Abstract: The described technology is generally directed towards selecting, by user equipment, a selected maximum transmission unit (MTU) packet size for wireless data transfer based on radio signal conditions. In one aspect, reference signal received power (RSRP) and reference signal received quality (RSRQ) are used to select the MTU packet size, e.g., by using RSRP and RSRQ as indices to a lookup table of predetermined MTU packet sizes, such as previously determined by field testing. In general, smaller MTU packet sizes are used with poorer quality radio signal conditions. The selected MTU packet size may be increased or decreased based on actual performance data and/or based on changed radio signal conditions, such as for a subsequent data transfer session. The user equipment may comprise a Cat-M device that transfers data related to Machine-Type Communications (MTC)/Machine to Machine (M2M) communications.

Abstract: Disclosed are techniques for routing messages from a message delivery network (MDN) to one of a plurality of end user carriers, wherein there are a plurality of message routes capable of servicing each end user carrier. An MDN may receive a message from a sending message service provider. The MDN may identify a destination end user carrier servicing the end user device for the message. The MDN may produce a rank ordered list of message routes from the MDN to the destination end user carrier by solving a linear constrained optimization model configured to converge upon an optimized ranking of message routes from the MDN to the plurality of end user carriers. The MDN may then attach the rank ordered list of message routes to the message before forwarding the message to a gateway within the MDN. The gateway may then initially attempt delivery of the message using the highest ranked message route from the rank ordered list of message routes.
