Non-Access-Stratum (NAS) functions related to Mobile Station (MS) in idle mode

(Release 12)

1 Scope

当前文档概述了UE在idle状态下核心网协议栈所采取的任务，也就是，UE开机但是没有分配专有信道。文档也描述了相应的网络功能。只要没有分配专有信道给MS，GPRS MS会执行idle模式功能。在TRA RRC连接模式状态MS什么时候执行idle模式功能在3GPP TS 25.331 [33]中描述。在E-UTRAN中MS什么时候执行idle模式功能在3GPP TS 36.304 [43]中描述。

当前文档定义了支持3gpp和3gpp2的多模MS的PLMN选择。通常的PLMN选择逻辑覆盖了3gpp2系统的PLMN，但是当前的文档对3gpp2系统中的cdma2000信令没有任何改变。

当前的文档给出了使用CSG小区的过程，当这个功能是允许使用的时候。

这个3GPP TS概述了在idle模式下22系列技术规范的要求应该如何实现，（特别3GPP TS 22.011 [9]）。更详细的在3GPP TS 24.008 [23]中。

这个协议的第二章是idle模式处理的一般描述。第三章概述总体需求和这些需求的技术解决方案。第四章idle模式下使用的过程。这些章节之间不可避免有一些重复。

NOTE： cdma2000是TIA-USA注册的一个商标。

当前文档不考虑GERAN Iu模式。

1.1 References 参考其他的规范

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

- References are either specific (identified by date of publication, edition number, version number, etc.) or non‑specific.

- For a specific reference, subsequent revisions do not apply.

- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

1.2 Definitions and abbreviations 定义和缩略语

For the purposes of the present document, the abbreviations defined in 3GPP TR 21.905 [36] apply.

(A/Gb mode only): Indicates this clause applies only to a GSM system which operates in A/Gb mode. For multi system case this is determined by the current serving radio access network.

(Iu mode only): Indicates this clause applies only to UMTS system. For multi system case this is determined by the current serving radio access network.

Acceptable Cell: This is a cell that the MS may camp on to make emergency calls. It must satisfy criteria which are defined for A/Gb mode in 3GPP TS 43.022 [35], for Iu mode in 3GPP TS 25.304 [32], and for S1 mode in 3GPP TS 36.304 [43].

Access Technology: The access technology associated with a PLMN. The MS uses this information to determine what type of radio carrier to search for when attempting to select a specific PLMN (e.g., GSM, UTRAN, GSM COMPACT or E-UTRAN). A PLMN may support more than one access technology.

Allowable PLMN: In the case of a MS operating in MS operation mode A or B, this is a PLMN which is not in the list of “forbidden PLMNs” in the MS. In the case of a MS operating in MS operation mode C, this is a PLMN which is not in the list of “forbidden PLMNs” or in the list of “forbidden PLMNs for GPRS service” in the MS

Available PLMN: For GERAN A/Gb mode see 3GPP TS 43.022 [35]. For UTRAN see 3GPP TS 25.304 [32]. For E-UTRAN see 3GPP TS 36.304 [43]. For cdma2000® 1xRTT and cdma2000® HRPD see 3GPP2 C.S0016 [44].

Available PLMN/access technology combination: This is an available PLMN in a specific access technology.

Camped on a cell: The MS (ME if there is no SIM) has completed the cell selection/reselection process and has chosen a cell from which it plans to receive all available services. Note that the services may be limited, and that the PLMN may not be aware of the existence of the MS (ME) within the chosen cell.

Country: A country is identified by a single MCC value, with the exception that MCC values 310 through 316 identify a single country (USA) and MCC values 404 through 406 identify a single country (India).

CSG whitelist: See 3GPP TS 36.304 [43].

Current serving cell: This is the cell on which the MS is camped.

CTS MS: An MS capable of CTS services is a CTS MS.

EAB: Extended Access Barring, see 3GPP TS 22.011 [9].

EHPLMN: Any of the PLMN entries contained in the Equivalent HPLMN list.

Equivalent HPLMN list: To allow provision for multiple HPLMN codes, PLMN codes that are present within this list shall replace the HPLMN code derived from the IMSI for PLMN selection purposes. This list is stored on the USIM and is known as the EHPLMN list. The EHPLMN list may also contain the HPLMN code derived from the IMSI. If the HPLMN code derived from the IMSI is not present in the EHPLMN list then it shall be treated as a Visited PLMN for PLMN selection purposes.

