Detailed Description
Research shows that when the operator base station Enb sets the maximum power P-max that the configurable HPUE can reach to 26dbm, the System Information Block (System Information Block) SIB1/SIB3/SIB5 sets the maximum output power of the HPUE specified by power class 2 to operate in the B41 frequency band (HPUE PC 2). When selecting a Cell that provides HPUE services for HPUE, an important indicator is the minimum reference signal received power Qrxlevmin, also known as the minimum receive level value required by the Cell, which is indicated in q-RxLevMin (dBm) of SIB 1. The Qrxlevmin is a value of Reference signal Received Power (RSRP/epre) reported by a Cell supporting HPUE for all system information blocks SIB1/SIB3/SIB 5. For the same coverage, it is possible that more than two cells support serving the same HPUE, in which case the HPUE selects which Cell it resides in for research.

Fig. 1 is a block diagram of a base station 10 provided in the present disclosure. The base station 10 in the present disclosure may be a server, a processing device, a radio transceiver station, or the like having a communication function. As shown in fig. 1, the base station 10 includes: memory 11, processor 12, network module 13 and base station cell selection device 20.
The memory 11, the processor 12 and the network module 13 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The memory 11 stores a base station cell selection device 20, the base station cell selection device 20 includes at least one software function module which can be stored in the memory 11 in a form of software or firmware (firmware), and the processor 12 executes various function applications and data processing by running a software program and a module stored in the memory 11, such as the base station cell selection device 20 in the present disclosure, so as to implement the base station cell selection method in the present disclosure.
The Memory 11 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.

The various methods, steps and logic blocks disclosed in this disclosure may be implemented or performed.

