Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more specifically, to a communication method and an electronic device of a communication terminal. Background Art

[0002] Usually, the service data of applications installed on communication terminals comes from application processors. In this case, because the application processor needs to process many programs in the foreground and background at the same time, the application processor will introduce a certain delay. In addition, when the service data of the application processor comes from the communication processor, the communication processor communicates with the base station through the radio frequency air interface according to the 3GPP protocol, so the communication processor will also cause delays in the reception and transmission of service data.

[0003] Therefore, there is a need for a technology that reduces the delay in receiving and / or sending service data of an application installed on a communication terminal. Summary of the invention

[0004] This Summary is provided to introduce in simplified form a selection of concepts that are further described below in the Detailed Description. This Summary is not intended to identify key features and / or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0005] According to some example embodiments, a communication method of a communication terminal includes: in response to the communication terminal entering a first mode, detecting the state of the radio resource control (RRC) of the communication terminal; in response to the communication terminal being in an RRC idle state, controlling the communication terminal to enter and remain in an RRC connected state, and prohibiting the communication terminal from entering a discontinuous reception (DRX) state; in response to the communication terminal being in an RRC connected state, controlling the communication terminal to remain in the RRC connected state; and receiving or sending business data of an application installed on the communication terminal in the RRC connected state.

[0006] According to some example embodiments, a communication terminal includes: a memory storing one or more instructions; and a processor configured to execute the one or more instructions to: detect the state of the radio resource control (RRC) of the communication terminal based on the communication terminal entering a first mode; control the communication terminal to enter and remain in an RRC connected state, and prohibit the communication terminal from entering a discontinuous reception (DRX) state based on the communication terminal being in an RRC connected state; control the communication terminal to remain in the RRC connected state based on the communication terminal being in an RRC connected state; and receive or send business data of an application installed on the communication terminal in the RRC connected state.

[0007] The processor may also be configured to execute the one or more instructions to: in response to the communication terminal being in an RRC connected state and not in a DRX state, control the communication terminal to remain in the RRC connected state and prohibit the communication terminal from entering the DRX state; in response to the communication terminal being in the DRX state, control the communication terminal to remain in the DRX state.

[0008] The processor may also be configured to execute the one or more instructions to: in response to the communication terminal being in the RRC idle state, control the communication terminal to operate on the highest priority network standard that the communication terminal can actually support, control the communication terminal to enter and remain in the RRC connected state, and prohibit the communication terminal from entering the DRX state.

[0009] The processor can also be configured to execute the one or more instructions to: obtain the first network standard with the highest priority that can be supported by the user identification module SIM card of the communication terminal; obtain the second network standard with the highest priority that can be supported by the communication terminal; determine the network standard with a lower priority between the first network standard and the second network standard; determine whether the network standard currently running on the communication terminal is the same as the third network standard; based on the fact that the network standard currently running on the communication terminal is different from the third network standard, obtain the fourth network standard with the highest priority that can be supported in the current wireless network environment; determine the network standard with a lower priority between the third network standard and the fourth network standard as the network standard with the highest priority that can actually be supported by the communication terminal; and operate the communication terminal on the network standard with the highest priority that can actually be supported by the communication terminal.

[0010] The step of controlling the communication terminal to remain in the RRC connected state may include: when the communication terminal is in the RRC connected state and the communication terminal has not sent and received service data within a reference time, periodically sending an uplink scheduling request without using an application processor of the communication terminal, and when the network schedules the communication terminal through a physical downlink control channel and allocates uplink physical shared channel uplink resources, if the communication terminal actually has no uplink service data to be sent, sending a dummy data packet filled with all zeros to the network through the uplink physical shared channel; or in response to the network configuring a measurement control message for the service volume for the communication terminal and the service volume to be sent by the communication terminal uplink is zero, reporting a non-zero cache status report so that the RRC connected state is not released by the network; or in response to the RRC connected state being released by the network, controlling the communication terminal to enter and remain in the RRC connected state again, and prohibiting the communication terminal from entering the DRX state.

[0011] According to some example embodiments, a communication method of a communication terminal includes: in response to the communication terminal entering a predetermined mode, detecting the state of a radio resource control (RRC) of the communication terminal; in response to the communication terminal being in an RRC idle state, causing the communication terminal to enter and remain in an RRC connected state, and prohibiting the communication terminal from entering a discontinuous reception (DRX) state; in response to the communication terminal being in an RRC connected state, causing the communication terminal to remain in the RRC connected state; and receiving and / or sending business data of an application installed on the communication terminal in the RRC connected state.

