For the purposes of the present document, the terms and definitions given in TR 21.905
and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905
Aggregate Maximum Bit Rate:
The maximum bit rate that limits the aggregate bit rate of a set of non-GBR bearers of a UE. Definition derived from TS 23.401
The label (E-UTRAN only): indicates this subclause or paragraph applies only if E-UTRAN is used as current radio access network.
An EMM context is established in the UE and the MME when an attach procedure is successfully completed.
A UE is in EMM-CONNECTED mode when a NAS signalling connection between UE and network is established. The term EMM-CONNECTED mode used in the present document corresponds to the term ECM-CONNECTED state used in TS 23.401
Evolved packet core network:
A UE is in EMM-IDLE mode when no NAS signalling connection between UE and network exists. The term EMM-IDLE mode used in the present document corresponds to the term ECM-IDLE state used in TS 23.401
the successor to the 3GPP Release 7 packet-switched core network, developped by 3GPP within the framework of the 3GPP System Architecture Evolution (SAE).
Evolved packet system:
The evolved packet system (EPS) or evolved 3GPP packet-switched domain consists of the evolved packet core network and the evolved universal terrestrial radio access network. Definition derived from TS 23.401
An EPS bearer that is associated with uplink packet filters in the UE and downlink packet filters in the PDN GW where the filters only match certain packets. Definition derived from TS 23.401
An EPS bearer that is used associated with "match all" uplink and downlink packet filters in the UE and the PDN GW, respectively. Definition derived from TS 23.401
Initial NAS message:
An EPS bearer that uses dedicated network resources related to a Guaranteed Bit Rate (GBR) value, which are permanently allocated at EPS bearer establishment/modification. Definition derived from TS 23.401
A NAS message is considered as an initial NAS message, if this NAS message can trigger the establishment of a NAS signalling connection. For instance, the ATTACH REQUEST message is an initial NAS message.
Last Visited Registered TAI:
A label is a scalar that is used as a reference to node-specific parameters that control bearer level packet forwarding treatment that have been pre-configured by the operator owning the node. Definition derived from TS 23.401
A TAI which is contained in the TAI list that the UE registered to the network and which identifies the tracking area last visited by the UE.
Linked Bearer Identity:
This identity indicates to which default bearer the additional bearer resource is linked.
An area containing tracking areas served by an MME.
NAS signalling connection:
is a peer to peer S1 mode connection between UE and MME. A NAS signalling connection consists of the concatenation of an RRC connection via the "LTE-Uu" interface and an S1AP connection via the S1 interface. The UE considers the NAS signalling connection established when the RRC connection has been established successfully. The UE considers the NAS signalling connection released when the RRC connection has been released.
Non-access stratum protocols:
The protocols between UE and MSC or SGSN that are not terminated in the UTRAN, and the protocols between UE and MME that are not terminated in the E-UTRAN. Definition derived from TS 21.905
An EPS bearer that uses network resources that are not related to a Guaranteed Bit Rate (GBR) value. Definition derived from TS 23.401
an IP address assigned to the UE by the Packet Data Network Gateway (PDN GW).
Procedure Transaction Identity:
An identity which is dynamically allocated by the UE for the UE requested bearer resource activation, modification and deactivation procedures. The procedure transaction identity is released when the procedure is completed.
The label (S1 mode only):
indicates this subclause or paragraph applies only to a system which operates in S1 mode, i.e. with a functional division that is in accordance with the use of an S1 interface between the radio access network and the core network. In a multi-access system this case is determined by the current serving radio access network.
A list of TAIs that identify the tracking areas that the UE can enter without performing a tracking area update procedure.
For the purposes of the present document, the following terms and definitions given in TS 23.401
