Problems solved by technology

[0018] In these two scenarios, there are two different connections for the MN at the same time. In the prior art, whether it is the existing PMIP technology or the modified PMIP mechanism, for PMIP registrations from different MAGs or different interfaces, the LMA / MAPS will assign different HNPs, so business continuity cannot be guaranteed

Embodiment 1

[0090] Figure 7 It is the first embodiment of the multi-connection establishment method of the present invention. This embodiment is applicable to when the MN initiates the connection establishment, and the MAPS-MN queries the connection status of the MN in the original MAG1-MN. Such as Figure 7 As shown, it specifically includes the following steps:

[0091] Step 701, after the MN accesses the PMIPv6 domain through the attachment process, it sends a routing request (RS, Router Solicitation) message to the MAG1-MN it belongs to. This step is optional.

[0092] Step 702, MAG1-MN is triggered by step 701, or triggered by the mobile network during the access process, MAG1-MN sends a proxy binding update (PBU, Proxy Binding Update) message to MAPS-MN, instead of MN registering with MAPS-MN, The message carries the MN identification (MN ID) and the proxy broadcast address CoA1 assigned by the MAG1-MN to the MN. The address of MAG1-MN is also sent to MAPS-MN in this message. ...

Embodiment 2

[0107] Figure 8 It is the second embodiment of the multi-connection establishment method of the present invention, and this embodiment is applicable to the MAPS-MN obtaining the multi-access indication from the authentication server. Such as Figure 8 As shown, it specifically includes the following steps:

[0108] In steps 801 and 802, the MN needs to first access the PMIPv6 domain through the access process and the access authentication process before performing PMIP registration and establishing an IP connection. During this process, different PMIPv6 domains will have different specific access procedures and access authentication procedures, and the specific exchanged messages may be different, but the completed functions are the same. Authentication servers may also have different names in different PMIPv6 domains, such as HSS in 3GPP, AAA in WiMAX, etc., which are collectively referred to as authentication servers in the present invention. The access process in step 8...

Embodiment 3

[0128] Figure 9 It is the third embodiment of the multi-connection establishment method of the present invention, and this embodiment is applicable to the MAPS-MN obtaining the multi-access indication from the authentication server. This embodiment and Figure 8 The difference is that the access process and access authentication process in some PMIPv6 domains are not carried out through the MAG, but through another network element (authenticator), such as in 3GPP, through the mobility management entity (MME), at this time, the registration process of PMIPv6 is performed by the authenticator triggering the MAG. Such as Figure 9 As shown, it specifically includes the following steps:

[0129] Steps 901, 902 are the same as steps 801, 802.

[0130] Step 903, authenticator 1 sends a connection establishment trigger message to MAG1-MN, triggering MAG1-MN to initiate a PMIPv6 registration process.

[0131] Steps 904-911 are the same as steps 803-810.

[0132] In step 912, th...

Abstract

The invention provides a multi-access connection establishment method. The multi-access connection establishment method comprises the step of distributing a hometown network prefix the same as the other connections established by a mobile node for the connection being established by the mobile node when the mobile node is accessed from a mobile access gateway and a mapping server judges the access state of the mobile node as a multi-access state. The invention further provides the mapping server and a multi-access connection establishment system. The multi-access connection establishment method, the system and the mapping server are capable of establishing a new connection accurately and retaining the original connection.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-access connection establishment method, system and mapping server. Background technique [0002] Transmission Control Protocol / Internet Protocol (TCP / IP), in the initial design, did not consider the situation that the topology position of the terminal will change, that is, the TCP / IP protocol itself does not support mobility. In the traditional TCP / IP network environment, IP provides the routing function for the Internet (Internet). It assigns logical addresses, that is, IP addresses, to all nodes (including hosts and routers), and each port of each host is assigned an IP address. An IP address includes a network prefix and a host part. The IP addresses of all hosts on the same link usually have the same network prefix but different host parts. This enables IP to perform route selection based on the network prefix part of the IP address of the destination node, so th...
