Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic diagram of a system architecture to which a power consumption control method of a terminal according to an embodiment of the present invention is applied; as shown in fig. 1, the system includes a terminal 101, a main base station 102, a secondary base station 103; wherein the content of the first and second substances,
the terminal 101 may establish an air interface connection with the main base station 102 (also referred to as a master node), thereby implementing communication with the main base station 102; the terminal 101 may also establish an air interface connection with the secondary base station 103 (also referred to as a secondary node), so as to implement communication with the secondary base station 103; the terminal 101 may also establish air interface connections with the main base station 102 and the secondary base station 103 at the same time, so as to simultaneously implement communication with the main base station 102 and the secondary base station 103.
In the dual connectivity mode, the terminal 101 establishes two connections with the primary base station 102 and the secondary base station 103 at the same time, where the primary base station 102 is mainly responsible for signaling transmission and the secondary base station 103 is responsible for data transmission. The technical scheme of the embodiment of the application is mainly used for the terminal in the double-connection mode.
The types of the main base station 102 and the secondary base station 103 shown in fig. 1 may be the same or different. In one example, the primary base station 102 is an LTE base station and the secondary base station 103 is an NR base station. In another example, the primary base station 102 is an NR base station, and the secondary base station 103 is also an NR base station. In yet another example, the primary base station 102 is an NR base station and the secondary base station 103 is an LTE base station. The embodiment of the present application does not limit the types of the main base station 102 and the secondary base station 103.
In one example, the dual connection mode is an EN-DC mode or a next generation EN-DC (NGEN-DC) mode, in which case the primary base station is an LTE base station and the secondary base station is an NR base station, and the terminal communicates with both the LTE base station and the NR base station.
In another example, the dual connectivity mode is an NR-evolved UMTS (NR-EUTRA, NE-DC) mode, in which case the primary base station is an NR base station and the secondary base station is an LTE base station, and the terminal communicates with both the LTE and NR base stations.
It should be noted that the dual connection mode is not limited to the EN-DC mode and the NE-DC mode, and the specific type of the dual connection mode is not limited in the embodiment of the present application.
In a specific implementation, the deployment manner of the primary base station and the secondary base station may be co-base deployment (for example, the NR base station and the LTE base station may be disposed on one entity device), or may also be non-co-base deployment (for example, the NR base station and the LTE base station may be disposed on different entity devices), which is not limited in this application. Here, the LTE base station may be referred to as an evolved Node B (eNB), and the NR base station may be referred to as a next generation base station (gNB). It should be noted that the present application may not be limited to the correlation between the coverage areas of the primary base station and the secondary base station, for example, the primary base station and the secondary base station may overlap.
As to the specific type of the terminal 101, the present application may not be limited, and it may be any user equipment that supports the dual connection mode, for example, a smart phone, a personal computer, a notebook computer, a tablet computer, a portable wearable device, and the like.
The application scenario of the embodiment of the present invention may be as follows: in the non-independent 5G networking, when the amount of padding data in the MAC layer packet transmitted between the terminal and the first base station is greater than the data amount threshold, if the terminal still maintains dual connectivity with the primary base station and the secondary base station, the terminal not only communicates with the primary base station and but also communicates with the secondary base station, which may increase the power consumption of the terminal.
The embodiment of the invention provides a power consumption control method of a terminal, which is applied to the terminal and specifically can be the terminal 101 shown in fig. 1. Fig. 2 is a schematic diagram of an implementation flow of a power consumption control method of a terminal according to an embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: the terminal acquires filling data in an MAC layer data packet transmitted between the terminal and the first base station.
Wherein, the padding data may refer to padding data for cyclic redundancy check; and may also refer to padding data that can make the length of the MAC packet within a preset range so as to ensure that the MAC packet is not discarded.
Here, the terminal may refer to a terminal supporting a dual connectivity mode in which the terminal communicates with both a first base station and a second base station; the first base station is an auxiliary base station, and the second base station is a main base station.
