| As the capacity of mobile network transmission enhanced, and the functions of mobile terminal equipments improved, it's possible that anyone can get any service in anyplace at anytime. However, the mobile service is not good at human-computer interaction and the intelligence. The paper proposed a intelligent service mechanism—Context-aware Service Providing Mechanism For Mobile Environment, and designed a mobile guide service which has the characteristic of Web2.0 service and function of context-aware.Compared with many traditional service mechanisms, the paper's scheme can detect the context-aware information through sensor's equipments physically and logically, provide different contents and trigger different services by the strategy of dealing with context-aware. This function of context-aware increases the choosing scope of users' interaction, and improves the system performance of human-computer interaction. What's more, the mechanism adapts the technology of service combination to release the mobile service, which can add the speediness to the service.Based on the mechanism, this paper designed the mobile guide service for travelers, and implemented the travel plan and tracing services, which reflected the context-aware. Referencing the thought of "Everyone Involved" and "Resource Sharing" in Web2.0, the service joined in Blog and SNS, which enriches the users' experience of traveling and promotes the intercommunion in users.The travel plan and tracing services were mainly accomplished to plan the scheme before traveling, trace and remind the travellers during traveling through detecting the information of context-aware such as position, time and so on. The travel plan service was in charge of recommending the travelers with the hot route according to the location information, querying the travel plans and editting them. The tracing service was in charge of tracing the route of travelers, contrast it with the travel plan, and reminding the travelers when error happening. |
