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 document, i

20、t 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 control. y

21、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 In todays world there are many different types of messaging services

22、 available both in the wired and wireless worlds. Some messaging services are supported in both environments; others are only to be found in one. The expectations of the services differ in that some are designed to be used in what is perceived as real time, whereas others are designed as a mailbox s

23、ervice where the message is stored ready for collection or delivery at a later stage. The 3GPP Technical Report TR22.940 identifies the issues and needs surrounding messaging solutions related to the 3GPP IP Multimedia Subsystem (IMS) taking into consideration use cases that illustrate the needs of

24、both service providers and users. This Technical Specification takes the Technical Report into account when defining the requirements for the support of IMS Messaging. IMS Messaging services incorporates one or more of the following messaging types Immediate messaging and Session based messaging. Wi

25、th Immediate messaging the sender expects immediate message delivery in what is perceived as real time. With Session based messaging a communications association is established between two or more users before communication can take place. In the simplest form Session based messaging maybe a direct

26、communication between two users. This specification defines the requirements for both the Immediate message type and the Session based message type. The specification provides the ability to develop interoperable messaging services that use Immediate and/or Session based message types. ETSI ETSI TS

27、122 340 V14.0.0 (2017-03)53GPP TS 22.340 version 14.0.0 Release 141 Scope The present document specifies the stage one description of the IMS Messaging services. Stage one is an overall service description and defines service requirements, primarily from the subscribers and service providers points

28、of view, and does not deal with the details of the human interface itself. The present TS includes information applicable to network operators, service providers and terminal, switch and database manufacturers. The present TS contains the requirements for IMS Messaging services, which are sufficient

29、 to provide a complete service. The messaging types identified in this document are: immediate messaging and session based messaging. It is highly desirable that technical solutions for IMS Messaging services should be sufficiently flexible to allow for possible enhancements. Additional functionalit

30、ies not documented in this 3GPP TS may implement requirements which are considered outside the scope of this 3GPP TS. Such additional functionality shall not compromise conformance to the core requirements of the service. 2 References The following documents contain provisions which, through referen

31、ce in this text, constitute provisions of the present document. 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. For a non-specific reference, the latest version appl

32、ies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 Void 2 3GPP TS 22.250: 3rdGeneration Partnership Project; Technical Specification Group Serv

40、 based IP network can be utilised to provide messaging capabilities. One of the chief characteristics of SIP is its ability to rapidly and efficiently create real-time sessions between groups of users. It therefore appears that SIP based messaging would be a potential candidate to provide the equiva

41、lent of “Chat Room” and “Instant Messaging” (IM) type services found on the Internet today. Typical characteristics instant messaging are instant delivery of the messages to the targeted recipient(s) and interaction with presence information where users are able to see who is on-line as well as thei

42、r status. A chat room is a “place“ where multiple persons can join, follow and contribute to the ongoing discussion and leave the “room“ at any time. Chat rooms are more permanent in nature when compared to IM exchanges and may be created by users or service providers. Additionally, chat rooms can b

43、e further divided to the private and public chat rooms. Normally, users who are participating in chat room will receive all the messages that are sent by the other participants. Similarly, the users are also able to send private messages to the chat room or even privately to some participant. Unfort

44、unately, the most popular internet based instant messaging services are usually based upon closed and proprietary protocols which has made it impossible for different service providers to allow interoperable messaging between their respective users. Additionally, internet based services do not take

45、into consideration the wireless environment and the needs of operators to provide services that are commercially viable by for example, providing support for charging. This technical specification will further elaborate the essential messaging characteristic of these services and state how they may

46、be enhanced, e.g. operators may be able to create and then advertise chat rooms containing specific content where users who join the room may be charged an entrance fee, Join to chat Harry Amanda Peter Ken Invite Amanda to join to chat Join to chat Message Message Message Send a private message to K

The sender eith

48、er expects the message to be delivered immediately or he does not care so much whether the message is delivered immediately or later. The immediate case can be further divided to two different sub-classes based on the actions required form the user before he can engage in a communication. The user c

49、an both send and receive messages without any prior actions or he may be required to join to a messaging session before the message exchange can take place. The messaging types considered in this specification are - Immediate messaging: Typically, sender is aware of the availability of the recipient(s) (possibly through the use of the Presence service) before sending this type of message as, if the recipient is not available, the message may be discarded or deferred. An immediate message may be deferred by the recipients network based on th
