Description

[Technical Field]

[0001] This invention relates to the field of communication technology, and in particular to a method and related equipment for determining the cell where a mobile terminal is based. [Background Technology]

[0002] In current communication scenarios, signal quality degrades after passing through buildings and entering indoor spaces. Therefore, co-frequency networking is often used to overcome this problem. Specifically, indoor base stations carry communication services for indoor cells, and outdoor base stations carry communication services for outdoor cells. However, mobile terminals located at the edge of indoor areas, such as users near windows, are simultaneously at the edge of both indoor and outdoor cells. This can lead to frequent cell handovers for edge users, resulting in a poor user experience. Current technologies often use methods to force edge users to camp in indoor cells to avoid frequent handovers. However, forcing edge users to camp in indoor cells can overload indoor base stations, leading to a degraded network experience for all users in the indoor cell. Therefore, determining the appropriate cell for edge users and improving the indoor user experience is a pressing issue that needs to be addressed. [Summary of the Invention]

[0003] To address the aforementioned issues, embodiments of the present invention provide a method and related equipment for determining the cell where a mobile terminal is based, which can improve the user experience for indoor users.

[0004] In a first aspect, embodiments of the present invention provide a method for determining the cell where a mobile terminal is stationed in an indoor network device, comprising:

[0005] The edge mobile terminal and the corresponding outdoor cell are determined based on the signal measurement information of the indoor mobile terminal accessing the indoor cell.

[0006] A first request is sent to the outdoor network device corresponding to the outdoor cell, so that the outdoor network device sends the network resource information of the candidate mobile terminal to the indoor network device according to the first request. The candidate mobile terminal is a mobile terminal that has accessed the outdoor cell and whose adjacent cell is the indoor cell.

[0008] The first network quality of the indoor cell and the second network quality of the indoor cell after the candidate mobile terminal accesses the indoor cell are determined based on the network resource information of the edge mobile terminal and the candidate mobile terminal.

[0009] If the quality of the second network is greater than that of the first network, then the indoor cell is determined to be the cell where the candidate mobile terminal will reside.

[0010] In this embodiment of the invention, edge mobile terminals in an indoor cell are determined using signal measurement information from mobile terminals.

Detailed Implementation Methods

[0054] To better understand the technical solutions in this specification, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments in this specification. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without inventive effort are within the scope of protection of this invention.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] In this embodiment of the invention, after identifying a candidate mobile terminal that is located indoors but accesses an outdoor cell, the candidate mobile terminal's first network quality before accessing the indoor cell and its second network quality after accessing the indoor cell are calculated based on the network resource information of the candidate mobile terminal and the edge mobile terminal, thereby determining the cell in which the candidate mobile terminal will camp.

[0058] Figure 1 This is a flowchart of a method for determining the cell where a mobile terminal is stationed, provided in an embodiment of the present invention. Figure 1 As shown, the processing steps of this method include:

[0059] Step 101: The indoor network device determines the edge mobile terminal and the corresponding outdoor cell based on the signal measurement information of the indoor mobile terminal accessing the indoor cell. The indoor network device can be implemented as a Building Baseband Unit (BBU). Figure 2 This is a schematic diagram illustrating a scenario for a method to determine the cell where a mobile terminal is stationed, as provided in an embodiment of the present invention. Figure 2 As shown, the indoor area is completely covered by the indoor cell, and the left edge of the indoor cell is simultaneously covered by the outdoor cell. Therefore, the first and second mobile terminals located at the indoor edge can simultaneously detect the communication signals of both the indoor and outdoor cells. At this time, both the first and second mobile terminals are accessing indoor cells. Subsequently, the indoor BBU can determine the first signal quality between the indoor mobile terminal and the indoor cell, and the second signal quality between the indoor mobile terminal and the outdoor cell, based on the signal measurement information of the mobile terminals (first, second, third, and fourth mobile terminals) accessing the indoor cell. Then, indoor mobile terminals whose difference between the first and second signal qualities is less than or equal to a first threshold are identified as edge mobile terminals. Optionally, the signal measurement information can be actively reported by the mobile terminals to the indoor network equipment at fixed time intervals.

[0060] Step 102: The indoor network device sends a first request to the outdoor network device corresponding to the outdoor cell, so that the outdoor network device sends the network resource information of the candidate mobile terminal to the indoor network device according to the first request. The candidate mobile terminal is a mobile terminal that accesses the outdoor cell and whose adjacent cell is an indoor cell.

[0061] In some embodiments, the outdoor network device can be implemented as a BBU. Optionally, the indoor BBU and the outdoor BBU can be configured in the same data center (Central Office, CO) room and connected through a network switch to achieve low-latency, high-speed communication between the indoor BBU and the outdoor BBU.

