Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to a terminal state determination method and device, a terminal and a network side equipment. BACKGROUND

[0002] In related solutions, a base station can determine the moving state of a terminal in a connected state. One way is for the base station to determine the moving speed through frequency offset estimation. Another way is to determine the moving speed through the change speed of a physical cell identifier (PCI), but it takes a long time (on a high-speed rail, a maximum of 12 physical cells are merged, and it takes at least 60 seconds to pass through a cell, and several cells are needed to determine the change in PCI, which takes 2-10 minutes). However, based on the existing solution, the base station cannot obtain the frequency offset of a terminal in an idle state, and thus cannot determine the moving state of the terminal in the idle state. The terminal needs to be connected to the network and a period of time is needed to determine the moving state. Therefore, one problem is that a low-speed terminal may access a high-speed rail network, and the low-speed terminal will occupy the resources of the network, and the low-speed terminal cannot be processed in a short time. Another problem is that high-speed users and low-speed users are treated equally (cannot be distinguished), which affects the experience of high-speed users. SUMMARY

[0067] In order to make the technical problems solved by the present application, the technical solutions and advantages clearer, the following will be combined with the accompanying drawings and specific embodiments to be described in detail.

[0068] It should be understood that the term "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0069] In various embodiments of the present application, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0070] In addition, the terms "system" and "network" are often used interchangeably in this document.

[0071] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0072] The embodiment of the present application provides a terminal state determination method, which is applied to a terminal, as shown in the figure, and the method comprises the steps that: Figure 1

[0073] ​Step 101: in the case of receiving the message containing the high-speed identifier sent by the first network side device, determining the moving state of the terminal according to the relationship between the first target parameter and the preset threshold value, the first target parameter including at least one of the number of changes of synchronization signal / physical broadcast channel signal block (SSB) index within a target time, the number of SSB switching within the target time, the number of tracking reference signal (TRS) frequency offset flips within the target time, and the number of TRS time-frequency resource changes within the target time, and the moving state including a high-speed moving state or a low-speed moving state.

[0074] In the embodiment of the application, the network side device (such as a base station) corresponding to the high-speed cell carries a high-speed identifier (high speed flag) in a system message, and the high-speed cell can be a high-speed rail dedicated network cell. Through the system message carrying the high-speed identifier, the terminal can determine that it has entered the area covered by the high-speed rail dedicated network and needs to start the process of judging the terminal state.

[0075] The preset threshold value includes a high-speed threshold value and a low-speed threshold value.

[0076] The target time and the preset threshold value can be sent by the first network side device to the terminal.

[0077] The method of the embodiment of the application can quickly determine the moving state of the terminal according to at least one of the number of changes of SSB index within a target time, the number of SSB switching, the number of TRS frequency offset flips, and the number of TRS time-frequency resource changes within the target time, and the relationship between the target parameter and the preset threshold value in the case of receiving the message containing the high-speed identifier sent by the first network side device.

[0078] Optionally, after determining the moving state of the terminal, the method further includes:

[0079] Sending the moving state of the terminal to the first network side device.

[0080] The scheme of the embodiment of the application can quickly determine the moving state of the terminal based on the relationship between the first target parameter and the preset threshold value, and report the moving state to the network side device, so that the network side device can also quickly determine the moving state of the idle-state terminal.

[0081] Optionally, the terminal determines the moving state according to the relationship between the target parameter and the preset threshold value, including:

[0082] In the case of the terminal being in an idle state, determining the moving state of the terminal according to the relationship between the number of changes of SSB index within a target time and the preset threshold value;

[0083] Or, in the case that the terminal is in the connected state, according to a relationship between a first target sub-parameter and a preset threshold, the moving state of the terminal is determined, the first target sub-parameter including a number of SSB switching times within a target time, a number of tracking reference signal (TRS) frequency offset flipping times within the target time, or a number of TRS time-frequency resource changing times within the target time.

[0084] In the embodiment of the application, for a high-speed scenario, the frequency offset presents flipping due to the running mode from near to far, which is different from that of the public network. Whether the terminal is in a high-speed environment is determined by this phenomenon. The frequency offset changes from large to small and then from small to large, which is recorded as one flipping. The frequency offset changes from small to large and then from large to small, which is recorded as one flipping.

[0085] Optionally, the moving state of the terminal is determined according to a relationship between the number of SSB index changes within the target time and the preset threshold, including:

[0086] In the case that the number of SSB index changes within the target time is greater than or equal to a first preset threshold and the physical cell identifier (PCI) changes, the moving state of the terminal is determined to be a high-speed moving state.