Here, in order to realize simultaneous communication with two base stations, the terminal needs to have two sets of communication modules, where the two sets of communication modules correspond to the two base stations respectively. The first modem module (modem) and the first radio frequency path (including the first radio frequency circuit and the first radio frequency antenna) form a first set of communication modules, and the first set of communication modules correspond to the second base station. A second modem module (modem) and a second radio frequency path (including a second radio frequency circuit and a second radio frequency antenna) form a second set of communication modules, the second set of communication modules corresponding to the first base station. In one example, the first modem is a 5G modem, the second modem is a 4G modem, the first radio frequency circuitry is 5G RF, and the second radio frequency circuitry is 4G RF. In the dual connection mode, the first communication module and the second communication module operate simultaneously.
In practical application, taking the EN-DC mode of 5G non-independent networking as an example, the terminal may establish connection with both a main base station, i.e., an LTE base station, and an auxiliary base station, i.e., an NR base station. The LTE base station may be responsible for signaling transmission, and the NR base station may be responsible for data transmission, so that when padding data in an MAC layer packet transmitted between the terminal and the first base station is greater than a data amount threshold, if the terminal is still in communication with the NR base station and the LTE base station, power consumption of the terminal may be too large, and thus standby time of the terminal may be shortened. In order to achieve the best compromise between terminal performance and power consumption, the power consumption of the terminal may be controlled based on padding data in a MAC layer packet transmitted between the terminal and the first base station.
Here, the manner of acquiring the padding data in the MAC layer packet transmitted between the terminal and the first base station is not limited, and the padding data may be acquired periodically or may be acquired in a monitoring manner.
In practical application, the terminal may receive a downlink data packet, that is, an MAC layer data packet, sent by the first base station, and the terminal checks the received MAC layer data packet to obtain a data amount of padding data in the MAC layer data packet. Wherein the MAC packet may include the following fields: preamble, destination MAC address, source MAC address, type, padding (padding), frame check sequence, etc.
Specifically, the terminal may parse the MAC layer packet from the first base station to obtain a data length corresponding to a padding (padding) field of the MAC layer packet, so as to obtain a data amount of padding data in the MAC layer packet.
In an embodiment, the obtaining of padding data in a MAC layer packet transmitted between the first base station and the second base station includes: the terminal receives feedback information from the second base station; the feedback information is used for indicating filling data in an MAC layer data packet sent to the terminal; and determining the data quantity of filling data in the MAC layer data packet transmitted between the terminal and the first base station based on the feedback information.
Here, the terminal may obtain the data length of the padding data in the MAC layer packet using the feedback information of the second base station.
In practical application, the terminal may be provided with a virtual switch, and when a user turns on the virtual switch through touch operation, key operation, voice operation, gesture operation, or the like, the terminal determines that power consumption of the terminal needs to be optimized, and starts to acquire padding data in an MAC layer packet transmitted between the terminal and the first base station.
Based on this, in an embodiment, the acquiring, by the terminal, padding data in a MAC layer packet transmitted between the terminal and the first base station includes: detecting whether a first instruction is received; the first instruction is used for instructing to reduce the power consumption of the terminal; and when the first instruction is determined to be received, the terminal acquires filling data in an MAC layer data packet transmitted between the terminal and the first base station.
For example, as shown in fig. 3, a virtual switch such as "intelligent 5G" may be set on the terminal, and when a user turns on the virtual switch, the terminal determines that power consumption of the terminal needs to be optimized, and starts to acquire padding data in an MAC layer packet transmitted between the terminal and the first base station; when the user closes the virtual switch, the terminal may generate a prompt message such as "after closing the switch, the power consumption of the mobile phone will be increased, and whether the mobile phone is still closed", determine whether a confirmation operation for the prompt message is received, and when it is determined that the confirmation operation is received, the terminal determines that the power consumption of the terminal does not need to be optimized.
Step 202: and if the filling data volume in the MAC layer data packet is larger than a data volume threshold value, controlling the terminal to forbid the dual-connection mode based on a power consumption adjustment strategy.
In an embodiment, if the amount of padding data in the MAC layer packet is greater than a data amount threshold, controlling the terminal to disable the dual connectivity mode based on a power consumption adjustment policy includes:
if the filling data volume in the MAC layer data packet is larger than the data volume threshold value, judging whether the network delay in a preset time length is larger than a delay threshold value; and when the network delay within the preset time length is determined to be larger than a delay threshold, controlling the terminal to forbid the dual-connection mode based on a power consumption adjustment strategy.
Specifically, the terminal may determine the network delay within a preset time according to the ACK response fed back to the first base station.
