Description
Technical field
The present invention relates to WiMAX and insert the field, relate in particular to method, the Apparatus and system of reporting scanning result.
Background technology
WiMax system (Worldwide Interoperability for MicrowaveAccess, WIMAX), be called 802.16 wireless MANs again, this system can realize high coverage in data communication field, can cover 25～30 miles scope.
The WIMAX system is based on the serial wideband wireless standard in electronics and electrical engineers association (IEEE) 802.16 standards.Up to the present IEEE 802.16 standard series comprise IEEE802.16, IEEE802.16a, IEEE802.16c, IEEE802.16d, IEEE802.16e, IEEE802.16f and IEEE802.16g totally seven standards.Wherein, IEEE802.16, IEEE802.16a, IEEE802.16d belong to the fixed wireless access air-interface standard, and IEEE802.16e is that mobile broadband wireless inserts aerial standard.WIMAX adopts the air protocol of IEEE802.16e as it.
IEEE802.16e backward compatibility IEEE 802.16d, physical layer implementation and the IEEE 802.16d of IEEE 802.16e are basically identicals, main difference is to OFDM (OrthogonalFrequency Division Multiple Access, OFDMA) expand, to adapt to the needs of different carrier bandwidth.In order to support mobility, (MediaAcess Control MAC) has introduced a lot of new characteristics to IEEE 802.16e at media access control layer.The development trend of wireless access technology is by introducing new technology, as OFDM (Orthogonal Frequency Division Mltiplex, OFDM), multiple-input, multiple-output (Multiple Input Multiple Output, MIMO) etc., realize the more high power capacity of wireless broadband system, large coverage and have certain mobility more, wireless access technology coexists with 3G network and also complements one another.
WIMAX is on the basis of IEEE 802.16e, new enhancement techniques IEEE 802.16m has been proposed, the present requirement example of IEEE 802.16m is as follows: be supported on the above mobile object of speed per hour 350 kms and use, requiring descending largest data transfer speed is more than the 350Mbps, the up 200Mbps that then is not less than, bandwidth is 5MHz, 10MHz, 20MHz, 40MHz, and plan can utilize maximum 4 * 4 MIMO.When using the 20MHz bandwidth, (Time DivisionDuplex, when TDD) communicating, the partition data transmission speed requires downstream rate 40Mbps, more than the up 12Mbps to utilize the time to separate duplex operation.Require the access time and the switching delay of link layer to be respectively below the 10ms, below the 20ms in addition.In addition, IEEE 802.16m also will with existing IEEE 802.16e compatibility.Therefore, IEEE 802.16e technology is from becoming the focus of industry once appearance, and its International standardization process is carried out.
The WIMAX system by the base station (Basic Station, BS) and travelling carriage (Mobile Station, MS) two parts are formed, the electromagnetic wave that transmits and receives by radio receiving-transmitting unit wirelessly between BS and the MS communicates.Each BS uses a base station identity identification code (BasicStation Identity who is different from other BS, BS ID) identifies, BS ID is that a length is the field of 48 bits (Bit), for the difference of distinguishing BS ID is represented mode, the method that the BS ID that directly adopts 48Bits is identified BS is called base station identity sign (Full BS ID) in full, and Biao Shi BS ID is referred to as the BS id information by different way.Each BS has its coverage, BS can communicate with each BS in its coverage, BS and the MS of each BS timing in certain zone sends neighbor cell broadcasting (MOB_NBR_ADV) message and preserves described MOB_NBR_ADV message, and MS receives described MOB_NBR_ADV message and preserves described MOB_NBR_ADV message.The BS id information that comprises the BS in described certain zone in the described MOB_NBR_ADV message, described BSID information are arranged in described MOB_NBR_ADV message in order.At synchronization, a BS can communicate with a plurality of MS in its coverage, but MS can only keep communicating by letter at synchronization with a BS, and this BS is called the serving BS broadcasts of this MS.Along with moving of MS, MS may successively pass the coverage of a plurality of BS, and at this moment, the serving BS broadcasts of MS will change, MS will successively proceed communication to the BS that satisfies the communication quality requirement as the serving BS broadcasts of oneself, and this process is exactly usually said switching.For the continuity that guarantees to communicate by letter, reduce to switch the communication disruption that may bring, MS also will continue to detect the signal quality of each neighbor bss when keeping proper communication with current serving BS broadcasts, with the target BS of determining to switch, this process that continues to detect scans exactly.Like this, in case need to switch, MS just can switch to new communication quality BS preferably rapidly.Therefore scanning process is to guarantee to switch the committed step of carrying out smoothly.
