Abstract
Method and network entities for enabling server allocation in an IMS-based Multimedia over IP network. The method includes receiving by a S-CSCF server of the network subscriber registration data, transmitting, by the S-CSCF server, information representative of subscriber data to a P-CSCF server and/or to an HSS for storing the information representative of the subscriber data in a memory by the P-CSCF server and/or by the HSS, and transmitting, by the S-CSCF server, a S-CSCF group address to the P-CSCF server and/or to the HSS, respectively, said S-CSCF group address being representative of a group of S-CSCF servers, the S-CSCF server being included in said group of S-CSCF servers.

A method for enabling server allocation in an Internet Protocol Multimedia Subsystem (IMS) based Multimedia over Internet Protocol (IP) network, the method comprising:
- receiving registration data at a first server of the network, upon registration of a subscriber in said network;
- receiving subscription data at the first server, upon registration of said subscriber in said network, the registration data and the subscription data together forming subscriber data for said subscriber;
- transmitting, by the first server, information representative of the subscriber data needed in the first server for originating session establishment from the subscriber, to a second server of the network, for storing by the second server of the information representative of the subscriber data;
- transmitting to a third server of the network, by the first server, the information representative of the subscriber data needed in the first server for originating or terminating session establishment with the subscriber, for storing by the third server of the information representative of the subscriber data;
- transmitting a server group address, by the first server, to each of the second and third servers, said server group address being representative of a group of servers that includes the first server.
A first server for use in an Internet Protocol Multimedia Subsystem (IMS) based Multimedia over Internet Protocol (IP) network, the first server comprising:
- a processor and a memory storing computer code for execution by the processor, wherein the computer code comprises instructions such that the first server is configured to:
- receive registration data of said subscriber and receive subscription data of said subscriber, upon registration of said subscriber with said network, the registration data and the subscription data together forming subscriber data of the subscriber;
- send, to each of a second server and a third server, a server group address and information representative of the subscriber data needed in the first server for originating session establishment from the subscriber, for storing the information representative of the subscriber data by the first server and the third server, respectively.
A second server for use in an Internet Protocol Multimedia Subsystem (IMS) based Multimedia over Internet Protocol (IP) network, the second server comprising:
- a processor and a memory storing computer code for execution by the processor, wherein the computer code comprises instructions such that the second server is configured to:
- receive a multimedia service request sent by a user equipment (UE), the multimedia service request being a session initiation message for initiating a communication session or a non-session related multimedia service transaction, said multimedia service request including a server group address;
- select a server for originating session establishment with a subscriber corresponding to the multimedia service request, on the basis of the server group address;
- include, in the multimedia service request, information representative of subscriber data associated with the UE;
- and
- send said multimedia service request, including the information representative of the subscriber data, to the selected server.
A third server for use in an Internet Protocol Multimedia Subsystem (IMS) based Multimedia over Internet Protocol (IP) network, the third server comprising:
- a processor and a memory storing computer code for execution by the processor, wherein the computer code comprises instructions such that the third server is configured to:
- receive a multimedia service request being a session initiation message associated with a subscriber;
- interrogate a second server to obtain a server group address and to obtain information representative of subscriber data of the subscriber;
- select a server on the basis of the server group address;
- include, in the session initiation message, the obtained information representative of the subscriber data;
- and
- send said session initiation message, including the obtained information, to the selected server.
