Embodiment
Below, describe embodiments of the invention in detail with reference to accompanying drawing.
Fig. 1 is a block diagram of realizing the dual-mode terminal 100 of sub-district gravity treatment according to an exemplary embodiment of the present invention.With reference to Fig. 1, dual-mode terminal 100 comprises measuring unit 101, receiving element 102 and processing unit 103 according to an exemplary embodiment of the present invention.
Receiving element 102 indicates the gravity treatment decision threshold to satisfy the information that the relative parameter criterion still satisfies the absolute reference criterion from the broadcast reception of GSM sub-district.Here, term " gravity treatment decision threshold " reselects to the foundation of TD-SCDMA sub-district as dual-mode terminal 100 from the GSM sub-district, can be handed down to dual-mode terminal in the broadcast of GSM sub-district, and can be disposed by operator.
This indication gravity treatment decision threshold satisfies the information that the relative parameter criterion still satisfies the absolute reference criterion can constitute a set collection, and described set collection can be divided into two subclass.The sub-set representations that described set is concentrated and the set of the pairing information of relative parameter, another subclass is represented the set with the pairing information of absolute reference.Preferably, this indication gravity treatment decision threshold satisfies the length that the relative parameter criterion still satisfies the information of absolute reference criterion and can be 4 bits.Be meant operator's configuration corresponding to the relative parameter of this gravity treatment decision threshold and absolute reference with the corresponding signal strength values of gravity treatment decision threshold.
Here, if described information indication gravity treatment decision threshold satisfies the absolute reference criterion, then reselection conditions be the TD-SCDMA cell signal strength at the fixed time during the section greater than described gravity treatment decision threshold.If described information indication gravity treatment decision threshold satisfies the relative parameter criterion, then reselection conditions be between TD-SCDMA cell signal strength and the GSM cell signal strength difference at the fixed time during the section greater than described gravity treatment decision threshold.Here, the predetermined amount of time in the described reselection conditions can be the interior random time section of zone of reasonableness of system configuration, and preferably, the predetermined amount of time in reselection conditions can be 5 seconds.Just, if judge that in gravity treatment thresholding satisfies TD-SCDMA cell signal strength under the situation of absolute reference criterion and arrives 5 seconds greater than duration of described gravity treatment decision threshold, arrive 5 seconds if perhaps satisfy the difference between the TD-SCDMA cell signal strength and GSM cell signal strength under the situation of relative parameter criterion at the gravity treatment decision threshold greater than duration of described gravity treatment decision threshold, then processing unit 103 will reselect to the TD-SCDMA sub-district.The operation of dual-mode terminal 100 is according to an exemplary embodiment of the present invention described below for example.
Suppose that the TD-SCDMA cell signal strength that measuring unit 101 is measured is R1, the signal strength signal intensity of this sub-district of GSM is R2.If the information that receiving element 102 receives satisfies the relative parameter criterion, then processing unit 103 compares difference between R1 and the R2 and gravity treatment decision threshold (TDD-offset).Then, processing unit 103 judges that whether the difference between R1 and the R2 satisfies and the corresponding reselection conditions of relative parameter criterion, that is, described difference whether at the fixed time during the section greater than TDD-offset.If described difference at the fixed time the section during greater than TDD-offset, then processing unit 103 reselects to the TD-SCDMA sub-district.On the other hand, if the information that receiving element 102 receives satisfies the absolute reference criterion, then processing unit 103 compares TD-SCDMA cell signal strength R1 and TDD-offset.Then, processing unit 103 judges that whether R1 satisfies and the corresponding reselection conditions of absolute reference criterion, that is, R1 whether at the fixed time during the section greater than TDD-offset.If R1 at the fixed time the section during greater than TDD-offset, then processing unit 103 reselects to the TD-SCDMA sub-district.
Following table 1 illustrates the relation between TDD-offset and relative parameter X and the absolute reference Y and the example of cell reselection processing method.
Table 1
In table 1, TDD-offset is that odd number value is represented to that is to say that according to the configuration of absolute reference criterion when system configuration TDD-offset was odd number value, dual-mode terminal 100 carried out the sub-district gravity treatment according to the absolute reference value of table 1.TDD-offset is that even number value represents that promptly, when TDD-offset was even number value, dual-mode terminal 100 carried out the sub-district gravity treatment according to the relative parameter of table 1 according to the configuration of relative parameter criterion.
