Abstract

Embodiments of the invention disclose a network switching control method and a system thereof. The method comprises the following steps that a P-GW reports wireless congestion information of a base station to PCRF equipment; the PCRF equipment acquires a network access and switching strategy corresponding to a congestion severity according to the congestion severity corresponding to the received wireless congestion information of the base station, wherein the strategy includes a user signing level, a position and time information about whether to allow accessing an assigned network and a user signing level, a service type, a position and time information needing to be switched from the assigned network to the other network; according to the network access and switching strategy, if a user flow needs to be switched to the other network from the assigned network, an offline notification message of cutting off assigned network connection of the user is sent to the P-GW; the P-GW sends a bearing deletion request to a S-GW; the S-GW forwards the bearing deletion request to a MME; and the MME makes the user terminal of the user initiate a network switching process. By using the method and the system, intelligent switching of flow domains and optimization distribution of network resources can be realized.

Description

technical field [0001] The invention relates to communication technology, in particular to a network switching control method and system. Background technique [0002] In the mid-term of Long-Term Evolution (LTE) deployment, 3G network coverage is still widespread, but a large number of new customers choose to use LTE network access, causing LTE network congestion to increase, and some 3G network resources will be idle and wasted. This requires the user to switch between accessing the LTE network and the 3G network. [0003] Current technologies can only support handover at the base station level, switching users of congested base stations to non-congested base stations, and access domain selection without considering real-time dynamic information. For example, an existing technology commonly used at present is to deploy an access network discovery and selection function entity (ANDSF) to provide policies for user access. When a user surfs the Internet, he first connects t...
