Abstract:
A home agent ( 104, 108 ) and a foreign agent ( 110, 114 ) in a wireless communication system ( 100 ) establish ( 202 ) a special communications channel ( 140-154 ) between themselves, the special communications channel dedicated to messages addressed to multiple mobile nodes. The home agent then detects ( 206 ) whether a message received by the home agent is addressed to multiple mobile nodes. When the message is addressed to multiple mobile nodes, the home agent sends ( 208 ) the message to the foreign agent through the special communications channel.

Abstract:
Fixed network equipment associated with a given private branch exchange provides, and a mobile communication device receives, information that corresponds to compatible interoperation with that private branch exchange, including, for example, a plurality of identifiers including a logical identifier that corresponds to compatible interaction with the private branch exchange. Thereafter, when seeking facilitation of services via that private branch exchange, the mobile communication device can use that logical identifier.

Abstract:
Information regarding the present location of a dual-mode (or multi-mode) mobile station with respect to a plurality of communication systems is timely maintained by facilitating automated contact information modifications via, for example, a mobility management server (30). In a preferred approach, upon receiving a message (11) evidencing the supported presence of a mobile station in a first communication system comprising a wireless wide area network, one automatically responds (12) by modifying such contact information as is retained in a Session Initiation Protocol registrar. Testing (21) can be utilized to assure the propriety of making such alterations and/or deletions.
Abstract:
A wireless communication unit (101) is operable to reformat dialed numbers according to dialing plans for a plurality of communication networks (103, 107, 109), where the unit comprises a transceiver (201) for communicating with any of the plurality of communication networks; a user interface (211) operable to provide a number corresponding to a target unit (102, 102') to be called; and a controller (209) implementing a corresponding method to provide a reformatted number (FIG. 3) corresponding to the number and according to a preference that is specific to the wireless communication unit, where the reformatted number is compatible with a dialing plan for a communication network that will be used to place a call to the target unit.
Abstract:
A method of synchronizing packet rates in a voice over internet protocol system in accordance with one embodiment comprising sending a first parameter from an offering node (100) to an answering node (104), the first parameter indicative of a first rate at which the offering node wants to receive packets (300); and sending a second parameter from the offering node to the answering node, the second parameter indicative of a second rate which the offering node wants to send packets.
Abstract:
A system and method switches between an active call and a call on hold when handing off a mobile station (204) from a Wireless Local Area Network (WLAN) (202). A Handover Starting message is received from a mobile station. The Handover Starting message includes at least one first identifier. A Notification message is also received. The Notification message includes a second identifier. The at least one first identifier is compared to the second identifier and a handover of the mobile station (204) proceeds when a match is determined. Subsequently, the mobile station (204) switches from an active call to a call on hold.
