Method and device for realizing different network switching

Abstract

The embodiment of the invention discloses a method and a device for realizing different network switching. The method comprises the following steps: acquiring data which is registered on a source network side data register entity in a different network switching process and is not sent to a terminal; processing the acquired data; and sending the processed data to a new network side after the different network is switched. The invention ensures that the data which is registered on the source network side data register entity before different network switching and is not sent to the terminal issent to the terminal through the new network side after finishing the different network switching, thereby achieving lossless data.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for realizing switching between different networks. Background technique [0002] At present, the core network structure of a new generation of wireless mobile communication has been formed. The new generation of wireless communication core network requires access to GSM (Global System of Mobile Communications, Global System for Mobile Communications), WCDMA (Wideband Code Division Multiple Addressing, Wideband Code Division Multiple Access) and LTE (Long Term Evolution, Long Term Evolution) In addition to 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) access technology terminals, it can also access WLAN (Wireless Local Area Network, wireless local area network), WiMAX (Worldwide Interoperability for Microwave Access, global microwave interoperability access network) ) and CDMA (Code Division Multiple Addressi...

AI Technical Summary

Problems solved by technology

[0004] However, during the process of creating the present invention, the inventor found that there are at least the following problems in the prior art: because the terminal will often switch between different networks as needed, for example, the terminal on the Non-3GPP network side will switch to the 3GPP network as needed side, or the terminal on the 3GPP network side switches to the Non-3GPP network side as needed

However, when the terminal on the Non-3GPP network side switches to the 3GPP network side as needed and completes the handover, the data stored on the Non-3GPP Access GW and not delivered to the terminal is changed due to the terminal switching the network. channel, but cannot be delivered to the terminal, so the data cached in the Non-3GPP Access GW on the source network side is lost

Similarly, when the terminal on the 3GPP network side switches to the Non-3GPP network side, the data cached in the eNodeB on the 3GPP network side will also be lost.
