NOTE: The parts above refer to the active work items and published standards within ETSI. These work items do not include MMS over NGN. Introduction The
18、 Short Message Service (SMS) has paved the way for a new approach to personal communication. Following the success in mobile telecommunication networks, SMS has also become in fixed line telecommunication networks a well-known feature. Based on ETSI standards, SMS offers the possibility of exchangin
19、g Short Messages within and between fixed line and mobile telecommunication networks. ETSI ETSI TR 102 314-3 V1.1.1 (2005-03) 5 The Multimedia Messaging Service (MMS) in the mobile networks was created to provide a sophisticated kind of messaging which combines the advantages of both SMS and email m
20、essaging. The Multimedia Messaging Service (MMS) allows users to send and receive messages exploiting the whole array of media types available today e.g. text, images, audio, video and even streaming contents, while also making it possible to support new content types as they become popular. Similar
21、 to the Short Message Service (SMS), the Multimedia Messaging Service (MMS) is a non-real-time delivery system providing a store-and-forward mechanism. A good overview about the Multimedia Messaging Service can be found in TS 102 314-1 1. A Multimedia Message (MM) consists of one or more media eleme
22、nts (such as text, voice, image and video), and it is the combination of these media elements in an ordered synchronized manner that creates a multimedia presentation. The non-real-time multimedia messaging service shall be capable of supporting current and future multimedia messaging based services
23、, and exploit the advances being made in the world multimedia community. The Multimedia Messaging Service for fixed telecommunication networks follows the philosophy of adopting the existing Multimedia Messaging Service of mobile networks as widely as possible. Following this philosophy, only the mo
24、bile network-specific transport mechanisms are replaced by transport mechanisms applicable to fixed networks. The higher, not mobile network-specific MMS protocol layers are used similar to their respective use in mobile networks. Following this approach F-MMS interworking should be based on the exp
25、erience and roadmap of the MMS approach in the mobile world. However, it needs to be recognized that there exist some major differences between mobile and fixed telecommunication networks. Due to these differences e.g. the routing problem in fixed networks may be more complex than in mobile networks
26、, i.e. that the solution for number portability for MMS applications may be different. Clarification is e.g. needed in realization of number databases and on which operator a recipient resides with a given address for mobile MMS; these problems can be solved by HLR lookups (SS7). For Fixed MMS, no s
27、uch infrastructure exists, hence the need for new solutions. The MMS is a service that shall make it possible to offer seamless MMS over different networks (PSTN, ISDN, PLMN). To fulfil seamless interworking over different networks and/or via different service providers an interconnection between th
28、ose parties is essential. ETSI ETSI TR 102 314-3 V1.1.1 (2005-03) 6 1 Scope The present document gives a guideline about different network architectures and interconnection possibilities to allow interworking between different networks (PSTN, ISDN, PLMN) and/or via different service providers for me
29、ssaging services (SMS/MMS) in fixed networks. The present document describes the high level architecture for routing possibilities for the provision of non real-time Multimedia Messaging Services in fixed telecommunication networks between different MMSCs. Underlying specific technical solutions and
30、 their corresponding protocols are outside the scope of the present document and are described in separate specifications and standards which are based on the philosophy of adopting the existing MMS of mobile networks as far as possible. E.g. determination of the destination address should be based
31、on TS 123 140 2. The present document contains a recommendation towards MMS interworking issues. Charging principles are outside the scope of the present document. The present document includes guidelines applicable to network operators and service providers to provide a complete service for messagi
32、ng services. The present document describes two different interworking principles as well as different scenarios to come to a final solution. The present document does not deal with interfaces and protocols between different entities. 2 References For the purposes of this Technical Report the follow

34、ons For the purposes of the present document, the following terms and definitions apply: carrier: licensed telecommunication company who provides telecommunication services and services for call or message routing purposes NOTE: Therefore, a carrier has got assigned ranges of E.164 numbers. MMS prov
35、ider: organization offering MMS to a group of customers which can be also a carrier but it is not necessarily limited to carriers portability data: unique association of an E.164 number (MSISDN), the destination carrier (MCC and MNC) and an MMS address for the destination carrier NOTE: The carriers
36、choose an implementation based on their need (e.g. query for each call or query on demand which requires a complete database or Onward Routing that only requires database storage of out-ported and possibly in-ported numbers) which is according to national solutions for number portability. ETSI ETSI
37、TR 102 314-3 V1.1.1 (2005-03) 7 portability database: carrier database containing local, in-ported and out-ported E.164 numbers of interconnect partners as well as E.164 numbers ported between different carriers of the same portability region NOTE 1: Local numbers (typically ranges) are numbers belo
38、nging to the carrier; in-ported numbers are numbers ported from another carrier inside the portability region; out-ported numbers are numbers ported to another carrier inside the portability region; interconnect partner numbers (typically ranges) are numbers belonging to interconnect carriers outsid
39、e the portability region. NOTE 2: An originating carrier stores portability status for the dialled number locally if the destination operator is in the same portability region. The originating carrier does not store portability data locally for numbers of carriers in other portability regions. NOTE
40、3: Either the carrier who “looses“ (donor) or the carrier who “receives“ a number in a portation has the responsibility to inform the other carriers of the new destination carrier. The same applies for numbers belonging to a number block of carrier “A“ which have migrate to carrier “B“ and then to t
41、he carrier “C“. NOTE 4: In practical implementations a country, a number block or a group of mobile operators are examples of portability regions. portability region: group of carriers that share portability data NOTE 1: Number migration is only allowed inside a given portability region. NOTE 2: Eac
42、h carrier stores number ranges assigned to its interconnect partners. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: 3GPP 3rd Generation Partnership Project DB Data Base ENUM Electronic NUMbering F-MMS Fixed network MMS F-MMSC Fixed network MMSC FQDN F

In all the following concepts, i
46、t is assumed that this condition is fulfilled. The following concepts describe F-MMS address resolution variants focussed on dedicated portability regions. Within the defined portability region a direct address resolution is assumed. Addressing of recipients from outside the portability region may r
47、equire MM4 hopping (relaying) by using a local MMSC as gateway as far as no suitable solutions are available across the portability regions (e.g. ENUM). 5 Solution 1 - Network Operator Database 5.1 Solution 1a - Local number database without references 5.1.1 Concept In this solution it is assumed th
48、at F-MMS is a carrier related service and that the F-MMS service for a specific customer can only be provided by this customers telephony access carrier. Therefore, the already existing number database (including voice portability information) can be used as shown below: Local numbers. In-ported num
49、bers. Out-ported numbers with pointers to the recipient operators. Numbers ported between other carriers. NOTE: To support interworking for numbers ported from non MMS-carriers and to avoid unnecessary MM4-hops a carrier needs to know at any point in time the current carrier for a certain number. 5.1.2 Consequences for MMS providers The database is maintained by each local carrier. This concept is based on the assumption that a voice operator (carrier) controls routing information for MM transmission. Only local provisioning is involved; the MMS provider
