Abstract:
In a system including a resource (100) which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.
Abstract:
The present invention is a novel method and apparatus for providing transparent mobility of an entity within a network. The present invention allows a given entity, which has a communication path set up between it and a peer entity, to move from one location to another, without informing the peer entity of this movement, and without having the communication path broken. The present invention is applicable to decentralized networks using the IP protocol, and is particularly applicable on networks wherein it is desired that the mobility mechanism neither introduces latency nor decreases the available bandwidth of the network. In the present invention, neither is latency increased nor is bandwidth utilization increased, as is done in other mobility models. Additionally, the present invention utilizes standard protocols that are widely available from a plurality of equipment manufacturers on a variety of platforms. Thus, the present invention provides a very cost-effective model for network providers that need to support transparent mobility within their network.
Abstract:
A system provides wireless data service. The system includes a wireless modem (42) configured to be coupled to a terminal equipment unit (40) over a wireline broadcast medium (56). A network unit (58) is coupled to the wireless modem (42) over a wireless link connection. A network remote server (60) is coupled to the network unit (58). The network remote server (60) provides IP address information in response to terminal equipment unit address request messages for terminal equipment units (40) coupled to the network unit (58). In addition, a local server (52) is couple to the wireless modem (42). The local server (52) provides IP address information in response to terminal equipment unit (40) address request messages from terminal equipment units (40) coupled to the wireline broadcast medium.
Abstract:
Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.
Abstract:
Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.
Abstract:
Methods and apparatus for communicating packets from a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to recover a tunneled route protocol packet. Information to be communicated to the access terminal from the remote access node assembly by way of the serving access node assembly is subject to two levels of radio link protocol (RLP) processing operations. The first level of RLP processing being performed by the remote access node assembly. The second level of RLP processing being performed by the serving access node assembly. The access terminal, in recovering information performs the inverse of the two levels of RLP processing.
Abstract:
Un procedimiento de comunicaciones inalámbricas, que comprende: el control de una primera red (106) de conmutación de paquetes, "PS", de acuerdo con una primera interfaz radio; el envío de una solicitud de filtrado a la red PS para permitir que solo determinados tipos de mensajes asociados con una red (114) de conmutación de circuitos, "CS", sean transmitidas sobre la primera interfaz radio por la red de PS, estando la red de CS asociada con una segunda interfaz radio diferente de la primera interfaz radio; y la recepción de uno o más mensajes procedentes de la red de CS por medio de la primera interfaz radio de acuerdo con la solicitud de filtrado.
