Description

Method and device for regulating and controlling CA (certificate authority) capability level of mobile terminal and mobile terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for regulating and controlling a CA capability level of a mobile terminal, and a mobile terminal.

Background

In order to improve the overall performance of the system, the lte (long Term evolution) system introduces a Carrier Aggregation (CA) technology. By using the carrier aggregation technology, a plurality of continuous or discrete LTE system carriers can be expanded into one carrier capable of meeting the requirement. In a carrier aggregation process, User Equipment (UE) may send and receive data through multiple cells, where the data includes a Primary Cell (PCell) and one or more Secondary cells (scells).

The Deactivation process of the secondary cell may be based on a mac (media Access control) control message or may be based on a Deactivation Timer (Deactivation Timer). If the UE does not receive a Physical Downlink Control Channel (PDCCH) message or service data on a certain secondary cell within a time period specified by the deactivation timer, the UE actively deactivates the corresponding secondary cell. If the value of the deactivation timer of a certain UE is configured to "define", it indicates that the UE is not allowed to actively deactivate a certain secondary cell, in which case the deactivation procedure of the secondary cell can only be triggered by a MAC control message.

In practical applications, the data transmission speed of the UE operating in the CA mode is usually faster than the data transmission speed of the UE operating in the single carrier mode, but there are also situations where the data transmission speed of the UE operating in the CA mode is slower than the data transmission speed of the UE operating in the single carrier mode or the data transmission speed of the UE operating in the CA mode is almost the same as the data transmission speed of the UE operating in the single carrier mode, and the energy consumption of the UE operating in the CA mode is higher than the energy consumption of the UE operating in the single carrier mode. The UE cannot reasonably deactivate the secondary cell by the existing method of deactivating the secondary cell, which results in the decrease of the service performance of the UE and affects the experience of the user.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the notification information access method and the notification information access apparatus is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In the prior art, when establishing a connection, a UE accesses a PCell, and is responsible for rrc (radio resource control) communication with the UE, and when reporting a capability level to a base station, the UE notifies the base station whether the UE supports CA. And when the SCell is in RRC Reconfiguration, adding the SCell through an RRC Connection Reconfiguration message RRC Connection Reconfiguration for providing additional wireless resources.

When an enodeb (evolved Node b) adds an SCell for a UE, the SCell is in a deactivated state by default. Subsequently, the ENodeB can manage the state of the SCell according to the actual situation, so that the wireless resources of the system can be more effectively utilized, and the throughput of the system is improved. For example, the ENodeB may temporarily deactivate a certain SCell of the UE, reduce consumption of radio resources, and may be able to quickly restore the SCell to an activated state when needed by the UE, thereby increasing a data transmission rate. More power is consumed by the UE when the SCell is in the active state. When the SCell is in a deactivated state and does not participate in data transmission, the UE only performs necessary simple measurements on it.

The activation procedure of the SCell is based on the MAC control message, and the deactivation procedure may be based on the MAC control message or based on the deactivation timer.

In a real scenario, since the bandwidths and modulation schemes of PCELL and SCELL in CA mode are determined by the base station, the data transmission rate in single carrier mode may be higher than or equal to the rate in CA mode. At this time, the UE cannot actively deactivate the SCELL by means of deactivating the timer, and the base station determines whether to deactivate the SCELL based on the MAC control message, so that the UE cannot autonomously deactivate the SCELL or automatically turn off the CA, resulting in that the UE continues to operate in the CA mode (higher energy consumption than the single carrier mode), and at this time, the UE cannot enjoy high speed and save energy, and the user experience is poor.

In order to ensure the efficiency of the mobile terminal operating in the CA mode, embodiments of the present invention provide a method and an apparatus for regulating and controlling a CA capability level of the mobile terminal, and the mobile terminal, wherein the mobile terminal in the embodiments of the present invention may be a mobile device such as a mobile phone or a tablet computer that supports the CA mode of LTE. The following detailed description of embodiments of the invention refers to the accompanying drawings.

Example 1

Fig. 1 is a flowchart illustrating a first embodiment of a method for regulating a CA capability level of a mobile terminal according to the present invention. The method can be executed by a mobile terminal, and the method flow shown in the embodiment comprises the following steps:

step S11, when the mobile terminal establishes a connection with the current base station in the single carrier mode, recording the air interface transmission performance in the single carrier mode.

