Abstract
A method and apparatus for network accessing configured to prefix filtering one or more wildcard identity for an International Mobile Subscriber Identity (“IMSI”) application is disclosed. Upon receiving a request of a new rule with system identification (“SID”) for network access, a process of wildcard prefixing is able to identify a wildcard in a predefined field of the SID. The SID, in one example, is an IMSI. After retrieving a specific prefix in accordance with the wildcard, the wildcard is replaced with the specific prefix in the predefined field of the SID to form a modified rule. The predefined field of the SID can be a field for mobile country code (“MCC”), mobile network code (“MNC”), or mobile subscriber identification number (“MSIN”). The process subsequently inserts the modified rule into a memory structure.
