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 establish context 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 decompressor supports 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.

Claims20

Dependent claims

A user equipment device (UE), comprising:

at least one antenna for performing wireless communication;
at least one radio coupled to the at least one antenna, wherein the at least one radio is configured to perform cellular communication with a base station;
one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform wireless communications using the at least one antenna;
wherein the one or more processors are configured as a data compressor, wherein the data compressor is configured to:
determine, based on first information comprised in headers of a stream of data packets, 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;
establish context with a corresponding decompressor, wherein when the context indicates that the corresponding decompressor supports decompression of TCP data packets with MPTCP option enabled, the data compressor is further configured to:
perform RObust Header Compression (ROHC) on the stream of data packets, thereby generating a chain of compressed data packets, wherein, in a first mode of compression, the MPTCP option is not compressed, wherein in a second mode of compression, the MPTCP option is compressed;
and
transmit the chain of compressed data packets to the corresponding decompressor.