When establishing connection, the mobile terminal initiates registration to the base station and reports the capability level to the base station; after the mobile terminal is connected to LTE (at this time, PCELL is accessed, that is, a single carrier mode), the air interface transmission performance of the terminal in the single carrier mode is recorded. The air interface transmission performance at least comprises one of the following performances: configured modulation and demodulation modes and actual transmission performance. The modulation and demodulation scheme of the mobile terminal is determined by the base station, and specifically, the modulation and demodulation scheme determines the operating bandwidth of the mobile terminal and the size of the modulation data block.

And step S12, when the mobile terminal works in the CA mode, recording the air interface transmission performance in the CA mode.

And the base station sends an RRC connection reconfiguration message, adds the SCell, enables the mobile terminal to work in a CA mode, and records the empty port transmission performance of the mobile terminal in the CA mode. The number of scells accessed by the mobile terminal may be one or more. It can be understood that the air interface transmission performance of the mobile terminal in the CA mode is determined by the PCELL and the SCell that are accessed by the mobile terminal, and the better the air interface transmission performance is, the higher the data transmission speed of the mobile terminal is.

Step S13, the CA capability level of the mobile terminal is adjusted by comparing the air interface transmission performance in the single carrier mode with the air interface transmission performance in the CA mode.

Specifically, how to regulate and control the CA capability level of the mobile terminal is determined by comparing whether the air interface transmission performance in the single carrier mode is better than the air interface transmission performance in the CA mode, and if the comparison result is better, the capability level of the mobile terminal supporting the CA mode is closed. Based on the content included in the air interface transmission performance, whether the air interface transmission performance in the single carrier mode is better than that in the CA mode can be determined by comparing the working bandwidth, the actual transmission performance and the modulation data block in the single carrier mode and the CA mode.

In the method provided by this embodiment, by adjusting and controlling the CA capability level of the mobile terminal, when the air interface transmission performance of the mobile terminal operating in the single carrier mode is better than the air interface transmission performance in the CA mode, the capability level of the mobile terminal supporting the CA mode is automatically closed, so that the mobile terminal operates in the single carrier mode while closing the CA, and the cruising speed and the data transmission speed of the mobile terminal are effectively considered; meanwhile, the mode is to automatically regulate and control the CA capability level, so that a CA switch is not required to be added on a UI (user operation interface) of the mobile terminal, the user does not need to participate in operation, the intelligent degree of the mobile terminal is improved, and the mode for automatically regulating and controlling the CA capability level can reasonably prolong the cruising ability of the mobile terminal on the premise of ensuring the data transmission speed, so that the user experience is improved.

Considering that there is a communication environment change after the capability level of the mobile terminal supporting the CA mode is turned off, the embodiment further provides a step of automatically turning on the capability level of the mobile terminal supporting the CA mode, which is specifically as follows:

(1) and when the capability level of the mobile terminal for supporting the CA mode is in an off state, periodically monitoring the current air interface transmission performance of the mobile terminal.

(2) And judging whether the current air interface transmission performance is lower than the recorded air interface transmission performance under the CA mode. Wherein, the recorded air interface transmission performance in the CA mode is the air interface transmission performance in the CA mode in step S12.

(3) If so, starting the capability level of the mobile terminal supporting the CA mode, and updating the recorded air interface transmission performance in the CA mode.

The above manner of automatically starting the capability level of the CA mode can restart the capability level of the CA mode when the current transmission performance of the air interface is lower than the recorded transmission performance of the air interface in the CA mode, so that the mobile terminal obtains a better data transmission speed, and further, the user experience is improved.

Example 2

Fig. 2 is a schematic flow chart of a second embodiment of a method for adjusting and controlling a CA capability level of a mobile terminal according to the present invention, where the adjusting and controlling method of this embodiment mainly takes as an example that a working bandwidth of the mobile terminal determines whether an air interface transmission performance in a single carrier mode is better than an air interface transmission performance in a CA mode, and a method flow shown in this embodiment includes the following steps:

in step S21, the mobile terminal is powered on.

In step S22, the mobile terminal sets a special NV and sets the value of the NV to 0. That is, NV ca _ disable is 0.

Whether the mobile terminal has CA capability is identified by the NV as described above, and the mobile terminal is identified as supporting the CA mode at this time, that is, the capability level of the CA mode is in an open state. Taking a high-pass platform as an example, the NV is placed under the path NV/item _ files/modem/lte/common.

