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 a schematic structural diagram of a first embodiment of the cell outage compensation device in the present invention, and as shown in fig. 1, the cell outage compensation device in this embodiment may include: the receiving unit 11 is configured to receive association information of a UE served by a first micro base station, where the association information of the UE includes an identifier of a second base station, and the second base station is a neighboring base station with a largest sum of a Reference signal receiving Power (Reference signal receiving Power, RSRP) and a Cell Selection Bias (Cell Selection Bias, CSB) received by the UE; the detecting unit 12 is configured to detect whether the first micro base station is interrupted; the determining unit 13 is configured to determine, according to the association information of the UE, a base station providing a compensation service for the UE when the detecting unit 12 detects that the first micro base station is interrupted.
In this embodiment, the cell outage compensation device may manage at least one micro base station, the first micro base station in this embodiment is any one of all micro base stations managed by the cell outage compensation device, and the cell outage compensation device may be disposed in a base station (for example, a micro base station or a macro base station), or may be a device independent of the base station.
In this embodiment, the number of UEs served by the first micro base station is at least one, and therefore, the receiving unit 11 may receive the association information of at least one UE sent by the first micro base station, where the association information of each UE includes an identifier of the second base station, the UE may receive the RSRP and the CSB sent by each neighboring base station, the UE may add and compare the RSRP and the CSB of each neighboring base station, and then use the neighboring base station corresponding to the largest sum of the RSRP and the CSB as the second base station. Since the UE is moving and the association information of the UE may also change, the receiving unit 11 may periodically receive the association information of at least one UE sent by the first micro base station, and the association information of the UE received when the current period arrives may cover the association information of the UE received when the previous period arrives. The detecting unit 12 may detect whether the first micro base station is interrupted, where the interruption of the first micro base station has two forms, one is active interruption of the first micro base station, for example, the first micro base station is actively turned off due to policies such as energy saving or adaptive service distribution, and the other is passive interruption of the first micro base station, for example, the first micro base station is interrupted due to hardware failure or insufficient power supply of the first micro base station. When the detecting unit 12 detects that the first micro base station is interrupted, in order to ensure normal operation of the UE service and improve user experience, other normally operating base stations need to be scheduled to provide compensation service for the UE, and the determining unit 13 determines a base station providing compensation service for the UE according to the association information of the UE, that is, a base station providing compensation service for the UE is determined according to the relevant information of the second base station. If the receiving unit 11 periodically receives the association information of the UE sent by the first micro base station, the determining unit 13 determines the base station providing the UE with the compensation service according to the association information of the UE received last by the receiving unit 11 before the interruption of the first micro base station occurs.
For example: the receiving unit 11 receives the association information of three UEs (UE1, UE2 and UE3) transmitted by the first micro base station, when the detecting unit 12 detects that the first micro base station is interrupted, the determining unit 13 determines the base stations providing the compensation service for the three UEs according to the association information of the three UEs, namely, the determining unit 13 determines the base station providing the compensation service for the UE1 according to the association information of the UE1, determines the base station providing the compensation service for the UE2 according to the association information of the UE2, and determines the base station providing the compensation service for the UE3 according to the association information of the UE 3.
In this embodiment, the receiving unit receives the association information of the UE, which is sent by the first micro base station and includes the identifier of the second base station, and then the determining unit determines the neighboring base station providing the compensation service for the UE according to the association information of the UE when the first micro base station is interrupted. Namely, the base station providing compensation service for the UE is determined according to the identifier of the adjacent base station with the maximum sum of the RSRP and the CSB received by the UE, so that the cell interruption compensation corresponding to the micro base station is realized.
In a second embodiment of the cell outage compensation device in the present invention, on the basis of the structure shown in fig. 1, in this embodiment, the association information of the UE received by the receiving unit 11 further includes indication information, where the indication information is used to indicate a type of the second base station; the determining unit 13 is specifically configured to determine, according to the indication information and the identifier of the second base station, a base station that provides a compensation service for the UE. Specifically, the type of the second base station may indicate whether the second base station is a macro base station or a micro base station, and whether the macro base station where the second base station is located is the same as the macro base station where the first micro base station is located. The determining unit 13 may determine the base station providing the UE with the compensation service according to the type of the second base station and the identity of the second base station.
