Under the scene of the network design of traditional LTE, terminal needs the cell ID knowing Serving cell, to use when subsequent demodulation controls.Terminal can by detecting PSS (the Primary Synchronization Signal of cell broadcast service, master sync signal) and SSS (Secondary Synchronization Signal, auxiliary synchronous signals) obtain the cell ID of Serving cell.Same, terminal is detecting RSRP (the Reference Signal Receiving Power of adjacent area, Reference Signal Received Power) or RSRQ is (Reference Signal Receiving Quality, Reference Signal Received Quality) time, in the process reported, also need the result of RSRP or RSRQ and corresponding cell ID to report Serving cell together.
In addition, unauthorized frequency range needs fair remove shared resource, therefore before busy channel resource, the free time needing monitor channel resource whether, then just can go to take resource.After taking resource, terminal needs the RRM (Radio Resource Management, RRM) carrying out Serving cell and face community to measure.Because in unauthorized frequency range, the operating state of community is uncertain, therefore can consider that the DRS (Discovery Reference Signal finds reference signal) by introducing in the 3GPP Rel-12 stage measures.And the time-frequency location of the transmission of the DRS of adjacent area and Serving cell may be different.
When existing deployment of LTE network, different operators can take different mandate frequency ranges, certain is authorized frequency range to distribute to an operator and independently uses, and therefore operator can solve the problem of the cell ID conflict between neighbor cell by rational network design.And in unlicensed spectrum, because frequency range may be that use is shared by multiple operator, and may dispose by coordination network between multiple operator, therefore may occur that the cell ID between neighbor cell is the situation of conflicting, in this case, the problem obscured that terminal occurs when report measurement results may be caused.
Therefore, how in unlicensed spectrum, can accurately identify the community of different operators, avoiding terminal to give the correct time in measurement becomes technical problem urgently to be resolved hurrily because cell ID collision causes confusion.

Technical scheme of the present invention is described in detail below in conjunction with Fig. 3 A to Fig. 4.
The present invention mainly proposes a kind of method being applied to the terminal recognition operator identifier of unauthorized frequency range, can effectively avoid terminal when report measurement information because cell ID collides the confounding issues brought.For this problem, the present invention mainly proposes three kinds of methods and solves, and is described one by one below:
Method one:
Identified by the signaling of DRS, under this approach, different operators can be identified by the Signalling Designing of different DRS.Illustrate with the deployment scenario of Liang Ge operator below, concrete method can be:
The transformat of the signaling transmitted in the DRS of operator 1 and operator 2 is distinguished, and be the transformat of signaling in the DRS of operator 1 as shown in Figure 3A, Fig. 3 B is depicted as the transformat of signaling in the DRS of operator 2.Wherein, the position of PSS and the SSS transmission in DRS is different for operator 1 and operator 2, and therefore terminal can go in the position detecting PSS and SSS to distinguish.
But, terminal needs Serving cell to notify the sequence of the DRS that different operators uses, this can pass through RRC signaling, MAC (Medium Access Control, medium education) CE (Control Element, control unit) or physical layer signaling realizes.Those skilled in the art it should be noted that, shown in Fig. 3 A and Fig. 3 B is only the transformat of DRS under one embodiment of the present of invention, wherein distinguish by the transmission location of PSS with SSS is different, can also be distinguished by the transmission location of other signalings of DRS in concrete realization.
Method two:
Identified by the configuration about DRS, under this approach, the configuration of the DRS between different operators can be different.Illustrate as follows with the scene of Liang Ge operator:
As shown in Figure 4, the different DMTC of money can join in different operators, such as configures the deviant of different DMTC.In this case, assuming that be all carry out synchronously based on GPS between different operators, the instruction of different operators is known in the position that so terminal can be transmitted by blind check DRS, or the position that serving BS transmits to the DRS of other operators of terminal notification, so that terminal carries out the search of DRS on a corresponding position to know that the community whether having other operator exists.Serving BS needs to be searched on a corresponding position by RRC signaling, MAC CE or physical layer signaling notification terminal.
Method three:
Indicated by the transmission of initial signal (initial signal), before transfer of data at present in unauthorized frequency range, introducing initial signal may be needed to carry out the reserved of resource and other function, therefore can consider the instruction introducing operator in initial signal.
Specifically, the sequence of different initial signal can be used to realize by different operators.In this case the sequence pond coordinating to use may be needed between different operators, this coordination can be very static, such as can by pre-defined two sequence ponds, two different operators only take one of them sequence pond so that it is different for realizing the sequence that different operators uses, and such terminal can be known by the sequential value detecting initial signal and distinguishes different operators.
Terminal effectively can be realized when detecting by the technical scheme of the above embodiment of the present invention, correct identification can there be two or more communities of identical cell ID, thus give the correct time on measuring, base station can know that the community of measurement is the community under this operator on earth, so that follow-up operation.
More than be described with reference to the accompanying drawings technical scheme of the present invention, consider in unlicensed spectrum, because frequency range may be that use is shared by multiple operator, and may dispose by coordination network between multiple operator, therefore may occur that the cell ID between neighbor cell is the situation of conflicting, in this case, the problem obscured that terminal occurs when report measurement results may be caused.Therefore, the present invention proposes a kind of scheme identifying operator identifier in unauthorized frequency range newly, can guarantee that terminal accurately recognizes the community of different operators in unauthorized frequency range, avoid terminal when report measurement information because cell ID collides the problem caused confusion.
