Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Example one

As shown in fig. 3, in this embodiment, a method for network handover based on a mobile terminal includes:

s10, acquiring the signal strength of each antenna receiving signal on the mobile terminal;

s20, judging whether the data volume of the data to be transmitted on the mobile terminal is smaller than a preset data volume threshold value or not;

if yes, S30, turning off the antenna with the signal strength lower than the preset signal strength threshold value;

and S40, transmitting the data to be transmitted through the residual antennas and the 4G network.

In this embodiment, when a small amount of data is transmitted, the antenna with poor signal quality is turned off, and data transmission is performed through the 4G network, so that the transmission rate is ensured, the number of the antennas is reduced, the power consumption of the terminal is reduced, the endurance time of the terminal is prolonged, and the user experience of the terminal equipment is improved.

In this embodiment, frequent switching of the 5G network may cause power consumption of the terminal to increase, and reduce the endurance time, and currently, from the perspective of the terminal user, if there is no large data volume for transmission, data transmission on the 4G network is enough to ensure the transmission rate and the transmission quality, so that the terminal may be allowed to stably transmit data on the 4G network instead of being frequently switched to the 5G network when data volume is small for transmission.

In this embodiment, the terminal of 5G supports diversity reception, there are 3 or 4 antennas in most frequency band reception, there are differences between the measured reception power and signal quality when several antennas are at different positions of the terminal, the terminal performs combination calculation on the measurement results of the antennas, then evaluates the calculated values, and reports to the network when the report criteria are met. If one or two of the antennas receive poor signals, the final calculation result is affected when the signals are combined and calculated, the network receives the calculated measurement result and decides to execute network switching, so that the terminal may be switched from a 4G network to a 5G network, and if frequent small data transmission exists, the terminal may be frequently switched to the 5G network, so that power consumption is caused.

In this embodiment, the received power and signal quality of the antenna may be degraded due to interference and other factors at different positions of the antenna at the terminal. When the terminal judges that the data amount is small, one or two receiving antennas with poor receiving signals can be closed according to the power, the signal quality and the like of the service cell received by the antennas in the period of time. Therefore, when the network issues the measurement configuration requirement, the terminal can only receive the stable receiving signals of the two antennas, and reports the measurement result after the receiving power and the signal quality are combined and calculated. The radio frequency receiving antenna is less, on one hand, power consumption can be saved, on the other hand, the network is switched to 5G infrequently during small data transmission, and therefore the purposes of reducing power consumption and prolonging endurance are achieved.

As shown in fig. 4, in this embodiment, after step S20, the method further includes:

if the data volume of the data to be transmitted on the mobile terminal is greater than the preset data volume threshold value, S22, switching the 4G network of the mobile terminal to the 5G network;

and S23, transmitting the data to be transmitted through the 5G network.

In this embodiment, when the data to be transmitted is large data volume, the data cannot be transmitted by using the 4G network, so as to avoid affecting the transmission rate and the transmission quality and affecting the user experience, at this time, the terminal needs to be switched to the 5G network to transmit the large data volume, and the radio frequency antenna needs to work effectively, thereby ensuring the data transmission rate.

As shown in fig. 5, in the present embodiment, the step S10 includes:

s11, measuring the power and the signal quality of the received signal of each antenna on the mobile terminal;

and S12, calculating the signal strength of the received signal of each antenna according to the power and the signal quality of the received signal of each antenna.

In this embodiment, when small data volume is transmitted, by closing the antenna with poor signal quality and transmitting data through the 4G network, while the transmission rate is ensured, the power consumption of the terminal is inevitably reduced due to the reduction of the number of antennas, the endurance time of the terminal is prolonged, and the user experience of the terminal equipment is improved.

As shown in fig. 6, in this embodiment, before the step S10, the method further includes:

and S01, receiving the radio resource control configuration information issued by the network terminal.

In this embodiment, after receiving RRC configuration information sent by the network, the terminal may measure signal power and signal quality of the serving cell and surrounding cells.

As shown in fig. 7, in this embodiment, before the step S22, the method further includes:

and S21, RRM measurement is carried out according to the signal strength of the received signal of each antenna, and the measurement result is reported to the network terminal.

In this embodiment, the network end decides whether to execute network handover according to the measurement result reported by the terminal.

an obtaining module 10, configured to obtain signal strength of a signal received by each antenna on a mobile terminal;

the determining module 20 is configured to determine whether a data amount of data to be transmitted on the mobile terminal is smaller than a preset data amount threshold;

and the small data volume transmission module 40 is used for transmitting the data to be transmitted through the residual antennas and the 4G network.

As shown in fig. 9, in this embodiment, the network switching apparatus based on a mobile terminal further includes:

the network switching module 50 is configured to switch the 4G network of the mobile terminal to the 5G network if the data amount of the data to be transmitted on the mobile terminal is greater than a preset data amount threshold;

and the large data volume transmission module 60 is used for transmitting the data to be transmitted through the 5G network.

As shown in fig. 10, in this embodiment, the obtaining module includes:

a measuring unit 11, configured to measure power and signal quality of a signal received by each antenna on the mobile terminal;

a calculating unit 12, configured to calculate a signal strength of the received signal of each antenna according to the power and the signal quality of the received signal of each antenna.

As shown in fig. 11, in this embodiment, the network switching apparatus based on a mobile terminal further includes:

the configuration module 70 is configured to receive radio resource control configuration information sent by a network.

In this embodiment, after receiving RRC configuration information sent by the network, the terminal may measure signal powers, signal qualities, and the like of the serving cell and surrounding cells, and the network determines whether to perform network handover according to a measurement result reported by the terminal.
