Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The network switching method for terminal communication according to the embodiments of the present invention aims to solve the problem that when a terminal in the prior art includes multiple communication protocol networks, a latest communication protocol network is often preferred in consideration of speed of communication data, for example, a 4G communication network is preferred, when quality of the 4G communication network cannot meet communication requirements, a 3G communication network is selected, and when the 3G communication network cannot meet the communication requirements, a 2G communication network is selected. This has the advantage that the data communication speed of the communication can be ensured. However, when a user performs a voice call, if the latest communication protocol network is selected, a large power consumption loss may be caused, and therefore, it is necessary to provide a network switching method for terminal communication to reduce the terminal loss and improve the cruising ability.
In order to solve the above problem, the present invention provides a network switching method for terminal communication, where the method includes: when detecting that voice communication is carried out by using an FDD _ LTE network, a WCDMA network or a TDD _ LTE network, detecting whether a GSM network signal exists in the environment where the terminal is located; if the GSM network signal exists in the environment where the terminal is located, judging whether the GSM network signal value is larger than a preset signal threshold value; if the signal value of the GSM network is larger than the preset signal threshold value, intercepting a signal quality report of the currently used network sent to the base station by the terminal, and sending a pre-stored virtual network signal quality report to enable the network of the terminal for voice communication to be switched to the GSM network.
When the terminal uses an FDD _ LTE network, a WCDMA network or an FDD _ LTE network to carry out voice communication, other network signals of the environment where the terminal is located are detected, including GSM network signals, whether the GSM network signals meeting the communication requirements exist or not is judged, if the GSM network signals meeting the requirements exist, a signal quality report of the currently used network sent by each base station of the terminal is intercepted, a virtual signal quality report is sent, the network of the terminal for carrying out voice communication is switched to the GSM network, the terminal carries out voice communication in a more power-saving mode, electric energy is saved, and the endurance service time of the terminal is prolonged. The following description is made in detail with reference to the accompanying drawings.
The first embodiment is as follows:
fig. 1 shows an implementation flow of a network handover method for terminal communication according to a first embodiment of the present invention, which is detailed as follows:
in step S101, when detecting that voice communication is performed using an FDD _ LTE network, a WCDMA network, or TDD _ LTE, it is detected whether a GSM network signal exists in an environment where the terminal is located.
Specifically, the FDD _ LTE is FDD (Frequency Division duplex) in an LTE (Long Term Evolution, chinese is called all Long Term Evolution) mode, the WCDMA is Wideband Code Division Multiple Access, chinese is called all Wideband Code Division Multiple Access, TDD _ LTE is called all Time Division-synchronization Code Division Multiple Access, and chinese is called all Time Division-synchronization Code Division Multiple Access.
The terminal in the embodiment of the invention can be a communication terminal such as a smart phone, and the communication terminal at least comprises more than two communication modules, and the two communication modules consume different powers under the condition that the signal quality is basically the same when the two communication modules carry out voice communication.
Of course, when the terminal is in a data communication scenario, data transmission may be performed according to a network recommendation mode default by the system, for example, a communication protocol network with the fastest speed is preferentially adopted, or data transmission may be performed according to a communication protocol network set by the user.
Before implementing the embodiment of the present invention, the method may further include determining whether to turn on a power saving mode, if the power saving mode is not turned on, the power saving implementing steps described in steps S101 and S102 in the embodiment of the present invention are not entered, and if the power saving mode is turned on, when performing voice communication using an FDD _ LTE, WCDMA, or TDD _ LTE network, it is determined that a GSM network in an environment where the terminal is located exists and the signal quality is greater than a predetermined value.
In step S102, if a GSM network signal exists in the environment where the terminal is located, it is determined whether the GSM network signal value is greater than a preset signal threshold.
Specifically, the GSM is called Global System for Mobile Communication, and the chinese is called Global System for Mobile Communication.
