Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, including but not limited to combinations of embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any inventive step are within the scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings (if any) are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

However, since different carriers with different frequency bands are generally used between different operators, the inter-frequency handover is required when the ue needs to switch the cells in a region where multiple operators share the base station, but the ue and/or the base station do not directly implement the inter-frequency handover between the cells of the new generation of communication technology for the new generation of communication technology, which results in that the ue must implement the inter-frequency handover by the communication technology of the previous generation

For example, at present, NR (New Radio over the air) inter-frequency handover under an NSA (Non-stand alone networking) architecture is not supported between a 5G base station and a user equipment, but operating frequency bands of different operators are different, that is, cells corresponding to shared base stations of different operators are inter-frequency, so that when the user equipment is located at the edge of the coverage area of a signal of a shared base station of multiple operators, the user equipment needs to perform handover between cells corresponding to different operators, and the handover can be performed only by inter-frequency handover of 4G core networks corresponding to two handover cells. The existing 4G core network can realize the inter-frequency handover of the 4G communication cell directly between the user equipment and the base station. Therefore, in the existing 5G communication mode, if a user terminal wants to perform 5G cell handover between different operators, the user terminal needs to perform pilot frequency handover to a 4G pilot frequency anchor point of another operator corresponding to a 5G target handover cell in the 4G communication mode, and then add a 5G auxiliary carrier to access the 5G target handover cell.

However, the existing cell switching method is complex in process and long in time consumption, so that the technical problem that a call drop or call instability may occur when a 5G user is switched in a cell.

To solve the above problems, the present application provides a method for handing over a communication cell, which is described below with reference to the following embodiments and accompanying drawings.

For the convenience of understanding, the following description explains the terms related to the embodiments of the present application.

SSB (Synchronization Signal and PBCH block, Synchronization Signal and physical broadcast channel block): the system consists of three parts, namely Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS) and PBCH (Physical Broadcast Channel). In NR of 5G, the concept of SSB appears, which is simply formed by combining the original primary synchronization sequence, secondary synchronization sequence, physical broadcast channel and demodulation reference signal, and is mainly used for downlink synchronization.

GSCN (Global Synchronization Channel Number): when the terminal just starts up to search the cell, it can only detect the SSB signal according to the frequency band supported by the operator and the terminal to perform the downlink time-frequency synchronization. The smaller granularity of the global Frequency grid leads to a larger value range of the NR-ARFCN (NR Absolute Radio Frequency Channel Number), and if blind detection is directly carried out according to the global Frequency grid, the synchronization delay is larger. In order to effectively reduce the Synchronization delay of this process, 3GPP has specifically defined the concept of Synchronization grid (Synchronization manager), and defines the search range by the GSCN.

In PCI (Physical Cell Identifier) LTE, a terminal distinguishes radio signals of different cells. The LTE system provides 504 PCIs, the concept of the LTE system is similar to that of 128 scrambling codes of the TD-SCDMA system, and when network management is configured, a number between 0 and 503 is configured for a cell. In the LTE cell search procedure, the specific cell ID is determined by retrieving the primary synchronization sequence (PSS, with 3 possibilities), the secondary synchronization sequence (SSS, with 168 possibilities), and a combination of them.

A PRACH (Physical Random Access Channel) is an Access Channel when a user equipment UE (user equipment) starts to initiate a call, and after receiving a FPACH (Fast Physical Access Channel) response message, the UE sends an RRC (Radio Resource Control) connection request message on the PRACH according to information indicated by a Node B to establish an RRC connection.

Fig. 1 is a schematic view of a scenario in which a ue switches a cell at a cell boundary position where multiple operators share a 5G base station according to the present application. As shown in fig. 1, a first operator establishes and manages a 5G base station and a cell 111, and a second operator establishes and manages a 5G base station and a 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, handover of the 5G communication cell is required.

Fig. 2 is a schematic diagram of a 5G cell handover process between different operators in the prior art. As shown in fig. 2, after the user terminal sends the handover request, the first operator base station deletes the first 5G carrier currently connected to the user terminal, that is, the wireless communication frequency band where the first 5G cell is located, and accesses the user terminal to the 4G communication mode, the first operator base station corresponds to the first shared anchor point, that is, the first 4G frequency point, under the 4G LTE, and then connects the user terminal to the second shared anchor point, that is, the 4G LTE, corresponding to the second operator base station by using the 4G inter-frequency handover technique, thereby completing the handover between the two base stations, and then the second operator base station accesses the user terminal to the target handover cell corresponding to the second 5G carrier, thereby completing the handover of the user terminal from the cell 111 to the cell 112 shown in fig. 1. It can be seen that the 5G cell handover process under the NSA networking architecture in the prior art is very complicated and time-consuming.

