Trace receiver and MME receiver service for RAN parser
A method includes receiving a data stream from a mobile network having one or more vendor's equipment and one or more wireless technologies; decoding a message from the data stream based on what port the message was received on, wherein the port is used to automatically detect how the decoding performs based on one or more of vendor's equipment and wireless technology; converting the message to a common output format based on the decoding, wherein the common output format is a same format for the one or more vendor's equipment and the one or more wireless technologies; and providing the message in the common output format for subsequent processing.
1 . A method comprising steps of:
receiving a Transmission Control Protocol (TCP) data stream comprising Call Traces in vendor-proprietary formats from a mobile network having one or more vendor's equipment and one or more wireless technologies;
decoding a message from the data stream via one of a plurality of vendor- and technology-specific decoder types based on what network port the message was received on, wherein the port is used without analyzing content of the data stream and based on an operating-system determination to automatically decide which type of decoder must be used and detect how the decoding performs based on one or more of vendor's equipment and wireless technology;
converting the message to a vendor/technology-agnostic common output format based on the decoding, wherein the common output format is a same format for the one or more vendor's equipment and the one or more wireless technologies; and
providing the message in the common output format for subsequent processing.
2 . The method of claim 1 , wherein the steps further include:
load balancing messages within the data stream after the receiving and prior to the decoding, to provide messages from the data stream to one of a plurality of services.
3 . The method of claim 2 , wherein the load balancing is performed automatically in a round-robin fashion without analyzing the messages.
4 . The method of claim 1 , wherein the steps further include:
determining messages are part of a same call based on a computed identifier.
5 . The method of claim 4 , wherein the computed identifier is based on a plurality of technology, Mobile Country Code, Mobile Network Code, base station identifier, a first fragment, and a second fragment, wherein each of the first fragment and second fragment are vendor specific.
6 . The method of claim 1 , wherein the steps further include:
performing data enrichment to add information not present in the message.
7 . The method of claim 6 , wherein the enrichment includes inferring a node identifier from information in the message and other messages having a same combination of Internet Protocol (IP), port, and Transmission Control Protocol (TCP) stream identifier.
8 . The method of claim 6 , wherein the enrichment includes a message direction determined based on a type of the message, vendor specifications, and standard message specifications.
9 . The method of claim 6 , wherein the performing data enrichment includes one or more of:
calculating to change units to the same format,
transforming a date format to the same format,
combining several inputs into one output, and
splitting one input into several outputs.
10 . The method of claim 1 , wherein the decoding and the converting are performed by one of a Trace Receiver Service and a Mobile Management Entity (MME) Receiver Service.
11 . The method of claim 10 , wherein the Trace Receiver Service operates on main Call Traces and the MME Receiver Service operates on additional Call Traces containing user identity information of users performing calls.
12 . The method of claim 1 , wherein the steps further include:
performing the subsequent processing in a vendor/technology agnostic manner.
13 . The method of claim 1 , wherein the receiving is performed at an edge location in the mobile network.
14 . A processing system comprising:
one or more processors; and
memory storing instructions for programming the one or more processors to
receive a Transmission Control Protocol (TCP) data stream comprising Call Traces in vendor-proprietary formats from a mobile network having one or more vendor's equipment and one or more wireless technologies;
decode a message from the data stream via one of a plurality of vendor- and technology-specific decoder types based on what network port the message was received on, wherein the port is used without analyzing content of the data stream and based on an operating-system determination to automatically decide which type of decoder must be used and detect how the decoding performs based on one or more of vendor's equipment and wireless technology;
convert the message to a vendor/technology-agnostic common output format based on the decoding, wherein the common output format is a same format for the one or more vendor's equipment and the one or more wireless technologies; and
provide the message in the common output format for subsequent processing.
15 . The processing system of claim 14 , wherein the instructions further program the one or more processors to:
perform the subsequent processing in a vendor/technology agnostic manner.
16 . The processing system of claim 14 , wherein the data stream is received at an edge location in the mobile network.
17 . The processing system of claim 14 , wherein the instructions further program the one or more processors to:
perform data enrichment to add information not present in the message.
18 . A non-transitory computer-readable medium comprising instructions for programming one or more processors to perform steps of:
receiving a Transmission Control Protocol (TCP) data stream comprising Call Traces in vendor-proprietary formats from a mobile network having one or more vendor's equipment and one or more wireless technologies;
decoding a message from the data stream via one of a plurality of vendor- and technology-specific decoder types based on what network port the message was received on, wherein the port is used without analyzing content of the data stream and based on an operating-system determination to automatically decide which type of decoder must be used and detect how the decoding performs based on one or more of vendor's equipment and wireless technology;
converting the message to a vendor/technology-agnostic common output format based on the decoding, wherein the common output format is a same format for the one or more vendor's equipment and the one or more wireless technologies; and
providing the message in the common output format for subsequent processing.
19 . The non-transitory computer-readable medium of claim 18 , wherein the steps further include:
performing the subsequent processing in a vendor/technology agnostic manner.
20 . The non-transitory computer-readable medium of claim 18 , wherein the receiving is performed at an edge location in the mobile network.
