Fixed Mobile Convergence
The document discusses fixed-mobile convergence (FMC), which aims to provide seamless communication services regardless of access network. FMC is enabled by converging telecom networks on an all-IP infrastructure using IMS. This allows any service to be accessed from any device over either fixed or mobile networks. However, FMC faces challenges regarding number plans, directory services, spectrum allocation and interconnection charges between networks. Overall, FMC has the potential to offer users integrated communication services with the benefits of both fixed and mobile networks, but also requires new investments and standards to address complex network integration issues.

Inderjit Singh IMS -Key element of the Network Evolution IMS (IP Multimedia Subsystem) is the common control infrastructure for real- time and non-real-time peer-to-peer multimedia services and any mixture of those. IMS is designed and standardized by 3GPP to integrate smoothly with existing mobile and fixed networks. New and existing services (e.g. Presence, Location) and applications can be connected and controlled by IMS through the standardized ISC interface. By using SIP (Session Initiation Protocol) IMS based services can be accessed from any IP/SIP capable device (UMTS, GPRS, WLAN, wireline users, etc. ).

Editor's Notes
- #22 From an architectural point of view we have 3 horizontal layers in IMS: Connectivity & Access layer: IMS is intended to be an access-independent architecture. Interfaces for various access networks have been defined: GPRS, UMTS, GSM, WLAN, xDSL, PSTN, IP Control layer: SIP is the signalling protocol for IMS, and in this layer we find SIP-based core elements – the new parts in your network – as well as gateways to existing access networks; those are partly reused elements like the Media Gateway in the 3GPP Release 4 architecture. Application layer: Different kind of applications ca be used and re-used: SIP-based AS, legacy IN services over CAMEL interface (e.g. SMS, Calling Cards) and 3rd party AS via an OSA-gateway. For the completeness of an operator network, components for alarming, provisioning, charging and number mapping have to be existing as well.
- #23 But to execute on a fixed-mobile strategy, we must have centralized control over the network infrastructure, the access to that infrastructure, and the services, applications and content that are delivered to end users. The 3GPP group has defined that control through its IP Multimedia Subsystem specification, which describes how 3G operators can bring new applications to wireless users and has emerged as a way to control the convergence of fixed-mobile networks.
- #24 IMS is defined as a network architecture that defines functional elements. Each functional element does not have to relate one-to-one to a physical element. A number of functional elements can be incorporated into a physical element depending upon a vendors implementation. The Service Architecture defines standard methods for services to be introduced while the Core Network defines the interactions between functional elements. IMS is multimedia. Therefore you need to think beyond a typical voice call. The context could be voice, video or graphics; or a combination correlated between two or more parties. IMS begin with 3GPP and ETSI, both which have their roots in Europe. To introduce IMS in the U.S. there are some adoptions that will be needed to accommodate U.S. nuances. It is likely that these will be handled by TIA and ATIS. IMS relies heavily existing standards developed by the IETF. Organizations representing IMS are also heavily influencing the IETF activity to evolve or develop new standards needed to complete the IMS picture. FMC – Fixed Mobile Convergence is the new buzz word of the industry. IMS’s intended applicability is across wireless, wireline, cable, enterprise and other networks. One of the major attributes, which may have more play in wireless, is the idea of service transparency no matter what network you are in (e.g. the home or visited network). There is a recognition that IMS must evolve into the networks and that there needs to be interworking between existing functionality and the newly envisioned capabilities.
