摘要:
One illustrative method for use by a host server in pushing messages to a mobile communication device involves the steps of causing a message to be sent to a relay network for delivery to the mobile communication device through one of a plurality of wireless communication networks which are communicatively coupled to the relay network; receiving, from the relay network, a result message when the mobile communication device is unavailable to receive the message through the wireless communication network, the result message comprising a message identifier which uniquely corresponds to the message; maintaining storage of the message in memory accessible by the host server after the result message is received; receiving, from the relay network, a status message which indicates that the mobile communication device is available to receive the message when the mobile communication device is available to receive the message through the wireless communication device; and causing the message to be sent again to the relay network for delivery to the mobile communication device in response to receiving the status message. During the unavailability of the mobile device, the relay network refrains from maintaining storage of the message in memory of the relay network.

A system and method for reducing congestion in wireless communication systems is provided. An unsolicited message reduction system includes a message detector and an all points bulletin (APB) generator. The message detector applies predefined filtering rules to identify and act upon unsolicited email messages to reduce the total number of transmissions in the wireless communication system. The filtering rules include global and user rules, with the global rules normally having precedence over user rules. The APB generator allows messages to be sent wireless mobile communication devices through direct wireless messages instead of through email messages.

A method (200) and an apparatus (300) in a wireless portable communication device (102) for maintaining appropriate authentication credentials required for a common data application in a current service network are provided. A method (400) in a wireless communication network (106) for providing current authentication credentials required for the common data application accessible through the wireless communication network (106) is also provided. The wireless portable communication device (102) has default authentication credentials required for the common data application in a default service network (106), receives (204) a data session configuration file including authentication credentials based upon a predetermined condition, prioritizes (206) between the default authentication credentials and the received authentication credentials, and uses (208) the authentication credentials having higher priority for the common data application in the current service network (110). The wireless communication network (106) maintains (404) the current authentication credentials indicative of currently required authentication credentials for the common data application, detects (406) a predetermined condition for transmitting the data session configuration file, and transmits (408) the data session configuration file having the current authentication credentials. Upon receiving (410), the wireless communication network (106) allows (412) proper access to the common data application upon receiving the current authentication credentials.

In one illustrative example, a method in a wireless router system for transmitting data packets to a mobile communication device through the wireless communication network based upon a round trip time associated with communication of each data packet is provided. The round trip time is a time period between the transmission of each data packet and reception of a corresponding acknowledgement signal from the mobile communication device. A number of data packets matched for a window size are transmitted to the mobile communication device, and a round trip time associated with communication of each of the transmitted data packets is measured. The window size for data packet transmission is re-sized by increasing the window size if the round trip time associated with the communication of each of the transmitted data packets is within a first time threshold, and decreasing the window size if the round trip time associated with the communication of any of the transmitted data packets is more than the first time threshold but less than a second time threshold. The window size is also decreased if the round trip time of any of the transmitted data packets is more than the second time threshold, where each such data packet is further marked as a lost data packet. A number of data packets matched for the re-sized window is subsequently transmitted, including a retransmission any data packets marked as lost. The steps of the method are repeated from the measuring step until data packets to be transmitted are exhausted.

摘要:
A wireless communication system, comprising a host service, a wireless router system coupled to the host service, a wireless network coupling the wireless router system and a wireless mobile communication device (“mobile device”), adaptively delivers data to the mobile device in the wireless communication system using a notification message delivery mechanism. Mobile device reports its session state to the wireless router at a regular interval or if there is a change in state. The host service sends out a message to the wireless router to query the state of the mobile device. If the state of the mobile device is determined to be in coverage (or logged on), the host service sends down the data message to the mobile device using a payload message (MTH) with certain parameters configured. The data is temporarily stored at the wireless router. If the device is available, the message is sent to the device over the wireless network. If the device is not available, the wireless router returns the payload message back to the host service, updating the status of the device. The wireless router also reports to the host service any change in device state. If the device is back in coverage, the payload message is then resent from the host service to the device.
