Description

Three mould fixed phone terminals
Technical field
The utility model relates generally to the communications field, especially, relates to a kind of fixed phone terminal with three mould functions.
Background technology
Fixed phone terminal is quite universal at present, and general family and enterprise staff all can be equipped with the fixed line telephone set.Common fixed phone terminal only has a kind of mode of operation, that is, (PSTN) answers and call by PSTN.As everyone knows, PSTN is a kind of circuit-switched network based on analogue technique.In numerous wide area network interconnection techniques, minimum by the PSTN desired communication cost that interconnects, but its data transmission quality and transmission speed are also the poorest, and the network resource utilization of PSTN is also lower simultaneously, the service that is provided mainly is limited to the language service, and content is single.Along with the development of 3G technology, can provide various multimedia services by 3G network, comprise services such as video conference, high speed Internet access, message customization.
From the angle of fixed telephone network operator, undoubtedly, in a very long time from now on, the income that the traditional voice service of PSTN is brought will be the main body that the fixed network operator takes in.But,, also be the task of top priority that operator faces for PSTN seeks new life.Market competition grows in intensity, and meets with immense pressure in price, and emerging IP and the mobile communication service of adding is all wanted to take a share, and the leading position of PSTN is day by day weakening.One big opportunity of PSTN seeking development is exactly by wireless and wired fusion.No matter the user at home, still on the way in unit, he needs and thirsts for unified Internet resources and experience day by day.This new situations need wireless and wired integrated, because the client needs basically is simplicity, ease for use, and some locomotive function on the fixed telephone network.The length that could collect fixed telephone network and mobile network like this has the convenience and the universality of mobile network's business and the reliability of fixed telephone network business, economy and high-quality concurrently.
From the angle of Mobile Network Operator, Mobile Network Operator need expand to mobile service among vast traditional fixed telephone user in order to promote 3G or 2G mobile service.If a kind of fixed phone terminal of supporting wireless network can be provided for this reason, the fixed phone terminal that then only needs to replace the upgrading user just can develop into mobile network user to the fixed telephone network user.
Angle from enterprise, the enterprise customer needs plurality of communication schemes to carry out work usually, comprise by computer internet carry out instant messaging (for example, the voice and video communication of carrying out with QQ, MSN, SKYPE), the voice communication of being undertaken by fixed telephone network with common fixed phone terminal and the communication of being undertaken by wireless network with portable terminal.And every kind of communication pattern (for example all has special-purpose separately terminal, computer, fixed line phone, mobile phone), every kind of special-purpose terminal has input-output equipment (for example, headset, microphone, keyboard or the like) separately, and these terminals UNICOM mutually cause many inconvenience.For instance, if user A in office and external user B, the user C in going on business and user D at home carry out videoconference.Can carry out the free world by MSN and user B and be used to communicate by letter in order to reduce communications cost user A, because the user C mobile phone that can only dial user C on business trips carries out radio communication, user D can dial the Home Telephone of user D at home.Can't carry out videoconference owing to the used communication mode of user B, C and D is different.Support the integrated terminal of above-mentioned multiple communication mode simultaneously then can realize the combination of more flexible communication pattern if can provide a kind of, create bigger benefit.
This shows that telecommunications industry need be treated providing of service with a kind of new angle, is exactly to be the center with network or equipment no longer, but with user or customers as center.No matter the user at home, still on the way in unit, he needs and thirsts for unified Internet resources and experience day by day.This experience should be defined by the user, and be based on immanent, have personalized and ambulant access, and with network and device independent.This new situations need wireless and wired integrated, because the client needs basically is simplicity, ease for use, and some locomotive function on the fixed network.The length that could collect fixed network and mobile network like this has the convenience and the universality of mobile network's business and the reliability of fixed network business, economy and high-quality concurrently.