For example, after receiving the MAC packet sent by the first base station, the terminal sends an ACK response to the first base station, and instructs the first base station to send a next MAC packet; the terminal records a first time for indicating the first base station to send a next MAC data packet and records a second time for receiving the next MAC data packet sent by the first base station; calculating the difference value between the first time and the second time, and taking the difference value as the network time delay; by analogy, counting the network delay within a preset time length; and if the network delay in the preset duration is greater than the delay threshold, controlling the terminal to disable the dual-connection mode based on a power consumption adjustment strategy.
Here, the disabling of the dual connectivity mode may refer to prohibiting the terminal from connecting with the first base station.
Here, the power consumption adjustment policy may refer to a policy capable of preventing the terminal from activating a dual connectivity mode; it may also refer to a policy that can reduce the probability of the terminal activating the dual connectivity mode. Specifically, the following three methods can be included:
the first power consumption adjustment strategy is as follows: and the terminal sends wireless capability information to the second base station through a TAU flow so as to prevent the network equipment from configuring a dual connection mode, further prevent the terminal from activating the dual connection mode and finally control the terminal to disable the dual connection mode. Wherein the wireless capability information is used for indicating that the terminal does not support the access of the first base station.
The second power consumption adjustment strategy: and the terminal sends wireless capability information to the second base station through a re-registration process so as to prevent the network equipment from configuring a dual-connection mode, further prevent the terminal from activating the dual-connection mode and finally control the terminal to disable the dual-connection mode. Wherein the wireless capability information is used for indicating that the terminal does not support the access of the first base station.
The third power consumption adjustment strategy: and the terminal controls to disable the double connection mode by closing a communication module which communicates with the first base station.
In practical application, if the terminal actively sends the information indicating that the wireless capability of the first base station is not supported to the second base station, the second base station can be prevented from configuring a dual connection mode for the terminal, and further the terminal can be prevented from activating the dual connection mode, so that the problem that the terminal still communicates with the first base station and the second base station under the condition that the filling data volume of an MAC layer data packet is larger than a data volume threshold value, and the electric quantity of the terminal is rapidly reduced can be avoided.
Based on this, in an embodiment, the controlling the terminal to disable the dual connection mode based on the power consumption adjustment policy includes: transmitting wireless capability information to a second base station; the wireless capability information is used for indicating that the terminal does not support the access of the first base station.
For example, taking an EN-DC mode of a 5G non-independent networking as an example, the wireless capability information may be sent to a main base station in the network device, that is, an LTE base station; the wireless capability information is used for indicating that the terminal does not support the access of a secondary base station (NR base station).
In practical application, the terminal may send, to the second base station, information indicating that the wireless capability information that the first base station is not supported for access is sent by using the first power consumption adjustment policy, so as to avoid the network device from configuring a dual connectivity mode, further avoid the terminal from activating the dual connectivity mode, and finally control the terminal to disable the dual connectivity mode.
Based on this, in an embodiment, the sending wireless capability information to the second base station includes: sending a TAU request to the second base station; the TAU request carries first indication information; the first indication information is used for indicating that the terminal needs to update wireless capability information; receiving a capability reporting indication message sent by the second base station based on the TAU request; and sending the wireless capability information to the second base station according to the capability reporting indication message.
For example, taking an EN-DC mode of a 5G non-independent networking as an example, after the terminal is disconnected from an auxiliary base station, that is, an NR base station, if the current state of the terminal is an idle state, the terminal needs to establish an RRC connection with an LTE base station first, and then initiate a TAU procedure to the LTE base station to indicate that the terminal does not support access of the auxiliary base station, that is, the NR base station. If the current state of the terminal is a connection state, the terminal can directly initiate a TAU flow to an LTE base station so as to indicate that the terminal does not support the access of an auxiliary base station, namely an NR base station; if the current state of the terminal is a dual-connection state, the terminal can send a secondary cell group failure information message to an LTE base station to indicate that the connection between the terminal and the first base station fails, the LTE base station can send dual-connection failure indication information to the terminal, and after the terminal is disconnected from an NR base station, a TAU flow is initiated to the LTE base station to indicate that the terminal does not support the access of a secondary base station, namely the NR base station. The idle state may refer to that the terminal does not establish a connection with a main base station, that is, an LTE base station, and the connection state may refer to that the terminal has established a connection with the main base station, that is, the LTE base station.
