摘要： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

摘要： Devices and methods are provided for facilitating selection and acquisition of an access point (AP) base station via implementation of a system selection file that may include a preferred roaming list (PRL), a public land mobile network (PLMN) database, or the like. The selection attempts may be limited to specific preferred systems, such as, for example, the AP base station. The system selection file includes identification parameters of the preferred systems. In one embodiment, the identification parameters include at least one of a system identifier (SID) and a network identifier (NID) for a given one of the systems.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network, or any cellular network, and a packet-switched network. During hand-over from the first network to the second network, the sender of packets/frames expands or compresses the packet-switched packets using well-known time-warping techniques. At the receiver end, the received time-warped packets and frames from the second network are appropriately selected so that no unwanted artifacts are introduced during playback.

摘要： 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.

摘要： The disclosure is directed to a mobile communication device that measures characteristics or attributes of a first communications network that vary according to physical location within that first communications network to create a fingerprint, or signature, of a location within the first communications network. When the fingerprint of the current location of the mobile device is created it can be compared to a known fingerprint associated with a second communication network to determine the mobile device's proximity to the second communications network. For example, the first communications network may be a CDMA wide area wireless communication network and the second communications network may be a 802.11 wireless LAN.
