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

Abstract
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.

11. An access gateway, comprising:
-
an obtaining module, configured to obtain 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, configured to receive a resource request from a Policy Charging Rule Function (PCRF) entity and wherein the resource request comprises the information related to the traffic flows, the information corresponding to different IP addresses of a User Equipment, the request also comprising the resources requested by the traffic flows and a relationship of the traffic flows sharing the resources, and configured to receive a resource request from a PCRF entity, the resource request comprising information of a traffic flow of a User Equipment and resources requested by the traffic flow to generate the information of the traffic flows corresponding to different IP addresses and the relationship of the traffic flows sharing the resources according to the information of the traffic flow and a recorded relationship of different IP addresses of the User Equipment sharing a data channel and to obtain the resources requested by the traffic flows according to the resources requested by the traffic flow; a binding module, configured to bind the information obtained by the obtaining module on an established data channel; an allocation module, configured to allocate resources for the data channel according to the resources obtained by the obtaining module and requested by the traffic flows; a bearing module, configured to bear the traffic flows on the data channel; and a deleting module, configured to map information, which is carried in a proprietary bearer deletion request and is of a traffic flow required to be deleted, to an S1 proprietary bearer which is already established; and
to send a bearer update request to a Mobility Management Entity, wherein the bearer update request carries information of an updated traffic flow after the information, of the traffic flow required to be deleted, is deleted, so that the Mobility Management Entity deletes, according to the bearer update request, the S1 proprietary bearer corresponding to the information of the traffic flow required to be deleted;
orconfigured to map the information, in a received session resource request sent by the PCRF entity, of the traffic flow required to be deleted to an IPSec tunnel, and to delete the information of the traffic flow required to be deleted. - View Dependent Claims (12, 13, 14)

15. A system for traffic flows to share resources, comprising:
-
a Policy Charging Rule Function entity; and an access gateway; wherein the Policy Charging Rule Function entity is configured to send a resource request to the access gateway; and the access gateway is configured to receive the resource request sent by the Policy Charging Rule Function entity, and to obtain information of 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, to bind the information of the traffic flows on the established data channel, to allocate resources for the data channel according to the resources requested by the traffic flows; and
to bear the traffic flows on the data channel;wherein when the resource request comprises information of the traffic flows corresponding to different IP addresses of a User Equipment, the resources requested by the traffic flows, and a relationship of the traffic flows sharing the resources, the access gateway is configured to obtain, from the resource request, the information of the traffic flows corresponding to the different IP addresses of the User Equipment, the resources requested by the traffic flows, and a relationship of the traffic flows sharing the resources;
orwhen the resource request comprises information of a traffic flow of the User Equipment and resources requested by the traffic flow, the access gateway is configured to generate the information of the traffic flows corresponding to different IP addresses and the relationship of the traffic flows sharing the resources according to the information of the traffic flow and a recorded relationship of different IP addresses of the User Equipment sharing a data channel; and
to obtain the resources requested by the traffic flows according to the resources requested by the traffic flow; andwherein when the User Equipment initiates service migration to make a traffic flow on an IP address of the User Equipment migrate to another IP address, the Policy Charging Rule Function entity determines, according to a recorded binding relationship of different IP addresses of the User Equipment, that information of a traffic flow corresponding to the IP address of the User Equipment and information of a traffic flow corresponding to the another IP address share resources. - View Dependent Claims (16, 17, 18)
