Embodiment Construction

[0037] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] In this embodiment, the machine-card separation mode is used for illustration, but it is also applicable to the future machine-card integration solution, and no matter which terminal mode is adopted, it will not affect the implementation of the present invention.

[0039] Since WiMAX terminals do not currently have a concept similar to a USIM card, the terminal adopts a dual-mode dual-standby mode, that is, some modules of WiMAX in the terminal adopt the WiMAX design mode for processing, and some other standards such as WCDMA use USIM, SIM or The mode of the UIM card is processed.

[0040] Similarly, with the development of terminals in the future, WiMAX term...

Abstract

The invention discloses a terminal switching method in a multi-network mode, comprising the following steps: setting a buffer area in a data buffering module of a terminal and setting an identifier for recording node marks in a terminal management/control module; a signaling processing module of a terminal Communicating with the network to stop data transmission between the data processing module and the server, the terminal management/control module caches the data related to data transmission in the cache area, and uses the identification to record the node flag; and the terminal registers to another network. The invention also discloses that the terminal switching device under the multi-network mode includes: a data processing module, a signaling processing module, a data cache module, and a terminal management/control module. Through the present invention, the signaling processing mode of opening a cache area and related suspend, resume, etc. is adopted to ensure no loss in data transmission, especially the management of the buffer area ensures the integrity of the data.

Description

technical field [0001] The invention relates to the interconnection and intercommunication between a WiMAX network and other networks under multi-network integration, and in particular to a method and a device for keeping data services uninterrupted or data packets lost when a WiMAX data card terminal is switched with other networks. Background technique [0002] With the deployment of communication technologies and new services. The interaction between the market and technology has gradually revealed some new features in the future communication field. Broadband mobility and mobile broadband have gradually become the trend of technological development in the two fields, and they complement each other and promote each other. In terms of broadband mobility, the IEEE 802 working group has successively formulated technical specifications such as WLAN and WiMAX, intending to gradually realize broadband mobility along the evolution route of fixed, nomadic / portable, and mobile. A...
