Abstract: Techniques to forward unsolicited messages from an (IS-2000) CDMA radio network via an HDR radio network to an access terminal. A session is first established between the access terminal and the HDR radio network. During session establishment or thereafter, the access terminal indicates to the HDR radio network an interest in receiving unsolicited messages from the CDMA radio network. The access terminal typically also registers with the CDMA radio network. Thereafter, unsolicited messages can be sent from a mobile station controller (MSC) to the HDR and CDMA radio networks, or sent from the MSC to the CDMA radio network, which then forwards the messages to the HDR radio network. The HDR radio network encapsulates the unsolicited messages and sends the encapsulated messages to the access terminal. The forwarding of unsolicited messages allows the CDMA radio network to communicate with an access terminal.

Abstract: FIELD: digital data transmission by expanding sequential numbering range for selective retransmission protocol. SUBSTANCE: according to one example of implementing this invention data frames are transmitted including eight-bit sequential number and single-bit retransmission flag. Single-bit retransmission flag points to whether frame is newly transmitted or retransmitted due to failure of first transmission. Transmission system maintains twelve-bit sequential number referred to as long sequential number incorporating eight-bit sequential number transferred with each frame and four-bit expansion number. Long sequential number is transferred in control frame and eight-bit one, in data frame. EFFECT: ability of expanding sequential number range without modifying bit number for sequential number. 9 cl, 8 dwg

Abstract: A control system (900, 1100) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. Generally, various aspects of the invention provide for efficient use of communication resources in a communication system (100) by efficiently controlling delay of a TCP acknowledgment message of reception of data from one communication protocol layer to another. Moreover, the delay of the TCP acknowledgment message and the message may be controlled to effect an efficient and consistent flow of data from a source end to a destination end , in particular, in case of encrypted communications.

Abstract: Method and apparatus for data packet communications in a communication system. Packets are received at a gateway having an Internet Protocol (IP) destination address and Network Access Identifier (NAI). The gateway maps the received NAI to a local network, such as supported by a Network Address Translator (NAT). The gateway then converts the destination address to a NAT address of the local network. The gateway also adds a port number that allows the NAT to identify the target recipient. The mapping within the gateway is created and maintained as Mobile Stations send registration requests upon arrival within a local network. In one embodiment, the registration request is a Session Initiation Protocol (SIP) registration.

Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

Abstract: The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted.

Abstract: A method for detecting delayed data frames in a transport function includes the steps of comparing a frame sequence counter with a predetermined threshold value, detecting a delayed frame if the sequence counter exceeds the threshold value, and processing the detected delayed frame accordingly. In an RLP data transport protocol, the delayed frame may be processed as a retransmitted frame. The threshold value may be proportional to the maximum number of frames sent in a given bundle times the maximum delay, in units of frame intervals, between frames sent simultaneously over the air in the same frame interval.

Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated key is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.
