PCC strategy scheduling method and system

Abstract

The embodiment of the invention provides a PCC strategy scheduling method and system. On the basis of policy matching, all elements in all matched PCC policies are recombined for a user to form a newPCC policy, and the new PCC policy is issued to a PCEF for execution, so that the problem that only one PCC policy can be activated when multiple PCC policies are signed at the same time and conflictsoccur is solved, and flexible control of services is realized. The PCC strategy scheduling method provided by the embodiment of the invention is not limited to one strategy or rule any more, but comprehensively considers a plurality of elements in a plurality of PCC strategies, does not need to judge strategy conflicts, reduces the complexity of PCC strategy scheduling, improves the efficiency and accuracy of strategy scheduling, and has relatively high flexibility.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communication core networks, and more specifically, relate to a PCC policy scheduling method and system. Background technique [0002] The policy scheduling of policy and charging control (Policy and Charging Control, PCC) running in the existing network mainly relies on the way of rule priority and mutual exclusion group. [0003] 1. Mutual exclusion group [0004] Establish a mutually exclusive group. When adding a policy, manually predict whether there is a conflict scenario between the new policy and the old policy. The conflict scenario includes time, location, Quality of Service (QoS) action, etc. If there is, the conflict will be Both the new strategy and the old strategy are added to the mutually exclusive group and assigned priority, and the priority is only valid in the mutually exclusive group. [0005] By adding a mutually exclusive group, the efficiency of polic...

Problems solved by technology

[0005] By adding a mutually exclusive group, the efficiency of policy design is improved to a certain extent, but this solution has the following disadvantages: 1. The mutually exclusive group only takes effect for the policies signed later. If the user has signed two or more mutually exclusive groups before setting the mutually exclusive group If the policy within the exclusive group is excluded, the mutually exclusive group will not take effect; 2. Whether to join the mutually exclusive group needs to be pre-judged by the policy designer, and neither efficiency nor accuracy can be guaranteed; 3. Only policies with high priority will take effect, and policies with low priority will take effect The policy has not taken effect, and the policy scheduling is still not flexible enough

The method does not need manual comparison, can automatically detect and judge the conflict relationship between PCC strategies, saves manpower, and the detection result is accurate, but this method does not involve the scheduling method of the rules in the strategy after the conflict is detected, After using the conflict detection method to detect conflicts, manual analysis and redefinition of priorities are still required
