Disclosed are an authorization management method and system for a signal transmission bandwidth of a DAS communication system. The system consists of an access unit, an extension unit, and a distal unit. The radio frequency access unit is connected to the extension unit. The extension unit is connected to the distal unit. The extension unit mainly implements the extension of a proximal unit port, the extension of a transmission distance, and a transmission bandwidth control function. The distal unit mainly implements the coverage of a radio frequency signal to a specific area. The signal transmission bandwidth of the extension unit is controlled by setting an authorization file formed by authorizing the transmission bandwidth on an extension unit device. When the signal transmission bandwidth configured by a user on the extension unit is not greater than the authorized bandwidth, the configuration becomes effective, and the system performs normal transmission. When the transmission bandwidth configured by the user on the extension unit is greater than the authorized bandwidth, the configuration is limited, the overflow bandwidth is not transmitted, and an abnormal indication is made. The present invention provides a flexible capacity allocation mode for a DAS, which indirectly expands the sales market.

A location update method, and a heterogeneous network communications system and a device are provided herein. The method includes: an information server receives a location update request message from a multimode terminal; the information server searches the pre-stored location area mapping information for the location area information of the second interface; and the information server sends the location update request message of the second interface to a second Paging Coordinator (PC) corresponding to the second interface, where the request message carries the found location area information of the second interface so that the second PC can update existing location area information of the second interface. The system includes an information server, a first PC and a second PC. Therefore, the interfaces of the multimode terminal do not need to initiate location update frequently, message interactions between the terminal and the network are reduced, and not all interfaces of the multimode terminal need to report location area information, thus saving power.

Location update method, heterogeneous network communications system and device

A method of paging for a wireless device with multiple radio interfaces corresponding to multiple access networks. The method provides a first interface from the multiple radio interfaces to listen to paging for the multiple radio interfaces; turns the rest of the multiple radio interfaces into deep-sleep mode; and maintains attachment for each of the deep-sleep interfaces to a corresponding serving base station or access point.