Here, the value of the first indication information may include 0 or 1, where when the value of the first indication information is 1, it may indicate that the terminal needs to update the wireless capability information; when the value of the first indication information is 0, it may be indicated that the terminal does not need to update the wireless capability information.
Table 1 is a schematic table of the format of the TAU request. As shown in table 1, the TAU request may carry byte 1, i.e. octet1, where the URC upd characterizes whether the UE radio capability information needs to be updated. The bit positions occupied by the URC upd in the TAU request are shown in table 1. As shown in table 1, the URC upd may be the 1 st bit corresponding to the lowest bit in byte 1.
TABLE 1
Table 2 is a schematic table of values of URC upd. As shown in table 2, when the value of URC upd is 0, it indicates that the UE radio capability information does not need to be updated. And when the value of the URC upd is 1, indicating that the UE wireless capability information needs to be updated.
TABLE 2
In practical application, in order to further improve the standby time of the terminal, the terminal may further send, to the second base station, indication information indicating that the tracking area returns to an idle state after being updated.
Based on this, in an embodiment, the TAU request further carries second indication information; the second indication information is used for indicating that the state of the terminal returns to an idle state from a connected state after the tracking area is updated.
The idle state may refer to disconnection between the terminal and the second base station, and the connection state may refer to connection between the terminal and the second base station.
Here, the value of the second indication information may include 0 or 1, where when the value of the second indication information is 0, it may indicate that the state of the terminal needs to be returned from the connected state to the idle state after the tracking area is updated; when the value of the second indication information is 1, it may be indicated that the state of the terminal does not need to return from the connected state to the idle state after the tracking area is updated.
For example, an "active flag" of an "EPS update type" in the TAU request may be set to 0, indicating that the state of the terminal needs to be returned from the connected state to the idle state after the tracking area is updated.
It should be noted that, here, the terminal sends the second indication information to the network side device, so that the terminal may return to an idle state as soon as possible after the tracking area update is completed. Because the power consumption of the terminal in the idle state is less than that in the connected state, the power consumption can be further reduced, and the standby time of the terminal is prolonged.
In practical application, the terminal may also actively send, to the second base station, information indicating that the wireless capability information to which the first base station is not supported by the access is sent by using the second power consumption adjustment policy, so as to avoid the network device from configuring a dual connectivity mode and further avoid the terminal from activating the dual connectivity mode, and thus, the problem that the terminal still communicates with the second base station and the first base station when the amount of filling data in an MAC layer packet is greater than a data amount threshold value, so that the electric quantity of the terminal is rapidly reduced can be avoided.
Based on this, in an embodiment, the sending the wireless capability information to the first master base station includes: and transmitting the wireless capability information to the second base station in the process of re-registering to the network equipment.
Here, the terminal may transmit a re-registration request message to the second base station; and in the process of re-registering to the network equipment, sending the wireless capability information to the second base station; receiving a capability reporting indication message sent by the second base station; and sending the wireless capability information to the second base station according to the capability reporting indication message.
Here, the terminal may further carry the wireless capability information in a re-registration request message; and sending a re-registration request message carrying the wireless capability information to the network equipment.
In practical application, the terminal may further use the third power consumption adjustment policy to control disabling of the dual connectivity mode by actively closing a communication module that communicates with the first base station.
Based on this, in an embodiment, the controlling the terminal to disable the dual connection mode based on the power consumption adjustment policy includes: and the terminal controls to disable the double connection mode by closing a communication module which communicates with the first base station.
Wherein the communication module of the terminal for communicating with the first base station may be formed by a second modem module (modem) and a second radio frequency path (including a second radio frequency circuit and a second radio frequency antenna).
In an example, the second modem can be a 5G modem and the second radio frequency circuit can be a 5G RF.
In practical application, after the terminal is forbidden to be connected with the first base station, the terminal continues to acquire the filling data volume in the MAC layer data packet, and when the filling data volume is smaller than or equal to a data volume threshold value, the terminal is controlled to enable the dual-connection mode according to the power adjustment strategy.
