Abstract: An anchoring network device of a telecommunications network can receive a first initiation request of a communication session and determine a second request indicating a different media capability than the first request. A network gateway can modify packets of the session, e.g., by transcoding between the capabilities. In some examples, the anchoring device can determine that a codec list of the initiation request corresponds to a rewrite rule. The device can apply the rewrite rule to the request to provide a second request listing a second, different codec. In some examples, the anchoring device can determine if there is a common media capability between the first initiation request and a predetermined exclusion list. If not, the second request can include at least one capability not in the first request, e.g., an Enhanced Voice Services (EVS) Channel-Aware-mode (ChAw) codec.

Abstract: Various embodiments provide methods for Internet Protocol (IP) packet handling. Various embodiments may enable downlink (DL) data prioritization of IP packets for time-sensitive applications, for example by using differentiated services code point (DSCP) indications or type-of-service (TOS) indications in headers of the IP packets to distinguish prioritized IP packets from non-prioritized IP packets.

Various embodiments may further enable uplink (UL) data prioritization of IP packets.
