Embodiment

For making the embodiment of the invention clearer, earlier to type length numerical value (type-length-value, tag-length-value, TLV) form is done simple the introduction: the element of a TLV form is made up of label Tag, length L ength and numerical value Value three parts, wherein, Tag also can be called Type, and Tag is a value code, the type of expression data element; Value is the numerical value of this element reality; The value of Length is the physical length of Value, and wherein, the length of Tag, Length is generally 1-4 byte.

Consult Fig. 1, the embodiment of the invention one provides a kind of transparent data management method, and this method comprises:

Step 101, AS generate the transparent data element that meets the TLV form and store with textual form according to data dictionary.

Following is that example describes with Call Forwarding Unconditional business (CFU), to the data definition of CFU a transparent data, identify the service identification (Service Indication) of this transparent data, be called for short SI and be defined as ats_cfu, suppose that this transparent data has comprised 5 TLV elements, the Tag definition of corresponding TLV element

As shown in table 1, this table 1 is called data dictionary,

The data element sign	The Tag of TLV element	The data element explanation
The data element sign	The Tag of TLV element	The data element explanation	?ForwardToDest	?0x0001	The preceding destination Mobile Station International ISDN Number that changes, TELURI or SIP URI
?ServiceAuth	?0x0002	Whether identifying user has business	?ForwardToDest	?0x0001
?ServiceAuth	?0x0002	Whether identifying user has business	?ServiceAct	?0x0003	Whether identifying user activates this business

?NotifyUser	?0x0004		NotifyServedUser	?0x0005	Whether notify by the called subscriber of preceding commentaries on classics in the time of preceding the commentaries on classics

Table 1

Because transparent data is to store as the part of XML document, store data if use the TLV form, need to consider of the specific (special) requirements of the character of XML for TLV form transparent data, be that the XML form is based on text, can not directly in XML, store for the integer number, otherwise for the reserved character of XML ("＜", "〉", “ ﹠amp; ") identical number, XML will be them as being the reserved character of XML and resolving, and can be them as general numeral, so need convert the value of Tag and Length to the text formatting storage.Can adopt following two kinds of text storage modes, corresponding conversion regime is:

1), the value with Tag and Length converts the ASCII character storage to.

Be specially: earlier the value of Tag and Length being converted to hexadecimal mode represents, and the polishing prefix 0, to guarantee shared byte number, then hexadecimal is converted to ASCII.

For example, the value of Type is 8888, takies byte number and is 2,8888 and be converted to hexadecimal number 0x22B8, is converted to the expression of ASCII character again, is stored as 0x32 0x32 0x62 0x38 in internal memory.Accordingly in internal memory, be stored as 0x30 0x30 0x30 0x31, accounted for 4 bytes for the 0x0001 in the above-mentioned table 1.

For example the value of length is 100 again, and taking byte number is 2, uses hexadecimal representation to be 0x0064, is converted to the expression of ASCII character again, is stored as 0x30 0x30 0x36 0x34 again in the internal memory.

For the value among the value, if character string, just the form that directly character string is converted to ASCII character is deposited.If numerical value, then the form that numerical value is converted to ASCII character is deposited, and the system of numerical value is decided by the definition of different value.The value of Length will be calculated according to the shared length after the value conversion.

From as can be seen above-mentioned, this conversion method is one times of the shared space enlargement of type and length.That is to say that type and length, convert to after the text if take 2 bytes in internal memory as numerical value, storage needs to use 4 bytes in internal memory.But, because type and length represent with value type, rather than represent with character string type, and can clearly identify the length of value subsequently with length, when promptly can obtain element according to value finishes, as XML document, need or not with＜/Tag come marker element to finish, so still saved very big memory space with respect to the XML element.

Illustrate, the value value of supposing a TLV element is 0, and whether notify caller when changeing before this element is wanted to represent, know that according to data dictionary the Tag numerical value of this element is 4, suppose that 4 accounted for two bytes originally in internal memory, in internal memory, account for 4 bytes after converting ASCII to 4, Tag is expressed as 0x30 0x30 0x30 0x34 in internal memory, because the value value is so that 0 Length is 1, Length is expressed as 0x30 0x30 0x30 0x31 in internal memory, the value value is 0 to be expressed as 0x30 in internal memory.This TLV element is expressed as character string in XML document: 000400010.

2), the value with Tag and Length converts the base64 storage to.

The base64 coding is binary number representation a kind of method of readable text exactly, compare with the ASCII coding, the coding method of Base64 is described as follows: ASCII coding is based on 8, base64 is based on 6,26 powers are 64, because this coding has 64 basic code elements, general capital and small letter English alphabet and the numeral selected is as basic code element, so just there have been 62, increase again+and/, be exactly altogether 64 code elements, these 64 texts that code element all is the human-readable in the ASCII character.

