A second access network receives a service request from the wireless communication device and transfers a buffer initiation signal to the core network interface. The second access network establishes a wireless link to the wireless communication device and transfers a packet connection request to the core network interface. The core network interface receives more user data for the wireless communication device, buffers the additional user data responsive to the buffer initiation signal, and transfers the user data to the first access network for delivery to the device. The core network interface establishes a packet connection to the wireless communication device and transfers the buffered user data to the device over the second access network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buffering user data in a core network interface for delivery over a wireless access network","description":"In a communication system, a core network interface receives user data for a wireless communication device and transfers the user data to the device over a first access network.
