Abstract
Disclosed are a method and an apparatus for managing congestion information. The method includes: a policy and charging rules function (PCRF) receiving an RAN user plane congestion information, RUCI, report sent by an RAN congestion awareness function (RCAF) herein, the RUCI report includes a user identifier and a Packet Data Network, PDN, identifier; if not receiving an answer message for a modify UEcontext request(MUR) message sent to the RCAF, the PCRF rejecting the RUCI report, herein, the MUR message includes request information for deleting the context of the user identifier and the PDN identifier stored in the RCAF.
Claims21
A method for managing congestion information, comprising:
- receiving, by a policy and charging rules function, PCRF, an radio access network, RAN, user plane congestion information, RUCI, report sent by an RAN congestion awareness function, RCAF, wherein, the RUCI report comprises a user identifier and a Packet Data Network, PDN, identifier;
- and
- if the PCRF does not receive an answer message for a modify UEcontext request, MUR, message sent to the RCAF, rejecting, by the PCRF, the RUCI report, wherein, the MUR message comprises request information for deleting context of the user identifier and the PDN identifier stored in the RCAF.
A method for managing congestion information, comprising:
- receiving, by a radio access network, RAN, congestion awareness function, RCAF, a modify UEcontext request, MUR, message sent by a policy and charging rules function, PCRF, wherein, the MUR message comprises request information for deleting context of a user identifier and a PDN identifier stored in the RCAF;
- and
- managing, by the RCAF, the context of the user identifier and the PDN identifier according to the MUR message.
The method according to claim 44, wherein, managing, by the RCAF, the context of the user identifier and the PDN identifier according to the MUR message comprises:
- the RCAF deleting the context of the user identifier and the PDN identifier according to the MUR.
An apparatus for managing congestion information, comprising:
- a first receiving module, configured to receive an radio access network, RAN, user plane congestion information, RUCI, report sent by an RAN congestion awareness function, RCAF, wherein, the RUCI report comprises a user identifier and a Packet Data Network, PDN, identifier;
- and
- a first managing module, configured to reject the RUCI report if determining that an answer message for a modify UEcontext request, MUR, message sent to the RCAF is not received, wherein, the MUR message comprises request information for deleting context of the user identifier and the PDN identifier stored in the RCAF.
An apparatus for managing congestion information, comprising:
- a second receiving module, configured to receive a modify UEcontext request, MUR, message sent by a policy and charging rules function, PCRF, wherein, the MUR message comprises request information for deleting context of a user identifier and a PDN identifier stored in an RCAF, and
- a second managing module, configured to manage the context of the user identifier and the PDN identifier according to the MUR message.
The apparatus according to claim 4414, wherein, the second managing module is configured to:
- delete the context of the user identifier and the PDN identifier according to a MUR.
