Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Inventor notices in invention process:
Current mobile communications network is the mobile communications network of a multi-modulation scheme, such as, in mobile communications network, both supported GSM (Global System for Mobile communication, global system for mobile communications) 2G standard, also support WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA) access), TD-SCDMA (Time Division Synchronized Code DivisionMultiple Access, TD SDMA access), CDMA2000 (Code Division MultipleAccess2000, code division multiple access access 2000), WiMAX (World Interoperability for MicrowaveAccess, global microwave access intercommunication technology) etc. 3G standard, in existing mobile network, also may there is LTE (Long Term Evolution in the future, Long Term Evolution) and upgrade standard.The network of this multi-modulation scheme has many good qualities: first can support terminal and operator's smooth upgrade evolution; Second can make full use of existing resource, extends the useful life of original system; The 3rd can meet dissimilar business demand, such as telephone service, business of networking etc.; The 4th can have good compatibility, and the terminal of other multiple types can be operated in a large mobile network, and can well interconnect.
Under the network of this multi-modulation scheme, also will inevitably there is the terminal of multi-modulation scheme, so that seamless switching and meet the demand that different business is experienced between can support area, such as support the dual-mode terminal of GSM and WCDMA standard simultaneously, support the dual-mode terminal of GSM and TD-SCDMA standard simultaneously, support the dual-mode terminal of GSM and CDMA2000 standard simultaneously, and support three mould terminals of GSM, TD-SCDMA and LTE standard simultaneously, etc.Can predict, in the future, due to the more common existence of the mobile communication standard of multimode, the standard that terminal is supported simultaneously will get more and more.Along with the existence of multi-modulation scheme and multimode terminal, owing to requiring can to take over seamlessly between multimode, therefore, require multimode terminal to there is the ability of isosystem measurement, terminal not only needs to know the signal quality of current system of living in, meanwhile, it need to know neighbor cell and with the signal quality of different system covering, to facilitate terminal to be switched at any time goal systems or Target cell when the deterioration of this cell signal of native system.
At present, after different system mixed networking, described two different systems may be synchronous may be also nonsynchronous, with TD-LTE (Time Division-LTE, time division duplex-LTE) with TD-SCDMA system mixed networking be example, TD-LTE and TD-SCDMA system may be that what to synchronize may be also nonsynchronous, in order to allow terminal measure, network side can be that one of terminal configuration is measured interval, in this interlude, terminal can be carried out measurement, and network side can dispatch terminal in interval.Described interval is for measuring LTE system, analysis needs the 6ms time, reason is as follows: in nonsynchronous situation, when local area terminal is measured adjacent area, first to do synchronous search, the primary synchronization channel that synchronous search is required and auxiliary synchronization channel are positioned at subframe 0 and the subframe 1 of the front field of radio frames, and subframe 5 and the subframe 6 of rear field, therefore, in order to ensure that once receiving data must comprise primary synchronization channel and auxiliary synchronization channel, at least to receive the data of a field 5ms, consider nonsynchronous protection and and frequency switching time, need altogether under normal circumstances 6ms.
Described hypothesis is different in the situation that above, if but system is synchronous or has fixing timing offset or only have less synchronous error, consider that terminal is not too large apart from the distance of base station, time difference when so each base station down signal incoming terminal is not too large, in addition some measures that system self possesses anti-multipath are (such as (the Cyclic Prefix of the CP in LTE system, Cyclic Prefix)), some little synchronous errors are just negligible, terminal just can intercept 6ms data again and go to measure, measure but can intercept shorter data, base station needn't be also the long time of terminal configuration again, but can distribute the shorter time, such as, several time slots of a subframe are for measuring, the all right normal consistency of other time slots, can reduce the impact on native system scheduling.In current standard, terminal to be on the safe side, each measurement all will be done synchronous search, with the subframe original position of the different system of Obtaining Accurate, ensure synchronous, on synchronous basis, just can start different system to measure, if but to consider from reality, it is synchronous that same operator generally can be made system, to reduce inter-system interference.As can be seen here, if system is synchronous, for the different system adjacent area close to from the current subdistrict position of living in of terminal, terminal is in the time switching band, substantially be to think similar with the distance of distance base station, different system cell apart from this cell base station of native system, synchronous when if two systems itself are descending, reach so the timing offset of signal of end side also in its sustainable scope, therefore, in the case, terminal there is no need to do the synchronous search of different system again in fact, directly data intercept is measured, the synchronous protection of system self and multipath are eliminated mechanism can eliminate these small synchronous difference, for the different system adjacent area away from from the current subdistrict position of living in of terminal, the synchronous error of system self is eliminated mechanism and cannot have been worked, terminal just need to be done synchronous search, determine the original position of frame.Like this, whether network side can differ greatly by the mode notification terminal different system adjacent area of explicit or implicit expression and the synchronization discrepancy of terminal community of living in fact.Terminal just can be saved the amount of calculation of measurement according to this instruction.Base station scheduling is owing to need not being the too much resource of terminal distribution, to also increasing in the resource utilization of scheduling simultaneously.
