Embodiment Construction

[0048] In the IPSPLIT network, for a UE, its IP address is not uniquely assigned. This IP address can belong to different operators or address domains. When the UE does not need to continue to be attached to the IPSPLIT network (for example, when the UE is turned off), the UE can take the initiative Initiate the detach process. The UE can adopt an explicit detachment method, that is, the UE explicitly requests detachment, and exchanges relevant information about the detachment process with the network side through signaling.

[0049] The system that realizes the terminal detachment process includes the terminal, the network attachment control function, and the identification and location separation mapping control function.

[0050] The terminal is used to initiate a detach request to the network attachment control function. The detach request carries the identity of the terminal.

[0051] The network attachment control function is configured to send a request for deleting the mapp...

Abstract

The invention discloses a method and a system for realizing a terminal detachment process. The method comprises that: a terminal initiates a detachment request to a network attachment control function; after receiving the detachment request, the network attachment control function transmits an identity-location-mapping relation deletion request to an identity-location-split mapping control function; and after receiving the identity-location-mapping relation deletion request, the identity-location-split mapping control function deletes saved identity-location-mapping relations of the terminal. In the method and the system, the detachment of the terminal is initiated actively by the terminal, and is securely realized when the terminal is not required to be continuously attached to an IPSPLIT network.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and system for implementing a terminal detachment process. Background technique [0002] In the current Internet layer structure, in addition to the physical layer, each layer protocol entity has its own name space, which is 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 name spaces, 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. The domain name and the IP address are resolved through a domain name server (DNS for short). In this name space structure, the IP address has a dual function, not only as the location identifier of the communication termina...
