Apparatus and method for selecting WPAN based adaptive RF interface

摘要

A method and apparatus for selecting a wireless personal area network (WPAN) based adaptive radio frequency (RF) interface. The method includes obtaining RF interface information by establishing a WPAN based network connection with a target RF device; selecting an RF interface from among a plurality of RF interfaces using the obtained RF interface information, based on characteristics of applications and a network load; and establishing the selected RF interface by negotiating about the selected RF interface with the target RF device.

1. A method of selecting a wireless personal area network (WPAN) based adaptive radio frequency (RF) interface, the method comprising:
establishing a network connection by performing WPAN discovery and pairing between a control RF device and a target RF device to establish a control channel, the establishing comprising receiving radio frequency for consumer electronics (RF4CE) nwkcNodeCapabilities information from the target RF device, wherein a reserved field of the nwkcNodeCapabilities information includes an indication of a type of RF interface supported by the target RF device; obtaining RF interface information from the received RF4CE nwkcNodeCapabilities information; selecting an RF interface from among a plurality of RF interfaces using the obtained RF interface information, based on characteristics of applications and a network load; establishing the selected RF interface with the target RF device; determining whether the RF interface is available according to a current availability status of the network; and searching for another RF interface by establishing the network connection and establishing the searched another RF interface with the target RF device based on the determining that the RF interface is unavailable; wherein the control channel is established by using an out-of-band control channel.
