New measurement report algorithm.Firstly, terminal is ranked up different type transport-type priority: priority is from lowBe successively to height: " R99 " (priority 1) < " HSDPA " (priority 2) < " HSUPA " (priority 3) < " HSPA+ " is (excellent4) < " DC-HSPA " (priority 5) first grade is.Terminal is in measurement process according to the type of place current area and terminal instituteThe highest priority transport-type (R99, HSDPA, HSUPA, HSPA+ or DC-HSPA) of support is come to the different type measuredThe signal strength (RSCP) or signal quality (Ec/No) (being determined according to the parameter in measurement control) of Target cell, which increase, to be biasedValue.Rule is as follows:
1. measurement biasing threshold parameter " Measurement threshold need to be higher than to signal strength or signal qualityThe measurement Target cell of for data transmission " uses this new algorithm；
2. when the minimum priority in the maximum type priority and current service cell type priority grade that terminal is supported is lowIn the priority of the cell type measured, and the maximum type priority that terminal is supported is higher than current service cell type priorityWhen grade, increase positive bias to the cell signal strength or signal quality measured；
3. when the minimum priority in the maximum type priority and current service cell type priority grade that terminal is supported is highWhen the cell type priority measured, increase negative bias to the cell signal strength or signal quality measured；
4. other situations do not increase any bias to the cell signal strength or signal quality that measure.
By increasing terminal in measurement process on the terminal measurement of WCDMA network in the related art and handover mechanismJudgement and corresponding processing to network type priority, so that terminal can be made with the higher cell of report network type priority gradeTerminal is set to obtain rate so that network be made to switch the terminal into the higher cell of network type priority for switching target small areaHigher data transmission performance.
The preferred embodiment for the present invention is illustrated with reference to the accompanying drawing.
Terminal carries out data transmission in current service cell, and the highest priority transport-type that terminal is supported is " HSUPA ",The type of current service cell is " HSDPA ".Terminal has confirmed that in " PMM CONNECTED " state and is not at " MMCONNECTION ACTIVE " state." measurement control (Measurement the Control) " signaling issued later according to networkMeasure process.
In this preferred embodiment, measurement that network issues in " measurement control (Measurement Control) " signalingTarget cell has 2, and first is " facing cell 1 ", and cell type is " R99 "；Second is " facing cell 2 ", cell classType is " HSUPA ".Measurement amount is signal strength RSCP.Measurement biasing threshold parameter " Measurement threshold forThe value of data transmission " is " -90dBm ".Measure bias " Measurement offset for dataThe value of transmission " is 3dB.
When the Target cell signal strength measured is higher than -90dBm, the method for beginning to use the present invention to describe is surveyedAmount and report.Fig. 9 is the schematic diagram of handoff procedure example according to an embodiment of the present invention, as shown in Figure 9.
The highest priority transport-type that terminal is supported is " HSUPA ", i.e., priority is 3；
The type of current service cell is " HSDPA ", i.e., priority is 2；
The cell type for facing cell 1 is " R99 ", i.e., priority is 1；
The cell type for facing cell 2 is " HSUPA ", i.e., priority is 3.
Computing terminal support maximum type priority and current service cell type priority grade in minimum priority be2, lower than the cell type priority 3 for facing cell 2, higher than the cell type priority 1 for facing cell 1.So facing what is measuredThe signal strength RSCP value+3dB of cell 1 forms actual use to the signal strength RSCP value -3dB for facing cell 2 measuredSignal strength indication.From the figure it may be seen that serving cell signal intensity constantly reduces at any time, measurement Target cell " faces smallThe signal strength of area 1 " and " facing cell 2 " constantly increase at any time.If not using the present invention, only with traditional measurement and surveyMethod for reporting is measured, the signal quality for measuring Target cell does not bias, and the signal for facing cell 1 is higher than the signal for facing cell 2, terminalIt can report that network can switch the terminal into network for switching target small area " facing cell 1 " in time point B reporting measurement reports" facing cell 1 ", since the cell type of " facing cell 1 " is " R99 ", the message transmission rate of terminal can be reduced.Using the present inventionAfterwards, the signal quality for measuring Target cell biases, and the signal of " facing cell 1 " is lower than the signal of " facing cell 2 ", and terminal can beSwitching target small area " facing cell 2 " is reported that network, which can switch the terminal into, " to be faced small to network by time point A reporting measurement reportsArea 2 ", since the cell type of " facing cell 2 " is " HSUPA ", the message transmission rate of terminal will not be reduced.
