Method for selecting and establishing a D2D communication path in MTC capillary networks

摘要

A method for selecting and establishing a device-to-device (D2D) communication path in MTC capillary network, to be executed on an MTC device, is provided, including receiving a paging request; piggybacking the paging request into a probe/beacon signal and sending said probe/beacon signal piggybacked with said paging request to an MTC gateway, when said MTC device being configured to use said MTC gateway; determining a D2D link quality and report result to an eNB connected to said MTC gateway, when receiving a probe/beacon signal without paging response from said MTC gateway; and when receiving a probe/beacon signal with paging response from said MTC gateway: setting up a D2D communication link, when said received response indicating said probe/beacon signal with paging request being accepted, or, setting up a direct cellular connection when said received response indicating said probe/beacon signal with paging request being rejected.

1. A method for selecting and establishing a device-to-device (D2D) communication path in Machine-Type Communication (MTC) capillary network, executed on an MTC device, comprising:
receiving a paging request; piggybacking the paging request into a probe/beacon signal and sending said probe/beacon signal piggybacked with said paging request to an MTC gateway, when said MTC device being configured to use said MTC gateway; determining a D2D link quality and report result to an eNB connected to said MTC gateway, when receiving a probe/beacon signal without paging response from said MTC gateway; and when receiving a probe/beacon signal with paging response from said MTC gateway: setting up a D2D communication link, when said received response indicating said probe/beacon signal with paging request being accepted, or, setting up a direct cellular connection when said received response indicating said probe/beacon signal with paging request being rejected.
