Abstract
The invention relates to the call display processing method of an IP telephone access equipment. The method comprises the following steps: (a): call display message including standard call display message frame is sent down by a server sidewise IP telephone access equipment; (b): after receiving the call display message sent down by the server, the IP telephone access equipment analyzes out the modulation adopted by the call display message from call display message frame; (c): the IP telephone access equipment sends down the call display message frame to a telephone at the time sequence stipulated by the call display standard of the modulation. The invention facilitates the IP telephone access equipment to support not only the telephone of FSK modulation but also the telephone of DTMF modulation, improves the compatibility of the IP telephone access equipment with the telephone and meets the standards of the call display in different countries.
Description
Technical field
The present invention relates to the caller identification processing method of multimedia communication system, refer in particular to the caller identification processing method of voip communication system.
Background technology
So-called IP phone is meant main with a kind of novel telephone system of IP Packet Based Network as transmission medium.IP telephony system mainly is made up of end system and server, the end system of IP phone can come together to finish the access of IP phone by multiple multi-media communication control protocol and server, wherein H.248 agreement, MGCP agreement, Session Initiation Protocol, H.323 agreement all is very important multi-media communication control protocol.
The caller identification business that realizes for IP telephone access equipment is meant: IP telephone access equipment (or being the IP phone end system) carries out certain processing to the caller identification Indication message that server sends, send the incoming call shows signal by analog line to the caller identification receiving equipment, the caller identification receiving equipment demonstrates corresponding caller id information.
The caller identification signal that transmits on the analog line has two kinds at present, and a kind of is the frequency shift keying fsk signal, and a kind of is the dual tone multi-frequency dtmf signal.But a series of relevant criterion of above-mentioned various protocols all do not relate to the caller identification business that how to realize the dtmf signal form, more do not relate to the support that how to realize FSK, two kinds of standard caller identifications of DTMF business.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of caller identification processing method of voip communication system, makes IP telephone access equipment not only support the FSK standard but also supports the phone of DTMF standard.
In order to solve the problems of the technologies described above, the invention provides a kind of caller identification processing method of IP telephone access equipment, may further comprise the steps:
(a) server side issues caller identification message to IP telephone access equipment, comprises the caller identification message frame of standard;
(b) after IP telephone access equipment is received the caller identification message that server side issues, analyze the standard that it adopts from wherein caller identification message frame;
(c) IP telephone access equipment issues this caller identification message frame in the sequential of the caller identification standard code of this standard to phone.
Further, can adopt the caller id information frame of which kind of standard in the described step (a) by the means given server side of configuration in the caller identification message that issues, this standard is determined according to the standard of using in location or the net.
The content that IP telephone access equipment of the present invention issues caller identification standard message frame according to server side draws the method for using which kind of standard and realizes support to FSK, two kinds of standard caller identifications of DTMF business.Make IP telephone access equipment realize support to the caller identification business of FSK, two kinds of standards of DTMF, promptly not only can support the FSK standard but also support the phone of DTMF standard, improve the compatibility of IP telephone access equipment dialogue machine, satisfied the standard of the caller identification of country variant.
Description of drawings
Fig. 1 is a networking diagram of the present invention.
Fig. 2 is the flow chart of the caller identification processing method of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail again:
Networking of the present invention comprises the IP telephone access equipment that links to each other by IP network and coupled phone as shown in Figure 1.IP telephone access equipment should support to issue the caller identification message of two kinds of standards for supporting dissimilar phones.
The specific implementation process of the inventive method may further comprise the steps as shown in Figure 2 at least:
Step 110, server side issues caller identification message to IP telephone access equipment (also can be described as end side), the form of message is a text formatting, parameters such as caller id information frame information are arranged, the form of this parameter is the caller identification message frame of standard, concrete message format definition can be the FSK standard referring to the definition during H.248.23 Andisp wraps, and also can be the DTMF standard;
Can adopt the caller id information frame of which kind of standard in advance by the means given server side of configuration.Usually, only use a kind of standard to get final product in an area (as country) or a net, server side can dispose the standard of use in view of the above.
After step 120, IP telephone access equipment are received the caller identification message that server side issues, analyze the standard of its use according to caller identification message frame wherein;
Step 130, IP telephone access equipment issues this caller identification message frame in the sequential of the caller identification standard code of this standard to phone.
Caller identification flow process with two application examples specifies the treatment step of this method below, protocol of I P telephone access equipment is an example to adopt H.248, but the present invention can be applicable to MGCP agreement, Session Initiation Protocol and multiple multi-media communication control protocol such as agreement H.323 equally.
In first example, the standard of the caller identification message frame indication that server side issues is the FSK standard.The caller identification Indication message that server side issues is as follows:
Signals{andisp/data{db＝802001083035313831363135020A3931393535353030303007084A6F686E20446F65D5}}
The andisp/data signal is that indication IP telephone access equipment issues caller identification message, and this message comprises following information:
IP telephone access equipment is received this message, draws needs according to this message frame and uses the FSK standard, and the sequential of stipulating by this standard issues this caller identification message frame to the phone side.
In second example, the standard of the caller identification message frame indication that server side issues is the DTMF standard.It is as follows that server side issues the caller identification Indication message:
Signals{andisp/data{db＝A12345678C}}
The andisp/data signal is that indication IP telephone access equipment issues caller identification message, and this message comprises following information:
IP telephone access equipment is received this message, draws needs according to this message frame and uses the DTMF standard, and the sequential of stipulating by this standard issues the caller identification message frame to the phone side.
The description of the application by above-mentioned caller identification processing method, use the caller identification processing method among the present invention, make IP telephone access equipment not only support the FSK standard but also support the phone of DTMF standard, improve the compatibility of IP telephone access equipment dialogue machine, satisfied the standard of the caller identification of country variant.
