Need to prove, when the signal quality of assistant carrier frequency is lower than threshold value, also can not carry out the flow process that non-use carrier frequency is measured.
Step 205: the measurement control messages that non-use carrier frequency is measured that receives that network side sends.
Step 206: transceiver is measured non-use carrier frequency.
Because terminal is when measuring non-use carrier frequency, follow the principle that a carrier frequency can not be measured by a plurality of transceivers, this principle is for fear of a plurality of transceivers same non-use carrier frequency to be measured, thereby causes the duplicate measurements to this non-use carrier frequency.Therefore, each transceiver of terminal all can not measured using carrier frequency, but a non-use carrier frequency can only be measured by a transceiver in a period of time, that is to say, in a period of time, can only measure all non-use carrier frequency with a transceiver, if promptly terminal has idle transceiver, then in idle transceiver, select one non-use carrier frequency measured, if terminal does not have idle transceiver, then select a transceiver that is using, behind the startup compact model non-use carrier frequency is measured.

Embodiment three
Present embodiment provide based on the flow process of the measurement report method of multicarrier as shown in Figure 4, present embodiment will be in conjunction with being described at dual carrier HSDPA system applies scene as shown in Figure 3, in the networking structure schematic diagram shown in Figure 3, terminal is the terminal with multi-carrier capability, the frequency of sub-district 1 and sub-district 3 is f1, the frequency of sub-district 2 and sub-district 4 is f2, sub-district 1 (f1 is a main carrier frequency) and sub-district 2 (f2 is an assistant carrier frequency) are carried out the multicarrier pairing, the multicarrier pairing is carried out in sub-district 3 and sub-district 4, the right sub-district of above-mentioned two assembly is applied among the descending HS-DSCH, belong to same base station, and use same transmit antennas.Describe when being applied in the inventive method embodiment in the dual carrier HSDPA system process that the terminal measurement reports below in detail:
Step 401: accessing terminal to network.
Step 402: network side sends to terminal and measures control messages, for example MeasurementControl.
Network side can increase the domain of dependence in this Measurement Control message, be used to identify following information: the main carrier frequency that terminal is used; For main carrier frequency and the assistant carrier frequency that terminal is used, construct a common frequency measurement cell respectively; Indicate the frequency of common frequency measurement; The sub-district of not using carrier frequency is put into the different-frequency measure cell list.
Concrete, in the main carrier frequency cell (for example PrimaryFrequency) of Measurement Control message, fill the information of main carrier frequency f1, measuring two cells of cell (for example intra-frequency measurement) in having frequently among f1 and the f2 respectively distinguishes by carrier frequency information f1 and f2, the wherein tabulation of the cell measurement in the intra-frequency measurement cell of f2, the Serving cell that for example only comprises f2 among the cells for measurement, and only carry out reporting of inter-frequency measurement incident, and do not carry out reporting of frequently interior measurement event; Only comprise 2a, 2d, 2f incident in the inter-frequency measurement reporting event cell in inter-frequency measurement cell (for example inter-frequency measurement) (for example inter-frequency measurement reporting criteria).
Step 403: terminal is carried out in the frequency and inter-frequency measurement according to the content that the domain of dependence in the measurement control messages that receives increases to main carrier frequency and the assistant carrier frequency that is using.
After terminal receives Measurement Control message, measure the main carrier frequency sub-district of main carrier frequency f1 correspondence and the assistant carrier frequency sub-district of assistant carrier frequency f2 correspondence respectively by two transceivers.
Wherein, main carrier frequency f1 reported event rule is measured with in having now frequently, the inter-frequency measurement rule is identical, promptly the signal quality according to sub-district 1 reports 1x incident, 2d incident and 2f incident, carry out for network side Active Set maintenance, best cell maintenance and start not using the measurement of carrier frequency.
Assistant carrier frequency f2 reports 2d incident and 2f incident according to the signal quality of sub-district 2, is used for assistant carrier frequency is added and deletes.Because assistant carrier frequency has only the HSDPA relevant link, does not need to safeguard Active Set, therefore needn't report 1a incident, 1b incident and 1c incident.Because in the existing dual carrier HSDPA system, the main carrier frequency Serving cell and the assistant carrier frequency Serving cell of pairing can only use an antenna, and an antenna can not be launched two cell signals on a carrier frequency, therefore the main carrier frequency Serving cell can not occur remains unchanged, and assistant carrier frequency carries out the situation with the affair cell update that is taken in small doses at short intervals, so assistant carrier frequency f2 needn't report the 1d incident.
