The following describes embodiments of the present application in detail.

Referring to fig. 5, fig. 5 is a schematic flowchart of a network release method provided in an embodiment of the present application, and is applied to a terminal device, where the terminal device supports a dual connectivity mode; in a dual connectivity mode, the terminal device connects a first communication network and a second communication network at the same time, where the first communication network is a primary communication network and the second communication network is a secondary communication network, including the following steps:

step 501: and acquiring the network transmission quality evaluation value of the terminal equipment.

The network transmission quality evaluation value is the network transmission quality which the terminal equipment needs to reach through the accessed communication network.

The network transmission quality evaluation value may be a data transmission rate, a data transmission total amount, a network delay, a throughput, a packet loss rate, a reference signal received power, and the like.

For example, if the network transmission quality assessment value is the total data transmission amount, and the total data amount is 200M, the terminal device needs to transmit data of the total data amount of 200M through the accessed communication network.

For example, if the network transmission quality evaluation value is a data transmission rate, and the data transmission rate is 2M/s, the terminal device needs to perform data transmission at the data transmission rate of 2M/s through the accessed communication network.

The network transmission quality evaluation values of different dual connectivity scenarios may be the same or different.

The terminal device can transmit signaling by using a first communication network and transmit data by using a second communication network.

Step 502: and if the network transmission quality evaluation value is smaller than a first threshold value, sending a measurement report to first access network equipment of the first communication network, wherein the measurement report is used for triggering the first access network equipment to send first indication information.

The first access network device sends a release instruction to the access network device of the second communication network before the terminal device sends the measurement report to the first access network device, or sends a release instruction to the access network device of the second communication network after sending the first measurement report, wherein the release instruction is used for instructing the access network device of the second communication network to release the context information associated with the terminal device.

The first threshold may be preset or may be specified by a protocol, and is not limited herein.

The first threshold values corresponding to different network transmission quality assessment values may be different or the same.

The network release method of the present application uses different dual connection scenarios, and the corresponding first thresholds may be the same or different.

Wherein the measurement report includes a communication quality assessment value of the second communication network.

The measurement report may be carried in a signaling sent by the terminal device to the first access network device, or may be carried in data sent by the terminal device to the first access network device, which is not limited herein.

Wherein, the measurement report occupies one bit, and the first access network equipment is indicated to send down the first indication information when the value of the 1 bit is 1; or, when the value of the 1 bit is 0, the first access network device is instructed to issue the first indication information. Of course, the measurement report may occupy more than one bit, and the indication of more than one bit is similar to the indication of 1 bit, and will not be described herein.

The terminal equipment further comprises a double-connection switch, the double-connection switch is used for switching on and off LTE and 5G double-connection functions, and the double-connection switch is in an on state before a measurement report is sent to the first access network equipment.

Step 503: and the terminal equipment receives the first indication information and releases the second communication network according to the first indication information.

One of the first communication network and the second communication network is an LTE network and is a 5G network, the first indication information occupies 1 bit, the LTE network is indicated to be released when the value of the 1 bit is 1, and the 5G network is indicated to be released when the value of the 1 bit is 0; or, when the value of the 1 bit is 0, the release of the LTE network is instructed, and when the value of the 1 bit is 1, the release of the 5G network is instructed. Of course, the first indication information may occupy a plurality of bits, and the indication of the plurality of bits is similar to the indication of the 1 bit, and will not be described herein.

After the second communication network is released, the terminal device sends a network release response to the first access network device to inform the first access network device that the second communication network is released.

In one implementation of the present application, the measurement report is the a2 event.

The measurement report is an a2 event, and in the standard protocol, the a2 event is used to indicate that the signal quality of the serving cell is lower than a set threshold.

Alternatively, the measurement report may be not the a2 event, but only one piece of information indicating that the network transmission quality assessment value of the terminal device is smaller than the first threshold.

It can be seen that, in the embodiment of the present application, the measurement report is an a2 event, and the terminal device may send the measurement report when the a2 event trigger condition is met, which is beneficial to reducing the time required by the terminal device to send the measurement report.

In an implementation of the present application, the measurement report is further used to indicate that the communication quality assessment value of the second communication network is less than a second threshold.

If the communication quality evaluation value of the second communication network is smaller than the second threshold, the communication quality of the second communication network cannot meet the requirement of the terminal device.

The second threshold may be preset or specified by a protocol, and is not limited herein.

The communication quality evaluation value may be a data transmission rate, a signal to interference plus noise ratio, a reference signal received power, a received signal strength indicator, or the like. The second threshold values are different for different communication quality evaluation values.

The network transmission quality evaluation and the communication quality evaluation may be performed on the same performance index or different performance indexes.

For example, network transmission quality assessment may be performed based on data transmission rate, and communication quality assessment may be performed based on data transmission rate; or, the network transmission quality evaluation may be performed based on the packet loss rate, and the communication quality evaluation may be performed based on the reference signal received power.

The network transmission quality evaluation value may be equal to or different from the communication quality evaluation value.

The first threshold and the second threshold may be equal or different.

It can be seen that, in the embodiment of the present application, the communication quality assessment value of the second communication network is smaller than the second threshold, which indicates that the second communication network cannot meet the requirement of the terminal device, and is beneficial to improving the accuracy of the terminal device in releasing the communication network with poor network quality.

In an implementation manner of the present application, the method further includes:

determining a data transmission rate of the second communication network based on a total data volume of the data transmitted by the terminal device using the second communication network;

and determining the network transmission quality evaluation value of the terminal equipment based on the data transmission rate.

