Embodiment

Central scope of the present invention is, Public Land Mobile Nerwork (the EPLMN of equity can be adopted in cut-over process, Equivalent Public Land Mobile Network) technology, restriction is by the international mobile subscriber identity (IMSI of the user in UNE according to himself, International MobileSubscriber Identification Number) access in batches and merge in objective network, wherein, the PLMN list (EPLMNLIST) of equity can be issued respectively to the user of different IMSI number sections by UNE, equivalent with notifying user equipment (UE) current network (namely by UNE) and Home PLMN (namely merging objective network), thus allow the user of different IMS I section access fusion objective network in batches, and merge the IMSI user of objective network for not accessing, then can be retained in original in UNE, thus solve in cut-over process can only the drawback of the number of pressing section process, realize seamless cutting.

Below in conjunction with drawings and the specific embodiments, technical solution of the present invention is described in further details,

Realize a cutover system for the network integration, comprise by UNE side apparatus and merge objective network side apparatus.

By UNE side apparatus, for sending reciprocity Public Land Mobile Nerwork (PLMN) list (EPLMN LIST) to its lower user, this EPLMN LIST comprises by the mark of UNE and the mark merging objective network, for notifying that subscriber installation arrives fusion objective network;

Wherein, by UNE side apparatus, the user to different international mobile subscriber identity (IMSI) number section sends described EPLMN LIST in batches.

Particularly, by UNE side apparatus, after sending EPLMN LIST to the user of same IMSI number section, also for the access authority of the user of this IMSI number section in the mobile switching centre of merging objective network is set to allow in access cutover lane place.

Merging objective network side apparatus, during for entering the cutover lane place of merging objective network the user receiving the EPLMNLIST issued by UNE side apparatus, receiving Client-initiated access request, and accept user and access fusion objective network;

Particularly, merge objective network side apparatus, when user enters the cutover lane place of merging objective network, also for issuing the EPLMN LIST included by UNE mark and UNE mark to these users, when then receiving Client-initiated access request, read the access authority of user, allow in access cutover lane place, then to accept user and access fusion objective network when read access right is limited to.

Introduce the process that said system realizes the network integration below in detail, in the present embodiment, in core net, network A needs to be fused to network B, and namely network A is by UNE, and network B is for merging objective network, and this process as shown in Figure 1, comprises the following steps:

Step 101: the network optimization is carried out to the wireless network and core net that merge objective network B;

Step 102: core-network side network element carries out operational trials and charging checking to fusion objective network B, wireless side network element carries out the network optimization operations such as all drive tests, to ensure that whole network possesses commercial condition to fusion objective network B;

Step 103: configure and met network integration requirement by UNE A and fusion objective network B;

In this step, operator will use for cutover for merging objective network B configuration network No., and for the network No. merging objective network B configuration be with by the PLMN of the network No. equity of UNE A, simultaneously, operator needs to know distribution, the users classification and variouss section online user number etc. of each IMSI number section in network A, during to ensure to carry out cutover by the IMSI number section of user, number of users is controlled;

The cutover condition of Carrier Requirements is met by every critical index (KPI) indexs such as the whole network drive test switching of UNE A and fusion objective network B or call drops;

Enter smoothly fast to allow user and merge objective network B, also will configure and be supported EPLMN function by the core net of UNE A, namely can issue EPLMNLIST to the user of the IMSI number section of specifying;

The IMSI that objective network B is merged in configuration limits roaming scenarios: namely at MSC (the MobileSwitching Center of network B, mobile switching centre) on corresponding roaming scenarios is configured to different IMSI number section users, this roaming scenarios comprises the band of position that user can access, come the access authority of limited subscriber on MSC and corresponding failed Reason For Denial value (wherein, failed Reason For Denial value can be selected according to the situation of reality, in the present embodiment, failure reason value is selected to be 13);

Wherein, need configuration to plan by the access authority of user the lane place scope (according to wireless coverage planning) that user can access at fusion objective network B, thus enable the normal access network B of user.

In cut-over process, namely cutover user non-in setting-up time is needed to refuse access and merges the user of objective network B when they attempt access fusion objective network B, the MSC merging objective network B sends suitable Reason For Denial value to it, so that user fast automaticly can return former network, allow user's unaware.

