Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is an application scenario provided in an embodiment of the present invention. As shown in fig. 1, a plurality of base stations 101 are disposed along a high-speed rail 102, and the base stations 101 may be divided into a plurality of physical cells (sectors), and as shown in fig. 1, the base stations 101 may be divided into three physical cells, such as A, B and C. When the idle state user terminal and the service state user terminal connected with the physical cell C move from the area covered by the physical cell C of the base station to the area covered by the physical cell B of the base station, the idle state user terminal and the service state user terminal can be reselected or switched from the physical cell C to the physical cell B. The base stations along the high-speed rail may use single carrier frequencies in different frequency bands, for example, may use carrier frequencies in the L1800 frequency band. Of course, in order to expand the capacity of the base station 101, a dual-band carrier networking mode or a multi-band carrier networking mode may be adopted, and in combination with the above-mentioned example of a single carrier frequency, if dual-carrier networking is adopted, a carrier frequency in the L2100 frequency band may be added on the basis of the original carrier frequency in the L1800 frequency band, and a dual-carrier networking mode in the L1800 frequency band and the L2100 frequency band is adopted. Optionally, for the dual carrier frequency networking mode, it is equivalent to divide each physical cell into two logical cells, that is, the logical cells of different carrier frequencies occupy the same area range of the physical cell. For example, the physical cell C includes a first band cell of the L1800 band and a second band cell of the L2100 band.
In a specific communication process, a user terminal held by a high-speed rail passenger is a high-speed user terminal, and a terminal held by a user other than the high-speed rail passenger is a low-speed user terminal. When the high-speed user terminals advance at high speed along the high-speed railway line 102 along with the train, the high-speed user terminals can reselect or switch to cells of different base stations along the line at different positions according to the neighboring cell relation of each cell of the base station 101 and parameters such as reselection parameters or switching parameters. However, in this process, although the capacity of each base station 101 along the high-speed railway line 102 is increased through spread spectrum, and the communication experience of the high-speed user is improved to a certain extent, the low-speed user terminal may also encroach on network resources, so that the communication experience of the high-speed user is reduced, and the user perception of the high-speed user cannot be reasonably measured because the high-speed user and the low-speed user use the network in a mixed manner. Although the prior art determines the moving speed of each user terminal by signaling data transmitted and received between the high-speed user terminal and the low-speed user terminal and the base station 101 to distinguish the high-speed user terminal from the low-speed user terminal, the separation effect achieved by only determining the moving speed is not complete, as shown in fig. 2, all mobile phones moving at high and low speeds are initially loaded on an L2100 carrier layer for use, and layered loading of the high and low-speed mobile phones is achieved by redirecting and migrating the low-speed users to an L1800 carrier layer. In the method, because a base station covering a high-speed rail line is a certain distance away from a rail, and the coverage direction of the base station and a mobile phone service in a high-speed rail carriage forms a certain included angle with a train, the calculated speed is actually the speed in the connecting line direction of the base station and the mobile phone, is lower than the actual running speed of the train, and has a certain error. In addition, the moving speed is finally judged when the moving speed of the high-speed rail calculated within a period of time reaches a certain number of times, so that the mobile phone migration rate is really about 60% at present under the influence of the processing capacity of the base station. That is, only 60% of the low-speed ues can be separated from the high-speed and low-speed ues, and another 60% of the low-speed ues are still mixed with the low-speed ues. Each base station 101 cannot guarantee a good separation effect. Based on the method, the separation method for the high-speed user and the low-speed user is provided, and thoroughness and effectiveness of separation of the high-speed user and the low-speed user are improved.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a flowchart illustrating a method for separating high-speed and low-speed users according to another embodiment of the present invention.
As shown in fig. 3, the method includes:
301. configuring reselection parameters of a first frequency band cell of a first base station and a second frequency band cell of the first base station so as to enable an idle user terminal of the first base station to preferentially reside in the first frequency band cell of the first base station; the idle user terminal comprises a high-speed user terminal and a low-speed user terminal.
