Abstract
A radio access network comprises a base station controller and a plurality of radio base stations. The radio base stations connect to the base station controller in a daisy chain configuration via a shared communication link. At least one radio base station in the chain includes a priority queue for scheduling packets to be transmitted via the shared communication link to an adjacent radio base station. The priority queue schedules packets for transmission over the shared communication link based on the location of the terminating radio base station for each packet so that packets traversing more hops are given priority over packets traversing fewer hops.
Claims48
A radio access network comprising:
- a base station controller;
- a plurality of radio base stations station connected to the base station controller in a daisy chain configuration via a shared communication link, wherein the base station controller and each radio base station comprises a node in a chain;
- at least one node in the chain including a first priority queue for scheduling packets to be transmitted via the shared communication link to an adjacent node in the chain;
- and
- wherein the first priority queue schedules packets for transmission over the shared communication link based on a location of a terminating node for each packet.
A radio base station for a radio access network, said radio base station comprising one node in a series of connected nodes on a shared communication link, said radio base station comprising:
- an input for receiving packets;
- a first priority queue for scheduling packets to be transmitted via the shared communication link to an adjacent node;
- and
- wherein the first priority queue schedules the packets for transmission over the shared communication link based on a location of the terminating node for each packet.
A method implemented in a radio access network comprising a plurality of radio base stations connected in a daisy chain configuration with a base station controller, said method comprising:
- receiving packets at a radio base station in a chain of radio base stations to be transmitted to other radio base stations in the chain of radio base stations;
- determining the location of the terminating radio base station in said chain of radio base stations for each of the packets to be transmitted
- determining a priority level of the packets based on the location of the terminating radio base stations for the packets;
- scheduling the packets for transmission according to the priority levels of the packets.
