Point-to-multipoint transmission of localized data
First Claim
1. A method, comprising:
- allocating a predetermined recurring time period to transmission of localized data specified for users of individual ones of a plurality of sub-areas;
dividing a transmission capacity of a data stream of said predetermined recurring time period among adjacent sub-areas; and
transmitting localized data specified for one of said adjacent sub-areas during said predetermined recurring time period using a divided transmission capacity allocated to one of said adjacent sub-areas,wherein said transmission capacity is divided by defining a predetermined time pattern based on which transmission times for said localized data are allocated to individual ones of said adjacent sub-areas during said predetermined recurring time period, andwherein said predetermined time pattern, based on which transmission times for said localized data are allocated, comprises at least one discontinuous transmission period.

Abstract
The present invention relates to a method, system, network element and computer program product for transmitting a data stream in a point-to-multipoint mode from a source entity to a plurality of users in a predetermined area of a cellular network, said predetermined area comprising a plurality of sub-areas. A predetermined, recurring time period is allocated to transmission of localized data specified for users of individual ones of said plurality of sub-areas, and a transmission capacity of the data stream is divided using said predetermined, recurring time period among adjacent sub-areas. Localized data is then transmitted during the predetermined, recurring time period using a divided transmission capacity allocated to the respective sub-area. Thereby, combination of global and local broadcast or multicast content is enabled in a broadcast system by avoiding overlapping of transmissions with different content at cell edges.
