Method, system, and access gateway for traffic flows to share resources

摘要

Embodiments of the present invention provide a method, a system, and an access gateway for traffic flows to share resources. The method for traffic flows to share resources includes obtaining information of at least two traffic flows and resources requested by the at least two traffic flows, where the at least two traffic flows correspond to different Internet Protocols connections. The at least two traffic flows share the resources. The information of the at least two traffic flows is bound on an established data channel. Resources for the data channel are allocated according to the resources requested by the at least two traffic flows. The at least two traffic flows are beared on the data channel.

1. A method for traffic flows to share resources, comprising:
obtaining information related to a plurality of traffic flows and resources requested by the traffic flows, wherein the traffic flows correspond to different Internet Protocol (IP) connections and the traffic flows share the resources; binding the information of the traffic flows on an established data channel; allocating resources for the data channel according to the resources requested by the traffic flows; and bearing the traffic flows on the data channel; the bearing comprising sharing, by a Packet Data Network (PDN) connections corresponding to the traffic flows, a wireless bearer and an S1 default bearer, the sharing comprising receiving an additional PDN connection creating request for establishing a second PDN connection, wherein the additional PDN connection creating request comprises an Access Point Name (APN) and a Linked Bearer Identity (LBI) which are used for establishing a first PDN connection, and sending the additional PDN connection creating request for establishing the second PDN connection to a Packet Data Gateway (PGW) so that the PGW establishes the second PDN connection according to the additional PDN connection creating request, wherein the first PDN connection and the second PDN connection share the wireless bearer and the S1 default bearer; receiving an additional PDN connection deletion request, wherein the additional PDN connection deletion request carries the APN and LBI that are used for establishing the first PDN connection and an IP address required to be deleted; and deleting the first PDN connection according to the additional PDN connection deletion request.
