The method comprises the following steps: initializing all the available file entries of a phone book dynamically in the initialization of the phone book, analyzing and storing the relevant information of the entries of the phone book into a data buffer area of the phone book; when reading and processing the entries of the phone book, searching the information of the operated entries in the buffer area firstly, then reading the relevant available file entries directly according to the known information, processing and returning a result; and the invention avoids operating empty entries and reduces the operation redundancy and the time delay, thereby quickening the response speed of the user terminal during searching the entries of the phone book.
Description
Technical field
The present invention relates to the communications field, particularly a kind of method for quickly reading entries of phone book of user terminal.
Background technology
Common user identification card (abbreviating USIM as) is the important composition unit of third generation wirelessmobile communication system user terminal (abbreviating 3G UE as, for example mobile phone, data card).Relevant file and the attribute of all telephone directories that is stored in the usim card described in 3GPP agreement TS31.102 document, as shown in table 1 below:
Relevant file attribute and the type of telephone directory in the table 1:USIM card
| File | File description | File type |
| EFADN | Master file, content of text of storing call book (name) and number | Type1 |
| EFEXT1 | Telephone number residue character (＞=21) or subaddressing | Type3 |
| EFANR | The index of addition number and classification, maximum three files | Type1 or Type2 |
| EFAAS | The classification character string of addition number | Type3 |
| EFSNE | Another name | Type1 or Type2 |
| EFGRP | The index of group's name | Type1 |
| EFGAS | Group's name content | Type3 |
| EFEMAIL | The e-mail address content | Type1 or Type2 |
| EFCCP1 | Bearing capacity | Type3 |
| EFUID | User totem information | Type1 |
| EFIAP | Index management, related Type2 type file | Type1 |
| EFPBC | Control with hide Info | Type1 |
Wherein, It is constituent instruments for EF (Elementary File) prefix designates; The information of EFADN file storage is called the householder's information of using; Canned data in EFEXT1, EFCCP1, EFSNE, EFANR, EFAA, EFEMAIL, EFGRP and the EFGAS file is called user's satellite information, has constituted the user profile of telephone directory jointly with householder's information and user's satellite information.
Wherein, three kinds of document type definitions are following:
The file of type1 type comprises the clauses and subclauses with master file EFADN equal number, is index with the master file entry number, with entry number link (being the interrelated correspondence of clauses and subclauses of identical numbering);
The file of type2 type, the no more than master file EFADN of its entry number number of entries realizes related with the EFADN clauses and subclauses through index management file (EFIAP);
The file of type3 type is quoted by type1 or type2 type file, through the link of the sign of the clauses and subclauses in these reference document clauses and subclauses;
EFANR, EFSNE and EFEMAIL file can be type1 or type2 type file.
The phonebook subscribers information of in usim card, being stored comprises: major number and name thereof; And bearer capability information (being kept in file EFADN, EFEXT1 file and the EFCCP1 file); With the corresponding another name (being kept in the EFSNE file) that also comprises of major number; One or more addition numbers (being kept in the EFANR file) and classification (being kept in the EFAAS file) thereof; A plurality of e-mail addresses (being kept in the EFEMAIL file), with and affiliated a plurality of groups (being kept in EFGRP and the EFGAS file).In addition ID (be kept in EFUID file), index management (be kept in EFIAP file), control and the hide Info management information such as (are kept in EFPBC file) relevant with this personal information.
Shown in Figure 1 is a kind of possible corresponding relation of telephone directory file; The file that wherein is all the type1 type with master file EFADN also has EFIAP, EFPBC, EFGRP, EFANRA, EFEMAIL and EFUID; Wherein 1:1 representes corresponding one by one; Be that they have identical number of entries (as all being 254), and related with the clauses and subclauses sequence number, corresponding like the 3rd record of EFADN with the 3rd record of other type1 type files; Two type2 file: EFSNE and EFANRB are arranged, and they are provided to the association (type1 quotes type2) of EFADN file by the EFIAP file; The type3 file is: EFEXT1, EFCCP1, EFGAS, EFAAS, wherein EFEXT1 and EFCCP1 by the EFADN clauses and subclauses directly quote, EFGAS by EFGRP quote, EFAAS quoted (type1 quotes type3) by the EFNRA file.X, Y, Z, W represent that this document number of entries is confirmed by usim card but necessarily less than type1 type file entry number.
Two kinds of telephone directory types of universal telephone book and application phone book are arranged in the usim card.They have identical file structure, can exist individually or simultaneously, and just the application phone book can only be by the USIM application access.When two kinds of telephone directory books existed simultaneously, they were separate, do not have data sharing.When 3G UE starts shooting, the telephone directory type that the user can instruct (a kind of information communication mode and communication standard are called for short the AT instruction) selection to use through ATTENTION.The AT command function that 3GPP R7 and above release protocol telephone directory are relevant; Requirement is when carrying out the telephone directory read operation; After having read, also need read user's satellite information, and will integrate later phonebook subscribers information and use the AT commanded response to return with householder's information.
