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 applied to a control method according to an embodiment of the present invention; as shown in fig. 1, the system includes a terminal 101, a main base station 102, a secondary base station 103; wherein,
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.
For a specific type of the terminal 101, the present application may not be limited, and it may be any user equipment that supports the above 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 invention can be as follows: in the non-standalone networking of 5G, the terminal may disconnect or disconnect from the secondary base station in a specific case, thereby remaining in the single connection mode. When the terminal is in the single connection mode, if the packet loss rate of the PDCP layer packet transmitted between the terminal and the main base station is greater than the packet loss rate threshold, that is, the network quality between the terminal and the main base station is poor, the terminal needs to restart the dual connection mode to recover the connection with the auxiliary base station.
The embodiment of the invention provides a control method, which is applied to a terminal, and specifically can be the terminal 101 shown in fig. 1. FIG. 2 is a schematic diagram of a flow chart of a control method according to an embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: the terminal acquires a first parameter transmitted between the terminal and the first base station.
Wherein the first parameter characterizes a packet loss rate of a PDCP layer packet.
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 a main base station, and the second base station is an auxiliary base station.
Here, the criterion for judging whether the network quality between the terminal and the first base station is good or bad may be a packet loss rate of PDCP layer packets transmitted between the terminal and the first base station.
The packet loss rate may be an index for measuring the transmission accuracy of the data packet within a predetermined time. The packet loss rate is equal to the ratio of the number of packets lost in transmission to the total number of packets transmitted.
Here, the method for obtaining the packet loss rate of the PDCP layer packet is not limited, and may be obtained periodically or in a monitoring manner.
In practical application, the terminal may send a PDCP layer packet to the first base station, the first base station checks the received PDCP layer packet, and when it is checked that a packet loss occurs in the PDCP layer packet, the first base station may feed back the number of lost PDCP layer packets to the terminal, so that the terminal may count the packet loss rate of the PDCP layer packet based on the number of lost PDCP layer packets.
Based on this, in an embodiment, the acquiring, by the terminal, the first parameter transmitted between the terminal and the first base station includes:
the terminal receives feedback information from the first base station; the feedback information is used for indicating the number of the lost PDCP layer packets; determining a first parameter transmitted between the terminal and a first base station based on the feedback information.
Further, in an embodiment, the terminal transmits PDCP layer packets to the first base station; the PDCP layer data packet is used for checking by the first base station; and when the first base station checks that the PDCP layer data packet is lost, receiving feedback information sent by the first base station.
For example, the terminal sends 10 PDCP layer packets to the first base station, and if the terminal receives feedback information indicating that the 2 nd and 4 th packet are lost by the first base station, the terminal may calculate a ratio of packet loss rate of the PDCP layer packets to 2 and 10, that is, 20%.
In practical application, the terminal may further obtain, through the processor of the terminal, a packet loss rate of a PDCP layer packet transmitted between the terminal and the first base station.
Specifically, the terminal may query a packet loss rate of PDCP layer packets transmitted between the terminal and the first base station by the processor executing a specific command.
In practical application, a virtual switch may be disposed on the terminal, 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 the first parameter transmitted to the first base station needs to be acquired.
Based on this, in an embodiment, the acquiring, by the terminal, a packet loss rate of a PDCP layer packet transmitted between the terminal and the first base station includes: detecting whether a first instruction is received; and when the first instruction is determined to be received, the terminal acquires a first parameter transmitted between the terminal and the first base station.
For example, taking the communication function corresponding to the second base station as a 5G function as an example, referring to fig. 3, fig. 4 is a schematic diagram of turning on the intelligent 5G by the terminal, where turning on the intelligent 5G means optimizing the 5G function, and specifically, the terminal can recover to use the 5G function in combination with an actual situation. As shown in fig. 3, the terminal turning on the smart 5G includes the following processes:
step 1: the terminal judges whether the operation of opening the intelligent 5G is received.
Here, the terminal displays a user interface including an option to start the smart 5G, and the user may trigger an operation to select the option corresponding to the smart 5G, thereby starting the smart 5G. Here, the operation by the user may be a touch operation, a key operation, a voice operation, a gesture operation, or the like.
Step 2: and if the operation of opening the intelligent 5G is received, optimizing the 5G function.
Here, the optimization of the 5G function includes at least: and when the signal quality of the 4G network is poor, restoring the connection of the terminal and the second base station.
And step 3: if the control instruction for opening the 5G function is not received, the 5G function is not optimized.
Step 202: and if the first parameter meets a preset condition, starting connection with the second base station.
The preset condition represents that the packet loss rate of the PDCP layer data packet is greater than a packet loss rate threshold value, and the first parameter meets the preset condition, which indicates that the network quality between the terminal and the first base station is poor.
Here, the opening of the connection with the second base station may refer to that the terminal re-opens a dual connection mode, that is, the terminal has a function of establishing a connection with the second base station.
Here, after the connection with the second base station is opened, the terminal may establish a connection with the second base station based on a dual connectivity restoration policy.
Here, the policy for recovering dual connectivity 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. The method specifically comprises the following steps:

