Description

BWP switching method and device of terminal, terminal and storage medium

Technical Field

The present disclosure relates to, but not limited to, the field of communications technologies, and in particular, to a BWP switching method and apparatus for a terminal, and a storage medium.

Background

One of the core requirements of 5 th generation mobile communication technology (5G) networks is enhanced mobile broadband (Enhance Mobile Broadband, eMBB) aimed at meeting the increasing demands of users for high-speed data. To achieve the objective of eMBB, 5G mainly employs an implementation that utilizes a relatively higher frequency band bandwidth. For example, the current range is extended from the highest 20MHz in the 4G era to the 100MHz or 200MHz in the 5G era.

The concept of partial Bandwidth (BWP) was introduced in 5G; for example, 5G may support multiple BWP's, but may only operate at one active BWP at a time; so that 5G can be switched to operate at different BWP.

However, at present, the handover of the terminal between different BWPs is controlled by the scheduling of the network side. The network side cannot know the operation state of the terminal and the like in many times, so that the terminal cannot be scheduled to switch to a proper BWP operation according to the expected requirement of the terminal.

As shown in fig. 2, in one embodiment, an RRC connection is established between a terminal and a network device; the terminal sends terminal auxiliary information (terminal Assistance Information, UAI) to the network device; wherein the UAI indicates that the interior of the terminal is overheated. Here, when detecting the internal overheat, the terminal may report the internal overheat to the base station through a UAI message.

Fig. 3 is a flowchart illustrating a BWP switching method of a terminal according to an exemplary embodiment; as shown in fig. 3, the method is performed by a terminal, and the method includes the steps of:

step S11: detecting the running state of the terminal to determine the bandwidth required by the terminal;

step S12: reporting indication information indicating the bandwidth required by the terminal to network equipment;

step S13: and receiving response information of the network equipment aiming at the indication information, and switching to BWP indicated by the response information.

Here, the terminal may be various mobile terminals or fixed terminals. For example, the terminal may be, but is not limited to being, a server, a computer, a tablet, a mobile handset, a medical device, a wearable device, etc.

Here, the network device may refer to an access network device or a core network device. For example, the access network device may be, but is not limited to being, a base station. For example, the core network device may be, but is not limited to being, various functional entities; such as access and mobility management functions (AMFs).

Here, if the network device is a core network device, step S12 may be: reporting the indication information to a base station, and forwarding the indication information to core network equipment by the base station; the receiving the response information returned by the network device in step S13 may be: the base station receives the response information sent by the core network equipment, and the terminal receives the response information forwarded by the base station.

Here, the indication information is used for the network device to determine response information indicating BWP for the UE to switch.

Here, the operating state may include, but is not limited to including, at least one of: a state of running an Application (APP), a state of network rate, and a dormant state.

In one embodiment, the running APP state includes: running a first class of APP states or running a second class of APP states; wherein the required network rate to run the first class of APPs is greater than the required network rate to run the second class of APPs.

Here, if the first class APP is a speed measurement software class APP, the second class APP may be an online game and/or video class APP. If the first type APP is an online game and/or video type APP, the second type APP can be instant messaging such as WeChat or news website type APP.

In one embodiment, the running APP state includes: running class 1 to class N APP states; wherein the required network rate to operate the i-1 th class of APP states is greater than the required network rate to operate the i-1 th class of APP states; wherein N is an integer greater than 1; and i is an integer less than or equal to N and greater than 1.

Here, the first ratio and the second ratio may be any ratio, and it is only required that the first ratio is greater than the second ratio. For example, the first ratio is 80% and the second ratio is 30%; for another example, the first ratio is 70% and the second ratio is 40%; etc.

The terminal's active BWP is, for example, 40MHz, which corresponds to a network rate of 100Mbit/s; the first ratio is 80% and/or the second ratio is 30%. If the current network rate of the terminal is 90Mbit/s, the ratio of the current network rate of the terminal to the network rate corresponding to the active BWP of the terminal is 90%; the ratio is greater than 80% of the first ratio, the network rate state of the terminal is the first network rate state. Or if the current network rate of the terminal is 20Mbit/s, the ratio of the current network rate of the terminal to the network rate corresponding to the active BWP of the terminal is 20%; the ratio is less than 30% of the second ratio, the network rate state of the terminal is the second network rate state.

