[0055]In order to make the objects, technical solutions, and advantages of the present application, the technical solutions in the present application embodiment will be clearly described, and the described embodiments will be described in conjunction with the drawings in the present application embodiment. It is merely an embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, those of ordinary skill in the art without all other embodiments obtained by creative labor, including, but not limited to, a combination of a plurality of embodiments belongs to the scope of the present application.

[0056]The description and claims of the present application and the terms "first", "second", "third" "third" "" fourth ", etc. in the above drawings are used to distinguish similar objects without Describe specific order or prior order. It is to be understood that the data such as use can be interchanged in place so that the embodiments of the present application described herein can be implemented, for example, in the order other than those illustrated or described herein. Moreover, the terms "including" and "having" and any variations are intended to cover non-rowing, such as process, methods, systems, products, or equipment that contain a series of steps or units, including a series of steps or units, are not necessarily limited to clearly These steps or units may include other steps or units that are not clearly listed or for these processes, methods, products, or equipment.

[0057]Mobile communication technology has entered 5G era, with the rapid update of mobile communication technology, in order to speed up the new generation of wireless communication networks, let the new generation of wireless communication technology enters the commercial phase as soon as possible, many operations Solutions to jointly build a new generation of network base stations, that is, in the focus of wireless communication coverage, share some or all new generation network base stations, to serve many operators at the same time, which can greatly accelerate new operators A generation of networks fully covered, and can broaden the area available bandwidth.

[0058]Due to the multiplicate communication technology, the existing solutions are expanded on the basis of the communication base station of the existing mature technology in order to improve the utilization rate of resources and speeding up the new generation of technology. A new generation of base stations are gradually deployed, so that new technologies can be accepted and reduce switching costs and time.

[0059]However, since different carriers are generally communicated with different frequency bands, this has caused the user terminal to share the base station of the multi-operator. When switching the communication cell, it is necessary to switch, but due to the user terminal and / / Or the base station has not achieved direct foreign exchange between the new generation of communication technologies, it also achieves direct foreign exchange between the communication cells of the new generation of communication technology, which leads to the user terminals must achieve foreign exchanges through the previous generation of communication technology.

[0060]For example, the current 5G base station and the user terminal do not support NR (New Radio, new air) abruptly switching under the architecture of NSA (Non-Standalone, non-stand-alone network), but different operators' operational bands are different. However, the cell corresponding to the shared base station of different operators is unconventional, so that when the user terminal is located on the edge of the multi-operator shared base station signal coverage, the user terminal needs to switch when the cell corresponding to different operators, only It is possible to rely on the unusual switching of the 4G core network corresponding to the two switching cells. Since the existing 4G core network has been capable of implementing the user terminal to switch between 4G communication cells between the non-communication between the base station. Therefore, the user terminal is switched in the existing 5G communication mode. To perform different operational business 5G cell switching, it is necessary to switch to another operator corresponding to the 5G target switching cell by 4G communication mode. Add 5G auxiliary carrier, access 5G target switching cell.

[0061]However, the existing cell handover mode is complex, time-consuming, resulting in technical issues that may occur when 5G users may occur during cell switching.

[0062]A communication cell switching method is proposed for solving the above problems, which will be described below with reference to the specific embodiments and the drawings.

[0063]In order to facilitate understanding, the professional terms involved in the present application will be described below.

[0064]SSB (Synchronization Signal and PBCH block, a synchronization signal and a physical broadcast channel block): It consists of a primary synchronization signal (Primary Synchronization Signals, referred to as PSS), a secondary synchronization signal (SecondarySynchronization Signals, referred SSS), PBCH (Physical Broadcast Channel, the Physical Broadcast The channel is integrated with three parts. In the 5G NR, the concept of SSB appears, and it is simple to consist of the original primary synchronization sequence, a secondary step sequence, a physical broadcast channel, and demodulation reference signal, which is mainly used for downlink synchronization.