In practical applications, the execution subject of this embodiment may be a terminal device or a server connected to each base station.
In this embodiment, the first base station is a base station that is arranged in an area where user separation is required and has at least two carrier frequencies, for example, the first base station may be a base station that is arranged along a high-speed rail line, and the base station may adopt a dual-carrier networking mode, specifically, the dual-carrier networking mode may adopt an L1800 frequency band and an L2100 frequency band.
In this embodiment, the first frequency band cell and the second frequency band cell have different carrier frequencies. The first band cell may include a plurality of logical cells having the same carrier frequency. For example, as shown in fig. 1, it is assumed that a dual-carrier networking manner of an L1800 frequency band and an L2100 frequency band is adopted in the base station 101, and then each physical cell (A, B and C) of the base station 101 corresponds to a logical cell of the L1800 frequency band and a logical cell of the L2100 frequency band. That is, the base station 101 includes 3L 1800 band logical cells and 3L 2100 band logical cells. If the first frequency band is an L1800 frequency band and the second frequency band is an L2100 frequency band, the first frequency band cell and the second frequency band cell both include 3 logical cells.
The high-speed user terminal may be a user terminal that moves at a high speed, for example, a mobile terminal that is held by a passenger on a high-speed train moving at a high speed. The low-speed user terminal may be a user terminal that moves at a low speed, for example, a mobile terminal held by a user outside a high-speed train. Here, the high speed and the low speed can be distinguished by a preset speed per hour, for example, a speed of 400 km/h is used as the distinguishing speed, a speed higher than the distinguishing speed is a high-speed user, and a speed lower than the distinguishing speed is a low-speed user.
Specifically, taking a dual-carrier networking mode in which the base station employs an L1800 frequency band and an L2100 frequency band as an example, considering that the L2100 frequency band is a newly added frequency band carrier, the signal is relatively clean, the interference in the network is small, and the signal quality is obviously better than that of the cell of the L1800 frequency band carrier. Therefore, the method of this embodiment can separate the high speed ue into cells of the L2100 band carrier, and separate the low speed ue into cells of the L1800 band carrier. Firstly, all idle user terminals reside in an L1800 frequency band cell (a first frequency band cell) by setting reselection parameters. Next, the neighboring cell relationship between each cell of the first base station and each cell of the second base station is adjusted, so that a high-speed ue moving at a high speed in the service-state ue can be switched from the L1800 band cell of the first base station (first band cell) to the second band cell of an adjacent base station (e.g., a second base station having an overlapping coverage area with the first base station) during cell switching, and the service-state ue is prohibited from being switched from the L1800 band cell of the first base station to the L2100 band cell (second band cell). That is to say, the high-speed user is gradually switched from the L1800 frequency band to the L2100 frequency band, and the low-speed user is always in the L1800 frequency band cell of the base station, thereby realizing the separation of the high-speed user and the low-speed user.
Optionally, the configuring the reselection parameters of the first frequency band cell of the first base station and the second frequency band cell of the first base station includes:
and configuring the reselection priority of the first frequency band cell of the first base station to be higher than the reselection priority of the second frequency band cell of the first base station, so that the idle user of the first base station preferentially resides in the first frequency band cell of the first base station.
Specifically, the reselection priority of the first frequency band cell may be configured as the highest priority 7, and the reselection priority of the second near-end cell may be configured as any level less than 7, for example, the second highest priority 6.
Optionally, the configuring the reselection parameters of the first frequency band cell of the first base station and the second frequency band cell of the first base station includes:
and reducing the reselection threshold of the first frequency band cell by a preset step length until idle user terminals with a preset proportion reside in the first frequency band cell.