On MSC, the difference of the network No. of configuration network A and network B is as follows:

In network B, the lane place identification code (LAI) for rete mirabile number adopts Reason For Denial value to be: this lane place does not allow roaming;

In network B, Reason For Denial value is adopted to be for existing network with the LAI of network No.: this lane place exists unmatched community.

Define in area code (ZONECODE) the relevant configuration item of the MSC in network B, a ZONECODE can comprise one or more LAI.

Do not disturb existing network in this process, on using the user of existing network completely without impact.

After aforesaid operations completes, come into effect the scheme of enabling based on EPLMN and IMSI restriction and carry out cutover:

Step 104: select one or more IMSI number section, network A side apparatus (base station as network A) issues EPLMN LIST (comprising the PLMN of network A and network B) to the subscriber equipment of selected IMSI number section, to notify these users, network B and network A equity, and trigger these users and need access to merge objective network B;

After network A side apparatus gives EPLMN LIST to the user of certain one or more IMSI number section, the MSC of network B configures IMSI and changes roaming scenarios, that is, the access authority of the user of these IMSI number sections is set to allow access to merge the cutover position of objective network B;

Step 105: the operation repeating step 104, cutover each time all carries out fusion cutover, until issued EPLMN LIST to all users of network A by issuing EPLMN LIST to the user of the IMSI number section selected; Step 106: the user receiving EPLMN LIST enters merges objective network B, sends access request to fusion objective network B, merges the access request that objective network B receives these users;

Particularly, after the user receiving EPLMN LIST enters and merges objective network B, subject fusion network B side apparatus first issues EPLMN LIST (this EPLMN LIST comprises the PLMN of network A and network B) to these users, receive the EPLMN LIST user that subject fusion network B side apparatus issues and apply for access subject fusion network B, subject fusion network B side apparatus reads the access authority (namely reading roaming scenarios corresponding to this user from MSC) of this user in MSC, when the access right read is limited to permission access subject fusion network B, the base station of subject fusion network B sends EPLMN LIST to this user, this EPLMN LIST comprises by UNE A and the network No. merging objective network B, this user accesses merges objective network B,

Step 107: when after the large portion user cutover under network A to fusion objective network B (part have affect user can also continue to stay former network), carry out the cutover of last property, all remaining users are moved to network B;

In this step, after carrying out the cutover of last property, carry out network No. amendment, will be made into the network No. merging objective network B by the network No. of UNE A, the network of one or two different network No. of namely uniting is the network No. of network B, thus all users is attracted to fusion objective network B;

Step 108: observe a period of time to fusion objective network B, sees whether normal operation; If normal, then close by UNE A, otherwise need to refund, then return step 103.

Below in conjunction with Fig. 2, the detailed process of cutover is described, comprises the following steps:

Step 201: the wireless switching priority being arranged network B side apparatus (base transceiver station (BTS) or Node B (NODEB) as network B) by network management system is higher than by UNE A (when namely ensureing identical with the level signal merging objective network B by UNE A, user priority is selected to merge objective network B);

In this step, by the level parameters of the base transceiver station (BTS) or Node B (NODEB) that arrange network B, the priority that can ensure to merge objective network is higher than by UNE.

Step 202: in batches issued EPLMN LIST to subscriber equipment by the base station of UNE, comprises in this EPLMN LIST and to be identified and merge objective network B by UNE A and identify (being the network No. of network A and network B in the present embodiment);

Needed to issue EPLMN LIST to the IMSI of cutover by UNE (i.e. former network), with notify user by UNE and merge objective network for peer-to-peer network, and notify user access fast merge objective network (namely new network).

Step 203: the access authority of these users in the MSC of objective network is merged in amendment;

In this step, user's (namely having been issued the user of EPLMN LIST by UNE) of the specific IMSI number section of this secondary cutover is configured in the IMSI roaming scenarios on the MSC merging objective network (this IMSI roaming scenarios is what set in advance), namely allows these users to access in the lane place of cutover.

Step 204: when the user of the specific IMSI number section of this secondary cutover enters fusion objective network B, merge objective network B and issue EPLMN LIST (this EPLMN LIST includes the PLMN of network A and network B) to these users;

In this step, merge objective network B side and tell that subscriber equipment (UE) current network and Home PLMN are equivalent by reciprocity PLMN list (EPLMN LIST), allow user can the resource of oneself other communication network of Selection utilization for he provides service, user-selected network should be the reciprocity PLMN network be kept in user identification module (SIM) in the EPLMN list that user opens an account or operator provides for him in the process of location updating.Otherwise subscriber equipment can do gravity treatment to Home Public Land Mobile Network HPLMN, returns to former network.

