GROUPE, S2-144403: Update Solution of Group based messaging

using cell broadcast to support AESE framework

此提案根據 AESE TR23.708 中 Service Exposure Framework 所決

議的系統架構提出更新支援 group based messaging via cell

broadcasting 的系統架構,如附件圖一所示。

在更新的系統架構中,在 PLMN 中的 SCEF (service capability

exposure framework)可藉由 3GPP 網路的 Tcb 和 Sh 介面提供傳

遞 group based messaging。此外,MTC-IWF 成為 SCEF 的部分功

Page 8: 3GPP SA2 #106 Meeting 會議報告

7

能,可允許 SCEF 直接存取 Tcb 及 Sh 介面,並避免必須增加

MTC-IWF 的新功能。

此提案經過討論後通過。

GROUPE, S2-144598: Resolve FFSs in Editor's Notes for Solution

5.1.3.1

在此提案中,針對 group based messaging via cell broadcasting 方案

中的 FFS (for further study)的註解提出以下澄清:

Editor’s Note: The UE modes (idle/active CS/PS) that can detect the

group trigger/message is FFS:

- 澄清:此方案中並無預期任何 UE 的功能變更,因此接收群組

訊息時可應用的 UE 模式可以包括 idle/active, CS/PS

Editor’s Note: It is FFS what is the granularity of the group ID and

how the network allocates/reallocates one or more group IDs in

which each is associated to one 3GPP internal group identifier for a

specific group messaging service.

- 澄清:在主要議題 group identifier and addressing 中將有針對所

有 group based messaging delivery 方案提出共通的機制。因此

在此方案中不需提出專有方案

Editor’s Note: It is FFS on how to deliver group based messaging for

MTC devices in power saving mode.

Page 9: 3GPP SA2 #106 Meeting 會議報告

8

- 澄清:根據 stage 1 的 TS 22.368 規格書,clause 7.2.14.3 章節:

group based addressing 所述:Verification of receipt of a broadcast

message is not necessary。因此,此提案提出在 group based

messaging delivery 的方案中,並無必要保證廣播的訊息被成功

接收。此外,要系統區分以下可能造成失敗無法接收群組訊息

的成因也是困難的,例如:UE在 limited state,啟動 power saving

mode 模式,或遭受不好的接收訊號條件等。因此,此提案提

出由網路策略來安排群組訊息的重傳機制。

- 在會議中與會代表要求增加以下註明:當 UE 在 power saving

mode 時可能在重傳的規劃中依然無法接收群組訊息。

Editor’s Note: FFS whether the message ID space that can be used for

group messaging based on cell broadcast can be divided between the

network-sharing partners without restricting the usability of the

approach in shared networks.

- 澄清:提出在 Rel-13 方案中不支援共享網路中傳遞群組訊息。

Editor’s Note: roaming considerations for both inbound and outbound

roaming are FFS.

- 澄清:漫遊 UE 接收細胞廣播訊息的方式與漫遊 UE 接收針對

群組發送的細胞廣播訊息,兩者並無差別。

Editor’s Note: How to control that only UEs belonging to a certain

group read respective group messages is FFS.

Page 10: 3GPP SA2 #106 Meeting 會議報告

9

- 澄清:針對安全性議題,將需要 SA3 工作群組提出評估與建

議,因此,提議可發送聯絡函通知 SA3 開始評估此方案的相關

安全議題。

Editor’s Note: The type of controlled access is FFS. Examples

include: network provided dispersion parameters to be used by each

member of the MTC group, or a hashing algorithm based on e.g.,

IMEI that the UE uses to offset access time.

