Control entity and method for setting up a session in a communications network, subscriber database and communications network
First Claim
1. A Control Entity for setting up a session in a communications network, comprisingan input device for receiving a request to set up a session in the communications network;
- a processor unit for processing the request; and
an output device for sending messages;
wherein the Control Entity further comprises or has access to a memory for storing information;
wherein the processor unit is arranged to;
determine if the request comprises a valid Communication Service Identifier (CSI), the CSI identifying the type of communication service of the session that is to be established over the communications network; and
if the request does not comprise a valid CSI, execute a default CSI procedure using default CSI information stored in the memory, said default CSI information being based upon subscription information;
wherein, for carrying out said default CSI procedure, said processor unit configured to;
add a default CSI to the request, in case the request does not comprise a CSI, where the default CSI is specified by the default CSI information;
ortest at least one parameter in the request and decide based on the at least one tested parameter and the default CSI information to add a default CSI to the request, where the default CSI is specified by the default CSI information, or not to add a default CSI to the request.

Abstract
Control entity and method for setting up a session in a communications network, subscriber database and communications network The invention relates to a control entity for setting up a session in a communications network, comprising an input device for receiving a request to set up a session in the communications network, a processor unit for processing the request, and an output device for sending messages. The control entity further comprising or having access to a memory for storing information. The processor unit is arranged to determine if the request comprises a valid Communication Service Identifier, CSI, the Communication Service Identifier identifying the type of communication service of the session that is to be established over the communications network. And if the request does not comprise a valid Communication Service Identifier to execute a default CSI procedure using default CSI information stored in the memory.

9. A method in a Control Entity in a communications network for setting up a session in a communications network, the method comprising:
-
receiving a request for setting up a session in the communications network; determining if the request comprises a valid Communication Service Identifier (CSI), the CSI identifying the type of communication service of the session that is to be established over the communications network; and if the request does not comprise a valid CSI, executing a default CSI procedure using default CSI information, said default CSI information being based upon subscription information; wherein said default CSI procedure comprises; adding a default CSI to the request, in case the request does not comprise a CSI, where the default CSI is specified by the default CSI information;
ortesting at least one parameter in the request and deciding based on the at least one tested parameter and the default CSI information to add a default CSI to the request, where the default CSI is specified by the default CSI information, or not to add a default CSI to the request. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An IP Multimedia Subsystem network, comprising a Control Entity for setting up a session in a communications network and a subscriber entity configured to be part of the communications network;
- and
wherein said Control Entity comprises; an input device for receiving a request to set up a session in the communications network; a processor unit for processing the request; and an output device for sending messages; wherein the Control Entity further comprises or has access to a memory for storing information; wherein the processor unit is arranged to; determine if the request comprises a valid Communication Service Identifier (CSI), the CSI identifying the type of communication service of the session that is to be established over the communications network; and if the request does not comprise a valid CSI, to execute a default CSI procedure using default CSI information stored in the memory, said default CSI information being based upon subscription information; wherein, for carrying out said default CSI procedure, said processor unit is configured to; add a default CSI to the request, in case the request does not comprise a CSI, where the default CSI is specified by the default CSI information;
ortest at least one parameter in the request and decide based on the at least one tested parameter and the default CSI information to add a default CSI to the request, where the default CSI is specified by the default CSI information, or not to add a default CSI to the request; wherein said subscriber database comprises; an input device for receiving a register message from a user terminal; a processor unit for processing the register message; and an output device; the subscriber database further comprising or having access to a memory for storing subscription information; wherein the subscriber database is configured to; generate default CSI information based upon subscription information stored in the memory, in reaction to the receipt of the register message; and transmit the generated default CSI information to at least one control entity in the communications network via the output device. - View Dependent Claims (17)