[0062] Step 103: The outdoor network device receives the first request sent by the indoor network device.

[0063] Step 104: Based on the first request, the outdoor network device identifies mobile terminals whose adjacent cells are indoor cells from among the mobile terminals accessing the outdoor cell as candidate mobile terminals. For example, Figure 2 As shown, only mobile terminals located at the edge of an indoor cell can simultaneously detect communication signals from both the indoor and outdoor cells. Mobile terminals located outdoors can only detect signals from the outdoor cell and cannot detect communication signals from the indoor cell. In other words, only mobile terminals located indoors and connected to an outdoor cell can have adjacent indoor cells.

[0064] Step 105: The outdoor network device sends the network resource information of the candidate mobile terminals to the indoor network device. Upon receiving the first request from the indoor network device, the outdoor network device can proactively send network resource information that meets the candidate mobile terminal criteria to the indoor network device at fixed time intervals, or the indoor network device can proactively obtain network resource information that meets the candidate mobile terminal criteria from the outdoor network device at fixed time intervals. For example, after receiving the first request, the outdoor network device can send the network resource information of the candidate mobile terminals identified within a 10-solt interval to the indoor network device. Optionally, the time interval can be optimized according to the configuration parameters of the wireless tuning. The network resource information refers to the network resources allocated to the mobile terminal, such as the number of Physical Resource Blocks (PRBs), Modulation and Coding Scheme (MCS), Reference Signal Receiving Power (RSRP), and Spectrum Effectiveness (Se).

[0065] Step 106: The indoor network device receives network resource information of candidate mobile terminals sent by the outdoor network device.

[0066] Step 107: The indoor network device determines the first network quality of the indoor cell and the second network quality of the indoor cell after the candidate mobile terminal accesses the indoor cell based on the network resource information of the edge mobile terminal and the candidate mobile terminal.

[0067] The process involves several steps. First, network quality information for each edge mobile terminal and the average network quality information for all edge mobile terminals are determined based on their network resource information. Then, network quality information for each candidate mobile terminal and the average network quality information for all candidate mobile terminals are determined based on their network resource information. Next, a first spectral efficiency is determined based on the network quality information of the edge mobile terminals and the average network quality information for all edge mobile terminals. A second spectral efficiency is then determined based on the network quality information of each candidate mobile terminal, the average network quality information for all candidate mobile terminals, and the network quality information of each edge mobile terminal and the average network quality information for all edge mobile terminals. Finally, a first network quality is determined based on the first spectral efficiency, and a second network quality is determined based on the second spectral efficiency. The first spectral efficiency is the average spectral efficiency of the edge mobile terminals before the candidate mobile terminal accesses the indoor cell. The second spectral efficiency is the average spectral efficiency between the edge mobile terminal and the candidate mobile terminal after the candidate mobile terminal accesses the indoor cell.

[0068] Step 108: If the second network quality is greater than the first network quality, the indoor network device determines the candidate mobile terminal's camping cell as an indoor cell. Optionally, if the second network quality is less than or equal to the first network quality, the candidate mobile terminal's camping cell remains unchanged; that is, the candidate mobile terminal's camping cell is determined to be an outdoor cell. For example, there are three edge mobile terminals in the indoor cell: edge mobile terminal A, edge mobile terminal B, and edge mobile terminal C. There is one candidate mobile terminal, candidate mobile terminal A. The average spectral efficiency of the three edge mobile terminals in the current indoor cell is 50 (first spectral efficiency). When determining the camping cell for candidate mobile terminal A, the average spectral efficiency between the absorbed candidate mobile terminal A and the three edge mobile terminals (a total of four mobile terminals) is calculated to be 54 (second spectral efficiency). Therefore, absorbing candidate mobile terminal A will improve the spectral efficiency of the mobile terminals in the indoor cell, and thus the camping cell for candidate mobile terminal A is determined to be an indoor cell.

