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.

Embodiment Construction

[0013] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 , which is a flow chart of an embodiment of the method for inter-network handover of the present invention, including the following steps:

[0015] Step 101: Acquiring data cached on the data cache entity on the source network side and not yet sent to the terminal during inter-network handover;

[0016] Step 102: Process the acquired data;

[0017] Step 103: After the inter-network handover is completed, the processed data is sent on the new network side.

[0018] It can be seen from the above embodiments of the present invention that during the process of handover between two different networks, it is ensured that the data cached on the data cache entity on the source network side and not yet sent to the terminal before the execution of the handover between different networks is After the inter-network switching is completed, it...

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...
