Providing secondary coverage in a mobile communication system
First Claim
1. A method for a first mobile device to communicate with a second mobile device, the method comprising:
- transmitting, at the first mobile device, a first signal indicating an opportunity for the second mobile device to transmit a second signal, the first mobile device having primary coverage from a first access node of a mobile communication system, the second mobile device not having primary coverage from any access node of the mobile communication system;
receiving, at the first mobile device and in response to the first signal, the second signal from the second mobile device, wherein the second signal comprises a presence indication that indicates the second mobile device is requesting secondary coverage in the mobile communication system; and
reporting, from the first mobile device, the presence indication that indicates the second mobile device is requesting secondary coverage, wherein the presence indication is reported to a network node using an information element that indicates receipt of the presence.
