Description
Technical field
The present invention relates to moving communicating field, particularly relate to the place of a kind of mobile number carrying service
Reason method.
Background technology
In order to preferably utilize Internet resources, promote rationally competition.At present, a lot of standardization group
Knitting the relevant criterion all having formulated mobile number portability (MNP), various countries' Mobile Communications Market is also
Introduce mobile number carrying service one after another.
In 3G, mobile number carrying service is mainly by 3GPP 22.066 and 3GPP 23.066 agreement
Specification defines, and GSM (Global System for Mobile Communications, move by the whole world
Dynamic communication system) the local number portability implementation of network is substantially identical with this.According to agreement
Describing, MNP function includes SRF (signalling relay function) mode and IN mode.SRF side
Formula uses MAP related signaling as realizing the basic means of MNP, and IN mode uses intelligence
Network information mode is as the basic means of MNP.
For SRF mode, agreement describe GMSC (mobile gateway switching centre) network element,
MNP-SRF/MATF (MAP application Terminating Function, Mobile solution
Termination function) and NPDB (number portability database), merge and be referred to as MNP-SRF/NPDB
(supporting the signalling relay function/number portability database of MNP) equipment, HLR (ownership position
Put depositor) interface relationship between the relevant device such as network element, working method.Including should carry out
Operating procedure, signaling process etc. problem, solve user in mobile communications network well
Local number portability problem.
After there is number portability service, called subscriber may turn net, is not this network users
, at this moment, HLR just cannot inform the called roaming number of GMSC, and GMSC just cannot
Carry out call routing, thus affect calling normal continuance.By introducing number portability database
NPDB (number portability database), can solve this problem smoothly.NPDB deposits
The home network information of all users, by inquiry NPDB it is known that user currently returns
Belonging to which network, during calling, this inquires about called subscriber's roaming number to the HLR of which network.
When certain user occurs number portability service, the NPDB of removal network revises data and joins
Put, this network users (or carrying access customer) change this User Status into his network users, and remember
Record this user and move into the routing number RN of network；Meanwhile, the NPDB moving into network also revises
Data configuration, is changed this User Status into this network users (or carrying access customer) by his network users.
Here RN refers to Routing Number routing number, is used to refer to belonging to user's reality
Network, during call routing use.
Under normal conditions, the handshaking procedure of calling is: after receiving and calling for asking, GMSC to
HLR sends SRI (route requests) message, inquires about called routing iinformation, and HLR is to VLR
Inquire about called position, obtain called roaming number, then by SRI_ACK (route
Request response) return called roaming number to GMSC, GMSC is accordingly by call routing
Call proceeding is completed to corresponding VMSC (visit mobile gateway switch).
The signaling message that SRF mode relates to specifically includes that
SRI:Send Routeing Information sends route requests；
SRI-ACK:Send Routeing Information acknowledge sends route requests
Response；
IAM:Initial Address Message initial address message.
Briefly the MNP operation principle of SRF mode is exactly:
Receiving after calling for asking, GMSC is not directly to send SRI information query quilt to HLR
It is the routing iinformation of user, but first sends SRI message to MNP-SRF/NPDB,
NPDB inquires about the current home network information of called subscriber, carries out next according to Query Result
Step.
If this network users, then the whole process called is as it is shown in figure 1, include:
101, rise exhale switch send carry called subscriber MSISDN (The Mobile Station
ISDN number, mobile station comprehensive service digital net number) IAM message to GMSC B；
102, the SRI that GMSC B carries MSISDN to MNP-SRF/NPDB transmission disappears
Breath；
103, in NPDB, inquire about the current home network information of called subscriber, determine called
User is this network users；MNP-SRF/NPDB routes the call to the HLR B of user attaching；
104, the routing iinformation that HLR B inquiry is called, by SRI-ACK message, directly returns
Return the roaming number MSRN of called subscriber to GMSC B；
105, GMSC B routes the call to VMSC B accordingly；
106, VMSC B completes call proceeding, calling to called subscriber MS (mobile station) B.
