Embodiment Construction

[0034] Embodiments of the present invention provide a context recovery method, network element, and system after the user equipment is implicitly separated. This method does not need to re-establish the user context, so the IP address used by the user equipment will not change. The services used can continue to be used, thereby improving user experience.

[0035]This context recovery method is applicable to the context recovery performed after the user equipment is implicitly separated. The mobility management network element of the second network receives the message sent by the user equipment, and when it knows that the user equipment is implicitly separated according to the message, according to the acquired Obtaining the address of the mobility management network element of the first network in the at least one network based on the identification information of the user equipment in at least one network except the second network; and the mobility from the first network acco...

Abstract

The invention discloses a user implicit separated context recovery method, net element and system. The method in the invention comprises: mobile management net element of second network receives an information from user equipment, when learning that the user equipment is implicit separated according to the informatioin, obtaining the mobile management net element address of first network in at least one network according to the obtained identification information of at least one network except the second network of the user equipment; obtaining the context information of the user equipment from the mobile management net elements in the first network according to the obtained mobile management net element address of the first network; and recovering the context of the user equipment according to the obtained context information. The invention need not re-establish the context of user equipment, so the IP address used by the user equipment does not change, and the service used by the user before can also be used, thereby the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a context recovery method, network element and system after the user is implicitly separated. Background technique [0002] 3GPP has launched a brand new evolved network, referring to figure 1 , which is a schematic diagram of the evolved network architecture in the prior art, the network includes: Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN, Evolved UMTS Terrestrial Radio Access Network) 101, used to implement all wireless related to the evolved network Function; Mobility Management Entity (MME, Mobility Management Entity) 106 is responsible for the mobility management of the control plane, including user bearer context and mobility state management, assigning user temporary identities, etc.; serving gateway entity (S-GW, Serving Gateway ) 102 is the user plane anchor point between 3GPP access networks, and term...
