Description

Technical Field

[0001] The present application relates to the field of cellular mobile communication technology, and in particular to a paging frame offset configuration method, device and apparatus. Background Art

[0002] In a cellular mobile communication system, when the core network needs to communicate with a UE (User Equipment) in a non-connected state, it will notify the UE to access the network through a paging message. In order to reduce UE power consumption, the system uses discontinuous reception (DRX) to detect paging requests in the RRC_IDLE and RRC_INACTIVE states. During the paging process, the system calculates the paging timing based on predefined parameters such as the paging cycle, number of paging frames, and paging frame offset. However, when multiple co-frequency cells send paging messages at the same time, interference will occur, affecting the paging success rate. Current methods for improving paging success rates (such as blank subframe coordination, frequency domain resource coordination, etc.) have their own limitations.

[0003] From the paging frame number calculation formula defined in the 3GPP (3rd Generation Partnership Project) protocol, two pieces of information can be obtained: 1. UEs are divided into N groups, i.e., paging UE groups, based on UE_ID (User Equipment Identifier), and 2. The paging frame offset (PF_OFFSET) can adjust the position of the UE paging frame in the paging cycle. In a network, the paging cycle (T) and the number of paging frames in the paging cycle (N) of cells of the same station type (such as all macro stations) are generally the same, which will cause paging interference. The paging frame offset (PF_OFFSET) between cells can be adjusted to avoid paging interference from the same paging UE group in neighboring areas and improve the paging success rate.

[0004] Therefore, how to adjust the paging frame offset between cells to improve the paging success rate is a problem that needs to be solved urgently.

[0005] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] Based on this, the present application proposes a paging frame offset configuration method of the first embodiment, please refer to Figure 1The paging frame offset configuration method includes steps S10 to S40:

[0044] Step S10, counting the number of intra-frequency handover requests of neighboring cells of the serving cell;

[0045] It should be noted that the wireless communication system will make statistics for various events involving the air interface, that is, KPI indicator statistics reporting. For the statistical objects, KPI indicators are divided into different indicators such as base station level, cell level, and neighboring cell pair level. The number of intra-frequency handover requests at the neighboring cell pair level refers to the number of intra-frequency handover requests that occur between adjacent cells. The number of intra-frequency handover requests refers to the process of disconnecting the wireless connection at the cell boundary and establishing a new wireless connection with another cell when the user (UE) moves from one cell to another. This process is called cell handover. If the two cells use the same wireless spectrum, that is, intra-frequency handover, the number of intra-frequency handovers performed by the user is the number of intra-frequency handover requests. If the two are different, it is an inter-frequency handover. An adjacent cell refers to a cell around the current serving cell that shares part of the coverage area or spectrum resources with the serving cell. Usually, these cells have a frequency adjacency relationship with the serving cell, including intra-frequency cells, inter-frequency cells, or cells of heterogeneous networks (such as macro cells and micro cells).

[0046] For example, a cellular mobile communication system is composed of continuous coverage of cells one by one, and each cell has a number of adjacent cells, namely neighboring cells (neighboring cells). Figure 2 Cellular mobile communication network coverage map, for service cell P, its adjacent cells are P1, P2, P3, P4, P5, P6, etc. P1, P2, P3, P4 cells use the same radio spectrum as P cell. When a user switches from P1 cell to an adjacent P cell, the wireless connection with P1 cell is disconnected, and a same-frequency handover request is sent to P cell. If a user switches between adjacent cells with different radio spectra, the user sends a different-frequency handover request to the switched cell.

[0047] Step S20, selecting a preset number of first neighboring cells from the neighboring cells based on the number of intra-frequency handover requests;

[0048] It should be noted that the reason for selecting the first neighboring cell with a preset number of neighboring cells based on the number of same-frequency handover requests is that in a cellular communication system, the ideal state is that each cell is adjacent to only 6 cells, but in fact, each cell may have dozens or even hundreds of valid neighboring cells. In this case, it is only necessary to ensure that several neighboring cells adjacent to the serving cell and with the most frequent same-frequency handover requests can be staggered in the time-frequency domain to improve the paging success rate. The value of the preset number of neighboring cells is set according to the actual application scenario and is not limited in this embodiment.

[0049] Specifically, the adjacent cells are sorted according to the number of intra-frequency handover requests, and the first n first adjacent cells are selected.

