Problems solved by technology

[0008] Furthermore, compared with single-standby mobile communication terminals, the printed circuit board area of ​​mobile communication terminals with dual-standby capabilities will also increase, and the screens of mid- and low-end mobile communication terminals currently on the market are generally 4.0" and below. This brings challenges in design, especially for manufacturers with strict industrial design requirements.

Abstract

The invention discloses an antenna switching device and a mobile communication terminal. The antenna switching device comprises an antenna port used for being connected to an antenna combination, and at least two kinds of communication unit ports used for being connected to a corresponding radio frequency processing unit in the mobile communication terminal, wherein the antenna port is suitable for being selectively communicated with one of the at least two kinds of communication ports in order that the antenna combination works in a communication mode or a communication mode combination matched with the corresponding radio frequency processing unit. The mobile communication terminal has the beneficial effects of small size, low cost and low design difficulty.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an antenna switching device and a mobile communication terminal. Background technique [0002] With the vigorous development of various Internet applications, the existing third-generation (3G, 3Generation) communication network can no longer meet the growing needs of people. Wireless communication systems are increasingly showing the development trend of mobility, broadband and Internet. Under this situation, LTE (Long Term Evolution, 3GPP long-term evolution project), as the fourth generation (4G, 4Generation) communication technology, has become the future The direction of network evolution. [0003] The LTE network is based on the Internet Protocol (IP, Internet Protocol) architecture, and can only provide voice over IP (VoIP, Voice over IP) services based on the packet domain (PS, Packet Switched). and service control capability, therefore, the IP Multimedia Subsystem (IM...
