Embodiment
Specify the present invention with regard to the embodiment of the invention information shown in the accompanying drawing below.
Fig. 2 is the flow chart of the adjacent base station information method for reporting of mobile subscriber station.
See Fig. 2, just transmit information (S211) to the mobile subscriber station in the zone with the forms of broadcasting about adjacent base station in serving base station.
Mobile subscriber station carries out the scanning of adjacent base station with (S211 S212), obtains neighbor base station signal intensity and frame information (S213) then synchronously.Exist from (S214) in the situation in the adjacent base station information request of serving base station just, mobile subscriber station is to just in the information (S215) of serving base station transmission adjacent base station.
In order to be connected the base station that its position has the peak signal size, mobile subscriber station is according to the signal strength signal intensity of just measuring adjacent base station in the instruction of serving base station.Therefore, when measuring the adjacent base station signal, find to satisfy and equate with predetermined reference or during than the base station of its big signal magnitude, mobile subscriber station is to the information that measurement just is provided in serving base station.
Fig. 3 is the flow chart according to the adjacent base station information method for reporting of the mobile subscriber station of an embodiment.
See Fig. 3, just transmit information to the mobile subscriber station in the zone with the forms of broadcasting about adjacent base station in serving base station.
Mobile subscriber station carries out the scanning of adjacent base station, and (S312 S313), obtains the signal strength signal intensity (CINR: carrier wave and interface noise ratio) and the frame information (S314) of adjacent base station then with synchronously.The mobile subscriber station storage is measured the adjacent base station information that obtains through this.Then, no matter from just in the request of serving base station, mobile subscriber station is to just in serving base station report measurement result.Particularly, to just in the situation of serving base station transmission handoff request message (S315), mobile subscriber station can be before the transmission handoff request message with afterwards to just at serving base station transmission this measurement report (S316).
The example that adjacent base station information gives information shown in the table 1.

Fig. 4 is the flow chart according to the adjacent base station information method for reporting of the mobile subscriber station of another embodiment.
See Fig. 4, in case open the power supply of mobile subscriber station, mobile subscriber station is from just receiving the information (S412) in the cycle that starts scanning neighbor base stations at serving base station receiving neighbor bs information (S411) with from adjacent base station.
The mobile subscriber station tunes to adjacent base station (target BS) synchronously, and picked up signal intensity and frame information (S414).Be necessary in the situation of handover that based on measured signal strengths decision the mobile subscriber station request is from just at serving base station handover (S415).
Before or after handover, mobile subscriber station is to just in the serving base station transmission information (S416) from the adjacent base station of tuning synchronization gain to adjacent base station.Can pass through MAC (medium access control) administrative messag and transmit adjacent base station information.
Just in the request of serving base station, the service quality that continues service (below abbreviation QoS) parameter (S417) is provided to the adjacent base station transmission according to mobile subscriber station.Whether the adjacent base station notice just can provide QoS (S418) in serving base station.
Just at serving BS according to the response that receives from adjacent base station, recommend to carry out to mobile subscriber station handover handover target BS (target BS) (S419).The mobile subscriber station request that receives the handoff target base station recommendation information is from just discharging service (S420) at serving BS.Handoff target base station provides uplink message (S421) and carries out the network re-registration process to the mobile subscriber station that has carried out handover.
At BWA, the base station of inserting is through the information of broadcast to the notice of the mobile subscriber station in sub-district adjacent base station.Do like this, the message that the mobile subscriber station of having measured the signal strength signal intensity of adjacent benchmark can pass through to ask handover is to just transmitting adjacent base station information in serving base station.
Fig. 5 is the flow chart according to the neighbor base station signal intensity transmission method of prior art.
See Fig. 5, just transmit in order to transmit the cyclical information of neighbor base station signal intensity (S511) to mobile subscriber station in serving base station.
The scanning that mobile subscriber station carries out adjacent base station with synchronously (S112, S113).The mobile subscriber stands in the signal strength signal intensity (S114) of measuring adjacent base station in scanning and the Synchronous Processing.Mobile subscriber station uses handoff request message then, through circulation from just coming in serving base station transmission, to just the signal strength information of serving base station transmission adjacent base station (S115, S116).
According to the method for above-mentioned explanation, to the signal strength measurement at serving base station periodic transfer adjacent base station just the time, mobile subscriber station uses handoff request message transmission measurement information.Therefore, when the signal strength signal intensity of cycle report adjacent base station, use handoff request message, and its hand-off request made from mobile subscriber station is difficult to differentiation.So the base station need keep the response to handoff request message.
Fig. 6 is the flow chart of neighbor base station signal intensity transmission method according to an embodiment of the invention.
See Fig. 6, just transmit cyclical information (S611) to mobile subscriber station, with the signal strength signal intensity of transmission adjacent base station in serving base station.The scanning that mobile subscriber station carries out adjacent base station with synchronously (S612, S613).The mobile subscriber stands in the signal strength signal intensity (S614) of measuring each adjacent base station in scanning and the Synchronous Processing.Mobile subscriber station then operation report message through from just in the circulation of serving base station transmission, to just the signal strength information of serving base station transmission adjacent base station (S615, S616).
This report message be periodically to just at medium access control (MAC) administrative messag of serving base station transmission neighbor base station signal intensity, and its specific messages with the signal message of transmission adjacent base station is corresponding.
The example of specific messages in the signal strength signal intensity of the adjacent base station of transmission shown in the table 2.
