Abstract
This invention discloses a method that NASS access to the network location through CLF information; it belongs to the next generation of mobile communications network technology. It is brought out to settle the problems and the shortcomings when users in the network visit Victoria, domain ownership's conversation positioning and connecting storage functionality is entity denied access to the user's network location information. In this invention the NASS pass through CLF access to the get network location information, in next generation of mobile's network-wide have an unified distribution network identifier, and in the operational control subsystem and business application layer it makes additional users' domain identifier which the connect conversation positioning and storage functions of this entity network users access to positioning information request. The stated operational control subsystems and business application layer get Network operators positioning information through the domain identifier's linking conversation positioning and storage functional entities. The invention will enable operational control subsystems and business application layer convenient and efficient to get the network user positioning information.
Description
Technical field
The present invention relates to next generation network (NGN, Next Generation Network) mobile communication technology field, relate in particular in the NGN architectural framework, professional control subsystem and service application layer (SCSA, ServiceControl Subsystems and Applications) obtain the method for user's network positioning information (Network LocationInformation).
Background technology
At present, with the Internet new technology of representative just conventional telecommunication network in profound influence notion and system, next generation network is one of wherein the most noticeable bright spot.In current a kind of NGN architectural framework, the major function of Network Attachment Subsystem as depicted in figs. 1 and 2 (NASS, Network Attachment Subsystem) be dynamic assignment Internet Protocol (IP) address and other-end configuration parameter, during the IP address assignment program or before occur in IP layer user's authentication and authentication, according to the network insertion mandate of customer service inventory (Profile), according to the Access Network configuration of customer service inventory (Profile), occur in the location management of IP layer etc.
In numerous functional entitys that NASS comprises, connection session location and memory function entity (CLF, Connectivity Session Location and Repository Function) ustomer premises access equipment (CPE is distributed in registration, Customer Premises Equipment) IP address and by network access configuration function entity (NACF, Network Access Configuration Function) contact between the network positioning information that provides, as insert transmission equipment characteristic (Access Transport Equipment Characteristics), linear identifier (LineIdentifier (Logical Access ID)), IP limit end identifier (IP Edge Identity) etc., contact between network positioning information and the geo-localisation information.In addition, CLF also memory allocation IP address user identifier, user network service quality (QoS, Quality of Service) describe and with the relevant customer parameter of the privately owned locating information of user.
SCSA can be by the network positioning information of CLF inquiring user.After CLF receives the request of obtaining the user network locating information that professional control subsystem and service application layer send, the network positioning information of response such as user identifier (Subscriber ID), locating information (Location Information), resource and accommodation control subsystem tie point (RACS Contact Point), terminal type (Terminal Type), access network type (AccessNetwork Type), application system are bound (Applications Bundling) etc. be sent to SCSA.
In current NASS, if the user is in the home domain (Home Network) of network, SCSA will obtain this user's network positioning information, then by the interface between SCSA and the CLF, CLF to home domain sends the network positioning information request of obtaining the user, CLF just can obtain the network positioning information that it wants the user that obtains by other interface in its home domain network after receiving the network positioning information request.
But, if the user is not at the home domain of network, but be in the visit territory (Visit Network) of network, the CLF of its home domain is after the network positioning information request of receiving SCSA, because the CLF of home domain can't be known the position in user's visit of living in territory by the parameter in the present information, therefore can not precedingly change the CLF of solicited message, promptly can't obtain the network positioning information request that is in the user who visits the territory by the CLF in visit territory to visit territory, user place.
Summary of the invention
The objective of the invention is to solve the user when being in the visit territory of network, the CLF of home domain can not obtain this user's the existing problem and shortage of network positioning information, a kind of convenience is provided, obtains the method for network positioning information among the NASS by CLF efficiently.
For addressing the above problem, the present invention adopts following technical scheme: the method that obtains network positioning information among this NASS by CLF, in the network-wide basis of next generation network, distribute network identifier unitedly, and in the request of obtaining the user network locating information that professional control subsystem and service application course connection session location and memory function entity send, set up the network identifier of user place home domain or visit territory correspondence, described professional control subsystem and service application layer are located by the network identifier corresponding home domain of institute or the connection session of visiting the territory and the memory function entity obtains user's network positioning information.
According to the invention described above technical scheme, in the network-wide basis of next generation network, distribute unitedly under the situation of network identifier, by in the network positioning information request, setting up the identifier in territory, user place, make connection session location and memory function entity can analyze the home domain or the visit territory at user place thus, and make things convenient for, obtain efficiently user's network positioning information by the connection session location and the memory function entity in territory, place.