The signal threshold is a threshold of network signal quality used for communication between the base station and the terminal. When the signal quality of the communication network is less than the threshold, the communication between the base station and the terminal is affected, that is, the terminal needs to consume more power to maintain the communication between the terminal and the base station, or even if more power is consumed, the communication between the terminal and the base station cannot be maintained.
At present, the experience of the terminal on data networking and video call through 4G _ LTE and 3G _ GSM signals is greatly superior to that of 2G _ TDD _ LTE signals; but the quality experience brought by 4G _ VoLTE and 3G _ TD-SCDMA is not very obvious for pure voice calls, or a small improvement in voice call quality.
In the initial stage of VoLTE, the following network systems generally exist in the terminal: 2G _ TDD _ LTE network, 3G _ GSM network, 4G can be one or two coexistent in FDD _ LTE network/WCDMA network; at present, the GSM call current is about 90 mA-250 mA, the WCDMA call current is about 100 mA-500 mA, the FDD _ LTE current is about 120 mA-600 mA, and the TDD _ LTE current is about 100-400 mA. It can be seen from the data that, under the same signal strength, the magnitude order of the call power consumption of each system is as follows: FDD _ LTE > WCDMA > TDD _ LTE > GSM.
In step S103, if the GSM network signal value is greater than the preset signal threshold, a signal quality report to the currently used network sent by the terminal to the base station is intercepted, and a pre-stored virtual network signal quality report is sent, so that the network where the terminal performs voice communication is switched to the GSM network.
In the embodiment of the invention, when the GSM network signal value is detected to be larger than the preset signal threshold value, a measurement report of the signal quality of the currently used network (FDD _ LTE, TDD _ LTE or WCDMA) which is fed back to the base station by the uplink of the terminal in real time is intercepted, and a pre-stored virtual signal quality report is sent.
The virtual network signal quality report may be arranged and combined according to the network in use and the detected network, and may be stored in advance in four types, which will be specifically described in the following embodiments.
The pre-stored quality report of the virtual network signal in the embodiment of the present invention includes two network signals, that is, a network in use by the terminal and a network detected to meet the communication requirement, where the network in use may be a WCDMA network, a TDD _ LTE network, or an FDD _ LTE network, and the network detected to meet the communication requirement may be a GSM network. And setting the signal quality value of the network in use to be less than a preset signal threshold value, and setting the detected signal quality of the network meeting the communication requirement to be greater than the preset signal threshold value.
And the base station switches the terminal to the detected network according to the received virtual network signal quality report and can switch to the detected network meeting the requirement because the data in the virtual network signal quality report is poor in signal quality of the currently used network and the detected network has better signal quality. Therefore, the terminal can carry out voice communication in a more energy-saving mode, and the service time of the terminal is prolonged.
Example two:
fig. 2 shows an implementation flow of a network handover method for terminal communication according to a second embodiment of the present invention, which is detailed as follows:
in step S201, when detecting that voice communication is performed using the FDD _ LTE network or the WCDMA network, it is detected whether a GSM network signal exists in the environment where the terminal is located.
In step S202, if a GSM network signal exists in the environment where the terminal is located, it is determined whether the GSM network signal is greater than a preset signal threshold.
In step S203, if the GSM network signal is greater than the preset signal threshold, a signal quality report of the currently used network sent by the terminal to the base station is intercepted, and a pre-stored virtual signal value including the currently used network and the GSM network is sent, so that the network where the terminal performs voice communication is switched to the GSM network.
In step S204, if there is no GSM network signal, or the GSM network signal is smaller than a preset signal threshold, it is determined whether there is a TDD _ LTE network signal.
In step S205, if a TDD _ LTE network signal exists and the TDD _ LTE network signal is greater than a preset signal threshold, a signal quality report of a currently used network sent by the terminal to the base station is intercepted, and a pre-stored virtual signal value including the currently used network and the TDD _ LTE network is sent, so that the network where the terminal performs voice communication is switched to the TDD _ LTE network.
