    Abstract: A method for registering a mobile station (307) in a radiotelephone communication system (300). The mobile station (307) receives system information from a base station (321), including a cell grouping level. The mobile station (307) determines if it is registered with the base station (321). If not, the mobile station (307) registers. The network controller of the radiotelephone communication system (300) automatically registers the mobile stations with all base stations defined by the cell grouping level. The mobile station (307), using the same algorithm, maintains a record of the base stations with which it is automatically registered.

    Abstract: A resynchronization method for use in a communication system, such as a second generation cordless telephone system 800, begins by determining that synchronization has been lost by a receiving unit (830). The receiving unit than mutes any transmit data and generates zero data which is combined with a pattern generated by pattern generator (812). The transmission is then received by handset (830), which detects the pattern generated by pattern generator (812) using pattern detector (850). Pattern detector (850) then generates a pattern detected signal (852) which causes handset (840) to also stop sending data and generate a pattern accompanied by zero data. Base station (830) detects the pattern and again generates another pattern accompanied with zero data which is transmitted to handset (840). Handset (840) after decoding the pattern for the second time begins to resumes the normal transmission of data to base station (830).

    Abstract: A method for re-establishing a communication link that has been lost between a portable unit (406) and a fixed unit or base station (402) provides for a way of quickly re-establishing the lost communication link, on the previously used RF channel. The method is begun by transmitting a link re-establishment code word (900) using MUX 1 after determining that synchronization has been lost (502) for a predetermined period of time (504). This is followed by automatically switching the portable unit (406) from MUX 1 to MUX 3 communication protocol. Followed by re-establishing communication (re-establish synchronization) between the portable (406) and base station (402) in MUX 3 and switching the two communication devices (402 and 406) back to MUX 1 after the communication link has been re-established. The same steps can be followed by base site (402) if it had been the first to detect loss of the communication link.

    Abstract: A low profile antenna comprised of a driven element and a parasitic element spaced above a ground plane. The driven element is connected at one end to the feedpoint of the radio device to which it is attached, the opposite end thereof being free. The parasitic element is connected to the ground plane by its end nearest the feedpoint, the opposite end thereof being free. In the preferred embodiment the parasitic element length and the driven element length are both approximately equal to a quarter wavelength at the operating frequency.
