Wireless gateway nodes are enabled to support mobile node services, such as content based billing, when a data treatment server is present in the system. Using one of a defined Content Flow Label (CFL), an Application Program Interface (API), and a compression protocol header, content based billing is provided such as by exchanging content and byte count information with the data treatment server.

In order to save radio resources, the present invention provides a method for improving a multi-input multi-output, known as MIMO, procedure for a network of a wireless communications system. The method includes the following steps. Only two parameter values are used in a MIMO operation information element, also called IE, of a MIMO parameter IE, to indicate a user equipment, called UE hereinafter, to start or continue MIMO operation. The UE is indicated to stop the MIMO operation when the MIMO parameter IE is not included in an ACTIVE SET UPDATE, CELL UPDATE CONFIRM, or any reconfiguration message sent to the UE.

Disclosed is a system and method for routing a call to a dual mode wireless device. In accordance with an embodiment of the invention, a network node receives a call. The network node determines that the call is associated with a dual mode wireless device. Once this determination is made, the network node then selects one of a plurality of networks (e.g., cellular network or packet-based network, such as a VoIP network) for use in connecting the call to the dual mode wireless device. The network node then routes the call to the dual mode wireless device via the selected network. During the call, the network node re-routes the call to another network if the network node determines that this other network is now better suited for the call.

A mobile station that includes a smart card associated with a mobile host equipment communicates by means of a protocol that is organized in several layers. These layers include at least a data transport layer of the datagram type that is adapted to transmit integral data packets of a maximum size. The transmission method carries out the step of determining the value of the maximum size of data packets that are capable of being integrally transmitted by the transport layer of the mobile host equipment, and storing that value in the card.

A modulator, and more particularly an HPSK modulator, is disclosed that enables the circuit scale to be reduced and also enables power consumption to be reduced. An HPSK modulator 209 incorporated in a radio communication apparatus or the like is equipped with a spreading code multiplication section 11, a complex arithmetic section 101, a coefficient determination section 51, and raised COS filters 41 and 42. Spreading code multiplication section 11 multiplies transmit data DPDCH1 by a spreading code Cd1. Complex arithmetic section 101 performs complex arithmetic on an output signal output from spreading code multiplication section 11 and a scrambling code Sn, and performs conversion to complex data. Coefficient determination section 51 determines a filter coefficient Ad1n based on a gain factor βd1 that determines transmission power. Raised COS filters 41 and 42 band-limit the complex data using the filter coefficient.

An orthogonal frequency division multiplexing (OFDM) signal transmission apparatus which transmits OFDM signals by using a plurality of transmission antennas includes a subcarrier setting device which sets signals for subcarriers so as to use some of the subcarriers of the OFDM signals as pilot subcarriers to transmit pilot signals and use the remaining subcarriers as data subcarriers to transmit data signals, the subcarrier setting device changing polarities of signals for the pilot subcarriers for each transmission antenna.
