Description

The Association for Computing Machinery (ACM) is the world's largest educational and scientific computing society. It delivers resources that advance computing as a science and a profession. ACM provides the computing field's premier Digital Library and serves its members and the computing profession with leading-edge publications, conferences, and career resources. Within the context of 3GPP specifications, ACM is referenced not as a network function or protocol, but as an authoritative source for established computing principles, algorithms, and classification systems. For instance, 3GPP technical reports and specifications may cite ACM's Computing Classification System (CCS) to categorize research areas or reference seminal papers published in ACM journals or proceedings that underpin algorithms used in areas like data compression, security cryptography, or network optimization. The references to ACM in 3GPP documents (e.g., TR 21.905, TR 38.811) typically appear in bibliographies or normative references, acknowledging the foundational work upon which certain technical implementations are built. This highlights the interdisciplinary nature of telecommunications engineering, which relies on robust computer science fundamentals. The ACM Digital Library, a vast repository of full-text articles from ACM journals, magazines, conference proceedings, and newsletters, serves as a key resource for researchers and engineers developing the algorithms that eventually become standardized. Therefore, while ACM does not define 3GPP protocols, it represents the broader academic and professional ecosystem that supplies the theoretical and practical advancements leveraged by standardization bodies. Understanding its role is crucial for appreciating the provenance and intellectual foundations of some technical solutions embedded within mobile communication standards.

Purpose & Motivation

The purpose of the Association for Computing Machinery, founded in 1947, is to advance the art, science, engineering, and application of information technology. It serves to foster the open exchange of information, promote the highest professional and ethical standards, and provide a platform for computing professionals and academics to collaborate. In the specific context of its citation within 3GPP documents, ACM's purpose is to provide a vetted, peer-reviewed source of foundational knowledge. 3GPP, as an engineering-focused standardization body, often builds upon proven computer science research rather than reinventing core algorithms. Referencing ACM publications allows 3GPP to normatively point to stable, externally maintained definitions and methodologies, ensuring technical rigor and avoiding duplication of effort in specifying low-level algorithmic details. This practice addresses the limitation of standards bodies needing to remain focused on system architecture and interoperability, while still relying on the latest advancements from the research community. It creates a vital link between academic discovery and industrial implementation, ensuring that mobile network standards incorporate state-of-the-art thinking in relevant computational fields.

In Release 18, the "ACM" function's main introduction was the clarification of the association between specific entities, alongside formalizing that an MC gateway UE is associated with a single MC service. Additionally, the specification updated references by removing the obsolete IETF HTTP RFC 7231.

  • Clarify the association between certain entities TS 23.280CR0314
  • MC gateway UE association with one MC service TS 23.280CR0341
  • Reference to obsoleted IETF HTTP RFC 7231 TS 24.259CR0056
Rel-19 9 changes

In Release 19, the ACM function introduced new procedures for user and group configuration management, including a Common ACM Procedure and specific mechanisms for ACM Group configuration. It expanded client user profile configuration data with authorized actions and enhanced migration support by updating MC service UE initial configuration and user profiles assigned from partner MC systems. Furthermore, the release added capabilities for ACM to provide interconnection MC service group IDs.