Optionally, the total data volume of the data transmitted by the second communication network includes a first value and a second value, the first value is the total data volume sent by the terminal device using the second communication network in the first time period, and the second value is the total data volume received by the terminal device using the second communication network in the first time period.

The duration of the first time interval may be, for example, 2min, 4min, 5min, 9min, 15min, or another value, and the termination time of the first time interval is the current time.

Optionally, the determining a data transmission rate of the second communication network based on a total data amount of the data transmitted by the terminal device using the second communication network includes: determining a data transmission rate of the second communication network based on a first formula, the first value, and the second value.

Under the first task, the total data volume received by the terminal equipment and the total data volume sent by the terminal equipment are both larger than a first set value. The first task is, for example, voice chat, video chat, game, or other tasks that send and receive large amounts of data.

Wherein the first formula is: the speed is (a + B)/T1, where the speed is a data transmission rate, the T1 is a duration of the first time period, a is a total data amount sent by the terminal device using the communication network, and B is a total data amount received by the terminal device using the communication network.

For example, assuming that the duration of the first period is 1min, the first value is 8MB, and the second value is 10MB, the data transmission rate of the first communication network is [ (8+10) ]/1 is 18 MB/min.

Optionally, the determining a data transmission rate of the second communication network based on a total data amount of the data transmitted by the terminal device using the second communication network includes: determining the data transmission rate based on a second formula and the second value.

Wherein said determining said data transmission rate based on a second formula and said second value comprises: determining the data transmission rate based on a second formula and the second value in a case where the terminal device processes a second task using the second communication network.

And under the second task, the total data volume received by the terminal equipment is greater than a second set value, and the total data volume sent by the terminal equipment is less than the second set value. The second task is, for example, audio playing, video downloading, video watching, or other tasks that receive a large amount of data.

Wherein the second formula is: the speed is (E + F)/T2, where the speed is a data transmission rate, the T2 is a duration of the first time period, the E is a total data volume received by the terminal device using the communication network, and the F is a fixed value.

For example, assuming that the duration of the first period is 1min, the second value is 9MB, and F is 0.1MB, the data transmission rate of the second communication network is (9+0.1)/1 is 9.1 MB/min.

Optionally, the determining a data transmission rate of the second communication network based on a total data amount of the data transmitted by the terminal device using the second communication network includes: determining the data transmission rate based on a third formula and the first value.

Wherein said determining said data transmission rate based on said third formula and said first value comprises: determining the data transmission rate based on a third formula and the first value in a case where the terminal device processes a third task using the second communication network.

And under the third task, the total data volume sent by the terminal equipment is greater than a third set value, and the received total data volume is less than the third set value. The third task is, for example, application upload, video upload, audio upload, or other task that transmits a large amount of data.

Wherein the third formula is: the speed is (G + H)/T3, where the speed is a data transmission rate, the T3 is a duration of a first time period, the G is a total data volume sent by the terminal device using a communication network, and the H is a fixed value.

For example, assuming that the duration of the first period is 1min, the first value is 9MB, and H is 0.2MB, then the data transmission rate of the first communication network is (9+0.2)/2 is 9.2 MB/min.

The first set value, the second set value, and the third set value may be the same or different, and are not limited herein.

Optionally, the determining a network transmission quality assessment value of the terminal device based on the data transmission rate includes: and taking the data transmission rate as a network transmission quality evaluation value of the terminal equipment.

It can be seen that, in the embodiment of the present application, the network transmission quality evaluation value of the terminal device is determined based on the data transmission rate, and the requirement condition of the terminal device in terms of data transmission can be accurately evaluated.

if the data transmission rate is less than or equal to a third threshold, changing the judgment threshold of the communication quality evaluation value from the first threshold to a fourth threshold, where the third threshold is less than the fourth threshold, and the fourth threshold is less than the second threshold.

The third threshold and the fourth threshold may be preset.

For example, if the first threshold is 10MB/min, the third threshold is 5MB/min, and the data transfer rate is 4.5MB/min, the first threshold is changed to the fourth threshold of 4 MB/min.

It can be seen that, in the embodiment of the present application, when the network transmission quality assessment value of the terminal device is low, the determination threshold of the network transmission quality assessment value is reduced, which is beneficial to avoiding frequent release of the communication network by the terminal device in the dual connection state.

In an implementation manner of the present application, after releasing the second communication network, the method further includes:

if the transmission power of the terminal device to the first access network device needs to be adjusted, determining a first transmission power based on first information, where the first information includes at least one of: a first application running in the foreground of the terminal device, a first distance between the terminal device and the first access network device, and a first remaining capacity of the terminal device;

The first transmission power is lower than the transmission power of the current terminal equipment to the first access network equipment; or the first transmission power is higher than the transmission power of the current terminal equipment to the first access network equipment.

Optionally, the first information includes the first application, and the determining the first transmission power based on the first information includes: and determining first transmission power based on the first application and a first mapping relation, wherein the first mapping relation is the mapping relation between the application and the transmission power. The first mapping relationship is shown in table 1.

In one implementation, the determining the third value includes: a third value is determined based on a fourth value and a fourth formula, the fourth value being a total amount of data transmitted by the first application over the second communication network within a third time period.

The fourth formula is Total (T5) (S/T4), where Total is an amount of data expected to be sent, T4 is a duration of the third time period, T5 is a duration of the second time period, and S is a Total amount of data transmitted by the first application through the second communication network in the third time period.
