Problems solved by technology

However, this solution has the obvious disadvantage that when the mobile device is out of range of the WLAN access point, it will constantly search for new AP beacon signals
This search wastes power, a limited resource in mobile devices
[0019] Furthermore, the above proposal is only a partial solution to the general problem of wireless access discovery, since it only considers a subset of available access technologies

Embodiment Construction

[0044] Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings.

[0045] A wireless communication device and a method of access technology selection are disclosed. In the following description, numerous specific details are given in order to provide a thorough understanding of embodiments of the invention. It will be apparent, however, to one of ordinary skill in the art that these specific details need not be employed to practice the present invention.

[0046] In an embodiment of the present invention, a mobile communication device analyzes the effects of the environment on wireless propagation in its vicinity to determine whether the device is indoors or outdoors. By identifying possible environments, a subset of all access technologies that are most likely to occur in that environment can be selected and scanned, thus reducing the time and power used to scan for appropriate access technologies.

Abstract

A wireless communications device employs a method of access technology selection that comprises analysing radio signals for indications of the device's current physical environment. In response to this analysis, it is determined which of two or more candidate environments are the most likely current physical environment of the wireless communications device. The wireless communications device then selects, from among all possible access technologies, a subset of access technologies typical of the determined environment. The wireless communications device then performs a wireless access discovery over frequencies corresponding to said subset, and selects a suitable access technology thus found by the discovery process.

Description

technical field [0001] The present invention relates to an apparatus, method and processor control code for wireless communication. In particular, but not exclusively, the invention relates to establishing wireless communications among a number of possible radio access technologies. Background technique [0002] In recent years, the number of available wireless access technologies has proliferated, including eg Bluetooth, Wireless Local Area Network and 3G. Each access technology provides different types of connectivity to users, based on desired data rates, coverage area and mobility. [0003] Figure 1 illustrates the mobility characteristics for selecting commonly used access technologies according to data rate. It can be seen that each access technology provides different capabilities to the user, and it can be clearly seen that no one access technology is a suitable candidate to replace all other access technologies. [0004] Therefore, mobile communication devices se...
