Abstract: Methods, systems, and devices are described for reducing congestion in a wireless communications system. A second connection failure is detected, and a difference between a timestamp of the second connection failure and a timestamp of a first connection failure is calculated. Upon determining that the difference satisfies a first time threshold, information relating to one or more previous connection failures is cleared. A time period is identified. A number of connection failures from a cell that occur during the time period is identified. A determination is made as to whether the number of connection failures satisfies a threshold. Upon determining that the number of connection failures satisfies the threshold, a future connection request may be withheld for a time period.

Abstract: An access terminal pre-registers with a second access network via a first access network to ensure a quick handover in the future. Frequent pre-registration attempts are avoided by implementing a hysteresis timer that restricts when a pre-registration process can be initiated. The hysteresis timer is started when pre-registration is initiated by the access terminal. No new pre-registration attempts are permitted if the hysteresis timer has not expired. An abort condition can cause the hysteresis timer to be aborted early, and a new pre-registration can be initiated. Access points in the first access network may be grouped into one or more pre-registration zones. If the access terminal moves from a first access point to a second access point, a new pre-registration is skipped if the first and second access points have the same pre-registration zone or the second access point is aware of the pre-registration zone for the first access point.

Abstract translation: 接入终端经由第一接入网络与第二接入网络预先注册，以确保将来快速切换。 通过实施限制何时可以启动预注册过程的滞后定时器来避免频繁的预注册尝试。 当接入终端启动预注册时，启动滞后定时器。 如果迟滞定时器尚未到期，则不允许新的预注册尝试。 中断条件可能导致滞后定时器提前中止，并且可以启动新的预注册。 第一接入网络中的接入点可以被分组成一个或多个预注册区域。 如果接入终端从第一接入点移动到第二接入点，则如果第一和第二接入点具有相同的预注册区域或第二接入点知道预注册区域，则跳过新的预注册 为第一个接入点。

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., a network entity, may establish a connection between a user equipment (UE) and a packet data network, designate the packet data network with an always-on status, and notify the UE, while the UE is in the idle mode, when a loss of connection with the packet data network is detected. The UE may be connected to another packet data network when the loss of the connection occurs. A service provided by the packet data network may be designated as having an always-on status and the UE may be notified when a loss of the service is detected
