Abstract

The invention discloses a method for processing a conversation service. According to the scheme, the conversation service can be released when an OCS does not receive first information sent by a PCRF solid and used for requesting bandwidth resource decision-making factor information within preset duration, and/or the OCS receives third information sent by the PCRF solid and used for indicating to stop the conversation service. In this way, even if conversation resources are released through the PCRF solid, in the scene that the OCS does not receive the third information all the time, the OCS can release session service resources in time, and the defects that in the conversation service processing process, memories or database resources are wasted, and wrong alarm information is sent are overcome.

Description

A kind of method, OCS and PCRF entity of processing session service
Technical field
The present invention relates to communication technical field, particularly a kind of method, OCS and PCRF entity of processing session service.
Background technology
3GPP (3rd Generation Partnership Project, 3G (Third Generation) Moblie standardization body) provide under the scene for data service bandwidth control in TS29.219 agreement, PCRF (Policy and Charging Rules Function, strategy and charging rule functions) entity and OCS (Online Charging System, Online Charging System) related periphery functional entity, and protocol interaction mode between each functional entity.
PCRF entity is as the main body of data service bandwidth decision-making, and bandwidth control decision rule is all configured on PCRF entity, for needing bandwidth on demand mandate or the instruction bandwidth scene of decision-making again, is all to calculate by PCRF entity; For the bandwidth resources decision factor information relying in bandwidth decision rule, PCRF entity is interfaced to OCS by Sy and obtains.
In the time of user's usage data business, first PCEF (Policy and Charging Enforcement Function, policy control and charging strengthen function) entity can pass through Gx interface to PCRF entity application available bandwidth; PCRF entity obtains bandwidth resources decision factor information computation bandwidth by Sy interface from OCS, and then, the bandwidth calculating is returned to PCEF entity by PCRF entity; PCEF entity reports accounting request to complete the reserved and deduction of expense to OCS by Gy interface.
Current session establishment process is as follows, as shown in Figure 1:
Step 1:PCEF entity receives after the data service request of terminal transmission, reports Initial CCR (Credit Control Request, charging control request) message by Gx interface to PCRF entity;
Step 2:PCRF entity sends Initial SLR (Spending Limit Request) message by Sy interface to OCS, for bandwidth on demand resource decision factor information;
Step 3:OCS sends Initial SLA (Spending Limit Acknowledge) message to PCRF entity, PCRF entity computation bandwidth resource, and the information of the bandwidth resources that calculate is sent to PCEF entity, complete session establishment.
In the time of end session, said process also comprises following operation:
Step 4:PCEF entity reports Termination CCR message by Gx interface to PCRF entity;
Step 5:PCRF entity discharges the Session Resources that PCRF entity retains, and sends STR (Session-Termination-Request) message by Sy interface to OCS, for asking OCS to discharge the Session Resources that OCS retains;
Step 6:OCS returns to STA (Session-Termination-Answer) message by Sy interface to PCRF entity, discharges the Session Resources that OCS retains.
The release of current OCS session, the STR message can only PCR-based F entity reporting, if PCRF entity has discharged Session Resources, but, due to network flash or other reason (as overload Flow Control), OCS never receives STR message, preserving sessions service resources always, like this, there is following defect:
1) because PCRF entity has discharged Session Resources, that is to say, session is invalid, and also store session resource of OCS now, has the problem of waste internal memory or database resource;
2) OCS thinks that session is still effective, may issue SNR (Spending-Notification-Request) message to PCRF entity, and this SNR message for the Session Resources of session discharged at PCRF entity, session is invalid, now, PCRF entity receives after SNR message, and can take for is the information such as virus, and then sends the problem of wrong warning information.
Therefore there is waste internal memory or database resource, send the problem of wrong warning information in current processing session service process.
In prior art, the release of OCS session, the 3rd message can only PCR-based F entity reporting, if PCRF entity has discharged Session Resources, but, due to network flash or other reason (as overload Flow Control), OCS never receives the words of the 3rd message, preserving sessions service resources always, and in the embodiment of the present invention, OCS in default duration, do not receive that described PCRF entity sends for the first message of bandwidth on demand resource decision factor information again, and/or, while receiving the 3rd message that is used to indicate termination session service of described PCRF entity transmission, all can releasing session business, like this, even discharged Session Resources at PCRF entity, but, OCS never receives under the scene of the 3rd message, OCS can discharge convention business resource in time, avoid processing waste internal memory or the database resource that session service process exists, send the defect of wrong warning information.
