Abstract: In a wireless communication system, a method and apparatus of communicating between at least one base station and a core network is claimed. Signaling messages and voice streams are transported using packet-switched protocols (IP). A CIC field (Circuit Identity Code) is used to identify at least one VoIP streams. The CIC field may be interpreted as a UDP port number for the voice over IP stream. Also, a synchronization source or contributing source filed of a RTP header may be used as the CIC field.

Abstract: A system and method are provided for mobile Internet Protocol (IP) addressing, in a multi-mode wireless communications access terminal (AT). The method provides an AT with an IP address (ATA), and a care-of-address (CoA) in each of a plurality of networks. In one aspect, the AT selects a first network for transmission, from the plurality of networks. The AT sends an IP packet to a correspondent node (CN) via a first mobile node (MN) external device. Regardless of the network selected, the AT is able to use the ATA as a source address. Sending the IP packet to the CN may include creating a tunnel between the first MN and the HA. The IP packet is sent to the HA using the first CoA as a tunnel source address, and the HA sends the IP packet to the CN using the ATA as the source address.

The processor is further configured to maintain an indicator relating to the portion of the data in the queued packet that remains to be transmitted.

Abstract: A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.

Abstract: Systems and methodologies are described that facilitate mitigating a hidden node condition in a wireless mesh network wherein nodes utilize a request-to-send/clear-to-send (RTS/CTS) protocol in conjunction with an asynchronous hybrid automatic repeat request protocol. For instance, a node may contend for a set of subcarriers by sending an RTS signal over the desired subcarriers, and may receive a CTS signal over the contended subcarriers, wherein the CTS signal indicates which subcarriers the node may transmit data over. If another node has won the contention for a particular subcarrier, requesting node may adjust a power level at which it transmits an RTS or a data packet in order to permit the requesting node to utilize the subcarrier without interfering with the winning node.

Abstract: Computer data is transferred between a CDMA radio access network and a GSM core infrastructure using a switch that acts on the CDMA side as a packet data serving node (PDSN) element and on the GSM side as a serving GPRS service node (SGSN) element. Switching message sequences and protocol stacks are disclosed.

Abstract: Systems and methods are described that facilitate performing interference management techniques between sending and receiving nodes in order to provide minimum transmission rate guarantees. Carrier-to-interference ratio (C/I) may be controlled by employing specialized resource utilization messages (RUMs), the number and rate of which may be governed by a “token bucket” mechanism. For instance, a maximum token bucket size may be defined for a node, which describes the maximum amount of data that may pass through the node at a given time. A current number of tokens in the node's bucket may be evaluated and compared to a threshold value, and RUMs may be transmitted by the node as long as the current token number is greater than the predefined threshold value. Tokens may additionally be deducted from the node's bucket for successful data transmissions, thus providing a dynamic interference control mechanism.

Abstract: Systems and methods are described that facilitate evaluating conditions of nodes (e.g., access points, access terminals, etc.) in a wireless communication environment to determine a level of disadvantage for a given node relative to other nodes. A first node may receive a resource utilization message (RxRUM) and may determine a level of disadvantage for a node that sent the RxRUM. The first node may then compare its own level of disadvantage to the sending node in order to permit a determination of an appropriate course of action in response to the RxRUM.

Abstract: Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

Abstract: Systems and methods are described that facilitate data communication in a wireless communication environment. According to various aspects, a node, such as an access point or an access terminal, may determine a number of channels over which it will transmit a communication signal. The node may then select channels based on whether the channels are available or unavailable, wherein available channels are preferentially selected over unavailable channels. The node may then transmit a signal over the at least one of the selected channels.

Abstract: Systems and methods are disclosed that facilitate dynamically adjusting a number of resources, such as channels, frequencies, tones, etc., occupied by a node (e.g., an access point, and access terminal, etc.) in accordance with various aspects. A level of service experienced at the node may be determined, and a resource utilization message (RUM) may be generated if the level of service is at or below a predetermined threshold level (e.g., an acceptable level of service). The RUM may indicate a number of resources selected by the node for subsequent use, and may be transmitted to one or more other nodes.

Abstract: A telecommunications system includes an infosphere having a mobile telephone. A first telecommunications device may request to be added to the infosphere by sending a request to a registry server. In response to the request, the registry server adds the first telecommunications device to the infosphere by creating a network address for the first telecommunications device, the network address being related to the telephone number of the mobile telephone. In some embodiments of the telecommunications system, the registry server may require authorization from a second telecommunications device in the infosphere before adding the first telecommunications device to the infosphere.

Abstract: A general global gateway (GGG) uses shared secret data to authenticate between a CDMA network and a GSM network such that a mobile station having a subscription in a GSM network can roam into a CDMA network and be authenticated to use the CDMA network without having a complete ANSI-41 subscription. The goal of authenticating a GSM subscriber in an ANSI-41 network using GSM authentication credentials is achieved by substituting encryption key Kc as SSD-A in the standard ANSI-41 computation of AUTHR using a CAVE algorithm.
