Abstract

The subject matter described herein includes methods, systems, and computer readable media for providing services in a telecommunications network using an IOS/SIP adapter. According to one aspect of the subject matter described herein, a method for providing supplementary services to IMS devices and non-IMS devices using common IMS network components is provided. The method includes providing an interoperability specification/session initiation protocol (IOS/SIP) adapter configured to communicate with a base station subsystem and an IMS network. The method further includes, at the IOS/SIP adapter, receiving, from the base station subsystem a request for providing a supplementary service to a non-IMS device in communication with the base station subsystem. In response to the request, the method includes sending a message to an IMS node in the IMS network that provides the supplementary service to the non-IMS device and to IMS devices.

5. The method of claim 3 wherein the SIP message that furthers the providing of the supplementary service comprises an INVITE message.

6. The method of claim 4 wherein mapping parameters in the IOS message to corresponding parameters in the SIP message includes mapping IOS bearer parameters to SIP bearer parameters.

7. The method of claim 4 wherein mapping parameters in the IOS message to corresponding parameters in the SIP message includes mapping combinations of parameters and Sub-parameters in the IOS message to combinations of parameters and sub-parameters in the SIP message.

8. The method of claim 1 comprising registering the non-IMS device with the IMS network via the IOS/SIP adapter.

9. The method of claim 1 wherein the base station subsystem comprises one of a femto cell base station subsystem, a pico cell base station subsystem, a micro cell base station subsystem and a macro cell base station subsystem.

10. The method of claim 1 wherein the sending a message to the CSCF in the IMS network includes mapping parameters from the request from the base station subsystem to corresponding parameters in the message sent to the CSCF in the IMS network.

11. The method of claim 1 further comprising, at the IOS/SIP adapter, receiving a message from the IMS network regarding the supplementary service, formulating a corresponding IOS message, and sending the corresponding IOS message to the base station subsystem.

12. A method for call setup using an interoperability specification/session initiation protocol (IOS/SIP) adapter, the method comprising:

at the IOS/SIP adapter, receiving an IOS call setup request in response to a call originating from a non IP multimedia subsystem (non-IMS) device;

at the IOS/SIP adapter, in response to the IOS call setup request, formulating an IMS message for setting up the call in an IMS network, wherein the IMS message is a session initiation protocol (SIP) INVITE message that includes IOS mapped SIP bearer parameters mapped to IOS bearer parameters and is sent after radio resources are assigned by the base station subsystem, where the IMS message includes information for setting up the call, the information including at least the calling party identifier; and

sending the IMS message to a call session control function (CSCF) in the IMS network that provides call setup services for IMS and non-IMS devices.

13. The method of claim 12 wherein receiving an IOS call setup request includes receiving the IOS call setup request from one of a femto cell base station subsystem, a pico cell base station subsystem, a micro cell base station subsystem, and a macro cell base station subsystem.

14. The method of claim 12 wherein the IMS message includes information required for setting up the call.

15. The method of claim 12 wherein formulating the IMS message includes mapping parameters in the IOS call setup request to corresponding parameters in the SIP message.

16. The method of claim 12 comprising, at the IOS/SIP adapter, receiving a SIP message from the IMS network regarding the call, and, in response, formulating a corresponding IOS message and sending the corresponding IOS message to a base station subsystem.
