勢。

3GPP CT Plenary

3GPP CT的主要工作是研究與制定與核心網路（3GPP Core Network）相關的標

準，而現在目標就是依據電信營運商的需求與策略，配合 LTE-Advanced系統規

格需求，規劃與制定核心網路相關的學習議題與工作議題，致於學習議題與工作

議題的詳細技術內容則是在 3GPP CT子工作群組加以討論與制定。本研發團隊

為了掌握 3GPP核心網路的現況與未來發展，為未來規劃參與 3GPP核心網路之

標準制定預作準備，期望能夠充分掌握目前會場現況與未來趨勢。目前在會場上

除了討論與修正 Release 9 以前版本的相關議題，包含 IMS 等，這次也會討論

Release 10與 Release 11相關議題如何進行。目前關注焦點放在 Home eNodeB與

MTC方面相關的議題，包含安全性與移動性等。

六、心得及建議

本 ITRI計畫研發團隊與 CHTTL研發團隊指派王瑞堂與邱哲盛參加這次在

韓國首爾（Seoul）的 3GPP RAN#48 Plenary Meeting，3GPP CT#48 Plenary

Meeting 與 3GPP SA#48 Plenary Meeting，一連串的會議由 3GPP RAN#48

Plenary Meeting（7/1~4）先開始，接著隔天是 3GPP CT#47 Plenary Meeting

（7/2~4），隔週則是 SA Plenary Meeting（7/7~10）。在 RAN Plenary討論方面，

關注的焦點放在 Multi-standard radio (MSR)與 Signalling and procedure for

in-device coexistence interference avoidance方面，而在 CT Plenary與 SA Plenary

則是關注在 Home eNodeB與MTC方面相關的議題，包含安全性與移動性等。

也唯有在 Plenary的討論，才能最接近營運商與設備製造商的核心，也才能知

道他們的最根本的需求是甚麼。

1 3GPP RAN Plenary

會議摘要

1.1 此次會議由 TTA (Telecommunications Technology Association)主辦，主

席為 Takehiro Nakamura (NTT docomo)，三位副主席分別為Marc Grant

(AT&T)、Han van Bussel (Deutsche Telekom)和 Hai Tang (China Mobile)。

1.2 此次會議共有 128人與會，技術提案共有 287篇。

1.3 重要決議：

1.3.1 Rel-10 WI Latency reductions for LTE

1.3.1.1由於 Control Plane延遲減少的效益必須付出相當的複雜度，

此工作項目將暫時停止直到 2010年 12月。

1.3.2 Rel-10標準工作之優先順序設定

1.3.2.1用以符合 ITU-R需求之工作項目(Work Item, WI)具有高優順

in-device coexistence

TL參與提案摘要

此次會議 TL共參與兩件技術提案，分別為 RP-100689及 RP-100671，摘要

如下：

1.5 “Multi-standard radio Base Station RF requirements for non-contiguous

spectrum deployments” (RP-100689)

1.5.1 此篇技術提案為 Rel-10 新工作項目(WI)，由 Vodafone領銜提案，

其他參與提案公司有 Alcatel-Lucent、Chungwa Telecom、Deutsche

Telekom、Ericsson、Huawei、NSN、Orange、Telefónica 及 ZTE，

且獲得大會通過。

1.5.2 工作目標

針對Multi-standard radio (MSR)基地台規格訂定 RF需求標準，使

得

1.5.2.1在具有多重空中介面技術(multi-RAT)佈建時，能共用相同 RF

元件；

1.5.2.2可應用於同一頻段多個非連續(non-contiguous)頻譜之情況。

1.5.3 應用情境

例如 GSM頻段(e.g. 900 MHz與 1800MHz)在進行 Re-farming時，

可能會出現GSM和LTE等兩種空中介面技術共同存在於同一基地

台，並應用同一組 RF單元，而且 GSM及 LTE是非連續頻譜。

1.5.4 主要負責工作組：RAN WG4

1.6 “Signalling and procedure for in-device coexistence interference

avoidance” (RP-100671)

1.6.1 此篇技術提案為 Rel-10新研究項目(SI)，由 CMCC領銜提案，其他

參與提案公司有 CATT、CATR、ZTE、Ericsson、ST-Ericsson、

Qualcomm、Clearwire、Sprint、NII Holdings、Mediatek、Huawei、

Deutsche Telekom、Samsung、Nokia、Nokia Siemens Networks、

Motorola、LG Electronics、Alcatel-Lucent、CHTTL及 Verizon，且

獲得大會通過。

1.6.2 研究目標

從 signaling 與 procedure 的觀點，研究適合的機制用以避免同一

device中之共存干擾(coexistence interference)。

1.6.3 應用實例

1.6.3.1 LTE與 ISM (e.g. Bluetooth、WLAN)同一 device之共存干擾

同時具有 LTE與WLAN時，若 LTE工作頻段位於 2.3GHz (e.g.

