Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With the development of communication technology, the 5G era has come, and 5G has characteristics of low delay, high rate, high reliability and the like compared with 4G. Some operators consider rapid deployment and cost, most of the currently deployed networks are NSA (non-independent networking) architecture networks, and accordingly, electronic devices need to camp in a dual connectivity form (endec, EUTRA, NRdual connectivity), that is, 4G +5G are connected simultaneously, 4G can be used as a control plane, and 5G can be used as a user plane. Compared with the common 4G electronic equipment (supporting 4G/3G/2G standard), the NSA 5G electronic equipment (supporting 5G/4G/3G/2G) has larger power consumption.

The concrete mainly embodies in the following aspects: double connection: the 4G and the 5G work simultaneously, and the power consumption is naturally higher than that of the single registration in the 4G; the scheduling is more frequent: 5G supports smaller service scheduling; the working bandwidth is higher: the maximum bandwidth supported by 5G sub-6G is 100MHZ, the maximum bandwidth supported by millimeter waves is 400MHZ, and the maximum bandwidth supported by 4G is 20 MHZ; the number of accesses increases: the terminal firstly searches and accesses the 4G cell, and then completes the synchronization and the access of the 5G base station according to the auxiliary information sent by the 4G base station; the measurement is more frequent: the 5G electronic device needs to measure multiple beams in a single cell, and the 4G electronic device only needs to measure a single beam in each cell.

Currently, electronic equipment integrated with a communication baseband chip provider is used to display that 5G consumes 137mA to 292mA more power than 4G and the average is 222mA more power for typical use scenes of users, such as standby, web browsing, downloading, video watching, game testing and the like. The default of 5G electronic equipment is to access 5G under a 5G environment, the standby time of the whole machine is shorter than that of accessing 4G, and the method of prolonging the standby time by expanding the battery capacity brings cost and weight problems, which are difficult to accept for the electronic equipment and users.

In order to solve the above technical problem, embodiments of the present invention provide a network switching method and an electronic device.

For ease of understanding, the concepts involved in the embodiments of the present invention will be described first.

The 5G network priority access mode refers to that 5G is preferentially registered under the condition that 5G signals are covered and the network access requirement is met.

The 4G network priority access mode refers to priority registration of 4G regardless of the presence or absence of 5G signal coverage.

It should be noted that, in the embodiment of the present invention, both the 5G priority and the 4G priority refer to supporting the 5G/4G/3G/2G multimode network mode, and the 4G priority is preferentially registered regardless of whether there is 5G coverage by removing the 5G network mode, switching to the 4G/3G/2G multimode network mode, and updating to the network side.

ESR (Extended Service Request) signaling is a signaling for instructing electronic devices and network-side devices to fall back from 4G to 2G/3G for CSFB (Circuit Switched Fallback). In the embodiment of the present invention, the purpose of 5G release can be achieved by multiplexing the signaling, and the basic principle is as follows: when receiving an ESR signaling from an electronic device, a network side device usually actively releases a 4G RRC (Radio resource control protocol) connection (which may not be released in a special case, and the processing manner is an timeout mechanism of an ESR timer), instead of under an independent networking, 5G serving as an auxiliary cell anchor is in a connected 4G cell, so that a result of the 4G release is that 5G is naturally released, and a purpose of switching 4G priority can be achieved initially.

SR (Service Request) signaling, an instruction for instructing an electronic device and a network side device to establish 4G RRC connection, where the electronic device sends the SR signaling to the network side device, and may re-enter a 4G connected state from a 4G idle state.

Next, a network switching method provided in an embodiment of the present invention is described.

It should be noted that the method provided by the embodiment of the present invention is applicable to an electronic device, and in practical application, the electronic device may include: smart phones, tablet computers, personal digital assistants, and the like, which are not limited in this embodiment of the present invention.

Fig. 1 is a flowchart of a network handover method according to an embodiment of the present invention, and as shown in fig. 1, the method may include the following steps: step 101, step 102 and step 103, wherein,

in step 101, the temperature, the electric quantity, the currently running service information and the currently working first network access mode of the electronic device are obtained, wherein the first network access mode is one of a 5G network priority access mode and a 4G network priority access mode.

In step 102, whether to switch to a second network access mode is determined according to the temperature, the electric quantity, the currently-operating service information and the first network access mode of the electronic device, wherein the second network access mode is the other one of the 5G network priority access mode and the 4G network priority access mode except the first network access mode.