[0012] The step of keeping the communication terminal in the RRC connected state in response to the communication terminal being in the RRC connected state may include: keeping the communication terminal in the RRC connected state and prohibiting the communication terminal from entering the DRX state in response to the communication terminal being in the RRC connected state and not in the DRX state, and keeping the communication terminal in the DRX state in response to the communication terminal being in the DRX state.

[0013] The communication method may further include: in response to the communication terminal being in the RRC idle state, causing the communication terminal to reside on the highest priority network standard that the communication terminal can actually support, causing the communication terminal to enter and remain in the RRC connected state, and prohibiting the communication terminal from entering the DRX state.

[0014] The step of making the communication terminal reside on the highest priority network standard that the communication terminal can actually support may include: obtaining the first network standard with the highest priority that the SIM card of the communication terminal can support; obtaining the second network standard with the highest priority that the communication terminal can support; determining the network standard with a lower priority between the first network standard and the second network standard as the third network standard that is the highest priority network standard that the communication terminal can actually support; determining whether the network standard currently resided by the communication terminal is the same as the third network standard, and in response to the network standard currently resided by the communication terminal being different from the third network standard, obtaining the fourth network standard with the highest priority that can be supported in the current wireless network environment, determining the network standard with a lower priority between the third network standard and the fourth network standard as the network standard with the highest priority that the communication terminal can actually support, and making the communication terminal reside on the network standard with the highest priority that the communication terminal can actually support.

[0015] The priority of the network standard may be determined based on the highest transmission rate supported by the network standard. The higher the highest transmission rate supported by the network standard, the higher the priority of the network standard.

[0016] The step of causing the communication terminal to enter the RRC connection state may include: initiating a service request to establish an RRC connection without using an application processor of the communication terminal.

[0017] The step of making the communication terminal enter the RRC connection state may include: sending a message to the application processor of the communication terminal that the network wants to send data to the application processor, thereby triggering the application processor to let the communication processor establish a data connection and making the communication terminal enter the RRC connection state.

[0018] The step of prohibiting the communication terminal from entering the DRX state may include: during the access process of the RRC connected state, by setting the parameters reported by the communication terminal indicating the connected state discontinuous reception capability to not be supported, or making the parameters reported by the communication terminal not include the parameters indicating the connected state discontinuous reception capability, to prohibit the network from configuring the DRX state for the communication terminal.

[0019] The step of prohibiting the communication terminal from entering the DRX state may include: in response to the network configuring the DRX state for the communication terminal, rejecting the network's configuration, and sending a rejection response to the network.

[0020] The step of keeping the communication terminal in the RRC connected state may include: when the communication terminal is in the RRC connected state and the communication terminal has not sent and received service data within a predetermined time, periodically sending an uplink scheduling request without using an application processor of the communication terminal, and when the network schedules the communication terminal through a physical downlink control channel and allocates uplink physical shared channel uplink resources, if the communication terminal actually has no uplink service data to be sent, sending a dummy data packet filled with all zeros to the network through the uplink physical shared channel.

[0021] The step of keeping the communication terminal in the RRC connection state may include: in response to the network configuring a measurement control message for the communication terminal for the traffic volume and the traffic volume to be sent by the communication terminal uplink is zero, reporting a non-zero cache status report so that the RRC connection state is not released by the network.

[0022] The step of keeping the communication terminal in the RRC connected state may include: in response to the RRC connected state being released by the network, again making the communication terminal enter and keep the RRC connected state, and prohibiting the communication terminal from entering the DRX state.

[0023] According to some example embodiments, an electronic device includes: an application processor configured to: notify a communication processor that the electronic device enters a predetermined mode; and a communication processor configured to: execute the above-mentioned communication method.

[0041] Figure 1 is a block diagram illustrating an electronic device according to an example embodiment of the present disclosure.

[0042] The electronic device according to various exemplary embodiments of the present disclosure may include, for example, a mobile phone, a tablet personal computer (PC), a personal digital assistant (PDA), etc. However, the present disclosure is not limited thereto, and the electronic device according to the present disclosure may be any communication terminal having a mobile communication function.

[0043] like Figure 1As shown, the electronic device 100 according to an embodiment of the present disclosure may include an application processor (AP) 110 and a communication processor (CP) 120 .

[0044] In some example embodiments, the user interface of the electronic device 100 may be provided with an option to cause the electronic device 100 to enter a predetermined mode (e.g., which may be referred to as an acceleration mode). According to some example embodiments, the user interface may include a button for causing the electronic device 100 to enter the acceleration mode. Here, the acceleration mode may be a mode for reducing the delay in receiving and sending business data of applications installed on the electronic device 100.

