The present invention will be described in further detail with reference to examples.
For the following description, a communication architecture of a current mobile terminal will be described. Fig. 1 is a schematic diagram of a communication architecture of a mobile terminal according to an embodiment of the present invention; as shown in figure 1 of the drawings, in which,
the communication architecture of mobile terminals such as mobile phones supporting the fifth generation mobile communication technology (5G) can be basically divided into two parts, one part is a fourth generation mobile communication technology (4G) communication module, and the other part is a 5G communication module; the 5G communication module can be divided into a single-transmitting state and a double-transmitting state;
in the single-transmission state, 1 Power Amplifier (PA) and 4 Low Noise Amplifiers (LNA) in the 5G communication module need to be called, and the called is 1Tx 4 Rx;
the dual transmit state calls 2 PAs and 4 LNAs in the 5G communication module, which is denoted as 2Tx 4 Rx.
Fig. 2 is a flowchart illustrating a communication handover method according to an embodiment of the present invention; as shown in fig. 2, the communication switching method is applied to a terminal; the method comprises the following steps:
step 201, calling a monitoring component set under the condition that the first communication card is in a communication state;
step 202, monitoring the communication quality of the second communication card by using the monitoring component set;
and 203, selecting the second communication card for data communication when the second communication card meets a preset switching condition according to the communication quality of the second communication card.
The first communication card can be applied to (or work on) 5G frequency band signals, 4G frequency band signals and the like; the second communication card can be applied to 5G frequency band signals, 4G frequency band signals and the like.
When the first communication card is applied to a 5G frequency band signal, the first communication card can be specifically divided into a single transmission state and a double transmission state; here, the single transmission state refers to the above-mentioned 1Tx 4Rx, and the dual transmission state refers to 2Tx 4 Rx.
In one embodiment, the communication state of the first communication card includes: a single-shot state;
the call monitoring component comprises: calling a first communication module as a monitoring component set;
the first communication module realizes communication under a first class of frequency band signals; the monitoring component set is used for monitoring the communication quality of the second communication card applied to the first class frequency band signals.
Here, the first communication module is a 4G communication module; a first class of frequency band signals comprising: 4G frequency band signals and 5G damping frequency band signals.
Namely, when determining that the communication quality of the second communication card under the 4G frequency band signal and the 5G damping frequency band signal needs to be monitored, the 4G communication module may be invoked.
Accordingly, the communication quality may be characterized by the received signal strength. Specifically, the rf transceiver receives and demodulates the Signal, and during this process, the Reference Signal Receiving Power (RSRP) of the received Signal can be monitored as a basis for determining the strength of the Signal.
The determining that the second communication card satisfies the preset switching condition may include: determining that the signal strength of the second communication card is higher than the signal strength of the first communication card.
In one embodiment, the communication state of the first communication card includes: a single-shot state; the second communication card corresponds to a 5G frequency band signal;
the call monitoring component comprises:
after a first communication component set used by the first communication card is adjusted to a second communication component set, calling a PA (Power amplifier) and an LNA (Low noise amplifier) as a monitoring component set;
the monitoring component set is used for monitoring the communication quality of the second communication card applied to a second type of frequency band signals; the second type of frequency band signal is different from the first type of frequency band signal.
Here, the second type of frequency band signal includes: 5G band (i.e., sub-6G band) signals.
Wherein the first set of communication components comprises: 1 PA and 4 LNAs; the second set of communication components comprising: 1 PA and 2 LNAs;
after the first communication component set used by the first communication card is adjusted to the second communication component set, calling a PA and an LNA as the monitoring component set, including:
after adjusting the 1 PA and 4 LNAs used by the first communication card to use 1 PA and 2 LNAs, call 1 PA and 2 LNAs as a set of monitoring components.
Here, after calling 1 PA and 2 LNAs as a monitoring component set, monitoring the communication quality of the second communication card by using the monitoring component set; according to the communication quality of the second communication card, when the second communication card meets a preset switching condition, the second communication card is selected for data communication; and when the second communication card is determined not to meet the preset switching condition, continuing to use the first communication card for communication, and recovering from 1Tx2Rx to 1Tx 4Rx, namely recovering to use 1 PA and 4 LNAs by the first communication card.
Specifically, in the independent networking (SA) mode, the first communication card may perform 2 actions when the single-transmission SA operates (i.e., is in the single-transmission state), which are:
the first is the operation executed when the second communication card adopts 4G frequency band signals or 5G damping frequency band signals; the method comprises the following steps: and the periodic enabling 4G module monitors the second communication card, and when the signal intensity and/or the data transmission quantity and the like of the second communication card are better than the current use frequency band of the first communication card, the second communication card is switched to carry out data transmission by using the second communication card.
