[0047] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0048] Figure 1 The flowchart of the cell handover method provided by the embodiment of the present invention is shown, and the method is executed by a computer processing device. The computer processing device may include a mobile phone, a laptop computer, etc. Figure 1 As shown, the method includes the following steps:

[0049] Step 101: Obtain a measurement report of a target terminal and information about services to be transmitted.

[0050] In one embodiment of the present invention, measurement reports may be periodically reported by each optional terminal connected to the base station. By analyzing the measurement reports, the optional terminal from which the measurement report satisfies a preset event is determined as the target terminal. The preset event may include an LTE handover trigger event, such as at least one of events A1, A2, A3, A4, and A5.

[0051] In another embodiment of the present invention, the measurement report can also be reported by each optional terminal when a preset event is detected. The specific process may include each optional terminal receiving a measurement control instruction issued by the base station, and the measurement control instruction includes a judgment condition on whether the above-mentioned one or more preset events are met. If the optional terminal detects that the measurement report of the cell meets the above-mentioned judgment condition, the optional terminal, as the target terminal, will return the measurement report that meets the preset event to the base station.

[0052] In one embodiment of the present invention, the service information to be transmitted may be determined by QoS (Quality of Service) buffer data of the target terminal, and specifically may be the amount of service data to be transmitted, wherein the unit of the data amount may be bit.

[0053] Step 102: Determine multiple switchable cells and load information of each of the switchable cells according to the measurement report.

[0054] In one embodiment of the present invention, a cell in the measurement report that meets the preset conditions set by the base station in step 101 is determined as a switchable cell. The load information is used to characterize the current resource configuration and usage of the switchable cell, and may specifically include, for example, the total number of resources, resource utilization, and the conversion efficiency between resources and data volume. The resources may be physical resource blocks (PRBs), and the data volume may be the transmitted service traffic.

[0055] Step 103: Determine the service occupancy information of the target terminal for each of the switchable cells according to the load information and the information of the service to be transmitted.

[0056] In one embodiment of the present invention, the total number of resources and resource utilization in the load information can be used to determine the number of utilized resources in the handover cell, thereby obtaining data on the idle resources that the handover cell can allocate to the target terminal if the handover is made to the handover cell. Furthermore, considering that there is a certain conversion efficiency between resources and the amount of data that can be transmitted by these resources, the amount of data that can be transmitted by the handover cell can be calculated based on this conversion efficiency and the aforementioned number of idle resources.

[0057] The information on the services to be transmitted includes the amount of data to be transmitted, and the service occupancy includes the numerical relationship between the amount of data to be transmitted of the target terminal and the amount of data that can be transmitted of the switchable cell. This numerical relationship represents the degree to which the service demand of the target terminal, such as the amount of data to be transmitted, occupies the idle resources of the switchable cell after the target terminal enters the switchable cell.

[0058] In another embodiment of the present invention, the load information includes idle resource information and a resource conversion rate; the service information to be transmitted includes the amount of data to be transmitted for a GBR (Guaranteed Bit Rate) service; and the service occupancy information includes GBR service occupancy information. The idle resource information may include the number of idle resources in a switchable cell, and the resource conversion rate is the conversion relationship between the number of resources and the amount of transmitted data. A GBR service refers to a service with a minimum bit rate guaranteed to be carried by the system. Even when network resources are limited, a GBR service can maintain the corresponding bit rate.

[0059] Step 103 also includes: Step 1031: determining the total amount of transmittable data of each of the switchable cells according to the idle resource information and the resource conversion rate.

[0060] In one embodiment of the present invention, when the idle resource information is the number of idle resources of the switchable cell and the resource conversion rate is the conversion relationship between the number of resources and the amount of transmitted data, the product of the number of idle resources and the resource conversion rate is determined as the total amount of transmittable data of the switchable cell.

[0061] In yet another embodiment of the present invention, the measurement report includes signal coverage information, network mode information, frame structure information, bandwidth information, and uplink and downlink average PRB utilization of multiple candidate cells.

[0062] Among them, the signal coverage information may include information such as the signal strength and signal quality of the switchable cell, which may be an RSRP level value, etc. The cell with worse signal coverage needs to occupy more resources when transmitting the same amount of data.

