Methods and apparatus to facilitate device-to-device communication |
摘要 |
Methods and apparatus to facilitate device-to-device communication with a remote device registered with a communication network are described. One example method may include obtaining an identity information of the second device from an address book, submitting the identity information of the second device to a communication network, estimating device-to-device (D2D) proximity of the second device, generating an indication of the proximity of the second device relative to the first device, and initiating a device-to-device communication session with the second device when the indication is that the second device is proximate. |

1. A method to facilitate device-to-device communication between a first device and a second device, the method comprising:
obtaining an identity information of the second device from an address book; submitting the identity information of the second device to a communication network; estimating device-to-device (D2D) proximity of the second device; generating an indication of the D2D proximity of the second device relative to the first device; initiating a device-to-device communication session with the second device when the indication is that the second device is proximate; and sending Session Description Protocol (SDP) information to the second device containing SDP extensions for a Session Initiation (SIP) preconditions framework, wherein the SDP extensions indicate a precondition that a D2D link be established between the first and the second device. |
