Problems solved by technology

[0005] At present, AF as an Internet application cannot know the IMSI and MSISDN of the mobile terminal user, and can only identify the user through the IP address; however, the operator network generally deploys Network Address Translation (NAT) equipment, which causes the core network to allocate the mobile terminal user. Private network IP address, and what AF sees is the public network IP address of the user after passing through NAT, so PCRF cannot complete the session binding between Rx and Gx interfaces, making PCEF unable to realize the quality of service (QoS) control of user services

Abstract

The invention discloses a session binding method and a session binding system. The method comprises steps that, user identification information of a user terminal user is acquired by an application client when a user terminal utilizes an Internet application, the information comprises IMSI or MSISDN and / or a local IP address, and an application server is reported through reporting the information; a resource applying message is sent to a capability open platform by the application server when applying QoS resource for the user is determined, the user identification information is contained, or a source IP address is further contained; the QoS resource is distributed to the user terminal user by the capability open platform, the IMSI or the MSISDN in the resource applying message and the local IP address are packaged into Subscription-Id AVP and Framed-IP-Address AVP which are sent to PCRF through an Rx interface; Rx and Gx interface session binding is realized by the PCRF, strategy control information of the user terminal user is generated and is issued to the PCEF. Through the method, QoS control on user business can be realized.

Description

technical field [0001] The present invention relates to communication technology, in particular to a session binding method and system. Background technique [0002] With the rapid development of the mobile Internet today, open cooperation has become the consensus of mainstream manufacturers around the world. The popularization and rapid promotion of mobile Internet applications represented by WeChat and Weibo have gradually broken down industry barriers, and the boundaries between Internet application companies and telecom operators have become increasingly blurred. Operators are facing an unprecedented technological revolution and impact. In the mobile Internet environment, the business model of opening up its own capabilities and forming a new business ecosystem has increasingly proved to be the next gold nugget. [0003] China Telecom has built mobile network intelligence based on 3GPP Policy and Charging Control (PCC) on Code Division Multiple Access (CDMA), Enhanced ...
