US Patent:

20040240441, Dec 2, 2004

Filed:

Jun 2, 2003

Appl. No.:

10/452331

Inventors:

Sundar Sriram - Naperville IL, US

International Classification:

H04L012/56

US Classification:

370/389000, 370/401000

Abstract:

A packet switched IP call to a mobile user device in a wireless network is supported where the mobile user does not have a static IP address and where the mobile user is not engaged in communications in which an IP address is currently assigned. The originating party utilizes the directory number of the mobile user to initiate the packet switched call with at least an originating packet being directed to a home agent in the wireless network. The home agent assigns a temporary IP address to the mobile user's UE and translates packets addressed to the user's directory number to the assigned IP address. A switching node forwards the assigned IP addressed packets to the corresponding UE.

Inventors:

- Louisville CO, US
Sundar R. Sriram - Aurora IL, US

International Classification:

H04W 76/15

Abstract:

Certain aspects of the present disclosure are directed towards systems and techniques for protocol data unit (PDU) session establishment. One example method generally includes sending, by a wireless device, a first PDU session establishment request to a first network, wherein the first PDU session establishment request is sent via an access network. The method may also include sending, by the wireless device, a second PDU session establishment request to a second network via the access network, receiving, via the access network, a first acknowledgement corresponding to the first PDU session establishment request, and receiving, via the access network, a second acknowledgement corresponding to the second PDU session establishment request.

International Classification:

H04W 76/15
H04W 60/00

Abstract:

Systems, methods, and devices include techniques for establishing an enhanced multi-access protocol data unit (PDU) session in a multi-network environment. Various registration procedures may be used to allocate resources between a first network (e.g., a Mobile Network Operator (MNO) and a second network (e.g., a Mobile Virtual Network Operator (MVNO). For instance, a method includes sending by a wireless device to a network, indication(s) related to network capabilities of the wireless device. The indication(s) include whether the wireless device supports a multi-access PDU session comprising a first PDU session and a second PDU session. The first PDU session is established via a 3rd Generation Partnership Project (3GPP) access the second PDU session is established via a first non-3GPP. The indication(s) include whether the wireless device supports an enhanced multi-access PDU session comprising a third PDU session, wherein the third PDU session is established via a second non-3GPP access.
