The embodiment of the invention dynamically selects to open and close part of the transmitting link (including a radio frequency front end transmitting device and a transmitting channel in a radio frequency chip, such as an up-conversion module) based on various factors such as the service type of the terminal, the network coverage condition, the residual electric quantity and the like, thereby reducing the power consumption of the radio frequency transmitting link of the terminal and avoiding or reducing the conditions of terminal off-line and the like caused by the reduction of the transmitting power.
Referring to fig. 2, a service transmission method provided in an embodiment of the present invention is applied to a terminal, where the terminal includes at least 2 radio frequency transmission links, and as shown in fig. 2, the method includes:
Here, the embodiment of the present invention may perform statistics on the uplink rate of each service, so as to locally maintain the first corresponding relationship between the service type and the uplink rate. When initiating the connection for establishing the current service, the terminal determines the uplink rate requirement of the current service according to the corresponding relationship between the service type and the uplink rate of the service maintained locally.
If the uplink rate of the currently initiated service is not maintained in the first corresponding relationship, the service can be initiated according to a common service initiation process, and the uplink rate of the service is counted in a service data transmission process to maintain the service type and the uplink rate requirement of the service.
And step 22, when the uplink rate requirement of the currently initiated service belongs to a preset low-speed service, closing part of radio frequency transmission links of the terminal.
Here, a low-speed rate threshold may be predefined on the terminal, and when the uplink rate requirement of the currently initiated service does not exceed the threshold, the uplink rate requirement of the currently initiated service is considered to belong to the preset low-speed service, and at this time, a part of the radio frequency transmission link of the terminal may be closed. Specifically, how many radio frequency transmission links are closed and how many radio frequency transmission links are reserved can be determined according to factors such as the uplink rate requirement of the currently initiated service and the remaining power of the terminal. For example, when the uplink rate requirement is very small, most of the rf transmission links may be turned off, and only one rf transmission link may be reserved, whereas when the uplink rate requirement is relatively large, 2 or more rf transmission links may be reserved.
Through the above steps, the terminal in the embodiment of the present invention may close part of the radio frequency transmission link of the terminal according to the uplink rate requirement of the currently initiated service when the service belongs to the preset low-speed service, for example, close a transmission path inside a radio frequency front end transmitter and/or a radio frequency chip in the part of the radio frequency transmission link, thereby reducing power consumption generated by the radio frequency transmission link.
In the embodiment of the present invention, when part of the radio frequency transmission links is turned off in step 21, specific processing may be further performed according to the current network coverage condition. For example, the terminal may determine whether the current network coverage indicator is better than a preset coverage threshold, where the network coverage indicator may be evaluated by using a received Signal quality parameter, for example, Reference Signal Receiving Power (RSRP), or the like. If the current network coverage index is better than a preset coverage threshold, the current network coverage condition is better, and at the moment, part of radio frequency transmission links can be directly closed. When the current network coverage index is not better than the preset coverage threshold, the network coverage condition is poor, if part of the radio frequency transmission link is directly closed, the terminal is possibly off-line due to the reduction of the transmission power, therefore, the embodiment of the invention firstly improves the transmission power of the single-channel radio frequency transmission link, then closes part of the radio frequency transmission link to avoid the terminal from off-line, and then when the terminal continuously keeps the network on-line state, the transmission power of the single-channel radio frequency transmission link can be gradually reduced according to a preset strategy (for example, adjustment is carried out according to a preset adjustment period and a preset power adjustment step length) to reduce the transmission power to a more appropriate interval, thereby further saving the terminal power consumption.
In the above step 22, it is determined whether the uplink rate requirement of the currently initiated service belongs to the preset high-speed service according to whether the uplink rate requirement of the currently initiated service is not lower than the high-speed rate threshold.
As shown in fig. 3, when the current service belongs to the high-speed service, the terminal may obtain the service quality determined by the network side for the terminal and perform power adjustment of the radio frequency transmission link according to the following steps:
the terminal determines an initial value of the service quality of the service according to a second correspondence between the service type and the service quality maintained locally (S31). The terminal then sends a connection establishment request to the network carrying the initial value of quality of service, which is forwarded by the radio access network to the core network (S32).
The core network carries on the first adjustment to the service quality initial value of the said terminal according to the signing service quality information of the said terminal, obtain the adjustment value of the service quality of the said terminal (S33), and provide the adjustment value of the service quality of the said terminal to the wireless access network (S34), the wireless access network can further adjust the adjustment value of the service quality according to the wireless resource use condition, get the final service quality correction value, and provide the service quality correction value to the core network (S35); the core network feeds back the service quality correction value to the terminal as a final service quality parameter of the terminal (S36).
