1 Scope

当前这篇文档是EPS系统总UE和MME之间移动性管理和会话管理协议相关的过程描述。这些协议都属于NAS层。

EMM协议为使用E-UTRAN的UE提供了移动控制过程。同样也为NAS协议提供安全控制。

ESM协议提供了处理EPS承载上下文的过程。和ASA层提供的承载控制一起，ESM协议也用作用户面承载的控制。

对于NAS协议，本篇文档也描述了在E-UTRAN和其他3GPP或者non-3GPP之间的系统间移动性过程：

对于E-UTRAN和GERAN或者UTRAN系统间移动性，包含了本文档中叙述的NAS协议使用的参数/过程和3GPP TS 24.008 [13]中描述的NAS协议之间的映射规则。

对于E-UTRAN和non-3GPP接入网络，包含了连接PDN网关维持IP连接的NAS过程和当双栈手机IPv6(see 3GPP TS 24.303 [14]) 或者 MIPv4 (see 3GPP TS 24.304 [15])使用移动性管理需要UE提供参数的NAS过程。

当前文档是对EPS中的UE和MME都是有效的。

当前文档中EPS中的中继节点(see 3GPP TS 23.401 [10])也是有效的。

Linked Bearer Identity: This identity indicates to which default bearer the additional bearer resource is linked.

LIPA PDN connection: A PDN connection, for which the default EPS bearer context or default PDP context was activated with an APN authorized to use LIPA. The network authorizes an APN for using LIPA based on the subscription profile (see 3GPP TS 29.272 [16C]) and subsequently the network considers this PDN connection a LIPA PDN connection.

Lower layer failure: A failure reported by the AS to the NAS that cannot be corrected on AS level. When the AS indicates a lower layer failure to NAS, the NAS signalling connection is not available.

NAS signalling connection: 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. Additionally, for the purpose of optimized handover or idle mode mobility from cdma2000® HRPD access to E UTRAN (see 3GPP TS 23.402 [11]), the NAS signalling connection can consist of a concatenation of an S101 AP connection and a signalling tunnel over a cdma2000® HRPD access network.

NOTE 1: cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA).

NAS signalling connection recovery: A mechanism initiated by the NAS to restore the NAS signalling connection on indication of “RRC connection failure” by the lower layers.

Native GUTI: A GUTI previously allocated by an MME. Definition derived from 3GPP TS 23.401 [10].

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 3GPP TR 21.905 [1].

Non-emergency EPS bearer context: Any EPS bearer context which is not an emergency EPS bearer context.

Non-EPS services: Services provided by CS domain. Within the context of this specification, non-EPS services is used as a synonym for non-GPRS services in 3GPP TS 24.008 [13]. A UE which camps on E-UTRAN can attach to both EPS services and non-EPS services.

Non-GBR bearer: An EPS bearer that uses network resources that are not related to a guaranteed bit rate (GBR) value. Definition derived from 3GPP TS 23.401 [10].

NOTE 2: An example of a persistent EPS bearer context is a non-emergency EPS bearer context with QCI = 1 where there is a radio bearer associated with that context.

Procedure Transaction Identity: An identity which is dynamically allocated by the UE for the UE requested ESM procedures. The procedure transaction identity is released when the procedure is completed.

RAT-related TMSI: When the UE is camping on an E-UTRAN cell, the RAT-related TMSI is the GUTI; when it is camping on a GERAN or UTRAN cell, the RAT-related TMSI is the P-TMSI.

Registered PLMN: The PLMN on which the UE is registered. The identity of the registered PLMN is provided to the UE within the GUTI.

Relay node: A network element in the E-UTRAN, wirelessly connected to an eNode B and providing relaying function to UEs served by the E-UTRAN. Definition derived from 3GPP TS 23.401 [10].

The label (S1 mode only) indicates that 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.

S101 mode: Applies to a system that operates with a functional division that is in accordance with the use of an S101 interface. For the definition of the S101 reference point, see 3GPP TS 23.402 [11].

SIPTO at the local network PDN connection: A PDN connection, for which the default EPS bearer context or default PDP context was activated with an APN authorized to use SIPTO at the local network and it was activated such that the traffic of the PDN connection will be using an L-GW. The network authorizes an APN for using SIPTO at the local network based on the subscription profile (see 3GPP TS 29.272 [16C]) and subsequently the network considers this PDN connection a SIPTO at the local network PDN connection.

SIPTO at the local network PDN connection with a collocated L-GW: A SIPTO at the local network PDN connection which is established to a L-GW function collocated with the (H)(e)NodeB. The core-network entity (i.e. the MME or the SGSN) can be aware of whether the SIPTO at the local network PDN connection with a collocated L-GW is used when the PDN connection is established.

SIPTO at the local network PDN connection with a stand-alone GW: A SIPTO at the local network PDN connection which is established to a stand-alone GW (with collocated L-GW and S-GW). The core-network entity (i.e. the MME or the SGSN) can be aware of whether the SIPTO at the local network PDN connection with a stand-alone GW is used when the PDN connection is established.

“SMS only”: A subset of services which includes only Short Message Service. A UE camping on E-UTRAN can attach to both EPS services and “SMS only”.

Subscribed APN based congestion control: Congestion control in mobility management where the network can reject attach requests from UEs with a certain APN in the subscription.

TAI list: A list of TAIs that identify the tracking areas that the UE can enter without performing a tracking area updating procedure. The TAIs in a TAI list assigned by an MME to a UE pertain to the same MME area.

Traffic flow aggregate: A temporary aggregate of packet filters that are included in a UE requested bearer resource allocation procedure or a UE requested bearer resource modification procedure and that is inserted into a traffic flow template (TFT) for an EPS bearer context by the network once the UE requested bearer resource allocation procedure or UE requested bearer resource modification procedure is completed.

UE configured for dual priority: A UE which provides dual priority support is configured for NAS signalling low priority and also configured to override the NAS signalling low priority indicator (see 3GPP TS 24.368 [15A], 3GPP TS 31.102 [17]).

UE configured to use AC11 – 15 in selected PLMN: A UE configured with at least one access class in the range 11-15 on the USIM, and the access class is applicable in the selected PLMN according to 3GPP TS 22.011 [1A].

UE’s availability for voice calls in the IMS: The indication of this availability or non-availability is provided by the upper layers of the UE as specified in 3GPP TS 24.229 [13D] in the annex relevant to the IP-Connectivity Access Network in use or determined in the NAS layer, as specified in subclause 4.3.1. If availability is indicated, the UE uses the IM CN Subsystem and can terminate or originate requests for SIP sessions including an audio component with codecs suited for voice.

UE’s usage setting: This is a UE setting that indicates whether the UE has preference for voice services over data services or vice-versa. If a UE has preference for voice services, then the UE’s usage setting is “voice centric”. If a UE has preference for data services, then the UE’s usage setting is “data centric”. A UE whose setting is “data centric” may still require access to voice services. A UE whose setting is “voice centric” may still require access to data services. This definition is derived from 3GPP TS 23.221 [8A] and it applies to voice capable UEs.