[0050] Step S30, obtaining parameter configuration information of the first neighboring cell;

[0051] It should be noted that the parameter configuration information includes PF_OFFSET (paging frame offset), T (paging cycle), N (number of paging frames in a paging cycle), Ns (number of paging times contained in a paging frame), etc. If these four parameters are all the same, the paging times calculated by the UE (user equipment) of the same paging group are exactly the same, which will cause interference between the same-frequency cells. Acquisition refers to the serving cell extracting relevant paging parameter configuration information from the first adjacent neighboring cell through a network protocol or signaling process.

[0052] Specifically, the serving cell obtains parameter configuration information from the first neighboring cell through a network protocol or a signaling process.

[0053] Step S40, determining whether the number of second neighboring cells in the first neighboring cells that have the same parameter configuration information as the serving cell is greater than a preset neighboring cell number threshold, and if so, calculating the paging frame offset of the serving cell;

[0054] It should be noted that the reason for judging whether the number of second neighboring cells in the first neighboring cells that have the same parameter configuration information as the serving cell is greater than the preset neighboring cell number threshold is that it is necessary to optimize only when the serving cell has the same parameter configuration information as a certain number of co-frequency neighboring cells. At this time, it can be considered that the paging interference to the serving cell is large and there is room for optimization. Otherwise, it is considered that a relatively ideal state has been reached and no re-optimization is required.

[0055] Optionally, the value range of the neighbor cell number threshold may be {0, 1, preset number of neighbor cells}.

[0056] The value of the neighboring cell number threshold is 0, that is, whether the parameter configuration information of the serving cell and the neighboring cell is the same is not considered, and optimization is performed directly. The value is the preset number of neighboring cells, that is, the parameter configuration information of the serving cell and the neighboring cell is the same before optimization is performed, that is, there is room for optimization at this time. The position of the paging frame is calculated by three parameters: PF_OFFSET (paging frame offset), T (paging cycle), and N (number of paging frames in the paging cycle). The value of the neighboring cell number threshold is 0, that is, regardless of whether the parameter configuration information of the serving cell and the neighboring cells with the preset number of neighboring cells is the same, the PF_OFFSET of the serving cell is generated according to the algorithm. At this time, it is impossible to guarantee that the PF_OFFSET of the serving cell and the neighboring cells with the preset number of neighboring cells are different, and whether there is an effect of reducing paging interference is unknown. When the neighboring cell number threshold is equal to the preset number of neighboring cells, the parameter configuration information of the serving cell and the neighboring cells with the preset number of neighboring cells are all the same. Only by optimizing PF_OFFSET can the purpose of staggering the paging frames of UEs in the same paging group in time latitude be achieved, thereby reducing paging interference. The value of 1 means that optimization can be performed as long as the parameter configuration information of the serving cell is the same as that of at least one neighboring cell. The purpose of this setting is that when the parameter configuration information of the serving cell is the same as that of any adjacent cell, there may be a paging interference problem. In this case, even if the optimization range is small, it can reduce the interference to a certain extent and improve the paging success rate.

[0057] In a feasible implementation manner, the parameter configuration information includes a paging cycle and a number of paging frames; step S40 may include:

[0058] It is determined whether the number of second neighboring cells in the first neighboring cells that have the same paging cycle and paging frame number as the serving cell is greater than a preset neighboring cell number threshold; if so, the paging frame offset of the serving cell is calculated.

[0059] The reason for judging whether the paging cycles and the number of paging frames of the two are the same is that the paging cycles (T) and the number of paging frames (N) of the serving cell and the neighboring cells of the preset number of neighboring cells are configured the same, so that the purpose of staggering the paging frames of UEs in the same paging group can be achieved by optimizing PF_OFFSET.

[0060] Step S50: Update the configuration of the paging frame offset in the parameter configuration information of the serving cell.

[0061] Specifically, the value of the paging frame offset is updated in the parameter configuration information of the serving cell to be the calculated paging frame offset, and the updated parameter configuration information is broadcast through the system. The calculated paging frame offset is different, and the position where the paging frame of the serving cell appears in the paging cycle is different from the position where the paging frame appears in a certain number of adjacent cells, thereby improving the paging success rate.

