    Abstract: A main-remote radio base station system includes plural remote radio units. Fiber costs are significantly reduced using a single optical fiber that communicates information between the main unit and the remote units connected in a series configuration. Information from the main unit is sent over a first fiber path to the remote units so that the same information is transmitted over the radio interface by the remote units at substantially the same time. The main unit receives the same information from each of the remote units over a second fiber path at substantially the same time. Delay associated with each remote unit is compensated for by advancing a time when information is sent to each remote unit. A data distribution approach over a single fiber avoids the expense of separate fiber couplings between the main unit and each RRU. That approach also avoids the expense of WDM technology including lasers, filters, and OADMs as well as the logistical overhead needed to keep track of different wavelength dependent devices.

    Abstract: A method of ordering the delivery of a unicast media stream to a second client terminal coupled to an IP Multimedia Subsystem network is described. The method comprises first sending a unicast media order from a first client terminal to an application server of said IP Multimedia Subsystem network. A Session Initiation Protocol INVITE message is then sent from the application server to said second client in response to receipt of said order, the INVITE message containing a media Universal Resource Locator identifying a media source. The Universal Resource Locator is used to exchange Real Time Streaming Protocol signalling between the second client terminal and the application server to initiate and control delivery of the media.

    Abstract: A method and arrangement in a multimedia gateway (300) connected to a multimedia service network (304), for providing access to multimedia services for communication devices (302) connected to a private network. The multimedia gateway may include a device database (316), a communication unit (312) and a logic unit (314). A service identity is associated with the multimedia gateway and is valid in the multimedia service network. When a session request is received, a session is established on behalf of at least one device in the private network using said service identity and capabilities of said at least one device. Thereby, no individual service identity is necessary for the selected device (s). If the session request is a session invitation of an incoming request, said at least one device is selected based on capability requirements for the session.
