摘要:
L'invention concerne un système de radiodiffusion d'émission relayée dans lequel deux signaux (103 et 106) destinés à une radiodiffuison simultanée sont transmis à partir d'un site de source (100) à des sites éloignés (200) discrets les uns par rapport aux autres. Les deux signaux sont traités séparément au niveau des sites éloignés, y compris l'introduction d'une temporisation appropriée (305 et 312), avant d'être combinés pour être radiodiffusés conjointement avec d'autres sites éloignés. On peut aussi prévoir un ou plusieurs sites de contrôle (400) afin de contrôler la cohérence de la réception dans le système et afin de produire des informations de mesure de fonctionnement et permettre la commande automatique de divers paramètres de systèmes d'émission relayée, y compris la temporisation.

The invention relates to a method for processing an original global stream, outputting a modified global stream, said original global stream being emitted by a head-end and intended for a plurality of broadcast sites, and including at least one physical layer tunnel encapsulating a transport stream. According to the invention, such a method implements the following steps: receiving (11) said original global stream; for at least one physical layer tunnel of said original global stream, referred to as the original tunnel: extracting (12) the transport stream encapsulated in said original tunnel, referred to as the original transport stream; obtaining (13) a modified transport stream; time-shifting (14) said original global stream; aligning (15) said modified transport stream with said original global stream obtained after time-shifting; and replacing (16) said original transport stream with said modified transport stream in the original tunnel.

Operation of a network node in a mobile communication system that serves a User Equipment (UE) includes ascertaining whether the network node is operating in a broadcast-only mode. If so, then broadcast channel information is transmitted on a physical multicast/broadcast channel. Otherwise, the broadcast channel information is transmitted on a physical broadcast channel. To inform the UE of where to find the broadcast channel information, the network node transmits an indicator to the UE, wherein the indicator indicates whether the broadcast channel information is conveyed via the physical broadcast channel or the physical multicast/broadcast channel. The indicator can be included within signals that are also used to enable a UE's cell search procedure.

This invention discloses a control method of a single-frequency network and a control entity of a single-frequency network. The control method of the single-frequency network provided by this invention comprises: obtaining the service request information sent by a user terminal; changing the single-frequency network according to the service request information. The control entity of the single-frequency network provided by this invention comprises: an obtaining unit, used for obtaining the service request information sent by a user terminal; a controlling unit, used for changing the single-frequency network according to the service request information. This invention realizes the dynamic control of a single-frequency network by changing the single-frequency network according to the service request information sent by a user terminal. Consequently, the service provider can dynamically change a single-frequency network according to the requirement of users and implement the optimization configuration of wireless network resources.
摘要:
An enhanced bypass mode simulcast radio communication system (200) includes a plurality of transmit/receive (T/R) sites (2101, 2102, 2103) configured to participate in a simulcasting communication session responsive to a control point system (201). A site controller (211) is responsive to determination of a timing malfunction at a first one of the T/R sites. In response, the site controller is configured to automatically terminate participation of the malfunctioning T/R site in the simulcasting communication session and perform further actions to cause the malfunctioning site to transition to a multisite mode of operation involving a network switching center (202). The simulcast system automatically adjusts its site timing to compensate for the loss of the T/R site in bypass.
