A wireless router employing a technique to couple a plurality of host services or host systems and a plurality of wireless networks. A method to route data items between a plurality of mobile devices and a plurality of host systems through a common wireless router. A point-to-point communication connection is preferably established between a first host system and a common wireless router, a mobile network message at a mobile device is generated, the mobile network is transmitted via a wireless network to the common wireless router which in turn routes a data item component of the mobile network message to the appropriate host service.

Wireless router system and method

A router receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes an indication field which includes a return packet indication on whether to send a return packet to the host, an identifier field which includes an identifier which identifies the device, and a payload field which includes a payload of the message. When the indication is set to a first, setting and the message is not being delivered to the device, the router sends to the host a return packet which indicates that the message is not being delivered to the device. When the indication is set to a second setting and the message is not being delivered to the device, the router does not send to the host the return packet which indicates that the message is not being delivered to the device.

Apparatus, and an associated method, for providing routing information to a mobile node operable in a radio communication system. The routing information is used by the mobile node to address data messages that are to be communicated to a relay host, or other, device. The routing information that is provided to the mobile node includes a plurality of separate routing sequences. Different ones of the routing sequences are used by the mobile node, depending upon at what location that the mobile node is positioned when the data message is sent. A registration server is used by which to create the routing information, responsive to indications of a home network associated with the mobile node and a current location of the mobile node.

In a network having a plurality of subscriber devices, a plurality of base stations and a server, a system and method of modifying policy settings are provided. Each base station transmits wirelessly across a geographic region. A subscriber device, capable of roaming between regions, establishes a wireless link with the server via the base stations. The network contains a communication policy determining from which other communication devices a subscriber device can receive voice calls. The server updates the policy based on requests from subscriber devices. The determination of whether to update the policy can be based on a record of rejections respective to the caller requested to be blocked. Alternatively, the policy can be updated according to a trust policy maintained on the server respective to the subscriber device making the request; the trust policy represents the procedure to follow when a request is received from that subscriber device.

A wireless router employing a technique to couple a plurality a host services or host systems and a plurality of wireless networks. A method to route data items between a plurality of mobile devices and a plurality of host systems through a common wireless router. A point-to-point communication connection is preferably established between a first host system and a common wireless router, a mobile network message at a mobile device is generated, the mobile network message is transmitted via a wireless network to the common wireless router which in turn routes a data item component of the mobile network message to the appropriate host service.

A messaging server forwards emails to mobile communication devices of users to whom the emails were respectively addressed. An antivirus server determines whether an email addressed to a user of a mobile communication device, to be forwarded by the messaging server to the mobile communication device, is infected with a virus. In response to determining the email is infected with a virus, a bulletin generator transmits, to the mobile communication devices besides the mobile communication device of the addressee of the email determined to be infected, an all points bulletin message disclosing the existence of the virus. The bulletin message is transmitted directly to, instead of via email to, the wireless mobile communication devices.

Wireless communication system congestion reduction system and method

Distributed assembly of data packets into messages at a group of interface devices that receive data packets from within a coverage area. Each interface device in the group will take ownership of a sequence of data packets forming a message when a data packet of the message meeting predetermined criteria is received by that interface device. Once an interface device takes ownership of a sequence of data packets, it sends a request to the other interface devices for any missing data packets of the sequence that the ownership claiming interface does not have, and then assembles message upon receiving all the data packets of the sequence.

Distributed wireless packet assembly

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.

Techniques in a wireless device for use in accessing a common data application with a service network which is external to a plurality of wireless networks are described. The device receives a data session configuration file which includes a list of the plurality of wireless networks mapped against authentication credentials associated with each wireless network. The device communicates with a current one the wireless networks. The device selects from the list one of the authentication credentials that is associated with the current wireless network. The device submits, via the current wireless network, the selected authentication credentials for establishing a packet data session via the current wireless network. The device then accesses, via the current wireless network using the packet data session, the common data application with the service network which is external to the current wireless network.

A system and method for redirecting data from a host system (or messaging server) to one or more mobile data communication devices via a wireless packet data network is provided in which the wireless packet data network dynamically assigns addresses to the one or more mobile data communication devices on an as-needed basis. A redirector application operating at the host system is configured by each user to continuously redirect certain data to the wireless packet data network, as the data is received (or otherwise altered) at the host system. Two methods are provided for communicating the redirected data from the network to the mobile device. In a first method, the mobile device is configured to periodically contact a store-and-forward server within the wireless network, which, when contacted, assigns a network address to the mobile device and then transmits the stored, redirected data to the mobile device. In a second method, the network transmits a connection request command to the mobile device via a parallel voice network, or via a command channel, or other type of low-bandwidth data channel. The mobile device then contacts the data network and requests a network address so that the store-and-forward server can send the redirected data to the mobile device.

The present invention provides a system and method of modifying policy settings in a network having a plurality of subscriber devices. An embodiment includes a plurality of base stations, each capable of wirelessly transmitting across a geographic region and a server. A cell-phone, capable of roaming between regions, is operable to establish a wireless link with the base stations and through the base stations, with the server. The network contains a communication policy determining from which other communication devices a subscriber device can receive voice calls. The communication policy is updated, by the server, based on requests from the subscriber devices. Once a request is received from a subscriber device, the determination whether to update the communication policy can be based on a record of rejections respective to the caller requested to be blocked. Alternatively, the communication policy can be updated according to a trust policy maintained on the server respective to the subscriber device making the request; the trust policy represents the procedure to follow when a request is received from that subscriber device.
