There is disclosed a security device for use in a wireless network comprising a group of base stations that communicate with numerous mobile stations. The security device prevents an unprovisioned one of the mobile stations from accessing an Internet protocol (IP) data network through the wireless network. The security device comprises a first controller for receiving from the unprovisioned mobile station an IP data packet comprising an IP packet header and an IP packet payload. The first controller replaces the IP packet header with a replacement IP packet header containing an IP address of a selected provisioning server of the wireless network. The first controller selects the provisioning server by selecting the IP address in the replacement IP packet header according to a load spreading algorithm.

A software upgrade server that remotely links a software upgrade file as a DLL and transmits the DLL to a mobile station via a wireless network. The mobile station comprises a memory for storing the software file and a controller that communicates with the software upgrade server. The controller receives a message from the software upgrade server indicating a software file is available for upgrading. The controller determines an available space in the memory where the available software file may be installed and transmits to the software upgrade server a target address at the start of the available memory space. The server uses the target address to link a plurality of object files into a DLL and transmits the DLL to the mobile station.

A software upgrade server capable of upgrading a wireless mobile station via a wireless network. The software upgrade server comprises: 1) a database for storing a plurality of software upgrade files as a plurality of object files and a plurality of image files suitable for use in the wireless mobile station; and 2) an upgrade controller associated with the database for communicating with the mobile station via the wireless network. The upgrade controller receives from the mobile station a select message selecting one of the software upgrade files and a target address associated with an original image file in a memory of the mobile station. The upgrade controller links selected object files to form a dynamically linked library (DLL) file based on the target address. The upgrade controller retrieves from the database a copy of the original image file and generates a delta file corresponding to differences between the original image file and the DLL file and transmits the delta file to the wireless mobile station.

An access point for communicating with mobile stations in an integrated wireless network. The access point comprises a first transceiver for communicating with selected mobile stations within a short distance of the access point and an input/output interface that couples the access point to an external mobile station via a communication bus. The externally coupled mobile station communicates with a first base station in a wireless public network. The access point further comprises a data processor that communicates with the externally coupled mobile station via the input/output interface and interconnection circuitry that transfers data traffic between the first transceiver and the data processor. The access point enables the selected mobile stations to communicate with the first base station via the externally coupled mobile station.

Apparatus and method for adapting WI-FI access point to wireless backhaul link of a wireless network

A proxy at the interface between a wireless communications system and a packet network intercepts all traffic between the wireless communications systems and the packet network and re-formats the intercepted traffic according to an optimal maximum transmission unit size between the interception point and the final destination, excluding the wireless link from computation of the optimal maximum transmission unit size. Typically this will result in packets from the wireless communications system being aggregated into a larger maximum transmission unit size, while packets from the packet network are fragmented into a smaller maximum transmission unit size. Congestion at intermediate nodes within the packet network is reduced, while end-to-end bandwidth utilization and latency at the final destination are improved.

The service provisioning system comprises: 1) a database for storing a service provisioning file comprising a mobile station service provisioning program in interpreted byte-code format; and 2) a provisioning controller coupled to the database that receives a notification indicating that a first mobile station is unprovisioned and, in response thereto retrieves the service provisioning file from the database and transmits the service provisioning file to the first mobile station. Receipt of the service provisioning file causes the mobile station to execute the mobile station service provisioning program in the service provisioning file. There also is disclosed a mobile station capable of being provisioned from a wireless network by an over-the-air (OTA) service provisioning process. The mobile station comprises 1) an RF transceiver that receives and demodulates forward channel messages from the wireless network and modulates and transmits reverse channel messages to the wireless network; and 2) a main controller that receives the demodulated forward channel messages from the RF transceiver and extracts therefrom a service provisioning file containing a mobile station service provisioning program in interpreted byte-code format. The main controller, in response to receipt of the service provisioning file, interprets and executes the interpreted byte-code application program.

System and method for secure provisioning of a mobile station from a provisioning server using encryption

A mobile station location server determines the mobile station's location through various location techniques or by receiving the location information from the mobile station over an encrypted channel. The server stores the location in memory that may be access by authorized client access devices. A requesting client access device transmits a request to the server over the Internet. The server authenticates the request to verify that the client access device is authorized to receive the location information. If the client access device is authorized, the server can then transmit the information in either an encrypted or decrypted form to the device.
