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
22、 contents of the 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 approv
23、ed document under 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 This Technical Report identifies
24、 the issues and needs surrounding messaging solutions related to the 3GPP IP Multimedia Subsystem (IMS). The report is 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
25、and contrasts the messaging capabilities of the 3GPP Multimedia Messaging Service and how these messaging capabilities 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 th
26、ey relate to the identified requirements. Finally, conclusions are drawn on the possible actions 3GPP may wish to take 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
27、3GPP multimedia messaging user experience. IMS messaging mechanisms should re-use industry wide specifications as far 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 an
28、d features, flexible service offerings and to adopt and support existing pre and post-paid billing models. ETSI ETSI TR 122 940 V13.0.0 (2016-01)63GPP TR 22.940 version 13.0.0 Release 131 Scope The objective of this Technical Report is to: a) Describe use cases that illustrate the service requiremen
29、ts for IMS messaging. b) Derive the broad 3GPP requirements for IMS messaging services. c) Investigate the possible requirements for interworking with networks outside the 3GPP domain d) Develop an analysis of the possible interaction between IMS messaging services and existing 3GPP messaging servic
30、es (SMS, EMS and MMS) as well as other relevant 3GPP services such as presence IMS group management and so on. e) Identify 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
31、new standards. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

37、SIP Session Initiation Protocol SMS Short Message Service 4 Messaging services 4.1 Background In todays world there 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
38、been designed for a wireless environment, whereas Instant Messaging has been designed for a wired environment. The 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
39、 is stored ready for collection or delivery at a later date. This section investigates current messaging services 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
40、 time by the user, are currently only being offered within the wired world, whereas all standardized services within 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
41、 wired environment. For example bandwidth, limited footprint/memory in the terminal, charging and billing. It is therefore 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 foll
42、ows: 4.2 SMS The SMS messaging service allows a message to be created on a mobile device irrespective of whether the 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
43、for the SMSC to deliver the message to the recipient. (please note that it is technically possible to send the message 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
44、cannot be guaranteed due to the fact that there is no communications association between the originator and the recipient, only the originator and the SMSC, and therefore the SMS service should not be considered as a real time service.

45、.0.0 Release 134.3 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 Messaging Service, MMS, shall succeed this easy to use, non real-time text transmission service. The MMS will al
46、low users to send and receive messages exploiting the whole array of media types available today e.g. text, images, 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
47、 device does not have to be connected to a network in order to create a message. Once connected to the network the 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 pro
48、cess 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
49、 can then connect to their mailbox to retrieve the message or have the message pushed to them. Unlike SMS where there is a degree of expectancy of a real time service, users may perceive that the service is non real time. Neither the originator nor the recipient perceives that the message will be delivered in real time, more of a service where a message can be deposited and retrieved at the recipients will. 4.4 Instant Messaging Instant Messaging is becoming popular within the Internet world although interoperability between se
