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 for network connection 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 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 NR Dual connection (EN-DC) mode or a next generation EN-DC (next generation EN-DC) mode, in which case, the main base station is an LTE base station, 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-independent 5G networking, when a terminal determines that it needs to disconnect from a secondary base station, if the terminal still maintains dual connectivity with a primary base station and a secondary base station, the terminal not only communicates with the primary base station and but also communicates with the secondary base station, which may cause power consumption, so that the power consumption of the terminal may increase.
The embodiment of the invention provides a network connection control method, which is applied to a terminal, and specifically can be the terminal 101 shown in fig. 1. Fig. 2 is a schematic flow chart illustrating an implementation of a network connection control method according to an embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: if the terminal meets a first preset condition, the terminal determines that the terminal works in a dual-connection mode;
when the terminal meets the first preset condition, representing that the terminal needs to forbid the dual-connection mode; the terminal needing to disable the dual connection mode may refer to the terminal falling back from the dual connection mode to the single connection mode, for example, the terminal needing to disconnect from the second base station.
Step 202: the terminal sends a measurement report to a first base station;
the measurement report is used for indicating that the signal quality of a network of a second base station where the terminal is located is lower than a threshold value, so that the first base station issues a first message according to the measurement report;
step 203: the terminal receives the first message and releases the connection with a second base station according to the first message;
wherein, in the dual connectivity mode, 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, in step 201, in actual application, the terminal may obtain a network connection speed of the first base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines that a first preset condition is met. The terminal can also acquire the number of foreground application programs; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines that a first preset condition is met.
Here, in actual use, the terminal may transmit the measurement report to the first base station in the following manner.
In the first mode, when the terminal determines that the terminal needs to return from the dual connection mode to the single connection mode, if the terminal determines that the terminal works in the dual connection mode, the terminal sends the measurement report to the first base station.
In the second mode, when the terminal determines that the terminal needs to return from the dual connection mode to the single connection mode, if the terminal determines that the terminal works in the dual connection mode and is in a screen-off state, the terminal sends the measurement report to the first base station.
And in the third mode, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, and under the condition that the connection mode control function of the terminal is started, if the terminal determines that the terminal works in the dual-connection mode, the terminal sends the measurement report to the first base station.
In the fourth mode, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, if the terminal determines that the terminal works in the dual-connection mode, the terminal measures the signal quality of the second base station; and when the measured signal quality is greater than or equal to the reporting threshold, sending a measurement report to the first base station.
Wherein, the reporting threshold can be configured by the network side; or may be terminal pre-configured.
In a fifth mode, when the terminal determines that the terminal needs to return from the dual connectivity mode to the single connectivity mode, if the terminal determines that the terminal works in the dual connectivity mode, the terminal periodically sends a measurement report to the first base station.
For example, the terminal reports a measurement report every 1 minute, and the measurement report reported each time indicates that the signal quality of the network of the second base station is low.
In practical application, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, if the terminal determines that the terminal works in the dual-connection mode, the terminal sends the measurement report to the first base station.
Based on this, in an embodiment, the terminal sends a measurement report to the first base station, including:
the method comprises the steps that under the condition that a terminal meets a first preset condition, the terminal detects whether a first communication module communicated with a first base station is started or not; detecting whether a second communication module communicated with a second base station is started or not;
and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual-connection mode and sends a measurement report to the first base station.
Fig. 3 is a structural diagram of a communication module of a terminal in a dual connectivity mode, and as shown in fig. 3, in order to implement 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 communication module, and the first set of communication modules corresponds to the first base station. The second modem module (modem) and the second radio frequency path (including the second radio frequency circuit and the second radio frequency antenna) form a second communication module, and the second set of communication module corresponds to the 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. It is understood that, if the communication module is integrated in a dual System-on-a-chip (SoC) chip, the method is also applicable to the case of switching from the dual-connection mode to the single-connection mode, and the description of the single-dual connection is not limited to the communication structure of the single-dual modem connection conversion. It should be noted that, in practical applications, when the terminal does not implement the dual connection mode through two sets of communication modules, it is within the protection scope of the embodiment of the present invention as long as the terminal is switched from the dual connection mode to the single connection mode.
