Abstract: Apparatus, and an associated method, for negotiating an LLC frame size for a UMA/GAN network. A calculator, embodied at a mobile station, calculates an optimal frame size, i.e., an N201-U value. A negotiation initiator initiates a frame size negotiation with a network entity. The frame size negotiation utilizes the calculated optimal frame size. And, a frame size is allocated responsive to the negotiation. The allocated frame size is used in the formation of user data packets that are constrained to be of sizes that are close to the allocated N201-U value, defined at the LLC layer.

Abstract: Apparatus, and an associated method, for forming a communication connection between a mobile station and a communication network. The communication network is of either of two protocol versions, such as a UMA-compliant network and a GAN-compliant network. A network access identifier is formed at the mobile station of a format that permits its acceptance by the communication network. If a first network access identifier is formed of a format that is incompatible with the protocol version of the communication network, a subsequent network access identifier is formed of the format of the other of the protocol versions. A listing is maintained at the mobile station that identifies the determined protocol version of the communication network.

Abstract: Apparatus, and an associated method, for facilitating transmission of block-formatted data by an EDGE-capable mobile station. When the mobile station is instructed to use an MCS-8 modulation coding scheme, in initial transmission of the data, the mobile station determines the amount of data that is to be transmitted. If only a single RLC block is to be transmitted at MCS-8, MCS-6 is instead utilized. And, padding bytes are added to the MCS-6 data blocks.
