This application is a divisional application of the Chinese invention patent application 201310374128.X filed on August 23, 2013 with the title of "a method and device for data transmission".

technical field

The invention relates to the field of mobile communication, in particular to a data transmission method and device.

Background technique

With the development of mobile communication technology, the mobile terminal has evolved from the original single call function to voice, data, image, music and multimedia. The current mobile terminals can basically be divided into two types: one is a traditional mobile phone (feature phone); the other is a smart phone (smart phone). Smartphones have the basic functions of traditional mobile phones, and have the following characteristics: open operating system, scalability of hardware and software, and support for secondary development by third parties. Compared with traditional mobile phones, smart phones are more and more favored by people because of their powerful functions and convenient operation.

However, as a portable and mobile terminal, a smart phone completely relies on a battery for power supply. As the functions of the smart phone become more and more powerful, its power consumption is also increasing. Therefore, the use time and standby time of smart phones must be improved. For this problem, there are two solutions: one is to equip a mobile phone battery with larger capacity; the other is to improve the system design and adopt advanced technology to reduce the power loss of the mobile phone.

At this stage, the batteries equipped with mobile phones are mainly lithium-ion batteries. Although the energy density of lithium-ion batteries has increased by nearly 30% compared with the past, it still cannot meet the development needs of smart phones. As far as the currently used lithium-ion battery materials are concerned, there is only about 20% room for improvement in energy density. Another type of fuel cell is widely regarded by the industry as the development trend of mobile phone batteries in the future. It can enable smartphones to have a talk time of more than 13 hours and a standby time of up to one month. However, this battery technology is still immature and far from commercial use. For a period of time. At the same time, the general trend of increasing the battery capacity of mobile phones will increase the cost of the whole machine.

Therefore, starting from the overall design of the smart phone, designing a solution to reduce power consumption, thereby prolonging the use time and standby time of the smart phone as much as possible is a relatively feasible and low-cost solution for reducing the power consumption of the mobile phone.

Generally, the three modules with large power consumption in smartphones are:

1) application processor;

2) LCD screen;

3) RF module.

At present, when a user using a smart phone is not operating the mobile terminal, the application processor and the LCD screen will sleep, but the radio frequency module is still turned on, causing the mobile terminal to consume a lot of power. Therefore, reducing the power consumption of the radio frequency module has become an important means to reduce the power consumption of smart phones.

A dual-mode smart phone refers to a smart phone that provides data transmission of two communication systems at the same time. Compared with single-mode smartphones, dual-mode smartphones may need to provide two channels of data transmission at the same time, and consume more power. Therefore, how to reduce the power consumption of the RF module of dual-mode smartphones, and then reduce the power consumption of smartphones has become Urgent problems.

detailed description

Embodiments of the present invention provide a data transmission method and device. In the method provided by the embodiment of the present invention, when it is determined that the upper-layer application needs to transmit data, at least one radio frequency module in the continuous on state is determined to be the radio frequency module for data transmission, and data transmission is performed for the upper-layer application. By selecting the radio frequency modules in the continuously on state for data transmission, it is not necessary to switch the radio frequency modules in the discontinuously on state to the continuous on state, thereby reducing the overall power consumption of all radio frequency modules of the mobile terminal.

It should be noted that although the problem of power consumption of smart phones is relatively prominent at present, the method of the embodiment of the present invention can reduce the power consumption of the dual-mode smart phone, but the method of the embodiment of the invention is not limited to the dual-mode smart phone, it is applicable to Various dual-mode or multi-mode mobile terminals including multiple radio frequency modules can effectively reduce the power consumption of such mobile terminals.

Below, the implementation conditions of the present invention are limited:

Condition 1. The power consumption of any radio frequency module during data transmission is greater than the power consumption of the radio frequency module when it is continuously turned on but not performing data transmission;

Condition 2. Although each RF module corresponds to a different communication link, the power consumption of each RF module is basically equal when it is in the continuous open state and no data transmission is performed; and, when the RF module performs data transmission, and each RF module When the data transmission rates provided by the corresponding communication links are equal, the power consumption of each radio frequency module is basically equal.

