Methods, systems, and computer readable media for communicating radio access network congestion status information for large numbers of users
First Claim
1. A method for communicating radio access network (RAN) congestion status information for a large number of users, the method comprising:
- at a policy and charging rules function (PCRF) including one or more processors;
receiving a user-specific message from a radio access network (RAN) congestion awareness function (RCAF), wherein the user-specific message is user-specific by virtue of being formatted according to a protocol for specifying a specific user equipment identifier in a message field designated by the protocol for only one user equipment identifier, wherein receiving the user-specific message comprises receiving RAN user plane congestion information (RUCI) in a non-aggregated-RUCI-report-request (NRR) command on an Np interface;
determining, as a result of a predetermined value being in the message field designated by the protocol for only one user equipment identifier, that the user-specific message indicates that one or more evolved nodeBs (eNodeBs) monitored by the RCAF are congested for a plurality of users using the one or more eNodeBs for radio access to a telecommunications network, wherein determining that the user-specific message indicates that one or more eNodeBs monitored by the RCAF are congested for a plurality of users comprises determining that a Subscription-Id attribute value pair (AVP) of the NRR command contains the predetermined value; and
in response to determining that the user-specific message indicates that the one or more eNodeBs are congested, performing one or more actions to mitigate the congestion.

Abstract
Methods, systems, and computer readable media for communicating RAN congestion status information for large numbers of users are disclosed. In one example, a method for communicating RAN congestion status information for a large number of users includes steps performed PCRF including one or more processors. The method further includes receiving a user-specific message from an RCAF. The method further includes determining that the user-specific message indicates that one or more eNodeBs monitored by the RCAF is congested for a plurality of users using the one or more eNodeBs for radio access to a telecommunications network. The method further includes, in response to determining that the user-specific message indicates that the one or more eNodeBs are congested, performing one or more actions to mitigate the congestion.

9. A system for communicating radio access network (RAN) congestion status information for large numbers of users, the system comprising:
-
one or more processors; and a policy and charging rules function (PCRF) implemented on the one or more processors; and wherein the PCRF is configured to cause the one or more processors to perform operations comprising; receiving, at the PCRF, a user-specific message from a radio access network (RAN) congestion awareness function (RCAF), wherein the user-specific message is user-specific by virtue of being formatted according to a protocol for specifying a specific user equipment identifier in a message field designated by the protocol for only one user equipment identifier, wherein receiving the user-specific message comprises receiving RAN user plane congestion information (RUCI) in a non-aggregated-RUCI-report-request (NRR) command on an Np interface; determining, at the PCRF and as a result of a predetermined value being in the message field designated by the protocol for only one user equipment identifier, that the user-specific message indicates that one or more evolved nodeBs (eNodeBs) monitored by the RCAF are congested for a plurality of users using the one or more eNodeBs for radio access to a telecommunications network, wherein determining that the user-specific message indicates that one or more eNodeBs monitored by the RCAF are congested for a plurality of users comprises determining that a Subscription-Id attribute value pair (AVP) of the NRR command contains the predetermined value; and in response to determining that the user-specific message indicates that the one or more eNodeBs are congested, performing, at the PCRF, one or more actions to mitigate the congestion. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer readable medium having stored thereon executable instructions that when executed by one or more computers control the one or more computers to perform operations comprising:
at a policy and charging rules function (PCRF) including one or more processors; receiving a user-specific message from a radio access network (RAN) congestion awareness function (RCAF), wherein the user-specific message is user-specific by virtue of being formatted according to a protocol for specifying a specific user equipment identifier in a message field designated by the protocol for only one user equipment identifier, wherein receiving the user-specific message comprises receiving RAN user plane congestion information (RUCI) in a non-aggregated-RUCI-report-request (NRR) command on an Np interface; determining, as a result of a predetermined value being in the message field designated by the protocol for only one user equipment identifier, that the user-specific message indicates that one or more evolved nodeBs (eNodeBs) monitored by the RCAF are congested for a plurality of users using the one or more eNodeBs for radio access to a telecommunications network, wherein determining that the user-specific message indicates that one or more eNodeBs monitored by the RCAF are congested for a plurality of users comprises determining that a Subscription-Id attribute value pair (AVP) of the NRR command contains the predetermined value; and in response to determining that the user-specific message indicates that the one or more eNodeBs are congested, performing one or more actions to mitigate the congestion.
