Abstract: In accordance with the teachings described herein, systems and methods are provided for always-on wireless IP communication. An access provider network (APN) that includes an always-on packet data serving node (PDSN) may be used to communicate over a wireless communication link with a mobile station. The PDSN may include an inactivity timer and may be used to set the inactivity timer to an inactivity timer starting value and send a starting value estimate to the mobile station over the wireless communication link, wherein the starting value estimate is a function of the inactivity timer starting value. The mobile station may include an inactivity timer estimate and may be used to receive the starting value estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN.

Abstract: A system and method of polling for a network identifier value is provided. Within a wireless device, a transport layer or application layer polls a radio layer for a network identifier value on a first basis. However, upon occurrence of an event of a predefined type, the transport layer polls for the network identifier value on a more frequent basis than the first basis. At some later time, the transport layer polls for the network identifier value on the first basis. Accordingly, the transport layer achieves a balance of polling frequently at certain times so as to obtain an accurate network identifier value while minimizing undue polling at other times so as to conserve battery power.

Abstract: A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.

Abstract: In one embodiment, a scheme is disclosed for managing network traffic load upon outage of a network node disposed in a wireless packet data network, wherein the network node is adapted to serve a substantially large number of mobile nodes using respective data connections. Upon encountering an outage-causing condition, the network node releases the data connections and determines to suppress generation of session termination messages that would have otherwise been generated for transmission to the mobile nodes.

Abstract: In one embodiment, a scheme is disclosed for managing network traffic load upon outage of a network node disposed in a wireless packet data network, wherein the network node is adapted to serve a substantially large number of mobile nodes using respective data connections. Upon encountering an outage-causing condition, the network node releases the data connections and generates session termination messages for transmission to the mobile nodes. Responsive to receiving the session termination messages, the mobile nodes variably delay their data session reconnect requests based on randomization.

Abstract: Method, and associated apparatus, for operating a hybrid access terminal operable in a CDMA 1x/EVDO hybrid communication session system. The hybrid access terminal is operable to communicate pursuant to an EVDO communication session and to a PPP communication session. The opening and closing of the communication sessions are independent of one another. Opening of one session does not require opening of another of the sessions. And, closing of one of the sessions does not require closing of the other of the sessions.

Abstract: Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

Abstract: Apparatus, and an associated method, for facilitating routing of data in a packet radio communication system. A clone list is downloaded to the mobile node and stored at a clone list depository thereat. The clone list includes a plurality of entries, each of which provides routing information needed to route data when the mobile node is positioned within coverage areas encompassed by differing networks. A determination is made whether the clone list includes appropriate routing information to route a data packet sent by the mobile node positioned in a particular area encompassed by a particular network portion. If the clone list includes an entry containing such information, the need separately to request such information is obviated.

Abstract: Methods and apparatus for controlling wireless network operations associated with a flow control process which terminates data communications to a mobile station based on an out-of-coverage condition between the mobile station and a wireless communication network. In the wireless communication network, an indication is identified which indicates whether a mobile station utilizes an always-on connection for a data service. Based on the indication indicating that the mobile station utilizes the always-on connection, the flow control process is bypassed. Otherwise, the flow control process is performed. The always-on connection may be utilized for an e-mail application for the mobile station and involve a Point-to-Point Protocol (PPP) session.
