Application server billing
View Patent ↗An Application Server entity in an IP Multimedia Subsystem (IMS) network comprises an interface for interfacing with an application and control logic which is arranged to inspect signalling information received from the application via the interface in the form of Extensible Markup Language (XML). The received signalling information is compared with stored rule data which specifies a relationship between an element in the signalling information and an action that should be taken and output data is generated based on the comparison. The Application Server can output operational measurements and/or charging information which more accurately reflect usage made of the Application Server resources. The need for a separate OSA/Parlay-X gateway can be avoided.
1. An Application Server for use in an IP Multimedia Subsystem (IMS) network, comprising:
a first interface arranged to enable communication between said application server and a telecommunications server of the IMS network;
a second interface arranged to enable communication between said application server and an application;
a processor comprising:
processing resources for implementing a service provided by said application and providing said service to users of the IMS network via said first interface; and
control logic arranged to:
inspect signaling information received from the application via said second interface in the form of Extensible Markup Language (XML);
compare said received signaling information with stored rule data which specifies a relationship between an element in said signaling information and an action that should be taken including when charging information should be generated; and
generate charging information on the basis of the comparison; and
an output arranged to package the charging information into an output format compatible with either a Charging Data Function (CDF) or Online Charging System (OCS) in the IMS network.
2. An Application Server according to claim 1 wherein the output is arranged to issue charging information in the form of Accounting Requests.
3. An Application Server for use in an IP Multimedia Subsystem (IMS) network, comprising:
a first interface arranged to enable communication between said application server and a telecommunications server of the IMS network;
a second interface arranged to enable communication between said application server and an application; and
a processor comprising:
processing resources for implementing a service provided by said application and providing said service to users of the IMS network via said first interface; and
control logic arranged to:
inspect signaling information received from the application via said second interface in the form of Extensible Markup Language (XML);
compare said received signaling information with stored rule data which specifies a relationship between an element in said, signaling information and an action that should be taken including when charging information should be generated;
collate charging information during the process of comparing the received signaling information with stored rule data;
generate charging information on the basis of the comparison; and
output the collated charging information.
4. An Application Server according to claim 1 wherein the control logic is arranged to access stored rule data representing at least one of: rules of the network operator; rules for a subscriber and rules for governance of the application.
5. An Application Server according to claim 1 wherein the Application Server is an Open Service Architecture Service Capability Server (OSA SCS).
6. An Application Server according to claim 1 wherein the second interface is arranged to interface with an application hosted externally of the IMS network.
7. A method of generating charging information in an IP Multimedia Subsystem (IMS) network, the method comprising:
connecting users of the IMS network to an application server via a first interface arranged to enable communication between said application server and a telecommunications server of the IMS network;
receiving signaling information via a second interface arranged to enable communication between said application server and an application, the second interface being part of said application server;
implementing a service provided by said application and providing said service to users of the IMS network via said first interface;
inspecting the received signaling information in the form of Extensible Markup Language (XML);
comparing the received signaling information with stored rule data which specifies a relationship between an element in the signaling information and an action that should be taken including when charging information should be generated;
generating charging information on the basis of the comparison; and
packaging the charging information into an output format compatible with either a Charging Data Function (CDF) or Online Charging System (OCS) in the IMS network.
8. A method according to claim 7 wherein the output format is an Accounting Request.
9. A method of generating charging information in an IP Multimedia Subsystem (IMS) network, the method comprising:
connecting users of the IMS network to an application server via a first interface arranged to enable communication between said application server and a telecommunications server of the IMS network;
receiving signaling information via a second interface arranged to enable communication between said application server and an application, the second interface being part of said application server;
implementing a service provided by said application and providing said service to users of the IMS network via said first interface;
inspecting the received signaling information in the form of Extensible Markup Language (XML);
comparing the received signaling information with stored rule data which specifies a relationship between an element in the signaling information and an action that should be taken including when charging information should be generated;
collating the charging information during the process of comparing the received signaling information with stored rule data,
generating charging information on the basis of the comparison, and
outputting the collated charging information.
10. A method according to claim 7 wherein the stored rule data represents at least one of: rules of the network operator; rules for a subscriber and rules for governance of the application.
11. A method according to claim 7 wherein the Application Server is an Open Service Architecture Service Capability Server (OSA SCS).
12. A method according to claim 7 wherein the signaling information is received from an application hosted externally of the IMS network.
13. A computer program product comprising a non-transitory machine-readable medium carrying instructions for causing a processor to implement the method of claim 7 .
