Description

Technical Field

[0001] The present invention relates to the field of mobile communication technologies, and in particular to a 5G network dynamic configuration method, device, and computer-readable storage medium. Background Art

[0002] In the existing technology, with the continuous development of mobile communication technology, 5G network has brought a brand new experience to people.

[0003] Currently, the existing operators' network deployment of 5G networks still does not have the extensive coverage of LTE networks. Therefore, for terminals that support SA, it is necessary to quickly access the 5G network to improve the user experience brought by 5G network technology. Based on this, the SIB24 broadcast is defined in the 3GPP specification to implement the reselection operation of the 4G network and the 5G network.

[0004] However, in real-world scenarios, since a large number of old terminals do not support SIB24 broadcasts, they may be disconnected from the network or even restarted. At this point, network rollback or upgrading of core routers is necessary. This means that after the terminal enters the idle state, it is difficult to quickly fall back to the 5G network. At the same time, some terminals find it difficult to switch back to the 5G network after switching to the 4G network, which prevents the high-speed advantage of the 5G network from being fully utilized.

[0005] Therefore, how to enable a terminal in a 4G network to quickly return to a 5G network in an idle or connected state has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the above technical defects in the prior art, the present invention proposes a 5G network dynamic configuration method, which includes:

[0007] When the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell exists in the preset NR reachable cell list. If so, a background search is initiated, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated with the NR cell;

[0008] When the terminal is in a connected state and in an LTE cell, it determines whether the throughput of the current network within a preset time is less than a preset threshold. If so, it detects whether the current network releases wireless resource control. If so, it redirects to the 5G cell according to the network. If not, the terminal releases wireless resource control by itself and enters the idle state.

[0009] Optionally, the method further comprises:

[0010] Presetting the NR reachable cell list and the neutral cell list in the terminal;

[0011] When the terminal registers the network, it searches for neighboring cells within a preset search period, and adds neighboring cells belonging to the NR cell to the NR reachable cell list, and adds neighboring cells that do not belong to the NR cell to the neutral cell list.

[0012] Optionally, the method further comprises:

[0013] Presetting a NR unreachable cell list in the terminal;

[0014] The first number of unsearched times when searching for the NR cells in the NR reachable cell list is recorded according to the search cycle, and when the first number of unsearched times of the NR cell is greater than a first quantity threshold, the NR cell is moved from the NR reachable cell list to the NR unreachable cell list.

[0015] Optionally, the method further comprises:

[0016] When the NR cell is added to the NR unreachable cell list, starting a timer;

[0017] When the timer times out, the NR cell is moved from the NR unreachable cell list to the neutral cell list.

[0018] Optionally, after the terminal releases radio resource control by itself and enters the idle state, the method includes:

[0019] When the terminal is in an idle state and in an LTE cell, it is determined again whether the LTE cell exists in the preset NR reachable cell list;

[0020] If it exists, the background search is initiated again, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated with the NR cell.

[0021] The present invention also proposes a 5G network dynamic configuration device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the computer program is executed by the processor, the following is achieved:

[0022] When the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell exists in the preset NR reachable cell list. If so, a background search is initiated, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated with the NR cell;

[0023] When the terminal is in a connected state and in an LTE cell, it determines whether the throughput of the current network within a preset time is less than a preset threshold. If so, it detects whether the current network releases wireless resource control. If so, it redirects to the 5G cell according to the network. If not, the terminal releases wireless resource control by itself and enters the idle state.

[0024] Optionally, when the computer program is executed by the processor, it implements:

[0025] Presetting the NR reachable cell list and the neutral cell list in the terminal;

[0026] When the terminal registers the network, it searches for neighboring cells within a preset search period, and adds neighboring cells belonging to the NR cell to the NR reachable cell list, and adds neighboring cells that do not belong to the NR cell to the neutral cell list.