Generic Access Network (GAN): See 3GPP TS 43.318 [35A].

GAN mode: See 3GPP TS 43.318 [35A].

GPRS MS: An MS capable of GPRS services is a GPRS MS.

MS operation mode: See 3GPP TS 23.060 [27].

High quality signal: The high quality signal limit is used in the PLMN selection procedure. It is defined in the appropriate AS specification: 3GPP TS 43.022 [35] for the GSM radio access technology, 3GPP TS 25.304 [32] for the UMTS radio access technology (FDD or TDD mode), 3GPP TS 36.304 [43] for the E‑UTRAN radio access technology. For 3GPP2 access technologies the high quality signal limit is defined in 3GPP2 C.S0011 [45] for cdma2000® 1xRTT and in 3GPP2 C.S0033 [46] for cdma2000® HRPD.

Home PLMN: This is a PLMN where the MCC and MNC of the PLMN identity match the MCC and MNC of the IMSI. Matching criteria are defined in Annex A.

In A/Gb mode,…: Indicates this clause applies only to a GSM system which operates in A/Gb mode. For multi system case this is determined by the current serving radio access network.

In Iu mode,…: Indicates this clause applies only to UMTS system. For multi system case this is determined by the current serving radio access network.

Localised Service Area (LSA): A localised service area consists of a cell or a number of cells. The cells constituting a LSA may not necessarily provide contiguous coverage.

Location Registration (LR): An MS which is IMSI attached to non-GPRS services only performs location registration by the Location Updating procedure. A GPRS MS which is IMSI attached to GPRS services or to GPRS and non-GPRS services performs location registration by the Routing Area Update procedure only when in a network of network operation mode I. Both location updating and routing area update procedures are performed independently by the GPRS MS when it is IMSI attached to GPRS and non-GPRS services in a network of network operation mode II (see 3GPP TS 23.060 [27]). An MS which is attached via the E-UTRAN performs location registration by the tracking area update procedure.

MS: Mobile Station. The present document makes no distinction between MS and UE.

Network Type: The network type associated with HPLMN or a PLMN on the PLMN selector (see 3GPP TS 31.102 [40]). The MS uses this information to determine what type of radio carrier to search for when attempting to select a specific PLMN. A PLMN may support more than one network type.

Registered PLMN (RPLMN): This is the PLMN on which certain LR outcomes have occurred (see table 1). In a shared network the RPLMN is the PLMN defined by the PLMN identity of the CN operator that has accepted the LR.

Registration: This is the process of camping on a cell of the PLMN and doing any necessary LRs.

Registration Area: A registration area is an area in which mobile stations may roam without a need to perform location registration. The registration area corresponds to location area (LA) for performing location updating procedure, to routing area for performing the GPRS attach or routing area update procedures, and to list of tracking areas (TAs) for performing the EPS attach or tracking area update procedure.

The PLMN to which a cell belongs (PLMN identity) is given in the system information transmitted on the BCCH (MCC + MNC part of LAI). In a shared network a cell belongs to all PLMNs given in the system information transmitted on the BCCH.

Selected PLMN: This is the PLMN that has been selected according to subclause 3.1, either manually or automatically.

Shared Network: An MS considers a cell to be part of a shared network, when multiple PLMN identities are received on the BCCH.

SIM: Subscriber Identity Module (see 3GPP TS 21.111 [38]). The present document makes no distinction between SIM and USIM.

SoLSA exclusive access: Cells on which normal camping is allowed only for MS with Localised Service Area (LSA) subscription.

Suitable Cell: This is a cell on which an MS may camp. It must satisfy criteria which are defined for GERAN A/Gb mode in 3GPP TS 43.022 [35], for UTRAN in 3GPP TS 25.304 [32] and for E-UTRAN in 3GPP TS 36.304 [43]. For 3GPP2 access technologies the criteria are defined in 3GPP2 C.S0011 [45] for cdma2000® 1xRTT and in 3GPP2 C.S0033 [46] for cdma2000® HRPD.

Steering of Roaming: A technique whereby a roaming UE is encouraged to roam to a preferred roamed-to network by the HPLMN.

Visited PLMN: This is a PLMN different from the HPLMN (if the EHPLMN list is not present or is empty) or different from an EHPLMN (if the EHPLMN list is present).
