Systems and methods for coexistence of MBMS and VoIP services
First Claim
1. A method of operation of a network node in a cellular communications network, comprising:
- obtaining a pattern of special subframes where the special subframes in the pattern of special subframes are selected from the group consisting of Multimedia Broadcast Multicast Service, MBMS, subframes, Almost Blank Subframes, ABS, New Carrier Type, NCT, subframes, and subframes assigned for Positioning Reference Signals, PRS;
receiving a request for a Voice over Internet Protocol, VoIP, Radio Access Bearer, RAB, from a user equipment, UE; and
determining one or more discontinuous reception, DRX, parameters for the VoIP RAB based on the pattern of special subframes.

Abstract
Systems and methods for coexistence of Multimedia Broadcast Multicast Services (MBMS) and Voice over Internet Protocol (VoIP) services are disclosed. 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.
