Description
Technical Field
The invention belongs to the technical field of digital talkback, and particularly relates to a digital talkback system and a digital talkback method based on a cloud card.
Background
The existing digital intercom system mainly has two modes of realizing intercom based on a wireless private network standard and based on public network data traffic.
The problems of the wireless private network intercom system mainly include: 1) the talkback range is limited, no matter a direct mode without a transfer platform and a private network base station or a transfer and cluster mode with the transfer platform and the private network base station is adopted, the reliable talkback range between the digital interphones is limited, and the talkback service cannot be realized in places which cannot be covered; 2) professional terminals are high in price, and especially private network cluster digital interphones are high in price, so that many common users have to consider the public network digital interphones with lower cost; 3) the infrastructure maintenance cost is high, and because the number of actual interphone users is poor compared with the number of public network mobile phones and the users are used by themselves, under the condition of adopting private network infrastructures such as a transfer platform and a base station, the users have to spend a large amount of cost and expense on maintaining the network.
Obviously, the public network digital interphone has obvious advantages compared with the private network digital interphone, such as: the cost is low, the coverage is wide (as long as there is public network basic station of operator can realize normal talkback), but this type digital intercom also has obvious shortcoming, mainly includes: 1) the digital interphone terminal is complex in setting, such as: different operators in different countries need to set different APNs, and particularly, the simple digital interphone without the display screen and the digital keyboard is more complex without intelligent operating systems such as Android and the like and display screens; 2) the problem of charge renewal in this mode is caused by the problems related to the operator traffic charge and the use charge of the PoC talkback platform, which is completely different from the use mode of the private network digital interphone; 3) once an operator is selected, the problem of poor coverage of the base stations of the individual operators in some places is still encountered; 4) if the public network interphone simultaneously uses 2 SIM cards to select 2 public network operators, the problems of high data flow charge and manual selection of different SIM cards for talkback are involved; 5) when the ordinary PoC public network digital intercom system is adopted, the transaction mode between an intercom system manufacturer and a client becomes more complex, and the two-party transaction (intercom system manufacturer and client) becomes three-party or four-party transaction (intercom system manufacturer, client, public network operator and PoC intercom platform operator), so that the client is daunting on the transaction mode, and the development of the PoC public network intercom industry is hindered to a certain extent.

step S3): if the entity SIM card priority is preset, the entity SIM card is directly used for logging in an operator network, and the cloud card service is not used;
step S4): the PoC digital interphone (3) uses the SIM card to access the operator network and judges whether the PoC digital interphone (3) arrears the flow;
if the flow rate is owed, the flow proceeds to step S8); otherwise, go to step S9);
step S5): the cloud card priority is preset, and no matter whether an entity SIM card exists or not, the locally stored seed SIM card is directly used for logging in a cloud card platform (1);
step S6), the cloud card platform (1) determines the optimal operator that should be selected by the PoC digital interphone (3) according to the received P L MN of each operator and the signal strength information parameter provided by the PoC digital interphone (3), and provides the SIM card mirror image file of the operator to the PoC digital interphone (3);
step S7): the PoC digital interphone (3) uses the cloud card to log in and access the operator network, and judges whether the PoC digital interphone (3) arrears the flow;
if the flow rate is owed, the flow proceeds to step S8); otherwise, go to step S9);
step S8): the PoC digital interphone (3) is in flow arrearage, prompts arrearage information, reminds a user to pay and finishes;
step S9): the PoC digital interphone (3) directly logs in the PoC intercommunication platform (2);
step S10): the PoC digital interphone (3) judges whether the ID of the interphone is in PoC service arrearage or not through the feedback information when the PoC talkback platform (2) logs in;
if the PoC service arrears, prompting arrearage information, reminding the user to pay and ending; otherwise, go to step S11);
step S11): the PoC digital interphone (3) downloads the talkback information of the local machine to the local machine from the PoC talkback platform (2);
step S12): the PoC digital interphone (3) runs the PoC talkback service;
step S13), the PoC digital interphone (3) judges whether the power is low; if yes, ending the PoC service software, and shutting down the power supply; otherwise, returning to step S12) to continue running the PoC talk service.