- 澄清:此機制用來控制分散回覆系統訊息的時間,這是避免接

收到群組廣播訊息的 UEs 同時回覆訊息造成系統壅塞。此機制

的設計將可使用 UE 的 IMEI 當做產生隨機回覆時間的依據。

此部分屬於對 UE 的影響,因此改納入方案評估章節。

此提案經過討論後通過。

ProSe, S2-144576: 23.303 CR0140: Correction of steps in Match

Report

此提案由 Qualcomm, HTC 共同提出

更正理由:在 match report 程序當中,Monitoring UE 的 Home

ProSe Function 會根據在 monitoring request 中得到的 Announcing

UE 所註冊的 VPLMN ID 資訊傳送包含 Charging 資料的訊息給

VPLMN 中的 ProSe Function,然而,在兩個程序中間,UE 可能

會因移動而改變了其註冊的 VPLMN,因此 ProSe Function 將無法

傳送訊息給 Announcing UE 真正所在 VPLMN 的 ProSe Function。

Page 11: 3GPP SA2 #106 Meeting 會議報告

10

更正提案:因為 Monitoring UE 將在 match report 程序中提供

Monitored PLMN ID,在 monitoring UE 偵測到 ProSe Application

Code 時,此 Monitored PLMN ID 資訊將可提供 Announcing UE 真

正所在 VPLMN 的資訊,因此訊息將不會傳送至錯誤的 VPLMN

ProSe Function。

此提案經過討論後通過。

ProSe, S2-144176: 23.303 CR0144: Clarification on the EPLMN issue in

ProSe Direct Discovery

此篇提案由 HTC 提出

更正理由:因為 UE 在移動進入所設定的一個 Tracking Area 時,

當此 Tracking Area連結的 PLMN屬於 Equivalent PLMN也不同於

該UE所註冊的 PLMN時,此UE並不會發送Tracking Area Update

Request 訊息給網路重新註冊以更新 HSS 中的註冊 PLMN 資訊。

因此,在服務授權改變時,HSS 無法根據正確的註冊 PLMN 資訊

發送更新訊息給 UE 註冊的 MME 做出改變。

更正提案:要求 UE 在具有 Direct Discovery 的 announcing 授權

時,當發生改變 PLMN 時,將必須發送 Tracking Area Update

Request。

提案討論:在 Stage1 中 Equivalent PLMN 的設定僅根據行動管理

的考量,與服務無關,因此,並無限定 Equivalent PLMN 必須提

Page 12: 3GPP SA2 #106 Meeting 會議報告

11

供相同的服務。因此要求 UE 根據服務改變行動管理策略是不恰

當的,此外,與會公司要求以網路端方案來解決。因此,S2-144575

提出網路端方案的提案成為候選的解決方案。

此提案經過討論後被否決。

2.2 其他會議重點提案

NBIFOM 部分:

NBIFOM, S2-144465: Clarifications and resolution of open issues in

section 7.8 on control mode

此提案由以下公司共同提案簽署:Qualcomm Incorporated,

Samsung, Huawei, Hisilicon, ZTE

UE 可能會依據 ISRP 觸發 UE-initiated IFOM service;PGW 可能

依據從 PCRF 獲得的 PCC rules 觸發 NW-initiated IFOM service。

因為觸發 UE 以及 Network 的依據獨立,因此當兩者共存之時,

就有可能發生衝突。

此提案提出修正 Solution A、 Solution B 的部分文字敘述,以及

提出新的 Solution 以完成 Solution C 中留下 open issues 部分。

新的 Solution 依照 operator 是否想要透過 PCC 控制 routing ,將

Routing Rule 分成兩種:不可被更改以及可被更改。當 UE 收到

的 Routing Rule 中 “Negotiation Indication” 被設為 “forbidden”

Page 13: 3GPP SA2 #106 Meeting 會議報告

12

時,UE 不能更改這個 Routing Rule;反之亦然。

此提案經討論後通過

NBIFOM , S2-144669: Solution for Loss of WLAN Coverage

此提案由以下公司共同提案簽署:Huawei, HiSilicon, InterDigital

Communications, Samsung, ZTE, Qualcomm Incorporated, Intel

此提案提出一個解決方案,在同時擁有 WLAN 以及 3GPP 的連線

下,當UE 離開WLAN/3GPP 覆蓋範圍或是失去WLAN/3GPP 連

線時,如何維持原有的資料傳輸。當 UE 偵測到失去WLAN/3GPP

連線時,UE 透過 MME/TWAN 通知 P-GW 失去連線的 IP flows

訊息,P-GW 轉傳訊息給 PCRF 以產生新的 Routing Rule,並將

原有的在 WLAN/3GPP 上的 IP flows 全部移往 3GPP/WLAN 上。

此提案經討論後通過

NBIFOM, S2-144455: UE impacts on NBIFOM solutions

此提案由 LG Electronics 提出,討論 NBIFOM service 中

control-plane 以及 user-plane 的解決方案對原有 UE 所造成的影

響。

在 control-plane 的部分新增:UE 同時支援 UE-initiated 以及

NW-initiated 的 IFOM 步驟;UE 接受或是拒絕 NW-initiated

IFOM。

在 user-plane 的部分新增:在 UE-initiated 的情況下,UE 傳送一

Page 14: 3GPP SA2 #106 Meeting 會議報告

13

個 “redirection” 的封包;在 NW-initiated 的情況下,UE 接受一

個 “redirection” 的封包。

此提案經討論後通過

NBIFOM, S2-144466: Co-existence with ANDSF for control-plane

signaling solution

提案由以下公司共同提案簽署:LG Electronics, Qualcomm

Incorporated, Huawei, ZTE

在既有的 “與 ANDSF 共存下的 user-plane signaling 解決方案”

