Mobile Metaverse Service

Description

The Mobile Metaverse Service is a concept introduced in 3GPP Release 19 to define how the 5G system can provide a mobile metaverse experience to users. A metaverse is a collective virtual shared space, created by the convergence of virtually enhanced physical reality and physically persistent virtual reality. The mobile metaverse service extends this to mobile devices, enabling users to access immersive 3D environments, avatars, and interactive experiences while on the move. This service is specified in 3GPP TR 22.856 and TS 22.156, which outline the service requirements and use cases.

Architecturally, the mobile metaverse service relies on the 5G system's advanced capabilities, including ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), and massive machine-type communication (mMTC). It leverages edge computing (MEC) to process and render metaverse content closer to the user, reducing latency and backhaul load. The service also requires high-precision positioning, synchronization, and possibly network slicing to ensure dedicated resources for metaverse traffic. Key components include the UE (user equipment), 5G core network functions (e.g., SMF, UPF, NEF), and application functions that manage the metaverse sessions.

The service operates by establishing a data session between the UE and a metaverse server, often hosted at the edge. The 5G network provides QoS flows tailored to the metaverse traffic characteristics, such as high data rate and low latency. The network may also expose APIs to third-party metaverse providers for dynamic QoS and policy control. The mobile metaverse service can support various applications, including virtual meetings, gaming, education, and social interactions, all within a mobile context.

Key technical challenges addressed by 3GPP include ensuring seamless mobility, maintaining session continuity, and managing the high bandwidth and low latency requirements. The service also considers security and privacy aspects, such as user authentication and data protection. The specifications define service requirements like support for multiple users in the same virtual space, synchronization of avatars, and real-time interaction. The mobile metaverse service is expected to evolve with future releases, incorporating advancements in 5G-Advanced and 6G.

In summary, the mobile metaverse service represents a significant step in integrating immersive virtual experiences with mobile networks, leveraging 5G's capabilities to deliver a compelling user experience. It is a key driver for network enhancements in Rel-19 and beyond, aiming to make the metaverse accessible anytime, anywhere.

Purpose & Motivation

The mobile metaverse service exists to enable immersive virtual experiences over mobile networks, addressing the limitations of previous mobile services that were primarily focused on voice, data, and video. Traditional mobile networks were not designed for the high bandwidth, low latency, and real-time interactivity required by metaverse applications. The service was motivated by the growing interest in the metaverse and the need for standardized support to ensure interoperability, quality of experience, and efficient use of network resources.

Previous approaches to mobile virtual reality (VR) and augmented reality (AR) were often standalone or relied on Wi-Fi, limiting mobility and scalability. The mobile metaverse service aims to provide a seamless experience across different devices and networks, leveraging 5G's advanced features. It solves problems such as high latency, inconsistent QoS, and lack of support for multi-user interactions. By defining service requirements and architecture, 3GPP ensures that mobile operators can deliver metaverse services reliably and efficiently.

The creation of this service in Rel-19 reflects the industry's anticipation of metaverse as a major application area for 5G-Advanced and 6G. It provides a framework for operators, vendors, and application providers to collaborate and innovate, driving the development of new business models and revenue streams.
