A method and apparatus for providing time-critical band selection in a communication device with dual band or multi-band switching, or, alternatively, for providing dual mode or multi-mode time critical operating ability. The mobile station typically has a transmitter section and a receiver section

A method and apparatus for providing time-critical band selection in a communication device with dual band or multi-band switching, or, alternatively, for providing dual mode or multi-mode time critical operating ability. The mobile station typically has a transmitter section and a receiver section each capable of dual modes of operation, a frequency synthesizer and a controller. The band to band operating method utilizes a frequency command data signal where data derived from the signal is used in a determinable bit stream of data including a frequency data word. The frequency data word is used for defining an operational state of the synthesizer frequency thereby implementing the transceiver's operating channel. At least one bit (or functional bits) from within the bit stream or received signal is used for defining, at least momentarily, the transceiver's "new" operating band (or state). The functional bits can also be used to effectuate other time critical operations of the mobile station, including band to band switching operations (such as MAHO) over two distinct frequency bands; or, one or more can be used to switch or enable control circuits or functions or operations which are time limited or time constrained or which implicate time critical operations of the communication device or apparatus.

The data identifier of the packet switched network indicating the location of the mobile station in the wireless network is determined using the list maintained in the gateway. e outside the range on the faster side and within a range of allowable fluctuation, the following recording sheet is fed at the long sheet feed interval. 5. The sheet feed method of claim 4, further comprising detecting a leading edge of the recording sheet on an upstream side of the secondary sheet feeder, and controlling the recording sheet by secondary sheet feeder according to a leading edge detection signal. 6. The sheet feed method of claim 5, wherein the recording sheet is fed by the primary sheet feeder on the basis of the leading edge detection signal. 7. The sheet feed method of claim 6, wherein the primary sheet feeder is operated on the basis of an operation of the secondary sheet feeder. eferences] 3rdGeneration Partnership Project (3GPP) et al., Universal Mobile Telecommunications Systems (UMTS); TR 23.913 Tubo-Changer Technical Report version, Dec. 13, 1999, pp. 6-18.
