Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
This notion of interpreting user pattern at first.User model is meant that mainly the user enters normally service routine of portable terminal, but is bound to this user name for sensitive datas such as addressable phone directory, note, email, documents.Distinguish for the ease of each user, portable terminal needs the situation of a plurality of cards of user of management processing, guarantees that each card can effectively start this user account number.
Scheme one:
Generally, no matter be gsm system or cdma system, mobile phone users can obtain a subscriber card (as the SIM card of gsm system or the UIM card of cdma system) when " networking ", this card can insert in any portable terminal that meets GSM standard or CDMA standard.International mobile subscriber identification code (IMSI) is the user identification code that is stored in the subscriber card, is convenient to communication system the identity of mobile phone users is verified, each opens all corresponding unique IMSI of subscriber card.
This programme can be created a user list according to this uniqueness of IMSI at portable terminal, according to different IMSI, creates different users.To this user list, portable terminal is kept in the memory block by the mode of encrypting, and to guarantee enough fail safes, prevents the hacker or illegally reads.
Like this, when inserting different subscriber cards in portable terminal, portable terminal can read the IMSI on this card automatically, and according to tabulation, judges whether to exist this user.
As shown in Figure 1, be the schematic flow sheet of this scheme, as seen from the figure, mainly may further comprise the steps:
S11, portable terminal read the first subscriber card information, obtain first user identification code.
S12, portable terminal mate information in described first user identification code and the user list, search first user of the described first user identification code correspondence, after matching first user, enter step S13; Otherwise, progressive step S14.
S13, portable terminal are that first user starts user model.
S14, portable terminal are that first user starts client's pattern.
In step S12, if there is first user profile, then verify described first user's the user name and password, after described first user's the user name and password passes through checking, then portable terminal is enabled this user model, all information and the data that allow this first user of visit to store in portable terminal.If there is not this first user profile, portable terminal is enabled client's pattern, and IMSI number of this card joined in the predefined guest user name.
