Abstract: A method, computer-readable media and system for providing Random Access Channel (RACH) response preamble prioritization are presented. In one embodiment a method includes receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups; providing, by the PPE, an ordered prioritized list of the detected preambles; and forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list.

Abstract: A method, computer readable media and a system for determining a Voice over LTE (VoLTE) codec is presented. In one embodiment a method includes discovering a packet header size used in a session using a Silence Insertion Descriptor (SID); inspecting downlink packet sizes coming into a receive buffer; determining when three consecutive packet sizes are greater than zero, then setting a first factor, a second factor, and a third factor equal to zero; calculating a header size; and determining a voice encoding codec by subtracting a header overhead value from the packet size.

Abstract: A method is disclosed for enhancing downlink link adaptation (DLLA) for spectral efficiency maximization, comprising: providing an outer loop link adaptation (OLLA) routine with a first path for a first transmission mode and a second path for a second transmission mode; modifying, upon receiving a retransmit message for a first transmission with the first transmission mode, a first offset coefficient; modifying, upon receiving a second retransmit message for a second transmission with the second transmission mode, a second offset coefficient; and calculating a modulation and coding scheme (MCS) offset for the first transmission based on the first offset coefficient.

Abstract: Systems, methods and computer software are disclosed for providing Voice over Long-Term Evolution (VoLTE) Packet Data Conversion Protocol (PDCP) protection. In one embodiment a method is disclosed, comprising: connecting a User Equipment (UE) Radio Resource Control (RRC); providing a VoLTE call; determining, when the VoLTE call has ended, if unused bearer values for a current key are used; and when unused bearer values for a current key are unused, allocating new bearer value for a next VoLTE call.

Abstract: A method, system and computer readable medium for providing access network bit rate recommendation for Voice over Long Term Evolution (VoLTE) Coder Decoder (CODEC) change using dynamic VoLTE allocation is presented. In one embodiment a method includes determining, by an eNodeB, if Transmit Time Intervals (TTI) bundling is configured for a User Equipment (UE); and when TTI bundling is not configured, then sending an Access Network Bitrate Recommendation (ANBR) Medium Access Control (MAC) SE for VoLTE CODEC decrease.

Abstract: A method and system for for providing Circuit Switch Fall Back (CSFB) with Radio Access Network (RAN) Information Management (RIM) without network support is presented. In one embodiment, a method includes receiving, by a coordinating server, direct information transfer System Information (SI) messages with RIM Packet Data Unit (PDU) from an eNodeB; sending, by the coordinating server, a RAN-information-request message to a relevant cell, using the routing information in the RIM PDU; collecting and replaying by the cell the SI needed for CFSB to the coordinating server; storing, by the coordinating server, the latest SI information per cell; and replaying, by the coordinating server, the eNodeB with the stored SI information using a MME direct information transfer S1 message.

Abstract: Methods are disclosed for an adaptive Transmit Time Interval (TTI) Bundling Configuration using a measurement gap. In one embodiment the method includes scheduling allocation of a TTI bundle wherein part of the TTI bundle overlaps a measurement gap; transmitting, by a User Equipment (UE), only a part of the scheduled TTI bundle; and scheduling other UEs to use the resources not used by the scheduled TTI bundle.
