Abstract: An improved system and technique for processing a communications session in a data communications system suitably includes the steps of receiving the communications session at a line interface card, embedding the communications session into an asynchronous transfer mode (ATM) virtual circuit at the line interface card, transporting the virtual circuit from the line interface card to a processor card via a backplane. The processor card suitably extracts the communications session from the virtual circuit, and processes the communications session as appropriate.

Abstract: A power management device (200) and a method for use in a power distribution network (100) receives electrical energy and first determines if the power is a primary or secondary power source. When a secondary power source, the power management device (200) waits in standby mode, but when the power is primary power source the power management device (200) configures itself to route power to another node in the power distribution network (100). Power levels and faults within the network can be monitored and controlled by a central controller. Likewise loads (218, 220) may then be powered on as determined by a central controller to reduce LdI/dt voltage spikes and other undesirable side effects.

Abstract: A method of handling call establishment requests when a MS moves from one Serving Radio Network Controller (SRNC) to another SRNC in a 3G wireless network, such as a UMTS network. If SRNC Relocation is being prepared, an Iu connection request and Paging request received by the SRNC are suspended and stored in a buffer. If the Relocation procedure completes successfully, the messages are discarded. If the Relocation procedure fails or is cancelled, the messages are processed normally. However, if SRNC Relocation has already been triggered, all call establishment messages (except Direct Transfer Messages) received by the SRNC are ignored. Other post Iu connection messages received by the SRNC are processed instead of potentially being ignored.

Abstract: In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40–45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.

The system includes a CDMA 2000 system providing for the dispatch data services. This requires that messages and bearer traffic are processed by radio link protocol.

In addition if there is a low battery level of the speaker, an FCH channel is assigned to the speaker, (30). When the speaker changes, (40), the FCH and DCCH channels for the speaker and listener are switched dynamically, (44–48).