[0069] In some embodiments, the cell for a candidate mobile terminal to camp on can also be determined based on the load conditions of both the indoor and outdoor cells. That is, the cell for the candidate mobile terminal to camp on is determined based on the spectral efficiency of the remaining mobile terminals in the outdoor cell after the candidate mobile terminal accesses the indoor cell, and the spectral efficiency of the mobile terminals within the indoor cell. The specific calculation steps are as follows: The network quality information of each candidate mobile terminal is calculated based on its network resource information, including the following parameters: PRB. 宏,i MCS 宏,i RSRP 宏,宏,i RSRP 宏,室,I ΔRSRP 宏,iAmong them, PRB 宏,i This represents the ratio between the number of PRBs occupied by each candidate mobile terminal and the number of PRBs owned by the outdoor cell. Specifically, since the outdoor network equipment collects network resource information of candidate mobile terminals at fixed time intervals (e.g., a first time interval), the number of different PRBs occupied by the candidate mobile terminal within the first time interval can be divided by the first time interval to obtain the average number of PRBs occupied by the candidate mobile terminal within the fixed time interval. Then, this average number of PRBs is compared with the number of PRBs owned by the outdoor cell to obtain the PRB. 宏,i MCS 宏,i The average MCS value for each candidate mobile terminal within the first time interval is obtained. RSRP 宏,宏,i The RSRP values ​​for outdoor cells measured by each candidate mobile terminal are obtained. 宏,室,I The RSRP values ​​for indoor cells measured by each candidate mobile terminal are taken. ΔRSRP 宏,i RSRP for each candidate mobile terminal 宏,室,I With RSRP 宏,室,I The difference between them. Then, based on the network quality information of each candidate mobile terminal, the average network quality information of all edge mobile terminals is calculated. The average network quality information includes the following parameters: PRB 宏 MCS 宏 Se 宏,before Among them, PRB 宏 This is the sum of the number of PRBs occupied by all candidate mobile terminals. MCS 宏 This is the average MCS of all candidate mobile terminals, i.e., the MCS of all candidate mobile terminals. 宏,i The sum of these is then divided by the number of candidate mobile terminals. 宏,before This represents the average spectral efficiency of all candidate mobile terminals.

[0070] Using the same method described above, the ratio between the number of PRBs occupied by each edge mobile terminal and the indoor cell can be calculated based on the network resources of the edge mobile terminal (denoted as PRB). 室,j The sum of the number of PRBs occupied by edge mobile terminals (denoted as PRB) 室 The MCS values ​​of each edge mobile terminal (denoted as MCS) 室,j The PSRP value of the outdoor cell measured by each edge mobile terminal (denoted as RSRP) 室,宏,j The RSRP values ​​of indoor cells measured by each edge mobile terminal (denoted as RSRP) 室,宏,j ), and RSRP of each edge mobile terminal 室,宏,j With RSRP 室,室,j The difference between them (denoted as ΔRSRP) 室,jThe average spectral efficiency of all edge mobile terminals (denoted as Se) 室,before Then, the interference ratio of each candidate mobile terminal to the edge mobile terminal is calculated according to the following formula.

[0071]

[0072] Where, ρ 宏 ρ is the interference impact factor of the outdoor cell. 室 denoted as the interference impact factor of the indoor cell, N0 is the noise floor, M is the number of candidate mobile terminals, and N is the number of edge mobile terminals.

[0073] Next, the average MCS of the indoor cells is calculated: MCS 室,avg,before =Average(MCS) 室,j ); Average SINR of indoor cells: SINR 室,avg,before =MCS2SINR(MCS 室,avg,before ), where MCS2SINR means: converting MCS to SINR; SINR after receiving candidate mobile terminal i in an indoor cell: SINR 室,avg,after,i =SINR 室,avg,before -Lin2dB(1-R i The SINR unit is converted to dB for calculation, where Lin2dB is used. Then, candidate mobile terminals are sorted from highest to lowest based on their interference impact percentage. The SINR of edge mobile terminals is calculated after receiving the first m (m is less than or equal to the total number of candidate mobile terminals) candidate mobile terminals in the indoor cell. And the MCS of the edge mobile terminal after receiving the first m candidate mobile terminals in the indoor cell: MCS 室,avg,after =SINR2MCS(SINR) 室,avg,after ).

[0074] Then, the MCS (Multi-Segment Comparison) of each candidate mobile terminal after accessing the indoor cell is calculated: MCS 宏,驻留室内 =MCS 室,avg,after *(RSRP macro) 宏,室 Mean / RSRP 室,室 (mean)*ρ tx Among them, RSRP 宏,室 The mean is the RSRP of all candidate mobile terminals. 宏,室 The average value of RSRP 室,室 The mean is the RSRP of all candidate mobile terminals. 宏,室 The average value of ρ. tx The MCS impact factor after switching from 64T / 32T to an indoor distribution station.

[0075] Then, the overall spectral efficiency of the edge mobile terminals after m candidate mobile terminals access the indoor cell is calculated according to the following formula.

[0076] Se 宏,after =MCS 室,avg,after *(PRB 室 *N / (N+m))+MCS 宏,驻留室内 *(PRB 室 *m / (N+m). Where N is the number of edge mobile terminals.

[0077] Then, the overall spectral efficiency of the candidate mobile terminals after they access the indoor cell is calculated according to the following formula.

[0078] Se 宏,after =MCS 宏,after *PRB 宏 Among them, MCS 宏,after Let m be the average MCS of the remaining mobile terminals in the outdoor cell after m candidate mobile terminals have accessed the indoor cell.

