The following describes several main interaction processes of the APP of the mobile device side and the proxy server to further explain the present invention:
1) registration procedure
Referring to fig. 6, the whole registration process is as follows:
1. after the app of the mobile device end is started, a Register message is sent to a proxy server (namely, a proxy server), the URL of the sip is the address of pbx server, for example, the From field is sip: user name @ pbx server IP address;
2. after receiving the Register message, the proxy server analyzes the address of the pbx server, then converts the contact field of the Register message into a push server IP and forwards the IP to the pbx server;
3. after receiving the Register message, the PBX server replies 401 response according to the authentication information;
4. the proxy server forwards the received response to the APP;
5. the APP sends a Register message carrying authentication information to the proxy server again;
6. the proxy server forwards the register message carrying the authentication information to pbx;
7. pbx the server replies 200 OK if the verification is passed after the authentication information is authenticated in advance, and replies 401 authentication information if the verification is failed;
8. after receiving the 200 OK response, the proxy service stores the registration information (including a user name, an IP address, a contact address, a validity period and the like) of the account number in a registration state database, and then forwards the 200 OK response message to the APP;
9. after receiving the 200 OK response, the APP displays that the registration is successful;
10. pbx after the server saves the registration information, it updates the client registration database, and whether the device number, user name and password of the matched APP exist:
(1) the device number of the APP exists in a client registration database, and when the device number of the APP is matched with the user name, if the registration is successful, the processing is not carried out; if the registration fails, removing the equipment number of the APP in the client registration database, and logging out the APP account number from the PBX server;
(2) the device number of the APP exists in a client registration database, and when the device number of the APP does not match with the user name, the old user name is logged out of the PBX server, and the old user name is removed from the client registration database; meanwhile, adding a new user name into a client registration database, and registering the new user name to a PBX server;
(3) when the device number of the APP is not in the client registration database, a user name and password request message is sent to the APP of the mobile device terminal; after receiving the user name and the password, storing the received user name and the password in a client registration database, and sending registration information to a PBX server;
11. after receiving the username and password request message, the APP replies a 200 ok response, and the body of the response carries the username and password.
Note: 1. at present, only when the device number of the APP is not matched with the user name and the device number is matched with the user name but the registration is failed, the client registration information in the client registration database is removed, and the keyword is the device number of the APP instead of the user name when the client registration information is removed; 2. when a plurality of apps register the same account, only one piece of client registration information is reserved, and the registration information contains a plurality of equipment numbers.
2) Logoff procedure
Referring to fig. 7, the whole logout process is as follows:
1. when the APP normally exits, an Unregister message is sent to a proxy server;
2. when receiving the Unregister message, the proxy server does not forward the Unregister message to the pbx server for authentication operation, but directly replies an APP response, and the specific flow is consistent with the standard flow;
3. the proxy server continues to send a Register message to the pbx server periodically for keep-alive operations.
Note: (1) when the proxy server receives the Unregister message, only the register database of the account is operated, but the database of the client is not operated, and the proxy server continues to maintain the register message; (2) for abnormal exit of the APP, another heartbeat mechanism (such as an option message) needs to be added; (3) when the app is restored to the factory setting or the account is emptied and the server is not notified, the proxy server client still registers to the pbx server, and when a call is received, the app is still waken up, but the call is kept until the caller hangs up because the app cannot be successfully registered.
3) Obtaining user name and password
Referring to fig. 8, the whole acquisition process is as follows:
1. the proxy server sends a Message to the APP, and the body carries an encryption mode and a temporary key;
2. after the APP of the mobile equipment terminal analyzes the body of the message, an encryption mode and a temporary key are obtained, and a user name and a password in the body are subjected to type encryption transmission;
3. after the proxy server receives the 200 response, the decryption body obtains the user name and the password, then adds the user name and the password to the proxy server, and sends the registration to the pbx server.
4) Online call flow
The online calling flow is consistent with the standard SIP calling flow, and no extension is made; the proxy server uses the route-record field to inform pbx the server to look up the forwarding routing information; when invite is forwarded, the contact field cannot be replaced.
5) Off-line called flow
Referring to fig. 9, the whole offline called process is as follows:
1. since the contact field of the register message sent by the app is modified when the Proxy server registers the account of the app with the pbx server, the pbx server sends an invite message to the Proxy server when the account of the app is called;
2. after receiving the invite message, the Proxy server queries a registration state database to acquire registration information of the account, directly replies 100 and 180 responses if the registration information is not displayed online, stores call information inside, and then informs the push server to forward and inform a third-party platform to wake up app for registration; wherein, the proxy server replies 180 to the PBX server, which aims to keep the current incoming call and further go down to process the off-line pushing and registering affairs;
3. after receiving the registration success, the Proxy server forwards the invite message which is kept before to the app, and then the flow is consistent with the normal call flow.
Based on the same inventive concept, the application also provides a device corresponding to the method in the first embodiment, which is detailed in the second embodiment.
Example two
