摘要： A method and apparatus method of filtering packet data for an anonymous user device in a packet data network communication system includes a first step of defining a special context information element containing special context information. A next step includes sending the special context information element in an activate packet data protocol (PDP) context request to a network to initiate a call from an anonymous user device. A next step includes receiving the activate PDP context request and the special context information element. A next step includes configuring the data packets so that only the special context is allowed. A next step includes assigning an interim identity and interim IP address to the user device. A next step includes mapping the data packets of the configuring step to the interim IP address of the user device. A next step includes defining permissible routing identities per the special context. A next step includes routing the data packets between only those permissible routing identities from the defining step.

摘要： A cellular network protocol that maintains the reliability of assisted GPS based positioning is taught. An Integrity Monitor (IM) informs mobile stations, their users, or networks of measurement quality and it warns them of failing and failed GPS satellites by isolating them from the effects of these failures. Whenever an unhealthy satellite is detected, its corresponding assistance data will be excluded for delivery or for position determination. In other words, there are two specific aspects to the Integrity Monitor (IM). For DGPS users, it predicts the reliability or quality of the DGPS corrections. For all users, it isolates the mobile position calculation from the effects of GPS satellite failures. The UDRE parameter, nominally output by a reference DGPS receiver, is used to communicate the DGPS quality information, and DGPS corrections are simply excluded for failed satellites. For autonomous GPS users, a special integrity message is required and defined to communicate the satellite failure status information.

摘要： Satellite positioning system enabled mobile receivers (310) and cellular communication network base stations (330) synchronized with satellite positioning system clocks and method therefore. In a network-assisted embodiment, a variable propagation delay for transmission of an assistance message (232) from the base station to the mobile receiver is determined for correcting the handset clock (318). In others embodiments, local clock drift of mobile receivers (310) and/or base stations (330) are determined by a ratio of local and satellite time differences, based on sequential time snapshots, for use in correcting the local clocks.

摘要： An assisted global positioning satellite (Assisted GPS) system has a GPS reference network node (260) that collects GPS satellite broadcast messages and prepares separate GPS assistance messages to be modulated by a base transceiver station (BTS) (202) on a cellular carrier signal (201) and sent to single or multiple handset (204). In a first preferred embodiment, instead of the handset (204) receiving standard ephemeris and clock correction data elements in a GPS assistance message, a compressed GPS assistance message containing XYZ information contains a GPS satellite's coordinate position modified according to the satellite clock correction. In a second preferred embodiment, there is a first type of compressed GPS assistance message containing subframe 1, 2, 3 data of a GPS satellite broadcast message and a second type of compressed GPS assistance message containing subframe 4, 5 data of a GPS satellite broadcast message. The compressed GPS assistance messages according to the second preferred embodiment lack redundant or predictable information in order to reduce the size of the compressed GPS assistance message. The first type can be updated at a different rate than the second type in order to reduce the traffic and yet keep the handset (204) up to date.

摘要： GPS assistance message and data issue identifiers for transmission to GPS enabled mobile stations in cellular communications networks and methods therefore. The GPS data issue identifiers indicate whether GPS data, for example corresponding ephemeris and almanac data, stored at the mobile station requires updating. In the exemplary 3rd generation (W-CDMA/UMTS) architecture, the GPS assistance message is a System Information Block (SIB), and the GPS ephemeris data identifier and corresponding satellite identifier is encoded in a value tag included in a Master Information Block (MIB).