In the embodiment of the invention, when the first network access mode is a 5G network priority access mode, the second network access mode is a 4G network priority access mode; and when the first network access mode is a 4G network priority access mode, the second network access mode is a 5G network priority access mode.

In an embodiment of the present invention, the step 102 may specifically include the following steps (not shown in the figure): step 1021 and step 1022, wherein,

in step 1021, when the first network access mode is the 5G network priority access mode, if one of the following situations occurs, where the temperature of the electronic device is greater than a preset temperature threshold, the power of the electronic device is lower than a preset power threshold, and a currently running service in the electronic device is a standby service, determining to switch to the 4G network priority access mode;

in the embodiment of the invention, considering that the 5G power consumption is larger than the 4G power consumption, the heat generation is more, and the temperature rise is more obvious when the user continuously uses the service, when the temperature of the electronic equipment exceeds a certain threshold value, for example, exceeds 45 ℃, the user can feel hot, and the CPU performance is also reduced, under the condition, if the electronic equipment is switched to the 4G network priority access mode, the power consumption of the electronic equipment can be reduced.

In the embodiment of the invention, when the remaining power of the electronic device is less than a certain threshold, for example, less than 30%, if the electronic device is switched to the 4G network priority access mode, the duration of the electronic device is prolonged.

In the embodiment of the invention, under the condition that the user does not use the electronic equipment and no background application runs in the electronic equipment, if the electronic equipment is switched to the 4G network priority access mode, the electric quantity of the electronic equipment can be saved.

In step 1022, in the case that the first network access mode is the 4G network priority access mode, if the temperature of the electronic device does not reach the preset temperature threshold, the power of the electronic device is higher than the preset power threshold, and the running service in the electronic device is any one of a file download service, an ultra-clear video playing service, a live broadcast service, a game fighting service, and a preset 5G white list service, it is determined to switch to the 5G network priority access mode.

In the embodiment of the invention, in consideration of the characteristics of low time delay, high speed, high reliability and the like of 5G compared with 4G, when a user downloads a large file through electronic equipment, for example, an apk file is downloaded on an application store through the electronic equipment, or a movie is downloaded through a downloading tool, if the mode is switched to a 5G network priority access mode, the file downloading speed can be increased, and the time consumption for downloading the file can be shortened.

In the embodiment of the invention, when a user watches ultra-clear videos (such as 2K videos or even 4K videos) or live broadcasts through the electronic equipment, the watching using the traditional 4G network is possibly more unsmooth, and if the 5G network has a priority access mode, more excellent user experience can be brought.

In the embodiment of the invention, when the user carries out real-time fighting games through the electronic equipment, the traditional 4G network is likely to suffer from high delay time jamming frequently, and if the traditional 4G network is switched to a 5G network priority access mode, the user experience can be better ensured.

In the embodiment of the invention, a manufacturer or a user of the electronic equipment can set the 5G white list, and flexibly adjust the application/service of the 5G white list according to the actual situation, for example, the user starts a hot spot function, and when the user shares the application/service with other people, the user does not want to consume too fast flow, and can select to delete the application/service from the 5G white list; and if the user is used for connecting a home television to watch the ultra-clear video, the user hopes to obtain better experience, and the user can add the ultra-clear video to the 5G white list.

Therefore, in the embodiment of the invention, 5G and 4G network residence optimization can be carried out aiming at different service scenes, the power consumption is reduced on the premise of not influencing the use experience of a user, and the standby time is prolonged.

In step 103, in case it is determined to switch to the second network access mode, switching from the first network access mode to the second network access mode.

In order to facilitate the overall understanding of the technical solution of the present invention, the description is made with reference to the exemplary diagram shown in fig. 2, as shown in fig. 2: step 201, step 202, step 203, step 204, step 205, step 206, step 207, step 208 and step 209, wherein,

if the determination result is "yes", the process proceeds to step 202.

Step 202: whether the electric quantity is greater than a set threshold value;

Step 204: judging whether the mobile terminal is in standby;

if the determination result is "yes", go to step 203;

if the determination result is "no", step 205 is entered.

Step 205: whether a large file is being downloaded;

if the determination result is "yes", go to step 207;

if the determination result is "no", go to step 206; wherein, a large file package size threshold may be set, for example, 50M, and a large file is set when 50M is exceeded.