The single connection mode may refer to the terminal establishing a connection with the first base station.
The second recovery dual connectivity strategy: the current mode of the terminal is a single connection mode, the terminal sends wireless capability information to the first base station through a Tracking Area Update (TAU) process so that the first base station configures a double connection mode for the terminal, the terminal activates the double connection mode, and finally the terminal is controlled to be switched from the single connection mode to the double connection mode. Wherein the wireless capability information is used for indicating that the terminal supports the access of the second base station.
The third recovery dual connectivity strategy: the current mode of the terminal is a single connection mode, the terminal sends wireless capability information to the first base station through a re-registration process so that the first base station configures a double connection mode for the terminal, the terminal activates the double connection mode, and finally the terminal is controlled to be switched from the single connection mode to the double connection mode. Wherein the wireless capability information is used for indicating that the terminal supports the access of the second base station.
Here, in an embodiment, after the connection with the second base station is opened, the method further includes:

and establishing connection with the second base station by using the configuration information.
In practical application, the terminal may report the measurement report of the second base station to the first base station in advance based on a first recovery dual connectivity policy, so that the first base station configures a dual connectivity mode for the terminal, and further activates the dual connectivity mode, and finally controls the terminal to switch from the single connectivity mode to the dual connectivity mode.
Based on this, in an embodiment, the receiving the configuration information sent by the first base station includes:
updating the reporting threshold of the measurement report from a first threshold to a second threshold; the second threshold is less than the first threshold;
sending a measurement report of the second base station to the first base station when the measurement value of the second base station is greater than the second threshold; the measurement report is used for the first base station to configure a dual connectivity mode for the terminal;
and receiving the configuration information sent by the first base station.
Here, the terminal may report the measurement report of the second base station to the first base station in advance by reducing a reporting threshold of the measurement report, so that the first base station configures a dual connectivity mode for the terminal, and further activates the dual connectivity mode, and finally controls the terminal to switch from the single connectivity mode to the dual connectivity mode.
Further, in an embodiment, the method further comprises:
receiving a measurement request sent by the first base station; the measurement request is used for indicating the terminal to measure the second base station;
and measuring the second base station according to the measurement request to obtain the measurement value.
In practical application, the terminal may send the wireless capability information to the first base station based on a second recovery dual connectivity policy, that is, through a TAU procedure, so that the first base station configures a dual connectivity mode for the terminal, so that the terminal activates the dual connectivity mode, and finally controls the terminal to switch from the single connectivity mode to the dual connectivity mode.
Based on this, in an embodiment, the receiving the configuration information sent by the first base station includes:
transmitting wireless capability information to the first base station; the wireless capability information is used for indicating that the terminal supports the access of the second base station; the wireless capability information is used for the first base station to configure a dual connectivity mode for the terminal;
and receiving the configuration information sent by the first base station.
Further, in an embodiment, the sending wireless capability information to the first base station includes: sending a TAU request to the first 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 first base station based on the TAU request; and sending the wireless capability information to the first base station according to the capability reporting indication message.
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.
In practical application, the terminal may send the wireless capability information to the first base station based on a third dual connectivity recovery strategy, that is, through a re-registration procedure, so that the first base station configures a dual connectivity mode for the terminal, so that the terminal activates the dual connectivity mode, and finally controls the terminal to switch from the single connectivity mode to the dual connectivity mode.
Based on this, in an embodiment, the sending wireless capability information to the first base station includes: transmitting the wireless capability information to the first base station during a re-registration process with a network device.
Specifically, the terminal may transmit a re-registration request message to the first base station; and in the process of re-registering to the network equipment, sending the wireless capability information to the first base station; receiving a capability reporting indication message sent by the first base station; and sending the wireless capability information to the first 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 the embodiment of the application, after the connection is established between the terminal and the second base station, the terminal can communicate with the second base station, so that the dual-connection mode is realized. It should be noted that the connection described in the embodiments of the present application refers to access.

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 corresponds to the first 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, which correspond to a second base station. In one example, the first modem is a 4G modem, the second modem is a 5G modem, the first radio frequency circuitry is 4G RF, and the second radio frequency circuitry is 5G RF. In the dual connection mode, the first communication module and the second communication module operate simultaneously.
In an example, taking the first network as a 5G network (which may also be referred to as an NR network) and the second network as a 4G network (which may also be referred to as an LTE network), the terminal is in an LTE mode (single connection mode), and a process of the terminal recovering the dual connection mode is described.

and 4, step 4: and the terminal reports the measurement report of the second base station to the first base station in advance so that the first base station configures a double-connection mode for the terminal, the terminal activates the double-connection mode, and the terminal is controlled to be switched from the single-connection mode to the double-connection mode.
In an example, taking the first network as a 5G network (which may also be referred to as an NR network) and the second network as a 4G network (which may also be referred to as an LTE network), the terminal is in an LTE mode (single connection mode), and a process of the terminal recovering the dual connection mode is described.
