Abstract

A method of operating a cellular communications system, the method comprising a subscriber unit, e.g. mobile station or user equipment such as a mobile telephone, participating in a session context such as a session conference call that has been set up using a session initiation protocol such as Internet IP Session Initiation Protocol; a first user inputting a voice message to the subscriber unit; and the subscriber unit transmitting the voice message to a second user by means of the session context. The voice message is input on a push-to-talk basis and transmitted over a push-to-talk bearer path.

Claims

1. A method of operating a cellular communications system, the method comprising the steps of:

a subscriber unit of the cellular communications system participating in a set up of a session context using a session initiation protocol;

a first user inputting a voice message to the subscriber unit;

a voice message module converting the voice message to a data stream; and

the subscriber unit transmitting the data stream carrying the voice message to a second user by means of the session context without making a dedicated call, wherein the inputting, converting and transmitting steps are all performed within a single subsequent session.

2. A method according to claim 1, further comprising the subscriber unit initiating the session context using the session initiation protocol.

3. A method according to claim 1, wherein the voice message is input to the subscriber unit using a push-to-talk process.

4. A method according to claim 3, further comprising a push-to-talk bearer path being established from the subscriber unit to a gateway node, the voice message being transmitted over the push-to-talk bearer path.

5. A method according to claim 4, further comprising the gateway node performing push-to-talk to stream conversion.

6. A method according to of claim5 From 1, further comprising the step of compressing the voice message.

7. A method according to claim 1, wherein the session context is compliant with the Session Initiation Protocol, SIP, of the Internet Protocol, IP.

8. A method according to of claim 1, wherein the session context comprises use of the Multimedia Messaging, MMS, Presence service.

9. A cellular communications subscriber unit, comprising:

means for participating in a set up of a session context;

means for receiving an input voice message;

means for converting the voice message to a data stream; and

means for transmitting the data stream carrying the voice message by means of the session context without making a dedicated call, wherein the means for receiving, converting and transmitting are all performed within a single subsequent session.

10. A cellular communications subscriber unit according to claim 9, further comprising means for initiating the session context using a session initiation protocol.

11. A cellular communications subscriber unit according to claim 9, wherein the means for receiving an input voice message comprises push-to-talk means for receiving the input message by a push-to-talk process.

12. A cellular communications subscriber unit according to claims 9, further comprising means for compressing the voice message.

13. A cellular communications subscriber unit according to claim 9, wherein the session context is compliant with the Session Initiation Protocol, SIP, of the Internet Protocol, IP.

14. A cellular communications subscriber unit according to claims 9, wherein the session context comprises use of the Multimedia Messaging, MMS, Presence service.