Therefore, needing AS to convert the TLV element to the base64 coded format, consult table 2, is the process that the example explanation is transformed into base64 with Man.

Table 2

Step 102, AS send Data Update request (Profile Update Request to HSS, PUR), wherein, this Data Update request is carried the property value of expansion each element to service identification AVP SI and described transparent data by property value to user data AVP User-Data, and the AVP SI of described expansion comprises the transparent data sign and represents that described transparent data is the sign of TLV form.

This step can realize in the following way:

Realize the visit of TLV element by the definition of the SI of expansion on the Sh interface, the SI on the Sh interface is present in two kinds of forms, and the one, directly exist with this AVP of SI, another is that the form with XML element S I exists in this AVP of user-data.---AVP SI and XML element S I---can implement following extended mode for above two SI, SI after the expansion, what comprise that expression need visit is the character string of which transparent data, and can be specific to a TLV element in transparent data of visit.Form after the expansion is as follows:

&&ServiceIndication～～Tag

De ﹠amp wherein; ﹠amp; Be a distinctive mark, represent that the element among the initial thus SI is the TLV form, this is the back compatible for Sh interface, and distinguishes mutually with the transparent data of XML form storage.Wherein～～also be a distinctive mark, as the separator of SI character string and Tag numerical value.Wherein, SI specifies concrete transparent data, and Tag specifies the path of the some TLV elements in the transparent data.

The definition of SI is to adopt character string, under extended format, need carry out certain restriction for the character string that SI uses, and promptly not allow be “ ﹠amp to two characters of SI character string; ﹠amp; ", and can not contain in the middle of the character string "～～".Can certainly adopt the element among other sign expressions SI is the TLV form, perhaps adopts the separator of other signs as SI character string and Tag numerical value, does not influence realization of the present invention.

Wherein, the TLV form is supported nested, following expression two-level nested TLV element;

00010009000400010

Wherein, 0001 is the label Tag1 of father's element; The length L ength1 of 0009 father's element, 000400010 is the numerical value Value1 of father's element; Among the Value1 0004 is the label Tag2 of daughter element; 0001 is the length L ength2 of daughter element, and 0 is the numerical value Value2 of daughter element.

At this moment, the path of representing this daughter element is Tag1/Tag2.The Tag that is the TLV element between multistage needs to use "/" to separate.Therefore in order to visit descendants's element, when adopting step by step route method, the form of expansion SI is under the nested situation of TLV element:

&&ServiceIndication～～Tag1/Tag2..

What indicate to visit is: label is that label is the daughter element of Tag2 in the element of Tag1.Wherein, for restrictive condition of the nested existence of TLV: in same one-level, the data of TLV element and non-TLV element can not exist simultaneously.

In transparent data, allow the TLV element that exists a plurality of Tag values identical, distinguish Tag identical TLV element with label this moment, and illustrate: the label of three TLV elements all is Tag1, and is as follows:

First TLV element: Tag1 Length1 Value1

Second TLV element: Tag1 Length2 Value2

The 3rd TLV element: Tag1 Length3 Value3

Wherein, the path of first TLV element is Tag1[0] or Tag1, being defaulted as first types value of expression for the Tag1 of tape label not is the TLV element of Tag1, the path of second TLV element is Tag1[1], the path of the 3rd TLV element is Tag1[2];

At this moment, the form of expansion SI can be under the nested situation of TLV element:

&&ServiceIndication～～Tag?1[n]/Tag2[m]...

Wherein, Tag1 is the label of father's element, and n represents the order of label in same label of father's element; Tag2 is the label of daughter element, and m represents the order of label in same label of daughter element.

Initially send PUR message for AS in this step,, carry AVP User-Data in this PUR message so that HSS preserves the TLV element that is generated to HSS, in the entrained SI of AVP User-Data, need not comprise～～Tag.The example of continuous above-mentioned Call Forwarding Unconditional business, AVP User-Data is specially:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

<any>

00010014sip://zkh@huawei.com

000200011

000300011

000400010

000500011

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Wherein,＜ServiceIndication〉﹠amp; ﹠amp; Ats_cfu＜/ServiceIndication in De ﹠amp; ﹠amp; That expression is visited subsequently is transparent data ats_cfu; This transparent data comprises the TLV element:

00010014sip://zkh@huawei.com、000200011、000300011、000400010、000500011。

Step 103, HSS preserve each element of the transparent data of this TLV form, and each element that can claim the transparent data of TLV form is the TLV element.