[0079] Then Se will be satisfied 室,after +Se 宏,after >Se 室,before +Se 宏,before The candidate mobile terminals were identified as effective terminals for improving spectrum efficiency. Figure 3 A waveform diagram illustrating spectral efficiency provided in an embodiment of the present invention, as shown below. Figure 3 As shown, with the increase in the number of mobile terminals accessing the indoor cell, the spectral efficiency of each mobile terminal within the indoor cell first increases and then decreases. The MCS (Multi-Segment Compatibility) of each mobile terminal increases with the increase in the number of mobile terminals. The number of PRBs (Programmable Node Blocks) occupied by each mobile terminal decreases with the increase in the number of mobile terminals. Therefore, by performing iterative calculations to obtain the set of mobile terminals that effectively enhance the spectrum, as many candidate mobile terminals as possible can be accessed to the indoor cell, thereby maximizing the spectral efficiency of mobile terminals within the indoor cell, improving network quality, and enhancing the user experience of mobile terminals within the indoor cell.

[0080] After identifying a candidate mobile terminal that is camped in an indoor cell, the indoor network device can initiate a cell handover procedure for the candidate terminal to the outdoor network device. Figure 4 A flowchart of another method for determining the mobile terminal's camp cell provided in an embodiment of the present invention is shown below. Figure 4 As shown, the processing steps of this method include:

[0081] Step 401: The indoor network device sends a list of candidate mobile terminals that are camped in the indoor cell to the corresponding outdoor network device, so that the outdoor network device can send a cell handover instruction to the candidate mobile terminals according to the list of candidate mobile terminals. The cell handover instruction is used to instruct the candidate mobile terminals to access the indoor cell from the outdoor cell.

[0082] Step 402: The outdoor network device receives the list of candidate mobile terminals sent by the indoor network device.

[0083] Step 403: The outdoor network device sends a cell handover instruction to the candidate mobile terminals in the candidate mobile terminal list, enabling the candidate mobile terminals to access the indoor cell from the outdoor cell according to the cell handover instruction. The outdoor network device can trigger the cell handover by sending control signaling to the mobile terminals in the list. Optionally, the outdoor network device can also modify the cellIndividualOffset (CIO) parameter of the candidate mobile terminals to enable them to access the indoor cell from the outdoor cell. CIO is a parameter between two cells; a larger CIO value makes it easier to hand over from the current cell to a neighboring cell, thus affecting the frequency of handovers between adjacent cells. Specifically, the outdoor network device sends a larger CIO value to the candidate mobile terminals in the list to lower the cell handover threshold, making it easier for the candidate mobile terminals to hand over from the outdoor cell to a neighboring indoor cell.

[0084] Step 404: After detecting that a candidate mobile terminal has accessed the indoor cell, the indoor network device sends a cell camping instruction to the candidate mobile terminal to make it camp on the indoor cell. This cell camping instruction can be implemented by changing the CIO value. Specifically, the indoor network device can send a smaller CIO value to the candidate mobile terminal accessing the indoor cell to increase its cell handover threshold, thereby achieving the goal of keeping the candidate mobile terminal camped on the indoor cell.

[0085] In this embodiment of the invention, the spectral efficiency of mobile terminals in indoor and outdoor cells is calculated based on basic information such as the interference factor caused by outdoor beams, the load levels of both indoor and outdoor cells, and the RSRP of both. If absorbing a candidate mobile terminal into an indoor cell improves the overall spectral efficiency of both cells, then the candidate mobile terminal is incorporated into the indoor cell. This improves the user experience of mobile terminals located at the edge of indoor cells.

[0086] Corresponding to the above method for determining the mobile terminal's designated cell, this embodiment of the invention provides a structural diagram of an indoor network device, as shown below. Figure 5As shown, the device includes a first processing module 501 and a first communication module 502.

[0087] The first processing module 501 is used to determine the edge mobile terminal and the corresponding outdoor cell based on the signal measurement information of the indoor mobile terminal accessing the indoor cell.

[0088] The first communication module 502 is used to send a first request to the outdoor network device corresponding to the outdoor cell, so that the outdoor network device sends the network resource information of the candidate mobile terminal to the indoor network device according to the first request. The candidate mobile terminal is a mobile terminal that accesses the outdoor cell and whose adjacent cell is an indoor cell.

[0089] The first communication module 502 is also used to receive network resource information of candidate mobile terminals sent by outdoor network equipment.

[0090] The first processing module 501 is further configured to determine the first network quality of the indoor cell and the second network quality of the indoor cell after the candidate mobile terminal accesses the indoor cell based on the network resource information of the edge mobile terminal and the candidate mobile terminal.

[0091] The first processing module 501 is further configured to determine the candidate mobile terminal's camping cell as an indoor cell if the second network quality is greater than the first network quality.
