A network node and method for enhancing message communication between a first network node and a second network node in a communication network is provided. The first network node receives an input message from the second network node wherein the input message contains at least one parameter. The first network node then identifies in the received input message the presence of the at least one parameter, wherein the parameter is unknown to the first network node. After identifying at least one unknown parameter, the first network node sends a request message to the second network node for obtaining meta-data associated with the identified unknown parameter. The first network node then receives a response message from the second network node containing the said obtained meta-data associated with the identified unknown parameter. After receiving the response message, the first network node updates the obtained meta-data associated with the unknown parameter.

Method and network node for enhancing message communication in a communication network

A method, performed in a Policy and Charging Rules Function (PCRF), for managing subscription to policy counters maintained at an Online Charging System (OCS) is disclosed. The PCRF is operable to communicate with the OCS over an Sy reference. The method comprises receiving a Multiple Users subscription trigger from a network operator (), the Multiple Users subscription trigger identifying a reference network policy and a subject network policy. The method further comprises sending a Spending Limit Request (SLR) command to the OCS (), the SLR command specifying an identifier of a subject policy counter for the subject network policy and specifying application of the SLR command with respect to the subject policy counter to all ongoing Sy sessions between the PCRF and the OCS which already include a subscription to a policy counter for the reference network policy. Also disclosed is a method, performed in an OCS, for managing subscription by a PCRF to policy counters maintained at the OCS. The method comprises receiving an SLR command from the PCRF (), the SLR command specifying an identifier of a subject policy counter for a subject network policy and specifying application of the SLR command with respect to the subject policy counter to all ongoing Sy sessions between the PCRF and the OCS which already include a subscription to a policy counter for a reference network policy. The method also comprises applying the received SLR command with respect to the subject policy counter to each ongoing Sy session between the OCS and the PCRF which already includes a subscription to a policy counter for the reference network policy (-). Also disclosed are a PCRF, an OCS and a computer program product.

Method and apparatus for managing subscription to policy counters

A method, performed in a Policy and Charging Rules Function (PCRF) for managing subscription to a policy counter maintained at an Online Charging System (OCS) is disclosed. The PCRF is operable to communicate with the OCS over an Sy reference point. The method comprises receiving an All Users subscription trigger from a network operator (), the All Users subscription trigger identifying a network policy, and sending a Spending Limit Request (SLR) command to the OCS (), the SLR command specifying an identifier of a policy counter for the network policy and specifying application of the SLR command to all ongoing Sy sessions between the PCRF and the OCS. Also disclosed is a method, performed in an OCS, for managing subscription by a PCRF to a policy counter maintained at the OCS. The method comprises receiving an SLR command from the PCRF (), the SLR command specifying an identifier of a policy counter and specifying application of the SLR command to all ongoing Sy sessions between the PCRF and the OCS, and applying the received SLR command with respect to the specified policy counter identifier to each ongoing Sy session between the OCS and the PCRF (-). Also disclosed are a PCRF, an OCS and a computer program product.