Step S23, the mobile terminal establishes a connection with the current base station in a single carrier mode, and records the air interface transmission performance in the single carrier mode.

The air interface transmission performance at least comprises one of the following performances: configured modulation and demodulation modes and actual transmission performance. The modulation and demodulation scheme of the mobile terminal is determined by the base station, and specifically, the modulation and demodulation scheme determines the operating bandwidth of the mobile terminal and the size of the modulation data block.

And step S24, the mobile terminal works in the CA mode and records the air interface transmission performance in the CA mode.

The air interface transmission performance of the mobile terminal in the CA mode is determined by the PCELL and the SCell which are accessed by the mobile terminal.

Step S25, whether the working bandwidth of the mobile terminal in the single carrier mode is greater than or equal to the working bandwidth in the CA mode, if so, step S26 is executed, otherwise, the operation is terminated.

The working bandwidth is specifically the number of RBs (Resource Block) of the mobile terminal in the current mode, for example, the number of RBs is 100, and corresponds to 20MHZ of downlink. Comparing whether the number of RBs of the mobile terminal in the single carrier mode (the number of RBs of the PCELL) is greater than or equal to the number of RBs in the CA mode (the sum of the number of RBs of the PCELL and the number of RBs of the SCell) is not the same because the bandwidth of the mobile terminal is configured by the base station. When the number of RBs of the mobile terminal in the single carrier mode is greater than or equal to the number of RBs in the CA mode, it is considered that the single carrier mode can provide a better data transmission speed, and thus active shutdown of the CA mode is required.

In step S26, the value of NV is set to 1. That is, NV ca _ disable is 1.

Setting the NV to 1, the capability level of the mobile terminal that supports the CA mode is turned off, i.e. the mobile terminal is identified as not supporting the CA mode, and therefore, the base station will not be triggered to reconfigure the SCell, and the mobile terminal will not perform operations such as measurement on the originally configured SCell. The CA is now in the off state.

It should be noted here that the above CA turning off and SCell deactivation are different: closing the CA, identifying that the mobile terminal does not support the CA mode, and the base station cannot configure the SCell for the mobile terminal, and the mobile terminal does not need to start or maintain the operation of the SCell; the SCell is deactivated, and the ENodeB can also dynamically activate and deactivate the SCell through a MAC control message.

The results of the mobile terminal in the single carrier mode and the CA mode shown in table 1 are compared, and the following test results are obtained by connecting the mobile terminal to the CMW500 wireless communication comprehensive tester through the radio frequency head:

TABLE 1

Wherein, PCell is B1, SCell is B3; the single carrier mode and the TX POWER (the transmitting POWER of the mobile terminal) of the CA mode are the same and are both 23 dbm; the modulation modes are the same and are all 64 QAM; the bandwidths are 20M and 10M +10M, respectively.

The download speeds obtained under the above test conditions were 149mb/s and 156mb/s, respectively, while the operating current of the mobile terminal in the single carrier mode was reduced by 78mA compared to that in the CA mode.

In the above test conditions, the bandwidths of the two are equal, and the determination condition in step S25 is satisfied: the operating bandwidth of the mobile terminal in the single carrier mode is equal to the operating bandwidth in the CA mode. At this time, step S26 is executed to set the value of NV to 1, i.e., NV ca _ disable to 1. Therefore, under the condition of ensuring that the downloading speed of the mobile terminal is basically unchanged, the energy consumption of the mobile terminal is reduced. Meanwhile, it can be understood that, in the case that the bandwidth of the PCell in the single carrier mode is greater than the sum of the bandwidths of the PCell and the SCell in the CA mode, the mobile terminal may obtain a greater download speed in the single carrier mode.

(1) and when the CA mode is in a closed state, periodically monitoring the current air interface transmission performance of the mobile terminal.

(2) And judging whether the current air interface transmission performance is lower than the recorded air interface transmission performance under the CA mode. Specifically, in this embodiment, it is determined whether the operating bandwidth of the mobile terminal in the single carrier mode is smaller than the operating bandwidth in the recorded CA mode, where the operating bandwidth in the recorded CA mode is the operating bandwidth in the CA mode in step S24

(3) If so, starting the capability level of the mobile terminal supporting the CA mode, and updating the recorded air interface transmission performance in the CA mode. Specifically, in the present embodiment, the operating bandwidth in the CA mode is updated.