This step is only the guarantee step in cutover step, returns the cell reselection of former network and inter-network number after being used for ensureing cutover abnormal relief user gravity treatment; This step is not as the necessary condition of user access network B.In other application scenarioss, this step can also operate with step 205 simultaneously.

Step 205: this cutover user applies for that objective network B is merged in access, and after confirmation has access authority access network B;

Step 206: operational trials and charging checking are carried out to fusion objective network B, again ensures the normal of business;

In other scenes, as long as carry out the operation of this step before this cutover user formally accesses fusion objective network B, such as, after step 207, then the operation of this step can be performed.

Step 207: network equipment (such as, base station in network B) calling party location register (VLR) with check and observe application access cutover user, refund the need of the carrying out of refunding former network, if, then this user is backed former network (i.e. network A), otherwise accept applications, this user incorporates network B.

Check calling party location register (VLR) user, all successful cutover of all users is to new network, and user can merge objective network B from being moved to by UNE A successfully automatically generally in 12 hours.

Because rete mirabile problem may cause some mobile phone to occur abnormal phenomenon or the user important to some, therefore, need these to be occurred abnormality or some important user are as last batch of, like this when each selection until IMSI number section belonging to cutover user, these users must be separated from the IMSI number section belonging to it, namely EPLMN LIST is not issued to it, allow them continue to stay existing network.Particularly, can use the signing access restriction of HLR before cutover, attempt access fusion objective network B to refuse these users, now, these users are by former for auto-returned network.

Wherein, complaint during in order to further prevent cutover or after cutover, needs to take corresponding counter-measure: be divided into two kinds of situations, and a kind of is know before cutover to need to refund, and another kind complains after cutover to need to refund.

For knowing before cutover that needs refund, concrete process is as follows: the scheme adopting HLR Access Restriction Data, namely user to contract Access Restriction Data at HLR, if user attempts access merge objective network B, is kicked back by UNE by Access Restriction Data refusal.Because these need the possibility of the IMSI belonging to refusal user discontinuous, so adopt the contract mode of Access Restriction Data of HLR to contract to these users before cutover, and subscription data is inserted VLR, the Reason For Denial value that MSC side adopts can be: PLMN does not allow (PLMN NOT ALLOWED).And HLR can carry out lower slotting Access Restriction Data according to VLR Global Title (GT), only insert new MSC/VLR, do not insert former network, avoid having an impact to former network, such as Anchor MSC cannot normal process Access Restriction Data etc.Like this, the user of these refusals attempts access merges objective network B, can be refused by the unallowed cause value of PLMN, and the former network of auto-returned, again attempt the network No. merging objective network never again.

If need to refund former network for existing after cutover to complain, also can adopting the signing access restriction of above-mentioned HLR, after trigger position again more new technological process refusal, getting back to original in UNE A from merging objective network B.Concrete process is as follows: by above-mentioned method, to contract Access Restriction Data in hlr these users, such user next time business time or after the periodic location update time arrives, again trigger position is more after new technological process refusal, and user can get back to original in UNE A from merging objective network B again.When after the large-area complaint of appearance, the directly base station of restriction fusion objective network B, user can switchback immediately original by UNE A, continue to enjoy customer service, even if the calling of conversing also can not dropped call, and then reach the object of refunding fast.

As can be seen from above-described embodiment, technical solution of the present invention carries out the network optimization in advance to two nets, ensures to have reached high-quality commercial network state before two nets merge, thus ensures that two nets merge the performance of overall network after cutovers; Owing to having had comprehensive grasp to the IMSI of two network users and mobile phone terminal type distributes before cutover, when cutover, optionally will issue EPLMNLIST to specific user type, ensure that cutover test user or low-end subscribers on a small quantity in early stage, and latter stage is carried out fusion cutover in the cutover after fully verifying by high-end user; In addition, due to during whole cutover, two network users can not produce service disconnection and other influences, therefore can not perceive two nets and merge the service disconnection or other promptings (as abnormal roaming) brought.

Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as the protection range belonging to claims of the present invention.
