BACKGROUND With the rapid development of mobile communication technologies and cloud computing technologies, people can exchange information with the network anytime and anywhere through a large number of terminals of different types and platforms (for example, portable devices, mobile phones, or PDAs). These greatly facilitate the user's requirements for the storage, query, retrieval, access and entertainment of information. This not only provides people with fast and convenient means of communication, but also stimulates telecom operators to develop a variety of new services to improve their service levels and market competitiveness. However, due to the current different terminal equipment platforms, uneven computing power, and different screen sizes, this poses a problem for operators to provide the same service for different terminals or to provide differentiated services for the same terminal.

FIG. 6 is a flowchart of a similar terminal adaptation according to Embodiment 2 of the present invention. As shown in FIG. 6, the service adaptation process is as follows: Step S601: The user agent 42 generates a GUID for the terminal and sends it to the service server. Step S602: The service server 43 receives the GUID and retrieves the key value in the database. If the key corresponding to the GUID is found, go to step S606, otherwise go to step S603; step S603: the service server 43 requests to acquire the terminal capability parameter; step S604: the user agent 42 sends the terminal capability parameter information to the service server 43; step S605: The terminal capability information server writes the terminal capability parameter information into the terminal capability parameter database.

If yes, go to step S707, otherwise go to the next step; Step S702: The user agent 42 determines whether the terminal capability is changed? If yes, go to step S707, otherwise go to step S703; step S703: user agent 42 generates a GUID for the terminal and sends it to the service server 43; step S704: the service server 43 receives the GUID and is in the terminal capability parameter database 44 Retrieving the key value; Step S705: determining whether the key corresponding to the GUID can be found in the terminal capability parameter database? If yes, proceed to the next step, otherwise proceed to step S708; Step S706: the service server 43 finds the service according to the value corresponding to the key. Adapting, the process ends; Step S707: The user agent 42 collects the terminal capability parameter information, and sends it to the service server 43 together with the GUID, and proceeds to step S710; Step S708: The service server 43 requests to acquire the terminal capability parameter, and proceeds to the next step; Step S709: The user agent 42 sends the terminal capability parameter information to the service server 43. Step S710: The terminal capability information server 44 writes the terminal capability parameter information into the terminal capability parameter database 44, and proceeds to step S706. Embodiment 4 This embodiment is used to explain in detail the construction method of the GUID and the Key. Specifically, when the terminal capability parameter database server 44 receives the GUID and the terminal parameter information from the service server 43, the mapping relationship between the GUID and the Key can be constructed as follows: (1) Same parameters for the same terminal. Map a terminal of the same type to a Key through a function, as shown in Figure 8. For example, the corresponding key can be generated by using IMEI TAC (model approval number) and/or terminal user-agent parameters, correspondingly, in the database. Only one terminal device parameter information needs to be saved;

(2) Different parameters of the same kind of terminal. In this case, a record needs to be maintained for each terminal, and the corresponding Key and GUID constitute a mapping, as shown in Figure 9;

(3) The same parameters of different terminals. In this case, a record needs to be maintained for each terminal, and the corresponding Key and GUID constitute a mapping, as shown in Figure 10;

(4) Different parameters of different terminals. In this case, a record needs to be maintained for each terminal. The corresponding Key and GUID constitute a mapping, as shown in Figure 9. In summary, the embodiment of the present invention provides a terminal capability adaptation method and apparatus based on a (key, value) key-value pair, which can effectively reduce the transmission overhead of the network, because the user terminal capability change speed is normally used. Slower (software and hardware upgrades, etc.), and the GUID is much smaller than the terminal capability parameter information, which is beneficial to improve the utilization of network resources, and avoids that the terminal capability parameter information needs to be transmitted between the terminal and the server in each service request; On the one hand, the (key, value) storage mode can improve the efficiency of querying the terminal capability parameters, and is convenient for programming. At the same time, the storage mode of writing once and multiple readings saves server resources.
