Description
Technical field
The present invention relates to micro-wave access global inter communication (Worldwide Interoperability for MicrowaveAccess, WiMax) system, particularly relate to delivery method and the WiMax system of a kind of adjacent area message.
Background technology
Compare with now widely used various wireless network, WiMax technology has the advantage of oneself uniqueness.WiFi (Wireless Fidelity, WLAN (wireless local area network)) technology can provide the wireless access speed up to 54Mbps, but its transmission range is very limited, and effective radius is about 100 meters.3G (3rd Generation, third generation digital communication) mobile telephone system can provide boundless transmission range, but its access speed is but very slow.The appearance of WiMax just compensate for this two deficiencies.
As shown in Figure 1, the flow process of mobile station MS access WiMax network, specifically comprises the following steps:
101, MS catches down channel and obtains up channel parameter, and namely system descending is synchronous;
102, initial ranging (Ranging) process, MS passes through with base station BS mutual, and constantly inclined during adjustment and frequency deviation, carries out uplink synchronous accurate adjustment;
103, MS sends SBC-REQ message to BS to start SBC (SS Basic Capabilities, subscriber station basic capacity) consult, MS and BS consults PKM (Pair-wise Key Management, pairwise key manages) protocol version, certification policy;
104, BS sends the AGW (AccessGateway, IAD) that MS_PreAttachment_Req message is given tacit consent to it, notifies new MS and enters network;
105, the AGW receiving MS_PreAttachment_Req generates a new context block about this MS ID, and responds MS_PreAttachment_Rsp message to BS;
106, BS sends SBC-RSP message to the MS performing authentication architecture strategy;
107, BS sends MS_PreAttachment_Ack message to AGW, confirms that SBC-RSP is sent to MS;
108, EAP (Extensible Authentication Protocol, EAP) authorizing procedure, comprises EAP process and three step handshake information are mutual.Main purpose is that the legal identity of AGW to MS is tested, and the distribution of finishing equipment authentication and subscription authentication and encrypted material uses.Message subsequently all can carry out verifying (such as using CMAC (Cipher-based Message AuthenticationCode, the message authentication code based on ciphertext) to prevent message replay attack);
109, MS performs 802.16e registration process, sends REG-REQ message to BS, carries MS tenability in this message;
110, the result of EAP certification is transmitted to AGW by MS_Attachment_Req message by BS;
111, after AGW receives MS_Attachment_Req message, MS_Attachment_Rsp message is responded to BS;
112, BS sends REG-RSP message to MS, carries the suitable parameter response of AGW (tactful according to BS or) in message.When send the decision-making that REG-RSP depends on BS;
113, BS sends MS_Attachment_Ack message to AGW, and its MS_Attachment_Rsp message sent of notice AGW receives, and have sent REG-RSP message to MS and trigger the foundation that AGW initiates preset service stream;
114, Business Stream Establishing process (comprising link process of establishing Connections Establishment (DSA-REQ/RSP/Ack) and data link setup process Data Path Establishment (R6)), only has Business Stream to set up rear MS and could start to obtain IP address and transmitting user data.
Traditional mobile cellular network structure as shown in Figure 2, according to IEEE 802.16e agreement, MS is after access WiMax network, serving BS Serving BS needs the information of all adjacent areas around configuration, and the topology information of radio network can be carried out by MOB_NBR_ADV message according to the neighbor cell configuration information of system, for MS (Mobile Station, travelling carriage) provides the situation of contiguous BS and community.MS is in moving process, more and more weak with the signal quality of current Serving BS.In order to meet the service quality of user, inevitable requirement MS is switched to the better base station of signal quality.MS is according to the adjacent area message got, can by MOB_SCN-REQ message request system assignment one group scanning time slot, BS can with MOB_SCN_RSP message clearly to the information that the scanning gap that MS reply distributes is relevant to scanning with other, then MS can leave current Serving BS according to the content in this message, go to scan adjacent area BS, thus the signal quality of acquisition adjacent area BS is to determine the need of switching and to be switched on which BS.
According to the development trend of existing network, future market there will be so a kind of application scenarios, as shown in Figure 3.Personal user uses WiMax technology to realize Micro-cell (microcell) and covers in the home dwelling of oneself, and use WiMax macro cells (macrocell) to ensure wireless coverage in region widely, namely there is the situation comprising a large amount of families Micro-cell in a macro cells.MS to be limited in family Micro-cell and surrounding area thereof but can not to move to other Micro-cell, and there will be Handover in the frontier district of Micro-cell and macrocellular.
In above-mentioned application scenarios, if still according to original protocol configuration neighboring BS information and transmission neighboring broadcast messages, then owing to comprising multiple Micro-cell in a macro cells, will inevitably cause sending in the neighboring broadcast messages of travelling carriage and comprise a large amount of neighboring BS information.Although can carry out segmentation transmission to neighboring broadcast messages, this is all a huge challenge to the scan process ability of the bandwidth of air-interface of communication system and terminal.
