Embodiment Construction

[0032] the term

[0033] The following is a glossary of terms used in this disclosure:

[0034] memory medium - any of various types of non-transitory memory devices or storage devices. The term "storage medium" is intended to include installation media such as CD-ROM, floppy disk or tape devices; computer system memory or random access memory such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory Such as flash memory, magnetic media such as hard drives or optical storage devices; registers or other similar types of memory elements, etc. The storage medium may also include other types of non-transitory memory, or combinations thereof. Furthermore, the memory medium may be located in a first computer system that executes the program, or may be located in a different second computer system connected to the first computer system through a network such as the Internet. In the latter case, the second computer system may provide the program instructions to ...

Abstract

Some embodiments relate to a user equipment device (UE), and associated methods for performing ROHC header compression on TCP packets with MPTCP option enabled. In some embodiments, a compressor may determine that a first portion of the stream of data packets is formatted according to the transmission control protocol (TCP) with a multipath TCP (MPTCP) option enabled. The compressor may establishcontext with a corresponding decompressor and may operate in one of three modes of compression based on the context. In some embodiments, when the context indicates that the corresponding decompressorsupports decompression of TCP data packets with MPTCP option enabled, the compressor may operate in a first or second mode of compression. In some embodiments, when the context indicates that the corresponding decompressor does not support decompression of TCP data packets with MPTCP option enabled, the compressor may operation in a third mode of compression.

Description

technical field [0001] This application relates to wireless communications, including providing techniques for ROHC header compression for MPTCP packets. Background technique [0002] The use of wireless communication systems is growing rapidly. Additionally, wireless communication technology has evolved from voice communication only to also include the transmission of data such as the Internet and multimedia content. [0003] ROHC (Robust Header Compression) is a standardization for compressing headers of various types of Internet packets such as UPD (User Datagram Protocol), RTP (Real-Time Transport Protocol), and TCP (Transmission Control Protocol) packet types ( See, eg, Internet Engineering Task Force (IETF) Request for Comments (RFC) 3095, IETF RFC 3759, IETF RFC 4815, IETF RFC 5225, and IETF RFC 6846) methods. In a typical streaming application, headers range from 40 bytes for IPv4 (Internet Protocol version 4) to 60 bytes for IPv6. ROHC compresses the header from ...