Fig. 3 is a flowchart illustrating a method for handing over a communication cell according to the present application. As shown in fig. 3, a method for switching a communication cell provided in an embodiment of the present application includes:

s301, a cell switching request sent by a user terminal and switched from a first cell to a second cell is obtained.

In this step, the first cell and the second cell are communication cells in a first communication mode, the first base station corresponding to the first cell is a base station that is constructed and managed by a first operator and is shared with a second operator, the second base station corresponding to the second cell is a base station that is constructed and managed by the second operator and is shared with the first operator, and the first base station and the second base station perform wireless communication using the shared anchor point with the same frequency.

Specifically, in this embodiment, the first communication mode is a 5G communication mode. The first cell and the second cell are located at the edge of a shared area established by corresponding operators.

S302, according to the cell switching request, a shared anchor point corresponding to the first cell and the second cell is determined.

In this step, the shared anchor is a communication anchor in a second communication mode, and the communication characteristic of the first communication mode is better than that of the second communication mode. In this embodiment, the second communication mode is a 4G communication mode.

Specifically, the shared anchor point is a communication frequency point in a 4G communication mode, and the first base station and the second base station can share the frequency point to perform wireless communication, that is, the two base stations realize the same frequency operation. Therefore, when the 5G cell is switched, the switching process of the pilot frequency anchor points among the 4G cells can be omitted, and the switching speed is accelerated.

S303, connecting the ue to the second cell according to the shared anchor and the cell switching request.

In this step, since the shared anchor of the 4G is not changed, that is, the first base station and the second base station operate at the same frequency, the inter-frequency handover is replaced by the inter-frequency handover, and the user terminal can be handed over from the first cell to the second cell only by switching the corresponding 5G auxiliary carrier on the basis of the shared anchor of the 4G.

In the method for switching a communication cell provided in this embodiment, a cell switching request sent by a user end for switching from a first cell to a second cell is obtained, then a shared anchor point with the same frequency corresponding to the first cell and the second cell is determined according to the cell switching request, and finally, the cell switching is directly performed through the shared anchor point with the same frequency. The technical problem that in the prior art, when a user terminal performs cell switching in a cell boundary area of a multi-operator shared 5G base station, the switching process is complex and time-consuming, so that call drop or call instability is caused is solved, the 5G cell switching process is simplified, the inter-operator cell switching time of different shared base stations is shortened, and the technical effect of improving the use experience of users is achieved.

Fig. 4 is a flowchart illustrating another method for handing over a communication cell according to the present application. As shown in fig. 4, the specific steps include:

s401, obtaining neighbor planning data.

In this step, the neighbor cell planning data includes: the information processing method includes the steps of obtaining information related to a first communication mode cell corresponding to a first operator or a second operator and information related to a second communication mode cell corresponding to the first operator or the second operator.

Specifically, in this embodiment, the first communication mode is a 5G communication mode, and the second communication mode is a 4G communication mode. The adjacent area planning data is the distribution situation of 5G communication cells which are built and managed by each operator in a shared 5G coverage area by the co-construction of multiple operators on the geographical position.

In this embodiment, a first operator and a second operator jointly establish and share a 5G base station, and under an NSA networking architecture, each operator adds a 5G auxiliary carrier access and transceiver device on the basis of an original 4G base station, so that 5G network coverage can be achieved, and thus, a situation of overlapping distribution of a 5G communication cell and a 4G communication cell occurs. Therefore, in order to facilitate subsequent operations, it is necessary to obtain neighboring cell distribution conditions between 4G and 5G cells or between 5G and 5G cells corresponding to different operators.

S402, determining a cell to be adjusted corresponding to a shared boundary area of a first operator and a second operator according to the adjacent cell planning data.

In this step, it specifically includes:

acquiring the traffic information of the neighbor block within a preset time;

if the traffic is less than or equal to a preset traffic threshold, determining the communication cell of the neighbor group as a cell to be adjusted;

and if the traffic is greater than the preset traffic threshold, determining the communication cells with the closest geographic positions and the number less than the number of the preset cells as the cells to be adjusted according to the geographic positions of all the communication cells in the neighbor cell group.