The network module 13 is used for establishing a communication connection between the base station 10 and an external communication terminal through a network, and implementing transceiving operation of network signals and data. The network signal may include a wireless signal or a wired signal.
It will be appreciated that the configuration shown in fig. 1 is merely illustrative and that the base station 10 may include more or fewer components than shown in fig. 1 or may have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The present disclosure also provides a computer-readable storage medium comprising a computer program. The computer program is operative to control the base station 10 on which the computer readable storage medium is located to perform the following base station cell selection method.
Referring to fig. 2, the base station 10 performs cell selection by the following steps. The base station is covered with a plurality of base station cells, and the cells interact with pilot frequency reselection information (namely, LTE network signaling messages) transmitted by a Physical Broadcast Channel (PBCH) through the HPUE supporting high-performance user equipment (HPUE) at the PC2 level. The pilot frequency reselection information comprises a system information block SIB3 message or a SIB5 message.
The Cell may provide an operator white list and a system information block to enable the HPUE to stay in a Cell coverage area, and the HPUE may be configured to transmit power at a high power PC2 level, assist the base station to reduce the coverage area, and reduce the total network signaling overhead. The Cell and the base station side are configured with the same operator white list, and for example, the base station of which operator provides HPUE service for HPUE, the white list codes of different operators are different.
The method comprises the following steps.
Step S11, for any Cell covered by the base station, obtaining the minimum base station side signal reception strength reported by the HPUE in the coverage area of the Cell.
Step S12, calculating a first signal received strength according to the minimum base station side signal received strength and the power of the HPUE operating at the maximum output power PC2 specified by the power class 2.
Wherein, assuming that the Tdd subframe configuration of HPUE is not changed, the neighboring Cell is configured to 00, 01 or 10 under SIB5, and the maximum output power PC2 specified by power class 2 is 26 dbm. When the P-max is increased to 26dBm, it is only necessary to adjust the Minimum required Rx level in the cell (dBm) under the SIB3/SIB5 message at the base station side to specify under which cell the HPUE resides.
For example, if the minimum base station side signal reception strength of Cell1 reported by the HPUE is-85 dbm/epre, the first signal reception strength is equal to a difference Δ dB between the maximum output power 26dbm specified by the power level 2 and the minimum base station side signal reception strength-85 dbm/epre reported by the HPUE, and Δ dB =26dbm- (-85 dbm/epre) =111 dB. Δ dB may be defined as a Cell selection Rx level value (dB), Srxlev, received strength value selected by the base station Cell.
Step S13, calculating a second signal reception strength according to the reception strength set for the Cell and the power of the HPUE when operating with the PC 2.
The reception intensity for the Cell may be set by: and adjusting the signal receiving strength of each Cell covered by the base station in the pilot frequency reselection information of the base station, so as to obtain the receiving strength set for each Cell. For example, the SIB3/SIB5 message may include the parameter value of the field q-QualMin-r10, and the reception strength set for the Cell may be obtained by adjusting the parameter value.
For example, assuming that the reception intensity set for the Cell1 is-80 dbm, the second signal reception intensity is equal to a difference Δ dB between the maximum output power 26dbm specified at the power level 2 and the reception intensity-80 dbm set for the Cell1, Δ dB =26dbm- (-80 dbm/epre) =106 dB.
Step S14, determining whether the first rssi is greater than the second rssi, and if the first rssi is greater than the second rssi, performing step S15. If the first rssi is less than or equal to the second rssi, step S16 is executed.
Step S15, rejecting the HPUE to reside under the Cell.
Step S16, allowing the HPUE to reside under the Cell.
For example, for Cell1, the first signal reception strength 111 is greater than the second signal reception strength 106, and thus, the HPUE is rejected to reside under Cell1, and Cell1 is not adopted to provide HPUE services for the HPUE.
For example, assuming that Cell1 and Cell2 are adjacent cells to each other, the maximum output power PC2 specified by power class 2 is 26 dbm. The receiving strength set for the Cell2 is-100 dbm/epre, and the minimum base station side signal receiving strength of the Cell2 reported by the HPUE is-85 dbm/epre, then, the first signal receiving strength is equal to a difference Δ dB between the maximum output power 26dbm specified by the power level 2 and the minimum base station side signal receiving strength-85 dbm/epre reported by the HPUE, and Δ dB =26dbm- (-85 bm/epre) =111 dB. The second signal reception intensity is equal to a difference Δ dB between a maximum output power 26dbm specified at a power level 2 and a reception intensity-100 dbm set for the Cell1, Δ dB =26dbm- (-100 dbm/epre) =126 dB. In contrast, for Cell2, the first rssi 111 is smaller than the second rssi 126, so that HPUE is allowed to reside under Cell2, and Cell2 is adopted to provide HPUE services for HPUE.
Referring to fig. 3, if two neighboring cells exist, if the HPUE reports minimum base station side signal reception strength for more than two cells covered by the base station, respectively, and the HPUE can reside in more than two cells according to a result obtained by analyzing the two minimum base station side signal reception strengths reported by the HPUE, the following steps may be performed.
Step S21, adjusting the reception strength of two or more cells capable of providing HPUE services for the HPUE in the pilot frequency reselection information of the base station.
Step S22, determining the Cell in which the HPUE finally resides, based on the adjusted reception intensity set for each Cell.
For example, the Receiving strength of the two or more cells capable of providing the HPUE service for the HPUE is adjusted according to Reference Signal Receiving Power (RSRP) of the two or more cells capable of providing the HPUE service for the HPUE. For example, according to Reference Signal Receiving Power (RSRP) reported by the HPUE to two or more cells, the minimum base station side Signal Receiving strength Qrxlevmin of one Cell is cooperatively determined, so that the HPUE selectively resides in the Cell.
Due to the fact that the RSRP values reported by the HPUE to the adjacent cells are different, the HPUE can be selectively made to reside under the corresponding Cell to provide HPUE service by adjusting the Qrxlevmin under the Cell. According to actual requirements, cells with better RSRP can be selected to provide services, and correspondingly, cells with worse RSRP can also be selected to provide services.
In order to more clearly illustrate the implementation principle of the present disclosure, the following scenario is taken as an example to illustrate the implementation flow of the present disclosure.
The base station side and the HPUE are configured with a consistent white list, the SIB3 and the SIB5 detect that the user terminal supports the HPUE, the maximum output power PC2 specified by the power level 2 is 26dbm, and the SIB3 message edge cell config =10 configured in the neighboring cell.
Suppose that the reference signal received power reported by the HPUE in the current cell of the base station is-89 dbm, and at this time, the HPUE resides in the cell, and the received power of the reference signal reported by the base station in the neighboring cell is-105 dbm. If the field q-QualMin-r10 under the SIB3 message of the current base station cell is-85 dbm, the field q-QualMin-r10 of the corresponding neighbor cell is-100 dbm, and the Srxlev1 of the current cell is calculated by the following formula:
Srxlev1=Δ dB=26-(-85)=111dbm。
srxlev2= Δ dB =26- (-100) =126dbm for neighbor cells, and the HPUE only resides in the current base station cell and does not follow the network handover to the neighbor cells, i.e. resides in a cell with strong signal. If the HPUE terminal needs to be switched to the adjacent cell, namely the cell with weak signals, the value > -85dbm of the q-QualMin-r10 field of the current cell needs to be increased or the q-QualMin-r10< -100dbm of the adjacent cell needs to be reduced, and then the HPUE terminal can stay in the adjacent cell with weak signals. And vice versa if it is intended to camp in a cell with strong signal.
On the basis of the above, as shown in fig. 4, the present disclosure provides a base station Cell selection apparatus 20, which is applied to a base station, where the base station is covered with a plurality of base station cells Cell, and the Cell interacts with pilot frequency reselection information transmitted by a high performance user terminal HPUE through a physical broadcast channel PBCH.

Since the information calculating module 22 is similar to the implementation principle of step S12 and step S13 in fig. 2, it will not be further described here.
The Cell selection module 23 is configured to determine whether the first signal reception strength is greater than the second signal reception strength, and if the first signal reception strength is greater than the second signal reception strength, reject the HPUE to reside under the Cell; if the first RSSI is less than or equal to the second RSSI, allowing the HPUE to reside in the Cell.
Since the cell selection module 23 is similar to the implementation principle of steps S14 to S16 in fig. 2, it will not be further described here.
