Introduction This Technical Report identifies the issues and needs surrounding messaging solutions related to the 3GPP IP Multimedia Subsystem (IMS). The report is

26、 designed to identify essential messaging requirements, taking into consideration use cases that illustrate the needs of both service providers and users. The report also highlights and contrasts the messaging capabilities of the 3GPP Multimedia Messaging Service and how these messaging capabilities

27、 might relate to or interact with the messaging services running in IMS. An evaluation of various messaging solutions and technologies is provided together with an analysis on how they relate to the identified requirements. Finally, conclusions are drawn on the possible actions 3GPP may wish to take

28、 in regards to potential future work. To encourage rapid end-user adoption and to protect existing operator investments, IMS Messaging is an evolution and enhancement of the current 3GPP multimedia messaging user experience. IMS messaging mechanisms should re-use industry wide specifications as far

29、as possible and propose extensions as necessary. It is a goal of IMS Messaging to leverage the popularity of existing messaging services by supporting end-user friendly interfaces and features, flexible service offerings and to adopt and support existing pre and post-paid billing models.

30、R 122 940 V15.0.0 (2018-07)63GPP TR 22.940 version 15.0.0 Release 151 Scope The objective of this Technical Report is to: a) Describe use cases that illustrate the service requirements for IMS messaging. b) Derive the broad 3GPP requirements for IMS messaging services. c) Investigate the possible re

31、quirements for interworking with networks outside the 3GPP domain d) Develop an analysis of the possible interaction between IMS messaging services and existing 3GPP messaging services (SMS, EMS and MMS) as well as other relevant 3GPP services such as presence IMS group management and so on. e) Iden

32、tify possible routes to standardization by: 1) Adopting existing and emerging standards, e.g. OMA, IETF. 2) Modifying and enhancing existing and emerging standards. 3) Developing of new standards. 2 References The following documents contain provisions which, through reference in this text, constitu

39、e are many different types of messaging services available both in the wired and wireless worlds. Some services are supported in both, others are only found in one. For example, SMS has been designed for a wireless environment, whereas Instant Messaging has been designed for a wired environment. The

40、 expectations of these services also differ in that some services are designed to be used in what is perceived as real time and others are designed as a mailbox service where the message is stored ready for collection or delivery at a later date. This section investigates current messaging services

41、and examines the expectations and differences between them. In summary this section highlights the important fact that services where the message is delivery in what is perceived as real time by the user, are currently only being offered within the wired world, whereas all standardized services with

42、in the wireless world can be classed as non-real time. Introducing what is perceived as real time services into the wireless world brings many challenges not currently experienced in the wired environment. For example bandwidth, limited footprint/memory in the terminal, charging and billing. It is t

43、herefore important to consider the issues and impacts that surround these types of services when deploying in a wireless world. The messaging services covered in this section are as follows: 4.2 SMS The SMS messaging service allows a message to be created on a mobile device irrespective of whether t

44、he device is connected to a network or not. Once connected to an appropriate network, the user can send the message to the originators home SMSC, where it is stored until it is possible for the SMSC to deliver the message to the recipient. (please note that it is technically possible to send the mes

45、sage to any SMSC). Because of the short delivery times sometimes experienced by users of the SMS service, it could be perceived as being a real time service. However, real time delivery cannot be guaranteed due to the fact that there is no communications association between the originator and the re

46、cipient, only the originator and the SMSC, and therefore the SMS service should not be considered as a real time service. 4.3 MMS SMS has been very successful messaging service within in the second-generation GSM system. In the third generation mobile system it is envisaged that the Multimedia Messa

47、ging Service, MMS, shall succeed this easy to use, non real-time text transmission service. The MMS will allow users to send and receive messages exploiting the whole array of ETSI ETSI TR 122 940 V15.0.0 (2018-07)83GPP TR 22.940 version 15.0.0 Release 15media types available today e.g. text, images

48、, audio, video, while also making it possible to support new content types as they become popular. As with SMS, the MMS message is created using the application on the device. Again, the device does not have to be connected to a network in order to create a message. Once connected to the network the

49、 message can be sent from the device to the originators MMS server, again similar to the SMS implementation. This can be classed as the originating process. However, the MMS delivery process differs to that of the SMS in that instead of sending the message directly to the recipient, the MMS server forwards the message to the recipients MMS mailbox. Depending on the architecture, the recipient may be notified that a new MMS message has arrived in their inbox from which the recipient can then connect to their mailbox to retrieve the
