Combined smart terminal

Abstract

The invention relates to the field of wireless communication, and discloses a combined smart terminal, which can lower the cost of wireless mode updating or transmission of a network of different modes. The smart terminal comprises a sub-phone and a host phone capable of working independently, wherein the sub-phone in the independent state has the most basic voice communication and short message sending / receiving functions; and the host phone can be used independently as a multimedia terminal. The host phone has an internal cavity matched with the sub-phone in size, and the sub-phone can be inserted into the cavity completely. An opening extending to the cavity is processed on the casing of the host phone, and the position of the opening corresponds to that of the speaker of the sub-phone inserted into the cavity, so that the opening can be used for conducting the sound from the speaker of the sub-phone. After being inserted into the cavity of the host phone completely, the sub-phone is connected with the host phone through an electric interface to enable the sub-phone to achieve voice and data communication function as a wireless modem under the control of the host phone.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to intelligent terminal technology. Background technique [0002] A smart terminal, also known as a smart phone, refers to a personal computer that has an independent operating system and can be installed by the user on his own, such as software, games, and other programs provided by third-party service providers, through which the mobile phone is continuously updated. It is a general term for a class of mobile phones that can expand the functions of mobile phones and realize wireless network access through mobile communication networks. Simply put, a smart phone is a mobile phone that can expand the basic functions of the mobile phone by downloading and installing software like a computer. [0003] Broadly speaking, in addition to the call function of a mobile phone, a smartphone also has most of the functions of a Personal Digital Assistant ("PDA"), especially personal infor...

Problems solved by technology

[0004] The current smartphones are all integrated, which means that the various functions of the smartphone are completed on the same independent terminal, and each module is pre-assembled in the same case and shares the same battery. A module that not only does not provide functionality on its own, but the remainder may not work

[0005] The problem with this kind of all-in-one smart phone is that once the user wants to replace the network of a different standard, or the network is upgraded, such as upgrading from Global System for Mobile Communication (GSM) to wideband code division multiple access (Wideband Code Division Multiple Access, referred to as "WCDMA"), the original smart phone can not be used, only to buy a new

In other words, upgrading or changing the network to a network of a different standard will bring high costs to users
