Description

TECHNICAL FIELD The present invention relates to wireless communication technologies, and more particularly to a mobile station (MS, Mobile Station) access method, a wireless communication system, a mobile relay station, and a base station.

BACKGROUND OF THE INVENTION In order to meet the growing demand for broadband wireless communications, ever-increasing carrier frequencies are being used in new protocols and systems.

Book

However, the attenuation of radio waves increases with increasing frequency. Therefore, high carrier frequencies are bound to face high attenuation, which further limits the coverage of base stations. In order to solve the coverage problem of the base station, it is usually necessary to use a relay station (RS, Relay Station) to enhance the wireless communication signal between the base station (BS, Base Station) and the mobile station (MS). There is no need for wired transmission between RS and BS, and communication only through wireless links, so it has the advantages of low cost and simple deployment.

In IEEE 802.16j, one scenario of RS is the case of a mobile relay station (MRS). For example, deploy MRS in a train to serve the MS inside the train. In this case, the MRS moves with a large number of MSs and assists them in moving.

A group node can be defined as a plurality of nodes with the same movement rule, and the movement of the group node can be referred to as group movement, and multiple nodes in the group node exhibit similar movement paths and movement timings, which are almost simultaneously from a network entity. Coverage enters another network entity coverage. The group mobility problem in IEEE802.16j refers specifically to the case where the MRS and its subordinate MS move simultaneously.

In the prior art, a detailed implementation process is provided for the MS network access process in the case where the RS is a fixed RS (fixed RS) or a nomadic RS (nomadic RS), including: MS and MRS are physically synchronized; MS and MRS are time-shifted, The frequency offset adjustment; the MS performs an initial ranging request to the MRS; the MRS forwards the ranging message to the BS by using its own Basic CID (Connection Identifier); if the BS receives the Basic CID of the RS as the header CID and includes the MS The media access control (MAC, Media Access Control) address ranging request (RNG-REQ) message, the BS allocates Basic and Primary CIDs to the MS, and responds through the Basic CID of the RS, and the response message includes the MS allocation. The management CIDs and the MS MAC address; after receiving the response message, the RS transfers the initial ranging CID to the MS, and the MS obtains the management CIDs allocated by the BS. The subsequent network access process is the same as the process in the 802.16e standard, but the information between the MS and the BS. The interaction is forwarded by the RS and will not be described here.

In the above prior art process, the scenario of RS movement is not considered, and the case where a large number of MSs move with RS is not considered. In the group mobility scenario, according to the connection identifier (CIDs) management method in the existing MS network access process, when the RS performs handover, all the MSs under it also need to be switched, and all MSs switch at almost the same time, the access link and The CIDs of the trunk link must be replaced. This will increase the signaling overhead. The air interface access synchronization process causes a large number of conflicts, which has a huge impact on the processing of network devices and may even cause network congestion.

BEST MODE FOR CARRYING OUT THE INVENTION In order to make the objects, technical solutions and advantageous effects of the present invention more comprehensible, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

A mobile station MS network access method provided by an embodiment of the present invention includes:

The BS receives the first management CIDs, allocates the second management CIDs to the MS, and sends the second management CIDs to the MRS, according to the A management CIDs for group information update;

The MRS forwards the interaction information between the MS and the BS in the subsequent network access process according to the mapping relationship.

FIG. 1 is a flowchart of Embodiment 1 of an MS network in accordance with the present invention. In this embodiment, the MRS establishes a mapping relationship between itself and the two sets of CIDs allocated by the BS to the MS, and the MS initiates a service connection establishment, and the BS separately enjoys the key. The MRS allocates CIDs to the MS, and the BS also allocates CIDs to the MS. However, the CIDs allocated by the BS to the MS are unknown to the MS, and the mapping relationship between the two sets of CIDs is maintained on the MRS. When the MS-related network needs to send related management messages to the BS via the MRS, the CID is replaced in the message header. The BS can update the group information (MS-Info, MRS-Info) according to the network access condition of the MS, and the MRS also updates the mapping relationship between the two sets of CIDs. The group information may include: address information of the MS, CIDs information, and identifier information of the MRS. The process includes:

In step 101, the MS performs physical synchronization with the MRS.

