19、 15.0.0 Release 15Foreword This Technical Report has been produced by the 3rdGeneration Partnership Project (3GPP). 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 present docum

20、ent, 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 change contr

21、ol. 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 features such

22、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 software as well

23、 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 V15.0.0 (2018-07)53GPP TR 22.944 version 15.

24、0.0 Release 151 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 equipment com

25、ponents 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 documents contai

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.

34、pment 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 to introduce

35、 concepts and not imply any limitations or physical form for user equipment.

36、 also contain one or more TEs. 4.2 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 Internet and computing technologies. The objective of this report is to ETSI ETSI TR 122 944 V1

37、5.0.0 (2018-07)73GPP TR 22.944 version 15.0.0 Release 15identify 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 - be simple

38、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 separate from the MT

39、 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 take advantage

40、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 will facilitate

41、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 scenario considered

42、 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 IUMTS/GSM/GPRSNe

43、tworkTE 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 active. In this r

44、elease 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 of the PC or

45、PDA (similar to an embedded modem) or a removable module such as a PC card. 4.3 Assumptions The following assumptions are made: ETSI ETSI TR 122 944 V15.0.0 (2018-07)83GPP TR 22.944 version 15.0.0 Release 15a The transport link between the TE and MT functions of the UE is not necessarily secure. b A

46、 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 transferred out

47、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 release of U

48、E-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 following maybe l

49、ater 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 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 applications using network protocols (such as IP) which are routed to other computers
