Embodiment approach 1

[0017] Referring to Fig. 1 and Fig. 3, Embodiment 1 of the present invention can be briefly described as: when the user is in the home domain of the network, the SCSA can obtain network location information from the CLF through the parameters of Assigned IP Address, Address Realm and AF Identity.

[0018] The precondition for implementing the present invention is that network identifiers are distributed uniformly within the entire network. The connection session location and storage functional entity judges that the user is in the home domain through the fact that the identifier in the network location information request is empty or the identifier is the same as the identifier of the home domain, and then directly responds the network location information to the service controller System and business application layer, specifically,

[0019] (1) SCSA sends a network location information query (Location Information Query) message to the CLF;

[0020] (2) CLF receives the Loca...

Embodiment approach 2

[0023] Referring to Fig. 2 and Fig. 4, the second embodiment of the present invention can be briefly described as: when the user is in the visited domain of the network, the CLF-Proxy forwards the network location information request to the CLF-Server indicated by the identifier, and sends the The network location information obtained by the CLF-Server responds to the SCSA in the home domain.

[0024] The precondition for implementing the present invention is that network identifiers are distributed uniformly within the entire network. The method comprises the steps of:

[0025] (1) SCSA sends a Location Information Query message to CLF;

[0026] (2) After receiving the Location Information Query message sent by the SCSA, the CLF determines the visited domain where the user is located by analyzing the identifier in the network location information request, and forwards the Location Information Query message to the CLF-Server by the CLF-Proxy;

[0027] (3) CLF-Server obtains ...

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 [0001] The present invention relates to the technical field of next generation network (NGN, Next Generation Network) mobile communication, specifically relate to in NGN architecture, service control subsystem and service application layer (SCSA, Service Control Subsystems and Applications) obtain user's network location information ( Network LocationInformation) method. Background technique [0002] At present, new technologies represented by the Internet are profoundly affecting the concept and system of traditional telecommunication networks, and the next-generation network is one of the highlights that attract the most attention. In a current NGN architecture, the main function of the Network Attachment Subsystem (NASS, Network Attachment Subsystem) shown in Figure 1 and Figure 2 is to dynamically allocate Internet Protocol (IP) addresses and other terminal configuration parameters, Authentication and authentication of users at the IP layer, network acce...