Here, the ratio of the current network rate of the terminal to the network rate corresponding to the active BWP of the terminal may also be mapped onto the bandwidth for determination. For example, the first network rate state is: the ratio of the BWP corresponding to the current network rate of the terminal to the active BWP of the terminal is greater than or equal to the first ratio; alternatively, the second network rate state is: the ratio of the BWP corresponding to the current network rate of the terminal to the active BWP of the terminal is less than or equal to the second ratio.

The terminal may be activated with BWP of 40MHZ, a first ratio of 80%, and/or a second ratio of 30% for example. If the current network rate of the terminal is 90Mbit/s and the bandwidth of the running 90Mbit/s is 36MHz, the ratio of BWP corresponding to the current network rate of the terminal to active BWP of the terminal is 90%; the ratio is greater than 80% of the first ratio, the network rate state of the terminal is the first network rate state. Or if the current network rate of the terminal is 20Mbit/s, and the bandwidth for running the 20Mbit/s is 8MHz, the ratio of BWP corresponding to the current network rate of the terminal to active BWP of the terminal is 20%; the ratio is less than 30% of the second ratio, the network rate state of the terminal is the second network rate state.

In another embodiment, the network rate status includes: status of 1 st to nth network rates; wherein the ith network rate is: the ratio of the current network rate of the terminal to the network rate corresponding to the activated BWP of the terminal is greater than or equal to the i ratio; wherein N is an integer greater than 1; the i is an integer less than or equal to N and greater than 1; the j-1 ratio is larger than the j ratio, and j is an integer larger than or equal to i and larger than 1.

In one embodiment, the sleep state may be, but is not limited to being: the off screen state and/or the Application Processor (AP) is in a low power mode. Here, the AP is in a low power mode, which may be, but is not limited to, one of: the terminal is in standby mode and the total power consumption of the operation of the terminal is less than a predetermined power consumption threshold. The application processor refers to an AP; for example, when the mobile phone has dual processors, the method may include: an application processor and a baseband processor; the base station processor is used for taking charge of traditional terminal functions such as mobile access, telephone and the like; and the application processor is responsible for extending functions including, but not limited to, functions of APP such as WeChat, online video, etc.

In one embodiment, the operation state of the terminal may further be: the terminal is in a non-dormant state. Here, the non-sleep state may be, but is not limited to: the bright screen state and/or the application processor is not in a low power mode.

Here, the non-sleep state, i.e., the awake state.

Here, the bandwidth required by the terminal in step S11 is: and the bandwidth is matched with the running state of the terminal. For example, if the running state of the terminal is a first type APP state, the determined bandwidth required by the terminal is a bandwidth matched with the first type APP state. For another example, if the running state of the terminal is the first network rate state, the determined bandwidth required by the terminal is the bandwidth matched with the first network rate state. For another example, if the running state of the terminal is a dormant state, it is determined that the bandwidth required by the terminal is a bandwidth matched with the dormant state.

As shown in fig. 4, in some embodiments, the operating state includes at least one of: a state of running an Application (APP), a state of network rate, and a dormant state;

the step S11 includes:

step S111: and detecting at least one of the state of the running APP of the terminal, the state of the network rate of the terminal and the dormant state of the terminal to determine the bandwidth required by the terminal.

The terminal detects the operation state of the terminal; if the terminal determines the running state of the terminal, determining the bandwidth required by the terminal and matched with the running state based on the running state. For example, if the running state of the terminal is the first type APP state, the determined bandwidth required by the terminal is greater than or equal to the first predetermined bandwidth; the first preset bandwidth is the bandwidth corresponding to the network rate required by the operation of the first type of APP.

Thus, in the embodiment of the present disclosure, by detecting one or more operation states such as the state of the APP, the state of the network rate, and the sleep state, which are operated by the terminal, the bandwidth required by the operation state operated by the terminal may be accurately determined.

In one embodiment, the indication information includes: the first indication information or the second indication information; wherein, the first indication information is used for the network equipment to determine response information of the first BWP for indicating the terminal to switch; the second indication information is used for the network equipment to determine response information of the second BWP indicating the terminal to be switched.

In another embodiment, the indication information includes: 1 st to nth indication information; wherein, the i-th indication information is used for the network equipment to determine the response information of the i-th BWP for indicating the terminal to switch; wherein N is an integer greater than 1; and i is an integer less than or equal to N and greater than 1.

Thus, in the embodiment of the present disclosure, the indication information indicating the different bandwidths may be determined corresponding to the multiple different bandwidths determined by the terminal; the indication information may be used for the network device to determine a different BWP to which the terminal is handed over.