Step 206: whether super-definition video/live broadcast is played;

if the determination result is "yes", go to step 207;

if the determination result is "no", step 208 is entered.

Step 207: and switching the 5G priority access mode.

Step 208: whether a real-time battle game is in progress;

if the determination result is "no", go to step 209.

Step 209: whether the service is in a set 5G white list or not;

if the determination result is "yes", go to step 207;

if the determination result is "no", step 203 is entered.

As can be seen from the above embodiments, in this embodiment, the temperature, the electric quantity, the currently operating service information, and the currently operating network access mode of the electronic device may be acquired, and the network access mode may be adjusted according to the acquired content. Compared with the prior art, the embodiment of the invention can perform 5G and 4G network residence optimization according to the temperature, the electric quantity and the service scene of the electronic equipment, reduce the power consumption and prolong the standby time on the premise of not influencing the user experience, thereby improving the user experience.

In an embodiment provided by the present invention, when the first network access mode is a 5G network priority access mode and the second network access mode is a 4G network priority access mode, as shown in fig. 3, fig. 3 is a flowchart of a step of switching from the 5G network priority access mode to the 4G network priority access mode according to the embodiment of the present invention, where the step may include the following steps: step 301, step 302, step 303, step 304 and step 305, wherein,

in step 301, determining whether the electronic device is in a 4G and 5G dual-connection state; if so, go to step 302, otherwise go to step 305.

In the embodiment of the present invention, considering that the electronic device is not necessarily registered in 5G under the condition of 5G priority, for example, a 5G coverage signal is weak (does not satisfy a registration threshold), and the terminal may not register in 5G due to network side access restriction (a 5G system cell sets a flag cellBarred value to barred).

In step 302, if the electronic device is in a 4G and 5G dual-connection state, sending a first ESR signaling to the network side device; the first ESR signaling is used to request the network side device to release the 4G RRC connection between the electronic device and the network side device, so that the electronic device enters a 4G idle state.

In the embodiment of the invention, the electronic equipment requests the network side equipment to release the 4G RRC connection by sending the ESR signaling to the network side equipment, so that the release of the 5G is realized.

In step 303, determining whether the 4G RRC connection between the electronic device and the network side device is released, and if the 4GRRC connection is released, sending a first SR signaling to the network side device; the first SR signaling is used to request the network side device to establish a 4G RRC connection between the electronic device and the network side device, so that the electronic device enters the 4G connection state again from the 4G idle state.

In the embodiment of the present invention, after receiving the ESR signaling from the electronic device, the network side device may immediately issue a Radio Resource Control Connection Release (RRC Release) signaling and carry a 2G/3G redirection frequency point under a normal condition, and after receiving the RRC Release signaling from the network side device, the electronic device enters a 4G idle state. It should be noted that, because the call is not an actual CSFB call, in order to ensure that the 4G anchor can normally reside and does not fall back to the 2G/3G, the electronic device needs to ignore the redirection frequency point and does not perform the redirection step.

Considering that when the electronic device sends the ESR signaling, an ESR timer in the electronic device starts timing, and when the network side device actively releases the 4G RRC connection, the timer stops running, and if the timer is overtime, the electronic device locally releases the RRC connection, that is, the situation is an avoidance measure considering the situation that the network side device does not actively release the 4G RRC connection; before the timer is overtime, the network side equipment is circularly checked whether to actively release the 4G RRC connection. The electronic device locally releases the 4G RRC connection considering that the 3GPP protocol specification does not specify on the 4G network, and the electronic device side can directly notify the network side device to release the RRC release signaling.

Based on the above analysis, correspondingly, in an embodiment of the present invention, the step of determining whether the 4G RRC connection between the electronic device and the network side device is released may specifically include the following steps (not shown in the figure): step 3031 and step 3032, wherein,

in step 3031, if a 4G RRC connection release signaling returned by the network side device is received, it is determined that the 4G RRC connection between the electronic device and the network side device is released;

in step 3032, if the 4G RRC release signaling returned by the network side device is not received within the preset time period, the electronic device is instructed to locally release the 4G RRC connection, and when the electronic device locally releases the 4G RRC connection, it is determined that the 4G RRC connection between the electronic device and the network side device is released.

In the embodiment of the present invention, after it is determined that the 4G RRC connection between the electronic device and the network-side device is released, because the 5G RRC connection between the electronic device and the network-side device is released, the electronic device needs to send an SR signaling to the network-side device to enable the electronic device to reenter the 4G connected state from the 4G idle state.

