摘要:
There is disclosed a system and method for over the air (OTA) activation of a mobile station in a wireless telecommunications network. During activation, a network OTA processor requests the data configuration of the mobile station. The mobile station may issue a challenge the OTA processor and in so doing transmits a challenge message including certain mobile station parameters and a code lock indicator to the OTA processor. The OTA activation processor determines if a new or first code lock parameter has been forwarded to the OTA activation processor by the network for the code lock indicator. If so, the OTA activation processor includes the first code lock parameter in a challenge message forwarded to the authentication center for processing a response to be validated by the mobile station. If not, the OTA activator forwards the challenge message to the home location register that has previously stored the code lock parameter. The home location register substitutes the stored code lock parameter for the code lock indicator and forwards the challenge message so revised to the authentication center for processing. The authentication center uses a code lock parameter comprising one of the Shared Secret Data Challenge (SSD.sub.-- C) and Shared Secret Data Subsidy (SSD.sub.-- S) security locks. The OTA activation processor is capable of instructing the authentication center to generate new code lock parameters and instructing the home location register to commit to these new operating parameter.
摘要:
There is disclosed a system and method for over the air (OTA) activation of a previously activated mobile station in a wireless telecommunications network. During the new activation, an over the air processor requests the data configuration of the mobile station. The mobile station may issue a first challenge to the over the air processor and in so doing transmits a challenge message including certain mobile station parameters to the over the air processor. The over the air processor then communicates this information to the network authentication center which produces a challenge return message from the certain mobile station parameters and sends the challenge return message to the mobile station. The mobile station validates the challenge return message and if validation is successful the mobile station completes the transfer of mobile station data configuration to the over the air processor. The authentication center uses one of the Shared Secret Data Challenge (SSD_C) and Shared Secret Data Subsidy (SSD_S) security locks not broadcast over the air in the generation of the challenge return message. The authentication center stores the SSD_C and SSD_S for this purpose and is advised by the mobile station on which one of these two parameters is to be used by a Shared Secret Data Select parameter indicator (SSD_Select) forwarded by the mobile station as one of the parameters transmitted in the challenge request. The over the air processor then forwards new operating parameters to the mobile station and requests the mobile station to commit to these parameters. The mobile station may then issue a second challenge to the over the air processor request to commit where the second challenge is handled by the network in a manner similar to the first challenge.

A cellular telephone network includes plural areas each having a plurality of cells. The cells individually supporting certain service capabilities. Inter-exchange messaging is provided for distributing from a second exchange to a first exchange information on the service capabilities supported by a cell serviced by the second exchange. Using the distributed service capability information, the first exchange may identify, in the context of a potential inter-exchange hand-off, whether to request that cells serviced by the second exchange be instructed to make verification signal strength measurements. Furthermore, responsive to received verification signal strength measurement reports, the first exchange screens candidate cells based on the distributed service capability information to select an appropriate target cell served by the second exchange for hand-off.

In connection with instances of inter-exchange hand-off, certain hand-off related parameters assigned to border cells within a first system area are evaluated and considered by the second system area in making the inter-exchange hand-off. To communicate these hand-off related parameters from the first system area to the second system area, a request for the parameters is transmitted from a mobile switching center serving the second system area to a mobile switching center serving the first system area. Responsive thereto, the mobile switching center for the first system area retrieves and delivers the requested parameters for subsequent second system area mobile switching center processing in connection with making the inter-exchange hand-off determination. Alternatively, the mobile switching center serving the first system area acts on its own to retrieve and send certain hand-off related parameters to the mobile switching center serving the second system area for subsequent use in connection with making the inter-exchange hand-off determination.

A system and method of ensuring that a called mobile station's expected service type matches a calling party's service type in a radio telecommunications network in which both voice service and data service are provided. A service code generator in a serving mobile switching center (MSC) generates a service code that indicates the calling party's service type. The service code is sent in a page from the serving MSC to the mobile station, and includes the service code. An expected service code generator in the called mobile station generates an expected service code that indicates the called mobile station's expected service type. The expected service code is sent in a page response from the mobile station to a border MSC that borders the serving MSC. The border MSC extracts the expected service code and sends it to the serving MSC where it is compared with the calling party's service code. If the service codes match, the call is connected to the mobile station. If the service codes do not match, the mobile station is denied access to the radio telecommunications network.
摘要:
A winch assembly for the displacement of a person between a first vertical position and a second vertical position comprising: a winch for displacing a person in a harness between said first and second vertical positions; a first winch attachment means for realizably engaging said harness, said first winch attachment means being attached to said winch for the displacement of a person between said first and second vertical positions; and a second winch attachment means for realizably attaching the winch to an overhead support, the improvement wherein said first attachment means comprises two opposed support arms and displacement means associated with each said support arms whereby at least part of each arms is displaceable between a working extended position for engaging said harness and a non-working retracted position. The winch has a reduced or more compact aspect during non-working periods as well as in the case of a moving of the winch assembly during non-working periods.

A patient lift connector for attaching and detaching a patient lifting bar to a load supporting member in a patient lifting system is described. The connector includes a connector body including a connecting block configured to be fixedly attached to the patient lifting bar. The connector also includes a pin holder coupled to the load supporting member and configured to be inserted through the connector body and into the connecting block, and an attachment latch secured to the connector body and configured to move between an open position and a closed position within the connector body. When the attachment latch moves from the closed position to the open position, the pin holder is allowed to be inserted into the connecting block and thereby allow the lifting bar to be attached to the load supporting member.