In an example, taking the first base station as an LTE base station and the second base station as an NR base station as an example, an implementation flow diagram for a terminal to send a measurement report to the first base station is described, as shown in fig. 4, including:
step 1: the terminal determines to fall back to the single connection mode.
For example, the terminal acquires the network connection speed of the LTE base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Or, the terminal may further obtain the number of foreground applications; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Step 2: the terminal judges whether the terminal works in a double-connection mode.
The terminal detects whether a first communication module communicating with an LTE base station is started; detecting whether a second communication module communicated with the NR base station is started or not; and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual connection mode.
And step 3: and when determining that the terminal works in the dual-connection mode, the terminal sends a measurement report to the first base station.
The measurement report is used to indicate that the signal quality of the network of the NR base station where the terminal is located is low.
In this example, when the terminal determines to fall back to the single connection mode for communicating with the LTE base station, if the terminal determines that the terminal itself operates in the dual connection mode, the terminal sends the measurement report to the LTE base station to indicate that the signal quality of the network of NR base stations is below the threshold.
In practical application, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, if the terminal determines that the terminal works in the dual-connection mode and is in a screen-off state, the terminal sends the measurement report to the first base station.
Based on this, in an embodiment, the terminal sends a measurement report to the first base station, including:
judging whether the screen state of the terminal is a screen-off state;
and when the screen state of the terminal is the screen off state, the terminal sends a measurement report to the first base station.
Specifically, the terminal acquires the screen brightness of the terminal; and when the acquired screen brightness is less than or equal to the brightness threshold, determining that the screen state of the terminal is a screen-off state.
In an example, taking the first base station as an LTE base station and the second base station as an NR base station as an example, an implementation flow diagram for a terminal to send a measurement report to the first base station is described, as shown in fig. 5, including:
step 1: the terminal determines to fall back to the single connection mode.
For example, the terminal acquires the network connection speed of the LTE base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Or, the terminal may further obtain the number of foreground applications; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Step 2: the terminal judges whether the terminal works in a double-connection mode.
The terminal detects whether a first communication module communicating with an LTE base station is started; detecting whether a second communication module communicated with the NR base station is started or not; and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual connection mode.
And step 3: when the terminal is determined to work in a double-connection mode, judging whether the screen state of the terminal is a screen-off state;
and 4, step 4: and when the screen state of the terminal is the screen off state, the terminal sends a measurement report to the first base station.
In this example, when the terminal determines to fall back to the single connection mode for communicating with the LTE base station, if the terminal determines that the terminal itself operates in the dual connection mode and is in a screen-off state, the terminal sends the measurement report to the LTE base station to indicate that the signal quality of the network of the NR base station is lower than the threshold.
In practical application, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, and under the condition that the connection mode control function of the terminal is started, if the terminal determines that the terminal works in the dual-connection mode, the terminal sends the measurement report to the first base station.
Based on this, in an embodiment, if the terminal satisfies the first preset condition, the determining, by the terminal, that the terminal is operating in the dual connectivity mode includes:
if the terminal meets a first preset condition, when the connection mode control function of the terminal is started, the terminal determines that the terminal works in a dual-connection mode.
Here, the terminal may be provided with a virtual switch, and when the user turns on the virtual switch through a touch operation, a key operation, a voice operation, a gesture operation, or the like, it is determined that the connection mode control function of the terminal is turned on.
In an example, taking the first base station as an LTE base station and the second base station as an NR base station as an example, an implementation flow diagram for a terminal to send a measurement report to the first base station is described, as shown in fig. 6, including:
step 1: the terminal determines to fall back to the single connection mode.
For example, the terminal acquires the network connection speed of the LTE base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Or, the terminal may further obtain the number of foreground applications; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Step 2: the terminal judges whether the connection mode control function is turned on.
And step 3: when the connection mode control function is started, the terminal judges whether the terminal works in a dual connection mode.
The terminal detects whether a first communication module communicating with an LTE base station is started; detecting whether a second communication module communicated with the NR base station is started or not; and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual connection mode.
And 4, step 4: and when determining that the terminal works in the dual-connection mode, the terminal sends a measurement report to the first base station.