When 3G UE starts shooting, with the initialization of at first accomplishing telephone directory.The initialization of telephone directory mainly be obtain all with householder's information and satisfy the query function (mainly comprise total entry number of phonebook subscribers information, use the maximum length etc. of entry number, telephone number and name) of AT instruction and accomplish telephone directory synchronously (the called phone book synchronously; Be meant if after usim card phonebook subscribers information is modified in second generation wirelessmobile communication system user terminal (abbreviating 2G UE as); When this UISM card was inserted into 3G UE subsequently, 3G UE can discern this modification).For this reason, need all EFADN and EFEXT file entries be read one time at least during initialization.After initialization was accomplished, the user just can read, preserve, upgrade telephone directory or deletion etc. has been operated.
File relation with shown in Figure 1 is an example, and the telephone directory read method is (as shown in Figure 2) in the prior art:
At first, read corresponding EFADN clauses and subclauses, judge that whether these clauses and subclauses are empty, if sky then finishes to read, otherwise obtain major number and name information wherein.And when the EFADN clauses and subclauses have been quoted the type3 file entries; Read corresponding EFCCP1 and EFEXT1 file entries respectively according to ability/configuration identifier in the EFADN entry contents and extension record sign, to obtain bearing capacity parameter information and major number additional data/extension number information; Secondly; Handle EFANRA, EFANRB, EFANRC, EFEMAIL, EFSNE, EFGRP file (when handling, obtaining file type earlier for EFANR, EFEMAIL, EFSNE) successively if exist the type2 type file then need read corresponding EFIAP clauses and subclauses once.EFANRB and EFSNE are the type2 type file in Fig. 1, contain corresponding EFANRB and EFSNE entry number in the EFIAP entry contents, before reading EFANRB, need read the EFIAP file entries earlier and preserve its content.Then directly read corresponding clauses and subclauses for EFANRA, EFANRC, EFEMAIL, EFGRP according to the EFADN entry number.In this process, then read corresponding type3 file entries if there is the type3 type file to be cited.At last, with all information analyses and assembling, return the entries of phone book result.
In above processing mode, when specified entry use householder's information as sky the time, with the satellite information that no longer reads the user; When with householder's information non-NULL, whether be empty owing to do not know user's satellite information, can carry out above all flow processs.But when one or several even full detail clauses and subclauses of user's satellite information when being empty; Also can read whole satellite information clauses and subclauses; This is nonsensical to reading of empty user's satellite information, and the telephone directory of prior art reads flow process and has operational redundancy and time delay, particularly when many entries of phone book are read in an AT instruction; This operational redundancy and time delay will be exaggerated, and cause the user terminal response untimely.
Summary of the invention
Read redundancy and time delay in the process for overcoming the existing telephone book, cause the untimely problem of user terminal response, the present invention proposes a kind of method for quickly reading entries of phone book.
The present invention proposes a kind of method for quickly reading entries of phone book; It is characterized in that; All available phone book file entries of dynamic initialization in the telephone directory initialization procedure are analyzed and the relevant information of storing call book clauses and subclauses arrives in the telephone book data buffer area (hereinafter to be referred as buffer area); When entries of phone book is read processing, at first inquire about, directly read relevant file available clauses and subclauses according to Given information again, handle and return results by the information of operation entries at buffer area.
The present invention to all file available clauses and subclauses, carried out dynamic initialization, and initialization information is stored in the buffer area before reading entries of phone book; Elder generation's query entries information in buffer area when reading entries of phone book; Avoided directly reading the information of respective entries, do not read and be designated empty clauses and subclauses, avoided operation empty clauses and subclauses; Reduce operational redundancy and time delay, and then accelerated the response speed of user terminal when entries of phone book.

Preferably, said in the telephone directory initialization procedure all available phone book file entries of dynamic initialization can adopt following method (see figure 4):
At first; Initialization EFADN file, the method (see figure 5) is: read all EFADN file entries, judge whether entry contents is empty; If sky is mark then; If not empty then writes down the EFEXT1 corresponding with the EFADN clauses and subclauses, EFCCP1 file entries numbering (unreferenced EFEXT1 or EFCCP1 clauses and subclauses are then represented this numbering with 0), and the number of times that is cited of renewal EFEXT1, EFCCP1 file entries, reads completion up to all EFADN clauses and subclauses.
