Description
Technical field
The present invention relates to the mobile communication technology field, more particularly, relate to the determination methods and the portable terminal of a kind of terminal area state.
Background technology
In order to adapt to the high-speed radio business demand, the 3GPP of International Standards Organization (3rdGeneration Partnership Project, third generation partner program) etc. formulate the tissue of wireless communication standard with OFDM (Orthogonal Frequency DivisionMultiplexing, abbreviating OFDM as) technology includes the next generation wireless communication system in, for example, Long Term Evolution (Long Term Evolution the abbreviates LTE as) system of studying at present.The employing orthogonal frequency division multiplexi can make the terminal service signal each other that belongs to same sub-district keep quadrature, thereby avoids the terminal room phase mutual interference of same sub-district.In order to improve frequency efficiency, generally adopting frequency duplex factor as one is 1 cellular layout, and still, this has inevitably brought presence of intercell interference (Inter-Cell Interference abbreviates ICI as).Therefore, how to reduce the major issue that presence of intercell interference becomes the next generation wireless communication system.
Inter-Cell Interference Coordination (Inter-Cell Interference Coordination abbreviates ICIC as) is called partial frequency multiplexing or soft-frequency reuse usually again, is at present by the technology that is used to reduce presence of intercell interference of extensive discussions.The core concept of ICIC is: judge that at first service terminal is sub-district inside terminals or cell edge terminal, by the diverse location type terminals is distributed different resources, make the used resource quadrature of edge termination between neighbor cell as far as possible, thereby reduce the interference of minizone.Because this technology is used flexibly, realizes simple, satisfactory for result, so become the mainstream technology of minimizing presence of intercell interference very soon.The problem that utilization ICIC technology at first will solve is how distinguishing cell inside terminals and cell edge terminal.
In the discussion of present 3GPP, determine that terminal location mainly is the mensuration by pilot signal strength, be specially reference symbol energy (Reference Symbol Received Power abbreviates RSRP as) and measure.The name of submitting to 3GPP in October, 2007 is called " band/not with the Inter-Cell Interference Coordination scheme of business load indication: On Inter-cell InterferenceCoordination Schemes without/with Traffic Load Indication " (motion number: point out in motion R1-074444) that RSRP measures can provide ICIC needed geographical location information.And, need know more customer position information simultaneously in order to make the bigger effect of ICICI performance.
The name of submitting to 3GPP in February, 2006 is called " performance of the descending semi-static frequency planning presence of intercell interference weakening technology of EUTRA: Performance of Inter-CellInterference Mitigation with Semi-Static Frequency Planning forEUTRA Downlink " (motion number: in motion R1-060368), just point out according to location information of terminals, it is good more to incorporate the systematic function that the many more ICIC of number of cell edge terminal bring in limited scope into, more RSRP report and can bring big signaling consumption and high amount of battery consumption simultaneously, how reducing this signaling consumption and amount of battery consumption is a problem, be called " the RSRP measurement triggering that ICIC is newly-increased: Additional RSRP reporting trigger for ICIC " (motion number: in motion R1-0801536), propose to report the signaling consumption that brings to be necessary to increase new triggering thresholding such as the name of submitting to 3GPP in March, 2008 in order to reduce RSRP.Simultaneously the name of submitting to 3GPP in March, 2008 is called " ICIC sub-district inside terminals and exterior terminal definition: Consideration onidentification of interior users/exterior users for ICIC " (motion number: in motion R1-081395), also proposed in order to reduce the signaling consumption that reporting of RSRP brought, triggered RSRP according to terminal suspending zone state and efficient signaling and report.
To report the signaling consumption that brings in order reducing to measure, suitable thresholding just need to be set to control cell edge and inside terminals.The name of submitting to 3GPP in October, 2007 is called " band/not with the Inter-Cell Interference Coordination scheme of business load indication: On Inter-cell InterferenceCoordination Schemes without/with Traffic Load Indication " (motion number: point out in motion R1-074444), can use handover measurement user position information is provided, know more customer position information for needs simultaneously, need to improve the triggering thresholding, but this method of using handover measurement, can make the periodic reporting measurement result of user, increase the expense of up signaling.The name of submitting to 3GPP in March, 2008 is called " the RSRP measurement triggering that ICIC is newly-increased: Additional RSRP reporting trigger for ICIC " (motion number: in motion R1-0801536), suggestion is 6dB with this threshold setting, allow more reporting of user measurement result, limit the signaling consumption that reports by increasing extra trigger mechanism simultaneously, but the quick variation of the terminal location metrical information that the quick variation of not considering the mobile channel environment causes, and " ping-pong " that cause.
In currently used appraisal procedure, the inventor finds to have following problem in the prior art at least: the process of judging Cell Edge User and internal user can produce " ping-pong ", increases overhead.
