         [0018]    Referring to  FIG. 2  and to  FIG. 3 ˜ FIG. 7  simultaneously, the implementation method S 1  will be described as below. 
         [0019]    (1) Buying Group Establishment Step S 11 : 
         [0020]    As shown in  FIG. 3 , when an user intends to initiate group purchase activity, the user needs to execute a group-purchase application program of the mobile communication device  12  and further input at least one device identification code (such as a phone number) of another mobile communication device ( 12 ′,  12 ″ . . . ) through the buying group establishment module  121 . Upon completion of the input, the mobile communication device  12  sends an invitation I of the buying group to a plurality of second mobile communication devices ( 12 ′,  12 ″ . . . ) through the group purchase information transmitting module  123 . When the second mobile communication device ( 12 ′,  12 ″ . . . ) executes the group-purchase application program and accepts the invitation, the mobile communication device  12  and each of the second mobile communication device ( 12 ′,  12 ″ . . . ) will report to the group-purchase server  11  so that the group-purchase member record unit  1111  of the group-purchase server  11  can execute member&#39;s identity authentication. After the authentication is completed, the buying group recording module  112  then records the mobile communication device  12  and the invited second mobile communication device ( 12 ′,  12 ″ . . . ) in an original buying group. 
         [0021]    (2) Group-Purchase Information Establishment Step S 12 : 
         [0022]    As shown in  FIG. 4 , when the original buying group is established, the creator of the original buying group can edit a group-purchase information P through the group-purchase information establishment module  122  of the mobile communication device  12 . The group-purchase information P includes at least one first price Ps of commodity, further includes commodity name, buy time, consignment address or commodity introduction, etc., or the other information related to group-purchase commodity, such as commodity pictures, commodity trial articles, commodity composition information, etc., what&#39;s more, the group-purchase information P can includes different types of commodity options and product websites, etc., but is not limited to this. 
         [0023]    (3) Group-Purchase Information Sending Step S 13 : 
         [0024]    As shown in  FIG. 5 , when the group-purchase information P is established, it can be displayed on the interface of the group-purchase program application of the mobile communication device  12 . The mobile communication device  12  can establish a plurality of group-purchase information P, then the mobile communication device  12  can select one of the purchase information P and send the selected group-purchase information P to the original buying group through the group-purchase information transmission module  123  so that all the second mobile communication devices ( 12 ′,  12 ″ . . . ) can receive the selected group-purchase information P, and then conduct commodity orders through the respective second mobile communication devices ( 12 ′,  12 ″ . . . ). When the mobile communication device  12  transmits the group-purchase information P to the second mobile communication devices ( 12 ′,  12 ″ . . . ), the mobile communication device  12  simultaneously transmits the group-purchase information P to the group-purchase server  11  and stores it in the group-purchase commodity record unit  1112 . 
         [0025]    (4) Extended Sub-Group Establishment Step S 14 : 
         [0026]    As shown in  FIG. 6 , the implementing step comprises the following: 
         [0027]    (4-1) Step of Submitting a Request to Create a Sub-Group S 141 : 
         [0028]    When user wants to establish an extended sub-group, the second mobile communication device  12 ′ in the original buying group executes a group extension modules  124 ′ to send an extended sub-group establishment request to the group-purchase server  11 . 
         [0029]    (4-2) Step of Sending an Extension Buying Group Invitation S 142 : 
         [0030]    As shown in  FIG. 6 a   , when the group-purchase server  11  receives the request, the buying group establishment module  121 ′ of the mobile communication device  12 ′ can send a buying group invitation I through the group-purchase information transmission module  123 ′ to the other mobile communication devices that have not yet joined the original buying group. The buying group recording module  112  of the group purchase server  11  can synchronously establish and record the second mobile communication device  12 ′ and the other invited mobile communication devices in the extended sub-group. 
         [0031]    (4-3) Commodity Price Re-Set Step S 143 : 
         [0032]    Referring to  FIGS. 6 b -6 c   , when the extended sub-group has been created, the original buying group and the extended sub-group are in information linking together, so that group-purchase information establishment module  122 ′ of the second mobile communication device  12 ′ can retrieve the group-purchase information P in the original buying group and request the second mobile communication device  12 ′ to reset the first price Ps of the commodity. After the completion of the price-resetting, a second group-purchase information P′ and a second price Ps&#39; of commodity are generated which are then sent to the mobile communication device in the extended sub-group (e.g.,  FIG. 6 c   ) for the other mobile communication devices in the extended sub-group to make order of commodity. The group-purchase server  11  may limit the condition for setting the second price Ps&#39; of commodity and the members of the extended group, for example, the second price Ps&#39; of commodity should be higher than the first price Ps of commodity or the members of the original buying group should not be re-invited into the extended sub-group. In this manner, limiting the commodity price will be able to avoid the loss of the sub-group creator caused by the incoming price to be lower than sale price, while limiting the extended sub-group members will be able to avoid the entry of the participants of the original buying group into the extended sub-group, resulting in the situation of stagnation on commodity sales. 
