Problems solved by technology
In this way, the relay user device will face the problem of power consumption / waste, and the wireless resources of the LTE network are likely to be inefficiently used, especially when the nearby remote user device does not need to use the nearby When serving the service user device to the network relay
[0004] On the other hand, when the remote user device or the relay user device moves, the ProSe UE-to-network relay service between the two ProSe UE-to-network relays may face disconnection

The invention discloses a mobile communication device having a wireless transceiver and a controller and a service continuity method. The communication device is disposed in a signal coverage range of a service network, and is used as a relay user device to provide network relay service for an adjacent service user device. The wireless transceiver device is used to execute the wireless transmission and the wireless receiving between the service network and a long-distance user device out of the signal coverage range of the service network. The controller is used to receive measurement report information from the long-distance user device by the wireless transceiver. When the measurement report information indicates that the connecting state between the long-distance user device and the mobile communication device is lower than a preset threshold, the wireless transceiver is used to transmit searching information to other relay user devices to trigger other relay user devices to start transmission of device-to-device synchronization signals.
Description
technical field [0001] The present invention mainly relates to wireless communication technology, and in particular to a service continuation method suitable for Proximity-based Service (Proximity-based Service, ProSe) User Equipment (UE) to network relay (UE-to-network relay). Background technique [0002] In recent years, due to the substantial increase in the public's demand for ubiquitous computing and network communication, various wireless technologies have come out, including: Global System for Mobile Communications (Global System for Mobile communications, GSM) technology, General Packet Wireless Service (General Packet Radio Service (GPRS) technology, Enhanced Data rates for Global Evolution (EDGE) technology, Wideband Code Division Multiple Access (WCDMA) technology, Code Division Multiple Access- 2000 (Code Division Multiple Access 2000, CDMA-2000) technology, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, Worldwide Interoperability...