In step 304, if the electronic device enters the 4G connection state again, it is determined whether the network side device configures a new air interface NR measurement event for the electronic device, and if so, the L2NR measurement is suspended.

In the embodiment of the present invention, when the network side device configures an NR measurement event for the electronic device, the electronic device Mute/suspend L2NR (for short for LTE to NR) measures to implement that the electronic device does not report a 5G measurement report to the network side device, and at this time, the network side device generally does not add a 5G secondary cell, thereby implementing a switch from a 5G network priority access mode to a 4G network priority access mode.

Therefore, in the embodiment of the present invention, ESR signaling is used to implement 4G RRC connection release, and then 5G is correspondingly released, and then SR signaling is initiated to enter a 4G connection state, and then measurement is performed by the electronic device Mute L2NR, so that no NR measurement report is reported to the network side device, and finally 4G priority is implemented. The implementation process does not involve the change of the capability of the electronic equipment, not only can the purpose of fast network switching be realized, but also the performance evaluation of the network side of an operator on the mobile terminal can not be influenced.

In another embodiment provided by the present invention, when the first network access mode is the 4G network priority access mode and the second network access mode is the 5G network priority access mode, as shown in fig. 5, fig. 5 is a flowchart of a step of switching from the 4G network priority access mode to the 5G network priority access mode provided by the embodiment of the present invention, and the step may include the following steps: step 501, step 502, step 503, step 504 and step 505, wherein,

in step 501, determining whether an NR measurement event configured by a network side device remains in an electronic device; if yes, go to step 502, otherwise go to step 503.

In the embodiment of the present invention, as can be seen from the contents in the embodiment shown in fig. 2: one of the processes preferentially implemented by the 4G is MuteL2NR measurement, in which the electronic device does not report an NR measurement report to the network side device.

For this procedure, in the 4G connected state, depending on the implementation of the network side device, there are two possible behaviors: a first behavior, after a certain time (e.g. 3 seconds), the network side device notifies the electronic device to delete the local NR measurement event of the electronic device through reconfiguration signaling; in the second behavior, after the network side device configures the NR measurement event for the electronic device, the electronic device always retains the NR measurement event. In addition, if the electronic device is in the 4G idle state, the NR measurement event configuration is automatically deleted, because the measurement event only exists in the connected state.

In step 502, if the electronic device retains an NR measurement event configured by the network side device, L2NR measurement is started, it is determined whether the measured NR cell signal satisfies a preset reporting condition, and if so, an NR measurement report is reported to the network side device.

In the embodiment of the present invention, when an NR measurement event configured by a network side device is retained in an electronic device, the electronic device starts L2NR measurement to report an NR measurement report to the network side device, and after receiving the NR measurement report from the electronic device, the network side device generally adds a 5G auxiliary cell, thereby implementing 5G priority. For some cases, for example, a non-5G coverage area network or the NR measurement threshold is not reached, the electronic device does not report the NR measurement report, and continuously measures to check whether the reporting condition is met.

In step 503, if no NR measurement event configured by the network side device is reserved in the electronic device, sending a second ESR signaling to the network side device; the second ESR signaling is used to request the network side device to release the 4G RRC connection between the electronic device and the network side device, so that the electronic device enters a 4G idle state.

Considering that in order to implement switching from 4G priority to 5G priority, first, 4G needs to be released, in the embodiment of the present invention, an electronic device requests a network side device to release a 4G RRC connection by sending an ESR signaling to the network side device, so as to implement release of 4G; the ESR signaling is originally a signaling used for guiding the electronic equipment and the network side equipment to fall back from 4G to 2G/3G for CSFB call, and the signaling is multiplexed in the step to ensure that the electronic equipment enters a 4G idle state firstly, so as to provide a premise for initiating a Service Request subsequently: the network side device typically receives this ESR signaling and typically releases the 4G RRC connection on its own.

In step 504, it is determined whether the 4G RRC connection between the electronic device and the network side device is released, and if the 4GRRC connection is released, the second SR signaling is sent to the network side device; the second SR signaling is used to request the network side device to establish a 4G RRC connection between the electronic device and the network side device, so that the electronic device enters the 4G connection state again from the 4G idle state.

