Problems solved by technology

For UEs that do not need to maintain service continuity, if the network still selects the previously used PGW for them, when the UE moves far away from the original PGW, the service flow between it and the PDN network will take a long time. The transmission path, which will cause a lot of waste of routing resources
[0004] In order to solve the problem of wasting routing resources in the prior art 1, a new network mechanism, Selected IP Traffic Offload (SIPTO for short), is introduced in the 3GPP network

Abstract

Disclosed in the embodiment of the present invention is a method and device for processing service continuity; an MME, by means of acquiring the service continuity information of a PDN connection of a UE, and on the basis of said service continuity information of the PDN connection, determines whether the PDN connection needs to maintain service continuity; if the PDN connection does not need to maintain service continuity, then the MME selects a new packet data gateway PGW for the UE, and if the PDN connection needs to maintain service continuity, then the MME maintains the original PGW connection. The present invention can ensure the normal service connection of a UE needing to maintain service continuity, and on the premise of not influencing the service connectivity of the service of a PDN connection, can select a more suitable PGW for a UE not needing to maintain service continuity, optimising the UE path and saving routing resources.

Description

technical field [0001] The present invention relates to communication technology, in particular to a business continuity judgment method and equipment. Background technique [0002] Service continuity in a network refers to the feature of ensuring that ongoing network services will not be interrupted, especially in a mobile network, ensuring service continuity is an important feature of the network. The continuity of the network service can be realized in various ways, for example, it can be guaranteed by the relevant mechanism of the application layer, and can also be guaranteed by the mechanism of the network layer such as the Internet Protocol (Internet Protocol, IP) layer. The continuity of some services is realized by ensuring that the IP address of the user equipment (User Equipment, UE for short) remains unchanged during the entire service session. In order to ensure that the IP address of the UE does not change, it is required that the IP address anchor used by the ...
