The inventor of the present disclosure finds that, in the related art, when a plurality of users are under the coverage of a beam of the same base station and a base station of an adjacent cell is relatively idle, since a difference value between an RSRP of the base station of the adjacent cell and an RSRP of a current base station does not exceed a handover threshold value, a terminal cannot be actively handed over to the adjacent cell, thereby affecting network capacity of the terminal.
In view of this, embodiments of the present disclosure provide a method for a terminal to switch a cell, thereby facilitating the terminal to switch to an adjacent cell.
Fig. 1 is a flow chart illustrating a method for a terminal to switch cells in accordance with some embodiments of the present disclosure. Fig. 2 is a schematic structural diagram illustrating a system for a terminal to switch cells according to some embodiments of the present disclosure. The following describes in detail a flow of a method for a terminal to switch cells according to some embodiments of the present disclosure with reference to fig. 1 and 2.
As shown in fig. 1, in step S102, resource information requested to be allocated by a plurality of terminals and Measurement Report (Measurement Report) information uploaded by the plurality of terminals are received, wherein the plurality of terminals are covered by a first beam of a current base station, and the Measurement Report information includes: first RSRP information of a current base station under the first beam and second RSRP information of base stations of adjacent cells of a cell where the current base station is located under a second beam. For example, the resource information may include the number of resources. Here, the second beam is different from the first beam.
For example, in a 5G network, the base stations may emit different beams. For example, as shown in fig. 2, a plurality of terminals 1, 2, and 3 are covered by a first beam of a base station (i.e., current base station) 211 of a current cell 210. The plurality of terminals 1 to 3 may measure first RSRP information of the current base station 211 in the first beam and second RSRP information of the base station 221 of the neighboring cell 220 in the second beam. The plurality of terminals 1 to 3 upload a measurement report to the current base station 211, the measurement report including first RSRP information of the current base station 211 in a first beam and second RSRP information of the base station 221 of the neighboring cell in a second beam. In addition, the plurality of terminals also transmit resource information, each of which requests allocation, to the current base station 211. Therefore, the current base station 211 receives the resource information requested to be allocated by the plurality of terminals 1 to 3 and the measurement report information uploaded by the plurality of terminals.
Returning to fig. 1, in step S104, in a case that the resource information requested to be allocated by the plurality of terminals is greater than the resource information that can be allocated by the current base station under the first beam, cell handover information is sent to at least one of the plurality of terminals according to the first RSRP information and the second RSRP information. Here, the cell handover information includes base station information of a neighboring cell to which the terminal needs to be handed over.
For example, as shown in fig. 2, if the current base station 211 determines that the resource information requested to be allocated by the plurality of terminals 1 to 3 is greater than the resource information that can be allocated by the current base station 211 under the first beam, the current base station 211 sends cell handover information to at least one terminal (for example, terminal 1) of the plurality of terminals according to the first RSRP information and the second RSRP information. The cell handover information includes base station information of the neighboring cell 220 to which the terminal needs to be handed over. For example, the base station information may include address information of the base station 221, and the like.
In this way, the at least one terminal (e.g., terminal 1) receives the cell switching information and switches to the base station 221 of the neighboring cell according to the base station information of the neighboring cell 220. After the handover to the base station 221 of the neighboring cell, the at least one terminal is covered by the second beam of the base station 221 of the neighboring cell.
To this end, methods for a terminal to switch cells according to some embodiments of the present disclosure are provided. The method comprises the following steps: receiving resource information requested to be allocated by a plurality of terminals and measurement report information uploaded by the plurality of terminals, wherein the plurality of terminals are covered by a first beam of a current base station, and the measurement report information comprises: first RSRP information of a current base station under the first wave beam and second RSRP information of base stations of adjacent cells of a cell where the current base station is located under a second wave beam, wherein the second wave beam is different from the first wave beam; and sending cell switching information to at least one terminal in the plurality of terminals according to the first RSRP information and the second RSRP information under the condition that the resource information requested to be allocated by the plurality of terminals is larger than the resource information which can be allocated by the current base station under the first beam. The cell switching information includes base station information of a neighboring cell to which the terminal needs to be switched. And after receiving the cell switching information, the at least one terminal switches to the base station of the adjacent cell according to the base station information of the adjacent cell and is covered by the second wave beam of the base station of the adjacent cell after being switched to the base station of the adjacent cell. Therefore, the terminal can be switched to the idle adjacent cell under the condition that the current base station can not meet the resource request. Compared with the related technology, the method is more convenient for the terminal to switch to the adjacent cell, thereby being beneficial to improving the network capacity of the terminal.