Step 102: The MS and the MRS perform time offset and frequency offset adjustment.

Step 103: The MS performs an initial Ranging request to the MRS, and requests the MRS to allocate management CIDs, including: Basic CIDs and Primary CIDs.

Step 104: The MRS sends the management CIDs allocated to the MS to the BS through the Basic CID of the MRS in the RNG-REQ message, and may also send the message to the BS through other messages, and request the BS to allocate management CIDs to the MS.

Step 105: The BS receives the Basic CID whose message header CID is the MRS, and includes the MS MAC address and the RNG-REQ message of the management CIDs allocated by the MRS to the MS, then the BS responds to the request, and the management CIDs allocated by the BS to the MS are The ranging response message (RNG-RSP) is sent to the MRS; the management CIDs information allocated by the MRS for the MS is saved, and the group information maintenance update is performed.

Step 106: After receiving the ranging response message sent by the BS, the MRS saves the management CIDs allocated by the BS to the MS, and the management CIDs allocated to the MS by the MRS are returned to the MS through the RNG-RSP message, and the MRS establishes the two sets of management CIDs. The mapping relationship between them. After receiving the RNG-RSP containing the management CIDs allocated by the MRS for the MS, the MS performs the subsequent network access process.

Step 107: The MS performs capability negotiation with the BS. After receiving the capability negotiation request message sent by the MS, the MRS replaces the Basic CID allocated by the MS in the message header with the Basic CID allocated by the MS for the MS according to the mapping relationship between the two sets of management CIDs, and forwards the basic CID to the BS; The capability negotiation request message sends a capability negotiation response message to the MRS;

After receiving the capability negotiation response message sent by the BS, the MRS replaces the basic CID allocated by the MS in the message header with the Basic CID allocated by the MRS for the MS according to the mapping relationship between the two management CIDs, and forwards the packet to the MS for processing.

Step 108: The MS and the BS perform authentication authentication. The replacement of the CID in the corresponding header is consistent with step 107. In step 109, the MS registers with the BS. The replacement of the CID in the corresponding header is consistent with step 107.

Step 110: The MS establishes a service connection with the BS, and the establishment process is as shown in FIG. 2 .

Since security is established between the BS and the MS, the MRS cannot change the content of the message body of the Dynamic Service Addition (DSA).

Step 201: After receiving the service connection establishment request message sent by the MS, the MRS allocates service CIDs to the MS, and performs message header CID replacement according to the mapping relationship between the two sets of management CIDs, and after the replaced service connection establishment request message The service CIDs allocated by the additional MRS for the MS are handed over to the BS.

Step 202: After receiving the service connection establishment request message from the MRS, the BS allocates service CIDs to the MS, and places the service CIDs allocated by the MRS for the MS into the message payload of the service connection establishment response message, and the response message The service CIDs allocated by the BS to the MS are then appended to the MRS.

In this step, after receiving the service connection establishment request message, the BS may return a reception response message to the MRS, and the MRS receives the reception response message and sends the response message to the MS.

Step 203: After receiving the service connection setup response message from the BS, the MRS obtains the service CIDs allocated by the BS attached to the MS, and replaces the message header CID with the MRS according to the mapping relationship between the two sets of management CIDs. The management CIDs allocated by the MS forwards the received service connection establishment response message to the MS, and establishes a mapping relationship between the two sets of service CIDs.

After receiving the service connection setup response message sent by the MRS, the MS may further send an acknowledgement message to the MRS, and the MRS forwards the received acknowledgement message to the BS.

At this point, the MS completes the network access process under MRS. If the MS fails to access the network, the BS updates the group information again, and the MRS also updates the mapping relationship between the two sets of CIDs.

The second embodiment of the MS network access method of the present invention: the MRS establishes a mapping relationship between the two sets of CIDs allocated by the MS and the MS, and the MS initiates a service connection establishment, and the MRS shares a key with the BS. The MRS allocates CIDs to the MS, and the BS also allocates CIDs to the MS. However, the CIDs allocated by the BS to the MS are unknown to the MS, and the mapping relationship between the two sets of CIDs is maintained on the MRS. During the MS network access process, the relevant management message needs to be sent to the BS via the MRS, and the CID is replaced in the message header. The BS can update the group information according to the network access situation of the MS, and the MRS also updates the mapping relationship between the two sets of CIDs.