中,延伸提出一個新的 control-plane signaling 解決方案:UE 可

以同時使用NBIFOM solution或是 ANDSF traffic steering rules來

當作 IFOM 的規則,UE 不能違反 ANDSF 或是 network policy,

透過禁止的連線轉傳送資料。

此提案經討論後通過

NBIFOM, S2-144016: Handling open issue #2 in NBIFOM control plane

solution

此提案由 Samsung 提出,討論“Open Issue #2: Do we need

additional indication (i.e. null routing rule) as described in some of

the alternatives below to indicate to PGW not to release the

connection even when all the IP flows are moved to another access?”

在 control-plane signaling 的解決方案。

此提案指出 UE 或是 NW 可以透過修改 Routing Rule,維持

Page 15: 3GPP SA2 #106 Meeting 會議報告

14

multiple access PDN connection 其中一個 access 連線,且沒有實

際的資料在此 access 上傳輸。而實際上如何運作,雖然不在 3GPP

的規範之內,但是一些 implementation 的分針還是可以寫在 spec

裡面﹕在 Routing filter 使用 discard port (i.e., port 9);Routing

priority 改為 low。

此提案經討論後通過

2.3 SA2#106 標準會議決議重點提要

1. 根據 SA#65 的決議,3GPP 將成立 SA6 訂定應用層相關標準,並在

Rel-13 先針對 MCPTT(mission critical push to talk)工作項目為主,SA6

已於此次舊金山會議中舉行一連三天的會前會,根據目前 SA2 初步決

議的 MCPTT 系統架構,討論如何整合目前各標準工作組織 OMA,

PCPS 所現有的 PTT 架構。SA6 將於一月正式成立,與 SA2#107 同地

舉行,SA6#1 並將選出第一屆主席。

2. 此次 SA2 會議,針對 Rel-13 的工作項目有許多提案討論,並完成許多

進展,包括:MCPTT, MTC 相關工作項目(例如:Group、Monitoring、

AESE)、NB-IFOM(Network-based IP flow mobility and seamless

offload)、eWebRTC (extended WebRTC)、eCSFB(enhancement of CS

fallback)等,會議結束預期各工作項目進度成果請見 S2-144499。

Page 16: 3GPP SA2 #106 Meeting 會議報告

15

3. 目前在 SA2 通過的工作項目過多超過負載,在 SA#66 根據營運商的需

求將會討論並可能決議 Rel-13 的優先工作項目。

4. 在此會期中已經新增新的議程,可以針對 Rel-13 的規格書提出新的功

能,提案類別屬於 B 或 C,包括:23.060, 23.221, 23.251, 23.272, 23.303,

23.401, 23.468, 23.682。

5. SA2 因過多的工作項目,在有限的會議時間內許多提案未能被討論,

因此在此次會議中研議於 2016 年年初舉辦一次所謂的 electronic

meeting,經由電子郵件群組討論提案,討論結果將具有通過提案決議

的效力。

六、心得與建議

1. 目前在 SA2 有兩個可能具有 UE 影響的 Rel-13 工作項目通過,且尚未

排入議程,包括: Feasibility Study on Co-ordinated P-GW Change for

SIPTO (FS_CSIPTO)以及 New Study Item for Isolated E-UTRAN

Operation for Public Safety (IOPS),建議與會公司可以開始進行提案布

局,在工作群組開始規劃初期即能參與討論並與提案公司建立合作討

論管道。

2. 預計 2015年 3月的 SA plenary將選出新任主席,以及 2015年 4月 SA2

WG 也將選出新任主席及副主席兩席,此次選舉針對副主席人選較往

Page 17: 3GPP SA2 #106 Meeting 會議報告

16

年有更多公司宣布推出候選人參選,並以展開拉票競選活動,競爭非

常激烈。選舉時各候選人將會積極諮詢各個公司的意見並討論在雙方

有興趣發展的工作群組提出可能合作的方向與機會,因此建議各個公

司應該把握此機會好好與各個派出候選人代表的公司接觸與交流。此

外,針對投票權的維護,必須在選舉的該次會議前出席註冊連續至少

兩次會議,也是各公司必須要注意的,以避免喪失投票權。