In addition, current isosystem measurement only limits to some limited informations of notification terminal, such as frequency information, community ID (mark), scrambler etc., these information are general only for FDD (Frequency DivisionDuplex, Frequency Division Duplexing (FDD)) system of standard is enough, and for the system of TDD standard, because existing up channel on a carrier wave also has down channel, for TDM (Time DivisionMultiplexing, time division multiplexing) mode, if so measure the different system adjacent cell that these duplex modes are TDD, terminal need to be known its up-downgoing transfer point (such as TD-TTE uplink and downlink timeslot configuration form) accurately, can avoid like this measuring ascending time slot or measuring unwanted time slot, also can the different system cell of more effective strategy, taking TD-SCDMA systematic survey TD-LTE system as example, if TD-SCDMA system is not known the time slot allocation mode of TD-LTE system, the user of TD-SCDMA system can only get all time slot intersection of sets collection so, it is subframe 0, subframe 1 and subframe 5, (as shown in the table), the data message at every turn measuring is also fewer, and uplink-downlink configuration ratio is a semi-static parameter, in a period of time, a region is identical and constant, therefore, can pass through high-level signaling notification terminal, in uplink-downlink configuration mode 2 in following table, if know the up-downgoing transfer point of configuration, can measure so subframe 0, subframe 3, subframe 4, subframe 5, subframe 8, subframe 9, a TTI (TransmissionTime Interval, Transmission Time Interval) in the time measurable number of time slot than many 2 times originally, can promote undoubtedly the quality of measurement, improve accuracy of measurement, also can shorten Measuring Time.But current agreement not network enabled side configures the up-downgoing transformational relation of adjacent area around different system to terminal, the embodiment of the present invention puts the scheme that has proposed to improve isosystem measurement just before this: by the up-downgoing transitional information of the different system of network side notification terminal, terminal is carried out isosystem measurement accordingly.
The configuration of table 1:TD-LTE uplink and downlink timeslot
In table: DL (Down Link) is down link, UL (Up Link) is up link, and D represents that descending sub frame, S represent that pilot tone subframe, U represent sub-frame of uplink.
In sum, in current different system group network, the problem existing is that terminal cannot know between own and different system whether synchronize, thereby make terminal need the extra simultaneous operation of doing, increased the workload of terminal, in addition, current isosystem measurement does not have the up-downgoing transitional information of the different system of notification terminal, when being measured, terminal wastes Measuring Time, the meeting of waste measuring machine, and behavior is very blindly.Based on this, the embodiment of the present invention provides the scheme that different system is measured.

Step 102, terminal are determined when synchronous according to described instruction, and second communication system is measured, and terminal is determined when asynchronous according to described instruction, after second communication system is synchronously searched for, second communication system measured.
In enforcement, instruction is that the first communication system is by sending to message or the special measuring controlling message of terminal broadcast;
Or instruction is that the first communication system sends by the dedicated signaling sending to terminal;
Or instruction is that the first communication system is indicated by the configuration relation between the signaling sending to terminal.
In concrete enforcement, network side can by explicit signaling or implicit expression indicating terminal, whether it around synchronizes with native system different system adjacent area, to simplify terminal execution Cell searching to reach synchronous process.When signaling can be broadcast, carry, also can use dedicated signaling notification terminal, go back or can represent by the corresponding relation of several signalings synchronous.Terminal pins determines whether to carry out different system synchronization search procedure to the notice of network side.
