Abstract
The invention provides a survey and dispatching method when a dual-mode terminal is operated under a mode of TD-SCDMA network. The method comprises: obtaining leisure time frame information in a TD-SCDMA subframe according to configuration information of a current terminal business channel, a service cell and an adjacent cell; judging whether a leisure time frame comprising TSO time slot is present and judging whether the length of the leisure time frame satisfies the time demand for measuring the adjacent cell of an unusual system; dispatching the measurement of a pilot adjacent cell and the adjacent cell of the unusual system according to the judged result. According to the invention, a reasonable dispatch for measuring the pilot adjacent cell and the adjacent cell of the unusual system is realized, thus ensuring that cell reselection or switching in the TD-SCDMA system and cell reselection or switching from the TD-SCDMA cell to cells (such as a GSM cell) of other systems can be well accomplished by a shared antenna automatic dual-mode terminal active in the TD-SCDMA network mode under various complicate configuration conditions.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to the measurement scheduling method of the automatic mode mobile terminal of shared antenna 3G when being operated in the TD-SCDMA network schemer.
Background technology
At present, 3-G (Generation Three mobile communication system) (The 3rd Generation Mobile CommunicationSystem abbreviates 3G as) is showed its powerful effect power just in the world, and many operators have set up the 3G system of self.At home, China Mobile has taken the lead in having set up the 3G examination commercial network based on the TD-SCDMA technology of one of 3G mainstream technology, and beginning provides colourful 3G business experience for the user.Meanwhile, be that the second generation mobile communication technology of representative is quite ripe with the GSM network, have huge and perfect infrastructure and a large number of users, and himself is also in evolution constantly.Can predict in quite a long time from now on, GSM network and TD-SCDMA network can exist simultaneously.Therefore as emerging TD-SCDMA 3G portable terminal, have both TD-SCDMA network work pattern and GSM network work pattern and can cover situation (or network control) transformation working pattern automatically according to network signal, being the automatic dual mode capability of TD-SCDMA/GSM, is one of its key function.
For the minimizing system realizes complexity and reduces cost, in the existing automatic mode mobile terminal of TD-SCDMA/GSM, general TD-SCDMA transceiver and the GSM transceiver of adopting is by the shared common antenna scheme of duplexer, because portable terminal can not be operated in TD-SCDMA network schemer and GSM network schemer simultaneously.But in order to make the automatic mode mobile terminal of TD-SCDMA/GSM cover situation (or network control) transformation working pattern automatically according to network signal, when this just needs dual-mode terminal to work in a kind of network schemer, can finish measurement, so that initiate intersystem cell reselection or handoff procedure near another kind of network schemer cell signal situation; If intersystem cell reselection or handoff procedure are successful, also promptly successfully finished the working mode change of dual-mode terminal.
In the 3G mobile communication system, the measurement type that is in the portable terminal execution of TD-SCDMA network work pattern comprises: common frequency measurement, different-frequency measure, different system measurements, data traffic measurement, channel quality measurement and terminal inner are measured.Because only to single sub-district (being Serving cell) and only execution when having business to carry out, it is fairly simple that it measures scheduling for data traffic measurement, channel quality measurement and terminal inner measurement.The present invention is in the measurement scheduling that the automatic mode mobile terminal of the shared antenna 3G of TD-SCDMA network work pattern is carried out the measurement type that relates to many sub-districts with concern.Many cell measurements comprise in the system to be measured and different system measurements, measures in the system to comprise that common frequency measurement and different-frequency measure, iso-frequency adjacent community measurement hereinafter are to measure in a kind of system.
The subframe structure of TD-SCDMA system as shown in Figure 1.(TS0～TS6) and 3 special time slots (DwPTS, GP, UpPTS) are formed, and the subframe duration is 5 milliseconds, and TS0～TS6 duration is 675 microseconds, and the DwPTS duration is 75 microseconds, and the GP duration is 75 microseconds, and the UpPTS duration is 125 microseconds by 7 normal time slots for it.The reference measure physical channel of measuring as cell signal strength, i.e. beacon channel P-CCPCH (Primary Common Control Physical Channel) is to be fixed on the code channel 0 and code channel 1 of time slot TS0 of main carrier frequency, and exists in each TD-SCDMA subframe.
Because in the TD-SCDMA system, the subframe of each sub-district keeps synchronous by GPS (global positioning system), and the TS0 of main carrier frequency goes up the Traffic Channel that general not configuration needs terminal to receive continuously, therefore portable terminal to the measurement that time slot TS0 goes up different districts P-CCPCH channel, just can obtain the adjacent cell signal strength of TD-SCDMA by rational management.
In gsm system, a tdma frame (duration is 4.615 milliseconds) is divided into 8 time slots.Each sub-district of GSM network has a BCCH carrier frequency that carries broadcast channel at least, and this carrier frequency omnidirectional, constant power ground is emission uninterruptedly on all time slots, so portable terminal can carry out at any time to the measurement of GSM cell signal strength.
Scheduling or to trigger various measurements are one of key functions of providing of physical layer control module.In the automatic mode mobile terminal of shared antenna, the physical layer control module need be taken all factors into consideration terminal current working state, traffic channel configuration situation, Serving cell and adjacent cell, and (adjacent cell comprises native system co-frequency neighbor cell, native system iso-frequency adjacent community and different system adjacent sub-district three classes, all can reach 32 adjacent sub-districts) configuration information, dispatch physical layer and measure.Therefore, how reasonably to dispatch physical layer and measure, avoid any possible Radio Resource conflict, especially will avoid TD-SCDMA transceiver and GSM transceiver contention, just become the technical problem that needs to be resolved hurrily common antenna.
Summary of the invention
