Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, or apparatus.
The embodiment of the invention provides a network access control method and equipment, when a voice signal of VoLTE interferes with a signal of WIFI, voice service is returned to a data exchange network to avoid adjacent frequency band interference of the LTE signal and the WIFI signal, so that the quality of WIFI data transmission and voice communication is ensured. The following are detailed below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling network access according to an embodiment of the present invention. The method for controlling network access shown in fig. 1 may include the following steps:
101. and monitoring whether the terminal equipment has a voice signal access request of voice over LTE VoLTE.
In the embodiment of the present invention, the terminal device may be a smart phone, a smart watch, a palm computer, a tablet computer, a Personal Digital Assistant (PDA), a Point of Sales (POS), or the like, and the following description of the embodiment of the present invention will not be repeated.
102. And if so, judging whether the signal of the wireless fidelity WIFI network of the terminal equipment is deteriorated.
In the embodiment of the invention, as the voice call of the VoLTE is carried out through the LTE network, the frequency range of the B40 frequency band in the available frequency band of the LTE is 2300 plus 2400MHz, while the frequency range commonly used by the WIFI service at present is 2.4G frequency band, and the frequency range is 2403 plus 2481 MHz. As can be seen from the above-mentioned frequency ranges, there is no reasonable width inter-band partition between the upper band of the B40 frequency band and the lower band of the 2.4G frequency band of WIFI, and the application locations are both in the indoor environment, so in the actual user application scenario, the signals of the two bands are likely to generate inter-band interference, thereby reducing the communication quality. Therefore, if the terminal device has a voice signal access request of VoLTE and simultaneously the signal of the WIFI network of the terminal device is degraded, the frequency band currently applied by VbLTE may be the B40 frequency band, and the signal of the WIFI network is degraded due to the inter-band interference with the WIFI signal.
103. And if so, returning from the packet switching network of the VoLTE to the circuit switching network so as to finish the voice call of the voice signal access request.
In the embodiment of the present invention, the circuit-switched network includes a voice service network of a second generation mobile communication technology 2G and a voice service network of a third generation mobile communication technology 3G, and frequency bands applied by the two networks and a 2.4G frequency band of WIFI have a certain frequency band interval, so that inter-cell interference is not generated.
As an optional implementation manner, the terminal device uses a circuit domain fallback CSFB technique to fallback to the circuit switched network to complete the voice call of the voice signal access request;
as an optional implementation manner, the terminal device uses a dual-mode single-standby wireless voice call continuous SRVCC technology to fallback to the circuit switched network, so as to complete the voice call of the voice signal access request.
As an optional implementation manner, the terminal device selects a network system and a frequency band supported by both a hardware of the terminal device and a currently registered operator of the terminal device in the 2G voice service network or the 3G voice service network to perform network access, so as to complete the voice call of the voice signal access request.
Therefore, with the method described in fig. 1, when the voice signal of VoLTE interferes with the signal of WIFI, the voice service is returned to the data exchange network to avoid the interference of adjacent frequency bands of the LTE signal and the WIFI signal, so as to ensure the quality of WIFI data transmission and voice call.
Referring to fig. 2, fig. 2 is a flowchart illustrating another method for controlling network access according to an embodiment of the present invention. As shown in fig. 2, the method may include the steps of:
201. and monitoring whether the terminal equipment has a voice signal access request of voice over LTE VoLTE.
202. And if so, judging whether the signal of the wireless fidelity WIFI network of the terminal equipment is deteriorated.
In the embodiment of the present invention, if the terminal device has a voice signal access request of VoLTE, and at the same time, a signal of the WIFI network of the terminal device is degraded, a frequency band applied by VoLTE may be a B40 frequency band, and the signal of the WIFI network is degraded due to inter-band interference with the WIFI signal. Wherein the WIFI network of the terminal device comprises a WIFI network provided by the terminal device connected with other devices (such as a wireless router and the like) and also comprises a WIFI network shared by the terminal device as a hotspot to other devices,
203. and if so, returning from the packet switching network of the VoLTE to the circuit switching network so as to finish the voice call of the voice signal access request.
In the embodiment of the present invention, the circuit-switched network includes a voice service network of a second generation mobile communication technology 2G and a voice service network of a third generation mobile communication technology 3G, and frequency bands applied by the two networks and a 2.4G frequency band of WIFI have a certain frequency band interval, so that inter-band interference is not generated.
As an optional implementation manner, the terminal device uses a circuit domain fallback CSFB technique to fallback to the circuit switched network to complete the voice call of the voice signal access request;
as an optional implementation manner, the terminal device uses a dual-mode single-standby wireless voice call continuous SRVCC technology to fallback to the circuit switched network, so as to complete the voice call of the voice signal access request.
As an optional implementation manner, in the 2G voice service network or the 3G voice service network, the network system and the frequency band that the terminal device has access to are selected from the network systems and frequency bands that are supported by both the hardware of the terminal device and the operator currently registered by the terminal device, so as to complete the voice call of the voice signal access request.
In the embodiment of the invention, the terminal equipment is pre-stored with historical network access records, and when the frequency band which is accessed once is searched, the frequency band which is accessed once is preferentially accessed. The frequency band is successfully accessed before, so that the frequency band has higher probability of being successfully accessed at this time, and the selection is favorable for improving the network access rate and reducing the time consumed by network search.
204. And monitoring whether the terminal equipment is disconnected with the WIFI network or not.
205. And if so, re-accessing the packet switching network to complete the voice call by using VoLTE.
In the embodiment of the invention, if the connection of the WIFI network is disconnected, the voice call service is considered to be switched back to the packet switching network again, so that the voice service with better call quality is provided for the user by using the VoLTE. The disconnection of the WIFI network comprises disconnection of the WIFI network provided by the terminal equipment and other equipment, and also comprises stopping of the terminal equipment as a hotspot to stop providing the WIFI network.
Therefore, with the method described in fig. 2, when the voice signal of VoLTE interferes with the signal of WIFI, the voice service is returned to the data exchange network to avoid the interference of adjacent frequency bands of the LTE signal and the WIFI signal, so as to ensure the quality of WIFI data transmission and voice call. In addition, the terminal equipment preferentially selects the network system and the frequency band which are accessed once for access, which is beneficial to improving the network access rate and reducing the time consumed by network search.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a control device 100 for network access according to an embodiment of the present invention. The LTE frequency band selection device may be a dedicated chip for implementing frequency band selection in the terminal device, an application program with a frequency band selection function, or an external control device independent of the terminal device, and the like, which implementation is specifically adopted is not limited in the embodiment of the present invention.
As shown in fig. 3, the control device 100 for network access may include:
the first monitoring unit 301 is configured to monitor whether the terminal device has a voice signal access request of voice over LTE VoLTE.
A determining unit 302, configured to determine whether a signal of the WIFI network of the terminal device is degraded when the terminal device has a voice signal access of VoLTE.
In the embodiment of the invention, if the terminal device has the voice signal access request of the VoLTE and the signal of the WIFI network of the terminal device is degraded, the frequency band applied by the VoLTE may be the B40 frequency band, and the signal of the WIFI network is degraded due to the inter-band interference with the WIFI signal.
The first switching unit 303 is configured to, when a signal of the WIFI network of the terminal device is degraded, fallback from the packet switched network of VoLTE to the circuit switched network to complete the voice call of the voice signal access request.