In an actual network environment, because the TDD _ LTE signal coverage is much larger than that of a GSM signal, it is also necessary to see whether a GSM signal covers an actual network or not by selecting a GSM or TDD _ LTE call.
The embodiment of the invention is different from the first embodiment in that whether a GSM network signal exists in the environment where the terminal is located is preferentially detected, when the GSM signal meeting the requirement exists in the environment, the currently used network is switched to the GSM network, and if the GSM network meeting the requirement does not exist, whether a TDD _ LTE network meeting the requirement exists is detected, so that the invention can search the most energy-saving network, and can further reduce the power consumption of the terminal and improve the endurance service time of the terminal when the GSM network signal does not exist.
Example three:
fig. 3 shows an implementation flow of a network handover method for terminal communication according to a third embodiment of the present invention, which is detailed as follows:
preferentially configuring a plurality of virtual network signal quality reports reported back to the base station in a memory of the terminal, wherein the virtual network signal quality reports comprise:
reporting one: the method comprises the steps that virtual data containing FDD _ LTE network signal quality can meet the requirement that a base station initiates a command for switching from FDD _ LTE to a GSM network to a mobile phone;
report two: the method comprises the steps that virtual data containing TDD _ LTE network signal quality can meet the requirement that a base station initiates a command for switching from TDD _ LTE to a GSM network to a mobile phone;
report three: the virtual data containing WCDMA network signal quality can meet the requirement that the base station initiates a command for switching from WCDMA to GSM network to the mobile phone.
In step S301, the standby mobile phone maintains the state of the original operator network, and preferentially resides in the 4G _ LTE network, the 3G _ WCDMA network, and the 2G _ GSM network;
in step S302, when the user uses the data service, the network maintains the inherent network policy of the operator, and preferentially uses the 4G _ LTE network, then the 3G _ WCDMA network, and finally the 2G _ GSM network, so as to obtain better user experience;
in step S303, the user enters a pure voice call service (including an incoming call and an outgoing call), the mobile phone adds detection on the incoming and outgoing states of the voice call, and executes S304 operation after detecting the operation;
in step S304, when detecting that the voice service is in the incoming and outgoing state, the mobile phone first determines whether the voice call is currently in the GSM network, and if the determination result is "yes", does not perform any operation, and maintains the original network state; if the judgment is no, executing S305 operation;
in step S305, analyzing the current network information, and if the current network is determined to be FDD _ LTE, executing S306; if the current network is determined to be TDD _ LTE, then S307 is executed; if the current network is determined to be WCDMA, S308 is executed;
in step S306, an instruction is given to intercept an FDD _ LTE signal quality measurement report to be reported back to the base station by the mobile phone in the current state, and a prestored report one is called and reported back to the base station through an uplink, so that the base station initiates a command of switching FDD _ LTE to the GSM network, and the mobile phone is switched to the GSM network for conversation;
in step S307, an instruction is issued to intercept a TDD _ LTE signal quality measurement report to be reported back to the base station by the mobile phone in the current state, and a pre-stored report two is called and reported back to the base station through an uplink, so that the base station initiates a command for switching TDD _ LTE to the GSM network, and the mobile phone is switched to the GSM network for a call;
in step S308, an instruction is issued to intercept a WCDMA signal quality measurement report to be reported back to the base station by the mobile phone in the current state, and a prestored report is called, and the report is reported back to the base station through an uplink, so that the base station initiates a command of switching WCDMA to the GSM network, and the mobile phone is switched to the GSM network to perform a call;
in step S309, when the call is ended, and a call end state is detected, stopping sending the report data preset in the memory and stopping intercepting the current network data detected by the mobile phone;
through the process, the 4G/3G network with large call current is not used in the power-saving call mode through the setting of the mobile phone end, and the 2G _ GSM network is directly used for voice call, so that the call power consumption is greatly saved, and the cruising ability of the mobile phone is improved.
