The tunnel/packet routing/switch information and tunnel parameters are transferred from control function to forwarding function. The charging function could be realized on control function, forwarding function or both, which depends on the implementations. The separation of the GW's control function and forwarding function could improve the deployment flexibility, such as centralized control function and distributed forwarding function deployment, without changing the interfaces to other legacy functions. Scenario 1: flexible deployment of separated control function and forwarding function Descriptions When the GW is separated into control function and forwarding function, the control function is centralized and deployed with other mobile packet core control function such as mobility management function, and policy function.

Since there are no reference points among functional components in [ITU-T Y.3502], it is necessary to adopt the grouping of DaaS functions in order to specify their reference points for convenience. Clause 9 explains the reference points based on four groups of DaaS functions as in Figure 7-1, i.e., client support functions, virtual desktop connection and delivery functions, virtual desktop resource management functions, and virtualization infrastructure functions. 9 DaaS functional architecture 9.1 Client support functions The client support functions (CS-FS) have four functions including: connection negotiation function (CN-F), client peripheral connection function (CPC-F), service connection function (SC-F), and service continuity for user environment function (SCUE-F) as shown in Figure 9-1.
