20120284385 | METHOD AND APPARATUS FOR MANAGEMENT OF NETWORK COMMUNICATIONS - A method and apparatus for maintaining a communication link through a NAT or other boundary device. Keep-alive messages (keep-alives) are transmitted and received by the boundary device to maintain the link therethrough.

However, the keep-alive is inhibited from traversing the predetermined portion. This may be accomplished by one or more of: spoofing the origin of the keep-alive such that it only appears to have traversed the predetermined portion; and causing the keep-alive to be discarded before traversal of the predetermined portion. Discard may be facilitated by configuration of the TTL field of the keep-alive or by use of a filtering device. | 11-08-2012 |

Protocol selection and/or turning the interworking function on/off can be performed dynamically based on efficiency criteria. The IWF may intercept packets before traversal of the wireless link, and may optionally reside in the wireless terminals. | 01-30-2014 |

For example, the eNB may schedule transmission of the associated RAR on a restricted set of PRBs which is predictable and accessible to said LCTEs, to accommodate LCTE reception limitations. The subset of PRACH preambles can be adjusted in size in order to control system performance. The subset may include one or more preambles for exclusive use by LCTEs and/or preambles for non-exclusive use by LCTEs. | 03-26-2015 |