In some embodiments, the method may further comprise: and under the condition that the resource information requested to be allocated by the plurality of terminals is less than or equal to the resource information allocable by the current base station under the first beam, not sending the cell switching information to the plurality of terminals. That is, when the resources requested to be allocated by the terminal are less than or equal to the resources allocable by the base station, the terminal may remain in the network of the current cell and not perform cell handover.
In some embodiments, the step of sending cell handover information to at least one of the plurality of terminals according to the first RSRP information and the second RSRP information may comprise: and under the condition that the absolute value of the difference value between the second RSRP information and the first RSRP information is smaller than a switching threshold value, sending cell switching information to the at least one terminal. Here, the first RSRP information is RSRP of the current base station in the beam, and the second RSRP information is RSRP of the base station of the neighboring cell in the beam.
That is, in the case that the resource information requested to be allocated by the plurality of terminals is larger than the resource information that can be allocated by the current base station in the first beam, if the resource information is larger than the resource information that can be allocated by the current base station in the first beam
The RSRP of the base station of the neighboring cell-the RSRP of the current base station | < handover threshold, (1) here, | is an absolute value, the current base station sends cell handover information to at least one terminal. This prevents ping-pong handover problems.
For example, if the RSRP of the base station of the neighboring cell is less than the RSRP of the current base station, and | the RSRP of the base station of the neighboring cell — the RSRP of the current base station | ≧ the handover threshold value, it may cause a problem of ping-pong handover that although a certain terminal is handed over from the current base station to the base station of the neighboring cell, the terminal is handed over from the base station of the neighboring cell back to the current base station since the RSRP of the current base station is better. By setting the condition (1), the terminal is switched from the current base station to the base station of the adjacent cell under the condition that the resource information requested to be allocated by the plurality of terminals is greater than the resource information allocable by the current base station under the first beam and the condition (1) is met, so that the problem of ping-pong switching can be prevented.
Through the above condition (1), it can be seen that the above method of the embodiment of the present disclosure is implemented for the terminal to switch the cell when the RSRP of the current base station and the RSRP of the base station of the neighboring cell are not much different.
In other embodiments, the terminal automatically switches to the base station of the neighboring cell when the RSRP of the base station of the neighboring cell — the RSRP of the current base station is greater than or equal to the switching threshold value. This is similar to the related art and will not be described in detail here.
Here, the switching threshold value is a positive value. In some embodiments, the switching threshold may range from 2dB (decibel) to 5 dB. For example, the switching threshold may be 3 dB. Of course, those skilled in the art will appreciate that the range of the handover threshold value is merely exemplary, and the range of the handover threshold value of the embodiments of the present disclosure may not be limited thereto. For example, the switchable threshold value may be determined according to actual needs.
In some embodiments, the method may further comprise: acquiring a first resource utilization rate of a current base station under a first beam and a second resource utilization rate of a base station of an adjacent cell under a second beam; comparing the second resource utilization with the first resource utilization; and if the second resource utilization rate is greater than the first resource utilization rate, no matter whether the resource information requested to be allocated by the plurality of terminals is greater than the resource information allocable by the current base station under the first beam, the cell switching information is not sent to the plurality of terminals. For example, the current base station may obtain resource utilization of the base station of the neighboring cell through the corresponding port, which is a known technology and will not be described in detail.
In this embodiment, when multiple terminals are under the same beam coverage of the current base station, and when the resources requested to be allocated by the multiple terminals are greater than the resources allocable by the base station, but the congestion degree (for example, characterized by the second resource utilization rate) of the neighboring cell is greater than the congestion degree (for example, characterized by the first resource utilization rate) of the current cell, the terminals may remain in the network of the current cell and do not perform handover. This may prevent the terminal from switching to a more congested cell.
Fig. 3 is a flowchart illustrating methods for a terminal to switch cells according to further embodiments of the present disclosure. As shown in fig. 3, the method includes steps S302 to S310.
In step S302, resource information requested to be allocated by a plurality of terminals and measurement report information uploaded by the plurality of terminals are received, and the plurality of terminals are covered by a first beam of a current base station; and acquiring a first resource utilization rate of the current base station under the first beam and a second resource utilization rate of the base station of the adjacent cell under the second beam. The measurement report information includes: the method comprises the steps that first RSRP information of a current base station under a first beam and second RSRP information of base stations of adjacent cells of a cell where the current base station is located under a second beam.
In step S304, the current base station determines whether the second resource utilization rate is greater than the first resource utilization rate. If so, the process advances to step S308; otherwise, the process proceeds to step 306.
In step S306, the current base station determines whether the resource information requested to be allocated by the multiple terminals is greater than the resource information allocable by the current base station under the first beam. If so, the process advances to step S310; otherwise, the process advances to step S308.
