(2) Voice and limited communication services are supported by the 2G digital technology, which is now active. (3) Voice, low-speed data, and a set of data services are all supported by 3G networks. (4) Mobile broadband in the real sense is enabled by 4G (LTE) technologies, which aim...
digital transmission system,i.e., from 1G to 2G, in the 1990s, which highly improved both the reliability and security of the service. Short message service (SMS) was also added in the global system for mobile communication of 2G. Both time division multiple access and code division multiple...
METHOD AND SYSTEM FOR CONTROLLING ADMISSION IN MOBILE COMMUNICATION NETWORKS, RELATED NETWORK AND COMPUTER PROGRAM PRODUCT THEREFOR A method for controlling admission of calls to a mobile communication network having cells associated to at least one determined threshold level of operation (nUL -max nmax...
As of today, the absence of Mobile IP (MIP) support in most networks implies the need for a reconnection of the service as soon as the access network changes. That is why a new seamless communication concept is required. In the thesis, a new seamless communication concept is proposed. The...