In the embodiment, the network access process of the MS is different from the embodiment shown in FIG. 1 in the process of establishing a service connection. As shown in FIG. 3, the process includes:

Step 301: The MS establishes a service connection with the BS. After the MRS and the BS share the key, the MRS receives the service connection establishment request message sent by the MS, and allocates the service CIDs to the MS, and replaces the CID in the message header and forwards the message to the BS.

Step 302: After receiving the service connection establishment request message sent by the MRS, the BS allocates service CIDs to the MS. The message body of the connection setup response message includes the service CIDs allocated by the BS for the MS, and the primary CID assigned by the BS for the MS is sent to the MRS for the CID of the message header.

Step 303: After receiving the service connection setup response message from the BS, the MRS obtains and saves the service CIDs allocated by the BS carried in the message for the MS; reconstructs the service connection establishment response message, and fills the MRS of the message body in the response message The service CIDs allocated by the MS are sent to the MS as the CID of the message header, and the MRS establishes the mapping relationship between the two sets of service CIDs.

The third embodiment of the present invention is as follows: The MRS establishes a mapping relationship between the two sets of CIDSs allocated by the MS and the MS, and the BS initiates a service connection establishment, and the BS separately enjoys the key. The MRS and the BS respectively allocate CIDs to the MS, but the CIDs allocated by the BS to the MS are unknown to the MS, and the mapping relationship between the two sets of CIDs is maintained on the MRS. When the MS-related network needs to send related management messages to the BS via the MRS, the message header CID is replaced. The BS can update the group information according to the network access situation of the MS, and the MRS also updates the mapping relationship between the two sets of CIDS.

The difference between the MS network access flowchart and the flow shown in Figure 1 is reflected in the process of establishing a BS-initiated service connection. As shown in Figure 4, the service connection establishment process includes:

The BS establishes a service connection with the MS. Due to the BS's exclusive key, MRS cannot change the contents of the DSA related message body. Step 401: The BS brings the service CIDs allocated for the MS to the MRS through the BS-initiated service connection establishment request message. Step 402: After receiving the service connection establishment request message from the BS, the MRS obtains and saves the service CIDs allocated by the BS for the MS, allocates the service CIDs to the MS, and carries the service CIDs allocated by the MRS to the MS in the service connection establishment. The response message is returned to the BS.

Step 403: After receiving the service connection setup response message from the MRS, the BS obtains the service CIDs allocated by the MRS for the MS, constructs a new service connection establishment request message, fills the message body with the service CIDs allocated by the MRS for the MS, and passes the BS. The Primary CID assigned to the MS is sent to the MRS for the CID of the message header.

Step 404: After receiving the new service connection establishment request message from the BS, the MRS allocates the Primary to the MS by using the MRS. The CID in the CID replacement header is forwarded to the MS. The MRS establishes a mapping relationship between the two sets of service CIDs.

The fourth embodiment of the present invention is as follows: The MRS establishes a mapping relationship between the two sets of CIDSs allocated by the MS and the MS, and the BS initiates a service connection establishment, and the RS shares a key with the BS. The MRS and the BS respectively allocate CIDs to the MS, but the CIDs allocated by the BS to the MS are unknown to the MS, and the mapping relationship between the two sets of CIDs is maintained on the MRS. When the MS-related network needs to send related management messages to the BS via the MRS, the message header CID is replaced. The BS can update the group information according to the network access situation of the MS, and the MRS also updates the mapping relationship between the two sets of CIDS.

