Independent networking (SA) is an important networking mode in the 5G era and is a future trend, and operators explicitly require support of SA capability when manufacturers deliver goods. However, currently, the construction schedules of SA networks in different cities are different for each large operator, and the construction levels of busy commercial areas and residential areas in the same city are also different, so that a large number of SA weak coverage places exist, and a user can encounter more problems in the use process, thereby affecting the user experience and product public praise.

However, at present, terminal equipment manufacturers all follow the requirements of operators, and the SA capability is directly provided during shipment. The existing SA capability lacks flexible control and can encounter more problems. The main manifestations are that SA network can not register, basic functions (such as telephone and internet access) can not be performed, and even a certain power consumption problem is brought. These all give the user a bad experience and in severe cases cause complaints and back-offs of the network.

The invention provides a method for weak SA coverage, so that terminal equipment can register a proper cell more quickly to carry out normal service requirements, the complaint problem caused by the initial construction of an SA network in certain areas can be reduced, and the expressive force of the terminal equipment can be improved to a certain extent.

2) counter (counter): indicating the current failure times, and counting the times by the low layer failure to share one counter;

long _ monitor _ duration: indicating long monitoring time, at the current default time T3, the low layer failure is again bar after the cell (cell) is disabled (bar) and 1 or more times T3.

The technical solution of the present application is further described below by way of an embodiment, as shown in fig. 2, which is a schematic diagram of an embodiment of a method for weak coverage of independent networking in the embodiment of the present application, and the method may include:

201. under the condition that a first timer is not overtime, if N times of low-layer failures of the terminal equipment trying to access a candidate cell are detected, the candidate cell is set to a forbidden state, and a second timer is started, wherein N is a positive integer.

Optionally, under the condition that the first timer is not overtime, if it is detected that the terminal device attempts to access the candidate cell and N times of low-layer failures occur, setting the candidate cell in a disabled state, and starting the second timer, may include: under the condition that a first timer is not overtime, if N times of low-layer failures of the terminal device trying to access the candidate cell are detected, the candidate cell is set to be in a forbidden state, a second timer and a third timer are started, and the duration of the third timer is longer than that of the second timer.

Optionally, the low-level failure includes: any one of a T300 timeout, a radio link failure detection (RLF), and a Random Access Channel (RACH) failure.

Optionally, the scenario to which the method is applied includes at least one of the following: radio Resource Control (RRC) initially establishes, reconstructs, and switches scenarios.

Illustratively, the first timer corresponds to T1, the second timer corresponds to T2, the third timer corresponds to T3, T1 may be 150ms, T2 may be 300ms, and T3 may be 600 ms. The value of N may be 3. According to the cell disabling strategy for the SA weak coverage, when RRC is initially established, N times of low layer failure occur within T1 time, the detected candidate cell is set to be in a disabled state, and a second timer and a third timer are started. That is, it can be understood that the terminal device detects an abnormal scenario satisfying the disabled state, the bar cell duration T2 and the monitoring duration T3 are started, and T3 is greater than T2.

202. Maintaining the candidate cell in a disabled state if the second timer has not expired.

The maintaining the candidate cell in the disabled state if the second timer has not expired may include: and under the condition that the second timer is not overtime and the terminal equipment is in an idle (idle) state or a connected (connect) state, the terminal equipment keeps the candidate cell in a forbidden state.

Illustratively, if T2 has not timed out, in neither the idle state nor the connect state, the terminal device will not respond to the network event, i.e., the cell is always bar when T2 has not timed out.

203. Switching the candidate cell from the disabled state to a non-disabled state if the second timer expires.

Optionally, after the terminal device switches the candidate cell from the disabled state to the non-disabled state, the method further includes: and the terminal equipment retries to access the candidate cell in the non-forbidden state.

Optionally, when the second timer expires, the terminal device switches the candidate cell from the disabled state to a non-disabled state, which may include but is not limited to the following implementation manners:

mode 1: and if the second timer is overtime and the third timer is not overtime, if the terminal equipment detects that the candidate cell in the non-forbidden state is tried to be accessed by the terminal equipment and a low-layer failure occurs, the terminal equipment sets the candidate cell in the non-forbidden state to be in the forbidden state again, and resets the second timer and the third timer.

Optionally, if it is detected that the terminal device attempts to access the candidate cell in the non-forbidden state and a low-layer failure occurs, the terminal device resets the candidate cell in the non-forbidden state to the forbidden state, and resets the second timer and the third timer, which may include: if detecting that one or more low-layer failures occur when the terminal equipment attempts to access the candidate cell in the non-forbidden state, the terminal equipment sets the candidate cell in the non-forbidden state to the forbidden state again, and resets the second timer and the third timer.

For example, if T2 times out, T3 does not time out, and at this time, the terminal device fails to perform low layer failure once again in the problem cell, the bar cell is reset, and T2 and T3 are re-timed.

Mode 2: and restarting the first timer and retrying to access the candidate cell under the condition that the second timer is overtime and the third timer is overtime.

Optionally, the restarting, by the terminal device, the first timer to retry attempting to access the candidate cell may include: and the terminal equipment restarts the first timer, retries the attempt to access the candidate cell and detects the low-layer failure.

