WLANs provide high data rates in a small range of homes and hotspots, while cellular networks offer greater flexibility and ubiquitous coverage, but at lower data rates, if combined with the advantages of both, users will Can benefit from it. Within the coverage of WLAN access points, multimode terminals use WLAN for data access and VoIP (voice over Internet Protocol) applications, while also using overlapping cellular networks for voice calls or media access.

With the development of network technology and the demand of users for services, heterogeneous networks will support multi-connection capabilities of multi-mode terminals, enabling terminals to simultaneously communicate with multiple network connections, carrying one or more services. Because different network connections have different characteristics and transmission capabilities, they can better meet the diverse needs of users.

The Multi-Connection Functions (MCF) is responsible for maintaining the available multi-connection information of the multi-connection terminal and managing the transmission traffic of the terminal in different access networks. The MCF includes the following functional entities:

The multi-connection control function entity (MC-FE, Multi-connection Control - Functional Entity) is responsible for IP layer routing under multiple connections of user equipment (UE).

Multi-connection registration functional entity (MR-FE, Multi-connection Registration - Functional Entity ), responsible for the available connection management of the UE, maintaining the available connection information.

The MCF has information interaction with the Policy Storage - Functional Entity (PS-FE) or the Resource and Admission Control Functions (RACF). Among them, the PS-FE is responsible for storing the carrier's connection strategy, such as bandwidth, cost, quality, security, and so on.

The RACF is a standard for resource admission control established by the International Telecommunication Union-Telecommunications Standardization Sector (ITU-T). In the latest RACF draft published by ITU-T, the functional framework of RACF is provided. As shown in Figure 1, RACF consists of two parts, namely, Policy Decision Functional Entity (PD-FE) and transmission resources. TRC-FE (Transport Resource Control Functional Entity), where the TRC-FE interacts with the transmission function through the Rc interface, and interacts with the Transport Resource Enforcement Functional Entity (TRE-FE) through the Rn interface; The PD-FE interacts with the TRC-FE through the Rt interface, interacts with the Customer Premises Network (CPN) through the Rh interface, and interacts with the Policy Enforcement Functional Entity (PE-FE) through the Rw interface. Interacting with the service control function (SCF, Service Control Functions) of the service layer through the Rs interface, interacting with the Network Attachment Control Functions (NACF) through the Ru interface, and the PD-FE interacts with other next generation networks through the Ri interface ( NGNs) interaction.
