    摘要: A method and apparatus for packet data service discovery are described. A current blacklist comprising entries for wireless networks not providing packet data services (i.e. either not supporting the services or not having a packet data services roaming agreement) is kept in memory of the mobile device based on previous attempts to connect to such networks. Current preferred roaming lists identify whether a given wireless network can be acquired, but do not identify whether a data services roaming agreement exists. At least one of the following advantages is provided: no advance knowledge of data services roaming agreements is required; no mobile device software change is required when the data services roaming agreement changes; mobile device can notify a server of a wireless network status change; significant power savings at the mobile device; and avoid unnecessary network access, which in turn saves network resources and capacity.

    摘要: A semiconductor optical amplifier (SOA) apparatus and related methods are described. The SOA comprises a signal waveguide for guiding an optical signal along a signal path, and further comprises one or more laser cavities having a gain medium lying outside the signal waveguide, the gain medium being sufficiently close to the signal waveguide such that, when the gain medium is pumped with an excitation current, the optical signal traveling down the signal waveguide is amplified by an evanescent coupling effect with the laser cavity. When the gain medium is sufficiently pumped to cause lasing action in the laser cavity, gain-clamped amplification of the optical signal is achieved. Additional features relating to segmented laser cavities, separate pumping of laser cavity segments, DFB/DBR gratings, current profiling to improve ASE noise performance, coupled-cavity lasers, avoidance of injection locking effects, manipulation of gain curve peaks, integration with a tunable vertical cavity coupler, integration with a photodetector, integration with an RZ signal modulator, and other described features may be used with the evanescent coupling case or with an SOA having a laser cavity gain medium that is coextensive with the gain medium of the signal waveguide.

    摘要: Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.
