METHOD AND SYSTEM FOR SCALABLE AND MANAGEABLE NON-ACCESS STRATUM (NAS) NODE SELECTION FUNCTION FOR EVOLVED PACKET SYSTEM |
摘要 |
A network element having a Non-Access Stratum (NAS) Node Selection Function for discriminating information in order to determine which core network node a signaling message should be sent comprising: a network interface unit configured to interact with a packet network system; a processor with a memory associated with the network interface unit and adapted to: receive the signaling message from an eNB at a selection function; extract header information from Stream Control Transport Protocol (SCTP) of the signaling message; communicate with a database having a persistent application map to determine if there is an association between the header information and a core network entity; if there is an association, forward the signaling message to a selected core network entity; and determine at the selected core network entity which one of a plurality of core network nodes within a core network pool to route the message based on availability of the plurality of core network nodes. |

1. A network element having a Non-Access Stratum (NAS) Node Selection Function for discriminating information in order to determine which core network node a signaling message should be sent comprising:
a network interface unit configured to interact with a packet network system; a processor with a memory associated with the network interface unit and adapted to: receive the signaling message from an eNB at a selection function; extract header information from Stream Control Transport Protocol (SCTP) of the signaling message; communicate with a database having a persistent application map to determine if there is an association between the header information and a core network entity; if there is an association, forward the signaling message to a selected core network entity; and determine at the selected core network entity which one of a plurality of core network nodes within a core network pool to route the message based on availability of the plurality of core network nodes. |
