Patent number: 7783322Abstract: A network selection method automatically selects a communication network for a multi-mode mobile communication device, which has operability in two or more communication networks. Plural of digit map strings and a network priority setting are provided and stored in the mobile communication device. An input phone number is compared with all the digit map strings to obtain a match result. A communication network is selected by the mobile communication device among two or more communication networks based on a current network status, the match result, and the network priority setting.Type: GrantFiled: March 4, 2006Date of Patent: August 24, 2010Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Lei Pi, Tsung-Fu Huang, Shu-Ken Lin

Publication number: 20070201681Abstract: A mobile communication device (10) for processing calls of different types includes a call management module (30), a phone book module (40), a call history module (20), and a display module (50). The call management module processes the calls of different types, and generates call histories. Each of the call histories includes a phone number and a call type. The phone book module saves a plurality of phone entries, and each phone entry includes a name, a corresponding phone number, and a corresponding call type. The call history module is connected to the call management module and the phone book module, and saves the call histories. The display module is connected to the call history module, and displays the call histories.Type: ApplicationFiled: August 4, 2006Publication date: August 30, 2007Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: CHING-YUAN CHEN, LEI PI, TSUNG-FU HUANG