In step S308, the current base station does not transmit cell switching information to the terminal.
In step S310, cell handover information is sent to at least one terminal according to the first RSRP information and the second RSRP information. The cell switching information includes base station information of a neighboring cell to which the terminal needs to be switched.
For example, the cell handover information is sent to the at least one terminal in case that an absolute value of a difference between the second RSRP information of the base station of the neighboring cell and the first RSRP information of the current base station is smaller than a handover threshold value.
In the related art, if the absolute value of the difference between the RSRP information of the base station of the neighboring cell and the RSRP information of the current base station is smaller than the handover threshold value, the handover threshold requirement of the related art is not satisfied, that is, the terminal cannot be handed over to the neighboring cell under the condition of the related art. However, according to the method in the embodiment of the present disclosure, when the resource requested to be allocated by the terminal is greater than the resource allocable by the base station, the base station may allow the terminal to switch to an idle neighboring cell without meeting the requirement of the handover threshold of the related art according to the measurement report information reported by the terminal.
In other embodiments, according to the foregoing description, the terminal may automatically switch to the base station of the neighboring cell in case the second RSRP — the first RSRP ≧ the switch threshold value.
To this end, methods for a terminal to switch cells according to further embodiments of the present disclosure are provided. In the method, a plurality of terminals are under the same beam coverage of the base station, and when the resource requested to be allocated by the terminal is larger than the resource allocable by the base station, the base station can allow the terminal to be switched to an idle adjacent cell under the condition that the switching threshold requirement of the related technology is not met according to the measurement report information reported by the terminal. Therefore, the terminal can be switched to the idle adjacent cell under the condition that the current base station can not meet the resource request, and the network capacity of the terminal is improved. In addition, the method can also avoid the problem of terminal ping-pong switching.

The receiving unit 410 is configured to receive resource information requested to be allocated by a plurality of terminals and measurement report information uploaded by the plurality of terminals. The plurality of terminals are covered by a first beam of the current base station. The measurement report information includes: the method comprises the steps that first RSRP information of a current base station under a first beam and second RSRP information of base stations of adjacent cells of a cell where the current base station is located under a second beam. Here, the second beam is different from the first beam.
The determining unit 420 is configured to determine whether resource information requested to be allocated by the multiple terminals is greater than resource information that can be allocated by the current base station in the first beam.
The sending unit 430 is configured to send cell handover information to at least one of the plurality of terminals according to the first RSRP information and the second RSRP information, when the resource information requested to be allocated by the plurality of terminals is greater than the resource information that can be allocated by the current base station in the first beam. The cell switching information includes base station information of a neighboring cell to which the terminal needs to be switched.
And after receiving the cell switching information, the at least one terminal switches to the base station of the adjacent cell according to the base station information of the adjacent cell, and is covered by the second beam of the base station of the adjacent cell after being switched to the base station of the adjacent cell.
To this end, a base station according to some embodiments of the present disclosure is provided. The base station includes: a receiving unit, configured to receive resource information requested to be allocated by multiple terminals and measurement report information uploaded by the multiple terminals, where the multiple terminals are covered by a first beam of a current base station, and the measurement report information includes: first RSRP information of a current base station under a first beam and second RSRP information of base stations of adjacent cells of a cell where the current base station is located under a second beam; a determining unit, configured to determine whether resource information requested to be allocated by the multiple terminals is greater than resource information allocable by a current base station in a first beam; and a sending unit, configured to send cell handover information to at least one of the multiple terminals according to the first RSRP information and the second RSRP information when resource information requested to be allocated by the multiple terminals is greater than resource information allocable by a current base station in the first beam, where the cell handover information includes base station information of a neighboring cell to which the terminal needs to be handed over. And after receiving the cell switching information, the at least one terminal is switched to the base station of the adjacent cell according to the base station information of the adjacent cell and is covered by the second wave beam of the base station of the adjacent cell after being switched to the base station of the adjacent cell. Therefore, the terminal can be switched to the idle adjacent cell under the condition that the current base station can not meet the resource request, and the network capacity of the terminal is improved.
In some embodiments, the sending unit 430 may be configured to send the cell handover information to the at least one terminal if an absolute value of a difference between the second RSRP information and the first RSRP information is less than a handover threshold value.
In some embodiments, the sending unit 430 may be further configured to not send the cell switching information to the plurality of terminals if the resource information requested to be allocated by the plurality of terminals is less than or equal to the resource information that can be allocated by the current base station in the first beam.
In some embodiments, the receiving unit 410 may further be configured to obtain a first resource utilization rate of the current base station itself in the first beam and a second resource utilization rate of the base station of the neighboring cell in the second beam.
