Dear reader,
The charging ID is unique for every PDP context. It is generated by GGSN during the PDP context activation. What I fail to understand is:
- When there are multiple PDP context (Primary and secondary) from the same UE with different TEIDs, should the charging Id be different for two pdp contexts?
- If there is an update PDP context request from new SGSN during RAU, and if there is a new TEID(is it possible?), will the charging ID for the new tunnel be same?
Thank you for your response
