Abstract
A dual-card dual-standby finance POS terminal comprises a main control CPU module, a radio frequency antenna, a business function module and a wireless communication module. The dual-card dual-standby finance POS terminal is characterized in that the dual-card dual-standby finance POS terminal further comprises an SIM card switching module, a first SIM card circuit and a second SIM card circuit; and the SIM card switching module is connected with the wireless communication module, the first SIM card circuit and the second SIM card circuit. Through instantaneous switching of the SIM card switching module, the on-net data transmission and voice business of two SIM cards are realized at the same time, so that the adaption of the POS terminal to a wireless communication network is improved, the stability of the connection between the POS terminal and a service platform is fully ensured, and the popularization and the application of a wireless POS machine are facilitated.
Description
Technical field
The utility model relates to wireless communication field, is specifically related to a kind of double-card dual-standby financial POS terminal.
Background technology
Existing financial POS terminal, most of PSTN cable network that uses is as communication modes, and along with the development of mobile communications network, the financial POS terminal of wireless mode communication (as GSM, CDMA) is widely used.But in actual use, because wireless signal is restricted in indoor penetration capacity, often cause the signal covering of certain particular locality particular operator undesirable, cause the normally quick payment of Connection Service platform realization of radio POS terminal work.
Existing double card list is treated mode, when in the situation of abnormal signal, POS terminal switches to alternate channel, but because the SIM card of alternate channel does not have at holding state, whether the signal that cannot obtain alternate channel is normal, whether switch communication modes successfully exists uncertain, SIM card reactivates and registers in addition, needs just can complete for tens seconds, like this communication of ability Develop Data, re-registering required time terminal traffic cannot normally carry out, poor user experience.
Existing double-card dual-standby scheme is laid 2 communication modules simultaneously, realizes the mode of double-card dual-standby, but such mode cost is high, and design is complicated, and ease for use is poor, and needs 2 cover radio-frequency antennas, and radio-frequency antenna mutually easily disturbs and causes hydraulic performance decline.
Summary of the invention
In order to address the above problem, the utility model provides a kind of double-card dual-standby financial POS terminal (calling in the following text: POS terminal), realizes the communication of double-card dual-standby, to address the above problem by a wireless communication module.
The technical solution adopted in the utility model:
A kind of double-card dual-standby financial POS terminal, comprises master cpu module, radio-frequency antenna, and business function module, wireless communication module, is characterized in that, also comprises SIM card handover module, the first SIM card circuit and the second SIM card circuit; Described SIM card handover module is electrically connected with wireless communication module, the first SIM card circuit, the second SIM card circuit respectively.
By SIM card handover module switching effect, wireless communication module is connected with the first SIM card circuit, the second SIM card circuit respectively; In the time of time much smaller than network chained search time of instantaneous switching, the first SIM card circuit, the each self-corresponding SIM card of the second SIM card circuit can realize simultaneously at net, realize transfer of data and the speech business of 2 SIM cards.
Usefulness of the present utility model is:
By the instantaneous switching of SIM card handover module, 2 SIM cards are realized simultaneously in network data transmission and speech business, improve the adaptability of POS terminal to wireless communication networks, fully ensured the stability of POS terminal Connection Service platform, be conducive to applying of wireless POS machine.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Fig. 2 is embodiment schematic diagram of the present utility model
Embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are further elaborated.
Embodiment 1
As shown in Figure 1, described SIM card handover module is placed on described wireless communication module.Wireless communication module is set up two wireless links with mobile communications network respectively by the first SIM card circuit, the second SIM card circuit, i.e. the first wireless link and the second wireless link, SIM card handover module is by instantaneous switching, make the first wireless link and the second wireless link keep real-time online, in the time that one of them wireless link can not normal communication, POS terminal still can realize wireless telecommunications by another wireless link.
Embodiment 2
As shown in Figure 2, described SIM card handover module is embedded in described wireless communication module.Its operation principle is identical with embodiment 1, does not tire out and states herein.
Obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those skilled in the art carry out equivalence change or change the every other embodiment obtaining according to the utility model, all belong to the scope of the utility model protection.Embodiment, belongs to the scope that the utility model is protected.
