Abstract: While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel ( 202 ). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel ( 204 ), and the UE is placed in idle mode ( 206 ). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.

Abstract: A wireless device ( 105 ) for scheduling a forward access channel measurement occasion (FMO) includes a transmitter ( 202 ) to transmit radio signals required to perform random access channel (RACH) transmission (RACHing) and report the results of cell measurements. A receiver receives radio signals required to acquire information blocks, serving cell selection criteria, and measurement rule parameters, and to measure at least one of inter-frequency and inter-radio access technology (inter-RAT) neighbor cells. A scheduling module ( 212, 214, 216 ) schedules FMO frames for neighbor cell measurement in order to prioritize FMO frames that collide with a position of an information block or that collide with RACHing.

EN EL MODO DE OPERACION EN CANAL LA BANDA DE PASO DE UN FILTRO (145, 144) SE ESTRECHA CON RELACION A LA BANDA DE PASO DEL FILTRO EN EL MODO DE COMUNICACION. SEGUN OTRO ASPECTO DEL CIRCUITO, UN OSCILADOR LOCAL (112, 142, 157) SE ENGANCHA EN FASE SELECTIVAMENTE CON UN RELOJ INTERNO (137), DURANTE LA EXPLORACION DE CANAL, Y CON LA SEÑAL ENTRANTE, DURANTE EL MODO DE OPERACION EN COMUNICACION.

Abstract: A multi-mode wireless communication device (100) includes two separate receivers (130, 132) associated with two different radio access technologies and a multi-mode channel selection circuit (174). The first receiver (130) and second receiver (132) operate simultaneously to receive a first signal (150) on a first channel and a second signal (152) on a second channel respectively. The multi-mode channel selection circuit (174) then obtains from the first signal first cell selection information (950) and from the second signal second cell selection information (952). Then the multi-mode channel selection circuit (174) selects a suitable channel to camp on based on the first and second cell selection information (950, 952). The present invention also includes a method with the steps of receiving the first and second signals with simultaneously operating receivers (130, 132), obtaining first and second cell selection information (950, 952), and selecting a suitable channel to camp on based on the first and second cell selection information (950, 952).

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

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.
