Abstract: A data transfer appts. employing a data buse having synchronous and asynchronous modes for communication between a first and second memory units. It determines a need for memory transfer and responsively searches a number of memory segments in the second memory for a valid data record stored in one of the segments. The memory transfer device then communicates the valid data record from the second data unit to the first memory unit in the asynchronous mode when the search finds a valid data record. It communicates an empty data record in the asynchronous mode when the search does not find a valid data record.

Abstract: A cellular phone having a fixed calling capacity limiting use of the phone to emergency situations. Two call sequences are stored in memory permitting telephonic communication with only the two fixed sites associated with the two call sequences. Telephonic communication must be effectuated with a first fixed site, and then terminated, prior to effectuation of telephonic communication with a second fixed site. Telephonic communication with a second fixed site is permitted during a predetermined, limited time period.

Abstract: An emergency call placement method ( 300 ) used in user equipment in idle mode camped on a first cell of a wireless communication network having a first radio access technology includes the steps of requesting ( 316 ) a radio resource control connection using "emergency call" as an establishment request, changing ( 340, 350 ) to a new cell in a different location area or routing area than the first cell, and requesting again ( 316 ) a radio resource control connection using "emergency call" as an establishment request. This method avoids performing a location area update or a routing area update when the user equipment changes to a new cell during an emergency call and thus may speed up placement of the emergency call by several seconds.

Abstract: A receiver (100) has a channel scan mode of operation and a communication mode of operation. In the channel mode of operation, the passband of a filter (145, 144) is narrowed relative to the passband of the filter in the communication mode. According to another aspect of the circuit, a local oscillator (112, 142, 157) is selectively phase locked to an internal clock (137) during channel scanning and locked to the incoming signal during a communication mode operation.

Abstract: A method for a radiotelephone to scan for a higher priority (including home) public land mobile network (PLMN) without searching in all possible RATs and frequencies includes a first step of establishing an inclusive list of all frequencies in all radio access technologies (RATs) in use by the higher priority or home public land mobile network. A next step includes camping the radiotelephone on the higher priority or home PLMN. A next step includes obtaining the inclusive list from the establishing step by the camped radiotelephone from the higher priority or home PLMN. Afterwards, when the radiotelephone roams to a lower priority visited PLMN, it can begin scanning for the home (and higher priority) PLMN using only those frequencies from the inclusive list, thereby saving battery power.
