Methods and apparatus to improve usage crediting in mobile devices

A tangible computer readable medium comprising instructions that, when executed, cause a machine to, at least:

• identify a first request having a first source port number, from a device;
• determine whether a second request, having a second source port number, is within a threshold number of ports from the first source port number;
• group the first and the second requests as a first session when the second source port number is within the threshold number of ports from the first source port number;
• and
• identify an application associated with the first session as a first application when a user agent of the first request matches a first application pattern associated with the first application, the first application pattern including a wildcard in a location corresponding to a numerical value in the user agent.

A method comprising:

• identifying, by executing an instruction with a processor, a first request having a first source port number, from a device;
• determining, by executing an instruction with the processor, whether a second request, having a second source port number, is within a threshold number of ports from the first source port number;
• grouping, by executing an instruction with the processor, the first and the second requests as a first session when the second source port number is within the threshold number of ports from the first source port number;
• and
• identifying, by executing an instruction with the processor, an application associated with the first session as a first application when a user agent of the first request matches a first application pattern associated with the first application, the first application pattern including a wildcard in a location corresponding to a numerical value in the user agent.