As an optional implementation manner, the first switching unit 303 utilizes a circuit switched fallback CSFB technique to fallback to the circuit switched network to complete the voice call of the voice signal access request;
as an alternative implementation manner, the first switching unit 303 uses a dual-mode single-standby wireless voice call continuous SRVCC technology to fallback to the circuit-switched network, so as to complete the voice call of the voice signal access request.
It can be seen that, with the control device 100 for network access described in fig. 3, when the voice signal of VoLTE interferes with the signal of WIFI, the voice service is returned to the data exchange network to avoid adjacent frequency band interference of the LTE signal and the WIFI signal, so as to ensure the quality of WIFI data transmission and voice call.

fig. 6 is a block diagram illustrating a partial structure of the terminal device 2, which is provided in the embodiment of the present invention and takes a mobile phone as an example. Referring to fig. 6, the handset includes: a Radio Frequency (RF) circuit 601, a memory 602, an input unit 603, a display unit 604, a sensor 605, an audio circuit 606, a wireless fidelity (WiFi) module 607, a processor 608, and a power supply 609. Those skilled in the art will appreciate that the handset configuration shown in fig. 6 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. 6:
the RF circuit 601 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 608; in addition, the data for designing uplink is transmitted to the base station. In general, the RF circuit 601 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 circuit 601 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 communications (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 602 may be used to store software programs and modules, and the processor 608 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 602.

Further, the memory 602 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 603 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.

Alternatively, the touch panel 6031 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 608, and can receive and execute commands sent by the processor 608. In addition, the touch panel 6031 can be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 603 may include other input devices 6032 in addition to the touch panel 6031.

Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 6041 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 6041 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.

The audio circuit 606 may transmit the electrical signal converted from the received audio data to the speaker 6061, and convert the electrical signal into a sound signal by the speaker 6061 and output the sound signal; on the other hand, the microphone 6062 converts a collected sound signal into an electric signal, receives the electric signal by the audio circuit 606, converts the electric signal into audio data, and outputs the audio data to the processor 608 for processing, and then transmits the audio data to, for example, another cellular phone via the RF circuit 601, or outputs the audio data to the memory 602 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 607, and provides wireless broadband internet access for the user. Although fig. 6 shows the WiFi module 607, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 608 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 602 and calling data stored in the memory 602, thereby performing overall monitoring of the mobile phone. Alternatively, processor 608 may include one or more processing units; preferably, the processor 608 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 608.
