Description

The implementation method that a kind of nomadism number in multiple district number net-building mode distributes

Technical field

The present invention relates to field of mobile communication, the method that Mobile Station Roaming Number MSRN in the particularly third generation mobile system (Mobile Station Roaming Number) distributes expansion and uses.

Background technology

MSC/VLR (MSC Mobile services Switching Center, Mobile Switching Center mobile switching centre; VLR Visitor Location Register VLR Visitor Location Register) be one of core network element of cell mobile communication systems, it is all to be positioned at its user of mobile station that covers long-distance zone control and finish professional functional entity.

The characteristics of mobile communcations system are that the user can roam.When the mobile subscriber when called, this user visiting ground VLR can distribute a number for the user is interim, so that gateway exchange GMSC/VLR (GMSC Gateway Mobile-servicesSwitching Center Gateway Mobile Switching Center) can route calls to this user's visit ground MSC/VLR.This interim number that distributes is exactly a roaming number.Mobile subscriber's route information inquiry and provide process when called referring to accompanying drawing 1, detailed process is as follows:

1. gateway exchange is received initialization address message IAM (Initial Address Message);

2. gateway exchange is by attaching position register HLR (Home Location Register) the inquiry routing iinformation of MAP MAP (Mobile Application Part) under the user;

3.HLR send the request of Providing Roaming Number to VLR according to called subscriber place VLR information;

4.VLR the distribution roaming number returns roaming number and gives HLR;

5.HLR return called subscriber's routing iinformation to gateway exchange;

6. gateway exchange sends to VMSCS/VLR according to routing iinformation with IAM message.

Consisting of of roaming number: CC+NDC+M1M2M3+ABC.Usually claim that CC+NDC+M1M2M3 is the roaming number prefix, ABC is casual user's number.

Under the present circumstances, the MSC/VLR capacity is less, only covers a long-distance zone.The distribution method of roaming number is: for MSC/VLR distributes a roaming number prefix; After receiving the roaming number request for allocation, VLR is according to the roaming number resource acquisition roaming number dynamic bit of free time; Form roaming number according to roaming number prefix and roaming number dynamic bit.Because MSC/VRL only covers a long-distance zone, so has one-to-one relationship between roaming number prefix and the long-distance zone.

But after the 3G (Third Generation) Moblie R4 stage, the Capacity Ratio of MSC/VLR is bigger, can cover a plurality of long-distance zones, and energy while tape base station control BSC and radio network controller (RNC) (BSC Base Station Controller; RNC Radio Network Controller), promptly the R4 stage need be realized the Multiple Area Code Function networking mode, and the Multiple Area Code Function networking mode of big capacity MSC/VLR is seen accompanying drawing 2.But the roaming number prefix of MSC/VLR correspondence has only one, the relation in roaming number prefix and long-distance zone becomes the relation of one-to-many, can't know long-distance zone, the actual place of user according to the roaming number that same MSC/VLR distributes, also just can't know whether the user is the roamer under same MSC/VLR according to roaming number.

If will realize knowing long-distance zone, the actual place of user according to roaming number under the Multiple Area Code Function networking mode, and judge whether the user roams, just need to solve the defective of " the only corresponding roaming number prefix of the next MSC/VLR of Multiple Area Code Function networking mode can not be distinguished a plurality of long-distance zones by the roaming number prefix ".

Summary of the invention

Technical problem to be solved by this invention provides the roaming number distribution method of supporting a plurality of roaming number prefixes when the next MSC/VLR of a kind of Multiple Area Code Function networking mode covers a plurality of long-distance zone, to overcome the only corresponding roaming number prefix of the next MSC/VLR of Multiple Area Code Function networking mode, can not distinguish the defective in a plurality of long-distance zones by roaming number.

The next MSC/VLR of a kind of Multiple Area Code Function networking mode of the present invention supports the roaming number distribution method of a plurality of roaming number prefixes when covering a plurality of long-distance zone, this method may further comprise the steps:

1. divide virtual MSC/VLR, comprise:

1.1 virtual MSC of each long-distance region allocation/VLR index for the MSC/VLR covering;

1.2 be each virtual MSC/roaming number prefix of VLR index assignment;

2. support the roaming number of a plurality of roaming number prefixes to distribute, comprise:

2.1VLR receive the request of Providing Roaming Number of HLR;

2.2VLR obtain the RNC/BSC office direction numbering of the current access of user;

2.3VLR obtain virtual MSC/VLR index according to RNC/BSC office direction numbering;

2.4VLR, obtain roaming number prefix and number section according to virtual MSC/VLR index;

2.5VLR distribute a roaming number according to roaming number prefix and number section, sending to HLR provides the roaming response;

3. the allocation manager of user's temporary number ABC comprises:

3.1 ABC is deposited into the roaming number idle queues with user's temporary number;

3.2 obtain user's temporary number ABC from the roaming number idle queues when distributing roaming number;

3.3 when discharging roaming number user's temporary number ABC is inserted the roaming number idle queues.

Adopt the beneficial effect of technical solution of the present invention to be: under the Multiple Area Code Function networking mode, can obtain the long-distance zone at user place by roaming number.And can by under long-distance zone under the user and the roaming number whether whether the consistent user of judgement is the roamer.
