摘要： Methods, apparatuses, and systems for reducing an occurrence of a Voice over Internet Protocol (VoIP) call from being disconnected in an Evolution Data Only (EV-DO) system are disclosed. The VoIP call is placed on hold and at least one keep-alive packet is issued to prevent a radio link from disconnecting. The at least one keep-alive packet is issued at least while the VoIP call associated with the radio link is on hold and is configured to reset a dormancy timer for the call at one or more network entities.
摘要翻译：公开了用于减少仅在演进数据（EV-DO）系统中断开的因特网协议（VoIP）呼叫的发生的方法，设备和系统。 VoIP呼叫被置于保持状态，并且发出至少一个保持活动分组以防止无线电链路断开连接。至少一个保持活动分组至少在与无线电链路相关联的VoIP呼叫处于保持状态时发出，并且被配置为在一个或多个网络实体处为呼叫重置休眠定时器。

摘要： An operational mode of a terminal is dynamically configured to allow the terminal to receive services of interest to the terminal while potentially conserving battery power. The terminal operates in a first mode (e.g., an HRPD-only mode) and monitors only a first radio network (e.g., an HRPD network) for pages from a first data network (e.g., and IMS network) if all services from a second data network (e.g., an ANSI-41 network) of interest to the terminal is obtainable via the first radio network. The terminal operates in a second mode (e.g., an 1X-HRPD mode) and monitors the first radio network and a second radio network (e.g., a 1X network) for pages from the first and second data networks, respectively, if at least one service from the second data network of interest to the terminal is not obtainable via the first radio network. The terminal may dynamically select the first or second mode.

摘要： A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems. New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system. A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.

摘要： Techniques to efficiently search for a WLAN are described. A terminal receives country information from a wireless wide area network (WWAN), which may be a cellular network or a broadcast network. This country information may be a Mobile Country Code (MCC) that is broadcast by the WWAN. The MCC identifies the country in which the WWAN is deployed. The terminal then performs active scan for a WLAN based on the country information received from the WWAN. For the active scan, the terminal determines a frequency channel and a transmit power level based on the country information. The terminal then transmits a probe request on the frequency channel and at the transmit power level determined based on the country information. The terminal may perform passive scan and/or active scan in accordance with a scan setting.

摘要： Techniques for performing automatic call origination for multiple wireless networks are described. A terminal automatically originates a call and supports fallback in case of call origination failure. The terminal selects the most preferred wireless network for the call based on network availability and network selection information. The terminal attempts origination of the call on the selected wireless network. If the call origination fails, then the terminal may select an alternate wireless network based on network availability and the network selection information and may attempt origination of the call on the alternate wireless network. If a VoIP call is preferred over a circuit-switched voice call, then the terminal may first attempt origination of a VoIP call on a packet-switched wireless network. If the VoIP call fails, then the terminal may attempt origination of a circuit-switched voice call on a circuit-switched wireless network.

摘要： An access terminal includes a processing system configured to determine whether a voice over internet protocol (VoIP) communication channel is available. The processing system is also configured, upon entry into a VoIP-enabled communication environment, to provide without manual intervention a first request for one or more VoIP network connection resources to initiate communication between the access terminal and a packet data gateway over a VoIP communication channel. A method and a processing system are also provided for initiating a VoIP service.