26

中國可能採用之 TD-LTE 頻段)，而 WLAN 模組於 2.4 ISM

band，則 LTE與WLAN於同一 device會有共存干擾。

1.6.3.2 LTE與 GPS同一 device之共存干擾

由於 GPS頻段位於 1.5 GHz，若 LTE工作頻段亦位於 1.5 GHz

(e.g. 日本之 LTE FDD頻段)，則 LTE與 GPS於同一 device會

有共存干擾。

1.6.4 主要負責工作組：RAN WG2

CT CR(change requests) by 3GPP release

經過了幾次小組會期的討論，使用下圖表示到目前為止，3GPP各個版本

的CR個數。這個指標表示目前Release 8之前的版本變少，技術相對應成

熟，沒有甚麼問題需要改變。而目前正在積極討論Release 9，表示目前

營運商與設備製造商在實作過程中所發現到的問題之後，回報給3GPP

標準組織，也就是說，目前大家正在積極部屬與實作Release 9的版本。

相對之下，Release 10現在是比較少人去做些改變的。

Figure: CT CRs by 3GPP

Release 10 in CT

Rel-10 work is speeding up

12 new and 2 revised Rel-10 work items were approved

5 – 10 % of approved CRs are on Rel-10

CT WGs commented on parallel work in CT and SA groups

In stable releases parallel work is efficient way to speed up the

work

If the release is not yet very stable, then parallel work wastes effort

due to re-work if requirements change

The delegations should consider any Rel-10 parallel work

carefully

CRs were approved against these work items:

IP-SM-GW enhancements for CPM-SMS interworking

(IMS_SC_eIDT)

IMS protocol improvements for Rel-10 (IMSProtoc4)

Call Completion on Not Logged-in (CCNL)

Improvements on IMS Network to Network Interface (II-NNI2)

AT commands for IMS configuration (AT_IMS)

TEI-10

Hot topic in CT

以下列出目前在CT討論比較熱烈的議題及討論重點。

ITU-T has requested 3GPP OP input to Q.1741.7

This corresponds to 3GPP Rel-9

TSG CT recommends March 2010 baseline specification set

That baseline aligns with TSG RAN ITU-T M.1457 list

Specification list has already been created by MCC

TSG CT sent LS SP-100392 to TSG SA on this

The LS contains proposed outgoing LS to OPs and PCG for SA

endorsement

Specification list is attached to the LS

TSG SA is expected to review and endorse the LS to 3GPP OPs and

PCG that is contained in SP-100392

TSG CT could not agree on the interpretation of 23.292 requirements

on the interaction of I1 and Gm interface

Set of CT1 WG agreed CRs were reviewed but not agreed

28

The postponed CRs were considered technically correct, but the I1

vs. Gm use case could not be agreed

TSG CT cannot proceed in I1 work without clarification of stage 2

requirement

LS SP-100393 was sent to SA

TSG SA is requested to allow the work to continue as part of Rel-9

TSG SA WG2 is requested to clarify the requirements in 23.292

Ideally this matter should be addressed before SA2 #80 which is

too late for CT1 to complete the stage 3 work by TSG CT #49

ETSI EMTEL is working on draft ETS 102 900 on EU-Alert

Currently the draft ETS TS is in email approval

2 weeks email approval period started on the 28th May

3GPP TS 23.041 already contains Public Warning System (PWS)