[0062] In this embodiment, the number of co-frequency handover requests of the neighboring cells of the serving cell is counted; the first neighboring cell with a preset number of neighboring cells is selected from the neighboring cells based on the number of co-frequency handover requests, so as to select the first neighboring cell that may interfere with the serving cell from all the neighboring cells; it is determined whether the number of second neighboring cells with the same parameter configuration information as the serving cell in the first neighboring cell is greater than the preset neighboring cell number threshold, if so, it means that the second neighboring cells exceeding the neighboring cell number threshold will interfere with the paging of the serving cell, resulting in a high paging failure rate of the serving cell, then the paging frame offset of the serving cell is calculated; the configuration of the paging frame offset is updated in the parameter configuration information of the serving cell. Through system broadcasting, paging is performed at different times of the paging cycle, thereby improving the paging success rate.

[0063] In addition, the concepts of adjacent cells, first adjacent cells and second adjacent cells mentioned in the first embodiment. Adjacent cells refer to cells adjacent to the serving cell. These adjacent cells may have the same or different radio spectrum as the serving cell. The first adjacent cells are adjacent to the serving cell and have the most frequent frequency switching requests (preset number of adjacent cells). The second adjacent cells are those cells in the first adjacent cells that have the same parameter configuration information as the serving cell. For example, the service cell Cell_s has the full set of neighboring cells (all neighboring cells) {Cell_n0, Cell_n1, Cell_n2, Cell_n3, Cell_n4, Cell_n5.....}, and the neighboring cell pairs of Cell_s are: Cell_s->Cell_n0, Cell_s->Cell_n1, Cell_s->Cell_n2, Cell_s->Cell_n3..., and the number of same-frequency switching requests at the neighboring cell pair level is counted, that is, the number of same-frequency switching requests that occur from Cell_s to Cell_n0...Cell_s to Cell_nm. Among them, the neighboring cell set {Cell_n0, Cell_n2, Cell_n4.....} is the same-frequency neighboring cell. The first neighboring cell with a preset number of neighboring cells with a large number of same-frequency switching requests is selected from the same-frequency neighboring cells, and then the second neighboring cell with the same parameter configuration information as the service cell is screened out from the first neighboring cell. By screening from the neighboring cell to the second neighboring cell, several neighboring cells that have the greatest interference with the service cell are obtained, which is convenient for the subsequent calculation of the paging frame offset.

[0064] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, step S40, the step of calculating the paging frame offset of the serving cell includes steps S41 to S43:

[0065] Step S41, calculating the maximum paging frame offset based on the paging cycle and the number of paging frames;

[0066] It should be noted that the paging cycle refers to a periodic time window defined by the system, during which the UE monitors the paging messages of the network to save terminal power consumption, which is expressed as T; the number of paging frames refers to the number of radio frames used to send paging messages within a paging cycle T, which is expressed as N. Through these two parameters, the possible paging frame range within a paging cycle can be determined, which is 0 to the maximum paging frame offset (all values ​​are integers).

[0067] In a feasible implementation, step S41 may include the following steps:

[0068] The maximum paging frame offset is calculated according to the formula: PF_OFFSET_n=(T div N), where PF_OFFSET_n is the maximum paging frame offset, T is the paging cycle, and N is the number of paging frames.

[0069] It should be noted that the maximum paging frame offset PF_OFFSET_n is a configuration value defined by the 3GPP protocol, but may not be a commonly used multiplexing value.

[0070] Specifically, T div N represents the integer of the quotient of the paging cycle T divided by the number of paging frames N, and the obtained PF_OFFSET_n is the maximum paging frame offset.

[0071] Step S42, obtaining the maximum paging frame offset and the preset maximum multiplexing paging frame offset to calculate the actual maximum paging frame offset;

[0072] In a feasible implementation, step S42 may include the following steps:

[0073] The actual maximum paging frame offset is calculated according to the formula: PF_OFFSET_m=Min(PF_OFFSET_n, PF_OFFSET_max), where PF_OFFSET_m is the actual maximum paging frame offset and PF_OFFSET_max is the maximum multiplexed paging frame offset.