Illustratively, if T2 times out, T3 times out, and no low layer failure occurs again in the problem cell, the judgment of the problem scene is restarted. Then, the access to the problem cell can be retried, and whether the low layer failure occurs or not can be detected.

Optionally, the method further includes: and under the condition of triggering network re-searching, the terminal equipment switches the candidate cell from the forbidden state to the non-forbidden state and tries to access the candidate cell in the non-forbidden state.

Optionally, the network re-searching scenario may include: the terminal equipment is in a scene of a flight mode or a switching network mode.

Optionally, the method further includes: and if the terminal equipment switches the candidate cell in the forbidden state to the non-forbidden state, the candidate cell trying to access the non-forbidden state has low-layer failure, and the second timer is not overtime, the candidate cell in the non-forbidden state is set to the forbidden state again, and the second timer and the third timer are restarted.

Optionally, if the terminal device switches the candidate cell in the disabled state to the non-disabled state, the terminal device attempts to access the candidate cell in the non-disabled state once, and if a low layer failure occurs and the second timer is not timed out, the terminal device re-sets the candidate cell in the non-disabled state to the disabled state, and restarts the second timer and the third timer.

Illustratively, when the operation such as the flight mode or the network switching mode triggers network searching again, the terminal device is allowed to retry the network searching of the cell currently carried out by the bar once, if the network searching still has low layer failure and T2 does not time out, the bar cell is restarted, and T2 and T3 are restarted.

Optionally, the method further includes: and after the terminal equipment is restarted, clearing the information of the first timer, the second timer, the third timer, the counter and the candidate cell in the forbidden state, wherein the counter is used for counting the number of times of the low-layer failure.

For example, after the terminal device is restarted, the timers T1, T2, T3, the counter and the bar cell information are all cleared.

In the embodiment of the application, under the condition that a first timer is not overtime, if it is detected that the terminal device attempts to access a candidate cell and N times of low-layer failures occur, the candidate cell is set to a forbidden state, and a second timer is started, wherein N is a positive integer; maintaining the candidate cell in a disabled state if the second timer has not expired; switching the candidate cell from the disabled state to a non-disabled state if the second timer expires. Namely, when the SA network is not completely constructed, the problem cell or the weak coverage cell can be forbidden quickly, bad experience caused by network problems is reduced, and a user can be ensured to register a better cell quickly, so that normal service is carried out. Meanwhile, network complaints and market quit caused by SA problems can be reduced.

The counter can be shared for low layer failure, so that the weak coverage cell and the problem cell can be forbidden quickly; the parameter values mentioned in the application can be flexibly customized. The embodiment of the application can be applied to a scene during initial establishment of RRC and also can be applied to a low layer failure scene triggered in the process of reconstruction and switching, and is not particularly limited.

Referring to fig. 4, the handset includes: radio Frequency (RF) circuit 410, memory 420, input unit 430, display unit 440, sensor 450, audio circuit 460, wireless fidelity (WiFi) module 470, processor 480, and power supply 490. Those skilled in the art will appreciate that the handset configuration shown in fig. 4 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 4:

the RF circuit 410 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 480; in addition, the data for designing uplink is transmitted to the base station. In general, the RF circuit 410 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 410 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory 420 may be used to store software programs and modules, and the processor 480 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 420. The memory 420 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 420 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 430 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 430 may include a touch panel 431 and other input devices 432. The touch panel 431, also called a touch screen, may collect touch operations of a user on or near the touch panel 431 (e.g., operations of the user on or near the touch panel 431 using any suitable object or accessory such as a finger or a stylus) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 431 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 480, and receives and executes commands sent from the processor 480. In addition, the touch panel 431 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 430 may include other input devices 432 in addition to the touch panel 431. In particular, other input devices 432 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 440 may be used to display information input by the user or information provided to the user and various menus of the cellular phone. The Display unit 440 may include a Display panel 441, and optionally, the Display panel 441 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 431 may cover the display panel 441, and when the touch panel 431 detects a touch operation on or near the touch panel 431, the touch panel is transmitted to the processor 480 to determine the type of the touch event, and then the processor 480 provides a corresponding visual output on the display panel 441 according to the type of the touch event. Although the touch panel 431 and the display panel 441 are shown in fig. 4 as two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 431 and the display panel 441 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 450, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 441 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 441 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuit 460, speaker 461, microphone 462 may provide an audio interface between the user and the cell phone. The audio circuit 460 may transmit the electrical signal converted from the received audio data to the speaker 461, and convert the electrical signal into a sound signal for output by the speaker 461; on the other hand, the microphone 462 converts the collected sound signal into an electrical signal, which is received by the audio circuit 460 and converted into audio data, which is then processed by the audio data output processor 480 and then transmitted to, for example, another cellular phone via the RF circuit 410, or output to the memory 420 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 470, and provides wireless broadband Internet access for the user. Although fig. 4 shows the WiFi module 470, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 480 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 420 and calling data stored in the memory 420, thereby integrally monitoring the mobile phone. Optionally, processor 480 may include one or more processing units; preferably, the processor 480 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 480.
