3GPP44.060General Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 17TS

The Estimated Session Duration gives an estimation of the (remaining) duration for the MBMS session. The initial value is derived from the payload in the MBMS Session Duration IE (see 3GPP TS 48.018), rounded up to the next higher value that can be signalled with the coding provided in Table 12.44.1. Any subsequent value for the remaining duration of the MBMS session is derived from the initial value, unless an up-to-date value is available in the MBMS Session Duration IE.