[0045] According to some example embodiments, the electronic device 100 may enter the acceleration mode according to a user's command. The user's command may be input to the electronic device 100 in one of a variety of ways. According to some example embodiments, the input may include, but is not limited to, touch input, keyboard input, voice input, gesture input, etc. through a user interface, and the user interface may include, but is not limited to, a touch screen, a keyboard, a microphone, a gesture sensor, etc.

[0046] According to other example embodiments, a command for causing the electronic device 100 to enter the acceleration mode may also be received from a device external to the electronic device 100 .

[0047] The AP 110 may notify the CP 120 that the electronic device 100 enters the acceleration mode upon receiving a command for causing the electronic device 100 to enter the acceleration mode.

[0048] CP 120 may detect the state of radio resource control (RRC) of electronic device 100 in response to electronic device 100 entering the acceleration mode. According to some example embodiments, the RRC of electronic device 100 may be one of an RRC connected state and an RRC idle state, and the RRC connected state may include a discontinuous reception (DRX) state. According to some example embodiments, the DRX state may be referred to as a discontinuous reception (C-DRX) state in a connected state.

[0049] According to some example embodiments, in response to the electronic device 100 being in the RRC connected state, the CP 120 may maintain the electronic device 100 in the RRC connected state regardless of whether the electronic device 100 transmits and receives traffic data.

[0050] For example, in response to the electronic device 100 being in the RRC connected state and not in the DRX state, the CP 120 may keep the electronic device 100 in the RRC connected state and prohibit the electronic device 100 from entering the DRX state.

[0051] For example, in response to the electronic device 100 being in the DRX state, the CP 120 may maintain the electronic device 100 in the DRX state.

[0052] According to some example embodiments, in response to the electronic device 100 being in the RRC idle state, regardless of whether the electronic device 100 sends and receives service data, the CP 120 may cause the electronic device 100 to enter and maintain the RRC connected state, and prohibit the electronic device 100 from entering the DRX state.

[0053] According to some example embodiments, the CP 120 may receive and / or transmit service data of an application installed on the electronic device 100 while maintaining the electronic device 100 in the RRC connected state.

[0054] According to some example embodiments, CP 120 may reduce a series of signaling interactions required when the RRC idle state is changed to the RRC connected state by keeping the electronic device 100 in the RRC connected state, thereby reducing the delay in receiving and / or sending service data of applications installed on the electronic device 100.

[0055] According to some example embodiments, CP 120 may further reduce a delay in receiving and / or transmitting service data of an application installed on electronic device 100 in the RRC connected state by prohibiting electronic device 100 from entering the DRX state.

[0056] According to some example embodiments, since maintaining the RRC connection state of the electronic device 100 in the acceleration mode may increase the power consumption of the electronic device 100, it may be necessary for the electronic device 100 to automatically exit the acceleration mode when the user forgets to exit the acceleration mode.

[0057] According to some example embodiments, the power consumption of the electronic device 100 may be reduced by performing the following operations. For example, when the electronic device 100 enters the acceleration mode, the AP 110 may perform a timing operation, and when the AP 110 performs the timing operation for a specific period of time, the AP 110 notifies the CP 120 that the electronic device 100 exits the acceleration mode. According to some example embodiments, the specific period of time may be a predetermined time.

[0058] In some example embodiments, when the AP 110 performs a timing operation for a predetermined time, the AP 110 may further output a message that the electronic device 100 exits the acceleration mode. For example, the AP 110 may visually output the message through a display module, or may non-visually output the message through voice, vibration, touch, etc. using a speaker module, a haptic module, etc. For example, when the AP 110 performs a timing operation for a predetermined time, the AP 110 may further send a message that the electronic device 100 exits the acceleration mode to an external device.

[0059] In some cases, when the electronic device 100 is in a lower priority network format, the delay in receiving and / or sending the service data of the application installed on the electronic device 100 is greater than that in a higher priority network format. For example, when the electronic device 100 is in a 4G (LTE) network, the delay in receiving and / or sending the service data of the application installed on the electronic device 100 is greater than that in a 5G (NR NSA, SA) network.

[0060] According to some example embodiments, in order to reduce the delay in receiving and / or sending the service data of the application installed on the electronic device 100, the CP 120 may change the network standard in which the electronic device 100 runs or resides, so that the electronic device 100 runs or resides in the highest priority network standard that the electronic device 100 can actually support. Figure 3 A flowchart of the CP 120 changing the network standard in which the electronic device 100 resides is described in detail.