In the method provided by this embodiment, by closing the capability level of the mobile terminal supporting the CA mode, when the working bandwidth of the mobile terminal in the single carrier mode is greater than or equal to the working bandwidth in the CA mode, the mobile terminal is automatically identified as not having the CA capability, so that the mobile terminal closes the CA and operates in the single carrier mode, thereby effectively taking into account the cruising and data transmission speeds of the mobile terminal; meanwhile, the mode is to automatically regulate and control the CA capability level, so that a CA switch is not required to be added on a UI of the mobile terminal, the user does not need to participate in operation, the intelligent degree of the mobile terminal is improved, and the mode for automatically regulating and controlling the CA capability level can reasonably prolong the cruising ability of the mobile terminal on the premise of ensuring the data transmission speed, so that the user experience degree is improved.

Example 3

Fig. 3 is a schematic flowchart of a third embodiment of a method for adjusting and controlling a CA capability level of a mobile terminal according to the present invention, where the adjusting and controlling method of this embodiment mainly takes as an example that an actual transmission performance of the mobile terminal determines whether an air interface transmission performance in a single carrier mode is better than an air interface transmission performance in a CA mode, and a method flow shown in this embodiment includes the following steps:

in step S31, the mobile terminal is powered on.

In step S32, the mobile terminal sets a special NV and sets the value of the NV to 0. That is, NV ca _ disable is 0.

Whether the mobile terminal has CA capability is identified by the NV as described above, and the mobile terminal is identified as supporting the CA mode at this time, that is, the capability level of the CA mode is in an open state.

Step S33, the mobile terminal establishes a connection with the current base station in a single carrier mode, and records the air interface transmission performance in the single carrier mode.

And step S34, the mobile terminal works in the CA mode and records the air interface transmission performance in the CA mode.

The air interface transmission performance of the mobile terminal in the CA mode is determined by the PCELL (primary cell) and the SCell (secondary cell) accessed by the mobile terminal.

Step S35, the mobile terminal determines whether the difference between the actual transmission performance of the primary cell in the single carrier mode and the actual transmission performance of the secondary cell in the CA mode is greater than a set threshold, if so, performs step S36, otherwise, terminates.

When the CA mode is a downlink CA mode, the working bandwidth is a downlink working bandwidth, the actual transmission performance is downlink actual transmission performance, and the modulation data block is a downlink modulation data block. Specifically, the actual transmission performance includes a received Signal strength (RSRP) and a Signal-to-NOISE RATIO (SNR), which represent the strength and quality of the Signal transmitted by the base station.

When the difference between the received signal strength of the main cell in the single carrier mode and the received signal strength of the auxiliary cell in the CA mode is larger than a set strength threshold value; or when the difference between the signal-to-noise ratio of the primary cell and the signal-to-noise ratio of the secondary cell is greater than the set signal-to-noise ratio threshold, determining that the difference between the actual transmission performance of the primary cell and the actual transmission performance of the secondary cell is greater than the set threshold. When one of the two conditions is satisfied, it can be determined that the difference between the actual transmission performance of the primary cell and the actual transmission performance of the secondary cell is greater than a set threshold.

The set strength threshold and the set signal-to-noise ratio threshold are selected according to the experience values of the received signal strength and the signal-to-noise ratio difference of the main cell and the auxiliary cell, when the strength threshold and the signal-to-noise ratio threshold are larger than the threshold, the addition speed of the auxiliary cell is different from or equal to the download speed provided by the main cell in a single carrier mode, and at the moment, the efficiency of the mobile terminal working in the single carrier mode is higher. It is empirically preferred that the intensity threshold be 15 and the signal-to-noise threshold be 15.

In step S36, the value of NV is set to 1. That is, NV ca _ disable is 1.

In the method provided by this embodiment, by closing the capability level of the mobile terminal in supporting the CA mode, when the difference between the actual transmission performance of the primary cell when the mobile terminal operates in the single carrier mode and the actual transmission performance of the secondary cell when the mobile terminal operates in the CA mode is greater than the set threshold, the mobile terminal is automatically identified as not having the CA capability, so that the mobile terminal operates in the single carrier mode while closing the CA, and the cruising speed and the data transmission speed of the mobile terminal are effectively considered; meanwhile, the mode is to automatically regulate and control the CA capability level, so that a CA switch is not required to be added on a UI of the mobile terminal, the user does not need to participate in operation, the intelligent degree of the mobile terminal is improved, and the mode for automatically regulating and controlling the CA capability level can reasonably prolong the cruising ability of the mobile terminal on the premise of ensuring the data transmission speed, so that the user experience degree is improved.

