El dispositivo de comunicacion inalambrica se pede utilizar al acceder a la informacion en la memoria, la informacion se relaciona con una primera red de comunicacion. La informacion, junto con una o mas senales de referencia de una segunda red de comunicacion, se utiliza para determinar si el dispositivo de comunicacion inalambrica esta en la cercania de la primera red de comunicacion.
Abstract:
The disclosure is directed to a wireless communication device and method for using the device. The wireless communications device may be used by accessing information in memory, the information relating to the location of a first communications network. The information is based on one or more reference signals from a second communications network and is used to determine whether the wireless communications device is in the vicinity of the first communications network.
Abstract:
Systems and methodologies are described that facilitate device-side access point list management. Blacklists of access points unsuitable for providing network access to a related mobile device can be maintained as well as whitelists of suitable access points. The lists can be managed using an interface provided at the mobile device. In addition, lists can be modified according to provisioned network updates. Also, the lists can be of maximum size such that older entries can be purged upon insertion of newer entries based on a number of factors; timed entry deletion is provided as well. Access points in the lists can be stored and presented according to various identifiers related to the access points.
Abstract:
A mobile device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network is disclosed. A dynamic anchoring mechanism is invoked when the mobile device determines that a circuit-switched call is to be handed over to a packet-switched network.
Abstract:
A mobile station that is configured to facilitate coordination of supplementary services in a centralized fashion may include circuit-switched (CS) domain components that are configured to place voice telephone calls in a CS domain. The mobile station may also include IP multimedia subsystem (IMS) components that are configured to place voice telephone calls in an IMS domain. The IMS components may include a transport component for facilitating communication with an IMS core network. The IMS components may also include a signaling component that is configured to exchange information with a centralized server on the IMS core network via the transport component. At least some of the information that is exchanged with the centralized server may be related to supplementary services for the voice telephone calls in the CS domain as well as the voice telephone calls in the IMS domain.
Abstract:
Techniques to improve the standby time of a station in a wireless network are described. An access point may advertise or convey a maximum listen interval and/or an association timeout supported by that access point. A station may operate in a power-save mode and may wake up every listen interval to receive a beacon and any potential traffic for the station. The station may select a suitable listen interval based on the maximum listen interval. The station may be dormant for a longer duration than the listen interval and may become active at least once in every association timeout in order to keep the association with the access point alive. The access point may also send broadcast and multicast traffic that might be of interest to stations in the power-save mode less frequently and using a special indication message.
Abstract:
Transmission by a first node (102) may be controlled based on a status of a second node (108). The status of the second node (108) may indicate, for example, whether the second node (108) will be communicating with the first node (102). Thus, if it is determined based on the status of the second node (108) that the second node (108) may not be communicating with the first node(102), transmissions by the first node(102) may be temporarily disabled until there is a change in status, and vice versa.
Abstract:
Efficient frequency assignment for mobile terminals in coexisting wireless communication systems is described herein. The coexisting wireless communication systems comprise a macro communication system and a localized communication system. Two prioritized lists are defined, a first list comprising a first entry relating to the macro communication system and the second entry relating to the localized communication system, the first and second entries each listing at least one common frequency. Based on the first list, a mobile terminal uses communication protocols associated with the localized communication system.
Abstract:
Methods and apparatus for determining the quality of a communication link transmitting a specified packet type are disclosed. The methodology includes configuring first packets, which share transmission characteristics with a specific packet type, such as a Voice over IP packet, such that the first packets experience similar communication link treatment as the specific packet type. The first packets are then transmitted over the communication link to a quality monitoring server located near a termination equipment of the particular communication link. Second packets, which are transmitted by the server in response to the first packets, are received and evaluated to determine the quality of the communication link based on characteristics of the second packets. Corresponding apparatus are also disclosed.
Abstract:
An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.
