Abstract:
1. A method, comprising: a) receiving at a network node from a core network entity a plurality of data packets scheduled for transmission during a scheduling period and synchronization information for a plurality of service bearers; b) determining whether there is an overflow condition based on the received synchronization information and transmission resources reserved for the plurality of service bearers for the scheduling period in a single-frequency network; c) upon determining that the overflow condition is present, selecting among the plurality of service bearers at least one service bearer based on a bearer selection function, wherein the bearer selection function results in selecting the service bearer with a highest value or a lowest value of a ratio of two quantities each with a specific value for each of the plurality of service bearers, and wherein the bearer selection function does not directly compute any ratio; and d) dropping a data packet from the selected at least one service bearer, wherein the two quantities are an amount of data assigned to the selected service bearer, and an amount of data guaranteed for the selected service bearer by its guaranteed bit rate for the scheduling period respectively, and each of the plurality of service bearers is a broadcast service bearer, and wherein the bearer selection function involves computing for each of the broadcast service bearers a bearer selection value Pi, wherein Pi=D