In one embodiment, the BWP indicated by the response information includes: a first BWP or a second BWP; wherein the first BWP is larger than the second BWP.

In another embodiment, the BWP referred to by the response information includes: ith to nth BWP; wherein, the i-1 BWP is larger than the i BWP; wherein N is an integer greater than 1; and i is an integer less than or equal to N and greater than 1.

Thus, in the embodiment of the present disclosure, different response information may be determined for indication information of bandwidths required by different indication terminals; the response information indicates that the terminal can switch to a different BWP.

Here, the bandwidth supported by the terminal is divided into one or more BWP; the bandwidth of each BWP may be the same or different in size. In some embodiments of the present disclosure, the plurality is 2 or more. Here, the bandwidth supported by the terminal can be considered as: full bandwidth.

Here, the BWP supported by the terminal may be one or more. Here, the BWP currently activated by the terminal may be one.

In the embodiment of the present disclosure, the terminal may report the indication information to the network device according to the bandwidth requirement of the terminal, so that the network device configures the BWP with the appropriate bandwidth for the terminal, and further, the terminal currently activates the BWP to switch to the BWP with the appropriate bandwidth. For example, if the terminal is operating in a state with a relatively large bandwidth requirement, the BWP currently activated by the terminal may be switched to the BWP with a relatively large bandwidth, so as to meet the bandwidth requirement of the terminal operation; also, if the terminal is operating in a state where the bandwidth requirement is relatively small, the BWP currently activated by the terminal may be caused to switch to the BWP with the relatively small bandwidth, so that the power consumption of the terminal may be reduced, etc.

The BWP switching manner of the terminal provided in the embodiments of the present disclosure, compared with a manner in which the terminal is scheduled to activate BWP to switch to configured BWP through the network device, may enable the terminal to activate BWP to switch to appropriate BWP according to the actual running state of the terminal.

For example, when the terminal performs network speed measurement, the network device may have relatively small bandwidth for scheduling the terminal due to the fact that the network device cannot know the state of the terminal in real time, so that the terminal cannot be switched to the full bandwidth or relatively large bandwidth for downloading or uploading, and the actual throughput rate of the terminal is affected. The embodiment of the disclosure can enable the network device to configure the full bandwidth or the relatively large bandwidth for the terminal through reporting the indication information of the full bandwidth or the relatively large bandwidth required by the terminal, so that the terminal can be switched to the full bandwidth or the relatively large bandwidth for downloading or uploading; therefore, the occurrence of the clamping situations of improving the actual throughput of the terminal, reducing the network speed measurement and the like of the terminal is reduced.

For another example, when the terminal performs small data packet transceiving, the network device may cause relatively large bandwidth to be scheduled to the terminal due to the fact that the state of the terminal cannot be known in real time, so that the terminal works under relatively large or full bandwidth; this results in a higher power consumption of the terminal than expected. The embodiment of the disclosure can enable the network equipment to configure the terminal with the relatively smaller bandwidth through reporting the indication information of the relatively smaller bandwidth required by the terminal, so that the terminal can be switched to the relatively smaller bandwidth to work; this can reduce the power consumption of the terminal.

In some embodiments, the step S12 includes:

and reporting terminal auxiliary information (UAI) carrying the indication information to the network equipment.

Here, the indication information is carried in a predetermined bit of the UAI. The predetermined bit may be specified by a protocol or may be negotiated with the network device by the terminal. The predetermined bit may be a reserved bit in the UAI or a newly added bit in the UAI. The predetermined bits may be one or more bits.

In the embodiment of the disclosure, the indication information can be reported to the network equipment through the UAI; therefore, on one hand, the utilization rate of UAI information can be improved; on the other hand, one UAI can complete two functions of auxiliary information reporting and indication information reporting, so that signaling interaction is reduced, power consumption of a terminal and network equipment is reduced, and the like.

Of course, in other embodiments, the indication information may be reported by other messages or signaling, which is not limited herein.

As shown in fig. 5, in some embodiments, the step S111 includes at least one of:

step S111a: if the state of the running APP of the terminal is detected to be the state of the running APP of the first class, determining that the bandwidth required by the terminal is larger than a first preset bandwidth;

step S111b: if the network rate state of the terminal is detected to be a first network rate state, determining that the bandwidth required by the terminal is larger than the first preset bandwidth; wherein the first network rate state is: the ratio of the current network rate of the terminal to the network rate corresponding to the activated BWP of the terminal is greater than or equal to the first ratio;

step S111c: if the terminal is detected not to be in the dormant state, determining that the bandwidth required by the terminal is larger than the first preset bandwidth; wherein the sleep state comprises: the off-screen state and/or the application processor is in a low power mode.