Step 404: terminal triggers measurement event according to different measurement results and reports.
Carry out giving the correct time on the measurement report after measurement event triggers, the signal quality that reports all to use the sub-district of carrier frequency at least promptly report main carrier frequency f1 to go up the sub-district of measuring at least, and assistant carrier frequency f2 goes up the signal quality of the sub-district of measuring.
Wherein, measurement event in main carrier frequency f1 reports frequently according to frequently interior measurement result is done the renewal of Active Set maintenance and Serving cell for main carrier frequency.If among main carrier frequency f1 and the assistant carrier frequency f2 preferably carrier frequency variation has taken place, then report the 2a incident, comprise the information of new best carrier frequency and the information of best carrier frequency last time in the corresponding measurement report; When the signal quality of main carrier frequency f1 or assistant carrier frequency f2 is lower than certain thresholding, report the 2d incident; When the signal quality of main carrier frequency f1 or assistant carrier frequency f2 is higher than certain thresholding, report the 2f incident.
Step 405: network side confirms that the terminal main carrier frequency has reported the 2d incident.
Step 406: network side issues measurement control messages at the 2d incident to terminal.
Since terminal to report at the 2d incident of main carrier frequency f1, this moment, the signal quality of main carrier frequency f1 was lower than certain thresholding, so network side issues new measurement control messages to terminal, the requesting terminal is measured non-frequency of utilization.Simultaneously, interior frequently the measurement remains unchanged.
Concrete, comprise 2a incident, 2b incident, 2c incident, 2d incident and 2f incident in the inter-frequencyreporting criteria cell in inter-frequency measurement cell, the scope of the non-use carrier cell of measurement is not limited to the Serving cell 2 with 1 pairing of main carrier frequency f1 Serving cell.
Step 407: terminal is carried out the measurement of non-frequency of utilization according to the measurement control messages of receiving.
After terminal is received Measurement Control message, measure the main carrier frequency sub-district of main carrier frequency f1 correspondence and the assistant carrier frequency sub-district of assistant carrier frequency f2 correspondence respectively by two transceivers.
Terminal can start compact model on the transceiver of the transceiver of main carrier frequency f1 correspondence or assistant carrier frequency f2 correspondence, non-use carrier frequency is measured.Because each transceiver of FDD system can only be operated on the carrier frequency a moment,, will start compact model therefore if use this transceiver to measure the signal of other carrier frequency.And, because a carrier frequency does not allow to be measured by a plurality of transceivers in a period of time, to avoid being repeated measurement.Therefore, when carrying out the measurement of non-use carrier frequency, can only use a transceiver to carry out the measurement of all non-use carrier frequency, promptly non-use carrier frequency be measured by one in main carrier frequency f1 transceiver or the assistant carrier frequency f2 transceiver; Also can measure different non-use carrier frequency simultaneously with assistant carrier frequency f2 transceiver, need guarantee during measurement same non-use carrier frequency not to be carried out duplicate measurements by main carrier frequency f1 transceiver.
Step 408: terminal triggers the inter-frequency measurement reporting events according to the measurement result of non-use carrier frequency.
Terminal reports 2b incident and 2c incident according to the measurement result to non-use carrier frequency to network side.Simultaneously, terminal can also report the inter-frequency measurement incident of corresponding main carrier frequency f1 and assistant carrier frequency f2 to network side, comprises 2a incident, 2d incident, 2f incident etc.
As seen from the above-described embodiment, terminal can carry out all assistant carrier frequencies that using measuring in the frequency, network side can be safeguarded according to the measurement result pair information relevant with assistant carrier frequency of assistant carrier frequency, has improved the accuracy of the network side in the multicarrier system to the judgement of end side mobility.
Embodiment four
The embodiment of the invention can also be applied in uplink and downlink and be in the system of multicarrier except being applied in the dual carrier HSDPA system, for example, a descending m carrier wave, the scene of a up n carrier wave, wherein, m greater than 2, n is greater than 2, and m is more than or equal to n.As shown in Figure 5, present embodiment is described in detail when being applied in the inventive method embodiment in the multicarrier system, the process that the terminal measurement reports.In this multicarrier system, can have a plurality of with the assistant carrier frequency of main carrier frequency pairing, uplink and downlink all have the auxilliary carrier wave of paired carrier frequency need safeguard Active Set, also should have a plurality of mutually with the assistant carrier frequency Serving cell of main carrier frequency Serving cell pairing, therefore present embodiment is with the different of embodiment three, needs assistant carrier frequency to report the 1x incident.
