Client terminal information encryption processing module, mainly can use SIM key route to automatically configure the key of module generation and carry out key or the encryption of correspondence according to different user.
Preferably, described SIM key route automatically configures module and includes the step of following work process:
Step one: start system;
Step 2: obtain Flash initial address;
Step 3: read 100 bytes;
According to special field " 0xFF " district, step 4: judge whether to be all " F ", judges whether WIFI information write;
Step 5: the ID and the password that parse WIFI are saved in internal memory, judgement according to step 4, if being configured without, then first connection needs user to return step 3 after using bluetooth configuration subscriber equipment end and terminating, if configuring, front 100 bytes can put flag bit, and equipment can arrive the place of agreement and reads WIFI information one by one and attempt connecting and entering next step subsequently;
Step 6: wait that call back function is triggered;
Step 7: attempt connecting local router according to priority;
Step 8: judge that WIFI has connected;If otherwise opening bluetooth to access WIFI hot spot information, utilizing hot information to write Flash by regular length, updating existing WIFI information, returning step 6;If then entering next step;
Step 9: attempt Connection Service device;
Step 10: judge whether server connects, returns step 6 if not, if entering next step;
Step 11: host process creates subprocess.
The most described multichannel SIM note incoming call management module is that remote application end initiates configuration information by internet to server end, server carries out mapping configuration subsequently, configuration information is after corresponding multiple user authentications and parsing, pass to the configuration mapping table of rear class, when configuration information parsing or authentication error, error message will be returned remote application end and subscriber equipment end by server end simultaneously, to reach the purpose synchronized;Specific works method is the note incoming information of operator, through subscriber equipment end bottom layer treatment by the SIM user's mapping block reaching server end in units of SIM user by the way of event message via WIFI, this module can be according to the content of current event message, configuration information in conjunction with self, corresponding process is done for remote application end, it also can keep network to be connected with subscriber equipment end simultaneously, to reach mobile phone short message feedback and the purpose of duty inquiry.
Preferably, described SIM key route automatically configures module and includes SIM user authentication configuration module and SIM user's mapping block;SIM user authentication configuration module be for receive the incoming call and short message of long-range app user forward module is set;SIM user's mapping block is used for depositing the long-range app user account number of reception and actual SIM map information;The step of the SIM user authentication configuration module following work process of employing:
Step 2 11: obtain remote application end configuration information;
Step 2 12: judge whether be one-to-many prompting arrange, if enter step 2 13, if not enter step 2 15;
