摘要:
A system is disclosed for providing inter-system mobility in integrated LTE and WiFi systems. A control plane interface referred to as the S1a-C interface, is defined between a trusted WLAN access network (TWAN) and a mobility management entity (MME) comprised in an LTE wireless access network. A user plane interface, referred to as the S1a-U interface, is defined between the TWAN and a server gateway (SGW) in the LTE wireless access network. The MME operates as a common control plane entity for both LTE and TWAN access, while the SGW operates as a user plane gateway for both LTE and TWAN. The integrated MME and SGW allow for user equipment (UE) to access the capabilities of a packet data network (PDN) through either the LTE access network or TWAN.

Systems, methods, and apparatus embodiments are described herein for controlling policy in integrated small cell and Wi-Fi networks (ISWNs). It is recognized herein that multiple actors within an ISWN may have needs or preferences that conflict with each other, and that the best way of reconciling those conflicting needs is not always to simply give one actor preference over another. As described herein, optimum management decisions may be dynamically based on current network conditions and preferences of multiple actors.

Applicants disclose an inter-system mobility anchor control point that is adapted to initiate handover of an existing communication connection in an integrated small cell and WiFi (ISW) network. The inter-system mobility anchor control point is communicatively coupled to both an HeNB/LTE network and trusted WLAN access network (TWAN) and adapted to operate as a common control plane entity for both HeNB/LTE and TWAN access. The mobility anchor control point may be, for example, a mobility management entity (MME) or an integrated small cell and WLAN gateway (ISW GW). The mobility anchor control point is adapted to request and receive measurement data relating to the operations of the HeNB network and WLAN. Based upon the measurement data, the mobility anchor control point determines whether an existing communication path via one of the HeNB/LTE network and WLAN should be handed over to the other of the networks. Upon determining a handover should be made, the mobility anchor control point coordinates the handover.

A mobile network operator (MNO) may control WiFi QoS. 3GPP has specified control mechanisms for various levels of quality of service (QoS) over the cellular access and core network. Embodiments described herein provide differentiation of WiFi QoS based on MNO requirements. In particular, extensible authentication protocol (EAP) and diameter messages may be extended to include a wireless local area network QoS parameter. This may be used by user equipment to set the uplink 802.11e User Priority (UP) for offloaded or evolved packet core-routed WiFi traffic.

Access network discovery and selection function (ANDSF) policies are extended to include a wireless local area network quality of service (Qos) parameter in order to create a ANDSF based QoS. This may be used by user equipment to set the uplink 802.1 1e User Priority (UP) for offloaded or evolved packet core-routed WiFi traffic.

The quality of service of access to an evolved packet core network provided to a user equipment via a trusted wireless local area network is controlled by a mobile network operator via the provision of a quality of service policy to various network devices, monitoring of the character of data flows to and from the user equipment, and adjustment of differentiated service code point marking and 802.1 1.e user priority according to the policy.
