A radio system comprising a switching and management infrastructure arranged to deliver voice and data between a plurality of communicating parties, and a mobile station. Said radio system comprises a multiplicity of traffic channels, each traffic channel being associated with a unique coding scheme. The switching and management infrastructure is arranged to receive a plurality of paging messages from a plurality of communicating parties, and to combine the paging messages received during a pre-defined time period into a paging frame comprising a multiplicity of address data blocks for identifying the mobile station(s) for which the paging frame comprises a paging message. At least one of the traffic channels of the radio system is dedicated to delivery of downlink paging messages, and associated with a coding scheme that comprises at least one error protection algorithm. The mobile stations are arranged to receive data on said traffic channel, and to extract information addressed to them based on the address blocks of the paging frame.