[0087] Or, in the case that the number of SSB index changes within the target time is less than or equal to a second preset threshold, the moving state of the terminal is determined to be a low-speed moving state.

[0088] Or, in the case that the number of SSB index changes within the target time is greater than the second preset threshold and less than the first preset threshold, the moving state of the terminal is determined to be an original moving state, the original moving state including the high-speed moving state or the low-speed moving state.

[0089] In the specific embodiment of the application, for a terminal in the idle state, when it enters a high-speed cell through reselection, the network side device corresponding to the high-speed cell will send a system message carrying a high-speed identifier. After the terminal receives the system message, it can determine that the terminal has entered an area covered by the high-speed private network, and then needs to start the judgment of the moving state of the terminal. The terminal in the idle state will periodically search for SSBs, such as Figure 2As shown, the TRS time-frequency resource positions of two directions on the same physical rod on the high-speed rail line are different, the configuration of the SSB is consistent with the TRS, and the SSB index received by the terminal on the high-speed rail will change during movement, such as SSB index1→SSB index2→SSB index1→SSB index2→……SSB index1. The terminal can determine the speed of terminal movement by judging the number of changes of the SSB index. If the number of changes of the SSB index is greater than or equal to N1 (the first preset threshold) in the set period T (the target time described above), and the PCI changes, the terminal judges that it is in a high-speed moving state. If it is less than or equal to M1 (the second preset threshold), it is judged to be in a low-speed moving state. If it is greater than M1 and less than N1, the original moving state remains unchanged. For example, if the terminal is in a high-speed moving state before the moving state is judged, and the number of changes of the SSB index is greater than M1 and less than N1, the moving state of the terminal is determined to be a high-speed moving state. For example, if the terminal is in a low-speed moving state before the moving state is judged, and the number of changes of the SSB index is greater than M1 and less than N1, the moving state of the terminal is determined to be a low-speed moving state.

[0090] Optionally, the determining the moving state of the terminal according to the relationship between the first target sub-parameter and the preset threshold comprises:

[0091] In the case where the first target sub-parameter is greater than or equal to a third preset threshold, the moving state of the terminal is determined to be a high-speed moving state.

[0092] Or, in the case where the first target sub-parameter is less than or equal to a fourth preset threshold, the moving state of the terminal is determined to be a low-speed moving state.

[0093] In the case where the first target sub-parameter is greater than the fourth preset threshold and less than the third preset threshold, the moving state of the terminal is determined to be an original moving state, and the original moving state comprises a high-speed moving state or a low-speed moving state.

[0094] In the embodiment of the present application, for the terminal in the connected state, the moving state can be determined by the beam switching frequency (i.e. the SSB switching number). If the SSB switching number is greater than or equal to N2 (the third preset threshold) within the set target time, the terminal determines that the moving state is high speed; if the SSB switching number is less than or equal to M2 (the fourth preset threshold), the terminal determines that the moving state is low speed; if the SSB switching number is greater than M2 and less than N2, the original moving state is kept unchanged. For example, if the terminal is in the high speed moving state before the moving state is determined, and the SSB switching number is greater than M2 and less than N2, the terminal determines that the moving state is high speed. For example, if the terminal is in the low speed moving state before the moving state is determined, and the SSB switching number is greater than M2 and less than N2, the terminal determines that the moving state is low speed.

[0095] In the embodiment of the present application, for the terminal in the connected state, the moving state can also be determined by the TRS frequency offset flipping number. If the TRS frequency offset flipping number is greater than or equal to N3 (the third preset threshold) within the set target time, the terminal determines that the moving state is high speed; if the TRS frequency offset flipping number is less than or equal to M3 (the fourth preset threshold), the terminal determines that the moving state is low speed; if the TRS frequency offset flipping number is greater than M3 and less than N3, the original moving state is kept unchanged. For example, if the terminal is in the high speed moving state before the moving state is determined, and the TRS frequency offset flipping number is greater than M3 and less than N3, the terminal determines that the moving state is high speed. For example, if the terminal is in the low speed moving state before the moving state is determined, and the TRS frequency offset flipping number is greater than M3 and less than N3, the terminal determines that the moving state is low speed.

