Description
Technical field
The present invention relates to a kind of system and method for realizing that the subscriber directory number inter-network is used, exactly, relate to a kind of system and method that uses based on user attaching register HLR realization subscriber directory number inter-network, belong to the technical field of telephone communication network.
Background technology
In order to realize number portability, the telephone number mixed number allocation service in the telephone network, need distribute two numbers for the user: logical number and physical number, logical number is Subscriber Number DN (DirectoryNumber)-be the one number that operator distributes to the user again, also be that the user discerns the number that the user also charges to number and the operator that the external world announces, as user's sign; Physical number is routing number LRN (Location Routing Number)-be that the user attaching network is the user terminal assigned access number again, it also is the routing number that switching equipment is sought the true place of user terminal, be the routing number that network internal is used, this number is not announced to the external world.In fixed-line telephone network, physical number is that user terminal inserts the pairing number of physical location, and it is corresponding with certain port or subscribers feeder in the fixed network switch, and the local network switching equipment is according to this number addressing user's true place; In Personal Handyphone System(PHS) and mobile phone, this physical number then is counted as the actual access code that network distributes for the user, i.e. mobile roaming number.All be provided with in each telephone network and be used to realize continue the network element device changed between above-mentioned two numbers according to called physical number to guarantee to call out, and to the logical number of called display of calling.
Say that exactly " number portability " is meant that physical number changes and the immovable business of logical number, " mixed number allocation service " is meant that the user chooses at random the business of logical number under the constant situation of physical number.The common trait of these two business is that user's logical number and physical number do not have fixing binding relationship, and two kinds of numbers can adopt different coding rules respectively, also can belong to different networks or operator.In general, number portability business can be applicable to dissimilar telephone networks such as fixed network, mobile network, and mixed number allocation service can only be applied to fixed-line telephone network.
The key that realizes number portability business and mixed number allocation service is how to realize telephone subscriber's the logical number and the mutual conversion of physical number.For the business of in consolidated network, carrying out, can utilize the user attaching register HLR (Home Location Register) of user data in the centralized stores net to realize the conversion of logical number and physical number.Number portability and mixed number allocation service for across a network, the situation that promptly belongs to heterogeneous networks respectively for logical number and physical number, present solution is to introduce the number portability data-base NPDB that inter-network is disposed, do when called the user, when calling routes to logical number home network exchange office point, exchange is obtained called physical number by inquiry NPDB, directly routes the call to the called subscriber according to this physical number again.The advantage of this method is to have avoided alternative channel, but has the following disadvantages:
(1) needs to introduce new network element in the network, not only will transform, also will increase many protocol interfaces, implement more complicated existing network.
(2) because fixed network is not supported the visit to NPDB, so such scheme is only applicable to the number portability service between the different mobile networks at present.And how the fixed network number realizes that the problem that across a network uses is the difficult problem that current fixed network operator faces, and also is professional focus and focus that the telecom technology personnel research and develop the selected topic.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of system and method that uses based on user attaching register HLR realization subscriber directory number inter-network, this system and method is not only applicable to the inter-network of mobile number and uses, and is applicable to that the inter-network of fixed network number is used yet.And, the fully compatible existing network architecture of system of the present invention based on home location register HLR, need not to increase new network element and change original protocol interface, also need not to transform other network element devices, simple in structure, the workload of the network rebuilding seldom realizes easily, can be applicable to various heterogeneous networks such as fixed-line phone network, fixed wireless network, mobile telephone network simultaneously, have good popularization and application prospect.
