Embodiment

Basic thought of the present invention is according to the relation that compares Serving cell pilot channel RSCP and adjacent area carrier power, weak signal frequency that rejecting need not to measure or the cell power under this frequency are measured, to reach the purpose that the potential target sub-district is measured as much as possible in the finite time.Technology of the present invention is mainly used in multimode terminal and resides in the sub-district of CDMA type and carry out nearby region measurement, the adjacent area here can comprise adjacent sub-district of CDMA type and the adjacent sub-district of non-CDMA type, and CDMA type sub-district wherein comprises the sub-district of types such as TD-SCDMA, TD-CDMA, WCDMA, IS-95 CDMA, CDMA2000, CDMA2000EVDO, the sub-district that non-CDMA type sub-district comprises types such as GSM, PHS.

For this reason, the invention provides a kind of nearby region measurement method of multimode terminal, as shown in Figure 1, this method comprises:

Step 101: adjacent area carrier power rssi measurement is carried out in each frequency adjacent area, simultaneously Serving cell pilot channel received signal code power RSCP is measured;

Step 102: relatively Serving cell pilot channel RSCP and adjacent area RSSI, during less than Serving cell pilot channel RSCP, do not carry out pilot channel RSCP measurement to the adjacent area under this frequency after the RSSI under certain frequency adds Upper threshold; Otherwise the adjacent area pilot channel RSCP that carries out under this frequency measures.

In order to make those skilled in the art better understand the present invention, method of the present invention is elaborated below in conjunction with the drawings and specific embodiments.

Embodiment 1, is example with CDMA and gsm system, the two different each other system; CDMA is example with TD-SCDMA in the present embodiment: in the TD-SCDMA system, usually with the P-CCPCH channel as pilot channel, this moment, cell signal strength was generally used P-CCPCH channel received signal code power (RSCP, Received Signal Code Power) expression, rather than carrier power (RSSI); For example, portable terminal need be by measuring CPICH (Common Pilot Channel) RSCP and P-CCPCH (Primary Common Control Physical Channel) RSCP to obtain cell signal strength, under holding state, terminal is by comparing the signal strength signal intensity of Serving cell and adjacent area, the Autonomous Control cell re-selection procedure, under connection status, terminal need be reported to network side with the nearby region measurement result, by the cell signal strength that the network side analysing terminal reports, switch to determine whether indicating terminal carries out business;

And in gsm system, can be with the BCCH channel as pilot channel, this moment, cell signal strength was by BCCH (Broadcast Control Channel, Broadcast Control Channel) carrier power (RSSI) expression, and the bcch carrier transmitted power is constant generally speaking, so the TD-SCDMA terminal can all can measure the GSM carrier power in any free time window; Whether and in addition, network is surveyed and generally can be required terminal that BSIC (Base Station Identification Code Base transceiver Station Identity Code) identification is carried out in the stronger several sub-districts of power, be effective GSM sub-district to confirm;

Under connection mode, terminal can be attempted the detection of BSIC continuously by idle window, but for two different systems, because of the frame structure difference, terminal is generally very long in the time of specific idle window IT GSM sub-district BSIC, under the TD-SCDMA standard, the maximum duration of a GSM sub-district of capture terminal BSIC is about 660ms under the business model, during this period of time, SCH (Synchronization Channel synchronizing channel) time slot only can occur once in this free time window, but consider the complexity of wireless environment, if deep fade appears in this moment, then capture time will be a plurality of 660ms cycles; Therefore, in the TD-SCDMA system, with TS0, DwPTS time slot adjacent area P-CCPCH RSCP in the system is measured usually; And under the low speed business model, terminal can be carried out GSM adjacent area BSIC by the idle window of business time-slot and confirmed, and under the high speed business situation, does not generally have effective free time window, this kind situation confirms for carrying out GSM adjacent area BSIC, must utilize special time slot such as TS0 to advance to measure;

And in embodiments of the present invention, with most important different being of prior art: according to the relation between the measured value of relatively Serving cell P-CCPCH RSCP, TDD adjacent area P-CCPCH RSCP and GSM adjacent area RSSI, determine which adjacent area is better than present Serving cell, which cell signal is more weak and need not to carry out P-CCPCH RSCP and measure; Concrete, as shown in Figure 2

S201: carry out the adjacent area rssi measurement, simultaneously Serving cell is carried out P-CCPCH RSCP and measure;

Concrete, in some cycles, evenly carrier power (RSSI) is carried out in all adjacent areas and measure, also Serving cell is carried out P-CCPCH RSCP simultaneously and measure; Wherein, all adjacent areas comprise homologous ray (Intra-RAT) sub-district, adjacent area and different system (Inter-RAT) sub-district, adjacent area, and wherein also know the P-CCPCH RSCP of all adjacent areas of homologous ray, can know by prior art herein, do not repeat them here;

S202: compare Serving cell P-CCPCH RSCP and adjacent area RSSI;

Concrete, described adjacent area RSSI is divided into homologous ray adjacent area RSSI and the adjacent area RSSI of different system; Simultaneously, relatively carry out under certain each frequency, different frequencies causes the possibility of result difference of comparison herein;

S203: greater than Serving cell P-CCPCH RSCP, the adjacent area RSCP that then carries out this frequency measures after homologous ray adjacent area RSSI adds Upper threshold; Otherwise, finish;

S204: greater than Serving cell P-CCPCH RSCP, the adjacent area RSCP that then carries out this frequency measures after the adjacent area RSSI of different system adds Upper threshold; Otherwise, finish;

