Embodiment Construction

[0030] Embodiments of the present invention provide a network switching method, a mobile network system, and a mobile management device. In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0031] Please refer to FIG. 1, which is a signaling flowchart of the first embodiment of the network switching method of the present invention. In this embodiment, in the SAE system, the UE switches from the source-side access network (home network or visited network) to the target-side access network (home network or visited network), and the user plane anchor device of the home network targets different The visited network provides the same protocol support capability, for example, supports the PMIP protocol.

[0032] In this embodiment, the mobility management device is an MME, and in 2G and 3G networks, the mobility management device may also ...

Abstract

The invention provides a network switching method, a mobile network system and a mobile management device; wherein the network switching method comprises: the mobile management equipment on the target side acquires the related anchor point information of the currently used user plane anchor point equipment of a home network or a visit network; the mobile management equipment on the target side selects the corresponding mobile anchor point equipment on the target side according to the related anchor point information of the currently used user plane anchor point equipment of a home network or a visit network and triggers the mobile anchor point equipment to construct connection with the user plane anchor point equipment. The technical proposal provided by the invention embodiment can ensure successful and rapid construction of user plane carrier on the target side.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network switching method, a mobile network system, and a mobile management device. Background technique [0002] In order to enhance the competitiveness of future mobile networks, the 3rd Generation Partnership Project (3GPP, The 3rdGeneration Partnership Project) is studying a future network architecture, which includes System Architecture Evolution (SAE, System Architecture Evolution) and evolved general Terrestrial Radio Access Network (E-UTRAN, Evolved UMTS Terrestrial Radio Access Network). The network includes three logical functional entities: a mobility management entity (MME, Mobility Management Entity), a serving gateway (S-GW, Serving Gateway) and a packet data network gateway (P-GW, Packet Data Network Gateway). MME is responsible for the mobility management of the control plane, including user context and mobility state management, allocation of user ...