[0096] In the embodiment of the present application, for the terminal in the connected state, the moving state can also be determined by the TRS time-frequency resource changing number. The time-frequency resource of the TRS signal is different on different TRPs. If the TRS time-frequency resource changing number is greater than or equal to N4 (the third preset threshold) within the set target time, the terminal determines that the moving state is high speed; if the TRS time-frequency resource changing number is less than or equal to M4 (the fourth preset threshold), the terminal determines that the moving state is low speed; if the TRS time-frequency resource changing number is greater than M4 and less than N4, the original moving state is kept unchanged. For example, if the terminal is in the high speed moving state before the moving state is determined, and the TRS time-frequency resource changing number is greater than M4 and less than N4, the terminal determines that the moving state is high speed. For example, if the terminal is in the low speed moving state before the moving state is determined, and the TRS time-frequency resource changing number is greater than M4 and less than N4, the terminal determines that the moving state is low speed.

[0097] It should be noted that the above N1, N2, N3 and N4 can be the same or different, and the above M1, M2, M3 and M4 can be the same or different.

[0098] Optionally, after sending the moving state of the terminal to the first network side device, the method further comprises:

[0099] After the terminal reselects or switches to the target cell, if the target cell is a high-speed cell, the moving state of the terminal is re-determined and sent to a second network side device, the second network side device being a network side device corresponding to the target cell.

[0100] In the embodiment of the application, after the cell corresponding to the first network side device reselects or switches to a target cell, if a system message carrying a high-speed identifier sent by a second network side device corresponding to the target cell is received, the moving state of the terminal is re-determined and reported to the second network side device.

[0101] In addition, after the terminal reselects or switches to a low-speed cell (which can be a cell other than a high-speed rail dedicated network cell), the detection of the moving state of the terminal is stopped.

[0102] Optionally, the re-determination of the moving state of the terminal comprises:

[0103] If the moving state of the terminal sent to the first network side device is a high-speed moving state, and the moving state of the terminal in the target cell is determined to be a low-speed moving state, the moving state of the terminal is re-determined to be a high-speed moving state.

[0104] Here, the moving state of the terminal in the cell corresponding to the first network side device is a high-speed moving state, and after switching or reselecting to a high-speed cell, if it is judged that the moving state of the terminal in the high-speed cell is a low-speed moving state, the moving state of the terminal is still determined to be a high-speed moving state at this time, indicating that the terminal is still in an area covered by the high-speed rail dedicated network.

[0105] The method of the embodiment of the application can quickly determine the moving state of the terminal according to the relationship between at least one of the number of changes in SSB index within a target time, the number of SSB switches, the number of TRS frequency offset flips, and the number of TRS time-frequency resource changes within a target time and a preset threshold, in the case of receiving a message containing a high-speed identifier sent by a first network side device.

[0106] As shown in Figure 3 The embodiment of the application further provides a terminal state determination method, applied to a network side device, comprising:

[0107] Step 301: determining the moving state of the terminal according to the relationship between a second target parameter and a preset threshold, the second target parameter comprising at least one of the number of TRS frequency offset flips within a target time and the number of TRS time-frequency resource changes within a target time, and the moving state comprising a high-speed moving state or a low-speed moving state.

[0108] The network-side equipment can specifically be a base station.

[0109] Optionally, determining the mobile state of the terminal based on the relationship between the second target parameter and a preset threshold includes:

[0110] If the second target parameter is greater than or equal to the fifth preset threshold, the terminal's movement state is determined to be a high-speed movement state;

[0111] Alternatively, if the second target parameter is less than or equal to the sixth preset threshold, the movement state of the terminal is determined to be a low-speed movement state.

[0112] If the second target parameter is greater than the sixth preset threshold and less than the fifth preset threshold, the movement state of the terminal is determined to be the original movement state, which includes a high-speed movement state or a low-speed movement state.

[0113] It should be noted that the network-side device determines the terminal's mobility status in the same way as the terminal in the connected state, and will not be repeated here.

[0114] According to the method of this invention, the network-side device can quickly determine the mobility status of the terminal based on the relationship between the second target parameter and the preset threshold, which facilitates subsequent differentiation, scheduling or switching of the terminal based on the mobility status.

[0115] like Figure 4 As shown, this embodiment of the invention also provides a terminal status determination device 400, including:

[0116] The first determining module 401 is used to determine the mobility state of the terminal based on the relationship between a first target parameter and a preset threshold when receiving a message containing a high-speed identifier sent by a first network-side device. The first target parameter includes at least one of the following: the number of changes in the Synchronization Signal / Physical Broadcast Channel Signal Block (SSB) index within a target time, the number of SSB switching times within a target time, the number of Tracking Reference Signal (TRS) frequency offset flips within a target time, and the number of TRS time-frequency resource changes within a target time.
