Section: 4.2.5 Behaviour in state GMM-REGISTERED
Content: The state GMM-REGISTERED is entered when: - a GMM context is established, i.e. the MS is IMSI attached for GPRS services only or for GPRS and non-GPRS services. The specific behaviour of the MS in state GMM-REGISTERED is described in subclause 4.2.5.1. The primary substate when entering the state GMM-REGISTERED is always NORMAL-SERVICE. It should be noted that transitions between the various substates of GMM-REGISTERED are caused by (e.g.): - cell selection/reselection (see also 3GPP TS 43.022[ None ]  [82] and 3GPP TS 25.304[ None ]  [98]); - change of RA; - loss/regain of coverage. How various GMM procedures affect the GMM-REGISTERED substates is described in the detailed description of the procedures in subclause 4.7.
