In one embodiment, a method of operation of a network node in a cellular communications network is provided. The method includes determining a number of MBMS subframes for an MBMS allocation period. The method also includes, for each MBMS subframe of the number of MBMS subframes, assigning a frame number and a subframe number for the MBMS subframe such that a probability of a VoIP packet transmission during the MBMS subframe is mitigated. By mitigating the probability that a VoIP packet transmission occurs during a scheduled MBMS subframe, a VoIP user equipment (UE) may miss fewer packets and/or experience reduced battery drain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for coexistence of MBMS and VoIP services","description":"Systems and methods for coexistence of Multimedia Broadcast Multicast Services (MBMS) and Voice over Internet Protocol (VoIP) services are disclosed.
