See also Fig. 1, Fig. 1 illustrates the functional block diagram according to the wireless terminal device and the wireless telecommunication system of a specific embodiment of the present invention.As shown in the figure, this wireless telecommunication system 1 comprises wireless terminal device 10, radio wide area network 12, WLAN 14 and core network end 16.In this specific embodiment, this wireless telecommunication system 1 is set in the FMC framework.
In practical application, this radio wide area network 12 can for, but be not subject to Global System for Mobile Communication (GSM) network or the third generation (3G) mobile communication network.In addition, this WLAN 14 can for, but be not subject to wireless authentication (Wireless fidelity, WiFi) network or blue bud network.
As shown in the figure, this core network end 16 connects this radio wide area network 12 and this WLAN 14 respectively.In addition, this wireless terminal device 10 comprises first mixed-media network modules mixed-media 100, second mixed-media network modules mixed-media 102, processing module 104 and man-machine interface 106.
This wireless terminal device 10 optionally communication connects this radio wide area network 12 or this WLAN 14.In reality, the communication context of this radio wide area network 12 and this wireless terminal device 10 is greater than the communication context of this WLAN 14 with this wireless terminal device 10, and can contain the communication context of this WLAN 14 and this wireless terminal device 10.
Say that further first mixed-media network modules mixed-media 100 of this wireless terminal device 10 can wirelessly connect the bridger (Access Point) in this WLAN 14, and detect first signal intensity value of above-mentioned bridger.Radio wide area network 12 has a base station in addition, and above-mentioned base station signal scope can contain the signal scope of the above-mentioned bridger of part at least, and 102 of second mixed-media network modules mixed-medias can be detected second signal intensity value of above-mentioned base station.
In addition, processing module 104 connects first mixed-media network modules mixed-media 100 and second mixed-media network modules mixed-media 102 respectively.In this specific embodiment, processing module 104 stores a plurality of communication modes, and the corresponding different compensation criterion of each communication mode.Please see table one in the lump, a plurality of communication modes in table one this specific embodiment with and the table of comparisons of corresponding compensation criterion.
The a plurality of communication modes of table one with and the table of comparisons of corresponding compensation criterion
| Communication mode | Compensation criterion |
| Wireless terminal device and WLAN communication context are enlarged | The 3rd signal intensity value=first signal intensity value+compensation default value |
| Wireless terminal device and WLAN communication context are reduced | The 3rd signal intensity value=first signal intensity value-compensation default value |
In this specific embodiment, man-machine interface 106 is available for users in these communication modes, select a target communication mode.And processing module 104 is to calculate the 3rd signal intensity value to compensation criterion that should the target communication mode.Shown in table; When compensation default value fixedly the time; In the communication mode that the WLAN communication context is enlarged, calculates and must the 3rd signal intensity value bigger, and in the communication mode that the WLAN communication context is reduced, calculate and must the 3rd signal intensity value less.

The term of this specification " communication quality " comprises, but is not subject to: speech quality, transmission rate and handover success rate.In other words, communication quality is good represents that speech quality is good, transmission rate is high, handover success rate is high; Speech quality is poor, transmission rate is low, handover success rate is low and the communication quality difference can be represented.
Wireless terminal device of the present invention can provide man-machine interface, the effective communication scope (being communication mode) that supplies the user to select institute's desire to use according to demand.For example; If the residing space of user is bigger, do not switch to radio wide area network too continually when not wanting again in this space, to move, can select effective communication scope C; Use letting wireless terminal device carry out communication through WLAN as far as possible, to reach purposes such as saving cost of the phone call.
Otherwise; If the user is higher for the demand of speech quality or transmission rate etc., do not hope to produce situations such as conversation or dialing failure, just can select effective communication scope A; Use let wireless terminal device and WLAN between signal intensity value arranged (for example when weakening slightly; The position is when the edge of effective communication scope A), just switch to radio wide area network, to keep communication quality.
Further, in this specific embodiment, suppose that the compensation default value is δ, and first signal intensity value in effective communication scope A, B, C is respectively α 1, α 2, α 3, and α 1 α 2 α 3., then the compensation criterion of corresponding these effective communication scopes A of the present invention, B, C can be respectively: the 3rd signal intensity value of effective communication scope A (κ 1) equals (first signal intensity value-δ); The 3rd signal intensity value of effective communication scope B (κ 2) equals first signal intensity value; And the 3rd signal intensity value of effective communication scope C (κ 1) equals (first signal intensity value+δ).

When wireless terminal device is among the effective communication scope A, the 3rd signal intensity value is (α 1-δ), and when wireless terminal device when moving among the effective communication scope B among the effective communication context A, the 3rd signal intensity value is (α 2-δ).Therefore, between (α 1-δ) and (α 2-δ), then when moving among the effective communication scope B among the certainly effective communication context A of wireless terminal device, the core network end just transmits switching command to wireless terminal device as if first pre-set threshold value.
Embodiment 2-user selects effective communication scope B
When wireless terminal device is among the effective communication scope A, the 3rd signal intensity value is α 1; When moving among the effective communication scope B among the certainly effective communication context A of wireless terminal device, the 3rd signal intensity value is α 2; And when moving among the effective communication scope C among the certainly effective communication context B of wireless terminal device, the 3rd signal intensity value is α 3.Therefore, between α 2 and α 3, then when wireless terminal device was arranged in effective communication scope A, B, the core network end did not transmit switching command as if first pre-set threshold value.And when the certainly effective communication context B of wireless terminal device moved among the effective communication scope C, the core network end just transmitted switching command.
Embodiment 3-user selects effective communication scope C
When wireless terminal device is among the effective communication scope A, the 3rd signal intensity value is (α 1+ δ); When moving among the effective communication scope B among the certainly effective communication context A of wireless terminal device, the 3rd signal intensity value is (α 2+ δ); And when moving among the effective communication scope C among the certainly effective communication context B of wireless terminal device, the 3rd signal intensity value is (α 3+ δ).Therefore, if first pre-set threshold value is less than (α 3+ δ), then when wireless terminal device is arranged in effective communication scope A, B, C, the neither transmission switching command of core network end.
According to another specific embodiment of the present invention, wireless terminal device of the present invention also can be set corresponding switching threshold values according to aforesaid effective communication scope.For example, wireless terminal device predeterminable compensation threshold values ε and the preset threshold values λ that switches.Further, when the user selects effective communication scope A, set the actual threshold values that switches and equal (λ+ε); When the user selects effective communication scope B, set the actual threshold values that switches and equal λ; And when the user selects effective communication scope C, set the actual threshold values that switches and equal (λ-ε).According to the standard of 3GPP, find first signal intensity value when wireless terminal device and just start changeover program when being lower than actual switching threshold values.Therefore, the user starts changeover program (because corresponding actual switch threshold values the highest) the most easily when selecting effective communication scope A, and the user starts changeover program (because corresponding actual switch threshold values minimum) when selecting effective communication scope C least easily.
