International Classification:

H04W 4/00

US Classification:

370332

Abstract:

A code division multiple access telecommunications network including an underlay base station in a private premises and a plurality of overlay macro base stations. The underlay base station includes a GPS receiver and a mobile unit receiver. The underlay base station uses its geographic location to obtain information identifying macro base stations within a preselected distance of the underlay base station. It uses the mobile receiver to measure pilot signal strength of the macro base stations. It generates a neighbor list of the identified macro base stations ranked according to pilot signal strength.

International Classification:

H04W 40/00

US Classification:

455446, 4554352, 455444

Abstract:

A method and apparatus use existing datafill information from macrocells to turn-up the cell site. A cell site includes a global position positioning system (GPS) receiver configured to determine a current location of the cell site. A transceiver subsystem in the cell site manages a wireless communication interface, and a controller, coupled to the GPS receiver and the transceiver subsystem. The controller is configured to send the current location of the cell site to a cell site manager, receive cell site identification data for existing macrocells and virtual macrocells from the cell site manager, and selects candidate macrocells based on a selection algorithm until one is validated by the switching center. Datafill information associated with the validated macrocell to create datafill entries for the cell site.

Abstract:

A method for managing an attempted connection between a home base station (HBS) and a device not registered with the HBS is provided. The method includes transferring the connection when the attempted connection can be transferred to a traditional base station. When the attempted connection cannot be transferred to a traditional base station, it is determined whether a portion of the resources of the HBS can be used by the device not registered with the HBS. When a portion of the resources can be used, the portion is used. When a portion of the resources cannot be used, the attempted connection is not completed.

Assignee:

SAMSUNG ELECTRONICS CO., LTD. - Suwon-city

International Classification:

H04L012/66

US Classification:

370352000

Abstract:

A method of terminating a packet data call at a target mobile station (MS) operating in the wireless network. The method comprises the steps of: i) receiving in a PDSN of the wireless network first packet data directed to the target MS; ii) identifying in the first packet data a mobile identification number of the target MS; iii) using the mobile identification number to retrieve an IP address of the target mobile station from a first database of the PDSN; and iv) forwarding the first packet data to the target mobile station using the retrieved IP address. The method further comprises the step of determining from a second database of the PDSN a target PCF unit and a target base station controller with which the target MS is currently in communication.