In the embodiment of the invention, after receiving the ESR signaling from the electronic device, the network side device immediately issues an RRC release signaling and carries the 2G/3G redirection frequency point under normal conditions, and after receiving the RRC release signaling from the network side device, the electronic device enters the 4G idle state. It should be noted that, because the call is not an actual CSFB call, in order to ensure that the 4G anchor can normally reside and does not fall back to the 2G/3G, the electronic device needs to ignore the redirection frequency point and does not perform the redirection step.

Based on the above analysis, correspondingly, in an embodiment of the present invention, the step of determining whether the 4G RRC connection between the electronic device and the network side device is released may specifically include the following steps (not shown in the figure): step 5041 and step 5042, wherein,

in step 5041, if a 4G RRC connection release signaling returned by the network side device is received, it is determined that the 4G RRC connection between the electronic device and the network side device is released;

in step 5042, if the 4G RRC release signaling returned by the network side device is not received within the preset time period, the electronic device is instructed to locally release the 4G RRC connection, and when the electronic device locally releases the 4G RRC connection, it is determined that the 4G RRC connection between the electronic device and the network side device is released.

In the embodiment of the present invention, after it is determined that the 4G RRC connection between the electronic device and the network-side device is released, because the 4G RRC connection between the electronic device and the network-side device is released, the electronic device needs to send an SR signaling to the network-side device, so that states of the electronic device and the network-side device may be synchronized, and the electronic device enters the 4G connection state from the 4G idle state, so that it is possible for the network-side device to configure an NR measurement event for the electronic device.

In step 505, if the electronic device enters the 4G connection state again, it is determined whether the network side device configures an NR measurement event for the electronic device, and if so, L2NR measurement is started; and determining whether the measured NR cell signal meets a preset reporting condition, and if so, reporting an NR measurement report to network side equipment.

In the embodiment of the present invention, when the network side device configures an NR measurement event for the electronic device, the electronic device starts L2NR measurement to report an NR measurement report to the network side device, and after receiving the NR measurement report from the electronic device, the network side device generally adds a 5G secondary cell, thereby implementing 5G priority. For some cases, for example, a non-5G coverage area network or the NR measurement threshold is not reached, the electronic device does not report the NR measurement report, and continuously measures to check whether the reporting condition is met.

To facilitate an understanding of the 4G-first to 5G-first scheme as a whole, a description is made in conjunction with an example diagram shown in fig. 6, as shown in fig. 6: step 601, step 602, step 603, step 604, step 605, step 606, step 607, step 608, step 609, step 610, step 611 and step 612, wherein,

step 601: the 4G network preferred access mode is switched to the 5G network preferred access mode, and the process proceeds to step 602.

Step 602: whether an NR measurement event remains within the electronic device;

if the determination result is "no", go to step 603;

if the determination result is "yes", the process proceeds to step 609.

Step 603: an Extended Service Request is sent to the network side device, and the step 604 is entered.

Step 604: checking whether the network side equipment actively releases RRC connection;

if the determination result is "no", go to step 606;

if the determination result is "yes", step 605 is entered.

Step 605: and sending a Service Request to the network side device, and entering step 608.

Step 606: checking whether the ESR timer is overtime;

if the result is "no", go to step 604;

if the result is "yes", the process proceeds to step 607.

Step 607: the electronic device locally releases the RRC connection and proceeds to step 605.

Step 608: whether the network side equipment configures an NR measurement event for the electronic equipment or not;

if the determination result is "no", go to step 612;

if the determination result is "yes", the process proceeds to step 609.

Step 609: the L2NR measurement is initiated and step 610 is entered.

Step 610: the measured NR cell signal meets the reporting condition;

if the result is "no", continuously measuring whether the report condition is satisfied.

If the determination result is "yes", the process proceeds to step 611.

Step 611: and reporting an NR measurement report to network side equipment, and adding a 5G cell to the network side equipment.

Step 612: and (6) ending.

It can be seen that, in the embodiment of the present invention, 4G release is implemented by using ESR signaling, and then SR signaling is initiated to enter a 4G connection state, so that it is possible for a network side device to configure an NR measurement event for an electronic device, and then L2NR measurement is started, so that the electronic device can report an NR measurement report to the network side device, and finally 5G priority is implemented. The implementation process does not involve the change of the capability of the electronic equipment, not only can the purpose of fast network switching be realized, but also the performance evaluation of the network side of an operator on the mobile terminal can not be influenced.