[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0050] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0051] Figure 1 This embodiment proposes a 5G network dynamic configuration method, the method comprising:

[0052] S1. When the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell exists in the preset NR reachable cell list. If so, a background search is initiated, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated with the NR cell;

[0053] S2. When the terminal is in a connected state and in an LTE cell, determine whether the throughput of the current network within a preset time is less than a preset threshold. If so, detect whether the current network releases wireless resource control. If so, redirect to the 5G cell according to the network. If not, the terminal releases wireless resource control by itself and enters the idle state.

[0054] Optionally, in this embodiment, a solution for quickly returning to 5G on the terminal side is provided, so that the terminal can quickly return to 5G regardless of whether it is in an idle state or a connected state, thereby ensuring the 5G rate and improving the user experience. Figure 6 and Figure 7:First, when the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell is a cell in the NR reachable cell list. If so, a background search is initiated to search for the NR cell in its cell list. If found, registration is initiated to quickly return to the 5G cell; then, when the terminal is in a connected state and in an LTE cell, it is determined whether the Thput throughput is less than the threshold Threshold within a continuous T time. If so, it is further determined whether the network releases RRC (Radio Resource Control). If the network releases, it is redirected to the 5G cell according to the network. If the network does not release RRC, the terminal actively releases RRC and the terminal enters an idle state; finally, the above-mentioned idle state processing solution is used again to enable the terminal to quickly enter the 5G cell and initiate networking again.

[0055] The beneficial effect of this embodiment is that when the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell exists in the preset NR reachable cell list. If so, a background search is initiated, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated to the NR cell; when the terminal is in a connected state and in an LTE cell, it is determined whether the throughput of the current network within a preset time is less than a preset threshold. If less than, it is detected whether the current network releases wireless resource control. If released, it is redirected to the 5G cell according to the network. If not released, the terminal releases wireless resource control by itself and enters the idle state. An efficient and convenient 5G network dynamic configuration solution is implemented, so that the terminal can quickly return to the 5G network whether in an idle state or a connected state, which greatly improves the adaptability of old terminals to 5G networks and the user's network experience.

[0056] Figure 2 It is a second flow chart of the 5G network dynamic configuration method of the present invention. Based on the above embodiment, the method also includes:

[0057] S01. Presetting the NR reachable cell list and the neutral cell list in the terminal;

[0058] S02. When the terminal registers the network, it searches for neighboring cells within a preset search period, and adds neighboring cells belonging to the NR cell to the NR reachable cell list, and adds neighboring cells that do not belong to the NR cell to the neutral cell list.

[0059] Figure 3 It is a third flow chart of the 5G network dynamic configuration method of the present invention. Based on the above embodiment, the method further includes:

[0060] S03, presetting a list of NR unreachable cells in the terminal;

[0061] S04. Record the first number of unsearched times when searching for NR cells in the NR reachable cell list according to the search cycle, and when the first number of unsearched times of the NR cell is greater than a first quantity threshold, move the NR cell from the NR reachable cell list to the NR unreachable cell list.

[0062] Figure 4 It is a fourth flow chart of the 5G network dynamic configuration method of the present invention. Based on the above embodiment, the method also includes:

[0063] S05. When the NR cell is added to the NR unreachable cell list, start a timer;

[0064] S06. When the timer times out, the NR cell is moved from the NR unreachable cell list to the neutral cell list.

[0065] Optionally, in this embodiment, please refer to Figure 8 After the terminal registers with the network, the background periodic search timer Timer_back is turned on. During the background search, if an NR cell is found in the surrounding neighboring area, the cell is added to the NR reachable cell list. If not found, the cell is added to the neutral cell list. After being added to the NR reachable cell list, it will not stay in the cell all the time. If the NR cell is not found during each periodic search, the number of unsearched times of the cell is N1+1. When N1 is greater than the threshold value N1max, the cell is added to the NR unreachable cell list. Similarly, for the cells in the neutral cell list, if the NR cell is not found during each periodic search, the number of unsearched times of the cell is N2+1. When N2 is greater than the threshold value N1max, the cell is added to the NR unreachable cell list. Similarly, the cells in the NR unreachable cell list are not static. After each cell is added to the list, a timer will be started. When the timer of a cell in the list times out, the cell automatically returns to the neutral cell list.