Concrete, those skilled in the art understand for the TD-CDMA system, with all the code channel RSCP on the time slot always less than carrier wave RSSI; After homologous ray adjacent area RSSI under certain frequency adds a constraint threshold value,, then think not have the adjacent area that is better than Serving cell under this frequency, then can not carry out PCCPCH RSCP measurement all adjacent areas this frequency under still less than Serving cell P-CCPCH RSCP; And if this RSSI adds after the constraint threshold value that greater than Serving cell P-CCPCH greater than RSCP, the adjacent area RSCP that then carries out this frequency measures, concrete available formula 1 expression:

$\left\{\begin{array}{c}({\mathrm{RSSI}}_i+{\mathrm{TH}}_{\mathrm{intra}-\mathrm{RAT}})<P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{scell}}\left(1\right)\\ ({\mathrm{RSSI}}_i+{\mathrm{TH}}_{\mathrm{intra}-\mathrm{RAT}})\&GreaterEqual;P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{scell}}\left(2\right)\end{array}\right.$

Wherein, at the adjacent area power measurement that does not carry out under the situation of (1) under the frequency i, at the adjacent area power measurement that carries out under the situation of (2) under the frequency i; RSSI in the formula _iBe the rssi measurement value of certain frequency of homologous ray, TH _Intra-RATBe homologous ray power constraint thresholding, this thresholding can have the actual demand of terminal to preestablish, generally greater than 0; P-CCPCH_RSCP _ScellBe Serving cell RSCP measured value; Can effectively reject the more weak sub-district of some signal powers by this method, promptly RSCP not carried out in this kind sub-district and measure, for free time has been flowed out in the measurement between system.

After the adjacent area RSSI of each frequency of different system adds a constraint threshold value,, then think not have the adjacent area that is better than Serving cell under this different system frequency, then synchro measure is not carried out in the adjacent area under this frequency still less than Serving cell P-CCPCH RSCP; If adding after the constraint threshold value, this RSSI then synchro measure is carried out in the adjacent area of this different system frequency, concrete available formula 2 expressions greater than Serving cell P-CCPCH RSCP:

$\left\{\begin{array}{c}({\mathrm{RSSI}}_i+{\mathrm{TH}}_{\mathrm{inter}-\mathrm{RAT}})<P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{scell}}\left(3\right)\\ ({\mathrm{RSSI}}_i+{\mathrm{TH}}_{\mathrm{intre}-\mathrm{RAT}})\&GreaterEqual;P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{scell}}\left(4\right)\end{array}\right.$

Wherein, at the adjacent area power measurement that does not carry out under the situation of (3) under the frequency i, at the adjacent area power measurement that carries out under the situation of (2) under the frequency i; RSSI in the formula _iBe the rssi measurement value of certain frequency of different system, TH _Inter-RATBe different system power constraint thresholding, this thresholding can have the actual demand of terminal to preestablish, generally greater than 0; P-CCPCH_RSCP _ScellBe Serving cell RSCP measured value;

In addition, can also determine whether that according to the magnitude relationship of adjacent area RSSI of different system and Serving cell P-CCPCH RSCP needs carry out the adjacent area synchronous detecting;

Concrete, adjacent area RSSI of more different system and homologous ray adjacent area P-CCPCH RSCP, after this RSSI adds a constraint thresholding in less than the homologous ray adjacent area during maximum P-CCPCH RSCP, then think not have the adjacent area that is better than the homologous ray adjacent area in the different system adjacent area, then synchro measure is not carried out in the adjacent area under this frequency; After adding a constraint thresholding, this RSSI in greater than the homologous ray adjacent area during maximum P-CCPCHRSCP, then synchro measure is carried out in the adjacent area of this different system frequency, concrete available formula 3 expressions:

$\left\{\begin{array}{c}({\mathrm{RSSI}}_i+{\mathrm{TH}}_{\mathrm{inter}-\mathrm{RAT}})<P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{scell}}\left(5\right)\\ {\mathrm{RSSI}}_i\&GreaterEqual;\mathrm{MAX}[P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{iScell}}-{\mathrm{TH}}_{\mathrm{Ninter}-\mathrm{TAT}},P-{\mathrm{CCPCH}\_\mathrm{RSCP}}_{\mathrm{fScell}}-{\mathrm{TH}}_{\mathrm{Ninter}-\mathrm{TAT}}]\left(6\right)\end{array}\right.$

Wherein, at the adjacent area power measurement that does not carry out under the situation of (5) under the frequency i, at the adjacent area power measurement that carries out under the situation of (6) under the frequency i; RSSI in the formula _iBe the rssi measurement value of certain frequency of different system, TH _Inter-RATBe different system adjacent area and another standard (homologous ray) adjacent area power deviation constraint thresholding, this thresholding can have the actual demand of terminal to preestablish, generally greater than 0; P-CCPCH_RSCP _ScellBe homologous ray sub-district RSCP measured value; Can pick out the adjacent area that to do further detection under effective different system frequency by this step.

As can be seen, adopt method of the present invention, can effectively reject some weak signal adjacent areas, and limited free time window is used to exist the measurement of potential target sub-district, to realize the system's measurements under the high speed business; Be furnished with the situation that a large amount of Timeslot ISCP measure for network, can reduce the synchronous detecting number of times of different system adjacent area, carry out the time slot interference power measurement to reserve these idle traffic time slots by this strategy; If be applied to holding state simultaneously, also can effectively reduce the nearby region measurement time under the holding state, thereby reach the purpose that reduces stand-by power consumption.