Step 501: accessing terminal to network.
Step 502: network side sends to terminal and measures control messages, for example MeasurementControl.
The frequency point information that comprises main carrier frequency in this measurement control messages; All have in the frequency for main carrier frequency and each assistant carrier frequency and to measure cell; In each frequency, measure in the cell and indicate carrier frequency information; The sub-district of not using carrier frequency is write the inter-frequency measurement cell list.
Need to prove, in order to optimize measuring process, network side can reduce useless measurement according to the multi-carrier district pair relationhip, promptly in measuring control messages, only comprise the assistant carrier frequency Serving cell that matches with the main carrier frequency Serving cell in the measurement cell list of assistant carrier frequency, and do not comprise other unpaired assistant carrier frequency Serving cell.
If when the incident that assistant carrier frequency triggers is carried out the mobility judgement and do not influenced network side, in measuring control messages, also be provided with and do not report corresponding event.For example,, on assistant carrier frequency, have only the HSDPA channel,, therefore 1a incident, 1b incident, the 1c incident of not reporting can be set in measuring control messages because the HSDPA channel does not need to safeguard Active Set when main carrier frequency of the up use of terminal; If two incidents trigger simultaneously or the interval of trigger event during less than certain thresholding, require measurement result with two incidents to be placed in the measurement report and send, reduce the measurement report that reports with this.
Step 503: terminal carries out measuring and inter-frequency measurement in the frequency to main carrier frequency and the assistant carrier frequency that is using.
Main carrier frequency carries out measuring and inter-frequency measurement in the frequency, and promptly the signal quality according to the main carrier frequency sub-district reports 1x incident, 2d incident and 2f incident, carries out the maintenance of Active Set for network side, the maintenance of best cell and start the not measurement of frequency of utilization.
Assistant carrier frequency carries out measuring and inter-frequency measurement in the frequency equally, and promptly the signal quality according to the assistant carrier frequency sub-district reports 1x incident, 2d incident and 2f incident, carries out the measurement of not using carrier frequency with startup of Active Set maintenance, best cell for network side.
Step 504: terminal reports the measurement report that comprises measurement result to network side.
After the carrier cell that the needs of measuring appointment in the control messages are measured is measured, comprise events corresponding and the carrier frequency corresponding in the measurement report with this incident.Wherein, 1x incident, 2d incident and 2f incident only use carrier frequency relevant with each; The 2b incident is relevant with certain non-use carrier frequency with each carrier frequency that is using; The 2c incident is relevant with non-use carrier frequency; The 2a incident is relevant with a non-best carrier frequency that will replace this best carrier frequency with current best carrier frequency, and the carrier frequency that wherein will replace best carrier frequency can be the carrier frequency that is using, and also can be non-use carrier frequency.
Concrete, in the frequency that comprises the carrier cell measurement result that terminal using, in the measurement result tabulation (for example intra-frequency measured results list), increase carrier frequency information, in order to distinguish carrier frequency and the untapped carrier frequency that is using; In inter-frequency measurement event result (for example inter-frequency measurement event results), increase the information that triggers carrier frequency.Because a plurality of assistant carrier frequencies are arranged, therefore also need in frequently, increase the information that triggers carrier frequency among the measurement event result (for example intra-frequency measurement event results), wherein, for the 2a incident, in the information that triggers carrier frequency, write original best carrier frequency; For the 2b incident, in the information that triggers carrier frequency, write certain carrier frequency that is using, this carrier frequency is lower than certain thresholding; For 2c, 2d and 2f incident, in the information that triggers carrier frequency, do not write any carrier frequency.
If comprise the 2d incident in the measurement report of terminal to report, network side also needs to issue the measurement control messages that non-use carrier frequency is measured to terminal, and its process is consistent with embodiment three, does not repeat them here.
As seen from the above-described embodiment, terminal in the multicarrier system can carry out measuring in the frequency to main carrier frequency and all assistant carrier frequencies that using, network side can be safeguarded according to the measurement result pair information relevant with assistant carrier frequency of assistant carrier frequency, has improved the accuracy of network side to the judgement of end side mobility.
