Consumption quota monitoring method and device

Abstract

The invention discloses a consumption quota monitoring method and device. The method comprises the following steps: a PCRF querying a non-subscribed user consumption quota state to an OCS through a SLR message, wherein the SLR message carries a query operation instruction and the user consumption quota information needed to be queried; the PCRF receiving a consumption quota response SLA message sent by the OCS and acquiring the corresponding user consumption quota state; the PCRF cancelling the subscription of the predetermined type of user consumption quota state to the OCS through the SLR message since the SPR modifies the configuration, or the PCRF finds that certain types of user consumption quota states of the subscriber needs to be cancelled in the strategy decision process which is performed by the PCRF when the PCEF requests the consumption related quota, wherein the SLR message carries an operation instruction of cancelling the subscription and the user consumption quota information needed to be unsubscribed; the PCRF receiving the subscription cancellation successful response sent by the OCS through the SLA message.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a consumption quota monitoring method and device. Background technique [0002] With the continuous evolution of Policy and Charging Control (PCC) architecture, such as figure 1 As shown, the PCC architecture includes the following functional entities: Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), Policy and Charging Enforcement Function (Policy and Control Enforcement Function, PCEF), bearer binding and event reporting Function (BearerBinding and Event Reporting Function, BBERF), application function (ApplicationFunction, AF), traffic monitoring function entity (Traffic Detection Function, TDF), user subscription database (Subscription Profile Repository, SPR), offline charging system (Offlinecharging system, OFCS), Online charging system (Online charging system, OCS). [0003] The PCRF is mainly responsible for the formulation of policies a...

Problems solved by technology

In addition, to cancel certain consumption quota subscriptions of users at present, the operation of releasing the session must be triggered through the session termination request (Session-Termination-Request, STR) to cancel the consumption quota subscription, and there is no method to directly cancel the subscription without releasing the session

[0008] As mentioned above, the current subscription method has the following defects: 1. It lacks a query method to directly query the user's consumption quota and does not require OCS to push the consumption quota status. Load level; 2. There is no method to directly cancel the subscription consumption quota status without releasing the session. At present, when the system does not need to subscribe to the consumption quota status temporarily, it can only cancel the subscription by releasing the session. When it is necessary to subscribe to other consumption quota status of the user in the future , re-establish the session and re-subscribe to the consumption quota state

The process of releasing sessions and re-establishing sessions reduces the processing capacity of the PCRF / OCS system and also increases the load level between systems
