Method for mobility management, measuring method, system and equipment

Abstract

The invention discloses a method for mobility management, comprising the following steps: a universal access network controller receives indication information sent by a mobile station; and the universal access network controller selects a mode of the universal access network according to the indication information. The invention also discloses a system and equipment of mobility management. In the embodiment of the invention, when registration between GERAN/UTRAN and GAN is initiated, a user terminal can preferably select different GAN modes according to the own network to carry out registration or select an expected GAN mode to carry out registration, thus being capable of optimizing the network resource.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a mobility management method, measurement method, system and equipment. Background technique [0002] In the mobile communication network, the communication capability of the access network, which serves as a bridge between the end user and the core switching network, directly affects the user's experience of mobile services. With the advantages of high access bandwidth and low communication cost, short-distance wireless communication technology has attracted more and more attention. The way of providing wireless access based on short-distance wireless communication technology in the license-free frequency band is rapidly popularizing, and it coexists with traditional wireless access networks in the local area or even in the metropolitan area. Therefore, traditional radio access networks, such as: UTRAN (UMTS Terrestrial Radio Access Network, Terrestrial Rad...

AI Technical Summary

Problems solved by technology

When a handover or reselection occurs between the GAN network and the GERAN / UTRAN network, how does the GAN network or the terminal obtain these priority information and apply the priority information, and the prior art does not provide a corresponding solution;

[0013] 4. At present, the network side of the terminal supporting multiple access networks can control the measurement and measurement reporting. For example, when the mobile phone is in the GERAN CS dedicated state, the network can issue commands or instruct the terminal to prohibit the measurement of E-UTRAN cells and The UTRAN cell is used to avoid excessive measurement and / or measurement reporting. However, when the prior art solution controls the measurement and measurement reporting, the terminal cannot normally switch to the GAN cell.

[0014] The existing technology is not controllable to which mode the MS can preferably switch to, so it will lead to an increase in switching complexity and unnecessary overhead

At the same time, the existing technology does not take into account the impact of the introduction of the priority mechanism and the introduction of measurement control on the GAN network, so that normal cell reselection and handover between the GAN cell and the GERAN / UTRAN cell cannot be performed