Based on this, in an embodiment, the method further comprises: and if the filling data volume in the MAC layer data packet is less than or equal to a data volume threshold value, controlling the terminal to enable the dual-connection mode based on a power consumption adjustment strategy.
Here, the process of controlling the terminal to switch from the single connection mode to the dual connection mode based on the power adjustment policy is similar to the process of controlling the terminal to disable the dual connection mode, and is not described herein again.
By adopting the technical scheme of the embodiment of the invention, when the filling data in the MAC layer data packet transmitted between the terminal and the first base station is larger than the data volume threshold value, the terminal is controlled to disable the double-connection mode based on the power consumption adjustment strategy, so that the problem of overlarge power consumption caused by the terminal working in the double-connection mode can be avoided, the electric quantity consumed by the terminal can be reduced, and the standby time of the terminal is prolonged.
In addition, if the padding data in the MAC layer packet transmitted between the terminal and the first base station is greater than the data amount threshold, the terminal may notify the second base station through a TAU procedure or a re-registration procedure that the terminal does not support the access of the first base station, so as to remain in the single connection mode, and may also actively close a communication module that communicates with the first base station, so as to implement the fallback from the dual connection mode to the single connection mode.
The following describes in detail a power consumption control method of a terminal according to an embodiment of the present invention with reference to a specific embodiment.
Fig. 4 is a schematic diagram of an implementation process of implementing a disabled dual connectivity mode by a terminal through a TAU flow in the embodiment of the present invention, where the method includes:
step 401: the terminal sends a TAU request to the second base station.
Here, if padding data in a MAC layer packet transmitted between the terminal and the first base station is greater than a data amount threshold, the terminal may transmit a TAU request to the second base station.
Here, the terminal supports a dual connectivity mode in which the terminal communicates with both the first base station and the second base station; the first base station is an auxiliary base station, and the second base station is a main base station.
Here, if the current state of the terminal is an idle state, the terminal needs to establish an RRC connection with the second base station first, and then initiate a TAU procedure to the second base station to indicate that the terminal does not support the access of the first base station; if the current state of the terminal is the connection state, the terminal may directly initiate a TAU procedure to the second base station to indicate that the terminal does not support the access of the first base station.
Here, the TAU request carries first indication information; the first indication information is used for indicating that the terminal needs to update wireless capability information; the wireless capability information is used for indicating that the terminal does not support the access of the first base station.
For example, the value of URC upd in the TAU request is set to 1, which indicates that the terminal needs to update the radio capability information.
Here, the TAU request also carries second indication information; the second indication information is used for indicating that the state of the terminal returns to an idle state from a connected state after the tracking area is updated.
For example, an active flag of the "EPS update type" in the TAU request is set to 0, which indicates that the state of the terminal needs to be returned from the connected state to the idle state after the tracking area is updated. The idle state may refer to disconnection of the terminal from the second base station.
Step 402: and the second base station sends a capability reporting indication message to the terminal based on the TAU request.
Step 403: and the terminal sends the wireless capability information to the second base station according to the capability reporting indication message.
Here, after the second base station transmits and receives the wireless capability information, the second base station does not configure the dual connectivity mode for the terminal, thereby controlling the terminal to disable the dual connectivity mode.
Step 404: and the second base station informs the terminal to return to an idle state.
Here, the second base station notifies the terminal to return from the connected state to the idle state after the tracking area is updated according to the second indication information.
It should be noted that, here, when the padding data in the MAC layer packet transmitted between the terminal and the first base station is greater than the data amount threshold, for example, 20%, the terminal notifies the second base station that the terminal needs to disable the connection capability with the first base station by initiating a TAU procedure, so as to maintain the single connection mode. Although the terminal supports the dual connectivity mode, the terminal can actively select not to communicate with the secondary base station in the non-independent networking, and compared with a mode that the terminal needs to communicate with both the main base station and the secondary base station in the related art, the power consumption of the terminal in communicating with the two base stations can be reduced, and further the standby time of the terminal is prolonged.
In addition, the terminal may return to an idle state as soon as possible after the tracking area update is completed. Because the power consumption of the terminal in the idle state is less than that in the connection state, the power consumption can be further reduced, and the standby time of the terminal is prolonged.
In order to implement the power consumption control method of the terminal in the embodiment of the invention, the embodiment of the invention also provides a power consumption control device of the terminal.