Second, the operation executed when the second communication card adopts the 5G frequency band (specifically, sub-6G frequency band) signal; the method comprises the following steps: the single transmission state is switched periodically, namely, the 1Tx 4Rx is switched to the 1Tx2Rx, and meanwhile, the other path of PA is opened to be 1Tx, so that the 1Tx2Rx is enabled to be used for monitoring the 5G frequency band signal of the second communication card; if the communication quality of the 5G frequency band signal of the second communication card is better than the frequency band used by the first communication card, switching the second communication card for data transmission; if the monitoring has no signal improvement, the first communication card is continuously used, and the 1Tx2Rx is restored to 1Tx 4 Rx.
It should be noted that, because the whole circuit design has 2Tx paths and 4Rx paths in total, 1Tx path (i.e., single transmission state) and 4Rx paths (i.e., 1T4R) are used when the first communication card single transmission SA operates in the initial state; when the 5G frequency band signal of the second communication card is to be detected, the 1T4R of the first communication card is switched to 1T2R (i.e. two Rx paths are cut off, only one Tx2Rx path is reserved for the first communication card), the remaining 2Rx paths are added with the unused 1Tx path for the 5G frequency band of the second communication card to be used, the second communication card is also 1T2R at this time, and the 1T2R is used to actually detect the performance of the second communication card.
It should be noted that, when the terminal is switched from 1T4R to 1T2R, the terminal may interact with the network side (i.e., the base station) to tell the base station that the terminal enters the handover state, so that the base station synchronously adjusts 1T2R of the adaptive terminal; similarly, when the monitoring process is completed, the target state (e.g., 1T4R state) is switched to in synchronization with the network.
In one embodiment, the communication state of the first communication card includes: a dual transmit state;
the call monitoring component comprises:
after the first communication component set used by the first communication card is adjusted to be a third communication component set, calling PA and LNA as a monitoring component set;
the monitoring component set is used for monitoring the communication quality of the second communication card applied to a second type of frequency band signals; the second type of frequency band signal is different from the first type of frequency band signal.
Wherein the first set of communication components comprises: 2 PAs and 4 LNAs; the second set of communication components comprising: 1 PA and 2 LNAs;
after the first communication component set used by the first communication card is adjusted to a third communication component set, calling a PA and a LNA as a monitoring component set, including:
after adjusting the 2 PAs and 4 LNAs used by the first communications card to use 1 PA and 2 LNAs, call 1 PA and 2 LNAs as a set of monitoring components.
Specifically, when the first communication card operates in dual-transmission SA (i.e., in a dual-transmission state), 2Tx paths and 4Rx paths (i.e., 2T4R) are used, and when a 5G frequency band (specifically, sub-6G frequency band) signal of the second communication card needs to be monitored, the 2T4R of the first communication card is switched to 1T2R (i.e., one Tx path and two Rx paths are cut off, only one Tx path and one Rx path are reserved for the first communication card SA), and the remaining 1Tx path and 2Rx paths are used for the 5G frequency band of the second communication card; at this time, the second communication card is also 1T2R, and the performance of the second communication card (such as RSRP signal quality, throughput and the like of the network where the frequency band of the second communication card is located) is actually monitored by using the 1T 2R; and if the communication quality of the second communication card is better than that of the first communication card, switching to the second communication card.
Here, the monitoring of the communication quality of the second communication card includes: performing data exchange with the base station for a certain period of time (a short time) through the second communication card to check the actual signal strength of the second communication card; such as detecting RSRP metrics, and looking at actual data throughput for a short period of time.
Specifically, after calling 1 PA and 2 LNAs as a monitoring component set, the method further includes:
monitoring the communication quality of the second communication card by using the monitoring component set;
according to the communication quality of the second communication card, when the second communication card meets a preset switching condition, the second communication card is selected for data communication;
and when the second communication card is determined not to meet the preset switching condition, continuing to use the first communication card for communication, and recovering from 1Tx2Rx to 2Tx 4Rx, namely recovering to use 2 PAs and 4 LNAs by the first communication card.
It should be noted that, when the terminal is switched from 2T4R to 1T2R, the terminal may interact with the network side (i.e., the base station) to tell the base station that the terminal enters a switching state, so that the base station synchronously adjusts 1T2R of the adaptive terminal; similarly, when the monitoring process is completed, the network is switched to the target state (e.g., 2T4R state) synchronously.
In one embodiment, the communication quality includes at least one of: signal strength, data transmission capacity, transmission rate, signal quality, throughput;
the determining that the second communication card meets a preset switching condition includes at least one of:
determining that the signal strength of the second communication card is higher than the signal strength of the first communication card;
determining that the data transmission amount of the second communication card is higher than that of the first communication card;
determining that the transmission rate of the second communication card is higher than the transmission rate of the first communication card;
determining that the signal quality of the second communication card is higher than the signal quality of the first communication card;
determining that the throughput of the second communication card is higher than the throughput of the first communication card.
