Customer premise equipment switching method and system in radio network

Abstract

The invention relates to the wireless communication field, which discloses a user device switching method of wireless communication and a system thereof and causes relatively good balance of business experience of the users and route optimization of network. When switching, the invention determines whether to move a business anchor point or not according to requirement of business continuity. The business anchor point of the business needing to guarantee continuity is kept the same, which can promote the business experience of the users. The business anchor point of the business that does not need to guarantee continuity is moved to a target lateral network, which can cause the route to be optimized and achieve purposes of saving network transmission resource and shortening transmission delay of business data. Attributive business can be determined as the business that needs to guarantee continuity and local business can be judged whether the business needs to guarantee continuity or not according to factors of business types, QoS requirement of the business, subscriber profile, operation strategies of operators, processing ability of network equipment, etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the handover technology of user equipment. Background technique [0002] With the gradual development of communications, people's requirements for mobile communications are getting higher and higher, and the existing network architecture and protocols of the 3rd Generation Partnership Project (3GPP for short) can no longer meet users' requirements for mobile communications. Therefore, 3GPP proposed a concept of an evolved network that serves future communication requirements. [0003] In order to ensure the competitiveness of the 3GPP system in the next 10 years or even longer, especially to strengthen the ability of the 3GPP system to handle the rapidly growing IP data services, 3GPP started the Long Term Evolution (LTE) from the second half of 2004 The "LTE") project and the System Architecture Evolution ("SAE" for short) project, LTE and SAE are collectively referred to ...

Problems solved by technology

How to deploy the four logical functional entities: MME, UPE, 3GPP anchor point and PDN gateway on specific physical equipment, 3GPP organization has not yet clarified

[0015] However, in the prior art, there is no solution for how to ensure service continuity and improve routing optimization when UE is switched across local domains in active state in SAE / LTE network