The following describes in detail the cell outage compensation device according to the embodiment of the present invention, how a UE determines a compensation service mode by the cell outage compensation device, and how the cell outage compensation device determines a compensation service mode by another UE similarly.
In a feasible implementation manner, the indication information is first indication information, the first indication information is used for indicating that the second base station is a macro base station, and the second base station is the same as the macro base station where the first micro base station is located, that is, the second base station and the macro base station where the first micro base station is located are the same base station; the determining unit 13 is specifically configured to: and determining a macro base station where the first micro base station is located to provide compensation service for the UE according to the first indication information and the identifier of the second base station. Specifically, the first indication information is used to indicate that the second base station is a macro base station, and the macro base station where the serving base station (first micro base station) of the UE is located is the same as the second base station, for example: the first indication information may be indication information of a single micro base station user, and then the determining unit 13 may determine that a macro base station (i.e., a second base station) where the first micro base station is located provides the UE with the compensation service, and then the macro base station where the first micro base station is located may provide the UE with the compensation service according to a standard that a serving base station of the UE is the macro base station.
It should be noted that, if the first micro base station is located within the coverage of one macro base station, the macro base station may be referred to as the macro base station where the first micro base station is located, and if the first micro base station is located within the coverage of at least two macro base stations, the macro base station where the signal strength received by the first micro base station is the largest may be referred to as the macro base station where the first micro base station is located.
In a second feasible implementation manner, the indication information is second indication information, where the second indication information is used to indicate that the second base station is a macro base station, and the macro base station where the first micro base station is located is different from the second base station; the determining unit 13 is specifically configured to determine, according to the second indication information and the identifier of the second base station, that the macro base station where the first micro base station is located and the second base station provide a compensation service for the UE based on a Coordinated Multiple Points (CoMP) technology. Specifically, the second indication information is used to indicate that the second base station is a macro base station, and the macro base station where the first micro base station is located is different from the second base station, for example: the second indication information may be indication information of a user of an adjacent macro base station, and the determining unit 13 may determine that the macro base station where the first micro base station is located and the second base station provide the UE with the compensation service based on the CoMP technology. It should be noted that, the macro base station where the first micro base station is located and the second base station provide the UE with the compensation service based on the CoMP technology, which may refer to related records of the CoMP technology in the prior art, and details are not described here.
Optionally, the determining unit 13 is further configured to determine that the load of the second base station is less than or equal to a first threshold value before determining, according to the user category of the UE, that the macro base station where the first micro base station is located and the second base station provide the compensation service for the UE based on the CoMP technology. Since the second base station is an adjacent macro base station, before the determining unit 13 determines that the second base station can provide the compensation service for the UE, it needs to determine whether the load of the second base station is greater than a first threshold, where the load of the second base station indicates a utilization rate of network resources of the second base station, if the load of the second base station is greater, it indicates that the available network resources of the second base station are less, if the load of the second base station is less, it indicates that the available network resources of the second base station are more, and if the determining unit 13 determines that the load of the second base station is less than or equal to the first threshold (for example, 0.9), it indicates that the available network resources of the second base station are more, and the second base station can provide the compensation service for the UE, thereby determining that the macro base station where the first micro base station is located and the second base station provide the compensation service for the UE; if the determining unit 13 determines that the load of the second base station is greater than the first threshold, it indicates that the available network resources of the second base station are less, and the second base station cannot provide the UE with the compensation service, and then the procedure is ended. Alternatively, the receiving unit 11 may receive the loads sent by the base stations (the micro base station and the macro base station), and the determining unit 13 may determine the load of the second base station from the received loads of the base stations according to the identifier of the second base station in the association information of the UE.
In a third possible implementation manner, the association information of the UE received by the receiving unit 11 further includes: the service of the UE is required to run normally; the indication information is third indication information, and the third indication information is used for indicating that the second base station is a micro base station, and the macro base station where the second base station is located is the same as the macro base station where the first micro base station is located; the determining unit 13 is specifically configured to: determining whether the second base station meets the conditions required by normal operation of the service of the UE according to the indication information and the identifier of the UE; if the second base station is determined to meet the conditions required by normal operation of the service of the UE, determining that the second base station provides compensation service for the UE; and if the second base station is determined not to meet the conditions required by the normal operation of the service of the UE, determining that the macro base station where the second base station is located and the second base station provide compensation service for the UE based on the CoMP technology according to the fact that the user category of the UE is a double-micro base station user.