Specifically, fig. 5 is a schematic diagram of a distribution situation of a neighboring cell provided in the embodiment of the present application. As shown in fig. 5, the 5G cell 521-524 is a neighboring cell, and the

4G cells

511 and 512 are neighboring cells. Also,

5G cells

521, 522, and 524 and 4G cell 511 are established and managed by a first operator, and 5G cell 523 and 4G cell 512 are established and managed by a second operator.

In a possible case, if only the 5G cells are considered, determining the 5G cell 521-. If the sum of the traffic of the four 5G cells exceeds the preset traffic threshold, ranking is carried out according to the traffic of the 4 5G cells from more to less, then the traffic corresponding to the first name is accumulated until the accumulated amount exceeds the preset traffic threshold if the traffic of the next cell is added, and the 5G cells participating in accumulation form the cells to be adjusted. For example: the 5G cell 521-: 100, 80, 150, 60, then the traffic is ranked as: cell 523, cell 521, cell 522, and cell 524. If the preset traffic threshold is 300, the cell 523 and the cell 521 are determined as the cells to be adjusted.

It should be noted that the shared anchor point corresponding to the cell to be adjusted is an inter-frequency anchor point, or the cell to be adjusted at least includes inter-frequency anchor points of two different operators.

Optionally, if there are multiple neighboring cells in the neighbor cell group, for example, 7 neighboring cells, and the sum of their traffic amounts exceeds the preset traffic threshold, and when the traffic cells are accumulated, the number of the cells exceeds the preset number of the cells, for example, 4, then only the cell with the top 4 bits is taken as the neighboring cell to be adjusted. Therefore, the number of adjacent regions with the same frequency can be controlled, and the phenomenon that the use experience of a user is influenced due to channel blockage caused by the fluctuation of the service volume of the same-frequency bearer is avoided.

In a possible case, the 5G cell 524 and the 4G cell 512 may also be set as cells to be adjusted, so that when the user terminal switches from the 4G cell 512 to the 4G anchor point corresponding to the 5G cell 524, the 4G co-frequency switching may be implemented, so as to improve the switching speed of the user from 4G to 5G.

S403, adjusting the communication frequency band of the cell to be adjusted to the communication frequency band corresponding to the shared anchor point.

In this step, specifically, the PCI and PRACH of the first base station corresponding to the first operator and the PCI and PRACH of the second base station corresponding to the second operator may be set to be in a same frequency mode, that is, the cells corresponding to the first base station and the second base station use the same 4G central frequency point, that is, the carrier frequency band corresponding to the shared anchor point. For example, the cell to be adjusted: the frequency point positions of the SSBs of the corresponding GSCNs are adjusted from 7853 to frequency point 7811 corresponding to cell 523 in cell 521, cell 522 and cell 524.

S404, a cell switching request which is sent by a user terminal and is switched from a first cell to a second cell is obtained.

The principle and noun explanation of this step are similar to those of S301, and are not described herein again.

S405, according to the cell switching request, determining a shared anchor point corresponding to the first cell and the second cell.

In this step, the first cell corresponding to the first operator and the second cell corresponding to the second operator in the 5G communication mode both correspond to the same-frequency 4G shared anchor, such as LTE frequency 1650.

S406, connecting the ue to the second cell according to the shared anchor and the cell switching request.

In this embodiment, specifically, after the SSB frequency point position of the corresponding first cell GSCN is adjusted from 7853 to 7811 by the first base station of the first operator, the first cell 5G-SCG auxiliary carrier corresponding to the user end may be switched to the second cell 5G-SCG auxiliary carrier corresponding to the second cell according to the frequency point 7811 in the second cell corresponding to the second base station of the second operator.

In order to facilitate understanding of the beneficial effects of the present invention, the inventor of the present application compares the rate loss and the handover delay of the same-frequency handover between the existing inter-frequency handover and the present application when switching a plurality of 5G cells, as shown in tables 1 and 2.

TABLE 1

As can be seen from table 1, comparing the radio communication rate of the ue before handover with the radio communication rate during handover, the rate loss is about 74% by using the existing inter-frequency handover method. By adopting the same-frequency switching method, the rate loss is only about 19%, and the use experience of users is greatly improved.

NSA	Pilot frequency (ms)	Same frequency (ms)	Comparison (ms)
				1	1650	25	1625
2	1638	23	1615
				3	1576	24	1552
4	1659	26	1633
				5	1690	26	1664
Average	1642.6	24.8	1617.8

TABLE 2

It can be seen from table 1 that, compared with the existing pilot frequency handover method, the average handover delay is about 1640ms, while the same frequency handover method of the present application is only 25ms, which greatly shortens the delay time caused by the handover of the communication cell.