In this example, when the terminal determines to fall back to the single connection mode for communicating with the LTE base station, and when the connection mode control function of the terminal is turned on, if the terminal determines that the terminal itself operates in the dual connection mode, the terminal transmits the measurement report to the LTE base station to indicate that the signal quality of the network of the NR base station is lower than the threshold.
In practical application, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, if the terminal determines that the terminal works in the dual-connection mode, the terminal measures the signal quality of the second base station; and when the measured signal quality is greater than or equal to the reporting threshold, sending a measurement report to the first base station.
Based on this, in an embodiment, the terminal sends a measurement report to the first base station, including:
the terminal measures to obtain a first parameter value; the first parameter value characterizes a signal quality of the second base station;
and the terminal sends a measurement report to the first base station based on the first parameter value.
Wherein the signal quality of the second base station comprises one of:
reference Signal Received Power (RSRP);
reference Signal Received Quality (RSRQ), Reference Signal Receiving Quality;
signal to Interference plus Noise Ratio (SINR).
In an example, taking the first base station as an LTE base station and the second base station as an NR base station as an example, an implementation flow diagram for a terminal to send a measurement report to the first base station is described, as shown in fig. 7, including:
step 1: the terminal determines to fall back to the single connection mode.
For example, the terminal acquires the network connection speed of the LTE base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Or, the terminal may further obtain the number of foreground applications; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Step 2: the terminal judges whether the terminal works in a double-connection mode.
The terminal detects whether a first communication module communicating with an LTE base station is started; detecting whether a second communication module communicated with the NR base station is started or not; and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual connection mode.
And step 3: when determining whether the terminal works in the dual-connection mode, the terminal measures the signal quality of the second base station;
and 4, step 4: and when the measured signal quality is greater than or equal to the reporting threshold, the terminal sends a measurement report to the first base station.
In this example, when the terminal determines to fall back to the single connection mode for communicating with the LTE base station, if the terminal determines that the terminal itself operates in the dual connection mode, and detects that the measured signal quality of the second base station is greater than or equal to the reporting threshold, the terminal sends a measurement report to the first base station to indicate that the signal quality of the network of the NR base station is lower than the threshold.
In practical application, when the terminal determines that the terminal needs to return from the dual-connection mode to the single-connection mode, if the terminal determines that the terminal works in the dual-connection mode, the terminal periodically sends a measurement report to the first base station.
Based on this, in an embodiment, the terminal sends a measurement report to the first base station, including:
the terminal periodically sends a measurement report to the first base station.
In an example, taking the first base station as an LTE base station and the second base station as an NR base station as an example, an implementation flow diagram for a terminal to send a measurement report to the first base station is described, as shown in fig. 8, including:
step 1: the terminal determines to fall back to the single connection mode.
For example, the terminal acquires the network connection speed of the LTE base station; and if the acquired network connection speed is greater than or equal to the speed threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Or, the terminal may further obtain the number of foreground applications; and if the number of the acquired foreground application programs is less than or equal to the number threshold, the terminal determines to fall back to the single connection mode for communicating with the LTE base station.
Step 2: the terminal judges whether the terminal works in a double-connection mode.
The terminal detects whether a first communication module communicating with an LTE base station is started; detecting whether a second communication module communicated with the NR base station is started or not; and when the first communication module is determined to be started and the second communication module is started, the terminal determines that the terminal works in a dual connection mode.
And step 3: and when determining whether the terminal works in the dual-connection mode, the terminal measures the signal quality of the second base station and generates a measurement report.
And 4, step 4: the terminal sends a measurement report to the first base station.
The terminal periodically sends a measurement report to the first base station.
In this example, when the terminal determines to fall back to the single connection mode for communicating with the LTE base station, if the terminal determines that the terminal itself operates in the dual connection mode, the measured signal quality of the second base station is used to generate a measurement report, and the measurement report is periodically sent to the first base station to indicate that the signal quality of the network of the NR base station is lower than the threshold.
In practical application, after receiving a measurement report reported by a terminal, a first base station sends a first message to the terminal to guide the terminal to perform connection reconfiguration, and the terminal releases connection with a second base station according to the guidance of the first message in the reconfiguration process.
Based on this, in an embodiment, the method further comprises:
the terminal receives the first message sent by the first base station through RRC signaling;
