Abstract: A method for using a high order modulation (HoM) mode for communications with a wireless device in a wireless communication network is provided. The method includes receiving downlink channel quality indicator (CQI) information from an uplink transmission of the wireless device and determining a downlink channel quality estimate from the CQI information. When a measurement of the downlink channel quality estimate satisfies the predetermined criteria for a first predetermined number of consecutive uplink transmissions from the wireless device, a downlink transmission mode of the wireless device is switched from a first modulation mode to the HoM mode.

Abstract: A compensated switched capacitor circuit comprises a switched capacitor circuit and a compensation circuit. The compensation circuit generates a reference current that varies under closed loop control to maintain a targeted slew rate for charging a reference capacitor that is determined by the input clock frequency. The switched capacitor circuit's output amplifier is configured such that its output current varies in proportion to the reference current. Thus, by configuring the reference capacitor to track the effective capacitance of the switched capacitor circuit, the settling time of the switched capacitor circuit may be made relatively insensitive to the value of and changes in the effective capacitance over a range of clock frequencies. The compensation circuit may include a clock reconditioning circuit to ensure that the switched capacitor circuit is clocked at a desired duty cycle.

Abstract: A method of charging a subscriber for using GPRS services provided by a mobile communications network. The method comprises including in PDP activation messages sent from a UE used by the subscriber to a GGSN of the network, a flag indicating whether the PDP context is to be used for signalling data or user data. This flag is examined within the network or at a node external to the network, and if the flag indicates that the PDP context is to be used for carrying signalling data, a first charging regime is applied to the subscriber for establishing and using the context, and if the flag indicates that the PDP context is to be used for carrying user data, a different charging regime is applied to the subscriber for establishing and for using the context. The flag may be distributed by the GGSN to other network nodes for inclusion in charging messages.

Abstract: There is disclosed a method of selecting characters from a group of characters assigned to a single key, in particular a key of a telephone dialling keypad. Actuation of a key (8; 16) invokes a cursor controlled display of the characters (2; 18). The cursor is held at a particular position (11) while a key is actuated within a predetermined time interval (t.sub.1 ; 6, 7). The character string corresponding to a particular key actuation is read (18) and is used for the retrieval of the closest matching data entry from memory means (19). If the key is not further actuated within this time interval (t.sub.1), the cursor is moved to a next position (22), provided the selected character string matches any of the data entries of the memory means (20, 21). The retrieved data entry may be used, inter alia, for automatic dialling purposes. The method is applied in a telephone set having memory means containing subscriber data.

Abstract: A general dimensioning method and system for allocating limited transmission resources to various virtual paths defined on top of a physical network. A two-level hierarchical structure is defined with a layer of one or more virtual paths on top of a layer of physical network elements. Traffic demand is specified for each virtual path and the Entropy Rate Function is used as a blocking measure. The loads on the various links are balanced by equalizing blocking probabilities and the optimal allocation of network physical resources is determined.

Abstract: A clock generation circuit operates in a STANDBY mode as well as conventional OFF and ON modes. In STANDBY mode, a small pre-bias current is applied to amplifiers in the clock generation circuit, which bias voltages on internal nodes to very near their operating voltage values. This reduces transient perturbations on signals as the clock generation circuit is returned to ON mode. The smaller transients settle faster, and allow the clock generation circuit to achieve very fast startup times from STANDBY to ON. The very fast startup times allow the clock generation circuit to be placed in STANDBY mode more often, such as when a system must monitor and rapidly respond to activity on an external bus or interface (such as an RF modem).
