Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, and in particular to a frequency selection method, apparatus, and computer-readable storage medium. Background Technology

[0002] Different frequency bands differ in carrier bandwidth, multi-antenna capability, and duplex mode, resulting in significant variations in energy consumption (both at the base station and terminal sides) and capacity (e.g., user rate, cell rate). When a terminal initiates a service within its designated frequency band, frequency band priority cannot comprehensively consider the differences in power consumption and rate across different bands. Consequently, the terminal cannot simultaneously consider the power consumption and rate performance of different frequency bands after initiating a service. Summary of the Invention

[0003] In view of this, embodiments of the present invention aim to provide a frequency selection method, apparatus, and computer-readable storage medium.

[0004] To achieve the above objectives, the technical solution of this invention is implemented as follows:

[0005] This invention provides a frequency selection method applied to the network side, comprising:

[0006] When the terminal is in a connected state, obtain neighbor cell information;

[0007] Frequency priority is determined based on the power consumption and / or rate in the serving cell information and the neighboring cell information.

[0008] The neighboring cell information includes, but is not limited to, one or more of the following:

[0009] Cell load; maximum number of user flows; maximum number of cell flows; spatial multiplexing ratio; base station full load power consumption; base station real-time power consumption; terminal power consumption; carrier bandwidth; duplex mode; time slot allocation.

[0010] The acquisition of neighboring cell information includes: acquiring the neighboring cell information through the network management side data configuration of the serving cell; or acquiring the neighboring cell information through the interaction information between the serving cell and the neighboring cells.

[0011] The step of determining frequency priority based on the serving cell information and the power consumption in the neighboring cell information includes:

[0012] The power consumption of the base station or terminal is compared based on the serving cell information and the neighboring cell information;

[0013] The cell with the lowest base station or terminal power consumption has the highest frequency priority.

[0014] When determining terminal power consumption, the method further includes:

[0015] The neighbor cell reference signal received power (PRSP) is obtained based on terminal measurements, and the neighbor cell power margin (PHR) is determined based on the neighbor cell RSRP and the terminal power; or...

[0016] The neighboring cell PHR is determined based on the PHR information reported by the terminal; the PHR information carries incremental or absolute information of the neighboring cell PHR.

[0017] The step of determining frequency priority based on the serving cell information and the rates in the neighboring cell information includes:

[0018] Based on the serving cell information and the neighboring cell information, the uplink or downlink peak rates of users in the serving cell and the uplink or downlink peak rates of users in the neighboring cells are determined respectively.

[0020] The cell with the highest maximum available uplink or downlink speed for a user has the highest frequency priority.

[0021] The determination of the user's maximum available uplink or downlink rate includes:

[0022] Without considering multi-user spatial multiplexing, the maximum available uplink or downlink rate for the user = peak uplink or downlink rate * (1 - physical resource block (PRB) utilization rate).

[0023] When considering multi-user spatial multiplexing, the maximum available uplink or downlink rate for the user = uplink or downlink peak rate * (1 - PRB utilization) * spatial multiplexing ratio.

[0024] The step of determining frequency priority based on the serving cell information and the power consumption and rate in the neighboring cell information includes:

[0025] Based on the serving cell information and the neighboring cell information, the retention coefficients corresponding to the serving cell and the neighboring cells are determined respectively;

[0026] Frequency priority is determined based on the dwell coefficient, with the cell having the highest dwell coefficient having the highest frequency priority.

[0027] The determination of the residency coefficients corresponding to the serving cell and neighboring cells includes:

[0028] Based on the serving cell information and the neighboring cell information, the maximum available uplink or downlink rate for users in the serving cell and the maximum available uplink or downlink rate for users in the neighboring cells are determined respectively.

[0029] The dwell coefficient of the corresponding cell is determined based on the power consumption of the serving cell and the neighboring cells and the maximum available uplink or downlink rate of each cell.

[0030] Wherein, the determination of the residency coefficient of the corresponding cell is:

[0031] The cell dwell factor = (power consumption of neighboring cells / power consumption of serving cell) * (maximum available uplink or downlink rate for users of serving cell / maximum available uplink or downlink rate for users of neighboring cells).

[0032] Optionally, the method further includes:

[0033] The frequency priority determined based on power consumption and / or rate is compared with the frequency priority in the Radio Resource Control (RRC) release message. If they do not match, the frequency priority in the RRC release message is replaced with the frequency priority determined based on power consumption and / or rate.

[0034] This invention also provides a frequency selection method where, when the terminal is in an idle state, the serving cell and neighboring cells have the same frequency priority but different frequency bands. The method includes:

[0035] When performing cell reselection, the terminal compares the reference signal received power RSRP of the neighboring cell with a preset threshold;

[0036] If the serving cell is in a low-frequency band and the neighboring cell is in a high-frequency band, and the RSRP of the neighboring cell is greater than a preset threshold, then the serving cell will camp on the high-frequency band corresponding to the neighboring cell; otherwise, it will camp on the low-frequency band corresponding to the serving cell.

[0192] This embodiment proposes a frequency selection method that considers both power consumption and capacity when selecting a frequency.

[0193] Option 1: When the terminal is in idle state, the 700MHz (serving cell) and 2.6GHz (neighboring cell) frequencies have the same priority, and the terminal determines the camping frequency band based on the downlink measurement RSRP.

[0194] Step 1: The terminal performs cell selection or cell reselection;

[0195] Step 2: The terminal measures the downlink RSRP at 2.6GHz and 700MHz, and selects the camping frequency band by measuring the RSRP;

[0196] It is known that the relevant cell selection follows the S criterion, and the cell reselection follows the R criterion. The S criterion for cell selection is designed to ensure the maximum performance of users, while the cell reselection criterion allows the terminal to select a better cell to camp on.

