Abstract: Active sessions and dialogs may be moved between connections and P-CSCFs. For example, in some embodiments either new bindings may be created with a different connection for a Public User ID or the UE may re-register one or more specific bindings for a Public User ID from one connection to another. The capabilities improve service continuity when handing over between IP-CANs. FIG. 13 illustrates exemplary messaging for moving bindings to a new connection for a Private User ID between UE (1305) and P-CSCF (1307) when the UE (1305) is in a visited IP-CAN, that is, visited network (1303). The UE (1305) invokes the unprotected global seamless re-registration of the embodiments via an unprotected initial registration procedure wherein the UE (1305) includes a “seamless-ims” parameter in the Require and Proxy-Require headers of the REGISTER request (1313). The S-CSCF (1311) provides the capability to subsequently re-register bindings over new or existing connections.

Abstract: A method and device for transmitting at least one short messaging service message to at least one wireless device are disclosed. The method comprises receiving at least one short message service message request associated with a short message service message. The short message service message is destined for reception by a wireless device (106). Prior to receiving the request, a short message service center (114) determines if a wireless device (106) is registered with a registrar (210) associated with a session initiation protocol network for communicating over a packet data network (102). The short message service message is transmitted to the wireless device (106) through the session initiation protocol network communicating over the packet data network (102) in response to the request and with the determination that the wireless device (106) is registered with the registrar (210).

Abstract: State machine diagram (300) illustrates inactive connection (303) management wherein all bindings are deregistered, but active sessions remain. The mobile station may, re-register the connection (309), to stop the Linger Timer (305) and return the connection to the active state (303) before timeout, or otherwise before the inactive connection is terminated. Otherwise, the Linger Timer may be stopped when the last active session is moved to a different connection, or released (311). If the Linger Timer times out (315), any active sessions will be released without the explicit action of the mobile station. In the active state (303), if all bindings are deregistered and no active sessions are present, the connection may be terminated immediately as in (313), without invoking the Linger Timer. Thus, the mobile station has an opportunity to take action regarding remaining sessions, such as releasing or refreshing on a different but active connection.

Abstract: A system and method for establishing a secure and authenticated session layer path between user equipment (102) and a security proxy (112), such as a serving call session control function (116). A communications session is established at a user equipment node (102), prior to registering with the security proxy (112). The user equipment (102) subscribes, through the communications session prior to registering with the security proxy (112), to an event package from the security proxy (112). A secure and authenticated session layer path (426) is established, based upon the subscription, through the communications session from the user equipment node to the security proxy (112) and therefore the serving call session control function (116). A session initiation protocol session (442) is originated, at the user equipment node (102), over the secure and authenticated session layer path (426) based upon authentication provided by the secure and authenticated session layer path (426).

Abstract: A UE (200) may establish various IMS Connections via various Access and Transport Networks (211). Each IMS Connection is associated with a specific contact address and all IMS connections are associated with a single specific Private User ID (229). Also various IMS connections may be established through different or identical P-CSCFs. For example, active IMS Connection (213) is associated with contact address 1 (203) and P-CSCF #1 (215), while IMS Connection #2 (217) is associated with contact address 2 (205) and P-CSCF #2 (219). All IMS connections shown in FIG. 2 are via IPsec and are connected to S-CSCF (227). Therefore, at S-CSCF (227) the UE (200) is associated with one Private User ID (229) based upon the UE (200) ISIM (201). Thus in accordance with the embodiments, sessions may be moved between IMS connections and P-CSCFs which facilitates handoffs between various Access and Transport Networks (211).

Abstract: Multimedia IMS communications are established by matching callee capabilities with caller preferences and identifying a URI parameter in response thereto. When a session initiation protocol (SIP) request identifying caller preferences for an internet communication session and an identified callee is received (602), a determination is made of whether the identified callee is a registered address of record (AOR) or not (604). If the identified callee is a registered AOR (604), a uniform resource identifier (URI) parameter and a globally routable user agent URI (GRUU) associated with callee capabilities are identified (608, 612, 614). The URI parameter is used to create a modified SIP including the URI parameter (616) for sending (618) to an IMS enabled wireless communication device (120).