The format of the communication link corresponding to the radio frequency module in the embodiment of the present invention includes but is not limited to: Global System of Mobile Communication (Global System of Mobile communication, GSM), Code Division Multiple Access (Code Division Multiple Access, CDMA) IS-95, Code Division Multiple Access (CDMA) 2000, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Duplexing-Long Term Evolution (TDD LTE), Frequency Division Duplexing-Long Term Evolution (FDD LTE), Long Term Evolution-Advanced (Long Term Evolution-Advanced, LTE-advanced), Personal Handy-phone System (PHS), etc.

FIG. 1 is a schematic diagram of a data transmission method process provided by an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

S101: When it is determined that the upper layer application needs to transmit data, determine the working status of multiple radio frequency modules;

S102: When there are radio frequency modules in the continuous on state among the plurality of radio frequency modules, use at least one radio frequency module in the continuous on state as the radio frequency module for data transmission;

S103: Perform data transmission for the upper layer application through the radio frequency module for data transmission.

In the existing mobile terminal solution, after the mobile terminal is turned on, each radio frequency module of the mobile terminal is continuously turned on. When the mobile terminal is in standby and no data is sent or received, the radio frequency module is still continuously turned on, and the continuous turning on of the radio frequency module causes a large power consumption. consume. In the embodiment of the present invention, after the mobile terminal is turned on, the working state of the radio frequency module includes: a continuous on state and a discontinuous on state. When the radio frequency module is in the continuous on state, it can send and receive data and needs to consume power; when the radio frequency module is in the discontinuous on state, the radio frequency module is turned off intermittently to reduce the power consumption of the radio frequency module, and in the discontinuous on state, When the radio frequency module is turned off, the radio frequency module is turned on, so that the mobile terminal can perform signaling interaction with the network side. During specific implementation, the radio frequency module and the power supply module of the mobile terminal can be connected and disconnected through a hardware or software switch, and the radio frequency module can be turned on and off respectively.

In the embodiment of the present invention, the radio frequency module enters into the discontinuous open state through a certain trigger mechanism. For example, when the time interval from the last data transmission is not less than the preset idle time, the radio frequency module enters the discontinuous open state, and the radio frequency module is turned on during the interval when the radio frequency module is closed, so that the mobile terminal can perform signaling interaction with the network side . When it is determined that data transmission is required according to the signaling received from the network side, the radio frequency module exits the discontinuous on state and enters the continuous on state.

In the embodiment of the present invention, the mobile terminal has multiple radio frequency modules, and each radio frequency module corresponds to a communication link. When it is determined that the upper layer application needs to transmit data, first determine the working status of each radio frequency module; When the radio frequency modules are continuously turned on, at least one radio frequency module in the continuous turned on state is used as a radio frequency module for data transmission, and data transmission is performed for the upper layer application through the determined radio frequency module for data transmission.

In the embodiment of the present invention, upper-layer applications may include, but are not limited to: web browsing, data download, WeChat, real-time video playback, real-time data interaction with the network side initiated by instant messaging software, etc.

In the embodiment of the present invention, when it is determined that the upper-layer application needs to transmit data, the radio frequency module in the continuous open state is selected for data transmission, so as to avoid switching the radio frequency module in the discontinuous open state to the continuous open state, thereby reducing the frequency of each radio frequency of the mobile terminal. The overall power consumption of the module.

Preferably, at least one radio frequency module in a continuous open state is used as a radio frequency module for data transmission, including:

Determine the radio frequency module that matches the data transmission rate required by the upper layer application to transmit data among the radio frequency modules that are continuously turned on;

Select a radio frequency module from the matching radio frequency modules as the radio frequency module for data transmission.

In this preferred solution, when there are multiple radio frequency modules in the continuous open state, first determine the radio frequency module in the continuous open state that matches the data transmission rate required by the upper layer application to transmit data, if the matching radio frequency module If there are more than one radio frequency module, select one radio frequency module as the radio frequency module for data transmission. In this way, large power consumption caused by selecting multiple radio frequency modules for data transmission at the same time is avoided.