[0065]GSCN (Global Synchronization Channel Number, global synchronization channel number): When the terminal is set, when the cell search is turned on, it can only detect the SSB signal according to the carrier and the frequency band supported by the terminal, perform downward time-frequency synchronization. Since the particle size of the global frequency raster results in a large range of NR-ARFCN (NR ABSOLUTE RADIO FREQUENCHANNEL NUMBER Absolute Frequency Channel No.), if the blind inspection is performed directly according to the global frequency grid, it will be relatively large. In order to effectively reduce the synchronous delay of this process, 3GPP specializes in the concept of synchronous raster, and limits the search range via GSCN.

[0066]PCI (Physical Cell Identifier, Physical Community Identification) LTE Terminal The wireless signal of different cells is distinguished. The LTE system provides 504 PCI, and the 128 disturbance concept of the TD-SCDMA system is similar, and the network management configuration is a number between 0 to 503 in the cell. The LTE cell search process is retrieved by retrieving the main sync sequence (PSS, there are three possibilities), the secondary step (SSS, a total of 168 possibilities), and the two combine to determine the specific cell ID.

[0067]PRACH (Physical Random Access Channel), is the access channel when the user terminal UE (user equipmen) is started, and the UE receives the FPACH (Fast Physical AccessChannel, the fast physical access channel) response message The RRC (Radio Resource Control, Radio Resource Control) connection request message will be transmitted according to the information indicated by Node B, and the RRC connection is created.

[0068]figure 1 The user terminal provided for the user terminal shares the scene of the cell boundary position of the multistage of the 5G base station in the multistrand. Such asfigure 1 The 5G base station and cell 111, the 5G base station and the cell 111, the second operator undertake and manage the 5G base station and the cell 112. When the user terminal moves from the boundary point A of the cell 111 to the boundary point B of the cell 112, switching of the 5G communication cell is required.

[0069]figure 2 A schematic diagram of the 5G cell switching process between different operators in the prior art. Such asfigure 2 As shown, after the user terminal sends a handover request, the first operational merchant station first deletes the first 5G carrier of the user terminal, the first 5G community, the first 5G cell, and access the user to the 4G communication mode, the first The operator base station corresponds to the first shared anchor, the first 4G frequency point under the long-term evolution technology LTE of 4G, and then connects the user terminal to the base station corresponding to the second operator's base station. 4G LTE The two shared anchor, so that the switch between two base stations is completed, and then the second operator base station connects the user terminal to the target switching cell corresponding to the second 5G carrier, thereby completing the user endfigure 1 The resolved cell 111 to the cell 112. It can be seen that the 5G cell switching process under the NSA network architecture is very complicated, and it takes longer.

[0070]image 3 A flow chart of a communication cell switching method provided herein. Such asimage 3 As shown, the communication cell switching method provided in the present application embodiment, the specific steps include:

[0071]S301, the cell switch request from the first cell to the second cell is acquired.

[0072]In this step, the first cell and the second community are communication cells in the first communication mode, the first base station corresponding to the first community, is the first operator construction management and sharing with the second business business. The base station used, the second cell corresponding to the second base station is the second operator to build a base station that is shared with the first operator, the first base station and the second base station using the same frequency. The anchor is wireless communication.

[0073]Specifically, in the present embodiment, the first communication mode is 5G communication mode. The first cell and the second community are located on the edge of the shared area of ​​the corresponding carrier.

[0074]S302, determine the shared anchor point corresponding to the second cell according to the cell switching request.

[0075]In this step, the shared anchor is a communication anchor in the second communication mode, the communication characteristics of the first communication mode superior to the second communication mode. In the present embodiment, the second communication mode is 4G communication mode.

[0076]Specifically, the shared anchor is a communication frequency in 4G communication mode, the first base station and the second base station can share this frequency of wireless communication, ie the two base stations implements the same frequency operation. Thus, when the 5G cell switching is performed, the switching process of the 4G non-versus anchor point can be omitted, and the switching speed is accelerated.

[0077]S303, connect the client to the second cell based on the shared anchor and the cell switching request.

