Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following describes the phonebook entry reading method of the present invention in further detail with reference to the accompanying drawings and embodiments.

[0031] Suppose with figure 1 The shown file relationship is taken as an example to illustrate, and the phonebook entry reading method of the present invention includes the following steps (see image 3 ):

[0032] Step A: Dynamically initialize all available phone book file entries in the phone book initialization process, analyze and store the relevant information of the phone book entries in the phone book data buffer area (hereinafter referred to as the buffer area);

[0033] Preferably, the following methods can be used to dynamically initialize all available phonebook file entries during the phonebook initialization process (see Figure 4 ):

[0034] First, initialize the EFADN file, method (see Fi...

Abstract

The invention relates to the field of communication, in particular to a method for quickly reading the entries of a phone book at a user terminal. 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 [0001] The invention relates to the field of communications, in particular to a method for quickly reading phone book entries for a user terminal. Background technique [0002] The Universal Subscriber Identity Card (referred to as USIM) is an important component of a user terminal (referred to as 3G UE for short, such as a mobile phone and a data card) in the third-generation wireless mobile communication system. All phonebook-related files and attributes stored in the USIM card are described in the 3GPP protocol TS31.102 document, as shown in Table 1 below: [0003] Table 1: File attributes and types related to the phone book in the USIM card [0004] document File Description file type EFADN The main file, which stores the text content (names) and numbers of the phonebook Type1 EFEXT1 Phone number remaining characters (>=21) or subaddress Type3 EFANR Index of additional numbers and categories...
