Description
Technical field
The present invention relates to a kind of method of testing of testing effects of interference between mobile communication systems, and be particularly related to the method for testing of a kind of test TD SDMA (Time Division-Synchronous Code DivisionMultiple Access) (hereinafter to be referred as TD-SCDMA) inter-system interference influence.
Background technology
The interference that causes owing to reasons such as unwanted radiation, obstructions between wireless communication system inside and the system is studied, the degree of assessment interference effect, thereby seek the measure of effectively evading interference, utilize valuable frequency resource with high efficient and reliable ground, radio communication service is provided, and is an important content in Research of wireless communication systems and the application always.
Third generation cell mobile communication systems (the 3rd Generation) (hereinafter to be referred as 3G) proposes from standard, because many kinds of standards of 3G (comprise TD-SCDMA, Wideband Code Division Multiple Access (WCDMA) (WidebandCode Division Multiple Access, abbreviation WCDMA), CDMA 2000 (CodeDivision Multiple Access 2000, be called for short CDMA2000)) need to coexist each other, and the 3G system needs also to realize coexistence with other wireless communication system such as existing second generation cell mobile communication systems that therefore relevant with 3G system interference is just complicated unusually.(the InternationalTelecommunication Union of International Telecommunications Union, abbreviation ITU), third generation partner program (the 3rdGeneration Partnership Project, be called for short 3GPP) and (the ChinaCommunications Standards Association of CCSA, be called for short CCSA) wait world, domestic standardization to be organized in the formulation 3G relevant criterion process, the interference problem that 3G is correlated with has been carried out deep research.Yet the main method that adopts qualitative analysis calculating or Monte-Carlo Simulation of this class research.The reliability of qualitative analysis result of calculation depends critically upon fixed such as getting of technical indicator such as equipment performance, wireless environment parameter or model, generally only be applicable to the interference between base station and base station is analyzed, and in most of the cases the result is tending towards pessimistic.Monte-Carlo Simulation is a kind of statistical simulation method, adopt this method assessment interference effect to be equivalent under given network design model and equipment performance condition, obtain a kind of statistical data about interference effect, therefore exist and " cover " very serious disturbance under some special scenes and be not the possibility that the researcher discovered to reflect various interference cases and influence degree thereof comprehensively, truly.
With respect to qualitative analysis calculating or Monte-Carlo Simulation, make up actual wireless communication system and interference is tested, also be a kind of important method of assessment interference effect.Owing to the complicated operation reason, generally for the test of disturbing many with relative system capacity user very in a small amount as system load, so can not reaction system at full capacity or under near full load to interference that other system produced or the interference of being born.
General disturbed test method, mainly the signal strength signal intensity of useful signal, the measurement of interference signal intensity are reacted with instrumentations such as spectrum analyzer, signal analyzers, after obtaining these measured values again in conjunction with concrete wireless communication devices index and network index, further analyze the influence degree of disturbing, so the result is directly perceived inadequately.
Summary of the invention
In view of above-mentioned, the purpose of this invention is to provide a kind of method of testing of the TD-SCDMA of test inter-system interference influence.
The peculiar problem of TD-SCDMA inter-system interference influence test is that TD-SCDMA is a kind of time division duplex (Time Division Duplex, be called for short TDD) system, and the transfer point between the uplink service time slot in the TD-SCDMA system (Time Slot is called for short TS), downlink business time slot can flexible configuration.When the uplink service time slot of two TD-SCDMA systems, transfer point between the downlink business time slot dispose when identical, the interference between system mainly is the interference between terminal equipment and base station equipment.And dispose when inequality when the uplink service time slot of two TD-SCDMA systems, transfer point between the downlink business time slot, such as the configuration (promptly up, downlink business time slot configuration ratio is 3: 3) of a TD-SCDMA system in these six business time-slots of TS1-TS6 be:
TS1, TS2, TS3: the uplink service time slot,
TS4, TS5, TS6: the downlink business time slot,
And another business time-slot configuration (promptly up, downlink business time slot configuration ratio is 2: 4) that covers the TD-SCDMA system of same area is:
TS1, TS2: the uplink service time slot,
TS3, TS4, TS5, TS6: downlink business time slot.