[0061] According to some example embodiments, the priority of the network standard may be determined based on the evolution technology of wireless communication. Generally, with the development of network standards, the maximum transmission rate supported by the network standard is getting higher and higher. Therefore, the priority of the network standard may depend on the maximum transmission rate supported by the network standard. The higher the maximum transmission rate supported by the network standard, the higher the priority of the network standard. For example, among the currently used network standards, the priority of the network standard is: NR SA>NRNSA>LTE>WCDMA>CDMA HRPD>GSM>CDMA 1x.

[0062] Combine the following Figure 2 A flowchart describing a communication method of a communication terminal according to some example embodiments.

[0063] Figure 2 is a flowchart illustrating a communication method of a communication terminal according to an exemplary embodiment of the present disclosure.

[0064] like Figure 2 As shown, in operation S210, in response to the communication terminal (eg, the electronic device 100) entering the acceleration mode (S205), the CP 120 may detect the state of the RRC of the communication terminal.

[0065] It will be appreciated by those skilled in the art that various known methods may be used to detect the RRC state of a communication terminal, and the present invention is not limited to referring to Figure 1 and Figure 2 The way of description.

[0066] In operation S220, in response to the communication terminal being in the RRC idle state, the CP 120 may cause the communication terminal to enter and maintain the RRC connected state, and prohibit the communication terminal from entering the DRX state.

[0067] According to some example embodiments, in response to the communication terminal being in the RRC idle state, CP 120 may initiate a service request to establish an RRC connection without using an application processor of the communication terminal to enable the communication terminal to enter the RRC connected state.

[0068] For example, CP 120 may trigger a stub message sent to CP 120 at an interface module between CP 120 and AP 110, so that CP 120 initiates a service request to establish an RRC connection, and simulates AP to establish a packet switched (PS) service connection. Here, the stub message is a message that simulates AP 110 sending a message for sending a service request to CP 120. In addition, the access cause of the RRC connection may be PS data indicating that there is data to be sent to the network, however, the example is not limited thereto, and the access cause of the RRC connection may also be other causes (e.g., registration, etc.).

[0069] According to some example embodiments, in response to the communication terminal being in the RRC idle state, CP 120 may send a message to AP 110 that the network is going to send data to AP 110, thereby triggering AP 110 to let CP 120 establish a data connection and cause the communication terminal to enter the RRC connected state.

[0070] For example, CP 120 may simulate a process in which the network sends data to AP 110, and send a message to AP 110 that the network is going to send data to AP 110, so as to inform AP 110 that the network is going to send data to AP 110. Here, the network may not actually send data to AP 110. After receiving the message, AP 110 sends a signal for establishing a data connection to CP 120, and CP 120 establishes an RRC connection according to the signal for establishing the data connection.

[0071] According to some example embodiments, during the access process in the RRC connected state, CP 120 may prohibit the network from configuring the DRX state for the communication terminal by setting the parameters reported by the communication terminal indicating the connected state discontinuous reception capability to not be supported, or making the parameters reported by the communication terminal not include the parameters indicating the connected state discontinuous reception capability, so as to prohibit the communication terminal from entering the DRX state.

[0072] According to some example embodiments, when the communication terminal is in the RRC connected state and the network configures the communication terminal with a DRX state, the CP 120 may prohibit the communication terminal from entering the DRX state by rejecting the network's configuration and sending a rejection response to the network. It will be appreciated by those skilled in the art that various known methods (e.g., 3GPP protocol) may be used to reject the network's configuration, and the present invention does not impose any limitation thereto.

[0073] According to some example embodiments, when the communication terminal is in an RRC connected state and the communication terminal does not send and receive service data within a predetermined time (for example, the communication terminal does not send and receive service data for a predetermined time), CP120 may periodically send an uplink scheduling request without using the AP 110 of the communication terminal, so that the RRC connected state is not released by the network, thereby keeping the communication terminal in the RRC connected state.

[0074] In this case, when the network schedules the communication terminal through the physical downlink control channel (Physical Downlink Control Channel, PDCCH) and allocates uplink physical shared channel (Physical Uplink Share Channel, PUSCH) uplink resources, if the communication terminal actually has no uplink service data to send, CP 120 can send a dummy data packet filled with all zeros to the network through PUSCH.

