Abstract:
1. An apparatus comprising: a processor configured to send first authentication credentials via a Point-to-Point Protocol (PPP) link to a Packet Data Serving Node (PDSN), to receive an indication of successful authentication for a first data service based on the first authentication credentials, to receive a request for a second data service different from the first data service and second authentication credentials for authenticating to the second data service from a terminal device, to send the second authentication credentials via the PPP link to the PDSN in response to the request for the second data service while the first data service is ongoing, wherein the sending of second authentication credentials comprises sending a Configure-Request packet with the second authentication credentials to initiate authentication for the second data service, receiving a Challenge-Handshake Authentication Protocol (CHAP) Challenge packet from the PDSN in response to the Configure-Request packet, and sending a CHAP Response packet with the second authentication credentials to the PDSN, and to receive an indication of successful authentication for the second data service based on the second authentication credentials; and a memory coupled to the processor, wherein the processor is configured to receive inbound packets from the PDSN for the first and second data services, to pass inbound packets for the first data service up a protocol stack at the apparatus, and to forward inbound packets for the second data service to the terminal device.
