Abstract: A network node, method, and mobile terminal for providing circuit-switched (CS) voice calls to a mobile terminal operating in a packet-switched (PS)-only network. A control node such as an EPC node in an SAE/LTE PS-only network is modified to mimic the messaging functionality of a Serving GPRS Service Node (SGSN). The EPC node is connected to an MSC/VLR in a CS network through a Gs interface. The EPC node registers the terminal with the MSC/VLR and provides a VLR TMSI to the terminal. When the MSC/VLR receives an incoming CS voice call for the terminal, the MSC/VLR notifies the EPC node, which sends a paging message to the terminal. To set up the CS voice call, the terminal sends a paging response directly to the MSC/VLR.

Abstract: A mobile station having a Voice-Over-Internet-Protocol client sends a message proposing a frame packing and frame repeating parameter set (1001). The called client may either accept the proposal or offer a revision (1003). If accepted the VoIP call is established (1009). If a revised proposal is received, it is determined whether the parameters are acceptable (1005). If not the call is declined (1007). If acceptable the call may proceed (1011). Both clients may then monitor network conditions (1013) and propose revisions to the parameters as conditions change. In this way, the VoIP application layer compensates for physical and Medium Access Control (MAC) layer inefficiencies in transporting the small frames used for audio data transfer for VoIP.

Abstract: The present invention provides methods for performing payload header suppression (PHS), expansion, and verification in hardware. A PHS verify circuit reads a data packet until it reaches the location where the first byte must be compared to PHS rule verify bytes. Next, all the relevant bytes in the payload header are compared to the PHS rule verify bytes obtained from a payload header suppression rule mask. Upon completion of the compare, a flag is generated to a PHS suppress circuit indicating that verification has passed or failed. For payload headers passing the verification process, the payload header suppress circuit examines the payload header suppression mask to identify one or more bits in the payload header for which an associated byte string is to be suppressed. Next, the associated byte string for each of the identified bits are suppressed to generate a suppressed packet payload header. Finally, a payload header suppression index is added to the suppressed packet payload header.