Example 4

Fig. 4 is a schematic flowchart of a fourth embodiment of a method for adjusting and controlling a CA capability level of a mobile terminal according to the present invention, where the adjusting and controlling method of this embodiment mainly uses an example of modulating a data block to determine whether an air interface transmission performance in a single carrier mode is better than an air interface transmission performance in a CA mode, and a method flow shown in this embodiment includes the following steps:

in step S41, the mobile terminal is powered on.

In step S42, the mobile terminal sets a special NV and sets the value of the NV to 0. That is, NV ca _ disable is 0.

And identifying whether the mobile terminal has the CA capability or not through the NV, wherein the mobile terminal is identified to support the CA mode, namely the CA is in an open state.

Step S43, the mobile terminal establishes a connection with the current base station in the single carrier mode, and records the air interface transmission performance in the single carrier mode.

And step S44, the mobile terminal works in the CA mode and records the air interface transmission performance in the CA mode.

Step S45, the mobile terminal determines whether the modulated data block in the single carrier mode is larger than the modulated data block in the CA mode, if so, executes step S46, otherwise, terminates.

Since the throughput of the uplink and downlink rates of LTE depends on the TBS selected by the MAC layer scheduling, the Size of the modulation data Block (TBSI) represents the throughput, and when the modulation data Block in the single carrier mode is larger than the modulation data Block in the CA mode, the mobile terminal operates more efficiently in the single carrier mode.

In step S46, the value of NV is set to 1. That is, NV ca _ disable is 1.

In the method provided by the embodiment, by closing the capability level of the mobile terminal supporting the CA mode, when the modulation data block of the mobile terminal working in the single carrier mode is larger than the modulation data block working in the CA mode, the mobile terminal is automatically identified as not having the CA capability, so that the mobile terminal closes the CA and works in the single carrier mode, and the cruising and data transmission speed of the mobile terminal are effectively considered; meanwhile, the mode is to automatically regulate and control the CA capability level, so that a CA switch is not required to be added on a UI of the mobile terminal, the user does not need to participate in operation, the intelligent degree of the mobile terminal is improved, and the mode for automatically regulating and controlling the CA capability level can reasonably prolong the cruising ability of the mobile terminal on the premise of ensuring the data transmission speed, so that the user experience degree is improved.

Step S55, whether the operating bandwidth of the mobile terminal in the single carrier mode is greater than or equal to the operating bandwidth in the CA mode, if not, step S56 is executed, and if so, step S59 is executed.

The mobile terminal works in a single carrier mode, wherein a PCell working bandwidth RB is RB1, a PCell working bandwidth RB is RB2 and an SCell working bandwidth RB is RB 3; whether RB1> RB2+ RB3 or RB1 ═ RB2+ RB3 holds is judged, and if yes, step S59 is executed, and if not, step S56 is executed.

Step S56, whether the difference between the received signal strength of the primary cell in the single carrier mode and the received signal strength of the secondary cell in the CA mode of the mobile terminal is greater than the strength threshold, if not, step S57 is executed, and if so, step S59 is executed.

The above determination 15 is an empirically selected intensity threshold.

Step S57, whether the difference between the snr of the primary cell in the single carrier mode and the snr of the secondary cell in the CA mode is greater than the snr threshold is determined, if not, step S58 is executed, and if yes, step S59 is executed.

The signal-to-noise ratio of the PCell of the mobile terminal working in the single carrier mode is SNR1, and the signal-to-noise ratio of the SCell in the CA mode is SNR 2; it is determined whether | SNR1-SNR2| >15 is established, and if so, step S59 is performed, and if not, step S58 is performed. In the above decision 15 is an empirically selected signal-to-noise threshold.

Step S58, the mobile terminal determines whether the modulated data block in the single carrier mode is larger than the modulated data block in the CA mode, if so, executes step S59, otherwise, terminates.

The modulation data block of the PCell of the mobile terminal working in the single carrier mode is TBSI1, and the modulation data block of the SCell in the CA mode is TBSI 2; and judging whether TBSI1> TBSI2 is established, if so, executing step S59, and if not, terminating, and continuing to work in the CA mode by the mobile terminal.

In step S59, the value of NV is set to 1. That is, NV ca _ disable is 1.
