METHODS AND APPARATUS TO COLLECT CALL PACKETS IN A COMMUNICATIONS NETWORK

摘要

Methods and apparatus to collect call packets in a communications network are disclosed. An example method includes extracting data from packets captured at nodes in a communication network; storing the extracted data in a database in association with the voice data corresponding to the captured packets; searching, in response to a query including information, the extracted data in the database to identify records matching the information; identifying a second record in the database as belonging to a same unique voice call as the first record in the database based on determining that first metadata of the first record matches second metadata of the second record; and returning a first packet corresponding to the first record, a second packet corresponding to the second record, and a third packet comprising voice data corresponding to the same unique voice call in response to the query.

1. A method, comprising:
extracting data from packets captured at nodes in a communication network, the extracted data comprising data representative of voice calls in the communications network and the captured packets comprising control information and voice data; storing the extracted data in a database in association with the voice data corresponding to the captured packets; in response to a query including information describing a voice call, searching the extracted data in the database using a processor to identify records matching the information; in response to determining that a first record in the database matches the information, identifying, using the processor, a second record in the database as belonging to a same unique voice call as the first record in the database based on determining that first metadata of the first record matches second metadata of the second record; and returning, using the processor, a first packet corresponding to the first record, a second packet corresponding to the second record, and a third packet comprising voice data corresponding to the unique voice call in response to the query.
