The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the
18、present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under
19、 change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The future environment will be characterised by f
20、eatures 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 a number of physical devices. For example the User Equipment may include a PC or PDA with appropriate client sof
21、tware 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 identifies scenarios and requirements for UE Functionality Split. ETSI ETSI TR 122 944 V14.0.0 (2017-03)53GPP TR 22.94
22、4 version 14.0.0 Release 141 Scope This report identifies scenarios and requirements for UEs with functionality split over multiple devices. Scenarios that are required to be supported in the standard are defined in detail. The requirements in this report should enable interoperability between user
23、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 security or other reasons. This report does not identify all prohibited scenarios. 2 References The following doc

32、GPP user equipment may take many forms. 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 make up the whole user equipment combination. An example is illustrated below. This illustration is only meant
33、 to introduce concepts and not imply any limitations or physical form for user equipment. Local Wireless Network (eg Bluetooth) Physical Connection User Equipment Combination MT TE TE TE User Equipment Components Figure 1: User Equipment Combination The user equipment combination contains at least o
34、ne MT and may also contain one or more TEs. ETSI ETSI TR 122 944 V14.0.0 (2017-03)73GPP TR 22.944 version 14.0.0 Release 144.2 Background to Requirements The support of UE-functionality split in 3GPP should aim to exploit technology trends and to promote the convergence of 3GPP technologies with Int
35、ernet 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: - correspond to likely physical scenario for available equipment - offer attractive commercial opportunities
36、 - 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 operating systems) where appropriate Allowing some 3GPP related applications to be implemented on TEs separat
37、e 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 integrate with a users other business, entertainment and communications tools. - Allowing 3GPP applications to ta
38、ke 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 output. - Integration of emerging wireless LAN technologies (e.g. Bluetooth, 802.11b) with 3GPP networks This wil
39、l 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 not need to write different applications for 3GPP defined radio modules made by different vendors. The scenar
40、io 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 one UICC as shown in Fig. 1. The user(s) identity is possibly different from the subscribers identity. TE IUM
41、TS/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 case of this scenario. In this case the restriction is that only a single subscription on the UICC may be acti
42、ve. 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 contains a 3GPP defined radio module to allow it to access 3GPP services. The module may be a (semi)permanent part
43、of the PC or PDA (similar to an embedded modem) or a removable module such as a PC card. ETSI ETSI TR 122 944 V14.0.0 (2017-03)83GPP TR 22.944 version 14.0.0 Release 144.3 Assumptions The following assumptions are made: a The transport link between the TE and MT functions of the UE is not necessaril
44、y 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). c Charging is linked to one particular USIM. d The secret key and the authentication algorithm cannot be tra
45、nsferred 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 regarding the ISIM must be fulfilled. Note: In particular the following requirement from 3 is relevant: “For this
46、 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 preclude the possibility in later releases of having an ISIM in a UICC that does not contain a USIM.” Note: The foll
47、owing 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 network interface cards. In this configuration the basic 3GPP protocols are implemented in the 3GPP defined ra
48、dio 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 applications using network protocols (such as IP) which are routed to other computers via the card.

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) domain.