Specifically, the third indication information is used to indicate that the second base station is a micro base station, and the macro base station where the first micro base station is located is the same as the macro base station where the second base station is located, for example: the third indication information may be user indication information of a dual micro base station, then the determining unit 13 determines whether the second base station meets a condition required for normal operation of the service of the UE included in the association information of the UE according to the third indication information and the identifier of the second base station, if the determining unit 13 determines that the second base station meets the condition required for normal operation of the service of the UE, which indicates that the second base station alone provides service for the UE and can ensure that the service of the UE operates normally, then the determining unit 13 determines that the second base station provides compensation service for the UE, and then the second base station can provide compensation service for the UE according to the standard that the serving base station of the UE provides the micro base station for the UE; if the determining unit 13 determines that the second base station does not satisfy the condition required by the normal operation of the service of the UE, which indicates that the second base station alone provides the service for the UE and cannot ensure the normal operation of the service of the UE, the determining unit 13 determines the macro base station where the second base station is located (i.e., the macro base station where the first micro base station is located) and the second base station provide the compensation service for the UE.
In a fourth possible implementation manner, the association information of the UE received by the receiving unit 11 further includes: the service of the UE is required to run normally; the indication information is fourth indication information, and the fourth indication information is used for indicating that the second base station is a micro base station, and the macro base station where the second base station is located is different from the macro base station where the first micro base station is located; the determining unit 13 is specifically configured to: determining whether the second base station meets the conditions required by normal operation of the service of the UE according to the fourth indication information and the identifier of the second base station; if the second base station is determined to meet the conditions required by normal operation of the service of the UE, determining that the second base station provides compensation service for the UE; and if the second base station is determined not to meet the conditions required by the normal operation of the service of the UE, determining that the macro base station where the second base station is located and the second base station provide compensation service for the UE based on the CoMP technology.
Specifically, the fourth indication information is used to indicate that the second base station is a micro base station, and the macro base station where the first micro base station is located is different from the macro base station where the second base station is located, for example: the third indication information may be user indication information of an adjacent micro base station, then the determining unit 13 determines whether the second base station meets a condition required for normal operation of the service of the UE included in the association information of the UE according to the fourth indication information and the identifier of the second base station, if the determining unit 13 determines that the second base station meets the condition required for normal operation of the service of the UE, which indicates that the second base station alone provides service for the UE and can ensure that the service of the UE operates normally, then the determining unit 13 determines that the second base station provides compensation service for the UE, and then the second base station can provide compensation service for the UE according to the standard that the serving base station of the UE provides compensation service for the micro base station; if the determining unit 13 determines that the second base station does not satisfy the condition required by the normal operation of the service of the UE, which indicates that the second base station alone provides the service for the UE and cannot ensure the normal operation of the service of the UE, the determining unit 13 determines that the macro base station where the second base station is located and the second base station provide the compensation service for the UE.
Optionally, if the macro base station where the first micro base station is located is different from the second base station, the determining unit 13 is further configured to determine that the load of the macro base station where the second base station is located is less than or equal to a second threshold before determining that the macro base station where the second base station is located and the second base station provide the compensation service for the UE based on the CoMP technology. In this embodiment, the determining unit 13 determines, according to the fourth indication information, that the macro base station where the first micro base station is located is different from the macro base station where the second base station is located, so that before determining that the macro base station where the second base station is located and the second base station provide the compensation service for the UE based on the CoMP technology, the determining unit 13 needs to determine whether the load of the macro base station where the second base station is located is greater than a second threshold, and if the determining unit 13 determines that the load of the macro base station where the second base station is located is less than or equal to the second threshold (for example, 0.9), it is determined that the available network resources of the macro base station where the second base station is located are more, and the macro base station where the second base station is located may provide the compensation service for the UE based on the CoMP technology, thereby determining that the macro base station; if the determining unit 13 determines that the load of the macro base station where the second base station is located is greater than the second threshold, it indicates that the available network resources of the macro base station where the second base station is located are less, and the macro base station of the second base station cannot provide the compensation service for the UE, and then the procedure is ended.