[0066] Optionally, in this embodiment, please refer to Fig. 9 The NR reachable list stores N cells, each of which contains the cell id, LTE earfcn List and its corresponding neighboring NR list. It also stores the number of times N1 that the cell has not been found in the periodic search.

[0067] Optionally, in this embodiment, please refer to Fig.10The NR unreachable list stores N cells. Each cell contains the cell id, LTE earfcn List and its corresponding neighboring NR list. It also stores the timer for entering the cell. When the timer times out, the cell needs to be released.

[0068] Optionally, in this embodiment, please refer to Fig.11 The neutral cell list stores N cells, each of which contains the cell id, LTE earfcn List, and the number of times N2 that the cell has not been found in the periodic search. When N2 is greater than N2max within the periodic search range, the cell is moved to the NR unreachable list.

[0069] Figure 5 It is a fifth flow chart of the 5G network dynamic configuration method of the present invention. Based on the above embodiment, after the terminal releases the wireless resource control by itself and enters the idle state, the method includes:

[0070] S31. When the terminal is in an idle state and in an LTE cell, it is determined again whether the LTE cell exists in a preset NR reachable cell list;

[0071] S32. If it exists, initiate background search again and search for the NR cell in the NR reachable cell list. If found, initiate registration with the NR cell.

[0072] Optionally, in this embodiment, when the terminal is in an idle state, if the terminal is in a 4G cell, it is determined whether the current cell is a cell in the NR reachable list. If so, the NR cell is searched according to the frequency of the NR in the list. When the NR cell is found, the registration of the NR cell is immediately initiated, and the NR cell is quickly returned to the NR cell without reselecting to 5G according to the configuration of SIB24; if the cell does not find the NR cell, the status update of N1 in the list is initiated, and reference is made to Figure 6 The process shown in FIG. 1 updates the NR unreachable cell list, and if the current cell is not in the NR cell reachable list, a neutral cell search is initiated, refer to FIG. Figure 6 The process shown determines whether to update the neutral cell status.

[0073] Optionally, in this embodiment, when the terminal is in the connect state, if the terminal is in 4G, in particular, if it is EPSFB (EPS FB means that when 5G does not have VoNR conditions, the voice service falls back from 5G to 4G, relying on VoLTE to ensure the continuity of the voice service) to 4G, it is necessary to return to 5G as soon as possible. If the network does not trigger the switching process, the terminal side needs to autonomously return to NR. At this time, it is determined whether the Thput throughput is less than the threshold Threshold within the continuous T time. If it is less than, monitor whether the network releases RRC. If the network releases, redirect to the 5G cell according to the network; if the network does not release RRC, the terminal actively releases RRC and the terminal enters the idle state; finally, the terminal quickly enters the 5G cell according to the idle state plan and initiates networking.

[0074] Based on the above embodiments, the present invention further proposes a 5G network dynamic configuration device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the computer program is executed by the processor, the following is achieved:

[0075] When the terminal is in an idle state and in an LTE cell, it is determined whether the LTE cell exists in the preset NR reachable cell list. If so, a background search is initiated, and the NR cell in the NR reachable cell list is searched. If found, registration is initiated with the NR cell;

[0076] When the terminal is in a connected state and in an LTE cell, it determines whether the throughput of the current network within a preset time is less than a preset threshold. If so, it detects whether the current network releases wireless resource control. If so, it redirects to the 5G cell according to the network. If not, the terminal releases wireless resource control by itself and enters the idle state.

[0077] Optionally, when the computer program is executed by the processor, it implements:
