System and method for mobile network inter-device communications |
摘要 |
A network node, UE device and method for providing inter-device communications between wireless user equipment (UE) devices in a wireless communications network. Responsive to a request for call set-up and to a determination that the devices are local to each other, a band is allocated to the devices for inter-device communications. The call set-up function can be managed by a node in the wireless communications network, a network node outside of the wireless communications network or by a distributed function shared between a network node and an ad-hoc group of UE devices in a local area that are capable of inter-device communications. |

1. A wireless user equipment (UE) device comprising:
a component configured to send a call set-up request, using over-the-top (OtT) messaging, to a call set-up function at a network node that is outside both an access network and a core network with which the UE device is operating, the call set-up request designating a called wireless UE device; a component configured to send a call set-up request to the mobile communications network responsive to receiving a rejection from the CSUF; a component configured to receive information for setting up inter-device communications with the called wireless UE device sent from the network node using OtT messaging; a component configured to establish inter-device communications with the called wireless UE device responsive to obtaining the information for setting up inter-device communications with the called wireless UE device, wherein the inter-device communications uses a radio channel operating directly between the calling and called wireless UE devices and uses at least one of a different band, a different radio access technology, and a different network than that used for obtaining the information for setting up inter-device communications; and a component to initiate handover of the inter-device communications to another inter-device channel, wherein the component configured to receive information for setting up inter-device communications comprises a component configured to receive one of timing information and coding information for use in establishing inter-device communications with the called wireless UE device. |
