103 results about "Mobile service provider" patented technology

A mobile service provider (MSP) is a company that offers transmission services to users of wireless devices (smartphones and tablet PCs) through radio frequency (RF) signals rather than through end-to-end wire communication. The major mobile service providers in the United States include Verizon Wireless, Sprint, AT&T and T-Mobile.

Resource allocation method for low-delay and high-reliability services in mobile edge computing

The invention relates to a resource allocation method for a low-delay high-reliability service in mobile edge computing, and belongs to the technical field of mobile communication. According to the method, in a multi-MEC multi-user environment, a user task queue model and an MEC task queue model are described respectively, a theoretical model of mobile service provider network utility maximizationis established with the task queue overflow probability as the constraint, and joint allocation is performed on power resources, bandwidth resources and computing resources. Considering that a constraint condition in the optimization model comprises a limit constraint of a task queue overflow probability; a random optimization problem of time averaging is converted and decomposed into three sub-problems of single-time-slot solving through a Lyapunov optimization theory, including calculation resource allocation of users, bandwidth and power allocation and calculation resource allocation of MEC, and then the three sub-problems are solved respectively. According to the method, the average total income of the MSP is improved while the requirements of users for low time delay and high reliability are met.

The invention relates to an intelligent early warning system and discloses a serious disaster intelligent early warning system based on a mobile information terminal. The serious disaster intelligent early warning system comprises a disaster early warning public information issuing platform and a mobile intelligent terminal. The mobile intelligent terminal is in communication connection with the disaster early warning public information issuing platform through a mobile Internet or a mobile service provider short message gateway. A serious disaster intelligent early warning method based on the mobile information terminal is also disclosed. A disaster information intelligent identification processing system application product is installed on the mobile intelligent terminal. According to a disaster standard information database, when a wireless network is not available, the mobile intelligent terminal may still receive, by means of a SMS manner, disaster early warning information from the disaster early warning public information issuing platform and converts the disaster early warning information into a disaster early warning standard information to be issued. An intelligent terminal user is notified by means of various warning ways such as graphics and text information alarm, voice information alarm, LED state lamp information alarm and the like. As a result, full coverage of disaster information alarm service is achieved.
