Embodiment
The embodiment of the invention has Proxy ND (Proxy NeighborDiscovery in the setting of Access Network side apparatus; Neighbours find the agency) entity of function; This support neighbours find that Access Network side apparatus and the user equipment (UE) of acting on behalf of Proxy ND function carry out information interaction, with the survival detection of the IPv6 session between the Access Network side apparatus that carries out said UE and said support Proxy ND function.The Access Network side apparatus of this support Proxy ND function is used to act on behalf of destination node, carries out information interaction with source node; Said destination node comprises: the node of supporting the Access Network side apparatus place of Proxy ND function itself; Said source node comprises: said UE perhaps supports the node at the Access Network side apparatus place of Proxy ND function itself.
The Access Network side apparatus of this support Proxy ND function is used to act on behalf of destination node, with its employed MAC (address of on the medium Access Layer, using) address, replys NS (neighbor request) message that source node is initiated through NA (neighbours' advertisement) message; Perhaps, the Access Network side apparatus of this support Proxy ND function is used to act on behalf of destination node and initiates NS message to source node, and the NA of reception sources node replys, and obtains the MAC Address of source node.
When utilizing Proxy ND to detect with the survival of supporting the IPv6 session; Then source node is that the subscriber of IPv6 session belongs to node or IPv6 RG (user gateway) or IPv6 AN (access point) or IP fringe node, and destination node can be IP fringe node itself or another user.
One embodiment of the present of invention are the method that a kind of survival of IPv6 session detects; As shown in Figure 1; For UE initiates the situation that survival detects, the IPv6 session of the embodiment of the invention is at IPv6 BNG (IPv6Broadband Network Gateway, IPv6 wideband network gateway) or IPv6 BRAS (IPv6Broadband Remote Access Server; The IPv6 BAS Broadband Access Server) termination; Originate in the IPv6 subscriber, the subscriber is the user's (representing with UE (UserEquipment, subscriber equipment) among the figure) after user gateway or the user gateway.Suppose that IPb is the IPv6 address of IPv6 wideband network gateway or BAS Broadband Access Server or the user's under IPv6 wideband network gateway or the BAS Broadband Access Server IPv6 address.
The embodiment of the invention is supported Proxy ND function on IPv6 wideband network gateway or BAS Broadband Access Server, corresponding IPv6 Session Keepalive (survival of IPv6 session detects) flow process is following:
User after step 1-3, user gateway or the user gateway initiates NS message, the corresponding MAC Address in IPv6 address (like IPb) that comprises in request and the NS message;
User gateway and access point transfer NS; This NS message can adopt the mode of clean culture to send, and also can adopt the mode of broadcasting to send;
The Proxy ND functional entity of step 4, IPv6 wideband network gateway or BAS Broadband Access Server is through the MAC Address (MACb) of NA message with oneself, and the node at Agent IP b place is replied the NS message that receives;
Step 5-6, access point and user gateway transfer NA message arrive the user at last, and the user can confirm the IPv6 session survival thus.
Above process can periodically be carried out, and the IPv6 session survival is carried out periodicity detect.
An alternative embodiment of the invention is the method that a kind of survival of IPv6 session detects; As shown in Figure 2; Be the situation of IPv6 BNG or IPv6 BRAS initiation survival detection, the embodiment of the invention is supported Proxy ND function on IPv6 wideband network gateway or BAS Broadband Access Server.
Fig. 2 is with the different of Fig. 1: Fig. 2 is that IPv6 wideband network gateway or BAS Broadband Access Server are initiated the detection of IPv6 session survival.Suppose that IPa is IPv6 wideband network gateway or the BAS Broadband Access Server user's that will detect IPv6 address.
The survival testing process of corresponding IPv6 session is following:
Step 1-3, IPv6 wideband network gateway or BAS Broadband Access Server are initiated NS message, the corresponding MAC Address in IPv6 address (like IPa) that comprises in request and the NS message;
User gateway and access point transfer NS; This NS message can adopt the mode of clean culture to send, and also can adopt the mode of broadcasting to send;
Step 4, user reply the NS message that receives through the MAC Address (MACa) of NA message with oneself;
Step 5-6, access point and user gateway transfer NA arrive IPv6 wideband network gateway or BAS Broadband Access Server at last, and IPv6 wideband network gateway or BAS Broadband Access Server can be confirmed the IPv6 session survival thus.
Above process can periodically be carried out, and the IPv6 session survival is carried out periodicity detect.
An alternative embodiment of the invention is the method that a kind of survival of IPv6 session detects, like Fig. 3, shown in Figure 4, for initiated the situation of NS by the user.In the present embodiment; Except on the IPv6 of Access Network side wideband network gateway or BAS Broadband Access Server, supporting Proxy ND; Also can further go up support Proxy ND function at IPv6 user gateway (as shown in Figure 3) or IPv6 access point (as shown in Figure 4); Like this, this IPv6 user gateway or IPv6 access point are replied the MAC Address of oneself respectively to the user.The survival testing process of IPv6 session shown in Figure 3 is following:
