Embodiment Construction

[0028] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the described aspects may be practiced without these specific details.

[0029] As further described in the present invention, a mobile node (MN) can establish multiple sub-connections for multipath communication. For example, a MN may utilize multiple MN interfaces, where each MN interface may be connected to the same or a different network, in order to communicate with a correspondent node (CN). Based on this, the MN can centrally use (pool) the resources of these multiple MN interfaces when communicating with the CN, so as to increase the data throughput. The MN may advertise to a Home Agent (HA) a care-of-address (CoA) provided to the plurality of MN interfaces for communication in one or more visited n...

Abstract

Methods and apparatuses are provided that facilitate establishing multiple sub-connections between a correspondent node (CN) and a mobile node (MN), through a home agent (HA) to provide multipath functionality over multiple MN interfaces. The MN can connect to multiple networks using multiple MN interfaces, receiving care-of addresses (CoA) at each network. The MN can establish multiple connections to the CN specifying, to the HA, a different 5-tuple (or n-tuple) for each connection. The different 5-tuple can include a different port number related to a home address assigned by the HA. Also, bindings at the HA can be updated to associate the different 5-tuple with a CoA of one of the multiple MN interfaces. In this regard, the HA can route packets to the MN from the CN based at least in part on determining the HoA port number in the packet associated with the CoA of an MN interface.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 248,232, filed October 2, 2009, entitled "METHODS ANDAPPARATUS FOR MULTIPATH TCP RESOURCE POOLING," which is assigned to the assignee of this application , it is expressly incorporated herein by reference. technical field [0003] In general terms, the following description relates to wireless communications and, in particular, to multipath communications at a mobile node interface. Background technique [0004] Wireless communication systems are widely used to provide various types of communication content, such as voice, data, and so on. A typical wireless communication system may be a multiple-access system that supports communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, . . . ). Examples of such multiple-access systems may include Code Division Multiple Access (CDMA) systems, Time Divisi...
