Description
Technical field
The present invention relates to the communications field, in particular to a kind of policy control method and system.
Background technique
During the opening of intelligent pipeline ability, needs to solve or avoids following problems:
Problem 1: ability open platform is carrying out energy such as mobile network QoS (Quality of Service, service quality)
When the backward operation of power, since platform can not obtain the user account information of the mobile networks such as Subscriber Number survey, thus can not base
Disbursement and sattlement is carried out in number of users and third party.
Problem 2: third party when handling capacity open platform carries out mobile network QoS ability calling needs that letter will be called
PCRF (Policy and Charging Rules Function, strategy and the charging regulation function that breath is routed to as user service
Can) unit, and realize Gx/Rx binding session.
Problem 3: after user is located at NAT (Network Address Translation, network address translation) equipment
(such as mobile phone is accessed by 4G MIFI), the private network IP address of user terminal local are not the private network IP of core net distribution, therefore nothing
Method is based on this and realizes Gx/Rx binding session.
Problem 4: MDN (Mobile Directory Number, Mobile Directory Number), the IMSI of user
(International Mobile Subscriber Identification Number, international mobile subscriber identity) etc.
Network side information belongs to privacy of user, should not be directly passed to third-party application.
Problem 5: under the scene that user accesses there are more APN (Access Point Name, access point name), only
User private network IP address may be unable to complete Gx/Rx binding session.
In currently existing scheme, problem above can not be solved or avoided simultaneously.
Summary of the invention
