22、d in the document. Introduction In todays world there are many different types of messaging services 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 a
23、re designed to be used in what is perceived as real time, whereas others are designed as a mailbox service 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
24、3GPP IP Multimedia Subsystem (IMS) taking into consideration use cases that illustrate the needs of 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 incorpora
25、tes one or more of the following messaging types Immediate messaging and Session based messaging. With 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 use
26、rs before communication can take place. In the simplest form Session based messaging maybe a direct 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 i
27、nteroperable messaging services that use Immediate and/or Session based message types. ETSI ETSI TS 122 340 V13.0.0 (2016-01)53GPP TS 22.340 version 13.0.0 Release 131 Scope The present document specifies the stage one description of the IMS Messaging services. Stage one is an overall service descri
28、ption and defines service requirements, primarily from the subscribers and service providers points 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 manu
29、facturers. The present TS contains the requirements for IMS Messaging services, which are sufficient 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
30、services should be sufficiently flexible to allow for possible enhancements. Additional functionalities 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 require
31、ments of the service. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

38、s. IMS messaging services comprise of one or more types: Immediate messaging and Session based messaging.

40、ces in the IMS As 3GPP has developed the concept of IMS it is thought useful to consider how a SIP 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.
41、It therefore appears that SIP based messaging would be a potential candidate to provide the equivalent 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 in
42、teraction with presence information where users are able to see who is on-line as well as their 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
43、 IM exchanges and may be created by users or service providers. Additionally, chat rooms can be 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 als
44、o able to send private messages to the chat room or even privately to some participant. Unfortunately, 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 interoperabl
45、e messaging between their respective users. Additionally, internet based services do not take 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 furt
46、her elaborate the essential messaging characteristic of these services and state how they may 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

48、 divided to two different main classes based on the expectation of the sender. The sender either 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 b
49、ased on the actions required form the user before he can engage in a communication. The user can 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 b
