Description
Technical field
The present invention relates to the communications fields, in particular to a kind of cell measurement processing method, device, terminal and base station.
Background technique
In cell mobile communication systems, cell reselection and switching are its important functions.In order to smoothly realize cell weight
Choosing, UE needs to measure the signal quality of different community, to select suitable cell to be resident.When UE is small at some
Area and network are established after connection, and UE is there is still a need for the signal quality of its neighboring community is measured, to select suitably
Cell switches over, and meets mobility requirement.
Under connected state, the detailed process of measurement is terminal: network side is sent to UE for control message is measured, wherein should
Measuring in control message includes measurement mark (Measurement Identity, referred to as MID), measurement object
(Measurement Object, referred to as MO), report configuration (Report Configuration, referred to as RC) and measurement
Other association attributes.UE goes to execute measurement according to measurement object, the report configuration in measurement control message, and is tied according to measurement
Fruit generates measurement report and is reported to network side.Each measurement task includes measurement mark, (such as carrier frequency (carries measurement object attribute
The center frequency point of wave, i.e. ARFCN), neighboring cell list etc.) and report configuration attribute (such as event triggering reports or periodic report, triggering
Event is defined (A1, A2 ...) by trigger condition, the relevant thresholding of trigger condition, offset etc., TTT (Time To Trigger)).
It is different according to the carrier frequency where measurement object, it is divided into common frequency measurement and different-frequency measure, the i.e. carrier frequency and serving cell of measurement object
The identical carrier frequency at place is then common frequency measurement, and the carrier frequency of measurement object and the carrier frequency difference where serving cell are then that alien frequencies is surveyed
Amount.According to the wireless access technology of measurement object, there are also isosystem measurement, isosystem measurement refers to that measurement object is not E-
The measurement task of UTRAN includes UMTS, GERAN and CDMA2000.Carrier frequency where serving cell refers to that UE and the service are small
The center frequency point that area is communicated.Measurement for common frequency measurement task, UE can directly execute measurement, not need measurement interval
(measurement gap).Due to the limitation of terminal capability, survey of some terminals for the measurement task of alien frequencies and different system
Amount needs network side configuration measurement interval, i.e. specified a period of time, during this period of time, UE is temporarily interrupted and serving cell
Communication go execute alien frequencies and different system measurement.If necessary to configure measurement interval, base station passes through wireless heterogeneous networks
Measurement interval is allocated to UE by (Radio Resource Control, referred to as RRC) reallocation message.The ginseng at configuration measurement interval
Number includes offset and period, and terminal measures the time that interval starts according to calculations of offset, and terminal periodic parameter determines measurement interval
Period and duration, there are two types of the current periods, and 40ms and 80ms, duration are all 6ms.Terminal calculates opening for measurement interval in this way
Begin the time: frame number determines: SFN mod T=FLOOR (offset/10 of configuration), subframe numbers determine: subframe=is configured inclined
Move mod10；Wherein T=MGRP/10；MGRP (Measurement Gap Repetition Period) is period assignment
40ms or 80ms.
In LTE, UE can only be communicated by a cell with base station under connected state, when UE executes alien frequencies and different system
When the measurement of measurement task, base station determines to configure measurement interval to UE, the information at this measurement interval, the understanding of base station and terminal
It is consistent, UE executes alien frequencies isosystem measurement, base station can not dispatch UE within the specified time of this measurement interval.
Due to the surge of the big flow business of the scarcity and mobile subscriber of frequency spectrum resource, using high frequency points such as 3.5GHz
The demand for carrying out hot spot covering is increasingly apparent, becomes new application scenarios using the node of low-power, gulps down in order that increasing user
The amount of spitting and enhancing travelling performance.But since the decaying of the signal of high frequency points is more severe, the coverage area of cell is smaller, and
Co-sited point, current many companies and operator do not tend to seek a kind of new enhanced scheme, dual link with existing cell
(Dual Connectivity) is exactly one of them.Terminal can be kept with more than two network nodes simultaneously under dual link
Connection, but control plane connection only has connection with one of cell such as macrocell.Multiple service nodes of terminal are multiple
Base station, the time delay between base station be can not ignore.For example, a network node is that macro base station is known as MeNB, another network section
Point is that small-cell base station is known as SeNB.When using a measurement interval, terminal needs are counted respectively on MeNB and SeNB
It at the beginning of calculating measurement interval, for example calculates all in accordance with the temporal information of MeNB, in this way, measurement interval is with existing on MeNB
Technology is the same, and the measurement interval on SeNB needs to calculate according to the temporal information of MeNB, if MeNB and SeNB sub-frame boundary
Alignment, then the interval time of measurement on SeNB is exactly to measure interval time i.e. two time on MeNB to be overlapped, as SeNB and
When the sub-frame boundary of MeNB is misaligned, at the beginning of how terminal calculates the measurement interval on SeNB, there has been no open
Technology.If base station is dispatched eventually for having different understanding at the beginning of measurement interval on SeNB in terminal and base station
End has a huge impact, and it is exactly waste of resource that resource is distributed when cannot dispatching for terminal, and terminal can be dispatched
When do not have distribute resource be exactly to reduce the handling capacity of terminal.
Therefore, in the related art, exist due to UE double-strand connect down can not determine measurement interval at the beginning of, cause to provide
