Patent number: 7613152Abstract: A DBDM (dual band dual mode) terminal is provided for supporting different packet frame modes and a supporting method thereof. This may be provided by mounting a data communication protocol (TCP/UDP/IP/PPP) supporting different communication networks onto a video chip having application of packet data services of the DBDM terminal. It therefore may be possible to remove communication protocols of modem chips for different communication networks applied to a DBDM terminal. Accordingly, consistency of communication protocol may be maintained by using the same communication protocol in different communication networks, and performance of a terminal may also be improved by making application of a packet data service interwork directly with a socket. In addition, by mounting a communication protocol on a video chip, debugging can be easily performed during development.Type: GrantFiled: April 21, 2004Date of Patent: November 3, 2009Assignee: LG Electronics Inc.Inventor: Hyun-Kyung Choi

Patent number: 7313408Abstract: A method and apparatus for enhancing performance of a packet service of a mobile communication terminal is disclosed. When the mobile communication terminal uses a packet service, an RAB set between the mobile communication terminal and a base station is compared to a reference value and the priority level of a packet service task processed in the mobile communication terminal is raised only when the mobile communication terminal is connected to the base station at or above the reference value. When the packet service is terminated, the priority level of the packet service task is returned to an original low priority level. The mobile communication terminal uses a maximum transmission speed for the packet service and when the mobile communication terminal uses a concurrent service requiring both real time service and packet service, packet service performance may be improved without affecting the real time service.Type: GrantFiled: August 19, 2004Date of Patent: December 25, 2007Assignee: LG Electronics Inc.Inventor: Hyun-Kyung Choi
