Embodiment 2
Present embodiment mainly is how the descriptor of institute's swap data in the middle of the whole data exchange process to be generated describe, its purpose is by these descriptors, whether terminal can be checked before exchanges data can realize the function that exchanges, simultaneously after exchange is finished, check whether making a mistake, and can retransmit swap data according to whole descriptor request.
Data exchange process between whole terminal is as described in 2.2, and in the middle of whole exchange process, data interchange file adopts the form of XML, and related terminal data comprises the various subscriber datas such as telephone directory, schedule, short message, Multimedia Message and Email in the terminal.
Because the XML file mainly carries the data message of required exchange.In order to realize the purpose of present embodiment, we are divided into two parts with the data in the middle of the file in the middle of whole file structure, and a part is the header of XML file, and a part is the data message of required exchange.In the middle of the header of XML file, mainly comprise generation user, the equipment that data generate, the time that data generate, the software information that data generate, the language form in the middle of the data to data; In addition, also carry the quantity information of various different types of data.The information of this part must exist in the middle of each XML file that generates.
A part of in addition content is the data message of required exchange, and these information and concrete data are associated.Mainly comprise data such as telephone directory, schedule, short message, Multimedia Message and email message.The situation of these data based reality is as the different piece of XML file, simultaneously in the middle of exchange process, as these data of an XML file part, exchange if desired, can if do not participate in exchange, will not appear in the middle of the XML file as the part of XML so.In the middle of the whole data exchange process the concrete logical construction of data message referring to figure below:
The descriptor of institute's swap data in the middle of the above-mentioned header, just whole data exchange process.In order to describe his residing position in the middle of whole file clearly, we call it with header.Certainly, according to the needs of specific implementation, this information can be placed on each position of whole file, rather than is confined to the head of file, and therefore, the address of header neither be proprietary.
Terminal is carried out the header of the central XML file that is generated of data exchange process, adopt the mode of XML to be described, its purpose is the XML file in the middle of the whole exchange process is carried out describe, in general terms, and the while is also carried out overall description to the data message of swap data related in the middle of the XML file.Terminal can have the understanding of an integral body by reading this partial information to the whole data message that need exchange.
The information spinner of this part will comprise following content: user profile, client-side information, facility information, date and time information, language message etc.; In addition, also relate to the relevant information of concrete information, mainly comprise address book, schedule, short message, the items for information of Multimedia Message and email message.
It utilizes XML to encapsulate in the middle of the process of exchange, needs to observe following DTD:
In the middle of above-mentioned DTD
ELEMENT DataExchangeInfo identifies the header of whole data interchange file;
The UserInfo sign generates the user profile of data interchange file;
The UserAgent sign generates the client-side information of data interchange file;
The DeviceInfo sign generates the facility information of data interchange file;
The Date sign generates the date and time information of data interchange file;
The Language sign generates the language message of data interchange file;
The header of the data content that is comprised in the middle of the RecordInfo identification data file;
The bar number of the vCard data that the RecordOfvCard sign is exchanged;
The bar number of the vCalendar data that the RecordOfvCalendar sign is exchanged;
The bar number of the SMS data that the RecordOfSMS sign is exchanged;
The bar number of the MMS data that the RecordOfMMS sign is exchanged;
The bar number of the Email data that the RecordOfEmail sign is exchanged.

According to the flow process of the 2.2 central whole data exchange ways of being introduced, terminal need generate the intermediate file that is used for exchanges data.In the middle of the process that generates this intermediate file, need at first that user, equipment, software, date, language etc. are relevant information to be filled up in the middle of the whole descriptor.After this, in the XML form, also need the items for information with these data to be filled up in the middle of the whole descriptor in the data encapsulation that will need to exchange.
In the middle of the process of exchange, the purpose terminal at first reads the intermediate file in the middle of the exchange process.For the success of better guaranteeing to exchange, he reads whole description information of files, the header of the data file in the middle of this example just, thus obtain the generation person of whole file, information such as equipment, software, date and language.Read relevant data strip purpose descriptor afterwards again, for example, data strip purpose quantity, kind.If terminal is not supported the quantity of swap data clauses and subclauses, or do not support the kind of data clauses and subclauses, can refuse to carry out this exchanges data so, and will refuse the reason prompting user of this exchange.So just can avoid do not have under the situation of exchange capacity blindly carry out exchanges data, the generation that makes the mistake.
The error detection of terminal.After whole exchange takes place, such as in the middle of the process of exchange vCard.Newly-generated vCard clauses and subclauses after the exchange have 101, and only there are 100 in the clauses and subclauses in the middle of the file header information that in fact reads, be wrong generation in the middle of the so whole exchange process, terminal just should be abandoned this exchange process so, and the wrong generation of prompting user.
The mistake of terminal retransmits.If terminal detects wrong generation, and only be because the mistake that takes place in the middle of the local transmission, such as in the middle of the process of above-mentioned exchange vCard, newly-generated vCard clauses and subclauses after the exchange have 101, and only there is 100 example in the clauses and subclauses in the middle of the file header information that in fact reads; Rather than because local off-capacity does not perhaps have ability to carry out the words of exchanges data.Terminal can point out the user to initiate the process that exchanges again, retransmits thereby carry out mistake.
By the content of header, can allow the terminal resolution ability mate, error detection, the problem that mistake retransmits.
