A system, method and device for adjusting a communication parameter for a network communicating with a communication device are provided. The method comprises: monitoring for a condition relating to a first network that has been in communication with the communication device; and determining whether an adjustment is to be implemented on a communication parameter of a second communication network that has been in communication with the communication device based on the condition and if so, implementing the adjustment to the communication parameter for the second communication network.

A system and method are described herein for standardizing an IT policy that is used to configure devices operating on a network. An IT policy can be generated that applies to a group of users or to one or more special users without having to define and store a new IT policy for each special user. This can be achieved by specifying global and per-user IT policy rules and merging these rules as needed to produce IT policy data.

Method of customizing a standardized IT policy

A system and method are provided for monitoring the quality of a communication session with a first electronic device. Should the communication session degrade, rather than dropping the communication session the user of a second electronic device communicating with the first electronic device is prompted to wait while an attempt is made to improve the quality of the communication session. Similarly if the user of the first electronic device moves out of a coverage area, rather than dropping the communication session the user of the second electronic device communicating with the first electronic device is prompted to wait until a new communication session can be established.

Soliciting first party in communication session to maintain call when degradation of connection to second party is anticipated

A method for signaling a transfer of a voice call communicated between a wireless device and a second device from a first access point to a second access point in a wireless network, the second device coupled to the first and second access points through a server, the method comprising: receiving at the server from the wireless device a message indicative of a pending transfer between the first and second access points, wherein the wireless device determines whether to send the message by monitoring a characteristic of signals received from each of the first and second access points; and, sending from the server to the second device a message indicative of the pending transfer to thereby prepare the second device for a possible interruption of the voice call.

Techniques for use in controlling an access point mode of operation of a mobile terminal are described. Initially, the mobile terminal operates in the access point mode of operation for communication with one or more other mobile terminals. While operating in the access point mode, the mobile terminal receives, from the one or more other mobile terminals, network information comprising one or more network identifiers which identify one or more wireless networks within coverage of the one or more other mobile terminals. The mobile terminal disables the access point mode of operation in response to identifying that at least one of the received network identifiers corresponds to a predetermined wireless network or predetermined type of wireless network. In one example, the mobile terminal is operative in accordance with IEEE 802.11, the received network identifiers comprise service set identifiers (SSIDs), and the predetermined wireless network is an enterprise network.

An Access Point (AP) advertises the availability of notifications, and this advertisement may be received and interpreted by stations (STAs), both by associated STAs and by non-associated STAs. Upon being informed of the availability of the notification message, a STA may be able to identify the notification message by analyzing the advertisement. If the contents of the notification message comprise a control message, the STA may act on the control message in a way that influences the STA's behavior. If the contents of the notification message indicate restrictions imposed by the AP, the STA may determine, in view of the restrictions, not to attempt association with the AP.

Incorporation of a notification in a network name

A mobile communication device invokes a first application or a second application. When the first application is invoked, the mobile device scans to search for one or more WLANs identified in a first subset of WLAN profiles. When the second application is invoked, the mobile device scans to search for one or more WLANs identified in a second subset of WLAN profiles. The first application may be a messaging application, such as a personal information manager (PIM) application, which may utilize WLANs having external network connectivity. The second application may be a streaming media application, which may utilize WLAN appliances having no external network connectivity. Alternatively, the second application may be a conference meeting application or military application which may utilize ad hoc networks having no external network connectivity.

Methods and apparatus for use in efficiently scanning for wireless networks based on application type

Techniques for efficient scanning for WLANs based on mobile device velocity are described. In one illustrative example, a mobile device identifies whether its velocity is less than or greater than a threshold value. While it is identified that the velocity of the mobile device is less than the threshold value, the mobile device scans to search for one or more WLANs identified in a first subset of WLAN profiles (e.g. 'stationary' WLANs). While it is identified that the velocity of the mobile device is greater than the threshold value, the mobile device scans to search for the one or more WLANs identified in a second subset of WLAN profiles (e.g. 'mobile' WLANs). Advantageously, a suitable WLAN may be more efficiently identified with use of a technique which reduces power consumption of the mobile device.

A system and method are described herein for standardizing an IT policy that is used to configure devices operating on a network. An IT policy can be generated that applies to a group of users or to one or more special users without having to define and store a new IT policy for each special user. This can be achieved by specifying global and per-user IT policy rules and merging these rules as needed to produce IT policy data. The IT policy can also be used to configure settings associated with storing electronic messages on the devices.

A method for conserving battery power in a wireless device coupled through an access point to a server in a network, the server being coupled to at least one client in the network, each of the wireless device, the at least one client, and the access point having a respective hardware address, the method comprising: receiving at the server through the access point a message indicative of the wireless device joining the network and providing the hardware address of the wireless device; updating a list of hardware addresses for clients in the network to include the hardware address of the wireless device, the list including a respective Internet Protocol ('IP') address for each hardware address; and, sending from the server to at least one of the wireless device, the at least one client, and the access point, the updated list of hardware addresses.

Example methods and apparatus to manage wireless device power consumption are disclosed. In accordance with a disclosed example method a data frame exchange is initiated with an access point of a wireless network. In response to not successfully completing the frame exchange with the access point, the access point is designated as providing the wireless terminal with fringe wireless signal coverage.
