Abstract:
1. A radio communications system comprising: a first radio base station node including a first carrier interface and a first bus interface wherein the first carrier interface is configured to communicate carrier data between the first radio base station node and a mobile switching center over a carrier bus according to a carrier protocol, and wherein the bus interface is configured to commumcate over a radio base station bus according to a radio base station protocol that is different from the carrier protocol; and a second radio base station node including a second bus interface wherein the second bus interface is configured to communicate over the radio base station bus according to the radio base station protocol wherein the carrier data includes user payload data for the second radio base station node, wherein the user payload data for the second radio base station node is coupled between the radio base station bus and the carrier bus through the first carrier interface and the first bus interface of the first radio base station node so that the user payload data for the second radio base station node is communicated as bus data over the radio base station bus wherein the carrier data includes user payload data for the first radio base station node and wherein the user payload data for the first radio base station node is not communicated over the radio base station bus.
