Embodiment Construction

[0049] The present invention will be described below by way of examples.

[0050] FIG. 3 is a block diagram illustrating a ranging opportunity allocation system 300 according to the present invention. As shown in FIG. 3 , the ranging opportunity allocation system 300 of the present invention includes: a message forwarding device 302, located on the side of the serving base station, for forwarding the first message received from the mobile station to the target base station, the first message including ranging validity indication; and ranging opportunity allocating means 304, located at the side of the target base station, for allocating ranging opportunities to the mobile station according to the ranging validity indication.

[0051] Wherein, the first message may be a handover confirmation message. The ranging validity indication is the first information, which indicates that the ranging parameters of the mobile station are valid. The ranging validity indication is the seco...

Abstract

The invention provides a distance-measuring distributing system and method, the system includes: message transmitting device which is on the service base station and used to transmit the first messages received by mobile station to the target base station, the first message contains efficient indication of distance-measuring; the distance-measuring distributing device, which is on target base station and used to distribute the distance-measuring chance according to efficient indication of distance-measuring. The method include: step S402, the service base station transmits the first message received by mobile station to target station, and the first message contains efficient indication of distance-measuring; and step S404, the target base station distributes the distance-measuring chance according to efficient indication of distance-measuring. The efficient indication of distance-measuring is taken by switching affirm messages, and the target base station can adopt different distance-measuring distributing method. When the mobile station has efficient distance-measuring parameter, the base station distributes the special-used distance-measuring chance, and can not conflict with other mobile stations, and reduce the bout number of measuring distance, and reduce the time delay of switch.

Description

technical field [0001] The invention relates to the communication field, in particular to a system and method for allocating range-finding opportunities. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX for short) is a broadband wireless access standard and a wireless metropolitan area network technology that can provide high-speed Internet-oriented connections. [0003] The wireless metropolitan area network technology can be divided into two parts: the air interface part (physical layer, MAC layer), and the end-to-end network architecture (IP and layers above IP). Among them, IEEE802.16 defines the air interface, and the WiMAX standard defines the end-to-end network architecture. [0004] 1. Air interface ranging [0005] Ranging is the process of ensuring the synchronization between the mobile station and the base station and parameter adjustment. Through the ranging process, the mobile station obtains time and frequency synchronizat...