If called subscriber is for having occurred and that local number portability, turn the net user to other networks, then
The whole process of calling is as in figure 2 it is shown, include:
201, calling subscribe MS A rises and exhales VMSC A；
202, VMSC A send carry the IAM message of called subscriber's Mobile Subscriber International ISDN Number to
GMSC A；
203, the SRI that GMSC A carries MSISDN to MNP-SRF/NPDB transmission disappears
Breath；
204, MNP-SRF/NPDB inquires about the current home network of called subscriber in NPDB
Information, determines that called subscriber, for having occurred and that local number portability, turns the net user to other networks；
MNP-SRF/NPDB returns SRI_ACK message to GMSC A, including called use
The routing number RN of place, family network and Mobile Subscriber International ISDN Number；
205, the road of the user place network that GMSC A returns according to MNP-SRF/NPDB
By number RN, send IAM message and route the call to called place network G MSC B, its
Middle called number is RN+MSISDN；
206, the SRI that GMSC B carries MSISDN to MNP-SRF/NPDB transmission disappears
Breath, inquires about the current home network information of called subscriber in NPDB, determines that called subscriber is
This network users；
207, MNP-SRF/NPDB routes the call to the HLR of user attaching；
208, the routing iinformation that HLR inquiry is called, by SRI-ACK message, directly returns
Return called roaming number to GMSC B；
209, GMSC B routes the call to end office (EO) accordingly, end office (EO) complete call proceeding.
The correlation function of the supplementary service of mobile communications network, institute cannot be realized due to IN mode
With, all use SRF mode when general mobile communications network introduces number portability service,
The thinking of prevention message loop and SRF also basic simlarity, be the most just not repeated IN mode
Describe.
Prior art there is the problem that
When implementing mobile number portability, relate to be moved in and out two mobile networks, two
Individual different mobile number portability data base (MNP-SRF/NPDB), needs to remove network
NPDB revises data configuration, by this User Status by this network users (or carrying access customer)
Change his network users into, and record this user and move into the routing number RN of network；Meanwhile, move into
The NPDB of network also revises data configuration, his network users change this User Status into Home Network and use
Family (or carrying access customer).
Data collocation error it is likely to occur: i.e. remove network in this operating process
Data in NPDB are that this user has moved out, and are his network users；And move into the number in network
According to not amendment, remain in that this user is original record of his network users.
So, the NPDB of two networks thinks that this user is the user of bipartite network, is exhaling
When crying generation, the NPDB of two networks can return with bipartite network RN to GMSC
SRI-ACK message, GMSC accordingly will be repeatedly by secondary call routing to bipartite network, shape
One-tenth message loop, continuous consumption of network resources, as it is shown on figure 3, calling procedure includes:
301, calling subscribe MS A rises and exhales VMSC A；
302, VIMC A send carry the IAM message of called subscriber's Mobile Subscriber International ISDN Number to
GMSC A；
303, the SRI that GMSC A carries MSISDN to MNP-SRF/NPDB transmission disappears
Breath；
304, MNP-SRF/NPDB inquires about the current home network of called subscriber in NPDB
Information, determines that called subscriber, for having occurred and that local number portability, turns the net user to other networks；
MNP-SRF/NPDB returns SRI_ACK message to GMSC A, including called use
The routing number RN (sensing is carried into network) of place, family network and Mobile Subscriber International ISDN Number；
305, the user routing number RN that GMSC A returns according to MNP-SRF/NPDB,
Send IAM message and route the call to called place network G MSC B, wherein called number
For RN+ MSISDN；
306, the SRI that GMSC B carries MSISDN to MNP-SRF/NPDB transmission disappears
Breath, inquires about the current home network information of called subscriber in NPDB, determines that called subscriber is non-
This network users；
307, MNP-SRF/NPDB returns SRI-ACK message to GMSC B, in message
Carry RN (sensing carries out network) and the Mobile Subscriber International ISDN Number at called subscriber place；
308, the user routing number RN that GMSC B returns according to MNP-SRF/NPDB,
Route the call to called place network G MSCA.
Visible, owing to NPDB data configuration is incorrect, system will repeat always step 303～
308, form message loop.
In order to prevent such phenomenon from occurring, agreement defines the side of a prevention message route
Method: in the XUDT (units of enhancing of signaling SCCP (connect and control part) layer protocol
According to message) in, hop counter parameter is set, not through this network element once, XUDT's message disappears
Hop counter in breath just subtracts one, and when jumping technology device and being 0, message is dropped.
But, this method has two serious defects:
(1) when general call routing inquiry SRI, use is all UDT (units
According to message), XUDT message will not be used, and UDT message is not have hop counter parameter
's.If the most current message related to calls flow process is not revised, by using UDT
Message changes into using XUDT message, then, this method is actual cannot be used；
(2) even if now current message related to calls flow process to be made the revision described in (1),
So before the hop counter value waiting XUDT message reduces to 0, still can produce repeatedly
Message loop between two mobile networks, it means that can produce between two Mobile Network Operator
Raw multiple unnecessary interworking between network message, produce unnecessary closing the account, and increase operator
Operating cost.
