Description

A kind of cell selecting method and device
Technical field
The present invention relates to the communications field, particularly relate to a kind of cell selecting method and device.
Background technology
Carrier aggregation (English full name: CarrierAggregation, English abbreviation: CA) be long-term evolution upgrading version (English full name: LongTermEvolutionAdvanced, English abbreviation: LTE-A) in system for increasing the technology of transmission bandwidth, effectively can improve the capacity of single user peak rate and lte-a system.As shown in Figure 1, carrier aggregation network, comprise evolved base station (English full name: evolvedNodeB, English abbreviation: eNB) 1, evolved base station 2, evolved base station 3 and subscriber equipment (English full name: UserExperience, english abbreviation: UE), and in the coverage of evolved base station 1 micro-base station 1, micro-base station 2 in the coverage of evolved base station 2, micro-base station 3 in the coverage of evolved base station 3.Wherein, the coverage of evolved base station 1 is community (cell) 11, and the frequency of community 11 is f 1, the coverage of micro-base station 1 is community 12, and the frequency of community 12 is f 2, the coverage of community 12 in the coverage of community 11, community 11 and component carrier aggregation cell pair, community 12; The coverage of evolved base station 2 is community 21, and the frequency of community 21 is f 1, the coverage of micro-base station 2 is community 22, and the frequency of community 22 is f 2, the coverage of community 22 in the coverage of community 21, community 21 and component carrier aggregation cell pair, community 22; The coverage of evolved base station 3 is community 31, and the frequency of community 31 is f 1, the coverage of micro-base station 3 is community 32, and the frequency of community 32 is f 2, the coverage of community 32 in the coverage of community 31, community 31 and component carrier aggregation cell pair, community 32.Frequency f 1for main carrier, frequency is f 1community be main plot, frequency f 2be auxiliary carrier wave, frequency is f 2community be auxiliary community.Work as frequency f 1and frequency f 2when gap is less, frequency is f 1community and frequency be f 2the overlapped coverage of minizone larger; Work as frequency f 1and frequency f 2when gap is larger, frequency is f 1community and frequency be f 2the overlapped coverage of minizone less.And the overlapping region that the marginal existence of 6 communities is all overlapping each other.
In prior art, subscriber equipment carries out, with when frequently switching, only measuring the signal quality of subscriber equipment to main plot, do not measure the signal quality of subscriber equipment to auxiliary community by A3 event.Example, when subscriber equipment is attached to community 11, when moving from the overlay area of community 11 and community 12 to overlapping region, subscriber equipment is greater than A3 event thresholds value α to subscriber equipment to the signal quality of community 21 and subscriber equipment to the difference of the signal quality of community 11 by A3 affair 3meet A3 event, simultaneously, the signal quality of community 31 also meets A3 event, and be less than the signal quality of community 21, subscriber equipment sends A3 event measurement report to base station 1, and the wireless resource control connection reconfiguration message that subscriber equipment sends according to base station 1 (carry out from community 11 to community 21 with frequently switching by the instruction of (RadioResourceControlConnectionReconfiguration).After switching, subscriber equipment is measured to the signal quality of community 22, when subscriber equipment is greater than A2 event thresholds value to the signal quality of community 22, A2 event measurement report is sent to base station 1, then the instruction allocating cell 22 of wireless resource control connection reconfiguration message that sends according to base station 1 of subscriber equipment is as the auxiliary community of subscriber equipment, otherwise, allocating cell 22 is not as the auxiliary community of subscriber equipment, until the signal quality of community 22 meets A2 event, but, the signal quality of community 32 is better than the signal quality of community 22, thus community 31 is compared community 21 and community 22 and can be provided better signal quality for subscriber equipment with community 32.Therefore, subscriber equipment only carries out switching with frequency according to the signal quality of the subscriber equipment measured to main plot, cause the speed carrying out to be recovered in time by carrier aggregation after with switching frequently subscriber equipment at subscriber equipment, and improve the problem of single user peak rate and lte-a system capacity.

Base station judges that subscriber equipment is greater than A6 event thresholds value α to the signal quality of community 32 and subscriber equipment to the difference of the signal quality of community 12 6, then subscriber equipment meets A6 event thresholds value to the signal quality of community 32.
Base station judges that subscriber equipment is greater than A6 event thresholds value α to the signal quality of community 42 and subscriber equipment to the difference of the signal quality of community 12 6, then subscriber equipment meets A6 event thresholds value to the signal quality of community 42.
Base station can pre-set A6 event thresholds value.A6 event thresholds value can for setting in network optimization process, so that subscriber equipment obtains better performance of handoffs, concrete size is relevant with network environment.Third generation affiliate (English full name: 3rdGenerationPartnershipProject, English abbreviation: 3GPP) is defined between-15-15dB, and configuration A3 event thresholds value is greater than 0dB usually.
Step 308, base station compare any two and value, determine target main plot.
Described and value is for described subscriber equipment is to the signal quality of main plot and described subscriber equipment to the signal quality sum of auxiliary community.
Example, base station judges whether the signal quality of community 21 and the signal quality sum of community 22 are greater than the signal quality of community 31 and the signal quality sum of community 32, if the signal quality sum of the signal quality of community 21 and community 22 is greater than the signal quality of community 31 and the signal quality sum of community 32, judge whether the signal quality of community 21 and the signal quality sum of community 22 are greater than the signal quality of community 41 and the signal quality sum of community 42, if the signal quality sum of the signal quality of community 21 and community 22 is greater than the signal quality of community 41 and the signal quality sum of community 42, determine that community 21 is for target main plot.
It should be noted that, the concrete determination methods between two and value, can described in refer step 208 to step 2010.
Step 309, base station send the second wireless resource control connection reconfiguration message to subscriber equipment.
Described second wireless resource control connection reconfiguration message is used to indicate described subscriber equipment and is switched to described target main plot from described current main plot.
Step 3010, subscriber equipment are switched to described target main plot according to the second wireless resource control connection reconfiguration message from described current main plot.
It should be noted that, coverage Nei Fu community, target main plot needs identical with the frequency of described current auxiliary community and number is identical.