In one embodiment, the first communications card may be in a 4G mode; in the case where the first communications card is in 4G mode, invoking a set of monitoring components comprising:
temporarily interrupting the 4G communication of the first communication card, and calling a 4G communication module as a monitoring component set; the monitoring component set is used for monitoring the communication quality of the second communication card applied to the first-class frequency band signals (namely 4G or 5G fading frequency band signals);
calling a 5G communication module as a monitoring component set; the monitoring component set is used for monitoring the communication quality of the second communication card applied to the second type of frequency band signals (namely 5G frequency band signals).
Specifically, corresponding to a frequency band signal of 4G or 5G refarming of the second communication card to be monitored, the 4G communication of the first communication card is temporarily interrupted, a (tune away) link is disconnected for communication with the second communication card, the communication quality (such as signal quality, throughput and the like) of the second communication card is analyzed, and whether switching is carried out or not is determined based on the signal quality, the throughput and the like;
corresponding to the need of monitoring the frequency band signal of the 5G (sub-6G) of the second communication card, because the first communication card only adopts the 4G communication module, the 5G communication module of the terminal is in an idle state, at the moment, only the 5G communication module needs to be called for the second communication card to use, and the state of the first communication card does not need to be disconnected.
The above embodiments are directed to a scheme with 2 PAs and 4 LNAs for a 5G communication module; in the case of a 5G communication module with more PAs and LNAs (e.g. 3 PAs and 6 LNAs, or 4 PAs and 8 LNAs, etc., which are not enumerated here), the following is further described with respect to invoking the monitoring component set:
for the above scheme that 1 PA and 2 LNAs are to be called as a monitoring component set after 1 PA and 4 LNAs used by the first communication card are adjusted to use 1 PA and 2 LNAs, the 1 PA and 2 LNAs can be called directly without adjusting the 1 PA and 4 LNAs used by the first communication card to use 1 PA and 2 LNAs.
Similarly, for the above-mentioned scheme that calls 1 PA and 2 LNAs as a monitoring component set after 2 PAs and 4 LNAs used by the first communication card are adjusted to use 1 PA and 2 LNAs, the 1 PA and 2 LNAs or 2 PAs and 4 LNAs can be called directly without first adjusting the 2 PAs and 4 LNAs used by the first communication card to use 1 PA and 2 LNAs.

a 5G communication mode comprising: single-emission SA operation and double-emission SA operation;
when the single-transmission SA works, if a 4G frequency band signal or a 5G fading frequency band signal (equivalent to the first-class frequency band signal) registered by the second communication card needs to be monitored, the 4G communication module is enabled to monitor the second communication card, and the monitoring determines that the communication quality (such as data transmission amount) of the second communication card is better than the current use frequency band of the first communication card, the second communication card is switched to perform data transmission by using the second communication card.
If a 5G frequency band signal (equivalent to the second frequency band signal) registered by the second communication card needs to be monitored, the single transmission state is periodically switched, that is, the 1Tx 4Rx is switched to the 1Tx2Rx, and meanwhile, the other path of PA is opened to be 1Tx, so that the 1Tx2Rx is enabled to monitor the 5G frequency band signal of the second communication card; if the communication quality of the 5G frequency band signal of the second communication card is better than the frequency band used by the first communication card, switching the second communication card for data transmission; if the monitoring has no signal improvement, the first communication card is continuously used, and the 1Tx2Rx is restored to 1Tx 4 Rx.
When the dual-transmission SA works, if a 5G frequency band (specifically, sub-6G frequency band) signal (equivalent to the second frequency band signal) registered by the second communication card needs to be monitored, the 1T4R of the first communication card is switched to 1T2R (i.e., two Rx paths are cut off, only one Tx2Rx path is reserved for the first communication card), the remaining 2Rx paths and the unused 1Tx path are added to the 5G frequency band of the second communication card for use, at this time, the second communication card is also 1T2R, and the 1T2R is used to actually monitor the communication quality of the second communication card.
If the registered 4G or 5G refarming frequency band signal of the second communication card (equivalent to the first class frequency band signal) needs to be monitored, the 4G communication module is called to carry out communication for the second communication card so as to monitor the signal quality of the second communication card.
In the 4G communication mode, if a 4G or 5G reframing frequency band signal (equivalent to the first class frequency band signal) registered by the second communication card needs to be monitored, the 4G communication of the first communication card is temporarily interrupted, and a tune away link is used for communicating with the second communication card so as to monitor the signal quality of the second communication card;
if a 5G frequency band (specifically, sub-6G frequency band) signal (equivalent to the second frequency band signal) of the second communication card needs to be monitored, since the first communication card only adopts the 4G communication module, the 5G communication module of the terminal is in an idle state, at this time, only the 5G communication module needs to be called for the second communication card to use, and the state of the first communication card does not need to be disconnected.
