A location-based PCC session establishment method and system

Abstract

The invention discloses a position-based PCC (policy and charging control) session setup method and system; the method comprises: receiving by a network manager terminal, a session setup command entered by the outside and carrying positional information, transmitting the session setup command to a network node that provides services for a position corresponding to the positional information; acquiring by the network node, user identifiers of all users at the corresponding position based on the positional information; determining by the network node, users, who are current users served by the network node, among the corresponding users based on the user identifiers, and selecting target users with no PCC sessions set up from the users; transmitting by the network node, session setup information to a PGW (packet gateway) that serves the target users, and directing the PGW to set up PCC sessions for the target users. It can be seen that the method and system according to the technical scheme disclosed by the application can set up PCC sessions for users served by network nodes but having no PCC sessions set up when accessing a network.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a location-based PCC session establishment method and system. Background technique [0002] According to the 3GPP (3rd Generation Partnership Project, the third generation partnership project, the standard organization is responsible for formulating mobile communication standards) standards, LTE (Long Term Evolution, long-term evolution, this term means 4G wireless access) users access EPC (Evolved Packet Core, evolved packet core, this technical term refers to the 4G core network) network, in order to save system resources or other reasons, the network side may not establish a PCC (Policy Control and Charging, policy control and charging) session for the user. [0003] However, according to the 3GPP standard, if the user does not establish a PCC session when accessing the EPC network, then the user will no longer be able to establish a PCC s...

Problems solved by technology

[0003] However, according to the 3GPP standard, if the user does not establish a PCC session when accessing the EPC network, then the user will no longer be able to establish a PCC session during the user access process, unless the user goes offline and then re-connects to the network without a PCC session , which means that the network side cannot dynamically adjust the user's QoS, let alone obtain the user's location information in time
