Method and system for distributing multimedia contents through a wireless communications network, particularly a mobile telephony network

Abstract

In a wireless communications network (100) comprising a base station subsystem controlling at least one network cell (BSC1,BTS1,CELL1;BSC2,BTS2, CELL2,BTS3, CELL3,BTS4,CELL4), and in which the base station subsystem communicates with mobile stations (MS1,MS2,MS3,MS5,MS7) in the cell through radio blocks, a method of distributing information contents received in data packets at the base station subsystem to the mobile stations, comprising: obtaining, starting from the data packets, radio blocks (400) to be transmitted through the network cell; labeling the radio blocks with a first radio link identifier, identifying a logic connection between a mobile station and the base station 1.5 subsystem (TF11); communicating the first radio link identifier to a first mobile station (MS1,MS3,MS5) in the network cell; and in case at least one second mobile station (MS2,MS7) in the network cell asks to receive the information contents, communicating thereto the first radio link identifier. The method further includes having the first mobile station and the at least one second mobile station assigned respective second radio link identifiers (MFl1,MFI2,MFI3,MFI5,MFI7), to be included in the radio blocks.

Description

technical field [0001] The present invention relates generally to the field of telecommunications and in particular to wireless mobile communication networks such as mobile telephone networks. In particular, the present invention is concerned with distributing data such as multimedia information content to mobile user terminals (eg mobile phones) over a wireless mobile communication network with respect to data volumes. technical background [0002] The mobile telephone network was originally used to enable voice communication similar to the wired public switched telephone network (PSTN), but between mobile users. [0003] Mobile telephony networks have undergone tremendous expansion, especially in second-generation mobile cellular networks, especially those following the Global System for Mobile Phones (GSM) standard (and its American and Japanese counterparts) after the introduction. [0004] Services provided by these cellular networks other than the usual voice communi...

Problems solved by technology

[0019]Furthermore, the applicant observes that the proposed method exhibits additional and more serious drawbacks: different mobile stations using a given multicast service within a cell have a negative impact on the network devices are indistinguishable, thus addressing information to a specific mobile station is impossible

As another example, this implementation does not allow the mobile station to better modulate some parameters in order to improve the reception quality of the data content, such as the mobile station's timing advance
