Abstract:
The present disclosure generally relates to identifying, by a processor of a wireless communications device, a service, determining, by the processor and based at least in part on the service, whether to prioritize a type of connection gateway to utilize in connecting to the service, where the processor determines to prioritize the type of connection gateway, selecting, by the processor, a connection gateway for the service based at least in part on a stored network access preference for the service, where the processor determines not to prioritize the type of connection gateway, selecting, by the processor, the connection gateway for the service regardless of the stored network access preference for the service, and connecting, by the processor, to the service via the connection gateway.
Abstract:
Wireless communication methods, devices, and systems to reduce latency when network access (e.g., cellular network access) is barred are described. A method includes receiving, by a user equipment (UE) from an application, a request for at least one of establishment of a packet data unit (PDU) session or uplink (UL) data transfer via a previously established PDU session. The method additionally includes evaluating that access to a first network (e.g., a 3rd Generation Partnership Project (3GPP) network) is barred. The method also includes determining that the access barring time exceeds a threshold, and checking, in response to the determining, that configured policies permit the PDU session to be on a second network (e.g., a non-3GPP network). The method further includes transferring data of the PDU session in accordance with the configured policies. Other aspects and features are also claimed and described.
Abstract:
In aspects of the disclosure, a method, an apparatus, and a computer program product for wireless communication by a user equipment (UE) are provided. In one aspect, the UE associates with an access point of a wireless local area network which may be untrusted, obtains a list comprising a plurality of public land mobile network (PLMN) entries and one or more selection conditions associated with each one of the plurality of PLMN entries, and selects a PLMN from the list when the one or more selection conditions associated with the PLMN are satisfied. The UE may further discover an evolved packet data gateway (ePDG) for the selected PLMN using one or more fully qualified domain name (FQDN) rules for the selected PLMN. The UE may then attach to the selected PLMN using the discovered ePDG.
Abstract:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication. A user equipment (UE) device may be connected to a first evolved packet data gateway (ePDG) via a first radio access technology (RAT). The UE may evaluate, either periodically or based on a trigger event, an ePDG reselection metric associated with the first ePDG to determine whether selecting a second ePDG different from the first ePDG is viable. The UE may then reselect to a second ePDG based on whether the ePDG reselection metric satisfies one or more selection conditions. Selection conditions may include, for example, a change in the location or public land mobile network (PLMN) of the UE, UE movement between networks, or a connection failure associated with the first ePDG.
Abstract:
A method for wireless communication at a user equipment (UE) includes determining that both a cellular radio access technology (RAT) and a wireless local area network (WLAN) RAT are available over an unlicensed radio frequency spectrum band; obtaining measurements for at least the cellular RAT or the WLAN RAT; selecting, by the UE, one of the cellular RAT or the WLAN RAT for a class of traffic, where the selected RAT is selected based at least in part on the measurements; and serving the class of traffic based at least in part on the selected RAT.
Abstract:
A method of wireless communication by a UE includes receiving an indication information; determining, based on the indication information, whether a connection of the UE is authorized to be offloaded from a first channel to a second channel; determining, when the connection is not authorized to be offloaded, whether there is an ongoing handover procedure to offload the connection of the UE from the first channel to the second channel or whether the indication information is received in a message corresponding to a request to deactivate a default evolved packet system (EPS) bearer of the connection of the UE. The method further includes disregarding the indication information when the connection is not authorized to be offloaded and it is determined that either there is an ongoing handover procedure to offload the connection of the UE from the first channel to the second channel or the message corresponds to a request to deactivate a default EPS bearer of the connection.
Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may prevent rejected attachment requests when connecting to a trusted wireless local area network (WLAN) and from a wireless wide area network (WWAN). For example, an attachment packet data network (PDN) connection may be maintained with the WWAN while connected to the trusted WLAN. In some cases, the connection used to maintain the attachment may be an internet protocol (IP) multimedia subsystem (IMS) connection. Alternatively, the UE may determine that the WLAN connection is a trusted connection and deactivate the WWAN connection. Should the WLAN become unavailable the UE may reactivate the connection with the WWAN.
Abstract:
Aspects of the disclosure are directed to congestion control in a user equipment in connected mode including upon receipt of a trigger, using a register to determine if a data packet transmission has been initiated by an application associated with the UE, wherein the UE is in a connected mode; retrieving an Application-specific Congestion control for Data Communication (ACDC) category mapped to the application associated with the UE, wherein a mapping between the ACDC category and the application is performed a priori to a transition to the connected mode; retrieving at least one access control parameter based on the ACDC category; and determining if the application is allowed to perform the data packet transmission based on the at least one access control parameter.
Abstract:
Certain aspects of the present disclosure propose techniques for Evolution-Data Optimized (EVDO) session handling during inter radio access technology (IRAT) mobility with support for S101 signaling interface. A UE may determine a mobility scenario for transfer of the UE among a first cell and a second cell, while the UE has an EVDO session. The UE may further determine whether pre-registration of a UE EVDO session is allowed via an S101 signaling interface. The UE may perform a procedure related to the EVDO session based on the determined mobility scenario and whether the pre-registration is allowed or not.
Abstract:
Systems and methods are disclosed for supporting, in a device, Wireless Local Area Network (WLAN)-Wireless Wide Area Network (WWAN) mobility, data offload, and simultaneous usage of different access networks on a per Access Point Name (APN) basis. The device determines an access network among WWAN and WLAN for a data stream having an APN. The device additionally hands off the data stream according to the determined access network, while maintaining Internet Protocol (IP) continuity. The device further routes packets of the data stream to at least one of a protocol stack or interface for the determined access network in accordance with an inter-system routing policy (ISRP).
