time is still located In queued for log-on result phase, i.e. record waits the registering result state of cluster private network, the former community of rollback, this Time UE still can continue EPS business, and wait new cluster registering result, in order to re-start target The synchronization of community；Meanwhile, Source MME still storage cluster login request message code stream, for next time The moving process of UE is prepared.