The difference between the MS network access flowchart and the flow shown in FIG. 1 is reflected in the process of establishing a BS-initiated service connection. As shown in FIG. 5, the service connection establishment process includes:

Step 501: The BS sends the service CIDs allocated for the MS to the MRS by using a service connection establishment request message initiated by the BS. Step 502: After receiving the service connection establishment request message from the BS, the MRS acquires and saves the service CIDs allocated by the BS for the MS, allocates service CIDs to the MS, establishes a mapping relationship between the two sets of service CIDs, and constructs a new service connection. A request message is established, and the service CIDs allocated by the MRS for the MS are filled in the message body, and the Primary CID allocated by the MRS for the MS is forwarded to the MS as the CID in the message header.

Step 503: After receiving the service connection establishment request message from the MRS, the MS returns a reception response message to the MRS. After receiving the reception response message sent by the MS, the MRS replaces the CID in the message header and forwards the message to the BS. This step is an optional step.

At this point, the MS completes the network access process under MRS. If the MS fails to access the network, the BS updates the group information again.

MRS also updates the mapping between the two sets of CIDS.

The first MS network access method provided by the embodiment of the present invention allocates CIDs to the MS through the MRS and the BS respectively, and the MRS maintains the mapping relationship between the two sets of CIDs, so that the CID information of the access link is not in the group mobile switching process. The change occurs, and only the target BS allocates the corresponding relay link CID to all the MSs in the MRS, and the MRS performs the corresponding CID mapping relationship update, thereby reducing the air interface signaling overhead of a large number of MS simultaneous handovers, and reducing the network. burden.

After the MS accesses the network by using the first method, the MS reconnects after accessing the network and the interaction information with the BS during the handover process, and the MRS still performs the message header according to the mapping relationship between the two sets of management CIDs that have been established. After the CID is replaced, the MRS replaces the message header with the corresponding management CID allocated by the MRS to the MS when forwarding the information sent by the BS to the MS. When forwarding the information sent by the MS to the BS, the message header is replaced by the BS as the MS. The corresponding management CID assigned.

The method for the second MS to access the network provided by the embodiment of the present invention includes: The mobile relay station MRS receives the initial ranging request from the MS, allocates a management connection identifier CIDs to the MS, and sends it to the BS through the management connection tunnel;

The BS receives the management CIDs, and updates the group information according to the management CIDs;

MRS will send management CIDs to MS;

The MRS and the BS exchange information in the subsequent network access process through the management connection tunnel.

The fifth embodiment of the MS network access method of the present invention: the MRS and the BS are connected through a tunnel, and the MS initiates a service connection establishment process, and the BS exclusively enjoys the security key. MRS assigns CIDs to the MS. During the MS network access process, the BS allocates related tunnels to the MRS and maintains the group relationship. The tunnel is divided into a management connection tunnel and a service connection tunnel. During the process of the MS accessing the network, the MRS and the BS need to communicate with each other through the corresponding management connection tunnel. If the MS fails to access the network, the BS updates the group relationship again.

FIG. 6 is a flowchart of Embodiment 5 of a method for accessing a network according to the present invention, where the process includes:

Step 601: The MS performs physical synchronization with the MRS.

Step 602: The MS and the MRS perform time offset and frequency offset adjustment.

Step 603: The MS sends an initial ranging request to the MRS, requesting the MRS to allocate management CIDs thereto.

Step 604: After receiving the initial ranging request from the MS, the MRS allocates management CIDs to the MS, carries the CIDs in the ranging request message, and sends the information to the BS through the management connection tunnel between the BS and the MRS.

Step 605: The BS receives the ranging request message from the MRS, and sends a ranging response message to the MRS in the corresponding management connection tunnel, and updates the group information saved by the received information according to the information carried in the received ranging request message.

Step 606: After receiving the ranging response message from the BS, the MRS carries the management CIDs allocated by the MRS to the MS in the ranging response message, and sends the message to the MS.

Step 607: The MS sends a capability negotiation request message to the MRS, where the CID of the message header is the Basic CID allocated by the MRS to the MS. After receiving the capability negotiation request message sent by the MS, the MRS is encapsulated in the corresponding management connection tunnel and sent to the BS. After receiving the capability negotiation request message from the MRS, the CID assembly response message is encapsulated in the corresponding management connection tunnel and sent to the MRS. After receiving the response message, the MRS decapsulates and forwards the packet to the MS.

