The 3G4G Blog: MAMS (Multi Access Management Services) at MEC integrating LTE and Wi-Fi networks

Came across Multi Access Management Services (MAMS) a few times recently so here is a quick short post on the topic. At present MAMS is under review in IETF and is being supported by Nokia, Intel, Broadcom, Huawei, AT&T, KT.

I heard about MAMS for the first time at a Small Cell Forum event in Mumbai, slides are here for this particular presentation from Nokia.

As you can see from the slide above, MAMS can optimise inter-working of different access domains, particularly at the Edge. A recent presentation from Nokia (here) on this topic provides much more detailed insight.

From the presentation:

• MAMS (Multi Access Management Services) is a framework for

- Integrating different access network domains based on user plane (e.g. IP layer) interworking,

- with ability to select access and core network paths independently

- and user plane treatment based on traffic types

- that can dynamically adapt to changing network conditions

- based on negotiation between client and network

• The technical content is available as the following drafts*

- Multi Access Management Services (MAMS) Framework – https://datatracker.ietf.org/doc/draft-kanugovi-intarea-mams-framework/

- MAMS JSON definitions of Control Plane Messages: https://www.ietf.org/id/draft-agarwal-intarea-mams-protocol-json-00.txt

- MAMS User Plane Specification: https://tools.ietf.org/html/draft-zhu-intarea-mams-user-protocol-02

The slides provide much more details, including the different use cases (pic below) for integrating LTE and Wi-Fi at the Edge.
