Database and a method for obtaining the address of a quality of service and charging control entity in an IMS network using such a database
View Patent ↗A database ( 51 ) accessible in an IMS network and including at least one record including: an identifier of a terminal ( 10 ) in a transport plane; an identifier of said terminal ( 10 ) in a signaling plane; and at least one address of a quality of service and charging control entity ( 40 ) in said network.
1. A database accessible in an IMS network, said database comprising means for storing at least one record including:
an identifier of a terminal in a transport plane;
an identifier of said terminal in a signaling plane; and
at least one address of a quality of service and charging control entity in said network which manages said terminal,
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for a session involving said terminal to a gateway of the network in response to a request including the identifier of said terminal in the transport plane sent by said gateway; and
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for said session to an application entity in response to a request including the identifier of said terminal in the signaling plane sent by said application entity.
2. The database according to claim 1 , wherein said record further includes a session identifier.
3. The database according to claim 1 , wherein said record further includes service information on a session in said network.
4. The database according to claim 1 , wherein the database is configured to obtain service information on a session in said network by interrogating a quality of service and charging control entity in said network.
5. A method of obtaining an address of a quality of service and charging control entity in an IMS network, comprising sending a request, including at least one identifier of a requesting terminal, to a database wherein said database is accessible in an IMS network and wherein said database comprises at least one record stored therein, said at least one record comprising:
an identifier of a terminal in a transport plane;
an identifier of said terminal in a signaling plane; and
at least one address of a quality of service and charging control entity in said network which manages said terminal,
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for a session involving said terminal to a gateway of the network in response to a request including the identifier of said terminal in the transport plane sent by said gateway; and
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for said session to an application entity in response to a request including the identifier of said terminal in the signaling plane sent by said application entity.
6. A computer program including instructions for executing a method of obtaining an address when said program is executed by a computer wherein said method of obtaining an address comprises sending a request, including at least one identifier of a requesting terminal, to a database comprising a component configured to store at least one record including:
an identifier of a terminal in a transport plane;
an identifier of said terminal in a signaling plane; and
at least one address of a quality of service and charging control entity in said network which manages said terminal,
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for a session involving said terminal to a gateway of the network in response to a request including the identifier of said terminal in the transport plane sent by said gateway; and
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for said session to an application entity in response to a request including the identifier of said terminal in the signaling plane sent by said application entity.
7. A computer-readable storage medium storing a computer program comprising instructions for executing a method of obtaining an address wherein said method of obtaining an address comprises sending a request, including at least one identifier of a requesting terminal, to a database comprising a component configured to store at least one record including:
an identifier of a terminal in a transport plane;
an identifier of said terminal in a signaling plane; and
at least one address of a quality of service and charging control entity in said network which manages said terminal,
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for a session involving said terminal to a gateway of the network in response to a request including the identifier of said terminal in the transport plane sent by said gateway; and
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for said session to an application entity in response to a request including the identifier of said terminal in the signaling plane sent by said application entity.
8. A database accessible in an IMS network, said database being configured to store at least one record including:
an identifier of a terminal in a transport plane;
an identifier of said terminal in a signaling plane; and
at least one address of a quality of service and charging control entity in said network,
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for a session involving said terminal to a gateway of the network in response to a request including the identifier of said terminal in the transport plane sent by said gateway; and
wherein the database is configured to send a message including said at least one address of the quality of service and charging control entity for said session to an application entity in response to a request including the identifier of said terminal in the signaling plane sent by said application entity.
9. The database according to claim 8 , wherein said record further includes a session identifier.
10. The database according to claim 8 , wherein said record further includes service information on a session in said network.
11. The database according to claim 8 , comprising means for obtaining service information on a session in said network by interrogating a quality of service and charging control entity in said network.
