Embodiment Construction

[0023] figure 1 is a partial schematic illustration of a cellular communication system 1 which is UMTS and GPRS compliant and contains UMTS and GPRS network elements.

[0024] A UMTS / GPRS cellular communication system 1 is shown providing service to a UE 2, which in this embodiment is a mobile phone. figure 1 The network elements of UE 2's home location and the network elements of UE 2's visited location are shown. exist figure 1 In , UE 2 is shown as currently at the visited location.

[0025] At the home location, the system 1 comprises a first Gateway GPRS Support Node (GGSN) 4 . Similarly, system 1 includes a first GGSN 6 at the visiting location. The system 1 also comprises a Serving GPRS Support Node (SGSN) 8 connected to the second GGSN 6 . The SGSN 8 performs a high-level handover, including determining the location of a particular UE by visiting a location register (not shown).

[0026] The system 1 also comprises a Radio Network Controller (RNC) 10 connected to...

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.

Description

technical field [0001] The present invention relates to voice messaging in cellular communication systems including, for example, the Universal Mobile Telecommunications System (UMTS), General Packet Radio Service (GPRS) and Global Mobile Telecommunications (GSM) systems. Background technique [0002] Cellular communication systems are well known. Examples of established tuned cellular radio communication systems are the Global Mobile Telecommunications (GSM) and General Packet Radio Service (GPRS) systems. A more tuned standard that is being introduced is the Universal Mobile Telecommunications System (UMTS). [0003] Such cellular communication systems allow conventional voice calls to be made and have subscriber units, such as mobile telephones, receive the voice calls. Furthermore, a further service called Short Message Service (SMS) allows other data to be sent or received. A common use of SMS is to send and receive text messages. Such text messages do not require t...