A special case is that there is only one radio frequency module in the continuous on state, and the radio frequency module matches the data transmission rate required by the upper layer application to transmit data, then the radio frequency module is the radio frequency module for data transmission.

Another special case is that there are multiple radio frequency modules that are continuously turned on, but there is only one radio frequency module that matches the data transmission rate required by the upper layer application to transmit data, then this radio frequency module is determined to be the radio frequency module for data transmission .

In this preferred solution, there are many ways to determine that the radio frequency module matches the data transmission rate required by the upper layer application to transmit data. For example, if the data transmission rate provided by the communication link corresponding to the radio frequency module is not less than the data transmission rate required by the upper layer application to transmit data, it is determined that the radio frequency module matches the data transmission rate required by the upper layer application to transmit data.

Alternatively, if the data transmission rate provided by the communication link corresponding to the radio frequency module is not less than the product of the data transmission rate required by the upper-layer application for data transmission and the preset rate matching factor, then determine the data transmission rate between the radio frequency module and the upper-layer application. The required data transmission rate is matched, wherein the preset rate matching factor is greater than 0 and not greater than 1.

During specific implementation, the preset rate matching factor may be determined according to the service type corresponding to the upper layer application, and/or the quality of the communication link determined by the mobile terminal and other factors. For example: when the service type corresponding to the upper layer application is a service with high real-time requirements, such as online video, IP voice, etc., the preset rate matching factor can be set to a number close to 1 or even equal to 1, such as: 0.95 Wait. Another example: if the mobile terminal determines that the quality of the communication link is poor, because the data transmission capability that the communication link itself can provide becomes lower due to the poor quality of the communication link, the preset rate matching factor can be set For a smaller number, such as: 0.5 and so on.

In a preferred manner, the preset rate matching factor can be determined according to the following formula [1]:

Rate_ratio=a*Service_type_index + (1-a)* link_quality_index……….[1]

In Formula 1, Rate_ratio is a preset rate matching factor; a is a weight factor, and a is a number greater than 0 and less than or equal to 1; Service_type_index is a service type index, which is a number greater than 0 and less than or equal to 1, which indicates that the upper layer application corresponds to The data transmission rate level required by the service type; link_quality_index is the link quality index, which is a number greater than 0 and less than or equal to 1, which indicates the data transmission rate capability that different link qualities can provide.

For Service_type_index, the service type index can be assigned to different service types according to the following methods, for example: the service type index value of IP voice service is 1, the service type index value of online video service is 0.95, and the service type index value of data download is 0.5 1. The service type index value of the real-time data interaction with the network side initiated by the instant messaging software is 0.9, etc. Alternatively, it can also be defined according to the division of service types in the 3GPP protocol - Streaming (streaming service), Conversational (conversational service), Interactive (interactive service), Background (background service), for example, conversational service The service type index value of the service type is 1, the service type index value of the streaming service is 0.9, the service type index value of the interactive service is 0.8, the service type index value of the background service is 0.5, and so on. The index values of the above service types are only examples, and should not be regarded as a limitation to this preferred solution.

The link_quality_index can be set according to the quality of the downlink detected by the mobile terminal (such as the downlink signal-to-interference ratio (Signal to Interference Ratio, SIR)), the reception level of the downlink signal received by the mobile terminal, and the like. For example, when determined according to the current channel SIR, if the quality of the downlink is good (that is, the SIR is relatively large, the relevant threshold value can be set during specific implementation), set link_quality_index to a larger value, and when the quality of the downlink is relatively high When poor, set link_quality_index to a smaller value.

The above method of determining whether the data transmission rate required by the radio frequency module to transmit data to the upper-layer application matches is applicable to all solutions in the embodiments of the present invention that need to determine whether the data transmission rate required by the radio frequency module to transmit data to the upper-layer application matches.

Preferably, using at least one radio frequency module in a continuous open state as a radio frequency module for data transmission, further comprising:

When there is no radio frequency module that is continuously turned on that matches the data transmission rate required by the upper-layer application to transmit data, the corresponding The data transmission rate that can be provided by the communication link determines that multiple radio frequency modules that are continuously turned on are the radio frequency modules for data transmission.