Secondly; Other type1 type files of initialization EFIAP, EFEMAIL, EFPBC, EFGRP and EFUID, the method (see figure 6) is: judge that earlier whether corresponding EFADN clauses and subclauses are empty, just read corresponding clauses and subclauses when having only its non-NULL; Judge again whether entry contents is empty, and mark; If the clauses and subclauses non-NULL, need write down its entry contents (both the EFANR of its index and EFSNE entry number, index is not then represented to number with 0) for EFIAP, for the EFGRP EFGAS entry number of record reference (unreferenced then use 0 represent) then.
Once more; Initialization type2 type file; Comprise EFANR and EFSNE file; The method (see figure 7) is: judge that these clauses and subclauses whether by EFIAP index (according to the EFANR and the EFSNE entry number of EFIAP index in the buffer area), read these more successively and number corresponding clauses and subclauses (both not gone to read by the clauses and subclauses of index) earlier, judge whether entry contents is empty and mark.If clauses and subclauses non-NULL; For the corresponding EFEXT1 of its clauses and subclauses of EFANR file mark, EFCCP1 and EFAAS file entries numbering (unreferenced then use 0 expression); Whether and upgrading the number of times that EFEXT1, EFCCP 1 and EFAAS file entries numbering are cited, is empty for EFSNE mark.
At last, initialization type3 type file method (see figure 8) is: only judge whether file content is empty, and mark.
In above process, the information that reads is analyzed and association, and preservation information is in buffer area; Being saved in buffer area information comprises: whether the file type information of EFANR, EFSNE and EFEMAIL, EFADN file be with entry number and total entry number, the EFEXT1 corresponding with the EFADN clauses and subclauses, EFCCP1 file entries numbering (if EFEXT1 and EFCCP1 clauses and subclauses are not cited, then entry is numbered 0), All Files the clauses and subclauses sign, EFIAP file content, EFEXT1, EFCCP1 and the EFAAS file entries numbering (as if unreferenced then reference numeral is 0) corresponding with the EFANR clauses and subclauses, the EFGAS entry number (as if unreferenced then reference numeral is 0) corresponding with the EFGRP file, the number of times that the type3 clauses and subclauses are cited of non-NULL.
Said buffer area upgrades with user's operation; Comprise: when newly-increased or modification phonebook subscribers information; File entries according to the AT command content analysis needs operation that issues upgrades corresponding entries of phone book content then, if any file needs newly-increased clauses and subclauses; The corresponding clauses and subclauses of buffer area are set to the non-NULL sign after then upgrading successfully, and correlation of relevant information; Then keep buffer area information if only revise entry contents; When deletion phonebook subscribers information, needing to obtain the entry number of deletion from buffer area, delete successfully after the corresponding clauses and subclauses of buffer area be set to sky and identify, and correlation number is put 0.
Said buffer area upgrades with user's operation, will upgrade the back information storage in mobile phone EMS memory or client software, detects Subscriber Identity Module when starting shooting once more and does not change, and then directly reads this buffer area and promptly accomplishes the telephone directory initialization, so that quick turn-on.
Step B: when entries of phone book is read processing, at first inquire about, directly read relevant file available clauses and subclauses according to Given information again, handle and return results the following (see figure 9) of detailed process by the information of operation entries at buffer area:
Receive the AT instruction of reading phonebook subscribers information, therefrom take out the entries of phone book that will read; Judge earlier according to entry number whether corresponding EFADN clauses and subclauses are empty, and empty in this way clauses and subclauses then finish to read; As be not that the sky clauses and subclauses then at first read the EFADN file entries, if its corresponding EFEXT1 and EFCCP1 file entries numbering is not 0 and reads this clauses and subclauses in the buffer area; Obtain corresponding EFIAP entry contents to obtain related EFANR and EFSNE file entries numbering from buffer area; And read corresponding clauses and subclauses (if numbering 0 do not read) by these numberings, if the EFANR clauses and subclauses have been quoted EFEXT1, EFCCP1 and EFAAS file entries and have then been read these clauses and subclauses; Judge whether non-NULL of corresponding EFEMAIL clauses and subclauses by buffer area information, if not empty then reads this EFEMAIL clauses and subclauses, obtains the EFGAS entry number that the EFGRP clauses and subclauses quote by buffer area then and reads; Integral data is returned the response of reading of a phonebook subscribers information.
It will be apparent to those skilled in the art that and understand that the above embodiment that the inventive method is lifted only is used to explain the present invention, and is not limited to the present invention.Though effectively described the present invention through embodiment; Those skilled in the art will know that; There are many variations in the present invention and do not break away from spirit of the present invention; Under the situation that does not deviate from spirit of the present invention and essence thereof, those skilled in the art work as can make various corresponding changes or distortion according to the inventive method, but these corresponding changes or distortion all belong to claim protection range of the present invention.
