Abstract: A method for allocating resources in a communication system having a plurality of base stations each serving multiple user stations, the method comprising: receiving, at a first base station, service requests from a plurality of user stations; dynamically allocating resources at the first base station including assigning a transmission rate for transmission of information between the first base station and each user station independently of allocation of resources by other base stations, based on a set of criteria including a set of requirements associated with each service request and interference generated by other base stations in the communication system, wherein the transmission rate assigned to each user station is determined to optimize a sum of all transmission rates assigned by the first base station to the plurality of user stations based on the set of requirements associated with each service request and wherein higher transmission rates are assigned to user stations which are relatively closer to the first base station; and transmitting rate assignment information from the first base station to the plurality of user stations.

Abstract: A method and system provides for efficient data throughput by avoiding unnecessary data sub-packets transmission while not missing new data packets. The method and system distinguishes between a sub-packet for a current data packet and a sub-packet for a new data packet by assigning different codes to them. When a currently received sub-packet and a previously received sub-packet for a previously decoded data packet have equivalent codes, the remote station ends (506) an acknowledgement signal to the base station, preventing unnecessary sub-packets transmission. When the currently received sub-packet and the previously received sub-packet have different codes, the remote station sends (510) an acknowledgement signal, if the remote station can decode the new packet from the current sub-packet. Otherwise, the remote station sends (516) a negative acknowledgement signal to the base station, and requests more sub-packs for the current packed if the limit on number of transmission for currently received sub-packet has not reached.

Abstract: Embodiments disclosed herein relate to a new set of radio link protocols (RLPs) configured to provide for efficient data transmission in a multi-link communication system. In an embodiment, an upper-layer packet is segmented into link-layer packets to be transmitted over a plurality of communication links, each including a first sequence number in accordance with a predetermined order. A second sequence number is further added to each link-layer packet to be transmitted for the first time. The second sequence number is configured to be in a sequence space associated with a particular communication link, and may be used for detection of missing packets.

Abstract: Methods and apparatus for authorizing an access terminal (AT) requesting a service provided by an entity in an access network are disclosed. After being authorized for a communication session with the access network, the AT addresses an inquiry to a domain name server (DNS) for a contact of a service selector (SS) administering the desired service. A controller in the access network (BSC/PCF) routs the inquiry to and returns a response from the DNS. The AT then addresses a service query containing the AT's capabilities to the SS. The BSC/PCF directs attributes allowing the SS to authorize the service. Upon the SS's acknowledgement of the attributes, the BSC/PCF forwards to the SS the service query. Upon authorization, the SS notifies the BSC/PCF, and if the AT is authorized, selects in accordance with the AT's capabilities an appropriate service provider (SP) to provide the service.

Abstract: In a channel structure for use in communication systems, two sets of physical channels, one for the forward link (50) and another for the reverse link (52), are utilized to facilitate communication of a variety of logical channels. The physical channels comprise data and control channels. In the exemplary embodiment, the data channels comprise fundamental channels which are used to transmit voice traffic, data traffic, high speed data, and other overhead information and supplemental channels which are used to transmit high speed data. The fundamental channels can be released when the remote stations are idle to more fully utilize the available capacity. The control channels are used to transmit paging and control messages and scheduling information.

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. One embodiment provides link layer content encryption. Another embodiment provides end-to-end encryption.

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.
