摘要： Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption. Acquisition attempts may be performed in a “ping-pong” manner to improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.

摘要： A system and method for determining 1xEV-DO availability for a packet data call in a wireless device is presented. When the wireless device receives a request to initiate a packet data call, the device determines if it currently has access to a preferred 1xEV-DO channel. The determination can be made by consulting a 1xEV-DO availability list stored in persistent memory on the wireless device. If available, the wireless device originates the packet data call on the 1xEV-DO channel. If the device is using a CDMA system that has 1xEV-DO channels but the availability or usability of those channels are unknown, the device polls the signal strength on the 1xEV-DO channels to determine the best 1xEV-DO channel to use for the packet data call. If no 1xEV-DO channel is available or if none of the available 1xEV-DO channels are usable, then the device originates the packet data call on a CDMA channel.

摘要： The access terminal is configured to wirelessly send to a data system a request that the data system assign an access terminal identifier (ATI) to the access terminal. The access terminal delays transmission of the request until after a user of the access terminal has employed the access terminal to request a packet data service from the data system. In some instances, the data system is an Evolution, Data Only (EV-DO) system and the access terminal identifier (ATI) is a Unicast Access Terminal Identifier (UATI) generated by the Evolution, Data Only (EV-DO) system.

摘要： One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.

摘要： A wireless device receives a request to originate a data call, e.g., from the user or a higher layer application. If origination control is not to be applied, then the wireless device originates the data call immediately. Otherwise, the origination of the data call is controlled based on prior data call origination attempts that are applicable to the data call. For example, the wireless device may originate the data call immediately if (1) the most recent origination attempt was successful or (2) the most recent origination attempt was unsuccessful but a predetermined time period has elapsed since this unsuccessful origination attempt. If the most recent origination attempt was unsuccessful and the predetermined time period has not elapsed, then the wireless device may (1) wait until this predetermined time period elapses and then originate the data call or (2) reject the data call.
摘要翻译：无线设备例如从用户或更高层应用接收到发起数据呼叫的请求。如果不应用发起控制，则无线设备立即发起数据呼叫。否则，根据适用于数据呼叫的先前的数据呼叫发起尝试来控制数据呼叫的发起。例如，如果（1）最近的发起尝试成功，或者（2）最近的发起尝试不成功，但是从该不成功的发起尝试起经过了预定时间段，则无线设备可以立即发起数据呼叫。如果最近的发起尝试不成功并且预定时间段没有经过，则无线设备可以（1）等待，直到经过该预定时间段，然后发起数据呼叫，或者（2）拒绝该数据呼叫。

摘要： Embodiments disclosed herein relate to methods and systems for reporting and compiling connection failures in wireless communication systems. In an embodiment, when an access terminal experiences a connection failure (e.g., an unintended one), the access terminal may generate a connection failure record associated with the event, and send a message containing the connection failure record to an access network it has since established the connection. The access network may send a message containing a connection failure report acknowledgement (ACK) message to the access terminal, upon reception of the connection failure report message. The network operators may use the connection failure records thus compiled to identify problematic spots in the system and improve the quality of service.

摘要： Disclosed is a method for storing an identifier in a first station having a secure non-volatile data store protected by cryptographic data, an identifier flag for indicating that the identifier has been written to the secure data store, and an authenticated trust agent that prohibits writing of an identifier to the secure data store if the identifier flag is set. In the method, the identifier is written to the secure non-volatile data store, wherein the identifier written to the secure data store is encrypted using the cryptographic data. The identifier flag is irreversibly set after writing the identifier to the secure data store so that the trust agent prohibits another write of an identifier to the secure data store.
