Apparatus, and associated method, for notifying, delivering, and deleting media bursts communicated in a push-to-talk over cellular communication system
View Patent ↗Apparatus, and an associated method, for a PoC (Push-to-Talk over Cellular)-capable communication system. A user equipment PoC box is provided, and a corresponding network PoC box is also provided. A transport mechanism is defined and provided by which to communicate a PoC media burst that is delivered to a PoC box and stored thereat. Control functionality is provided by which to control disposition of the media burst, such as to make notification of a delivered media burst or to dispose of the media burst when no longer needed, is further provided.
1. A user equipment (UE) operable pursuant to a Push to talk Over Cellular (PoC) communication scheme, said UE comprising:
a client configured to receive, over a wireless access network, a PoC media burst from a PoC session, the PoC media burst being received in a multimedia message of a multimedia messaging service (MMS), the received multimedia message also including an identifier to identify the multimedia message as including PoC media burst data from the PoC session, and a copy of the PoC media burst and corresponding control data of the PoC session being stored at a network element;
a controller configured to:
provide an indication at the UE that indicates that the received multimedia message includes PoC media burst data from the PoC session; and
provide a capability at the UE for transmitting a control message of the MMS to the network element, the control message instructing the network element to delete the stored copy of the PoC media burst and the corresponding control data of the PoC session.
2. The UE of claim 1 wherein said client is further configured to store the PoC media burst received over the wireless access network.
3. The UE of claim 1 wherein the controller is further configured to provide an indication to a user of reception of the PoC media burst at the UE.
4. A method for facilitating communication of a push-to-talk Over Cellular (PoC) media burst, said method comprising:
receiving, over a wireless access network at a user equipment (UE), the PoC media burst from a PoC session, the PoC media burst being received in a multimedia message of a multimedia messaging service (MMS), the received multimedia message also including an identifier to identify the multimedia message as including PoC media burst data from the PoC session, and a copy of the PoC media burst and corresponding control data of the PoC session being stored at a network element;
storing the received PoC media burst;
providing an indication at the UE that indicates that the received multimedia message includes PoC media burst data from the PoC session; and
providing a capability at the UE for transmitting a control message of the MMS to the network element, the control message instructing the network element to delete the stored copy of the PoC media burst and the corresponding control data of the PoC session.
5. The method of claim 4 further comprising: supporting PoC session signaling associated with the PoC session in which the PoC media burst is communicated.
6. The method of claim 4 further comprising: supporting Media Burst Control procedures associated with communication of the PoC media burst.
7. The method of claim 4 further comprising: supporting Talk Burst Control procedures associated with communication of the PoC media burst.
8. A method of communicating media in a Push-to-Talk over Cellular (PoC) communication system, said method comprising:
forming, at a network element, a multimedia message of a multimedia messaging service (MMS), the multimedia message including a PoC media burst from a PoC session and an identifier identifying that the multimedia message includes PoC media burst data from the PoC session;
storing a copy of the PoC media burst and corresponding control data of the PoC session;
sending the multimedia message including the PoC media burst and the identifier over a wireless network to a user equipment (UE); and
providing for deletion of the copy of the PoC media burst and the corresponding control data of the PoC session stored at the network element in response to receiving a control message of the MMS over the wireless network from the UE.
9. The method of claim 8 wherein said sending the multimedia message further comprises:
extracting a delivery address out of a Session Initiation Protocol (SIP) message, and
populating a destination address field of the multimedia message with the delivery address.