Referring again to fig. 5, the step S12 includes:

step S121: reporting the first indication information indicating that the bandwidth required by the terminal is greater than the first preset bandwidth to network equipment; wherein the first indication information is used for a network device to determine response information of the first BWP for indicating the terminal handover;

the switching to the BWP indicated by the response information in step S13 includes:

step S131: and switching to the first BWP indicated by the response information.

In one embodiment, the first predetermined bandwidth is less than the bandwidth of the first BWP. Here, it is determined in this step S111a, step S111b, and/or step S111c that the bandwidth required by the terminal is greater than the first predetermined bandwidth and less than or equal to the bandwidth of the first BWP.

Here, the terminal is not in the sleep state in step S111c, i.e., the terminal is in the non-sleep state.

In one embodiment, the bandwidth of the first BWP may be a full bandwidth supported by the terminal.

In another embodiment, the bandwidth of the first BWP is greater than a predetermined bandwidth threshold.

In yet another embodiment, the bandwidth of the first BWP is a bandwidth corresponding to a first type APP state, a first network rate state, or a non-dormant state.

Here, the first indication information may be indicated with a predetermined bit. For example, it may be indicated by "01". Here, for the different first indication information, different bits may be used for indication.

The method includes the steps that if the terminal detects that a foreground application program of the terminal has APP starting with relatively large network speed, namely APP starting of a first type, the terminal determines that the bandwidth required by the terminal is larger than a first preset bandwidth; the terminal determines first indication information indicating that the bandwidth required by the terminal is larger than a first preset bandwidth, and reports the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

If the terminal detects that the current network rate of the terminal is greater than or equal to 80% of the network rate corresponding to the current total bandwidth of the terminal, determining that the bandwidth required by the terminal is greater than the first preset bandwidth; the terminal determines first indication information indicating that the bandwidth required by the terminal is larger than a first preset bandwidth, and reports the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

The terminal determines that the bandwidth required by the terminal is greater than a first preset bandwidth if the terminal is detected to be in a bright screen state or an application processor of the terminal is not in a low power consumption mode; the terminal determines first indication information indicating that the bandwidth required by the terminal is larger than a first preset bandwidth, and reports the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

Thus, in the embodiment of the present disclosure, the terminal may determine, based on a plurality of ways of detecting the operation state of the terminal, that the bandwidth required by the terminal is greater than the first predetermined bandwidth; and determining that the first indication information corresponding to the bandwidth required by the terminal is greater than the first preset bandwidth and reporting the first indication information to the network equipment so that the network equipment configures proper BWP for the terminal to switch.

In some embodiments, reporting, in step S121, first indication information indicating that the bandwidth required by the terminal is greater than the first predetermined bandwidth to the network device includes:

The method includes the steps that if the terminal detects that a foreground application program of the terminal has APP starting with relatively large network speed, namely APP starting of a first type, the terminal determines that the bandwidth required by the terminal is larger than a first preset bandwidth; if the terminal determines that the bandwidth of the current activated BWP of the terminal is smaller than a first preset bandwidth, determining first indication information for indicating that the bandwidth required by the terminal is larger than the first preset bandwidth, and reporting the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

For example, if the terminal detects the current network rate to be greater than or equal to 80% of the network rate corresponding to the current total bandwidth of the terminal, determining that the bandwidth required by the terminal is greater than the first predetermined bandwidth; if the terminal determines that the bandwidth of the current activated BWP of the terminal is smaller than a first preset bandwidth, determining first indication information for indicating that the bandwidth required by the terminal is larger than the first preset bandwidth, and reporting the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

If the terminal detects that the terminal is in a bright screen state or the application processor of the terminal is not in a low power consumption mode, determining that the bandwidth required by the terminal is larger than a first preset bandwidth; if the terminal determines that the bandwidth of the current activated BWP of the terminal is smaller than a first preset bandwidth, determining first indication information for indicating that the bandwidth required by the terminal is larger than the first preset bandwidth, and reporting the first indication information to the network equipment; the terminal receives response information returned by the network device based on the first indication information and switches to the first BWP indicated by the response information.

