Abstract: A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.

Abstract: A communication device configured to provide Web real-time communication (WebRTC) for internet protocol (IP) multimedia services utilizing one or more 3GPP protocols. The communication device can be configured to authenticate communication with one or more clients using one or more IP Multimedia Subsystem (IMS) credentials. The communication device can also be configured to convert communications between WebRTC and 3GPP protocols utilizing Traversal Using Relays around Network Address Translation (TURN) functionality implemented within the communication device.

Abstract translation: 一种通信设备，被配置为利用一个或多个3GPP协议来提供用于因特网协议（IP）多媒体业务的Web实时通信（WebRTC）。 通信设备可以被配置为使用一个或多个IP多媒体子系统（IMS）凭证认证与一个或多个客户端的通信。 通信设备还可以被配置为使用在通信设备内实现的网络地址转换（TURN）功能的跨越使用继电器来在WebRTC和3GPP协议之间转换通信。