Abstract: An integration system using multiple types of MSCs (12, 14) has been provided. An access request from a mobile station (22, 24, 26) is first determined (36) whether it is associated with a second type of MSC. If so, the access request is routed (38) to a MSC of the second type. Otherwise, it is determined (42) whether the access request is a registration, and if so, the access request is also routed (38) to a MSC of the second type for the registration processing. At the registration process, it is determined (82) whether the access request should be associate with the second type of MSC, and if so, an association as such is assigned (86) between the mobile station and the second type of MSC.

Abstract: A system controller (10) having a first mode of operation to repage a wireless mobile station in a multi-zone wireless communication system (11). The system controller (10) accesses a location register (12) to obtain a zone location corresponding to a wireless mobile station. The system controller (10) then uses the transmission resources of the zone location to facilitate sourcing a wireless communication with the wireless mobile station. If the wireless mobile station does not respond, the first mode of operation for repaging the wireless mobile station includes the system controller's (10) accessing the location register (12) to obtain a second zone location and using the transmission resources of only the second zone location to source a wireless communication to the wireless mobile station.

Abstract: Various embodiments are described to address the need for providing substantially reduced PTT call setup times and more efficient wireless bandwidth utilization for PTT sessions utilizing an IP-based protocol. The use of non-IP messaging between an originating MS (101) and PCF (131) and a target MS (102) and PCF (132), the use of IP-based messaging between the PCFs, the use of access channel signaling by the originating MS, and the generation of SIP responses by a target PCF on behalf of the target MS are described. Embodiments incorporating some or all of these protocol changes, can provide either, or both, reduced end-to-end call setup time for PTT as it presently exists in IS-2000 systems or reduced bandwidth consumption.

Abstract: Disclosed is a method of producing gapped ferrite toroids without the necessity of machining. This allows for the highly efficient production of tightly controlled energy storage magnetic components and stable inductors. Composite toroids of the invention have a wide range of applications, and could be used as substitutes for more costly and less operationally efficient magnetic components. This invention provides a method of producing composite toroids that include a nonmagnetic gap, by utilizing a layer-forming method, such as tape casting, and subsequently co-firing a monolithic composite magnetic and non-magnetic ceramic structure produced by stacking the layers. The toroids are punched from the stacked layers prior to final firing. This novel method provides a means for producing very well controlled gapped structures.

Abstract: The variable pedal ratio brake actuating mechanism has a first lever pivotally mounted on an arcuately movable brake pedal arm. The lever is guided pivotally by a pivot control lever which pivots about a fixed point at one end and is connected at its other end to a first pivot on the first lever spaced from the first lever pivotal mount. An output member is pivotally connected to a second pivot on the first lever spaced from the first lever pivot mount and first pivot. The first lever is moved translatorily and also arcuately about its pivotal mount as the brake pedal arm moves in the brake actuating direction to change the effective pedal ratio.

Abstract: A hydraulic power brake system has a pump driven through a variable torque magnetic clutch by an engine-drive pulley. A rheostat controlled by movement of the brake booster push rod varies the amount of current to the clutch to control the torque transmitted to the pump. The pump pressure output varies directly with clutch torque. Pump pressure is delivered to a closed center hydraulic booster. The pump does not operate when no braking effort is required.

Abstract: A well packer or layer-separating device adapted to seal off a stringer against a deep-well casing comprises a polished sleeve against a shoulder at the upper end of which a sealing ring is compressible to seal the device against the inner wall of the casing. Below this seal there are provided two rows of keys engageable with the casing to hold the device in place. The upper row is forced outwardly by a downwardly divergent wedging member coupled to an anchoring sleeve which is held by an upper locking device against the polished sleeve. The lower end of the polished sleeve is formed as a piston which cooperates with a cylinder driving an upwardly converging wedge member beneath the lower row of keys and, via shear screws causing the anchor sleeve to ride upwardly.

Abstract: A hydraulic power brake booster powered by power steering gear pump pressure and utilizing an open-center valve so that fluid flows through the booster without pressure reduction when the booster is not activated. The booster has two power chamber sections, both being pressurized at the same time under normal brake operation. However when the brakes are applied very fast, a high rate of pressure increase occurs in one chamber but not in the other due to a flow restriction between the two chambers. The booster piston assembly will therefore move in the brake applying direction more quickly than it would if the pressure fluid should be acting on the full power piston diameter since less displacement is momentarily required to build up the necessary pressure. The chamber section with the slower pressure buildup rate will increase in volume and be maintained full of fluid by a check valve arrangement extending through the piston and connecting with the low pressure side of the piston.