When there is no radio frequency module that is continuously turned on that matches the data transmission rate required by the upper layer application to transmit data, there are many ways to determine the radio frequency module for data transmission. One of the implementation methods is:

First, determine the data transmission rate required by the upper layer application to transmit data, and the data transmission rate that can be provided by the communication link corresponding to each radio frequency module that is continuously turned on;

If the data transmission rate required by the upper layer application to transmit data is not less than the sum of the data transmission rates that can be provided by the communication links corresponding to all radio frequency modules that are continuously on, then determine that all radio frequency modules that are continuously on are the ones for data transmission The radio frequency module ensures the data transmission of the upper layer application;

If the data transmission rate required by the upper-layer application to transmit data is less than the sum of the data transmission rates that can be provided by the communication links corresponding to all radio frequency modules that are in the continuous on state, then determine multiple radio frequency modules that are in the continuous on state as the data transmission A radio frequency module, so that the sum of the data transmission rates that can be provided by the communication links corresponding to the plurality of radio frequency modules is not less than the data transmission rate required by the upper layer application to transmit data, and the number of radio frequency modules for data transmission is the least, so that, It can not only ensure the data transmission of the upper layer application, but also use the least radio frequency module, so as to reduce the overall power consumption of each radio frequency module of the mobile terminal.

Preferably, after determining the working status of each radio frequency module, before using the determined radio frequency module for data transmission to perform data transmission for the upper layer application, the method provided by the embodiment of the present invention further includes:

If all radio frequency modules are in the discontinuous open state, determine the radio frequency module that matches the data transmission rate required by the upper layer application to transmit data;

Select the radio frequency module that is turned off with the shortest off period as the radio frequency module for data transmission from the matched radio frequency modules, and switch the selected radio frequency module to a continuous on state.

In this preferred solution, if all the radio frequency modules are in the discontinuous on state, one or more radio frequency modules need to be switched to the continuous on state for data transmission. First, determine the radio frequency module that matches the data transmission rate required by the upper layer application to transmit data, and determine whether the radio frequency module matches the data transmission rate required by the upper layer application to transmit data. The method has been described above and will not be repeated here. Select the radio frequency module that is closed with the shortest off period from the matching radio frequency modules as the radio frequency module for data transmission, and switch the selected radio frequency module to the continuous open state, which not only ensures the data transmission of the upper layer application, but also, if different The off periods of the radio frequency modules are different. Since the power consumption of the radio frequency modules with a long off period is relatively small, the radio frequency module with the shortest off period is selected as the radio frequency module for data transmission, thereby reducing the overall power consumption of each radio frequency module of the mobile terminal.

In addition, from the matching radio frequency modules, the radio frequency module whose corresponding communication link can provide the maximum data transmission rate can also be selected as the radio frequency module for data transmission, so as to reduce the data transmission time of the radio frequency module and make it return to the non-operating network as soon as possible. This method can also reduce the overall power consumption of each radio frequency module of the mobile terminal.

Preferably, after determining the working status of each radio frequency module, before using the determined radio frequency module for data transmission to perform data transmission for the upper layer application, the method provided by the embodiment of the present invention further includes:

When all radio frequency modules are in discontinuous open state, and there is no radio frequency module that matches the data transmission rate required by the upper layer application to transmit data, multiple methods can be used to determine the radio frequency module for data transmission, one of which is yes:

First, determine the data transmission rate required by the upper layer application to transmit data and the sum of the data transmission rates that can be provided by the communication links corresponding to all radio frequency modules;

If the former is not less than the latter, all radio frequency modules are determined to be radio frequency modules for data transmission, so as to ensure the data transmission of upper layer applications to the greatest extent;

If the former is less than the latter, determine that multiple radio frequency modules are radio frequency modules for data transmission, so that the sum of the data transmission rates that can be provided by the communication links corresponding to the multiple radio frequency modules is not less than that required by the upper layer application to transmit data The data transmission rate is high, and the number of radio frequency modules for data transmission is the least. In this way, the data transmission of the upper layer application can be guaranteed, and the minimum number of radio frequency modules can be used to reduce the overall power consumption of each radio frequency module of the mobile terminal.
