The embodiment of the present invention provides a method for starting a relay function. Preferably, the method is applied to the wireless network system 10 shown in FIG. 1 . Referring to FIG. 3 , the method includes the following steps:

301. The first user equipment determines whether the quality of service of the current network meets a specific condition.

Preferably, the first user equipment may be the first user equipment 101 in the wireless network system 10 shown in FIG.

Optionally, the first user equipment can determine whether the quality of service of the current network meets a specific condition in the following four manners. Of course, the description herein is merely illustrative and does not mean that the invention is limited thereto.

First, the first way

The first user equipment receives the configuration information sent by the base station, where the configuration information includes a first power threshold; the first user equipment measures the RSRP (Reference Signal Receiving Power) of the base station according to the configuration information; when the RSRP of the base station is less than the first power At the threshold, the first user equipment determines that the quality of service of the current network does not satisfy the specific condition.

Optionally, the configuration information further includes a second power threshold, where the first user equipment may measure the RSRP of other frequencies when the RSRP of the base station is less than the first power threshold; and when the RSRP of the other frequency is less than the second power threshold, the first user The device determines that the quality of service of the current network does not meet certain conditions, wherein the other frequencies do not include the frequencies used by the base station.

When the RSRP of the base station is smaller than the first power threshold, the signal quality between the first user equipment and the base station is poor. In this case, the first user equipment may use different frequency and different system transmission, for example, when the first user equipment is connected. 3G (The 3rd Generation Mobile Communication Technology) network signal quality is poor, you can switch to 2G (2-Generation Wireless Telephone Technology) network, if 2G network (corresponding to other The signal quality of the frequency RSRP is still poor. At this time, the first user equipment needs other user equipment to provide the relay service. Preferably, the first mode can be applied to the first application scenario or the second application scenario in the application scenario shown in FIG. 2, and of course, it can also be applied to other application scenarios. .

Optionally, after the first user equipment detects the radio link failure RLF, if the cell is not searched within the first duration, the first user equipment determines that the quality of service of the current network does not meet the specific condition.

Or, optionally, after the first user equipment detects the radio link failure RLF, if the cell is found in the first time period, the first user equipment performs an RRC (Radio Resource Control) connection establishment; After the first user equipment RRC connection establishment is not successful, the first user equipment determines that the current network quality of service does not meet the specific condition. Preferably, the second mode can be applied to the second application scenario or the fourth application scenario in the application scenario shown in FIG. 2, and of course, it can also be applied to other application scenarios. .

Third, the third way

After detecting the downlink out-of-synchronization N times, the first user equipment determines that the quality of service of the current network does not meet the specific condition, and N is an integer greater than 0. Preferably, the third mode can be applied to the second application scenario or the fourth application scenario in the application scenario shown in FIG. 2, and of course, it can also be applied to other application scenarios. .

When the first user equipment resides in the first cell, the first user equipment determines that the quality of service of the first cell does not meet the specific condition, and the first cell provides the limited service for the first user equipment. Here, it should be noted that the limited service refers to that the first cell can only provide communication for certain emergency situations for the first user equipment, and cannot provide normal communication for the first user equipment. Preferably, the fourth mode can be applied to the third application scenario in the application scenario shown in FIG. 2, and of course, it can also be applied to other application scenarios.

302. When the first user equipment determines that the quality of service of the current network does not meet the specific condition, the first user equipment starts the function of the relay service.

Optionally, in combination with the description of the first mode in the step 301, the configuration information may further include a third power threshold. Before the first user equipment starts the function of the relay service, the RSRP of the relay user equipment may also be measured. When the RSRP of the device is greater than the third power threshold, the first user equipment starts the function of the relay service. Further optional, configuration information The frequency of the relay service may also be included, and the first user equipment receives the relay service signal sent by the relay user equipment according to the frequency of the relay service included in the configuration information, and measures the power of the relay service signal.

In a preferred application scenario, the configuration information may include a first power threshold, a second power threshold, and a third power threshold. The first user equipment may measure the RSRP of the other frequency when the RSRP of the base station is less than the first power threshold; when the RSRP of the other frequency is less than the second power threshold, the first user equipment measures the RSRP of the relay user equipment; when the relay user equipment When the RSRP is greater than the third power threshold, the first user equipment starts the function of the relay service.

Optionally, before the first user equipment starts the function of the relay service, when the first user equipment determines that the uplink data needs to be sent, the first user equipment starts the function of the relay service.

Optionally, before the first user equipment determines whether the quality of service of the current network meets the specific condition, that is, before step 301, the first user equipment may send capability information to the base station, where the capability information is used to indicate that the first user equipment has the request to relay. The ability to serve.

Optionally, the function of the first user equipment to start the relay service may be a request for sending a relay service to the relay user equipment, or may be establishing a connection with the relay user equipment, or may be a relay. The user device sends data. In this regard, the invention is not limited.