Step 104, when AS need read TLV element in the transparent data, AS sends user data requests (user-data-request to HSS, UDR), this user data requests is carried described transparent data sign, is represented that described transparent data is the path of the sign and the required element that reads of TLV form by AVP SI, for example, the value of AVP SI can Shi ﹠amp; ﹠amp; Ats_cfu～～4, what indicate to visit is that Tag is 4 TLV element among the ats_cfu.

Step 105, HSS Gen Ju ﹠amp; ﹠amp; , what affirmation needed visit is the transparent data of TLV form, with reference to the TLV form, path (Tag is 4) according to this TLV element, search corresponding TLV element 000400010 in transparent data ats_cfu, return UDA message to AS, the value of the AVP User-Data in this message is:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

<any>

000400010

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Above-mentioned steps 104-step 105 does not have sequencing with follow-up step 106-step 107, does not influence realization of the present invention.

Step 106, when AS need write TLV element of transparent data, AS sends the Data Update request (profile-update-request that carries AVP User-Data, PUR), the pairing new element in element path that this Data Update request is carried the AVP SI of expansion and needed to upgrade by AVP User-Data, wherein, the AVP SI of expansion comprises that transparent data sign, expression transparent data are the paths of the sign and the element that needs upgrade of TLV form.

Wherein, the value of the AVP User-Data among the PUR is:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

<any>

000400011

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Expression is that the numerical value of 4 TLV element changes 1 into Tag among the transparent data ats_cfu.

Step 107, HSS Gen Ju ﹠amp; ﹠amp; , what affirmation needed visit is the transparent data of TLV form, with reference to the TLV form, according to the path (Tag is 4) of this TLV element, searches corresponding TLV element 000400010 in this transparent data, and this TLV element is revised as 000400011.

Consult Fig. 2, the embodiment of the invention two provides a kind of transparent data management method, and this method comprises:

Step 201, AS generate the transparent data element that meets the TLV form and store with this paper form according to data dictionary.

The realization of this step is identical with step 101, does not repeat them here.

Step 202, AS send Data Update request (Profile Update Request to HSS, PUR), the AVPExt-Service-Indication that AVP User-Data among this PUR is carried on the Sh interface to be increased and each element of transparent data comprise among the AVP Ext-Service-Indication that the AVP and the newly-increased described transparent data of expression of expression transparent data sign is the AVP of TLV form.

AVP Ext-Service-Indication is defined as follows:

Ext-Service-Indication::＝<AVP?header：711?10415>

{Service-Indication}

[Format]

[Selector]

*[AVP]

For making present embodiment clear, to the definition of the above-mentioned AVP Ext-Service-Indication explanation that makes an explanation: AVP Ext-Service-Indication comprises at least: AVP Service-Indication, be AVPSI, can also comprise AVP Format, AVP Selector.

Wherein, the type of AVP SI is character string OctetString, and it identifies a transparent data as the index of transparent data.The type of AVP Format is enumeration type Enumerated, its indication transparent data data format, its value can for:

Unstructured (0), XML (1) or TLV (2)

Wherein, the form of Unstructured (0) expression transparent data is a non-structure.If format is a non-structure, then the value of Selector is invalid.The form of XML (1) expression transparent data is XML.The form of TLV (2) expression transparent data is TLV.If do not carry Format, the form of the transparent data of acquiescence is the non-structure data.

The value of Unstructured (0) expression AVP Format can be Unstuctured or 0, and promptly Unstructured or 0 can represent that the form of transparent data is a non-structure; In like manner, XML or 1 can represent that the form of transparent data is XML; TLV or 2 can represent that the form of transparent data is TLV.

The type of AVP Selector is OctetString, and it is used to refer to the path of element in the transparent data, and is only effective for the transparent data of XML or TLV form.For the transparent data of TLV form storage, the general format of Selector is: Tag1/Tag2.

When having the identical TLV element of a plurality of Tag1 values TLV element identical with the Tag2 value, then the path of daughter element is: Tag1[n]/Tag2[m].

Though newly-increased AVP Ext-Service-Indication can substitute original Service-Indication fully, but for back compatible, still can keep ServiceIndication, the implication that promptly can keep Service-Indication is constant, with existing standard, if use ServiceIndication visit transparent data, think that so the form of transparent data is unstructured, and can only visit the transparent data of monoblock, and can not visit the segment of transparent data.

Initially send PUR message for AS in this step to HSS, so that HSS preserves the TLV element that is generated, carry AVP User-Data in this PUR message, carry AVPExt-Service-Indication among this AVP User-Data, can not comprise Selector AVP for the AVP Ext-Service-Indication in this step.The example of continuous above-mentioned Call Forwarding Unconditional business, AVP Ext-Service-Indication comprises:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

000300011

000400010

000500011

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Wherein,＜ServiceIndication〉ats_cfu＜/ServiceIndication〉represent that the transparent data of visit is designated ats_cfu,＜Format〉tlv＜/Format〉represent that this transparent data is the TLV form.

