A method is proposed for optimizing the bit rate of multimedia contents accessible by a plurality of user terminals connected to a radiocommunications network cell. The multimedia contents are stored in the form of a plurality of independent chunks on at least one multimedia contents server associated with at least one contents provider. The method includes the following steps, implemented in a device for optimizing the bit rate: receiving one request to obtain a multimedia description file, sent by a user terminal; obtaining a multimedia description file; modifying the multimedia description file on the basis of a piece of information representing a quality of delivery, delivering a modified multimedia description file; and transmitting the modified multimedia description file to the user terminal.

Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of 1 or 1 to one of the start RBG number and the end RBG number of allocated RBG number information (bi) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding 1 to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).

A notified RBG calculating unit (203) that adds a predetermined offset value of 1 or ?1 to one of the start RBG number and the end RBG number of allocated RBG number information (b.sub.i) output by a scheduling unit (201), thereby calculating notified RBG number information (b.sub.i). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding 1 to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (b.sub.i) and the notified total number of RBGs (N.sub.rb) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).

Congestion management for data traffic in a virtual domain identifies a congestion source and sends a message to the source to adjust data traffic rates. The source may be a virtual machine hosted by a physical server with one or more virtual servers incorporated. A congestion manager may identify the source and send the message to the source without affecting other data sources hosted by the physical server or the virtual servers. In some embodiments, information about the congestion source may be encapsulated in a packet payload readable only by the congestion source so only the congestion source receives the instruction to adjust the transmission rate.

A method for communicating content files based on destination priority includes processing a content file to determine a plurality of destination sites to which the content file is to be transmitted, assigning priority levels to the plurality of destination sites, allocating a plurality of bandwidth portions on a communication link to the plurality of destination sites, respectively, based on the priority levels assigned to the plurality of destination sites, and transmitting the content file to the plurality of destination sites using the plurality of bandwidth portions allocated to the plurality of destination on the communication link, respectively.

An audio signal, having first and second regions of frequency spectrum, is coded. Spectral peaks in the first region are encoded by a first coding method. For a segment of the audio signal, a relation between energy of bands in the first and second regions is determined. A relation between the energy of the band in the second region and energy of neighboring bands in the second region is determined. A determination is made whether available bits are sufficient for encoding at least one non-peak segment of the first region and the band in the second region. Responsive to first and second relations fulfilling a respective predetermined criterion and a sufficient number of bits, encoding the band in the second region using a second coding method different from the first coding method, and otherwise, subjecting the band in the second region to BandWidth Extension BWE or noise fill.