[0075] According to some example embodiments, when the communication terminal is in an RRC connected state, in response to the network configuring a measurement control message for the communication terminal for the traffic volume and the traffic volume to be sent uplink by the communication terminal is zero, CP 120 may report a non-zero cache status report so that the RRC connected state is not released by the network, thereby keeping the communication terminal in the RRC connected state.

[0076] According to some example embodiments, in response to the RRC connected state being released by the network, CP 120 may again cause the communication terminal to enter and remain in the RRC connected state, and prohibit the communication terminal from entering the DRX state.

[0077] In operation S230, in response to the communication terminal being in the RRC connected state, the CP 120 may maintain the communication terminal in the RRC connected state.

[0078] The method of maintaining the communication terminal in the RRC connected state in operation S230 may be similar to the method of maintaining the communication terminal in the RRC connected state in operation S220.

[0079] In operation S240, the CP 120 may receive and / or transmit service data of an application installed on the communication terminal in the RRC connected state.

[0080] Although the above shows a method for making a communication terminal enter an RRC connected state, a method for keeping a communication terminal in an RRC connected state, and a method for prohibiting a communication terminal from entering a DRX state according to an example embodiment of the present disclosure, the present disclosure is not limited thereto, and other existing methods for making a communication terminal enter an RRC connected state, methods for keeping a communication terminal in an RRC connected state, and methods for prohibiting a communication terminal from entering a DRX state may also be used.

[0081] Figure 3 is a flowchart illustrating in more detail a process of maintaining a communication terminal in an RRC connected state in response to the communication terminal being in an RRC connected state according to an exemplary embodiment of the present disclosure.

[0082] like Figure 3 As shown, in operation S310, the CP 120 may detect whether the communication terminal is in the DRX state of the RRC connected state.

[0083] In response to the communication terminal not being in the DRX state, in operation S320, the CP 120 may keep the communication terminal in the RRC connected state and prohibit the communication terminal from entering the DRX state.

[0084] According to some example embodiments, when the communication terminal is in the RRC connected state and the network configures the communication terminal with a DRX state, CP 120 may prohibit the communication terminal from entering the DRX state by rejecting the network's configuration and sending a rejection response to the network.

[0085] The method of maintaining the communication terminal in the RRC connected state in operation S310 may be similar to the method of maintaining the communication terminal in the RRC connected state in operation S220.

[0086] In response to the communication terminal being in the DRX state, in operation S330, the CP 120 may keep the communication terminal in the DRX state.

[0087] The method of maintaining the communication terminal in the DRX state in operation S330 may be similar to the method of maintaining the communication terminal in the RRC connected state in operation S220.

[0088] Figure 4 is a flowchart illustrating a method of causing a communication terminal to camp on a high-priority network system according to an exemplary embodiment of the present disclosure.

[0089] like Figure 4 As shown, in operation S410, the CP 120 may detect the state of the RRC of the communication terminal.

[0090] In operation S420, in response to the communication terminal being in the RRC idle state, the CP 120 may acquire a first network standard with the highest priority that can be supported by a subscriber identity module (SIM) card of the communication terminal.

[0091] In operation S430, the CP 120 may acquire the second network standard with the highest priority that can be supported by the communication terminal.

[0092] Those skilled in the art will appreciate that various known methods may be used to obtain the highest priority first network standard supported by the SIM card of the communication terminal and the highest priority second network standard supported by the communication terminal, and the present invention does not impose any limitation thereto.

[0093] In operation S440, the CP 120 may determine a lower priority network standard among the first network standard and the second network standard as a third network standard which is a highest priority network standard that the communication terminal can actually support.

[0094] In operation S450, CP 120 may determine whether the network standard currently in which the communication terminal resides is the same as the third network standard. Those skilled in the art may understand that various known methods may be used to determine whether the network standard currently in which the communication terminal resides is the same as the third network standard, and the present invention does not impose any limitation thereto.

[0095] In operation S460, in response to the communication terminal currently residing in a network standard that is different from the third network standard, the CP 120 may acquire a fourth network standard with the highest priority that can be supported in the current wireless network environment.

[0096] According to some example embodiments, CP 120 may search for the fourth network standard with the highest priority that can be supported in the current wireless network environment through a Background Public Land Mobile Network (BPLMN) process.

[0097] In operation S470, the CP 120 may determine the network standard with a lower priority between the third network standard and the fourth network standard as the network standard with the highest priority that the communication terminal can actually support, and make the communication terminal camp on the network standard with the highest priority that the communication terminal can actually support.

[0098] Figure 5 A block diagram of an electronic device according to another example embodiment is shown.