Step 203, HSS preserve each element of the transparent data of this TLV form, and each element that can be called the transparent data of TLV form is the TLV element.

Step 204, when AS need read TLV element in the transparent data, AS sends user data requests (user-data-request to HSS, UDR), carry the service identification AVP Ext-Service-Indication of property value in the UDR message to expansion, AVP Ext-Service-Indication comprises the AVP SI of expression transparent data sign, the newly-increased described transparent data of expression is the AVP Format of TLV form and the AVP Selector in the element path that newly-increased expression need be read, wherein, AVP SI (value is ats_cfu), AVP Format (value is tlv), AVP Selector (value is 4).

Step 205, HSS basis＜Format〉tlv＜/Format 〉, need to confirm the transparent data of visit TLV form, with reference to the TLV form, path (AVP Selector value is 4) according to this TLV element, in transparent data ats_cfu, search corresponding TLV element 000400010, return UDA message to AS, the value of the AVP User-Data in this message is:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

<any>

000400010

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Above-mentioned steps 204-step 205 does not have sequencing with follow-up step 206-step 207, does not influence realization of the present invention.

Step 206, when AS need write TLV element of transparent data, AS sends Data Update request (profile-update-request, PUR), wherein, AVP User-Data among the PUR comprises that AVP SI, the newly-increased described transparent data of expression of expression transparent data sign are the pairing new elements of AVP Selector and described path in the path of the AVPFormat of TLV form, the newly-increased expression element that need upgrade, and are specially:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

<any>

000400011

</any>

</ServiceData>

</RepositoryData>

</Sh-Data>

Step 207, HSS basis＜Format〉tlv＜/Format 〉, need to confirm the transparent data of visit TLV form, with reference to the TLV form, path (the Selector value is 4) according to this TLV element, in transparent data ats_cfu, search corresponding TLV element 000400010, this TLV element is revised as 000400011.

Consult Fig. 3, the embodiment of the invention three provides a kind of data managing method, comprising:

Step 301, when AS need subscribe in the transparent data TLV element, AS sends the subscribing notification message of carrying expansion SI to HSS, and (subscribe-notifications-request, SNR), expansion SI exists with the form of AVP SI in SNR message.In SNR message, increase a sign AVP NotifyFormat who is used to indicate the sending out notice form newly, its value can be one of following four enumerated values,

ALL-DATA (0) requires to return complete transparent data.This is the mode of stipulating in the present 3GPP standard;

CHANGED-DATA-AND-PATH (1), the variation element of transparent data is only returned in requirement, the path of pointing out this variation element more simultaneously.

CHANGED-DATA (2) requires HSS to return all elements, changes for element data, returns the element after the variation, and is unchanged for element data, then returns the sky element.

CHANGED (3) only notifies the AS transparent data to change this incident, does not return actual data, requires this moment HSS to return the ServiceData element of a sky, only represents that transparent data changes.

Step 302, when element changes in the pairing transparent data of the SI that HSS preserved, according to AVP NotifyFormat, return sending out notice message PNR (push-notification-request) to AS, the SI that expands in this message exists with the form of XML element S I, with element variation in this transparent data of notice AS.

For the TLV form is that example is illustrated, the former transparent data among the HSS is as follows with the transparent data in following elder generation: (Type accounts for 4 bytes, and length accounts for 4 bytes)

</ServiceData>

</RepositoryData>

</Sh-Data>

Wherein, carried complete transparent data among the AVP User-Data, wherein Tag is that the value of 3 TLV element is 999.

2), when the value of AVP NotifyFormat is CHANGED-DATA-AND-PATH (1), if the mode that adopts embodiment one to be provided, AVP User-Data comprises AVP SI and changes the back element that the AVP SI of expansion comprises the transparent data sign and change the path of element that concrete is:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

00030003999

</ServiceData>

</RepositoryData>

</Sh-Data>

If the mode that adopts embodiment two to be provided, AVP User-Data comprises that the AVP SI of expression transparent data sign, newly-increased expression change the pairing variation of AVP Selector and the described path back element in element path, are specially:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<Sh-Data>

00030003999

</ServiceData>

</RepositoryData>

</Sh-Data>

Wherein, carry the variation element (00030003999) of transparent data among the AVP User-Data, pointed out the path (Tag is 3) of this variation element simultaneously.

3), the value as AVP NotifyFormat is CHANGED-DATA (2), if the mode that adopts embodiment two to be provided, AVP User-Data comprises that AVP SI, the element after the variation and the sign of expression transparent data sign do not change the empty element of element, are specially:
