Info

The device can inform the network about its supported applications and services during the IMS registration. This triggers the network to do an optimal forking of incoming application SIP requests. By using either of the two RCS capability discovery mechanisms (OPTIONS or Presence), the device can show the applications supported by other users in the address book. An incoming application SIP request is dispatched from the IMS stack to the IMS communication service onto the targeted application via an API, according to Figure 15. The APIs shown above should be standardized by Service Delivery Organizations (SDO) such as OMA/W3C and utilized by the GSMA. Application ID reservation can be done by email to the TSG CT WG1 Secretary. For more information, visit http://www.3gpp.org/Uniform-Resource-Name-URN-list. E2E VIEW Figure 16 shows that how operators can settle their interconnection agreements on the level of IMS communication services rather than on the applications using these services. As a result, networks can become transparent to application innovation which is a key enabler to boost new applications with zero network impact. Figure 16. Cross-Operator Application Traffic Flow Through an IMS Communication Service 3GPP has always intended to allow applications to communicate using IMS services. This section is an effort to present this intention in a condensed way to shed some light on how devices and networks should behave to facilitate good role-play between applications and services within devices and between networks.

EVOLUTION OF COMMUNICATION AND MESSAGING - PATH TO RCS RECOMMENDATIONS AND GUIDELINES FOR RCS IMPLEMENTATION OVERVIEW This section describes RCS in the communication evolution. It also discusses how operators can embrace this evolution and at the same time preserve their existing service business. When the RCS specification is updated and evolved with new use cases and features, operators can incorporate them into their evolution of existing messaging, telephony and contact management services. RCS brings multi-device support to keep up with today’s users’ lifestyles. For example, it minimizes the difference between telecom services available on various user devices such as smartphones, tablets and laptops. Similarly, device vendors can utilize and build on their existing UIs to seamlessly support new use cases and features. marketing requirements differ in different regions, so there are two RCS implementation guidelines developed, one for North America (PRD RCC.59) and one for Europe to help OEM RCS implementations. In order to secure communication interoperability and efficient network and device deployments, there should be one globally unified and consolidated profile of RCS-based features going forward. With the exception of the capability-discovery feature, each operator can then choose to implement features from the unified and consolidated RCS profile without needing to agree with other operators about implementing the exact same features. MESSAGING EVOLUTION RCS Messaging services can be used to eventually replace legacy SMS and MMS, thus eliminating the need for operators to maintain the associated legacy messaging infrastructure. While RCS endorses and includes VoLTE and SMS over LTE services, it brings an enriched user experience. That’s accomplished via an integrated service experience in the device and through addition of new messaging features based on latest industry standards, such as OMA CPM. OMA Converged IP Messaging provides the standard evolution support for interoperability of the RCS Messaging features, multi-device handling, converged message store and interworking procedures of CPM Messaging with SMS and MMS. RCS brings in the converged messaging view where legacy (SMS and MMS) and IMS-based messages, media and files are being exchanged between users via the appropriate technologies selected based on users’ access and service capabilities, as well as the existing services agreements at inter-operator NNI. The targeted experience is smooth messaging communication between a VoLTE-only enabled device, a RCS client and a legacy device, such as using SMS on 2G. CPM Message Store defines a Common Message Store. This enables storage of IMS-based messages, legacy messages (such as SMS and MMS messages), multimedia and files exchanged. This design creates the possibility to accommodate other storage objects (e.g., VVM objects) in the future. In deployments where a mix of VoLTE-only devices, RCS Messaging clients and legacy devices coexist, RCS provides adapted delivery models for each client/device type. The RCS Messaging Server may determine the type of client(s) that a user has by making use of IMS Core features such as third-party registration to obtain the IMS Communication Identifiers (ICSIs) supported by each client. Alternatively, client capabilities of the user can be obtained via RCS capability discovery mechanisms using OMA The Evolution of 3GPP Communications Services – 5G Americas – July 2016 42
