In Fig. 3, "First" in step 302, the user can use the mobile communication device 202 and connect to the WML server 206 through the WAP gateway 204 to subscribe to at least one channel, such as a weather channel and a stock channel. Of course, the ψAP viewer must be installed in the mobile communication device 202 in advance before the user can browse the W ML webpage of the WML server 206 on the channel subscription directly on the WAP browser. Then, enter step 304. After the user subscribes, 'WML Temple Server 206 will generate a subscription form according to the channel items to which the user subscribes' and this subscription form uses an extensible markup language. XML) format. It should be noted that the entrance address of the subscription can be set in advance, or can be set by the user. After the user's subscription is completed, the WML server 206 will automatically add parameters such as the user ID (User ID) and the phone number (PhoneNo) corresponding to the mobile communication device 202 to help the WML server determine the user ’s profile in 2006. Use permissions. For example, the entry address ^: '1 http: / / www. Okwap. Com / info / subscribe. Asp ", the actual address is " http: / / www · okwap. Com / info / subscribe. Asp?

UserID = 0387437834 & PhoneNo = 13805165662n. Then, in step 306, the WML server 206 encodes the subscription form as a subscription structure document type definition (SS DTD) to facilitate transmission. Next, in step 307, the WML server 206 will send the SS DTD to the SQL server 208 and the mobile communication device 202 at the same time. Since the content of the SS DTD follows the standard XML 1.0 agreement, it describes the channels to which users subscribe and the items under each channel. In addition, the format of the SS DTD is expressed by compressed binary, which is a format of WAP binary XML (WAP binary XML, WBXML). Therefore, the present invention will use the wbxml protocol to transmit the ss DTD to the SQL server 20 8 and the mobile communication device 202 to improve the transmission efficiency and compatibility. Next, in step 308, the SQL server 208 receives the SS DTD and stores the ss DTD. Of course, the user's name and phone number are also transmitted to the SQL server 208 along with the SSD DTD for storage and backup. In addition, the mobile communication device 202 also receives the SS DTD, and decodes and restores the SS DTD to the original subscription list to display and inform the user. It can be seen that software that can be used to decode the SS DTD as a subscription form must be installed in the mobile communication device 202, and can be used for classification, organization, and management to achieve the function of users subscribing to multiple types of information simultaneously. Then, in step 31, the SQL server 20 8 periodically determines whether the information of the channels subscribed by the user in the WML server 20 6 has been updated. If yes, go to step 312; otherwise, end this method. In step 312, the SQL server 208 generates an update letter

Among them, the update information includes which channels the user has previously subscribed to have been updated and notifies the user how to know the updated information of the channel. Next, it proceeds to step 31 4 ', the push server 21 receives the update information and pushes the update information to the mobile communication device 202. It should be noted that the update information will be transmitted from the push server 210 to the mobile communication device 202 in the form of a service load (SL) short message service (SMS). This is a connectionless push broadcast technology, and SL SMS has a un i form resource location (URL) address of the updated information of the channel, which allows users to link to the Internet to update the subscribed channel Information. Then, in step 316, the mobile communication device 202 receives the update information. Then, in step 3 18, the user can use the WAP browser in the mobile communication device 202 and connect to the URL address in the update information through the WAP gateway 204. The updated information of the channel is downloaded, and the old information of the channel of the mobile communication device 202 is updated, so that the user can get the latest information in real time. This method ends here. It should be noted that in the character set of the SS DTD, the use of the con-tent-type block in the SS DTD is consistent with the relevant rules in the WML agreement, but the meta-information block is not supported. In the SS element, it is described as <! ELEMENT ss (generalchn wood, stockchn ?, eatherchn?) ≫ ° The SS element contains three sub-elements, namely generalchn, stockchn, and weatherchn.
