  • Publication number: 20240349366
    Abstract: A method and apparatus for session management in a wireless network are disclosed. For example, a user endpoint (UE) device, sends a request for a session internet protocol (IP) address assignment using an interface IP address, configures the UE device with the session IP address, provides to a controller an association of the interface and session IP addresses, and receives packets addressed to the session IP address via an access network entity associated with the interface IP address. In one example, a controller receives an association of an interface IP address with a session IP address from an attached UE device, provides to a network node an update on a route to reach the session IP address through the interface IP address, identifies an active interface IP address to receive packets, and configures an open flow switch or router for routing the packets towards the active interface IP address.

  • Publication number: 20240314636
    Abstract: Disclosed herein are systems and method for providing quality of service to data streams transmitted via a single protocol stream. A scheduler of a sender can receive profiles corresponding to streams of data generated by an application of the sender. The scheduler can receive, from a receiver receiving the streams of data, congestion information of some the streams of data. The scheduler can determine, according to the congestion information and the profiles, a priority of a first stream with respect to a second stream of the streams of data, for a single protocol stream. An assembler of the sender can generate a plurality of packets of the single protocol stream using first packets of the first stream and second packets of the second stream in accordance with the priority. The sender can transmit to the receiver, the single protocol stream comprising the plurality of packets.

  • Publication number: 20240297915
    Abstract: Connecting user equipment (UE) to an application can be managed based on UE movement and location. During data session between UE and application, a communication management component (CMC) associated with anchor network component (ANC) or serving network component (SNC) determines UE location, and connects UE to the ANC and SNC, which enables access of the application via a data network associated with ANC. As UE moves, CMC tracks UE movement and communication conditions. If, when UE is at second location, a communication condition breaches threshold level, CMC determines whether interruption of the data session is permitted. If not, CMC determines whether there is a local SNC in proximity to second location. If there is, CMC can switch UE from SNC to local SNC, which can access local application content via local data network associated with application. If interruption permitted, UE deactivates and reactivates to connect to local ANC.

  • Patent number: 11825529
    Abstract: Disclosed herein are systems and methods for facilitating wireless communication of a wearable device. In one aspect, a wireless device receives a paging message from a cellular network, via a wireless link between the wireless device and a companion device. The paging message can be received while a cellular modem of the wireless device is operating in reduced power mode and not registered with the cellular network, and the companion device is registered with the cellular network. The wireless device can transition the cellular modem from the reduced power mode to an active mode in response to receiving the paging message via the wireless link with the companion device. The wireless device can register with the cellular network after the modem has transitioned to active mode, to establish a cellular link directly with the cellular network.
