International Classification:

H04M 1/00
H04Q 7/20

US Classification:

455551, 4555501, 455463, 455461

Abstract:

A system and method for managing multiple mobile stations provisioned for use by a single user with a common mobile identification number (MIN). In an advanced intelligent network, a call control system may receive requests to set one of the multiple mobile stations to an active state. The call control system may also receive requests to set one or more of the multiple mobile stations to an inactive state. The call control system stores the active or inactive indication in a subscriber profile database. When a request is made to register one of the multiple mobile stations for service, the call control system determines if the mobile station is active or inactive. If the mobile station is inactive, it is not permitted to register. If the mobile station is active, it is permitted to register.

Abstract:

A communication system provides communication services to a plurality of communication devices. The communication system includes a transmitting antenna, a transmitter, a first receiving antenna, a second receiving antenna, a second receiver, and a communication interface. The transmitter transmits first wireless signals via the transmitting antenna. The first receiving antenna has a first coverage area of less than forty five degrees. The first receiver receives second wireless signals via the first receiving antenna. The second receiving antenna has a second coverage area of less than forty five degrees, and the second coverage area of the second receiving antenna is within the first coverage area. The second receiver receives third wireless signals via the second receiving antenna. The communication interface provides the communication services between the communication network and the user communication devices.

Abstract:

Methods and systems are provided for dynamic selection by a mobile station of its home agent using its preferred roaming list (PRL). A mobile station maintains a PRL comprising an association between (i) a first set of data identifying a first wireless wide area network (WWAN) and (ii) a first identifier of a first home agent. The mobile station detects a broadcast of the first set of data by the first WWAN. Responsive to detecting the broadcast of the first set of data by the first WWAN, the mobile station connects to the first WWAN. Responsive to connecting to the first WWAN, the mobile station uses the first identifier to register with the first home agent.

US Classification:

Abstract:

A method for selecting a frequency band, from among a plurality of frequency bands controllable by a radio network controller (RNC), to carry a data communication. The method may include obtaining frequency band usage measurements for a plurality of frequency bands, and using the frequency band usage measurements to select a particular frequency band of the plurality of frequency bands to carry the data communication. Frequency band usage measurements may be based on how many idle slots (and/or data channels) are carried through each of the plurality of frequency bands during a measurement time period. A comparison of the frequency band usage measurements can be used to determine which frequency band sent the greatest number of idle slots (or the fewest number of data channels). The method provides for selecting a frequency band best suited (e. g. , has the most available capacity for carrying a data communication) for carrying the data communication.

International Classification:

US Classification:

4551142, 455296, 455302

Abstract:

Elimination of intermodulation interference in a wireless communication system by removing a portion of the spectrum of transmitted signals. According to a received indication of an occurrence of intermodulation interference experienced by a narrowband receiver, mappings are performed between the predetermined narrowband channel frequency on which the narrowband receiver operates and the occupied channel frequencies of at least one broadband transmit signal. Narrowband candidate frequency ranges that linearly combine into frequencies that overlap the predetermined narrowband channel frequency are determined based on the mappings. The narrowband candidate frequency ranges that potentially contribute to the intermodulation interference are then selectively filtered by at least one notch filter until the intermodulation interference is substantially eliminated.

Abstract:

Disclosed herein is a method and apparatus for providing a pilot-beacon on behalf of one or more base stations, such as one or more femtocells. A pilot-beacon transmitter, separate from the base stations, determines the locations of coverage areas of the base stations and then dynamically configures a pilot-beacon radiation pattern to encompass (approximately) the determined coverage areas. That way, a mobile station may detect the pilot beacon and initiate scanning of coverage provided by the base stations. Optimally, the method can be used to provide a pilot beacon for femtocells, thereby avoiding the need for the femtocells to include pilot beacon transmission functions and thus possibly decreasing the cost of the femtocells. The pilot-beacon transmitter or another entity may also be configured to receive and forward GPS signals to the base stations, possibly offsetting GPS timing based on measured delays for communication with the base stations.