[0074] It should be noted that PF_OFFSET_max is the maximum multiplexed paging frame offset, indicating the maximum multiplexable value of the paging frame offset. For example, the maximum multiplexed paging frame offset is 3, that is, different cells reuse three values ​​0, 1, and 2. The value is 6, that is, different cells reuse six values ​​0, 1, 2, 3, 4, and 5. The larger the multiplexed frame offset, the better. However, in cellular mobile communication systems, values ​​such as 3 and 6 are usually selected for network planning. For example, the PCI of adjacent cells is different in modulus 3. This is a common network planning strategy. Multiplexing means that the values ​​obtained by modulo a multiplexing coefficient of the physical cell identifiers of different cells cannot be the same, such as the PCI of adjacent cells cannot be the same in modulus 3. PF_OFFSET_m=Min(PF_OFFSET_n, PF_OFFSET_max) means that the smaller value between the maximum paging frame offset and the additionally set maximum multiplexed paging frame offset is taken as the actual maximum paging frame offset. In this way, the available values ​​of the paging frame offset are 0, 1,...actual maximum paging frame offset-1.

[0075] In addition, it should be noted that the maximum multiplexed paging frame offset is the maximum multiplexable value of the additionally set paging frame offset. The maximum multiplexed paging frame offset and the maximum paging frame offset are smaller to avoid the maximum multiplexed paging frame offset being set too large and exceeding the maximum paging frame offset defined by the 3GPP protocol. A value greater than the maximum paging frame offset is an abnormal configuration value.

[0076] Step S43: Obtain the physical cell identifier of the serving cell, the preset physical cell identifier offset and the actual maximum paging frame offset to calculate the paging frame offset.

[0077] In a feasible implementation, step S43 may include the following steps:

[0078] The paging frame offset is calculated according to the formula: PF_OFFSET=((PCI+PCI_Offset) mod PF_OFFSET_m), where PF_OFFSET is the paging frame offset, PCI is the physical cell identifier, and PCI_Offset is the physical cell identifier offset.

[0079] It should be noted that the physical cell identifier PCI (Physical Cell Identifier) ​​is an identifier used to uniquely identify a cell in a cellular network, and the physical cell identifier offset PCI_Offset is an offset based on the current physical cell identifier PCI, which is used to participate in the calculation of the paging frame offset PF_OFFSET. The design of the physical cell identifier offset is to avoid some abnormal situations. For example, when the network plans the physical cell identifier, it will try its best to ensure that the physical cell identifier modulus 3 between neighboring cells with frequent co-frequency switching, but it is inevitable that there will be situations where they cannot be staggered. At this time, the two cells can set different PCI_Offsets to ensure that the self-optimized paging frame offsets are different. The setting of the physical cell identifier offset PCI_Offset needs to take into account the paging configuration parameters that may be adjusted during dynamic network optimization. For example, in paging optimization, the PCI_Offset is appropriately adjusted according to the cell load and interference conditions to ensure that the calculation results of the paging frame offset PF_OFFSET are independent of each other.

[0080] In addition, when the neighbor cell number threshold is 0, the neighbor cell parameter configuration is not considered, and the paging offset frame is directly calculated based on PF_OFFSET=((PCI+PCI_Offset) mod PF_OFFSET_m).

[0081] For example, two adjacent cells have PCI1=10, PCI2=11, and PF_OFFSET_m=32. The paging frame offset PF_OFFSET is calculated directly through PCImod PF_OFFSET_m. The calculated results are the same. At this time, the paging frame offsets are the same, and the positions of the two in the paging cycle cannot be staggered. PCI_Offset1=3 and PCI_Offset2=7 can be set to ensure that the paging frame offsets calculated by the two are different.

[0082] In a feasible implementation, step S42 may include the following steps:

[0083] The paging frame offset is calculated according to the formula: PF_OFFSET = (PCI mod PF_OFFSET_m).

[0084] It is understandable that, usually when planning the network, the PCIs of adjacent cells will be staggered according to mode 3 or mode 6, which is a basic rule. However, the actually constructed network will deviate from the plan. For example, the PCI of the first adjacent cell with the preset number of adjacent cells, or even the first adjacent cell with the most co-frequency switching requests, and the PCI of the serving cell cannot be completely staggered by mode 3 / 6. At this time, if PCI mod PF_OFFSET_m is fixedly used to generate the paging frame offset, the paging frame offset calculated by the serving cell and the strongest adjacent cell may be fixed to be the same, so the first implementation method adds the physical cell identifier offset to participate in the calculation of the paging frame offset, which can ensure that the calculated paging frame offsets are different, while the second implementation method, for the case where different paging frame offsets can be calculated directly using PCI mod PF_OFFSET_m, the second implementation method can save paging frame calculation resources.

