Terminal check is in data transmission procedure; Target cell type and new controling parameters is increased in " Survey control (MeasurementControl) " signaling; New measurement report algorithm.Illustrate respectively below.
Terminal check is in the method in data transmission procedure.Such as, first terminal needs to be confirmed whether to be in " PMMCONNECTED " state, namely whether establishes PSSignalingConnection with network, in this way, then can think and be in data transmission procedure.It should be noted that, the present embodiment may be only applicable to the switching in data transmission procedure, be not suitable for the switching had in voice call or other circuit domain processes, so also need whether confirmation is current voice call or other circuit domain processes, terminal only needs to be confirmed whether to be in " MMCONNECTIONACTIVE " state, and namely rrc layer completes " security mode control (securitymodecontrol) process " or MM layer receives " CMSERVICEACCEPT " message.Terminal check is in " PMMCONNECTED " and after not being in " MMCONNECTIONACTIVE " state, then can initiate the measuring process described by the present embodiment.

Table 3
New measurement report algorithm.First, terminal sorts to dissimilar transport-type priority: priority from low to high successively: " R99 " (priority is 1) < " HSDPA " (priority is 2) < " HSUPA " (priority is 3) < " HSPA+ " (priority is 4) < " DC-HSPA " (priority is 5).The limit priority transport-type (R99, HSDPA, HSUPA, HSPA+ or DC-HSPA) that terminal is supported according to the type of current area, place and terminal in measuring process increases bias to the signal strength signal intensity (RSCP) of the dissimilar Target cell measured or signal quality (Ec/No) (determining according to the parameter in Survey control).Rule is as follows:
1. need use this new algorithm higher than the measurement target community measuring biased threshold parameter " Measurementthresholdfordatatransmission " to signal strength signal intensity or signal quality;
2. when the minimum priority in the maximum type priority and current service cell type priority level of terminal support is lower than the priority of the cell type measured, and terminal support maximum type priority higher than current service cell type priority level time, increase positive bias to the cell signal strength measured or signal quality;
3., when the minimum priority in the maximum type priority and current service cell type priority level of terminal support is higher than the cell type priority measured, increase negative bias to the cell signal strength measured or signal quality;
4. other situations, do not increase any bias to the cell signal strength measured or signal quality.
Measured and handover mechanism add terminal by the terminal of WCDMA network in the related in measuring process to the judgement of network type priority and process accordingly, make terminal can the higher community of report network type priority level as switching target small area, thus make network by terminal switch to the higher community of network type priority, make terminal obtain the higher data transmission performance of speed.
Below in conjunction with accompanying drawing, the preferred embodiment for the present invention is described.
Terminal carries out transfer of data in current service cell, and the limit priority transport-type of terminal support is " HSUPA ", and the type of current service cell is " HSDPA ".Terminal has confirmed to be in " PMMCONNECTED " state and not to be in " MMCONNECTIONACTIVE " state." Survey control (the MeasurementControl) " signaling issued according to network afterwards carries out measuring process.
In this preferred embodiment, the measurement target community that network issues in " Survey control (MeasurementControl) " signaling has 2, and first is " facing community 1 ", and its cell type is " R99 "; Second is " facing community 2 ", and its cell type is " HSUPA ".Measuring amount is signal strength signal intensity RSCP.The value measuring biased threshold parameter " Measurementthresholdfordatatransmission " is "-90dBm ".The value measuring bias " Measurementoffsetfordatatransmission " is 3dB.
When the Target cell signal strength signal intensity measured is higher than-90dBm, the method bringing into use the present invention to describe carries out measuring and reporting.Fig. 9 is the schematic diagram of the handoff procedure example according to the embodiment of the present invention, as shown in Figure 9.
The limit priority transport-type of terminal support is " HSUPA ", and namely priority is 3;
The type of current service cell is " HSDPA ", and namely priority is 2;
Face the cell type of community 1 for " R99 ", namely priority is 1;
Face the cell type of community 2 for " HSUPA ", namely priority is 3.
Minimum priority in the maximum type priority of computing terminal support and current service cell type priority level is 2, lower than the cell type priority 3 facing community 2, higher than the cell type priority 1 facing community 1.So, to the signal strength signal intensity RSCP value+3dB facing community 1 measured, to the signal strength signal intensity RSCP value-3dB facing community 2 measured, form the actual signal strength values used.Can see from figure, the serving cell signal intensity time constantly reduces, and community 1 " is faced " in measurement target community and the signal strength signal intensity of " facing community 2 " constantly increases in time.If do not adopt the present invention, just by traditional measurement and measurement report method, the signal quality of measurement target community is not biased, face the signal of community 1 higher than the signal facing community 2, switching target small area at time point B reporting measurement reports, " can be faced community 1 " and is reported to network by terminal, and network can by terminal switch to " facing community 1 ", because the cell type of " facing community 1 " is " R99 ", the message transmission rate of terminal can reduce.After adopting the present invention, the signal quality of measurement target community occurs biased, the signal " facing community 1 " is lower than the signal of " facing community 2 ", terminal can at time point A reporting measurement reports, community 2 " is faced " in switching target small area and is reported to network, network can by terminal switch to " facing community 2 ", and because the cell type of " facing community 2 " is " HSUPA ", the message transmission rate of terminal can not reduce.
