Abstract
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.
Claims17
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.

A method operable on a wireless user equipment (UE) device operating in a wireless network environment, the method comprising:
- sending, using over-the-top (OtT) messaging, a call set-up request 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;
- responsive to receiving a rejection from the CSUF, sending a call set-up request to the mobile communications network, otherwise receiving information for setting up inter-device communications with the called wireless UE device sent from the network node using OtT messaging;
- responsive to obtaining the information for setting up inter-device communications with the called wireless UE device, establishing inter-device communications with the called wireless UE device;
- and
- initiating handover of the inter-device communications to another inter-device channel;
- 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 further 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.
3 more elements
A computer program product stored on a non-transitory computer readable media and operable for execution on a wireless user equipment (UE) device, the computer program product comprising:
- instructions for sending, using over-the-top (OtT) messaging, a call set-up request 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;
- instructions for sending a call set-up request to the mobile communications network responsive to receiving a rejection from the CSUF;
- instructions for receiving information for setting up inter-device communications with the called wireless UE device sent from the network node using OtT messaging;
- instructions for establishing 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;
- and
- instructions for initiating 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 and further 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 information for setting up the inter-device communications.