The terminal receives a qos modification value returned by the network for the qos initial value, where the qos modification value is not generally better than the qos initial value, and the terminal may reduce the configuration of the rf transmission link according to the qos modification value, so that the power consumption of the rf transmission link of the terminal may be reduced (S37).
When the current initiated service is judged to belong to neither the high-speed service nor the low-speed service according to the uplink rate requirement of the service, the connection can be established and the service can be executed according to the common service initiation flow.
In the service data transmission process, the embodiment of the invention can count the uplink rate and the service quality parameters of the service, and update the first corresponding relation and the second corresponding relation maintained locally according to the uplink rate and the service quality parameters obtained through statistics.
Specifically, the updating of the correspondence relationship may refer to fig. 4:
the terminal counts a first uplink rate of the service in each data transmission and a service quality of the service (S41), where the service quality of the service may be a service quality determined by the network side for the terminal, for example, a service quality correction value in the foregoing, and the first uplink rate may be an average value of the uplink rates of the data transmission processes. The terminal determines whether the service exists in the first corresponding relationship, that is, whether the service type of the service and the uplink rate corresponding to the service type are maintained in the first corresponding relationship (S42).
When the service does not exist in the first corresponding relationship, the terminal directly increases the service type of the service and the corresponding first uplink rate thereof in the first corresponding relationship, and increases the service type of the service and the corresponding service quality thereof in the second corresponding relationship (S43);
when the service exists in the first corresponding relationship, the terminal determines whether the first uplink rate matches with the second uplink rate of the service in the corresponding relationship (S44), where matching means that the difference between the two is within a predetermined range;
when the first uplink rate is not matched with the second uplink rate, returning to the step S41, and continuing to perform processing such as statistics of the service uplink rate in the next data transmission process; when the first uplink rate is not matched with the second uplink rate, further judging whether the first uplink rate is greater than the second uplink rate (S45), if so, updating the rate enhancement times of the service, and adding 1 to the rate enhancement times (S46); otherwise, the number of rate reductions of the service is updated, and 1 is added to the number of rate reductions (S47).
Then, the terminal determines whether the ratio of the number of rate enhancements or rate reductions of the service to the counted total number of data transmissions exceeds a predetermined threshold (S48): if not, returning to S41, and continuing to perform the statistics and other processing of the service uplink rate in the next data transmission process; if the first uplink rate and the service quality of the service are exceeded, updating the uplink rate and the service quality parameter corresponding to the service type of the service maintained locally (S48) according to the first uplink rate and the service quality of the service obtained through statistics, that is, updating the uplink rate corresponding to the service type of the service in the first corresponding relationship to the first uplink rate, updating the service quality corresponding to the service type of the service in the second corresponding relationship to the service quality parameter obtained through statistics, and then continuing to perform processing such as statistics of the service uplink rate in the next data transmission process.
The embodiment of the invention can also control the power consumption of the radio frequency transmission link of the terminal according to the residual electric quantity of the terminal. For example, before step 21, the terminal may determine whether the current remaining power is lower than a preset power threshold: and when the current residual electric quantity is lower than a preset threshold, directly closing part of radio frequency transmission links of the terminal so as to avoid shutdown of the terminal due to over-low electric quantity.
It can be seen from the above method that, in the embodiment of the present invention, a part of the radio frequency transmission links is closed under the condition that the service has low requirement on the data uplink rate, so that the radio frequency power consumption can be reduced, and the rate experience of the high-speed service can be ensured.
Correspondingly, an embodiment of the present invention further provides a service transmission method, which is applied to a network side device, and as shown in fig. 5, the method includes:
And 53, the network returns the service quality correction value to the terminal, wherein the service quality correction value is not superior to the service quality initial value.
For example, the core network may perform initial adjustment on the initial value of the service quality of the terminal according to the subscribed service quality information of the terminal to obtain an adjustment value of the service quality of the terminal, and provide the adjustment value of the service quality of the terminal to the radio access network, and the radio access network may further adjust the adjustment value of the service quality according to the usage of radio resources to obtain a final service quality correction value, and provide the service quality correction value to the core network; the core network feeds the service quality correction value back to the terminal as the final service quality parameter of the terminal.
Through the steps, the network side can determine the service quality of the terminal and indicate the service quality to the terminal according to the signed service quality information and/or the wireless resource use condition of the terminal in the service initiating process, so that the terminal can adjust the configuration of the radio frequency transmitting link of the terminal according to the service quality returned by the network, for example, the configuration of the radio frequency transmitting link is reduced, and the power consumption of the radio frequency transmitting link is reduced.
Based on the method, the embodiment of the invention also provides equipment for implementing the method.