         [0033]    (4-4) Spread Profit Feedback Step S 144 : 
         [0034]    As shown in  FIG. 7 , when the group-purchase activity is ended, the reward calculation unit  1113  of the group-purchase server  11  will calculate a spread profit by comparing between the first price and the second price of commodity. In other words, the spread profit is the amount of subtracting the second commodity price Ps&#39; from the first commodity price Ps first and then multiplying by the order quantity. After calculating the spread profit, the reward calculation unit  1113  returns the spread profit back to the second mobile communication device  12 ′ which creates the extended buying sub-group. Members of the extended sub-group can also be allowed to create extended sub-group again, the creating process and the spread profit feedback process are described in buying group establishment step S 11 ˜extended sub-group establishment step S 14 , hence description is omitted herein. 
         [0035]    Referring to  FIG. 8  and continuing from  FIGS. 1 to 7 , the mobile group-purchase system of the present invention can set up reward condition for feedback incentive. For example, the commodity price is fixed after the original buying group is established. When the original group-purchase activity is initiated, the creator can define the target reward condition parameter. If the commodity order situation can meet the target reward condition, the creator of the extended sub-group can get a preferential discount on commodity order. Another implementation method S 2  of the mobile group-purchase system of the present invention will be described as below. 
         [0036]    (5) Buying Group Establishment Step S 21 : 
         [0037]    When an user intends to initiate group purchase, the user firstly needs to execute a group-purchase application program of the mobile communication device  12  and further input at least one device identification code (such as a phone number) of the second mobile communication device ( 12 ′, 12 ″ . . . ) through the buying group establishment module  121 . Upon completion of the input, the mobile communication device  12  sends an invitation I of the buying group to a plurality of second mobile communication devices ( 12 ′,  12 ″ . . . ) through the group purchase information transmitting module  123 . When the second mobile communication device ( 12 ′,  12 ″ . . . ) executes the group-purchase application program and accepts the invitation, the mobile communication device  12  and each of the second mobile communication device ( 12 ′,  12 ″ . . . ) will report to the group-purchase server  11  so that the group-purchase member record unit  1111  of the group-purchase server  11  can execute member&#39;s identity authentication. After the authentication is completed, the buying group recording module  112  then records the mobile communication device  12  and the invited second mobile communication device ( 12 ′,  12 ″ . . . ) in an original buying group. 
         [0038]    (6) Group-Purchase Information Establishment and Reward Condition Setup Step S 22 : 
         [0039]    When the original buying group is established, the creator of the buying group can input a group-purchase information P, a first price of commodity Ps and a target reward condition parameter through the group-purchase information establishment module  122  of the mobile communication device  12 . The target reward condition parameter can be set to be the total number of commodity ordered, the total amount of commodity ordered or the total number of commodity orders, etc., but it is not limited to this. 
         [0040]    (7) Group-Purchase Information Sending Step S 23 : 
         [0041]    When the group-purchase information P is established, it can be displayed on the interface of the group-purchase program application of the mobile communication device  12 . The mobile communication device  12  can establish a plurality of group-purchase information P, then the mobile communication device  12  can select one of the purchase information P and send it to the original buying group through the group-purchase information transmission module  123  so that all the second mobile communication devices ( 12 ′,  12 ″ . . . ) can receive the selected group-purchase information P and then conduct commodity orders through the respective second mobile communication devices ( 12 ′,  12 ″ . . . ). When the mobile communication device  12  transmits the group-purchase information P to the second mobile communication devices ( 12 ′,  12 ″ . . . ), the mobile communication device  12  simultaneously transmits the group-purchase information P to the group-purchase server  11  and stores it in the group-purchase commodity record unit  1112 . 
         [0042]    (8) Extended Sub-Group Establishment and Reward Feedback Step S 24 : 
         [0043]    After anyone of the mobile communication devices in the original buying group executes the buying group extension module, a buying group invitation I is sent out and thus an extended sub-group is established. When group-purchase activity is ended, the reward calculation unit can judge whether the extended sub-group has reached the target reward condition parameter. If the target reward condition parameter is reached, the reward calculation unit will give a discount on the order and calculate a spread profit which is then fed back to the creator of the extended sub-group. In the present embodiment, the spread profit is the difference between the original commodity price and the price having preferentially discounted.
