1. A method for storing a communication log in a subscriber identity module/user identity model, comprising:
after communicating with a phonebook contact person in the subscriber identity module/user identity model, formatting time and duration information of a current communication according to a preset communication log format, and obtaining and caching a byte stream of a current communication log; writing the cached byte stream of the current communication log into an EF_EXT1 file of the subscriber identity module/user identity model, and using a communication type identifier corresponding to the current communication to categorize the current communication log; wherein, after the step of writing the cached byte stream of the current communication log into the EF_EXT1 file of the subscriber identity module/user identity model, the method further comprises: using a last byte of the current communication log to index a next communication log of the phonebook contact person, if the current communication log is a first communication log of the phonebook contact person, using a last byte of a communication log in an abbreviated dialing number log (ADN) file to index the current communication log of the phonebook contact person to make the indexes of communication logs of the phonebook contact person in series. |
