The present invention provides, inter alia, a method of operation of a radio base station in a wireless telecommunications system, in which system information is transmitted on a broadcast control channel. The method comprises the steps of transmitting the broadcast control channel continuously on a first carrier; and also transmitting the broadcast control channel non-continuously and periodically at regular intervals. This prevents or at least minimizes, for example, MBMS data loss when a UE with a single receiver listens to a dedicated MBMS carrier.

The present invention relates to BCCH transmission in a cellular mobile communication system.
As part of HSPA (High speed packet access) evolution, point to multi-point MBMS (multimedia broadcast multicast service) services will be offered on a dedicated downlink carrier in an entire coverage area termed as single frequency network (SFN). This new SFN feature is in addition to the release 6 type of MBMS transmission mechanism, which takes place on the existing carrier.
This section describes various technological aspects and principles of MBMS transmission in UTRAN (UMTS Terrestrial Radio Access Network).
The foregoing and other objects, features and advantages of the invention will be apparent from the following detailed description of preferred embodiments as illustrated in the drawings.
FIG. 1 illustrates part of a wireless telecommunications system according to the present invention;
FIG. 2 illustrates MBMS transmission on a dedicated MBMS carrier;
FIG. 1 illustrates part of a wireless telecommunications network 10 according to the present invention.
The telecommunications network 10 comprises at least one radio base station 20 (alternatively called a network node, node B, or any other name familiar to those skilled in the art). The transmission area 30 of the radio base station 20 is shown as a hexagon surrounding the base station; this transmission area 30 is commonly referred to as a cell. Only one base station and its associated cell are shown for convenience; it will be appreciated that the network 10 will typically comprise many such base stations and cells. Cellular phones 40 (also referred to as user equipments) within the cell 30 receive transmissions from the base station 20 on one or more carriers, and send their own transmissions back to the base station 20. A core network (CN) 50, in communication with the base station 20, controls overall operation of the network 10.
Those skilled in the art will appreciate that many elements of the network 10 have been omitted for clarity. The operation of the base station 20 and the user equipments 40, in particular, is described in further detail below.