In this way, in the embodiment of the present disclosure, when it is determined that the bandwidth required by the terminal is greater than the first predetermined bandwidth by various ways of detecting the operation state of the terminal, and the current active BWP of the terminal is less than the first predetermined bandwidth, the first indication information corresponding to the indication that the bandwidth required by the terminal is greater than the first predetermined bandwidth is reported to the network device. In this way, the embodiment of the disclosure can report the indication information of the required relatively large bandwidth only when the terminal is insufficient in the current active BWP; therefore, the indication information can be reported at a proper time; on one hand, the terminal can be switched to the proper BWP, and on the other hand, the power consumption caused by continuously reporting the first indication information is reduced.

As shown in fig. 6, in some embodiments, the step S111 includes at least one of:

step S111d: if the state of the running APP of the terminal is detected to be the second class of APP running state, determining that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth; wherein the network rate required to operate the second class of APP is less than the network rate required to operate the first class of APP;

In one embodiment, the second predetermined bandwidth is smaller than a bandwidth of the second BWP.

In one embodiment, the bandwidth of the second BWP is less than the first predetermined bandwidth.

In one embodiment, the bandwidth of the second BWP is a bandwidth corresponding to the second class APP state, the second network rate state, or the dormant state.

Here, the second indication information may be indicated with a predetermined bit. For example, it may be indicated with "00". Here, for the different second indication information, different bits may be used for indication.

The terminal determines that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth if detecting that the foreground application of the terminal has APP start with relatively smaller network speed, namely, second class APP start; the terminal determines second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reports the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

If the terminal detects that the current network rate of the terminal is less than or equal to 30% of the network rate corresponding to the current total bandwidth of the terminal, determining that the bandwidth required by the terminal is less than or equal to a second preset bandwidth; the terminal determines second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reports the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

The terminal determines that the bandwidth required by the terminal is smaller than or equal to the second preset bandwidth if detecting that the terminal is in the off-screen state or the application processor of the terminal is in the low-power consumption mode; the terminal determines second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reports the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

Thus, in the embodiment of the present disclosure, the terminal may determine, based on a plurality of ways of detecting the operation state of the terminal, that the bandwidth required by the terminal is less than or equal to the first predetermined bandwidth; and determining that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reporting second indication information corresponding to the bandwidth required by the terminal to the network equipment, so that the network equipment configures proper BWP for the terminal to switch.

In some embodiments, the step S122 of reporting the second indication information indicating that the bandwidth required by the terminal is less than or equal to the second predetermined bandwidth to the network device includes:

The terminal determines that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth if detecting that the foreground application of the terminal has APP start with relatively smaller network speed, namely, second class APP start; if the terminal determines that the bandwidth of the current activated BWP of the terminal is larger than or equal to a first preset bandwidth, determining second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reporting the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

If the terminal detects that the current network rate of the terminal is less than or equal to 30% of the network rate corresponding to the current total bandwidth of the terminal, determining that the bandwidth required by the terminal is less than or equal to a second preset bandwidth; if the terminal determines that the bandwidth of the current activated BWP of the terminal is larger than or equal to a first preset bandwidth, determining second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reporting the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

The terminal determines that the bandwidth required by the terminal is smaller than or equal to the second preset bandwidth if detecting that the terminal is in the off-screen state or the application processor of the terminal is in the low-power consumption mode; if the terminal determines that the bandwidth of the current activated BWP of the terminal is larger than or equal to a first preset bandwidth, determining second indication information indicating that the bandwidth required by the terminal is smaller than or equal to a second preset bandwidth, and reporting the second indication information to the network equipment; the terminal receives response information returned by the network device based on the second indication information and switches to the second BWP indicated by the response information.

Thus, in the embodiment of the present disclosure, when it is determined that the bandwidth required by the terminal is less than or equal to the second predetermined bandwidth by detecting the operation state of the terminal in various manners, and the current active BWP of the terminal is greater than or equal to the first predetermined bandwidth, the second indication information corresponding to the indication that the bandwidth required by the terminal is less than or equal to the first predetermined bandwidth is reported to the network device. In this way, the embodiment of the disclosure can report the indication information of the required relatively small bandwidth only when the bandwidth of the current active BWP of the terminal is relatively large; therefore, the indication information can be reported at a proper time; on one hand, the terminal can be switched to the proper BWP, and on the other hand, the power consumption caused by continuously reporting the first indication information is reduced.
