Moreover, the connection device numbers connected to - i are PDA1, Mobile 1 and PC1, respectively, representing a number of assistants with a wireless communication capability and a mobile phone, and a personal computer connected by a conventional Internet connection. The wireless communication device registration unit 2 0 1 4 is for inputting a wireless communication device data, and an internet address, which is a network address assigned by the DHCp to the wireless communication device data. If its Internet address falls in the subdomain section 1 4 〇. 1 3 〇, 4 1. *, 1 4 0 . 1 3 0 . 4 2 β * , U 0 . 1 3 0. 43· * Or 140· 13 0· 44. *, the wireless communication device data and the network address of the network are added to the application server record 2 〇丨 3. If the internet address falls in the second subdomain data, the wireless communication device data and the internet address are transmitted to the wireless communication device registration unit 2丨丨3, and the wireless communication device registration unit 2丨丨3 to register. The database 2 1 1 1 is similar to the database 2 〇 1 1 for storing the application server record 2 1 1 2 for recording the application sub-domain area & ' j managed by each application server and connecting to each application The connected device number of the server. > the line communication device registration unit 2丨丨3, for processing the data transferred by the wireless communication device, the main unit 2 〇1 4, registering the wireless communication device with the 7-knife-compatible communication device to the appropriate On the application server, and record this registration with 鬌I to the application server record 2丨丨2.

Invention Description (11) 1 1 2 0 0 contains a shared memory area 2 0 2 1 , a connected database 2 〇 2 2, a shared memory management list tl 2 0 2 3, a shared memory compensation Unit 2 〇 2 4 and an application server register unit 2 0 2 5 . ~ The Drought Memory Area 2 0 2 1 is used to store all interactive information between connected devices. This information can be a variable or an interactive transaction log. Each application server will have its own memory area, and the interactive information of all connected devices in the entire system environment will be stored in this shared memory area. The connection database 2〇22 is used to record a connection time and a disconnection time corresponding to a connected device. If there is no regular action to clear the expired message, the shared memory area 202 1 will eventually continue to back up the interactive message between the connected devices due to insufficient space, resulting in the disconnected connection of the connected device. After the recovery, the information lost during the disconnection period cannot be taken, resulting in inconsistent data between the connected devices. The shared memory management unit 2〇23 is used to provide a method for deleting expired messages to ensure consistent data between connected devices. The shared memory management unit 2 0 2 3 will calculate all application servers in a certain area according to the connection database 2 0 2 2, without any connected device disconnection and ensuring that the shared memory space is maintained at the minimum capacity. The maximum network transmission delay time in the communication interaction is taken as a consideration factor for periodically deleting the expired data in the shared memory area 2, so the shared memory management unit 2 〇2 3 will be reduced by the current system time point. The maximum network transmission delay time is used as a new starting point for the backup data, and the backup data in the shared memory area 2 0 2 1 is cleared before the new starting point. As the system time continues, all the application servers arrive. The new system time point is shared memory area 2 〇 2丨 also

When there is a - link device • nt 1 at Τ 1 The day-to-day point is disconnected from the application server. Suppose c 11 ent 1 is the first disconnection in the system. At this time, the application server will be disconnected from the server (^1, 16111:1 at 1'1). The information is recorded to the connection database 2 0 2 2 and marked with the index value as Dindexi, because the mark is the current index is the smallest index value in the case of disconnection, so the server will set the mark Dlndexl as the earliest disconnection time, As the starting point of the shared memory backup data, the shared memory area will start to damage the data lost during the C 1 ient 1 line from the earliest disconnection time; then, when another customer = C 1 1 ent 2 is disconnected from the system at time T 2, as in the case of servo = The device will record the information of Client 2's disconnection at T2 and use the index value to indicate that σ has become Dindex2'. Then C 1 ient 2 resumes the connection at T 3 time. At this time, the server will restore Client 2 to T3. When the line is marked with the index value as Clndexl 'and the shared memory compensation unit 2〇24 is used to compensate the ci ient 2 for the poor material to Cl ient 2; then at the T4 time Cl ient 3 is disconnected 'The server then puts the C1 The information recorded by ient 3 at the time of T4 disconnection is shown as Dlndex3 'this time because there is still a smaller value than the index value of Dindex3 in the system', indicating that there is still a client that has not resumed connection, so the earliest disconnection time The mark still points to Dindexl, wait until c 1 ient 1 is at T5
