Introduction The future environment will be characterised by features such as multimedia services and the convergence of 3GPP systems and the Internet. In this environment the total User Equipment used to access 3GPP services may be implemented over
21、 a number of physical devices. For example the User Equipment may include a PC or PDA with appropriate client software as well as a separate module containing radio protocols and other elements. These cases are referred to under the term UE Functionality Split or just UE Split. This report identifie
22、s scenarios and requirements for UE Functionality Split. ETSI ETSI TR 122 944 V13.0.0 (2016-01)53GPP TR 22.944 version 13.0.0 Release 131 Scope This report identifies scenarios and requirements for UEs with functionality split over multiple devices. Scenarios that are required to be supported in the
23、 standard are defined in detail. The requirements in this report should enable interoperability between user equipment components from different vendors. This report is not intended to identify all possible or permitted functionality splits. Certain splits of functionality may be prohibited for secu
24、rity or other reasons. This report does not identify all prohibited scenarios. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

One case is that all the user equipment is integrated in to a single physical device. This report deals with cases where several different components m

This illustration is only meant to introduce concepts and not imply any limitations or physical form for user equipment.

35、 in 3GPP should aim to exploit technology trends and to promote the convergence of 3GPP technologies with Internet and computing technologies. The objective of this report is to identify a scenario which is seen as being particularly important for the success of the 3GPP system. The scenario should:
36、 - correspond to likely physical scenario for available equipment - offer attractive commercial opportunities - be simple enough to allow requirements capture and technical specifications to be completed - align with other standards (e.g. Bluetooth, PC-Card) and common industry practice (e.g. major
37、operating systems) where appropriate Allowing some 3GPP related applications to be implemented on TEs separate from the MT offers advantages such as: - Ability for applications to evolve without changing hardware or firmware. This will improve service velocity. - Ability of 3GPP applications to inte
38、grate with a user“s other business, entertainment and communications tools. - Allowing 3GPP applications to take advantage of the physical characteristics of computer (e.g. large display, memory, processing power) - Ability to use hardware built into the TE (eg speaker, microphone) for input and out
39、put. - Integration of emerging wireless LAN technologies (e.g. Bluetooth, 802.11b) with 3GPP networks This will facilitate the development of applications in the TE that use 3GPP services independently of the specific 3GPP defined radio module being used. For example the application developer should
40、 not need to write different applications for 3GPP defined radio modules made by different vendors. The scenario considered is shown in Figure 1. In this case, multiple independent applications that are possibly being used by independent users employ one subscription and its information is stored in
41、 one UICC as shown in Fig. 1. The user(s) identity is possibly different from the subscribers identity. TE IUMTS/GSM/GPRSNetworkTE IIITE IIMTUICCCBIBIIBIIIFigure 2: Multiple applications and/or users with one subscriber identity. Note: The single TE associated with a single MT scenario is a special
42、case of this scenario. In this case the restriction is that only a single subscription on the UICC may be active. In this release a subscription consists of a SIM/USIM for non-IMS subscribers or a ISIM/USIM pair for IMS subscribers. Examples of where scenario 1 is useful include: - A PC or PDA conta
43、ins a 3GPP defined radio module to allow it to access 3GPP services. The module may be a (semi)permanent part of the PC or PDA (similar to an embedded modem) or a removable module such as a PC card. ETSI ETSI TR 122 944 V13.0.0 (2016-01)83GPP TR 22.944 version 13.0.0 Release 134.3 Assumptions The fo
44、llowing assumptions are made: a The transport link between the TE and MT functions of the UE is not necessarily secure. b A SIM/USIM application resident on a UICC is required to access the 3GPP system . Only a single USIM on a UICC can be active at any time (multiple USIMs can be located on a UICC)
45、. c Charging is linked to one particular USIM. d The secret key and the authentication algorithm cannot be transferred out from the USIM. e The UICC must be present during the entire duration of the call. Periodic UICC presence detection is mandatory during a call. f Requirements identified in 3 reg
46、arding the ISIM must be fulfilled. Note: In particular the following requirement from 3 is relevant: For this release of UE-split the USIM and the ISIM shall reside on the same UICC (i.e., the ISIM application shall require the presence of a USIM application on the same UICC). This shall not preclud
47、e the possibility in later releases of having an ISIM in a UICC that does not contain a USIM. Note: The following maybe later moved into an appropriate stage 2 document if considered necessary. The functionality split required in this case corresponds to generic way computers treat other types of ne
48、twork interface cards. In this configuration the basic 3GPP protocols are implemented in the 3GPP defined radio module (see figure below). The computer contains the following elements: - driver software to control the 3GPP radio module and interface it to the computer operating system - software app
49、lications using network protocols (such as IP) which are routed to other computers via the card. MT (UMTS Module eg a PC Card) TE (Computer eg a PC) UICC Basic UMTS Protocols? UMTS Driver Software? Operating System Application API Software elements Key Figure 3: Assumed Topology 5 Requirements Requirements are identified for only the single active subscription for each TE-MT combination case. Requirements for the other more general cases may be added in later releases. 5.1 General 1 The functionality split proposed applies to Circuit Switched (CS) d
