Problems solved by technology

Ideally, messages received and sent by PCRF are carried out step by step. However, in an actual environment, messages sent and received by RCAF1, RCAF2, and PCRF may be out of sequence due to delay, and message competition may occur. The situation (Race Condition) occurs

Embodiment 1

[0063] Figure 5 It is an interactive schematic diagram of the congestion information management method provided by Embodiment 1 of the present invention. Figure 5 In the shown method, UE1 is initially in a congested area managed by RCAF1, and the context saved by PCRF also indicates that UE1 is in the congested area managed by RCAF1, and then UE1 moves to a congested area managed by RCAF2.

[0064] Step 501. RCAF1 obtains congestion-related OAM information and congested area from RAN OAM. For UTRAN access, RCAF1 also obtains user IDs under the congested area. For E-UTRAN access, RACF1 obtains the user ID in the congested area and the corresponding activated APN (ie, PDN ID) from the MME. For UTRAN access, RCAF1 obtains the APN (ie, PDN identifier) ​​corresponding to the user identifier in the congested area from the SGSN. Assume that UE1 (user ID 1) is located in a congested area, and the activated APN is (PDN ID 1). Here, the congestion area where UE1 is located has chan...

Embodiment 2

[0077] Image 6 It is an interactive schematic diagram of the congestion information management method provided by Embodiment 2 of the present invention. Image 6 In the method shown, UE1 is initially in a congested area managed by RCAF1, and the context saved by PCRF also indicates that UE1 is in the congested area managed by RCAF1, and then UE1 moves to a congested area managed by RCAF2, and then UE1 moves again Back to the congested area managed by RCAF1.

[0078] Step 601. RCAF1 obtains congestion-related OAM information and congested area from RAN OAM. For UTRAN access, RCAF1 also obtains user IDs under the congested area. For E-UTRAN access, RACF1 obtains the user ID in the congested area and the corresponding activated APN (ie, PDN ID) from the MME. For UTRAN access, RCAF1 obtains the APN (ie, PDN identifier) ​​corresponding to the user identifier in the congested area from the SGSN. Assume that UE1 (user ID 1) is located in a congested area, and the activated APN is...

Embodiment 3

[0099] Figure 7 It is a schematic diagram of interaction of the congestion information management method provided by Embodiment 3 of the present invention. Figure 7 In the shown method, UE1 is initially in a congested area managed by RCAF1, and the context saved by PCRF also indicates that UE1 is in the congested area managed by RCAF1, and then UE1 moves to a congested area managed by RCAF2.

[0100] Step 701. RCAF1 obtains congestion-related OAM information and congested area from RAN OAM. For UTRAN access, RCAF1 also obtains user IDs under the congested area. For E-UTRAN access, RACF1 obtains the user ID in the congested area and the corresponding activated APN (ie, PDN ID) from the MME. For UTRAN access, RCAF1 obtains the APN (ie, PDN identifier) ​​corresponding to the user identifier in the congested area from the SGSN. Assume that UE1 (user ID 1) is located in a congested area, and the activated APN is (PDN ID 1). Here UE1 is located in the congestion area from conge...

Abstract

The invention provides a management method and device of congestion information. The method comprises the steps that a Policy and Charging Rules Function (PCRF) receives an RAN User Plane Congestion Information (RUCI) report sent by an RAN Congestion Awareness Function (RCAF), wherein, the RUCI report comprises a user identification and a Packet Data Network (PDN) identification; if the PCRF does not receive the response message of a Modify UEcontext Request (MUR) message sent by the RCAF, the PCRF rejects the RUCI report, wherein, the MUR message comprises request information of asking to delete the user identification and the Packet Data Network (PDN) identification stored by the RCAF.

Description

technical field [0001] The present invention relates to the communication field, in particular to a congestion information management method and device. Background technique [0002] figure 1 It is a schematic diagram of a policy and charging control architecture (Policy and Charging Control, referred to as PCC) defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) in the prior art, such as figure 1 As shown, the Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) is the core of the entire PCC architecture. To formulate the control strategy, the PCRF needs to combine the service information received from the Application Function (AF for short), the subscription information received from the Subscription Profile Repository (SPR for short), the strategy configured by the operator, and the like. The PCRF will issue the control policy formulated for the service to the Policy and Charging ...
