Abstract
The invention relates to a packet domain real-time service on-line maintaining method, comprising the following steps: a registration timing device is started when a terminal is powered on, and a real-time service client side monitors a voice call conservation process of a circuit domain of a terminal; the registration timing device is cycle-started according to the preset time interval, when timing is ended, whether the terminal is in a conversation process is judged, if yes, timing is continued; when the conversation process is detected to be completed, whether the conversation process time is out of limit is judged, if yes, the registration flow from the terminal to a real-time service platform is initiated, so as to be convenient to reset the real-time on-line state of a PPP (Point-to-Point Protocol) link, and the registration timing device is reset and is started according to the preset time interval continuously. The invention also relates to a terminal with packet domain real-time service and circuit domain voice service simultaneously. In the invention, under the condition that long-time circuit domain voice call ending causes the PPP link to be disassembled, the registration flow is actively initiated at a terminal side in an event-triggering manner, so as to reactivate the PPP link and ensure the real-time on-line state of the real-time service.
Description
Technical field
The present invention relates to mobile communication technology, particularly relate to the online keeping method of a kind of packet domain real time business and system.
Background technology
Internet protocol (Internet Protocol is called for short IP) is the technical foundation of internet network layer protocol, and its structure is simple, easy heterogeneous networks interconnection, extension of network is strong, and may operate in any one data link high-rise, the scope of application is extremely extensive.IP agreement occupies dominant position in data service code, becomes the core of miscellaneous service.Therefore each large normal structure all determines the evolution scheme of AIPN (All IP Network), 3GPP wireless side introduces HSPA (High Speed Packet Access), HSPA+ (High Speed Packet Access+) LTE (Long Term Evolution), 3GPP2 completes standard and the commercialization of EV-DO for a long time.
Along with the development of IP, IP-based wireless access network also will get more and more.But IP operation and general asynchronous transfer mode (Asynchronous Transfer Mode, be called for short ATM) business unlike, when IP operation is as ordinary call business, as VoIP, VT etc., Always Online" must be kept, namely ppp link is set to always on, user terminal could as called, otherwise ICQ is less than user terminal, loses as called chance.
To consider that the decline of circuit domain and packet domain become main flow will be an incremental process, and both will deposit in one section of long time.Operator inevitably runs into and uses multiple network simultaneously, and heterogeneous networks carries the situation of different business.From current present situation, circuit domain main voice-over class business, and packet domain progressively transfers from carrying (Best-Effort is called for short BE) class business of doing one's best the speech carrying real-time class to, and as Qchat business, VT etc.
Real-time class business is carried under packet network, network is needed to maintain the function such business being kept to real-time online (always on), existing solution is that AAA issues PPP Idletime parameter, packet data serving node (Packet Data Serving Node, be called for short PDSN) periodically issue echo request message to terminal according to this parameter, if terminal does not respond this request (namely sending echo response message responsively) at the appointed time, ppp link will be removed by PDSN.
But the situation of reality is, terminal use is user off the net more than, use the voice as CDMA 1x network simultaneously, the Qchat of CDMA 1x EVDO RevA network, video telephone (Video Telephony, be called for short VT) etc. business, if a user connects the phone territory voice call of CDMA 1x for a long time, because terminal can cause when using circuit domain business can not maintaining online heartbeat message by the real time business that issues of normal response core net, therefore the echo request that network issues may be missed, and then ppp link may be caused to remove, like this will cause the business of real-time online can not real-time online.
Summary of the invention
The object of the invention is to propose the online keeping method of a kind of packet domain real time business and terminal, can solve and cause terminal as the problem of callee's paging failure of packet domain real-time online business because of long-time circuit domain voice call.

Open the registration timing device in the real time business client arranged in described terminal when starting up of terminal, the voice telephone calls process of described real time business client to the circuit domain of described terminal is monitored;
Described registration timing device is according to prefixed time interval loop start, and when arriving prefixed time interval, described real time business client judges whether described terminal is in described voice telephone calls process, if be in described voice telephone calls process, then described registration timing device continues timing;
When described real time business client detect described voice telephone calls process complete time, judge that whether described registration timing device is overtime, if overtime, then initiate the register flow path of described terminal to real time business platform, to reset the real-time online state of peer-peer protocol ppp link, and reset described registration timing device, and continue according to prefixed time interval loop start.
For achieving the above object, the invention provides a kind of terminal simultaneously opening packet domain real time business and circuit domain speech business, comprising:
Circuit domain voice call module, for providing the function of circuit domain voice call;
Packet domain real time business module, for providing packet domain real time business function;
Real time business Registering modules, for initiating the register flow path to real time business platform;
Real time business client, comprises registration timing device, for opening described registration timing device when described starting up of terminal, and monitors the voice telephone calls process of the circuit domain of described terminal; Described registration timing device is according to prefixed time interval loop start, and judge whether described terminal is in voice telephone calls process when arriving prefixed time interval, if be in described voice telephone calls process, then described registration timing device continues timing; When described real time business client detect described voice telephone calls process complete time, judge that whether described registration timing device is overtime, if overtime, initiate the register flow path of described terminal to real time business platform, to reset the real-time online state of peer-peer protocol ppp link, and reset described registration timing device, and continue according to prefixed time interval loop start.
Based on technique scheme, the present invention when long-time circuit domain voice call is complete cause ppp link to be removed, at the mode initiation register flow path initiatively that end side triggers with event, reactivate ppp link, and then ensure the real-time online state of real time business.