[0063] The network mode information may include one of the LTE network transmission modes, such as TDD (Time Division Duplexing) or FDD (Frequency Division Duplexing). Different network mode information corresponds to specific frame structure information, which includes the subframe structure information that makes up the radio frame, where the subframe structure information includes subframe length, number of subframes, etc. For example, in the FDD frame structure, a 10ms radio frame consists of 10 1ms subframes, each of which consists of two 0.5ms time slots.

[0064] Bandwidth information includes channel bandwidth information, which is measured in MHz. The transmission bandwidth can be calculated based on the channel bandwidth. The unit of transmission bandwidth is RE (Resource Element). RE is the smallest unit that carries user information in LTE. It corresponds to one carrier in the frequency domain, one time slot (half a subframe, 0.5ms) in the time domain, or one symbol in the time domain and 15KHz in the frequency domain.

[0065] RB (Resource Block) is the smallest unit that can be scheduled in LTE. RB includes VRB (Virtual Resource Block) and PRB (Physical Resource Block). Virtual Resource Block (VRB) is the basic unit of resource allocation. Its size is the same as PRB. It is divided into centralized and distributed types. Physically, RB can be considered equivalent to PRB.

[0066] In yet another embodiment of the present invention, the determination of the idle resource information in step 1031 may include the following:

[0067] Step 311: Determine the switchable cell from the candidate cells according to the signal coverage information.

[0068] In one embodiment of the present invention, the signal coverage information may include information representing the cell reference signal reception strength, such as RSRP (Reference Signal Receiving Power) value or RSRQ (ratio of cell reference signal power to total cell signal power).

[0069] Determine whether the signal coverage information meets the signal coverage requirements of preset events such as A1, A2, A3, A4 and A5, and determine the candidate cell that meets the requirements as the switchable cell.

[0070] Step 312: Determine the equivalent number of PRBs per frame in uplink and downlink of the switchable cell according to the network mode information, frame structure information, and bandwidth information.

[0071] In one embodiment of the present invention, the calculation method of the equivalent PRB number per uplink and downlink frame can refer to the existing technology and will not be repeated here. The equivalent PRB number per uplink and downlink frame includes the equivalent PRB number per uplink frame (denoted as C U ), and the equivalent number of PRBs per downlink frame (denoted as C D ).

[0072] Step 313: Determine the idle resource information according to the equivalent PRB number per uplink and downlink frame and the uplink and downlink average PRB utilization rate.

[0073] In one embodiment of the present invention, the uplink and downlink average PRB utilization ratios include the uplink average PRB utilization ratio (denoted as P U ) and downlink average PRB utilization (denoted as P D ), correspondingly, the idle resource information includes the number of uplink idle resources and the number of downlink idle resources, wherein the number of uplink idle resources is C U (1-P U ), the number of downlink idle resources is C D (1-P b ).

[0074] Step 314: Determine the resource conversion rate according to the number of used PRBs and the amount of transmitted data.

[0075] In another embodiment of the present invention, the measurement report includes the uplink and downlink transmission data volume (respectively recorded as Vol_Tran U 、Vol_Tran D ) and the number of PRBs used in the statistical period (respectively recorded as Num_UsedRB U 、Num_UsedRB D ); Resource conversion rate includes uplink resource conversion rate (denoted as SE U ) and downlink resource conversion rate (denoted as SE D ). Among them, SE U Determined Its unit is Bit / RB; SE D Determined The unit is Bit / RB.

[0076] It should be noted that, considering that there are a large number of users in the switchable cell, user behavior changes a lot. If the statistical period is not determined appropriately, the resource conversion rate of the switchable cell may not be determined accurately enough and cannot reflect the current actual resource conversion rate. Therefore, in another embodiment of the present invention, when the number of users in the switchable cell is greater than the preset number threshold, the statistical period is updated periodically to obtain the resource conversion rate within the updated statistical period.

[0077] Step 1032: Determine the GBR service occupancy information according to the amount of data to be transmitted of the GBR service and the total amount of transmittable data.

[0078] In one embodiment of the present invention, GBR service occupancy information is used to indicate the remaining idle resources of a handover cell after completing the target terminal's transmission service if the target terminal is handed over to the handover cell. The greater the remaining resources, the less impact the target terminal's resource occupancy has on the handover cell. Therefore, the difference between the total amount of transmittable data and the amount of GBR service data to be transmitted can be determined as the remaining transmittable data amount, and the remaining transmittable data amount can be determined as the GBR service occupancy information.

