Embodiment approach 1

[0064] In the NGN (Next Generation Networks, Next Generation Networks) network based on the separation of identity and location, the NGN service control function SCF (Service Control Functions) separates the identity and location from the mapping function entity ILM-FE (Id-loc-control functional entity) to obtain transmission location management information implementation method such as Figure 5 shown.

[0065] Step 1: Authentication and authentication process.

[0066] User Equipment UE (User Equipment) requests network attachment from Access Management Functional Entity AM-FE (Access Management Functional Entity), and AM-FE completes user authentication and authentication process through ILM-FE.

[0067] Step 2: IP address configuration process.

[0068] The configuration process of the IP address is consistent with the IP address configuration process of the terminal in the general NGN system, which can be obtained through self-configuration or through DHCP. The IP addr...

Embodiment approach 2

[0075] The SCF obtains the characteristics of the IP connection session required for service control from the ILM-FE. For example, the implementation method of the information query for the SCF to obtain user information from the ILM-FE is as follows: Figure 6 shown.

[0076] Step 1: Authentication and authentication process.

[0077] The UE requests the AM-FE for network attachment, and the AM-FE completes the user authentication and authentication process through the ILM-FE.

[0078] Step 2: IP address configuration process.

[0079] The configuration process of the IP address is consistent with the IP address configuration process of the terminal in the general NGN system, which can be obtained through self-configuration or through DHCP. The IP address configuration process is: UE sends an address request to NAC-FE through DHCP, NAC-FE pushes (push) a binding information to TLM-FE, this binding information contains the temporary address allocated by NACF and other relate...

Abstract

The invention discloses a method and system for realizing information exchange in a next generation of network. In the system comprising a service control function (SCF) and an Id-loc-mapping functional entity (ILM-FE), the SCF is used for sending a location query request to the ILM-FE, and the ILM-FE is used for feeding back a location query response message to the SCF, wherein the location query response message carries location information and / or information used for accessing the IP (Internet Protocol) session characteristic of the SCF. In the invention, transmission location management is carried out on the basis of signaling exchange between the SCF and the ILM-FE, so that a service control layer can better control the service layer by utilizing the identity and location separation technology. The invention provides quick transmission location management to a terminal in a moving process by utilizing the characteristic that a user identification does not change with a moving location so as to guarantee that the service is not interrupted when the IP address of the user is changed due to mobility or multi-cavity.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for realizing information interaction in a next-generation network based on the separation of identity and location. Background technique [0002] In the current Internet layer structure, except for the physical layer, each layer protocol entity has its own name space, which are the MAC address of the link layer, the IP address of the network layer, the IP address and port number of the transport layer, and the application layer. domain name. In these namespaces, the MAC address is only required to be unique within the subnet, and the port number is only required to be unique within the host. Therefore, there are two important global namespaces in the Internet—IP address and domain name. Domain name and IP address are resolved through DNS. In such a name space structure, the IP address has dual functions, it is not only used as the position id...