PWS is extendable

ETWS was added in Rel-8

CMAS was added in Rel-9

Radio interface Message Identifiers corresponding to alert

categories are critical resource that must be globally unique to

serve roaming users

Rel-9 version of 3GPP TS 23.041 has been published as ETS 123

041

Draft ETS 102 900 specifies normatively EU alert categories

The proposed ETS 102 900 is in conflict with ETS 123 041

In LS SP-100394 TSG CT warns against duplication of MIs that are

already specified in 3GPP TS 23.041

ETSI SCP reference update for core specifications is now completed

OMA BCAST requested in their LS reversing of this work or delaying

of it until Rel-9

TSG CT replied to OMA BCAST group in CP-100405 with a

recommendation to reference directly to ETSI SCP specifications

if also non-3GPP smart card functionality is required

With exception of test case specifications, the (3GPP part of the) work

is now completed

Open item from TSGs #47

UE fallback procedure is needed for very rare case when

The UE is in limited service state AND

UE is camping on shared network cell AND

some PLMNs available via shared network cell support

29

emergency calls but the others do not AND

The UE happens to pick a PLMN that does not support

emergency calls

Upon ATTACH REJECT the UE shall do one of the following

Fallback to other domain of the selected PLMN

Select another PLMN

If neither of the above is applicable or has been tried already,

take implementation specific actions

The work is now completed

DCN number 100380 (How to proceed with NIMTC security discussions)

from China Mobile

Items for early considerations

Comments from Samsung (may not be much useful for SA3 to start this

now except for the part in SA2 where there is some initial thinking

about MTC server and device communication over PLMN. for this SA3

can think about security but not for other scenarios).

Chair said there seems to be no problem with SA3 starting the work,

may be exploratory work at the moment but may not go in Rel 10.

SA3 can proceed but needs coordination (to be included in the Liason

report).

those OSA documents (AP 47/3).(Open)

SA2 meeting report

e-meeting in July

Slide 14; some features will not be handled by Rel 10 (split some

functions and take them during Rel 11 and take only doable in Rel 10)

For LIPA depending on progress they may consider taking entire work

as part of Rel 11 (depending on agreement or not)

32

also may include "time controlled" feature, along with overload control,

etc

Machine-Type Communications (NIMTC)

SA2 work was focused on essential generic functions based on

guidance from SA#47

Overload Control, Identifiers, Addressing & Subscription Control

Some work was progressed on MTC Low Mobility, MTC Time

Control & MTC Monitoring

Further near-term efforts expected to focus on identifying small

normative Rel-10 additions providing tools for operators to cope

with overload and subscription control to support MTC features in

the future.

The E-meeting in July is expected to "freeze" the potential

solution space for Rel-10.

Decisions (and possible SA2 normative work) on these additions

will be complete by September.

Aspects requiring substantial normative stage-2 effort are not

realistic to be completed within Rel-10.

SIPTO (Selected IP Traffic Offload) for macro networks

CRs are brought in for approval implementing the agreements

reached in February

23.401 and 23.060 CRs on full-blown stage-2 specification of the

local-GW-based solution

1. This applies both to UTRAN and eUTRAN

2. Discussions still ongoing on offload-optimized GGSN

selection from a GERAN cell

23.060 CR that describes necessary normative and informative

additions to allow offload at the Iu interface (so called TOF-based

solution)

1. This applies only to UTRAN

2. Full completion expected by September

LIPA

Concept level conclusions reached on the way forward,

architecture baseline selected

This baseline provides basis for both co-located and standalone

L-GW architectures, as well as mobility aspects

List of normative impacts for co-located L-GW scenario have been

identified

33

Further study is needed on additional impacts for supporting the

standalone L-GW configuration

Full normative support for both co-located and standalone L-GW

architectures as well as mobility aspects are unlikely to be fully

complete by September

Proponents are expected to work on a phased approach whereby

these are split across Rel-10 and Rel-11

If a phased approach does not work, LIPA in its entirety would

need to be moved to Rel-11

SA3 Report

Relay node security (on slide number 18) may be available for Rel 11,

some relation with RAN (rel 10)

Extended identity management, TR number 33.924

SA WG3 has received LSs from TISPAN, OMA and from ATIS (all

attached), which enquire about Single Sign On in different and wider

contexts than currently specified by SA WG3. In that context a proposal

for a study item was presented (S3-100655) to study how Single

Sign-On (SSO) to applications could be provided for those Common

IMS users that use an authentication method other than IMS AKA and

may not have a USIM or ISIM. Such a SSO feature is currently only

specified for users using AKA in the form of the General Bootstrapping

Architecture (GBA, cf. TS 33.220) and the integration of GBA with

OpenID, cf. TR 33.924, or the Liberty Alliance framework, cf.

TR 33.980. During the discussion several issues were raised