[0079] Specifically, the GBR service occupancy information includes uplink GBR service occupancy information (denoted as ω U ), uplink GBR service occupancy information (denoted as ω D ), the GBR service data volume to be transmitted includes the uplink GBR service data volume to be transmitted (recorded as GBR U ) and the amount of data to be transmitted for downlink GBR services (denoted as GBR D ) then determine ω U =C U (1-P U )SE U -GBR U ;ω D =C D (1-P D )SE D -GBR D .

[0080] In another embodiment of the present invention, it is considered that in addition to GBR service requirements, users may also have a certain proportion of non-GBR service requirements. After determining the occupancy information of GBR services with higher service priority, the occupancy status of non-GBR services after handover can also be determined. In this way, the GBR service occupancy information and the non-GBR service occupancy information are comprehensively considered, and a switchable cell is determined that can meet the transmission requirements of the target terminal for service types with higher rate requirements while also meeting the transmission requirements of other service types to the greatest extent possible, thereby fully utilizing the idle resources of the switchable cell and improving the overall user experience after handover.

[0081] Therefore, in another embodiment of the present invention, the load information further includes user quantity information; the information on services to be transmitted further includes the amount of data to be transmitted for non-GBR services; and the service occupancy information further includes non-GBR service occupancy information.

[0082] The user quantity information may specifically be the average number of synchronous users in the uplink and downlink of the switchable cell, including the average number of synchronous users in the uplink (denoted as N U ), the average number of downlink synchronous users (denoted as N D The non-GBR service occupancy information is used to indicate the extent to which the switchable cell can meet the non-GBR service transmission requirements of the target terminal. For example, if the non-GBR service occupancy information is 30%, it indicates that the switchable cell can meet 30% of the non-GBR service data to be transmitted of the target terminal.

[0083] Therefore, step 103 may further include: step 1033: determining the amount of data that can be transmitted for the non-GBR service according to the user quantity information, signal coverage information, and GBR service occupancy information.

[0084] In one embodiment of the present invention, taking into account the transmission characteristics of non-GBR services, parameters that are positively correlated with data transmission are normalized according to a certain ratio to obtain corresponding factors, which are added to the result of the normalization of the GBR service occupancy information to obtain the sum of the factors; correspondingly, parameters that are negatively correlated with data transmission are converted according to a certain ratio and subtracted from the aforementioned sum of factors to obtain the amount of data that can be transmitted by the non-GBR service.

[0085] In another embodiment of the present invention, the negatively correlated parameters may include the above-mentioned user quantity information, and the positively correlated parameters may include the above-mentioned signal coverage information and SINR (Signal to Interference plus Noise Ratio, signal-to-noise ratio), etc.

[0086] In one embodiment of the present invention, step 1033 further includes:

[0087] Step 331: normalize the user quantity information, signal coverage information, and GBR service occupancy information respectively to obtain a user quantity factor, a signal coverage factor, and a GBR service occupancy factor.

[0088] In one embodiment of the present invention, considering that the units of the user number information, signal coverage information, and GBR service occupancy information are not consistent, they cannot be directly integrated. Therefore, the corresponding normalization coefficients are determined according to the unit conversion relationship between the user number information, signal coverage information, and GBR service occupancy information, and are denoted as δ1, δ2, and δ3 respectively. Then, the user number factor, signal coverage factor, and GBR service occupancy factor are δ1ω, respectively. D ,δ2N D and δ3RSRP.

[0089] Step 332: Determine the sum of the GBR service occupancy factor and the signal coverage factor.

[0090] In one embodiment of the present invention, the quality of signal coverage is positively correlated with resource utilization and data transmission. The better the signal coverage, the greater the amount of data that can be transmitted by the idle resources of the switchable cell unit. Therefore, the signal coverage factor and the GBR service occupancy factor are summed.

[0091] Step 333: Determine the amount of data that can be transmitted for the non-GBR service based on the difference between the sum of the factors and the user quantity factor.

[0092] In one embodiment of the present invention, the greater the number of users, the greater the load of the switchable cell, and the more likely it is that the idle resources will be occupied by other users after the switch. Therefore, the number of users does not utilize the transmission of data of non-GBR services, and the user number factor is subtracted from the factor sum. Specifically, the amount of data that can be transmitted by non-GBR services includes the amount of data that can be transmitted by uplink non-GBR services and the amount of data that can be transmitted by downlink non-GBR services, which are respectively determined as δ1ω U -δ2N U +δ3RSRP、δ1ω D -δ2N D +δ3RSRP.

