Abstract

A method for establishing a radio connection includes selecting a first radio access technology for a first phase of a multi-phase radio connection establishment process to minimize power consumption at a remote device, and participating in the first phase of the multi-phase radio connection establishment process. The method also enables establishing and using a radio connection with the first radio access technology that is selected independently from a selection of a second radio access technology used in a second phase of the multi-phase radio connection establishment process, wherein the second phase may be relayed or direct data communications over the established connection in the first phase between the wearable device and its peer (relay) devices or network equipment.

First claim

What is claimed is:

1. A method for establishing radio connections, the method comprising:
selecting, by a first device in a multi-phase radio connection establishment process for establishing a radio connection, a respective radio connection technology from a plurality of different radio connection technologies for use in each of at least two phases of a plurality of phases in the multi-phase radio connection establishment process, the plurality of phases being predetermined and comprising a discovery trigger phase, a device discovery phase, and a connection setup phase, wherein the first device participates in each of the at least two phases; and
participating, by the first device, in a first phase of the at least two phases in the multi-phase radio connection establishment process using a first radio connection technology, wherein the first radio connection technology is selected by the first device for the first phase.

2. The method of claim 1 , wherein the first radio connection technology is selected in accordance with at least a performance requirement of the radio connection, a service requirement for using the radio connection, a configuration for the radio connection, resource availability for the radio connection, power consumption of a device involved in the multi-phase radio connection establishment process, an instruction from a device that is already connected to the first device using a different technology, or a radio connection technology supported by the first device and another device participating in establishing the radio connection.

3. The method of claim 1 , further comprising selecting, by the first device, a second radio connection technology from a plurality of radio connection technologies for a second phase of the multi-phase radio connection establishment process, wherein the second radio connection technology is selected independently from the first radio connection technology selected for the first phase of the multi-phase radio connection establishment process, or based at least in part on the first phase or the first radio connection technology.

4. The method of claim 3 , wherein the first radio connection technology selected for the first phase of the multi-phase radio connection establishment process is different from the second radio connection technology selected for the second phase of the multi-phase radio connection establishment process.

5. The method of claim 3 , wherein selection of the first radio connection technology in the first phase and selection of the second radio connection technology in the second phase occur sequentially or iteratively.

6. The method of claim 3 , wherein the first radio connection technology or the second radio connection technology comprises a 3GPP Long Term Evolution (LTE) compliant technology, a 3GPP 5G new radio (NR) compliant technology, a 3GPP infrastructure-based technology involving a remote base station, a 3GPP point-to-point technology, an IEEE 802.11 compliant technology, a Wi-Fi compliant technology, an IEEE 802.11 or Wi-Fi infrastructure-based technology involving an access point, an IEEE 802.11 or Wi-Fi point-to-point technology, an IEEE 802.15 or Bluetooth compliant technology, an IEEE 802.15 or Bluetooth Low Energy (BLE) compliant technology.

7. The method of claim 1 , wherein the plurality of phases of the multi-phase radio connection establishment process further comprise, an initial device discovery phase, an initial service discovery phase, a phase for discovering a second device, a phase for discovering service capability of the second device, a peer device or service pairing and authentication phase, a direct communication phase for communicating over the radio connection, or a relayed communication phase for communicating over the radio connection.

8. The method of claim 1 , wherein participating in the first phase of the multi-phase radio connection establishment process comprises exchanging messages in accordance with the first radio connection technology.

9. The method of claim 1 , wherein the radio connection is established between a second device and a third device through the first device as a relay, or the radio connection is established between the first device and the third device using the second device as a relay.

10. The method of claim 1 , wherein selecting, by the first device, the respective radio connection technology from the plurality of different radio connection technologies for each of the at least two phases comprises selecting the respective radio connection technology for an initial service and device discovery phase when being triggered by an event or instructed by a second device that is already connected to the first device through a selected or configured radio connection technology.

11. A first device, comprising:
a processor; and
a computer readable storage medium storing programming for execution by the processor, the programming including instructions to configure the first device to:
select a respective radio connection technology from a plurality of different radio connection technologies for use in each of at least two phases of a plurality of phases in a multi-phase radio connection establishment process for establishing a radio connection, the plurality of phases comprising a discovery trigger phase, a device discovery phase, and a connection setup phase, wherein the first device participates in each of the at least two phases; and

participate in a first phase of the at least two phases in the multi-phase radio connection establishment process using a first radio connection technology, wherein the first radio connection technology is selected by the first device for the first phase.

12. The first device of claim 11 , wherein the programming includes instructions to configure the first device to select the first radio connection technology in accordance with at least a performance requirement of the radio connection, a service requirement for using the radio connection, a configuration for the radio connection, resource availability for the radio connection, power consumption of a device involved in the multi-phase radio connection establishment process, an instruction from a device that is already connected to the first device using a different technology, or a radio connection technology supported by the first device and another device participating in establishing the radio connection.

13. The first device of claim 11 , wherein the programming includes instructions to configure the first device to select a radio access network for the first phase, and wherein the first radio connection technology is selected independently from a second radio connection technology selected by the first device for a second phase of the at least two phases in the multi-phase radio connection establishment process.

14. The first device of claim 11 , wherein the first device is a remote device, a relay device, or an access node.

15. The first device of claim 11 , wherein the programming includes instructions to configure the first device to exchange messages in accordance with the first radio connection technology.

16. The first device of claim 11 , wherein the first radio connection technology comprises a Third Generation Partnership Project (3GPP) compliant technology, or a non-3GPP compliant technology.

17. A non-transitory computer-readable medium storing programming for execution by a processor, the programming including instructions to:
select, for a first device in a multi-phase radio connection establishment process for establishing a radio connection, a respective radio co
