Abstract

The invention discloses a method for realizing switching between networks, which comprises the following steps: a control network element of a target network allocates wireless resource for a mobile station MS in the target network according to a switching request from a control network element of a source network, and then notifies the MS with the allocated wireless resource; the MS determines to send out uplink data on the target network according to the wireless resource notified by the control network element of the target network; after the control network element of the target network determines to successfully notify the MS with the allocated wireless resource, the message that the switching is finished is sent to the network element of the source network. In addition, the invention also discloses a system and a device for realizing switching between the networks. The method, the system and the device provided by the invention can avoid switching failure caused by rapid worsening of wireless environment of a source cell and improve the service quality since the MS need not wait for receiving a switching command sent by the control network element of the source network inside the source network.

Description

technical field

[0001] The present invention relates to mobile communication technology, in particular to a method, system and device for switching between networks. Background technique

[0002] In the mobile communication network, the access network acts as a bridge between the terminal user and the core switching network, and its communication capability directly affects the user's experience of mobile services.

[0003] With the continuous development of short-distance wireless communication and other technologies, user terminals can simultaneously send and receive data in two types of access networks. If the user terminal is in the traditional wireless access network and the license-free mobile access network, or the user terminal is in the traditional wireless access network and the World Interoperability for Microwave Access (Wimax, World Interoperability for Microwave Access) system, it can send and receive two data in the network. Therefore, the seamless switching...
