The management device, the management system and management method of the radio local area network service for the multiple mode portable communication device

摘要

Radio access point manages the radio service for the multiple mode radio communication device radio wide area network (WWAN) on the basis of the signal. Access point transmits device approach message to WWAN on the basis of the approach characteristic to access point of the multiple mode radio communication device. Here, approach characteristic is based on the WWAN signal at least partly. Device approach message the network which service presently is offered to the multiple mode radio communication device may show the execution demand for the alternative network acquisition procedure which establishes the radio service from the alternative network which differs. Present network with WWAN, the WWAN signal is transmitted from the communication device and when they are the WWAN rising corpen signals which are received with access point, access point, the approach characteristic for the access point of the communication device, at least partly specifies on the basis of the WWAN rising corpen signals. As for access point, for example, it judges whether or not it should offer WLAN service to the multiple mode radio communication device in feature of the WWAN signal such as power level and quality of the signal on the basis at least of partly. Alternative network acquisition procedure from WWAN confronts the multiple mode radio communication device, alternative network is made to search, access point is made to search, among the indications which alternative network is acquired at least it is possible to include one.
