Abstract:
Method for assisting load-balancing of subscriber sessions in a distributed mobile gateway (e.g. PGW, SGW, ePDG, or TWAG) comprising a plurality of distributed gateway instances (DGIs) is disclosed. Method includes receiving an advertisement of GTP fully qualified tunnel endpoints identifications (F-TEIDs) allocated to a first plurality of subscriber sessions, the sessions assigned to a first DGI of the DGIs. The advertisement indicates the first DGI as a recipient for data provided to the gateway and related to any of the first plurality of sessions. Method further includes storing an association between the GTP F-TEIDs of the advertisement and the first DGI, receiving a packet comprising data related to a subscriber session of the first plurality of sessions, identifying a F-TEID for the data of the received packet, identifying from stored association, that the F-TEID is associated with the first DGI, and forwarding data of the packet to the first DGI.
