A method of controlling the cell re-selection of a mobile station () between cells () of a cellular-based radio access network (). The method comprises the steps of determining when a cell re-selection for the mobile station () is appropriate, determining whether or not the mobile station () is involved in a push to talk service comprising a series of talk bursts, and if the mobile station is involved in a push to talk service, delaying the cell re-selection until such time as a period of silence between talk bursts occurs.

Method for avoiding interruptions of push to talk services

Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. Each transport channel can include an encoder or a decoder coupled to and cooperable with a data puncturer or a data repeater. An information source can produce for each transport channel first configuration information and second configuration information, wherein the first configuration information is indicative of how the associated transport channel is to be configured if a first modulation type is used for a current radio block, and wherein the second configuration information is indicative of how the associated transport channel is to be configured if a second modulation type is used for the current radio block. The physical layer can include a description information source that provides description information from which various configurations of the transport channels can be determined. The description information source provides the description information in the physical layer in response to further information which the description information source receives from a higher layer and which is indicative of a service request initiated by a communication network.

Flexible layer one for radio interface to PLMN

Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. One of the transport channels can be enabled to extract its associated communication information from a radio block while another of the transport channels is maintained disabled. The one transport channel provides the extracted communication information to a decision maker in a higher layer. In response to the extracted communication information, the decision maker decides whether the other transport channel should be enabled, and provides to the physical layer an indication of its decision.