Here, value that can TDD-offset is set to 4 bits, that is, when configuration TDD-offset value was even number value, the value of TDD-offset was 0000,0010,0100,0110,1000,1010,1100,1110.At this moment, dual-mode terminal 100 with its be interpreted as relative parameter Xn (n=1,2 ..., 8), R1 that measures when terminal during the section at the fixed time and the difference of R2 are during greater than Xn, dual-mode terminal 100 reselects to the TD-SCDMA sub-district.Yet when configuration TDD-offset value was odd number value, the value of TDD-offsct was 0001,0011,0101,0111,1001,1011,1101,1111.Dual-mode terminal 100 with its be interpreted as absolute reference Yn (n=1,2 ..., 8), the R1 that measures when terminal during the section at the fixed time is during greater than this absolute reference Yn, dual-mode terminal 100 reselects to the TD-SCDMA sub-district.
It should be noted that this only is an example, those skilled in the art should know can also a lot of other alternative.For example, can be set to even number value (that is, 0000,0010,0100 by TDD-offset, 0110,1000,1010,1100,1110) expression is disposed according to the absolute reference criterion, dual-mode terminal 100 with its be interpreted as absolute reference Yn (n=1,2 ..., 8), and TDD-offset is set to odd number value (promptly, 0001,0011,0101,0111,1001,1011,1101,1111) expression is disposed according to the relative parameter criterion, dual-mode terminal 100 with its be interpreted as relative parameter Xn (n=1,2 ..., 8).Perhaps, a certain median (for example, 0111) can be set also, when TDD-offset is less than or equal to this median 0111 according to absolute reference criterion configuration, when TDD-offset disposes according to the relative parameter criterion during greater than this median 0111.Those skilled in the art can select according to the real network situation for concrete parameter configuration.
Fig. 3 is the flow chart of residence reselecting according to an exemplary embodiment of the present invention.
With reference to Fig. 3, at step S201, measuring unit 101 is measured TD-SCDMA sub-district and GSM cell signal strength.After dual-mode terminal 100 starts, dual-mode terminal 100 initially resides in the GSM sub-district according to signal conditioning according to an exemplary embodiment of the present invention, and measuring unit 101 carries out the measurement of cell signal strength simultaneously.When the signal strength signal intensity of the GSM sub-district that measuring unit 101 measures reached certain measurement threshold value, measuring unit 101 can begin the measurement to the TD-SCDMA cell signal strength, wherein, the measurement threshold value is set when configuration-system.
In step 202, receiving element 102 satisfies the information that the relative parameter criterion still satisfies the absolute reference criterion from the broadcast reception indication gravity treatment decision threshold of GSM sub-district.Here, term " gravity treatment decision threshold " reselects to the foundation of TD-SCDMA sub-district as dual-mode terminal 100 from the GSM sub-district, can be handed down to dual-mode terminal in the broadcast of GSM sub-district, and can be disposed by operator.
This indication gravity treatment decision threshold satisfies the information that the relative parameter criterion still satisfies the absolute reference criterion can constitute a set collection, and described set collection can be divided into two subclass.The sub-set representations that described set is concentrated and the set of the pairing information of relative parameter, another subclass is represented the set with the pairing information of absolute reference.Preferably, this indication gravity treatment decision threshold satisfies the length that the relative parameter criterion still satisfies the information of absolute reference criterion and can be 4 bits.Be meant operator's configuration corresponding to the relative parameter of this gravity treatment decision threshold and absolute reference with the corresponding signal strength values of gravity treatment decision threshold.
