Abstract
Solutions for providing best effort service for voice calls (including video calls) using a non-guaranteed bit rate (GBR) bearer include: receiving, at a proxy node (e.g., a proxy-call session control function (P-CSCF)), a request to set up a voice session for a UE; requesting, by the proxy node, a policy node (e.g., a policy and charging rules function (PCRF) or a policy control function (PCF)) to set up a GBR data pipe (e.g., a dedicated bearer, a quality of service (QoS) class identifier (QCI) 1 bearer, or a fifth generation (5G) QoS identifier (5QI) 1 bearer); based at least on an error condition (e.g., a timeout or error message), instructing, by the proxy node, the UE to set up the voice session using an existing non-GBR data pipe (e.g., a default bearer, a QCI-5 bearer, or a 5QI-5 bearer).
