Abstract

The invention discloses a packet data web gateway identification saving method and system in multi-access scene. The method includes that: when user equipment simultaneously accesses a packet data network by two access networks, namely a first access network and a second access network, and the identical packet data network connection is established, an affiliation user or authentication charging server saves the identification of the packet data web network; the first access network is a third generation partner plan 3GPP access network, and the second access network is a non-3GPP access network; or the first access network is a non-3GPP access network, and the second access network is a 3GPP access network; when releasing the access of one access network of the two access networks, the affiliation user or authentication charging server saves the identification of the packet data web gateway. The method can reasonably notify HSS / AAA, P-GW identification can be correctly stored or deleted, and the system is ensured to normally operate in related P-GW identification operation in multi-access scene.
