Description
Technical Field
The invention relates to the field of UE measurement configuration, in particular to an intelligent UE measurement configuration method and system of a shared base station.
Background
In a mobile communication system, the handover process is divided into 4 steps: measurement, reporting, judgment and execution. The received power, bit error rate and link distance can be used as measurement criteria to make theoretical estimation and corresponding processing. The measurement process therein is a very important loop.
The measuring process mainly comprises the following three steps:
measurement configuration: and the base station informs the UE of the measurement configuration message through the RRCConnectionReconfiguration message, namely, the measurement control is issued.
Measurement execution: the UE will measure the current serving cell and determine whether to perform measurement on the neighboring cell according to the rrcconnectionreconfiguration message.
And (3) measurement report: measurement report triggering modes are divided into periodic and event triggering. And when the measurement report condition is met, the UE fills the measurement result into a measurement report message and sends the measurement result to the base station.
The measurements performed by the UE include: common frequency measurement, pilot frequency measurement, measurement with UTRAN, and measurement with GERAN. According to different states of the UE, the UE measurement can be divided into measurement in an RRC _ IDLE state and measurement in an RRC _ CONNECTED state.
Measurement in RRC _ IDLE state: for cell reselection;
measurement in RRC _ CONNECTED state: for redirection.
According to different measurement types of UE, the method can be divided into common-frequency measurement, pilot-frequency measurement and Inter-RAT measurement:
and (3) measurement of same frequency: the measurement is carried out on the downlink carrier frequency of the service cell, and the measurement comprises the following steps: RSRP, RSRQ, Patholoss, etc.
And (3) pilot frequency measurement: and the measurement is carried out on a downlink carrier frequency different from the serving cell, and the measurement comprises RSRP, RSRQ, Pathloss and the like.
Inter-RAT measurements: PCCPCH RSCP, CPICH RSCP, CPICH Ec/No, GSM Carrier RSSI, BSIC Identification, BSIC reconfiguration, etc.
When the signal measured by the UE satisfies the measurement report condition, the signal is reported to the base station through an event. The report content comprises: measurement ID, measurement results of the serving cell (measurement values of RSRP and RSRQ), measurement results of the neighbor cells, so that the base station makes a decision on handover.
In a conventional base station, particularly a non-shared base station, the UE measurement technology does not distinguish information such as the attribute or type of a cell to be measured and the UE capability, and a uniform measurement configuration method and measurement configuration messages with the same configuration are adopted for all UE users. However, this method is not applicable to shared base stations. As there may be other shared base stations or non-shared base stations for the neighboring cell base station (assumed to be base station B) in the vicinity of the shared base station (assumed to be base station a). Base station a and base station B may be base stations with two different frequency bands (for example, shared base station a uses the frequency band of operator 1 to simultaneously serve operator 1 and operator 2, and base station B uses the frequency band of operator 2), and UE can support the frequency band of base station a, but cannot necessarily support the frequency band of base station B. If the UE capability does not support a certain frequency band, even if measurement configuration such as frequency points in the frequency band is sent to the UE, the measurement configuration is redundant or useless for the UE. And on the light side, the UE cannot perform measurement or prolongs the reporting time of the measurement report. In particular, the UE may affect the measurement of the useful frequency band, resulting in the UE underreporting the measurement report information of the useful frequency band. For the base station, besides that a certain extra waiting time needs to be consumed and the UE reports the measurement report underly, what is most important is that the handover decision and execution process of the base station are affected, and problems such as too late handover or call drop may be caused by handover to a cell that best meets the conditions.
