Title: Establishing a packet network call between a mobile terminal device and an interworking function
Inventor: LIOY MARCELLO
IPC: H04W76/00
Filed: 2000-06-06
Granted: 2007-05-29
Abstract: A method or system (10) establishes a packet network call over a transmission link extending between a mobile terminal device (12) and an interworking function (18) which comprises a gateway or bridge connection to a network, such as a packet network. The transmission link connects the mobile terminal device (12) to a wireless communication device (14) over a first interface (Rm) and further connects the wireless communication device to the interworking function over a second interface via a wireless link (Um) to a base station (16). The packet network call, once established, comprises a first interface data link formed within a predetermined data link layer across the first interface (Rm) and a second interface data link formed within the predetermined data link layer across the second interface. A flow control is asserted (304) and deasserted (310) on the mobile terminal device (12). During the flow control, the wireless communication device performs a linked control protocol negotiation with the interworking function to establish the second interface data link with the interworking function (18). After the second interface data link is established, and during the flow control, the wireless communication device (14) performs a network control protocol negotiation with the interworking function to establish a second interface network link carried by the second interface data link.

Title: Procede de codage de la parole a basse vitesse sur la base d'un protocole internet
Inventor: LI YINGTAO
IPC: G10L19/18
Filed: 2001-06-12
Granted: 2010-08-24
Abstract: La présente invention concerne un procédé de codage de la parole à basse vitesse sur la base du protocole réseau (IP). Ce procédé consiste à déterminer le paramètre attribut de la parole d'entrée pendant une période (TN) tout en déterminant la meilleure longueur de trame (T) du traitement de parole suivant ; à coder les données parole dans chaque T ; enfin à les sortir après leur mise en paquets par le protocole TCP ou UDP ou le protocole IP. L'utilisation du procédé de codage de compression de la parole à basse vitesse, pour une seule trame, une modification de longueur de trame, une auto-adaptation de bit de intré-trame, s'avère avantageuse pour augmenter l'aptitude au codage de compression et l'efficacité de la transmission. Puisque la partition de datagrammes IP utilise la partition de la trame codant la parole de meilleure longueur de trame sous la forme d'une unité, la qualité de codage et de décodage de la parole source est considérablement améliorée. Un test sonore informel indique si la valeur MOS peut être augmentée 0,1 - 0,2.

Title: Offline code based reloading system
Inventor: ADAMSON RICHARD I C
IPC: G07F7/08
Filed: 2003-05-30
Granted: 2012-10-09
Abstract: An offline code-based reload device and method for adding value to a reconfigurable memory storage means in a portable storage medium. Reload is effected using a reload device not directly connected by telephone or any other communication network to a value supplier. The system uses a "one time use number" ("OTN") generated by a computer program containing an algorithm containing information on the value to be added and a transaction sequence number ("TSN"). Upon presentation of the portable storage medium to the reload device and entry of the OTN into a numeric keypad, the reload device decodes or disassembles the OTN to verify its authenticity, validate that it was created for the specific portable storage medium presented to the reload device and to verify through the TSN that the OTN has not been previously used to add value from the receiving reload device or any other reload device. The reload device further extracts the value from the OTN, adds the value to a selected purse on the portable storage medium and loads a new TSN to the portable storage medium.
