Addressing method, network element equipment and network system

Abstract

The invention discloses an addressing method which comprises the steps of: receiving an accessing request messages carrying temporary marks and transmitted by an accessing network management network element by a first movable management network element when user equipment (UE) is switched in different systems; determining the address of the management entity registered before the UE is switched and obtaining that the registered management entity before the UE switch is a second movable management network element according to the temporary marks; obtaining the shared ID of the second movable management network element; and transmitting the shared ID to the accessing network management unit, wherein the shared ID is used for helping the accessing network management network element to address the second movable management network element. By applying the technical proposal of the embodiment of the invention, the management entity accessed before the user switch and the management entity accessed after user switch are ensured to be at the same movable management network element, thus reducing the signaling interaction between different system management entities.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an addressing method, network element equipment and a network system. Background technique [0002] The core network of the wireless evolved network mainly includes three logical functional entities: the Mobility Management Entity (MME), the Serving Gateway (S-GW), and the Data Gateway (PDN Gateway, P-GW). Among them, the MME is The mobile management entity is responsible for non-access layer NAS signaling encryption, roaming, tracking and other functions, assigning user temporary identities, security functions, etc., which corresponds to the internal GPRS service support of the current Universal Mobile Telecommunications System (UMTS) The control plane part of the node (Serving GPRS Support Node, SGSN). The S-GW is responsible for the local mobility anchor point and the mobility anchor point within the 3GPP system and information related to lawful interception; the P-GW i...

Problems solved by technology

[0006] In the prior art, when the UE is handed over between networks, it cannot be guaranteed that the management entity accessed after the handover is on the same mobility management network element as the management entity accessed before the handover, so the management entity accessed after the handover cannot be reduced. Signaling interaction between the entity and the management entity accessed before the handover
