  • Patent number: 8914486
    Abstract: The present invention discloses a method, system and device for implementing identity identifier and location separation, to solve the technical problem that the change of the host IP address results in the connection interrupt of the terminal in the process of moving. By separating and mapping the identity identifier and location identifier, the present invention eliminates the network limitation because of the IP addresses with dual functions of the identity identifier and location identifier; the terminal host identity identifier and the terminal location identifier are mapped, the IP address is used for route only, and the host identity is denoted by the host identifier. Consequently, when the host address is changed because of moving or multi-homing and so on, the route is changed, the host identifier still keeps unchanged, and the network application and connection are not interrupted.

  • Patent number: 8738038
    Abstract: A method and system for implementing information interaction in a Next Generation Network are disclosed. The method comprises that: a Service Control Function (SCF) sends a location query request message to a ID/Locator Mapping Functional Entity (ILM-FE); the ILM-FE feeds back to the SCF a location query response message, which includes location information and/or information about a characteristic of an IP connection session accessing the service control function. The service control layer utilizes ID/locator separation technology to control the service layer, and uses the characteristic that the user identifier does not change along with the mobile location to provide a rapid transmission location management for a terminal in a moving process. Thus, the service control based on a user identifier is implemented in the NGN, and the continuity of user service is assured when the IP address of the user changes due to the mobility or the multihoming.

  • Patent number: 8705471
    Abstract: A method and a system for implementing an ID-Locator (ID/LOC) mapping are disclosed. The method includes: after allocating a new IP address to User Equipment (UE), the network side sending an ID/LOC mapping request to an ID-LOC-split Mapping Functional Entity (ILM-FE); and the ILM-FE returning a response with mapping information to the network side according to the received ID/LOC mapping request. The method initiates the ID/LOC mapping based on a network in an ID/locator separation in NGN (IPSPLIT) network, which improves the efficiency of the ID/LOC mapping.

  • Publication number: 20120124649
    Abstract: This disclosure provides an attachment method and system for ID-Loc-Split in an NGN, to implement an attachment process for an IPSPLIT-based ID-Loc-Split in an NGN, which can be combined well with various existing functional entities in the NGN, wherein a user identification is represented by a Host ID, and during the attachment process, a user is located through the Host ID, and during an authentication process, a key authentication method is provided to the Host ID; when location of the user changes due to its mobility or multihoming, the Host ID does not change; the application and connection of the transport layer is bound to the user identification, such that the application and connection will not be interrupted, and an ongoing communication session and service will not be interrupted, which guarantees the security of attachment and seamless handover when the location of a host changes due to its mobility or multihoming.
