Fig. 4 is a flow chart of realizing voice call or video telephone.Concrete steps are as follows:
Step 41: behind the set-top box electrifying startup, set up TCP between set-top box SIP module and the sip proxy server that pre-sets or UDP is connected; Send REGISTER message to sip proxy server; Sip proxy server is responded 401/407 response, requires authentication; Both sides' authentication; Set-top box SIP module is received 200 OK message, succeeds in registration 401.
Registration process needs periodic refresh, and (about one hour) needs repeating step 41 at set intervals just.
Step 42: set up ACL between Bluetooth terminal and the set-top box Bluetooth protocol module and be connected, during need the experience authentication; Set up CTP between Bluetooth terminal and the set-top box Bluetooth protocol module then and be connected 402.
Step 43: Bluetooth terminal dialing telephone calling begins to set up CTP and calls out control between Bluetooth terminal and the set-top box Bluetooth protocol module.Process comprises: Bluetooth terminal sends the Bluetooth protocol module of the SETUP message 403 of TCS agreement to set-top box, and the latter sends SETUP ACK message 404 to the Bluetooth terminal affirmation then.
Step 44: the interface section converts the Bluetooth cordless telephone protocol signaling to the SIP call control signalling between set-top box Bluetooth protocol module and the SIP module.Detailed process is: set-top box Bluetooth protocol module is received from sending phone exhalation request message (Outgoing call req) after the SETUP message of Bluetooth terminal to the SIP module, comprising called number information 405; After the SIP module is received 180 (ringing) message 407 from sip server, send called ring-back message (Ringing ind) to set-top box Bluetooth protocol module 408; Set-top box Bluetooth protocol module receives that DISCONNECT message 411 backs from Bluetooth terminal send phone on-hook request message (Disconnect req) to SIP module 414.
More than be the situation of Bluetooth terminal as calling party and first on-hook, if Bluetooth terminal is as the callee, and the on-hook of the other side elder generation, then different.Those skilled in the art can utilize the mode of similar step 44 to expand.
Step 45:SIP module is externally initiated SIP phone by INVITE 406 and is called out, and sets up SIP with the callee and calls out control.
After step 46:SIP module was received 200 (OK) message 409 from sip server, closing of the circuit was set up voice link (SCO link) between Bluetooth terminal and the set-top box bluetooth module, and voice link is connected with media processing units; Media processing units with encoded speech data, and sends to the external interface network by network-driven according to SIP phone establishment stage both sides' negotiation parameter and agreement; The callee's of automatic network driving in the future speech data decoding simultaneously, and output to by the set-top box bluetooth module, Bluetooth terminal arrived by the SCO link; The calling and called both sides begin to converse 410.
Step 47: if Visual communications, then behind the closing of the circuit, the application management module is opened local terminal video acquisition function, video data is input to media processing units, media processing units, and is sent on the external interface network by network-driven video data encoding according to SIP phone establishment stage both sides' negotiation parameter and agreement; Callee's video decode of automatic network driving in the future is played on the television set by the TV interface simultaneously;
Step 48: for increasing user's impression, during the conversation, the user can use the distant control function of Bluetooth terminal simultaneously, closes or open, selects TV programme and video to play or close wherein a kind of simultaneously as selecting video, selects voice output to TV or Bluetooth terminal etc.
Step 49: side's on-hook, SIP module, Bluetooth protocol module, Bluetooth terminal are carried out on-hook flow process, end of conversation respectively.For example, after the Bluetooth terminal user on-hook, send DISCONNECT message 411 to set-top box Bluetooth protocol module; The latter returns RELEASE message 412 to Bluetooth terminal, sends on-hook request (Disconnect req) 414 notice SIP modules simultaneously; The SIP module sends 415 on-hooks of BYE message, and it receives that 200 (OK) message, 416 back SIP call out control on-hook flow process and finish; The set-top box Bluetooth terminal receives that RELEASE COMPLETE message 413 back bluetooths calling control on-hook flow processs finish.
Fig. 5 is a flow chart of realizing instant message.
Concrete steps are as follows:
Step 51: behind the set-top box electrifying startup, set up TCP between set-top box SIP module and the sip proxy server that pre-sets or UDP is connected; Send REGISTER message to sip proxy server; Sip proxy server is responded 401/407 response, requires authentication; Both sides' authentication; Set-top box SIP module is received 200 OK message, succeeds in registration 501.Registration process needs periodic refresh, just needs repeating step step 51 every the end time (about one hour).
Step 52: set up ACL between Bluetooth terminal and the set-top box Bluetooth protocol module and be connected, during need the experience authentication; Set up CTP between Bluetooth terminal and the set-top box Bluetooth protocol module then and be connected 502.
Step 53: the presence of Bluetooth terminal real-time update phone book records.Detailed process is: the SIP module is subscribed to the user's online state 503 of (SUBSCRIBE) Bluetooth terminal phone book records; If the user registration success or the state of these records change, notified (NOTIFY) 504 of SIP module meeting; The SIP module is given set-top box Bluetooth protocol module 505 with user status notification, sends to Bluetooth terminal 506 by it again; Bluetooth terminal upgrades the presence of this record, can see intuitively in the time of user's browser phone book.
Step 54: the user selects certain online user's record in the Bluetooth terminal phone directory, sends message 507, is transmitted to SIP module 508 after set-top box Bluetooth protocol module is received, the SIP module sends 509 by MESSAGE message with it;
Step 55:SIP module receives that from sip proxy server this instant message sends successful response 200 (OK) back 510, by Msg ack ind interfac message notification set-top box Bluetooth protocol module 511, send to Bluetooth terminal 512 by it by CL INFO (send msg ack) message, Bluetooth terminal prompting user sends success.
Step 56:SIP module receives instant message, and is transmitted to set-top box Bluetooth protocol module, by its similar above each step of process that sends to Bluetooth terminal, does not illustrate in the drawings.
Fig. 6 is the method figure that realizes distant control function.
Step 61: set up ACL between Bluetooth terminal and the set-top box Bluetooth protocol module and be connected, during need the experience authentication; Set up CTP between Bluetooth terminal and the set-top box Bluetooth protocol module then and be connected 601.The Bluetooth terminal default mode is a telephony mode, uses as phone.
Step 62: by behind " remote control/phone " switch key, Bluetooth terminal enters the remote controller pattern, the button prompting of its MMI interface prompt remote control mode and the method 602 that withdraws from the remote controller pattern;
Step 63: under the remote controller pattern, button on the Bluetooth terminal, key assignments utilize the CL INFO to pass to set-top box, the action 603 of controller top box;
Step 64: the phone incoming call is arranged under this pattern or have message to arrive then to automatically switch to telephony mode; Telephone finished is got back to the remote controller pattern automatically.
In addition; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
