    Abstract: A method and data structure for preventing the misconcatenation of partial packets when an even number of packets are lost over the network. A channel identifier code is added to the head of a remainder partial packet to allow the remainder partial packet to reassembled with a prior partial packet having the same channel identifier code. The method includes the steps of determining whether each packet will be divided into a first partial packet and a remainder partial packet at an ATM cell boundary, adding a CID at the beginning of each remainder partial packet, assembling the first and remainder partial packets into ATM cells, transmitting the ATM cells, receiving the ATM cells, verifying whether a first partial packet and a remainder partial packet in the received ATM cells have the same CID and assembling the first partial packet and the remainder partial packet into a single packet when the CIDs match. The method may also includes the steps of discarding the first and remainder partial packets when the CIDs do not match or sending the first partial packet to a user identified by the CID for the first partial packet and the remainder partial packet to a user identified by the CID for the remainder partial packet. The CID comprises a one byte code. The data structure for the ATM cell includes a header and a payload assembled to the header, the payload comprising at least one packet, wherein the at least one packet comprises a remainder partial packet having a channel identifier code attached thereto to identify the user for the remainder partial packet.

    Abstract: A method and system supports multilevel QoS (Quality of Service) in transferring a plurality of packets from a local peer entity to a remote peer entity of a communication system, such as a mobile environment using AAL2. During AAL2 Negotiation Procedures (ANP), QoS requirement of each user is obtained either from the user or a computed based on the call setup and is recorded in a ANP memory. After a successful call request negotiation and after a corresponding packet is received by a AAL2 service module, the packet's QoS recorded in the memory is checked. Based on the QoS, the packet is placed into a queue of the AAL2 service module with the same QoS such that a plurality of packets having the same QoS are grouped into the same queue. The packets are transferred from the local peer entity to the remote peer entity based on different QoS requirements.

    Abstract: A method and apparatus to provide encryption and authentication of a mini-packet in a multiplexed real time protocol (RTP) payload. Mini-packets are assembled into a payload wherein each mini-packet includes an associated mini-header for ensuring proper processing of each mini-packet. Padding is added to mini-packets when the mini-packets are encrypted to insure each mini-packet is an integral multiple of a predetermined block size. Padding for each mini-packet is determined according to p=n−k*floor((n−1)/k), wherein p is the amount of padding added to each mini-packet, n is the actual data size, and k is the block size. The padding added to the data for each packet comprises p−1 units of padding and a final padding unit for indicating the amount of padding. An authenticator may also be added to each mini-packet. A length indicator is set in each mini-header for indicating a total length of the mini-packet including the authenticator. The authenticator may then be removed based upon knowing a type of authentication used for generating the authenticator.

    Abstract: A knowledge-based connection admission method is disclosed for efficient multiplexing of data and speech over AAL2. The method uses a knowledge-based technique to decide when and what type of data traffic will be multiplexed with speech traffic in ATM Adaptation Layer 2 (AAL2) environment. The knowledge-based connection technique supports low bit rate and delay sensitive applications such as mobile telephony in an ATM environment by maximizing the use of available bandwidth. The method includes monitoring ATM cells for a AAL2 connection, determining whether the ATM cells contain unused bytes and multiplexing data traffic with speech traffic on the AAL2 connection when the data meets a predetermined set of requirements. The method determines whether the data traffic requires a bandwidth that exceeds a bandwidth provided by the unused bytes and multiplexes the data traffic with the speech traffic when the bandwidth required by the data traffic does not exceeds the bandwidth provided by the unused bytes and prevents the multiplexing of the data traffic with the speech traffic when the bandwidth required by the data traffic exceeds the bandwidth provided by the unused bytes. The unused bytes represent silence periods during speech traffic. System observations are gathered and processed with prior knowledge about the system. Based upon the processing, whether the data traffic is suitable for multiplexing with speech traffic is determined and the data is multiplexed with the speech traffic when the data traffic is determined to be suitable for multiplexing with speech traffic in the unused bytes of the speech ATM cells.
