Embodiment Construction

[0034] Applicants herein disclose systems and methods for intersystem mobility in an integrated LTE and trusted WLAN access network (TWAN). The S1a-C control plane interface is defined between a Trusted WLAN Access Network (TWAN) and a Mobility Management Entity (MME) included in the 3GPP core network. The S1-U user plane interface is defined between the TWAN and the server gateway (SGW) in the 3GPP core network. The MME operates as a common control plane entity for both LTE and TWAN access, while the SGW operates as a user plane serving gateway for both LTE and TWAN. Integrating MME and SGW allows user equipment (UE) the ability to access packet data network (PDN) through LTE access network or TWAN. Also, an existing communication connection between the UE and the PDN can be handed over from one of the LTE access network or TWAN to the other. Furthermore, the MME and the SGW achieve simultaneous maintenance of two communication paths between the UE and the packet network, o...

Abstract

A system is disclosed for providing inter-system mobility in integrated LTE and WiFi systems. A control plane interface, referred to as the Sla-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 S 1 a-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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 62 / 015,763, filed June 23, 2014, the contents of which are hereby incorporated by reference in their entirety. Background technique [0003] As wireless communication technologies evolve, additional requirements have been placed on wireless systems to support wider use of different wireless networks. For example, mobile network operators (MNOs) have begun to incorporate "carrier-grade" WiFi in a way that complements their cellular and core network services. For example, MNOs have attempted to adopt WiFi to offload Internet traffic from their cellular and core networks. MNOs have also attempted to provide users of WiFi networks with access to the Evolved Packet Core (EPC) of cellular systems. [0004] Although the need for system-to-system integration of cellular and WiFi networks is constantly increasing, existing me...
