1. A method comprising:
- discovering, by a first user equipment (UE), a plurality of UE-to-Network relays available to the first UE, wherein the first UE is located outside a coverage area of a wireless communications network;
receiving, by the first UE, one or more capacity indications from the plurality of UE-to-Network relays;
selecting, by the first UE, a first UE-to-Network relay from the plurality of UE-to-Network relays to connect to the wireless communications network in accordance with a relay selection policy and the one or more capacity indications, wherein the one or more capacity indications indicates a number of additional connections the first UE-to-Network relay can accept, an indication of bandwidth available through the first UE-to-Network relay, or a combination thereof; and
connecting, by the first UE, to the first UE-to-Network relay using direct mode communications, wherein the first UE-to-Network relay connects the first UE to the wireless communications network for the first UE to access a Push-to-talk (PTT) service.

Abstract
An embodiment method includes discovering, by a user equipment (UE), a plurality of UE-to-Network relays available to the first UE. The UE is located outside a coverage area of a wireless communications network. The method includes receiving, by the first UE, one or more capacity indications from the plurality of UE-to-Network relays and selecting, by the first UE, a first UE-to-Network relay from the plurality of UE-to-Network relays to connect to the wireless communications network in accordance with a relay selection policy and the one or more capacity indications. The method includes connecting, by the first UE, to the first UE-to-Network relay using direct mode communications.

7. A method comprising:
-
participating, by a relay, in a first group communications session with a first plurality of UEs in a first region, wherein the first group communications session uses a multicast based off-network group call protocol over proximity based services (ProSe); bridging, by the relay, the first plurality of UEs with a second UE for the first plurality of UEs to participate in Push-to-Talk (PTT) group communications with the second UE, wherein the second UE is located in a second region different from the first region; and conveying, by the relay, signaling flows for the PTT group communications from the second UE to the first plurality of UEs through the first group communications session. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method comprising:
-
discovering, by a first user equipment (UE)-to-UE relay, a second relay in a first coverage area of the first UE-to-UE relay, wherein the first coverage area corresponds to a coverage range of direct mode communications with the first UE-to-UE relay; and providing, by the first UE-to-UE relay, a Push-to-Talk (PTT) service to a first UE in the first coverage area through the second relay, wherein the first UE is connected to first UE-to-UE relay using direct mode communications, wherein the PTT service comprises a communications session between the first UE and a second UE, and wherein the second UE is located outside of the first coverage area. - View Dependent Claims (14, 15, 16, 17, 18, 19)