[0078]In this step, since 4G shared anchor is not changed, the first base station and the second base station are operated as the same as the same frequency, so that the exchange is replaced by the exchange, only to switch on the basis of 4G shared anchor points. The corresponding 5G auxiliary carrier can connect the user to the second cell from the first cell.

[0079]The communication cell switching method provided in this embodiment, by acquiring a cell handover request from the first cell to the second cell from the first cell, and then determines the first cell and the second community according to the cell switching request. Corresponding co-assessment of shared anchors, finally perform cell switching directly by the same shared anchor. Solved in the prior art user terminal in the cell boundary area of ​​the multistage of 5G base station, the switching process complex time long leads to the technical problem of the drop or talk unstable, reaching the simplified 5G cell switching process, shortened different A shared base station operator cell switching time to improve the technical effect of the user's experience.

[0080]Figure 4 A flow chart of another communication cell switching method provided herein. Such asFigure 4 As shown, the specific steps include:

[0081]S401, gets the neighboring area planning data.

[0082]In this step, the neighboring area planning data includes: related information corresponding to the first communication mode cell corresponding to the first carrier or the second operator, corresponding to the first operator or the second operator Information about the second communication mode cell.

[0083]Specifically, in the present embodiment, the first communication mode is 5G communication mode, the second communication mode is 4G communication mode. Neighborhood planning data is a 5G coverage area of ​​multi-operators to build shared, and each operator is responsible for the distribution of 5G communication cells in the geographic location.

[0084]In this embodiment, the first operator and the second operator jointly built and shared 5G base stations. Under the NSA network architecture, each operator increases 5G auxiliary carrier access and transceiver on the basis of the original 4G base station. The device can achieve 5G network coverage, which has the case where the 5G communication cell and the 4G communication cell are superimposed. Therefore, in order to facilitate subsequent operations, the 4G and 5G cells corresponding to different operators are needed, or the neighborhood distribution between 5G and 5G cells is required.

[0085]S402, according to the neighboring area planning data, determine the resort to be adjusted to the first operator and the second operator's shared boundary area.

[0086]In this step, specific includes:

[0087]According to the neighboring area planning data, it is determined that at least one of the first cells of the first operator is a neighbor zone relationship with at least one second cell of the second operator. The first cell is One communication mode community, the second community is the first communication mode cell or the second communication mode cell;

[0088]The first cell including the neighboring area is composed of at least one neighbor group in the second cell;

[0089]Get traffic information of the neighboring neighboring groups in the preset time;

[0090]If the traffic is less than or equal to the preset business threshold, the communication cell of the neighboring section is determined to be adjusted;

[0091]If the traffic is greater than the preset service threshold, according to the geographic location of all communication cells in the neighboring section, the communication cell that is closest to the geographic location is smaller than the number of adjusted cells is determined as to be adjusted. Community.

[0092]specific,Figure 5 A schematic diagram of the neighboring area distribution provided by the embodiment of the present application. Such asFigure 5 As shown, 5G cells 521-524 are neighboring regions, 4G cells 511 and 512 are neighboring regions. Moreover, the 5G cells 521, 522, and 524 and 4G cells 511 are constructed and managed by the first operator, 5G community 523 and 4G cells 512 are built and managed by the second operator.

[0093]In one possible situation, if only 5G community is considered, the 5G community 521-524 is determined to be a neighboring group, and the traffic volume of 5G communities 521-524 is obtained, and the sum of the sum of the traffic they carries will exceed. The business bearing capacity of the frequency band of 4G shared anchors is the preset business threshold. If there is no exceeds, the four 5G cells are determined to be adjusted to be adjusted. If the sum of the four 5G communities exceeds the preset business threshold, then according to the traffic volume of the four 5G communities, the traffic is ranked by more than one, then from the first place, it has been accumulated. If the service volume of the next cell is added, the accumulated amount exceeds the preset business threshold, and the accumulated 5G community will form a residential area. For example, the 5G community 521-524 traffic is: 100, 80, 150, 60, the traffic is ranked: the cell 523, the cell 521, the cell 522, the cell 524. The preset business threshold is 300, and the cell 523 and the cell 521 are determined to be adjusted to be adjusted.