[0093] Step 1034: Determine the non-GBR service occupancy information according to the non-GBR service transmittable data volume and the non-GBR service to-be-transmitted data volume.

[0094] In one embodiment of the present invention, the non-GBR service transmittable data volume includes the uplink non-GBR service transmittable data volume and the downlink non-GBR service transmittable data volume, which are respectively recorded as Buff_NoGBR U 、Buff_NoGBR D .

[0095] Considering that the priority of non-GBR services is relatively low, in the case of limited network resources, they are not compulsorily satisfied like GBR services. Therefore, unlike the step X in which the difference between the amount of data that can be transmitted by the GBR service and the amount of data to be transmitted by the GBR service is determined as the GBR service occupancy information, in one embodiment of the present invention, the ratio of the amount of data to be transmitted by the non-GBR service to the amount of data that can be transmitted by the non-GBR service is determined as the non-GBR service occupancy information. That is, the non-GBR service occupancy information includes the uplink non-GBR service occupancy information (denoted as ), and downlink non-GBR service occupancy information (recorded as ),but

[0096] Step 104: Determine a target cell from the switchable cells according to the service occupation information.

[0097] In one embodiment of the present invention, considering that the priority of GBR services is higher than that of non-GBR services, it is first determined whether the idle resources of the switchable cell can meet the GBR service transmission requirements of the target cell, and then the target cell is determined based on whether the non-GBR service transmission requirements are met.

[0098] In another embodiment of the present invention, the non-GBR service occupation information includes uplink non-GBR service occupation information and downlink non-GBR service occupation information; step 104 further includes:

[0099] Step 1041: Determine the switchable cell whose GBR service occupation information meets the preset service occupation condition as the preferred switching cell.

[0100] In one embodiment of the present invention, the preset service occupation condition includes that the GBR service occupation information is greater than or equal to zero, specifically including ω U is not less than zero, and ω D Not less than zero.

[0101] The preset service occupancy condition is used to indicate whether the idle resources of the handover cell can meet the transmission resource requirements of the target terminal's GBR service data to be transmitted. This avoids the situation where the idle resources of the handover cell are insufficient to transmit all the target terminal's GBR service data to be transmitted after the target terminal switches in.

[0102] Step 1042: Determine the weighted service occupancy information of each of the preferred switching cells according to the uplink non-GBR service occupancy information and the downlink non-GBR service occupancy information.

[0103] In one embodiment of the present invention, the weighted service occupancy information is Kφ U+(1-K)φ D ; Among them, K is the uplink service weight, and 1-K is the downlink service weight.

[0104] Step 1043: Determine the target cell from the preferred switching cells according to the weighted service occupancy information.

[0105] In one embodiment of the present invention, the handover cell with the largest weighted service occupancy information is determined as the target cell.

[0106] In yet another embodiment of the present invention, when there is no preferred switching cell that meets the preset service occupation condition, the switchable cell with the largest weighted service occupation information is directly determined as the target cell.

[0107] In another embodiment of the present invention, when there is no preferred switching cell that meets the preset service occupancy conditions, the GBR service occupancy information and the weighted service occupancy information can be weighted and summed again to obtain comprehensive weighted occupancy information, and the switchable cell with the largest comprehensive weighted occupancy information is determined as the target cell.

[0108] Step 105: Access the target terminal to the target cell.

[0109] In one embodiment of the present invention, after the target cell is determined, a handover execution instruction is sent to the target terminal. The handover execution instruction includes connection information of the target cell, so that the target terminal accesses the target cell in a random access manner.

[0110] The embodiment of the present invention obtains the measurement report and service information to be transmitted of the target terminal; determines the load information of multiple switchable cells and each switchable cell based on the measurement report; determines the service occupancy information of the target terminal for each switchable cell based on the load information and the service information to be transmitted; determines the target cell from the switchable cell based on the service occupancy information; connects the target terminal to the target cell, thereby determining the switchable cell that can provide the best perception for the target terminal based on the uplink and downlink service transmission requirements of the target terminal itself and the load conditions of the switchable cell that can be used as the switching target, while also minimizing the degradation of the user perception experience after switching due to the increase in the load of the switchable cell after switching or the mismatch between the available resources for uplink and downlink services and the service requirements of the target terminal. The embodiment of the present invention can overcome the problem of poor effect caused by switching based on the single indicator of coverage in the prior art, and improve the user perception effect after cell switching.