Step 608: The MS and the BS perform authentication authentication. The message forwarding process is the same as step 607.

In step 609, the MS registers with the BS. The message forwarding process is the same as step 607.

Step 610: The MS establishes a service connection with the BS. The establishment process is shown in Figure 7:

Step 701: After receiving the service connection establishment request message sent by the MS, the MRS allocates the service CIDs to the MS, and adds the service CIDs allocated by the MRS to the MS after the request message, and the encapsulation is sent to the BS in the corresponding management connection tunnel.

Step 702: After receiving the service connection establishment request message from the MRS, the BS decapsulates and responds, and sets the MRS as The service CIDs allocated by the MS are placed in the message body of the service connection establishment response message, and the service connection establishment response message is constructed by using the same CID as the received request message header, and the constructed service connection establishment response message is encapsulated in the corresponding management connection. Sent to the MRS in the tunnel.

Step 703: After receiving the service connection setup response message from the BS, the MRS decapsulates and forwards the packet to the MS.

Manage CIDs as message headers for information interaction.

A third MS network access method provided by the embodiment of the present invention includes:

After the MS and the MRS perform parameter adjustment and initial ranging, the MS sends a basic capability negotiation request to the MRS.

Information for group information maintenance;

The subsequent network access process of the MS and the MRS includes: authentication authentication, registration, and service connection establishment process, in subsequent In the network access process, the MRS exchanges information with the ASN-GW through the BS.

The seventh embodiment of the present invention is that the MRS is powerful enough to implement all the functions of the existing BS. In the case of MRS, the BS function is weakened and is only used to maintain group information and complete information transmission between MRS and ASN-GW. In this case, the network access process of the MS is as shown in Figure 9, which includes the following steps:

In step 901, the MS performs physical synchronization with the MRS.

Step 902: The MS and the MRS perform parameter adjustment and initial ranging.

Step 903: The MS initiates a basic capability negotiation request to the MRS.

Step 904: The MRS receives the basic capability negotiation request of the MS, and sends a NetEntry MS State Change Request message to the ASN-GW to notify the ASN-GW that a new MS wants to enter the network, and the message needs to be transited through the BS. The BS can obtain related information in the message for group information maintenance.

Step 905: After receiving the state transition request message from the MRS forwarded by the BS, the ASN-GW returns a state transition response message (NetEntry MS State Change Response), and the message is forwarded to the MRS through the BS.

Step 906: After receiving the status transition response message, the MRS sends a capability negotiation response message to the MS.

Step 907: The MRS sends a status transition confirmation message to the ASN-GW to confirm that the capability negotiation response message has been sent to the MS. This step is an optional step.

Step 908: The MS and the MRS perform authentication authentication.

During the authentication process, the related interaction process between the MRS and the ASN-GW is forwarded by the BS.

Step 909, the MS sends a registration request to the MRS.

Step 910: After receiving the registration request sent by the MS, the MRS sends a state transition request message to the ASN-GW to perform some information negotiation with the ASN-GW. This message is forwarded to the ASN-GW through the BS.

Step 911: The ASN-GW performs a response process, and sends a state transition response message to the MRS through the BS.

Step 912: After receiving the status transition response message, the MRS sends a registration response message to the MS.

Step 913: The MRS sends a status change confirmation message to the ASN-GW through the BS, indicating that the registration response message has been sent to the MS. This step is an optional step.

Step 914, the MS and the MRS service connection establishment process. In this process, the MRS forwards information through the BS and the ASN-GW.

At this point, the MS completes the relevant network access process. If the MS fails to access the network, the BS updates the group information.

The third MS network access method provided by the embodiment of the present invention can ensure that the access link does not change during the group mobility switching process, and greatly reduces the air interface signaling overhead when the MS is simultaneously switched, thereby reducing the network load. In this solution, the access link and the relay link can be different systems. To use the solution, only the ASN-GW can identify different systems. The program can respond Used in subsequent B3G multiple access network systems.

After the MS accesses the network through the third method, the MS reconnects and the switchover process is still completed through the information exchange with the MRS. The MRS still exchanges information with the ASN-GW through the BS.