Specifically, the preset ratio may be set according to actual requirements, and the maximum ratio may be set to 100%, that is, all idle users reside in the first frequency band cell. To achieve the best separation. Of course, the ratio can be adjusted down appropriately to accommodate the loading capability of the base station.
302. Adjusting the adjacent cell relation between a first frequency band cell of a first base station and a second frequency band cell of the first base station and a second base station respectively, and configuring switching parameters of the first frequency band cell and the second frequency band cell of the second base station, so that a low-speed user terminal preferentially residing in the first frequency band cell of the first base station cannot be switched to the second frequency band cell of the second base station, and a high-speed user terminal preferentially residing in the first frequency band cell of the first base station is switched to the second frequency band cell of the second base station; the first base station and the second base station are adjacent base stations.
In this embodiment, the second base station is a neighboring base station of the first base station, where the neighboring base station refers to a base station having an overlapping coverage area between two base stations. Here, the neighboring base station is a broad concept and is not limited to being physically adjacent. For example, if base station 1, base station 2, and base station 3 are sequentially arranged in one direction, and usually, overlapping coverage areas exist between base station 1 and base station 2, then base station 2 and base station 2 are neighboring base stations, and if overlapping coverage areas also exist between base station 1 and base station 3, then base station 3 and base station 1 are also neighboring base stations.
Optionally, adjusting the neighboring cell relationship between the first frequency band cell of the first base station and the second frequency band cells of the first base station and the second base station respectively includes:
and canceling the adjacent cell relation between the first frequency band cell of the first base station and the second frequency band cell of the first base station, and establishing the adjacent cell relation between the first frequency band cell of the first base station and the second frequency band cell of the second base station.
Optionally, canceling the neighboring cell relationship between the first frequency band cell of the first base station and the second frequency band cell of the first base station, and establishing the neighboring cell relationship between the first frequency band cell of the first base station and the second frequency band cell of the second base station includes:
deleting the second frequency band cell of the first base station from a neighbor cell list of the first frequency band cell of the first base station;
and adding the second frequency band cell of the second base station into the neighbor list of the first frequency band cell of the first base station.
In this embodiment, the handover parameter includes a handover threshold. The terminal connected with the two cells with the adjacent cell relation can realize switching by setting the switching threshold. Specifically, the method for setting the switching threshold belongs to the prior art, and is not described herein again.
303. And judging the user terminal with the moving speed lower than a preset threshold value in all the user terminals residing in the second frequency band cell as a low-speed user terminal, and switching the low-speed user terminal to the first frequency band cell.
Optionally, before determining, as the low-speed ue, the ue whose moving speed is lower than the preset threshold and switching the low-speed ue to the first frequency band, the method includes: the cell acquires an uplink frequency deviation value of each user terminal residing in the second frequency band cell; and determining the moving speed of the user terminal according to the uplink frequency deviation value through a Doppler formula.
Specifically, taking the user terminal as a mobile phone as an example, the step 303 is illustrated, and the base station may analyze the received uplink frequency offset (uplink direction) value of the mobile phone, and then may analyze the mobile phone moving speed (i.e. the train moving speed) corresponding to the current frequency offset according to the doppler formula, so as to determine that the mobile phone with low speed may be moved to a specific network base station cell, and the mobile phone moving at high speed in the carriage may independently occupy different base station cell resources, thereby implementing that the mobile phone with high speed and low speed uses different base station network resources, and implementing separation of the mobile phone with high speed and low speed, and playing a role of protecting the mobile phone with high speed from using network resources. After the preliminary separation of step 301 to step 302 is performed, the further separation of step 303 is performed, so that the high-speed and low-speed user terminals can be completely separated, and the separation effectiveness is improved.
