Embodiment Construction

[0028] System overview

[0029] figure 1 An overview of main components in the communication system 1 according to the first embodiment is shown. System 1 has several functional subsystems:

[0030] Long Term Evolution (LTE) cellular network3 infrastructure;

[0031] Non-cellular network infrastructure5 including local network and Internet Service Provider (ISP) infrastructure; and IP Multimedia Subsystem (IMS)7.

[0032] In contrast to older circuit-switched networks, LTE cellular networks 3 provide data and voice services to cellular network client devices called user entities (UEs), such as mobile phones 9, using packet-switched IP networks. The LTE cellular network comprises a network core 11 and a radio access network formed by eNodeBs 13 for connecting services and resources in the network core 11 to UE 9 . The network core 11 contains standard control functions such as a Multimedia Mobile Entity (MME) (not shown), a Home Subscriber Server (HSS) (not shown), and a P...

Abstract

The application provides a wireless access point and an operation method, a method and a system for managing voice service access. The VoWiFi Service Monitor monitors the logical data path to the MNO's ePDG as an indication of whether VoWiFi service is available to users of the MNO's network. Due to the standard configuration of UEs preferring WLAN connectivity over LTE cellular connectivity, if VoWiFi service is not available, the UE will not automatically switch to VoLTE while WLAN connectivity is available between the UE and the hub. The VoWiFi Service Monitor notifies any connected hubs when a state change of the ePDG is detected. The hub receives notifications from the VoWiFi service monitor and determines for each notification whether an ePDG state change affects one or more VoWiFi enabled UEs connected to the hub. If at least one such device is affected by the change, the hub notifies the affected UEs with an instruction to switch from VoWiFi to VoLTE.

Description

technical field [0001] The present invention relates to managing wireless communication services, and more particularly to methods and devices for controlling device handover between WLAN and cellular service access. Background technique [0002] A cellular data network provides data connectivity to mobile devices that have a cellular network interface. The network consists of a network core that handles control plane functions and data packet routing, and a radio access network (RAN) of macrocell base stations located throughout the coverage area of ​​the mobile network for wireless communication with user mobile devices. An example of a cellular network architecture is Long Term Evolution (LTE). Unlike previous generations of second-generation (2G) and third-generation (3G) cellular networks that provided packet-switched data services on a circuit-switched voice platform, LTE is an all-packet-switched data network architecture that does not support traditional voice call ...