[0094]It should be noted that the shared anchor to be adjusted is an unisoff anchor or to be adjusted in the cell, at least two different operators' unconfielding anchors.

[0095]Optionally, if there are multiple neighboring regions in the neighboring area, such as 7 neighboring regions, the sum of their traffic exceeds the preset business threshold, and when the accumulated service cell, the number of cells exceeds the number of preset cells, such as 4, only the top 4 cells are taken as the neighboring area to be adjusted. This can control the number of co-adjacent regions to avoid fluctuations in the same frequency loaded, causing channel clogging, affecting the user's experience.

[0096]In one possible case, the 5G cells 524 and 4G cells 512 may be disposed to be adjusted to the cell so that the user terminal can achieve 4G as the 4G anchor point corresponding to the 5G cell 524 from the 4G cell 512. Switch to improve the user from 4G to 5G switching speed.

[0097]S403, the communication band of the communication band to be adjusted to adjust to the communication band corresponding to the shared anchor.

[0098]In this step, in particular, the PCI and PRACH of the PCI and PRACH corresponding to the first base station corresponding to the first operator can be provided, the PCI and PRACH of the second base station corresponding to the second carrier, that is, the first base station and the second base station. The corresponding cell uses the same 4G central frequency point to share the carrier frequency band corresponding to the anchor. For example, the cell 521, cell 522, and cell 524 are adjusted, and the corresponding GSCN's SSB frequency point position is adjusted from 7853 to the cell 523 corresponding to the cell 7811.

[0099]S404, the cell switch request from the first cell to the second cell is obtained by the user end.

[0100]The principles and noun interpretations of this step are similar to S301, and will not be described here.

[0101]S405, determine the shared anchor corresponding to the second cell according to the cell switching request.

[0102]In this step, both the first cell corresponding to the first operator in 5G communication mode corresponds to the second cell of the second carrier corresponding to the 4G shared anchor point of the same frequency, for example, an LTE frequency point 1650.

[0103]S406, connect the client to the second cell based on the shared anchor and the cell switching request.

[0104]In the present embodiment, the first base station of the first operator will be adjusted from the SSB frequency of the corresponding first cell GSCN to 7811, according to the frequency point 7811 in the second operator according to the frequency point 7811. The second cell corresponding to the two base station, switches the first cell 5G-SCG secondary carrier wave corresponding to the user end into a 5G-SCG secondary carrier of the second cell.

[0105]The communication cell switching method provided in this embodiment, by acquiring a cell handover request from the first cell to the second cell from the first cell, and then determines the first cell and the second community according to the cell switching request. Corresponding co-assessment of shared anchors, finally perform cell switching directly by the same shared anchor. Solved in the prior art user terminal in the cell boundary area of ​​the multistage of 5G base station, the switching process complex time long leads to the technical problem of the drop or talk unstable, reaching the simplified 5G cell switching process, shortened different A shared base station operator cell switching time to improve the technical effect of the user's experience.

[0106]In order to facilitate the understanding of the beneficial effects of the present invention, the present invention uses existing foreign exchange and rate loss and switching delay of the same frequency switching and switching delay in the plurality of 5G cells. And shown in Table 2.

[0107]

[0108]Table 1

[0109]As can be seen from Table 1, the wireless communication rate before the user terminal is switched and the wireless communication rate in the switch is used, and the rate loss is around 74% by the existing foreign exchange method. The same frequency switching method according to the present application is only about 19%, which greatly improves the user's experience.

[0111]Table 2

[0112]As can be seen from Table 1, the contrast user terminal is at average switching between 1640ms at the time of using an existing foreign exchange method, and only 25 ms of the same frequency switching method according to the present application, greatly shortening the communication cell switching. Time long.
