Abstract

A device for wirelessly communicating a service to user equipment is provided. The device includes a transmitter, a receiver, and a processor. The processor is programmed to promote the transmitter polling to determine whether user equipment desire a service and responsive to receiving, via the receiver, at least one user equipment request for the service, the processor programmed to promote the transmitter providing a point-to-multipoint (PTM) broadcast of the service.

Claims

1. A method comprising:

determining, by a user equipment (UE) in a wireless network, whether a service received via a broadcast signal is at a low quality;

requesting, by the UE, a point-to-point (PTP) communication of the service when the service received via the broadcast signal is at a low quality;

receiving, by the UE, substantially simultaneously the same service via the PTP communication and the broadcast signal; and

combining, by the UE, the service received via the broadcast signal with the service received via the PTP communication.

2. The method of claim 1, wherein the service comprises a multimedia broadcast multicast service (MBMS).

3. The method of claim 1, wherein the UE is one of the group consisting of mobile devices, mobile handsets, cellular telephones, mobile telephones, dual mode handsets, wireless telephones, laptop computer, tablet computers, portable computers, desktop and personal computers, televisions, set-top boxes, and personal digital assistants (PDAs).

4. The method of claim 1, wherein the combining increases quality of the service.

5. The method of claim 1, further comprising:

receiving, by the UE, a polling request regarding the service.

6. A method comprising:

transmitting, by a network element in a wireless network, a service via a point-to-multipoint (PTM) broadcast,

receiving, by the network element, a request to send the same service via a point-to-point (PTP) communication; and

transmitting, by the network element, the same service via a PTP communication such that the PTM broadcast and PTP communication occur substantially concurrently.

7. The method of claim 6, wherein transmitting, by the network element, the PTM broadcast of the service occurs when a user equipment (UE) requests the service.

8. The method of claim 6, wherein the service is a MBMS (multimedia broadcast multicast service.

9. The method of claim 6, further comprising:

transmitting, by the network element, a polling request regarding the service.