In the method for separating high-speed and low-speed users provided in this embodiment, by configuring reselection parameters of a first frequency band cell of a first base station and a second frequency band cell of the first base station, an idle user terminal of the first base station is preferentially camped in the first frequency band cell of the first base station; the idle user terminal comprises a high-speed user terminal and a low-speed user terminal; adjusting the adjacent cell relation between a first frequency band cell of a first base station and a second frequency band cell of the first base station and a second base station respectively, and configuring switching parameters of the first frequency band cell and the second frequency band cell of the second base station, so that a low-speed user terminal preferentially residing in the first frequency band cell of the first base station cannot be switched to the second frequency band cell of the second base station, and a high-speed user terminal preferentially residing in the first frequency band cell of the first base station is switched to the second frequency band cell of the second base station; and the first base station and the second base station are adjacent base stations, the user terminal which is resident in the second frequency band cell and has the moving speed lower than the preset threshold value is judged as the low-speed user terminal, and the low-speed user terminal is switched to the first frequency band cell. The method of the embodiment can improve the thoroughness and effectiveness of separation of the high-speed user and the low-speed user.
Fig. 4 is a flowchart illustrating a method for separating high-speed and low-speed users according to another embodiment of the present invention. As shown in fig. 4, on the basis of the foregoing embodiment, in this embodiment, the neighboring cell relationship between the second frequency band cells of the neighboring base stations is adjusted, so that the high-speed user stripped to the second frequency band cell can perform handover on the same-frequency cell during the moving process. The method comprises the following steps:
401. configuring reselection parameters of a first frequency band cell of a first base station and a second frequency band cell of the first base station so as to enable an idle user terminal of the first base station to preferentially reside in the first frequency band cell of the first base station; the idle user terminal comprises a high-speed user terminal and a low-speed user terminal.
402. Adjusting the adjacent cell relation between a first frequency band cell of a first base station and a second frequency band cell of the first base station and a second base station respectively, and configuring switching parameters of the first frequency band cell and the second frequency band cell of the second base station, so that a low-speed user terminal preferentially residing in the first frequency band cell of the first base station cannot be switched to the second frequency band cell of the second base station, and a high-speed user terminal preferentially residing in the first frequency band cell of the first base station is switched to the second frequency band cell of the second base station; the first base station and the second base station are adjacent base stations.

In this embodiment, in order to enable a high-speed user in a service state of a second frequency band cell of a first base station to switch on a same-frequency cell in a moving process, that is, to remain on the second frequency band cell and keep a separated state from a low-speed user of the first frequency band cell, the adjacent relationship between the first base station and the second frequency band cell of the second base station may be set. For a specific switching method, reference may be made to the description of step 302, which is not described herein again.

The first base station 501 and the second base station 502 are neighbouring base stations arranged along a high-speed railway line 503. In a specific implementation process, in step a, idle ues (e.g., all idle ues) in a preset proportion reside in the L1800 frequency band cell by setting reselection parameters of the L1800 cell and the L2100 cell of the first base station 501. Step b, canceling the neighboring cell relationship between the L1800 cell and the L2100 cell of the first base station 501, so that the idle user residing in the L1800 cell cannot be switched to the L2100 cell in the base station after being converted into a service state. And c, establishing a neighboring cell relation between the L1800 cell of the first base station 501 and the L2100 cell of the second base station 502, so that the high-speed user terminal held by the high-speed rail passenger can be switched to the L2100 cell of the second base station after the train moves from left to right along the high-speed rail line 503 at a high speed to perform a second base station coverage area. Step d, establishing a neighboring cell relationship between the L2100 cell of the first base station 501 and the L2100 cell of the second base station 502, so that the service-state high-speed ue of the L2100 cell of the first base station 501 can be switched to the L2100 cell of the second base station 502 after the train moves to the coverage area of the L2100 cell of the second base station 502 at a high speed, thereby further ensuring the separation of the high-speed ue and the low-speed ue.
It should be noted that, in this embodiment, the execution order of the parameter settings of steps a-d is not limited. That is, the execution sequence of steps 401 to 403 is not limited, and step 403 may be performed after step 401 to step 402, before step 401, or in parallel.
