Abstract
The invention relates to a method for realizing a voice message function based on a message wait event in an EPON system. According to the method, when a UA receives SIP information, whether a dialogue exists or not is determined, when the dialogue between the UA and a SIP server does not exist, the SIP information is not discarded in the invention, but a response message is returned to the SIP server, and a status notification of the SIP information is processed further, thus retransmission of the SIP server is avoided; in addition, according to the method of the present invention, when a user terminal is in a non-idle state, a message waiting event identification is stored, and then a further treatment is carried out after the user terminal recovers to an idle state; and a processing method of an interrupted dial tone is simplified further, thereby a problem that a state notification of receiving a voice message can not be processed correctly in the prior art is avoided. The method of the invention has the advantages of simple application mode, low realization cost and wide application range.
Description
Technical field
The present invention relates to EPON network system technical field, the particularly phonetic function technical field in the EPON network system specifically is meant in a kind of EPON system method that realizes the tone information function based on the Messages-Waiting incident.
Background technology

1, according to existing SIP (Session Initiation Protocol, session initiation protocol) Signalling exchange standard, like Fig. 1 and shown in Figure 2; SS (SIP server is given through sending SUBSCRIBLE (subscription) request in the terminal; Sip server), set up a DIALOG (session), SS returns voicemail message through loopback NOTIFY (state notifying); The NOTIFY that follow-up SS sends real-time message information must carry out under the basis that this DIALOG exists; If this DIALOG does not exist, then discard processing is done to this signaling in the terminal, can't realize the tone information function.
2, stutter dial tone (interrupted dial tone), interrupted dialing tone if there is tone information, is then listened in the terminal when user's off-hook after receiving state notifying, and the advice method of interrupted dial tone is comparatively complicated.
3, VMWI (Visual Message Waiting Indication; Visible message is waited for indication): the terminal is after receiving state notifying; If there is tone information; The terminal is done corresponding Message Waiting Indicator through the LCD/LED demonstration, but under busy state, can't be pointed out under idle condition.
In the prior art; Through definition form standard (being VMWI) and behavioral standard (be AMWI, Audio Message Waiting Indication, speech message wait for and indicating); Make most phones in the VOIP field, support the MWI function; That is: simpler efficient Application and Development MWI function enlarges the application of MWI in field of reality, comprises language message etc.The concrete application demand of MWI in the language message can be summarized as follows:
1, form standard:
A. with the phone of LCD: if there is tone information in the voice mail of place, terminal circuit, can show correlated identities (concrete form depends on phone manufacturer) when time on the endpoint registration, there is tone information in prompting, such as showing the envelope pattern.Otherwise do not show relevant sign.
B. with LED lamp phone: if there is tone information in the voice mail of place circuit, phone LED lantern festival is lighted or is glimmered (depending on phone manufacturer) when on the endpoint registration, and there is tone information in prompting.Otherwise phone LED lamp is not done obvious prompting.
C. with LCD and LED lamp phone: VMWI to the application of tone information, with above-mentioned a or b, specifically depend on phone manufacturer.
D. be not with LCD and LED lamp phone: said behavioral standard suggestion voice message information below generally all passing through in this case.
2, behavioral standard:
If there is tone information in the voice mail of place, terminal circuit; When receiver off-book; Hear interrupted dial tone (stutter dial tone) earlier, listen normal dialing tone (dial tone) again, otherwise during receiver off-book by normality handle (such as: if registration user of last time listens dialing tone).