[0085] In this embodiment, the configuration of the paging frame offset is associated with the PCI of the cell to ensure that the paging frame offsets of the same-frequency cells with serious overlapping coverage are different. To the greatest extent possible, the PF_OFFSET values ​​between the same-frequency neighboring cells are different, thereby reducing the interference caused by the paging messages of the same paging UE group and improving the paging success rate.

[0086] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those of the first and / or second embodiments can be referred to the above description, and will not be described in detail later. On this basis, the step S10 of counting the number of same-frequency handover requests of the neighboring cells of the serving cell includes steps S11 to S12:

[0087] Step S11, set a timer, when the timer is within the preset timing period, count the number of intra-frequency switching requests of each adjacent cell; step S12, when the timer exceeds the timing period, sort the intra-frequency switching requests of each adjacent cell from large to small.

[0088] It should be noted that the preset timing period can be set to weekly or monthly granularity. The reason for this setting is that these two granularities can better balance the statistical accuracy and the actual network optimization requirements. Weekly granularity: can quickly reflect short-term user behavior changes or network load fluctuations, suitable for real-time adjustment of dynamic optimization strategies. Monthly granularity: can capture longer-term network usage patterns and interference conditions, provide data support for more stable network optimization, and is especially suitable for network planning or long-term optimization decisions.

[0089] Specifically, refer to Figure 4, count the "number of same-frequency handover requests" (that is, count the number of same-frequency handover requests of each neighboring cell) by target neighboring cells within the monthly or weekly granularity period, and judge whether the timer exceeds the monthly or weekly granularity during the statistics. If not, continue to count. If so, sort the "number of same-frequency handover requests" of multiple neighboring cells (that is, sort from large to small according to the number of same-frequency handover requests of each neighboring cell), and output the TOP_n neighboring cells after sorting. Top_n is the object ranked in the first n positions after sorting according to certain rules. The TOP_n neighboring cell is the first neighboring cell (the first n) of the preset number of neighboring cells, and then set the "number of same-frequency handover requests" of the neighboring cell pair counter of the number of neighboring cells to 0. In addition, n can be set to PF_OFFSET_m-1, that is, the available PF_OFFSET-1, so that the optimal value is that the PF_OFFSET of the serving cell and its TOP_n neighboring cells are different.

[0090] In this embodiment, the number of intra-frequency handover requests of neighboring cells of the serving cell is counted and sorted through a timer-based and periodic statistical mechanism, so as to accurately identify the target neighboring cells of high-frequency handover.

[0091] For example, refer to Figure 3 and Figure 5 , combined with one or more of the above embodiments, the technical solution of this application is briefly described:

[0092] Reference Figure 5 First, the timer determines whether it has timed out, then the number of co-frequency switching requests of the neighboring cells of the serving cell is counted and sorted. When the timer times out and reaches the timing period, the Top_n neighbor list is obtained to obtain the neighboring cells of the preset number of neighboring cells (that is, Top_n), and then the paging configuration parameters of the Top_n neighboring cells are obtained. Then, the information of the neighboring cells of the preset number of neighboring cells is obtained, for example, the neighboring cell set {Cell_n1, Cell_n2, ..., Cell_nn}, and then the parameter configuration information {Cell_n1{T, N}, Cell_n2{T, N}, ..., Cell_nn{T, N}} of the neighboring cell set {Cell_n1, Cell_n2, ..., Cell_nn} is queried one by one, mainly to query the information of the paging cycle and the number of paging frames, and then determine whether the number of neighboring cells consistent with the paging parameters of the serving cell is greater than the neighboring cell number threshold M. If so, the paging frame offset is calculated. First, PF_OFFSET_n=(T div N) is calculated.

[0093] Then calculate PF_OFFSET_m=Min(PF_OFFSET_n, PF_OFFSET_max)

[0094] Finally, the paging frame offset PF_OFFSET of the serving cell is calculated as ((PCI+PCI_Offset) mod PF_OFFSET_m), the serving cell parameter configuration information is updated, the obtained paging frame offset PF_OFFSET is updated as the paging frame offset of the serving cell, and the serving cell system broadcast is updated.

[0095] The present application provides a paging frame offset configuration device, which includes: at least one processor; and a memory connected to the at least one processor in communication; wherein the memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the paging frame offset configuration method in the above-mentioned embodiment 1.

[0096] The paging frame offset configuration device provided by the present application adopts the paging frame offset configuration method in the above embodiment, which can solve the technical problem of how to adjust the paging frame offset between cells to improve the paging success rate.