In step 203, processing unit 103 judges that satisfying the relative parameter criterion from the described information indication gravity treatment decision threshold of receiving element 102 receptions still is the absolute reference criterion.If in step 203, the judged result of processing unit 103 satisfies the relative parameter criterion for the gravity treatment decision threshold, then in step 204, processing unit 103 compares difference between TD-SCDMA cell signal strength and the GSM cell signal strength and described gravity treatment decision threshold, judges whether described difference satisfies and the corresponding reselection conditions of relative parameter criterion.If in step 204, described difference satisfies and the corresponding reselection conditions of relative parameter criterion, then reselects to the TD-SCDMA sub-district in step 205.That is to say, in step 204, the difference between TD-SCDMA cell signal strength and the GSM cell signal strength at the fixed time the section during greater than described gravity treatment decision threshold, then in step 206, processing unit 103 reselects to the TD-SCDMA sub-district.
If in step 203, the judged result of processing unit 103 satisfies the absolute reference criterion for the gravity treatment decision threshold, then in step 205, processing unit 103 compares TD-SCDMA cell signal strength and described gravity treatment decision threshold, judges whether the TD-SCDMA cell signal strength satisfies and the corresponding reselection conditions of absolute reference criterion.If in step 205, the TD-SCDMA cell signal strength satisfies and the corresponding reselection conditions of absolute reference criterion, then in step 206, reselects to the TD-SCDMA sub-district.That is to say, if in step 205, the TD-SCDMA cell signal strength at the fixed time the section during greater than described gravity treatment decision threshold, then in step 206, processing unit 103 reselects to the TD-SCDMA sub-district.
Here, the predetermined amount of time in the described reselection conditions can be the interior random time section of zone of reasonableness of system configuration, and preferably, the predetermined amount of time in reselection conditions can be 5 seconds.Just, if judge that in gravity treatment thresholding satisfies TD-SCDMA cell signal strength under the situation of absolute reference criterion and arrives 5 seconds greater than duration of described gravity treatment decision threshold, arrive 5 seconds if perhaps satisfy the difference between the TD-SCDMA cell signal strength and GSM cell signal strength under the situation of relative parameter criterion at the gravity treatment decision threshold greater than duration of described gravity treatment decision threshold, then processing unit 103 will reselect to the TD-SCDMA sub-district.
Below, by using concrete example exemplary embodiment of the present is described.
Below table 2 illustrate for absolute reference with-102dBm is a starting point, relative parameter is the processing to this parameter of the use of parameter configuration of starting point and dual-mode terminal with-28dBm.
Table 2
In table 2, when TDD-offset was configured to even number value, promptly TDD-offset was 0000,0010,0100,0110,1000,1010,1100,1110, dual-mode terminal 100 is interpreted as that with it TDD-offsct satisfies the relative parameter criterion, and when the difference of TD-SCDMA cell signal strength of measuring and GSM cell signal strength at the fixed time during the section greater than relative parameter (32dBm,-24dBm,-16dBm ,-8dBm, 0dBm, 8dBm, 16dBm, in the time of 24dBm), dual-mode terminal 100 reselects to the TD-SCDMA sub-district.
When TDD-offset was configured to odd number value, promptly the value of TDD-Qoffset was 0001,0011,0101,0111,1001,1011,1101,1111, dual-mode terminal 100 is interpreted as that with it TDD-offset satisfies the absolute reference criterion, and when the TD-SCDMA cell signal strength of measuring at the fixed time during the section greater than absolute reference (102dBm ,-96dBm ,-90dBm,-84dBm ,-78dBm ,-72dBm,-66dBm ,-60dBm) time, dual-mode terminal 100 reselects to the TD-SCDMA sub-district.
It should be noted that this only is an example, those skilled in the art should know can also a lot of other alternative.For example, can be set to even number value (that is, 0000,0010,0100 by TDD-offset, 0110,1000,1010,1100,1110) expression is disposed according to the absolute reference criterion, dual-mode terminal 100 with its be interpreted as absolute reference Yn (n=1,2 ..., 8), and TDD-offset is set to odd number value (promptly, 0001,0011,0101,0111,1001,1011,1101,1111) expression is disposed according to the relative parameter criterion, dual-mode terminal 100 with its be interpreted as relative parameter Xn (n=1,2 ..., 8).Perhaps, a certain median (for example, 0111) can be set also, when TDD-offset is less than or equal to this median 0111 according to absolute reference criterion configuration, when TDD-offset disposes according to the relative parameter criterion during greater than this median 0111.Those skilled in the art can select according to the real network situation for concrete parameter configuration.