[0197] This embodiment proposes an enhanced cell reselection criterion (R criterion) within the 5G NR band. The relevant R criterion is Mn+Ofn+Ocn-Hys>Ms+Ofs+Ocs+Off. Since the coverage of 700MHz is definitely better than 2.6GHz in the field (low frequency band, 700MHz and 2.6GHz site ratio 1:2), it is highly likely that all users will camp on 700MHz. This embodiment adds a 2.6GHz Mn>-90dBm criterion (this threshold is only for illustration, and the specific value can be configured through network management). That is, as long as the RSRP of the 2.6GHz cell meets the preset threshold, it will camp on 2.6GHz. Only in areas where 2.6GHz coverage is insufficient will the original R criterion be used. The threshold value can be updated according to network planning.

[0198] Option 2: When the terminal is in connected mode, the base station adaptively updates the frequency priorities of 700MHz and 2.6GHz based on neighbor cell information, optimizing user performance through load balancing. The specific solution is as follows:

[0199] Step 1: For the 700MHz cell, acquire information such as the load of neighboring 2.6GHz cells (e.g., PRB or bandwidth utilization), maximum number of user flows, maximum number of cell flows, spatial multiplexing ratio, base station full load power consumption, base station real-time power consumption, terminal power consumption, carrier bandwidth, duplex mode, and time slot allocation (all of this information can be acquired, or only a portion of it can be acquired).

[0200] The above information can be obtained through the network management side data configuration of the 700MHz cell, or through the information exchange between the 700MHz cell and the 2.6GHz cell (for example, the 700MHz cell periodically sends a request to the 2.6GHz cell to obtain the above information).

[0201] Step Two: Based on the information obtained above, the frequency priority of the 700MHz cell and the 2.6GHz cell is calculated. The specific calculation method is as follows:

[0202] 1) Power Consumption Priority: Power consumption can be determined based on either the base station or the terminal. When based on base station power consumption, full-load power consumption or real-time power consumption can be compared. For example, when using full-load power consumption, the frequency with the lowest power consumption (700MHz or 2.6GHz) has the highest priority. When based on terminal power consumption, if the terminal is in idle mode, the base station cannot obtain the terminal's location or uplink power consumption; if the terminal is in connected mode, the terminal power consumption can be determined based on the PHR power margin reported by the terminal. However, in related technologies, the PHR can only report the serving cell power margin. This embodiment proposes the following enhancement scheme:

[0203] Enhanced Neighbor Cell Power Margin Reporting: Neighbor cell PRSP is obtained based on terminal measurements. Neighbor cell PHR is calculated based on neighbor cell RSRP and terminal power. Incremental or absolute PHR information is added to the relevant PHR reporting information, identifying which neighbor cell's PHR value it is. The terminal's power consumption at 700MHz and 2.6GHz is compared, with the frequency of lower power consumption receiving the highest priority.

[0204] 2) Uplink Rate Priority: Based on the obtained information such as the maximum number of streams, time slot allocation, carrier bandwidth, and duplex mode of 2.6GHz users, the peak uplink rate of 2.6GHz users can be calculated. Based on the peak uplink rate of 2.6GHz and the 2.6GHz load (e.g., PRB utilization), the maximum available uplink rate of 2.6GHz users (without considering multi-user spatial multiplexing) can be obtained as: Peak uplink rate * (1 - PRB utilization). When considering multi-user spatial multiplexing, the maximum available uplink rate of a user = Peak uplink rate * (1 - PRB utilization) * Spatial multiplexing ratio. The spatial multiplexing ratio refers to the number of users who can reuse the same network resources. Examples are shown in Tables 1 and 2 below:

[0205]

[0206] Table 1

[0207]

[0208] Table 2

[0209] 3) Downlink rate priority:

[0210] Here, the calculation method for downlink rate priority is similar to that for uplink rate priority, namely: based on the 2.6GHz downlink peak rate and the 2.6GHz load (e.g., PRB utilization), the maximum available downlink rate for 2.6GHz users (without considering multi-user spatial multiplexing) can be calculated as: downlink peak rate * (1 - PRB utilization). When considering multi-user spatial multiplexing, the maximum available downlink rate for users = downlink peak rate * (1 - PRB utilization) * spatial multiplexing ratio.

[0211] 4) Taking into account power consumption and speed: Based on power consumption and the maximum available speed for users, calculate the cell retention factor = (2.6G power consumption / 700MHz power consumption) * (700MHz speed / 2.6G speed). If this value is greater than or equal to 1, the 700MHz band has higher priority; if it is less than 1, the 2.6GHz band has higher priority. Examples are shown in Tables 3 and 4 below:

[0212] Table 3: Example 1 of Frequency Priority Selection Considering Power Consumption and Speed

[0213]

[0214] Table 4: Example 2 of Frequency Priority Selection Considering Power Consumption and Speed

[0215]

[0216] The four frequency priority calculation methods mentioned above can be configured and selected on the network management system.

[0217] Step 3: When the 700MHz cell finds that the frequency priority (denoted as A) obtained by the above algorithm is inconsistent with the dedicated frequency priority (denoted as C) carried in the RRC release message, the dedicated frequency priority is updated to C in the RRC release message.

[0218] The above description only uses the 700MHz and 2.6GHz hybrid network and the algorithm on the 700MHz cell side as an example. This embodiment can be further expanded to more frequency bands and other frequency bands, which will not be described in detail here.

[0219] As can be seen, the embodiments of the present invention determine frequency priority based on power consumption and / or data rate. Considering the significant differences in power consumption capability and user data rate performance among different frequency bands, the present invention achieves optimal performance in terms of power consumption and data rate, reduces operation and maintenance costs, and improves user experience.

[0220] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
