Scope

The present document specifies the procedures used by the protocols for mobility management and session management between user Equipment(UE) and mobility management entity(MME) in the evolved packet system(EPS).These protocols belong to the non-acess stratum(NAS).The EPS mobility management(EMM) protocol defined in the present document provides procedures for the control of mobility when the user equipment (UE) is using the evolved UMTS Terrestrial radio Acess Network (E-UTRAN) The EMM protocol also provides control of security for the NAS protocols.The EPS session Management (ESM) protocol defined in the present document provides procedures for the handling of EPS bearer context.Together with the bearer control provided by the access stratum,this protocol is used for the control of user plane bearers.For both NAS protocols the present document specifies procedures for the support of inter-system mobility between E-UTRAN and other 3GPP or non-3GPP or non 3GPP TS 24.008 For inter-system mobility between E-UTRAN and GERAN or UTRAN this includes rules for a mapping between parameters and procedures used by the NAS protocols defined in the present document and the NAS protocols specified in 3GPP TS 24.008 For inter -system mobility between E-UTRAN and generic non 3GPP acess networks this includes specific NAS procedures to maintain IP connectivity to the PDN Gateway and to provide parameters needed by the UE when using mobility management based on dual stack mobile the present document is applicable to the UE and to the mobility management entity(MME) in the EPS the present document is also applicable to the relay node in the EPS(see 3GPP TS 23.401)
