VISITED PCRF S9 SESSION ID GENERATION
Various exemplary embodiments relate to a method performed by a network node for generating a S9 session ID, the method including: receiving, at the network node, an attachment request from a user equipment (UE); creating a DIAMETER session ID; attaching a timestamp and UE ID to the DIAMETER session ID resulting in a S9 session ID; and initiating a S9 session with a home PCRN using the S9 session ID.
1 . A method performed by a network node for generating a S9 session ID, the method comprising:
receiving, at the network node, an attachment request from a user equipment (UE);
creating a DIAMETER session ID;
attaching a timestamp and UE ID to the DIAMETER session ID resulting in a S9 session ID; and
initiating a S9 session with a home PCRN using the S9 session ID.
2 . The method of claim 1 , further comprising transmitting, by the network node, S9 messages relating to the UE using the S9 session ID.
3 . The method of claim 1 , further comprising receiving, by the network node, S9 messages relating to the UE using the S9 session ID.
4 . The method of claim 1 , wherein the UE ID is an International Mobile Network Identifier.
5 . The method of claim 1 , wherein the UE ID is a National Mobile Network Identifier.
6 . The method of claim 1 , wherein the UE ID is a Network Access Identifier.
7 . The method of claim 1 , wherein the timestamp indicates a time of the user equipment attachment request.
8 . The method of claim 1 , further comprising storing, by the network node, the S9 session ID.
9 . The method of claim 8 , further comprising truncating, by the network node, the S9 session ID prior to storing the S9 session ID.
10 . A tangible and non-transitory machine-readable storage medium encoded with instructions for execution by a network node for generating a S9 session ID, the tangible and non-transitory machine-readable storage medium comprising:
instructions for receiving, at the network node, an attachment request from a user equipment (UE);
instructions for creating a DIAMETER session ID;
instructions for attaching a timestamp and UE ID to the DIAMETER session ID resulting in a S9 session ID; and
instructions for initiating a S9 session with a home PCRN using the S9 session ID.
11 . The tangible and non-transitory machine-readable storage medium of claim 10 , further comprising instructions for transmitting, by the network node, S9 messages relating to the UE using the S9 session ID.
12 . The tangible and non-transitory machine-readable storage medium of claim 10 , further comprising instructions for receiving, by the network node, S9 messages relating to the UE using the S9 session ID.
13 . The tangible and non-transitory machine-readable storage medium of claim 10 , wherein the UE ID is an International Mobile Network Identifier.
14 . The tangible and non-transitory machine-readable storage medium of claim 10 , wherein the UE ID is a National Mobile Network Identifier.
15 . The tangible and non-transitory machine-readable storage medium of claim 10 , wherein the UE ID is a Network Access Identifier.
16 . The tangible and non-transitory machine-readable storage medium of claim 10 , wherein the timestamp indicates a time of the user equipment attachment request.
17 . The tangible and non-transitory machine-readable storage medium of claim 10 , further comprising instructions for storing, by the network node, the S9 session ID.
18 . The tangible and non-transitory machine-readable storage medium of claim 17 , further comprising instructions for truncating, by the network node, the S9 session ID prior to storing the S9 session ID.
