Abstract

The invention provides an IMS (IP Multimedia Subsystem) facsimile implementation method based on a XML (Extensive Makeup Language) tunnel, which is used for packaging and transmitting the facsimile by using the characteristics of the XML tunnel. The method comprises the following steps of: firstly, executing XML tunnel transmission: when performing the facsimile service, transmitting complete tunnel data at once through the XML tunnel, or caching to receive complete data firstly, and then printing; and then, performing inverse decoding: directly encoding the facsimile into text or picture form in a method of transmitting codes, and directly printing while receiving the facsimile. The facsimile is transmitted in the IMS tunnel, so that failure in the middle of the transmission process caused by network jitter is avoided, and the stability of the facsimile is improved greatly; and in the XML tunnel, the facsimile information is packaged into text or picture information for transmission, and thus the dependence on the terminal decoding and a facsimile apparatus is reduced.

Description

The fax implementation method of IMS based under XML tunnel

Technical field

The present invention relates to the fax implementation method of a kind of IMS based under XML tunnel, belong to telecommunications network communication technical field.

Background technology

Along with the deployment of IMS network, facsimile service stability in use in IP network has been subject to challenge, and especially T38 faxes, and success rate is not very high, and how this improves fax stability for user, has become urgent problem.

Summary of the invention

The present invention is directed to current IMS network not enough to the stability of fax, the fax implementation method of a kind of IMS based under XML tunnel is provided, be intended to improve fax mode, greatly improve fax stability and performance.

Object of the present invention is achieved through the following technical solutions:

The fax implementation method of IMS based under XML tunnel, feature is: utilize the characteristic in XML tunnel to fax encapsulation transmission, comprise the following steps:

First, XML tunnel transmission: during facsimile service, make the disposable entire data that sends of tunneling data by XML tunnel, or first buffer memory is accepted partial data and printed;

Then anti-decoding: by sending coding method, directly facsimile coding is become to the form of text or picture, while receiving faxes, directly print.

Further, the fax implementation method of above-mentioned IMS based under XML tunnel, anti-decoding: for the file of scanning or the text of opening, encapsulate, a text of opening needs to transmit, by following form coding, the content of data for needing to transmit

<FAX-txt>

<data/>

</FAX-txt?>

For the data of facsimile machine or first decoding, then encode;

According to standard packaging, transmit information: for the data that encode, be packaged into facsimile format and send, data is for pressing coded data or facsimile data

<?FAX?>

<data/>

</?FAX?>

Same for decoding: the fax obtaining according to the decoding of xml reference format is text or picture if, according to the processing of text or picture, facsimile coding is pressed facsimile coding decoding if.

The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:

Under IMS tunnel, transmit fax, avoid because dying on the vine of causing of network jitter improved the stability of fax greatly; In XML tunnel, facsimile message packing is encapsulated as to text or pictorial information transmission, reduced opposite end decoding and the dependence to facsimile machine.Also facsimile message directly can be packed and decoded by opposite end, realize traditional fax mode.Propose XML tunnel fax, improved greatly the stability of fax; Propose the anti-decoding of fax, greatly saved the cost of fax.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

Fig. 1: the anti-decoding process schematic diagram of fax.

Embodiment

The fax implementation method of IMS of the present invention based under XML tunnel, utilize the characteristic in XML tunnel to fax encapsulation transmission, its step: first, XML tunnel transmission: during facsimile service, for facsimile data, reduce the impact of network jitter on fax, by XML tunnel, make the disposable entire data that sends of tunneling data, or first buffer memory accepts partial data and print, use XML tunnel to guarantee the stable of data; Then, anti-decoding: adopt to send coding techniques, directly facsimile coding is become to the form of text or picture, while receiving faxes, directly print, can be because of not having facsimile machine or facsimile machine unstable and cause acceptance termination.

Facsimile method based on XML tunnel, has enriched the function that XML tunnel is used.Specific implementation is as shown in Figure 1: 1. anti-decoding (coding): encapsulate for the file scanning or the text of opening.Such as a text of opening needs to transmit, by following form coding, the content of data for needing to transmit

<FAX-txt>

<data/>

</FAX-txt?>

Data for facsimile machine also can first be decoded, then according to above-mentioned coding, have reduced like this recipient when decoding because network jitter and terminating reception.

2. according to standard packaging, transmit information: for the data that encode, be packaged into facsimile format and send, data is for pressing 1. coded data or facsimile data (data of traditional facsimile machine collection are not decoded)

<?FAX?>

<data/>

</?FAX?>

For decoding, be also the same: the fax obtaining according to the decoding of xml reference format is text or picture if, according to the processing of text or picture, facsimile coding is pressed facsimile coding decoding if.

Under IMS tunnel, transmit fax, avoid because dying on the vine of causing of network jitter improved the stability of fax greatly.In XML tunnel, facsimile message packing is encapsulated as to text or pictorial information transmission, reduced opposite end decoding and the dependence to facsimile machine.Also facsimile message directly can be packed and decoded by opposite end, realize traditional fax mode.Propose XML tunnel fax, improved greatly the stability of fax.Propose the anti-decoding of fax, greatly saved the cost of fax.

It is to be understood that: the above is only the preferred embodiment of the present invention; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.

Claims

The fax implementation method of 1.IMS based under XML tunnel, is characterized in that: utilize the characteristic in XML tunnel to fax encapsulation transmission, comprise the following steps:

First, anti-decoding: by sending coding method, directly facsimile coding is become to the form of text or picture;

Then XML tunnel transmission: during facsimile service, make the disposable entire data that sends of tunneling data by XML tunnel; While receiving faxes, directly print or first buffer memory is accepted partial data and printed;

Wherein, described anti-decoding: for the file of scanning or the text of opening, encapsulate, by following form coding, the content of data for needing to transmit

<FAX-txt>

<data/>

</FAX-txt?>

For the data of facsimile machine or first decoding, then encode;

According to standard packaging, transmit information: for the data that encode, be packaged into facsimile format and send, data or facsimile data that data obtains for anti-decoding

<?FAX?>

<data/>

</?FAX?>

Same for decoding: the fax obtaining according to the decoding of xml reference format is text or picture if, according to the processing of text or picture, facsimile coding is pressed facsimile coding decoding if.
