1.  Introduction

   With the rapid development of AI terminal technology and the
   popularization of multi scenario networking requirements, scenarios
   such as home security remote field visits, remote office
   collaboration, and mixed access of fixed and mobile networks have
   gradually become the core needs of users.  In these scenarios,
   collaborative interaction between heterogeneous AI agents is the key
   to realizing service value - for example, in home security scenarios,
   mobile AI agents need to interact with camera AI agents to transmit
   real-time images, while linking NAS storage AI agents to save
   abnormal recordings; In the scenario of mixed access between fixed
   and mobile networks, the mobile terminal AI agent needs to rely on
   the fixed network gateway AI agent to achieve seamless network
   switching and dynamic bandwidth allocation.

   However, the effective collaboration of heterogeneous AI agents faces
   problems such as inconsistent data exchange formats, unstable cross
   network transmission, and insufficient security verification.  These
   issues directly affect the reliability of service execution: for
   example, video transmission delays may lead to delayed handling of
   safety risks for the elderly, and incompatible network configuration
   information may cause fixed mobile network switching failures.  To
   address these issues, there is an urgent need for a specialized AI
   communication protocol to provide core support.

   This document focuses on the ubiquitous access collaboration
   scenarios, explores the requirements for AI agent communication
   protocols.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and

   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.  Abbreviations and definitions used in this
   document:

3.  Use Cases

3.1.  Remote Care

   In the scenario of remote access for home security, remote care for
   the elderly, children, and pets is achieved through the collaboration
   between mobile terminal AI agents and home fixed network device AI
   agents (such as cameras, NAS storage, printers, pet sensors).  The AI
   agent communication protocol provides core support for the
   collaboration between the two.  The participating roles include users
   operating mobile AI agents, mobile AI agents responsible for sending
   and receiving requests, and home device AI agents executing
   instructions.  When the user checks the status of the elderly, if the
   phone adjusts the camera screen and there is an abnormality, it
   triggers the NAS to store the video; When remotely printing materials
   for children, the phone wakes up the printer; When pets move
   abnormally, sensors will push alarms, etc.  Users can obtain real-
   time status, normal data transmission, and timely handling of
   anomalies.  The protocol needs to ensure real-time data, request
   verification, and privacy security.

3.2.  Remote Work

   In remote work scenarios, efficient remote work is achieved through
   collaboration between terminal AI agents (such as mobile phones and
   laptops) and office equipment AI agents (such as cloud desktops,
   printers, video conferencing terminals, file sharing servers).  The
   communication protocol of the AI agents provides core support for the
   collaboration between the two.  The participating roles include
   employees who operate terminal AI agents, terminal AI agents
   responsible for command sending and receiving, and office equipment
   AI agents that execute tasks.  When employees need to work, connect
   the terminal to the cloud desktop; When remotely printing files, the

   terminal wakes up the printer; When holding a meeting, the terminal
   starts the video conferencing terminal and shares files, etc.
   Employees have access to office resources, stable data transmission,
   and smooth collaboration.  The protocol needs to ensure stable
   connection, permission control, and data encryption.

3.3.  Multi Access Collaboration

   In the scenario of multi access collaboration, seamless device
   switching and dynamic allocation of network resources are achieved
   through the collaboration of mobile terminal AI agents (such as
   mobile phones and tablets) and fixed network gateway AI agents (such
   as home optical cats and enterprise routers).  The AI agent
   communication protocol provides core support for the collaboration
   between the two.  The participating roles include users who operate
   mobile network terminals, mobile network terminal agents responsible
   for dynamic access, and fixed network gateway agents responsible for
   resource scheduling.  When the user is at home, the mobile network
   terminal automatically connects to the fixed network gateway to
   obtain high bandwidth; When going out, the fixed network gateway
   pushes the network configuration to the mobile network terminal to
   ensure seamless networking; When multiple devices are accessing
   simultaneously, the fixed network gateway links with the mobile
   network terminal to allocate bandwidth resources, etc.  Users can
   achieve seamless network switching, stable device access, efficient
   resource scheduling, and protocols need to ensure continuous
   connection, permission control, and bandwidth adaptation.

4.  Requirement

4.1.  Identity Authentication and Request Verification

   Before executing interaction requests between agents, strict identity
   authentication must be performed.  The protocol shall define high-
   security authentication mechanisms - such as digital certificates and
   mutual authentication - to ensure that only legitimate and authorized
   agents can initiate or receive commands, thereby preventing
   unauthorized access and malicious control.

4.2.  Service Discovery and Automatic Negotiation

   When an agent accesses a network (e.g., home or office network), it
   shall automatically discover other available agents and their
   provided services (e.g., printing, video conferencing, storage).  It
   shall also automatically negotiate capabilities and establish
   connections to enable "plug-and-play" functionality.

4.3.  Unified Communication Protocol

   A standardized set of message formats, command sets, and interaction
   workflows shall be defined for inter-agent communication.  This
   ensures that agents from different manufacturers and of different
   types, e.g., mobile devices, cameras, printers, routers, can
   identify, understand, and execute commands with one another.

4.4.  Connection Stability and Seamless Handover

   In multi-access collaboration scenarios, when a user switches from a
   home network to mobile network, the protocol shall support session
   persistence and seamless handover for agents.  This guarantees the
   uninterrupted operation of ongoing services.

4.5.  Local Disaster Recovery and Offline Processing Capabilities

   In the event of network outages or other anomalies, critical agents
   (e.g., home gateways, network-attached storage/NAS) shall possess
   local decision-making and data processing capabilities.  For example,
   after a network disconnection, home sensors shall continue to locally
   record abnormal events and synchronize the recorded data to the cloud
   and mobile terminals once the network is restored.

5.  Security Considerations

   TBD

6.  IANA Considerations

   TBD
