AGR carries out decapsulation to the data message and handles when receiving the data message that mails to the terminal, peels off the heading that comprises RID newly-increased in the data message, mails to the terminal.
The major function of GSR is to carry out routing and transmit data message according to the route station location marker RID in the data message.
IDMS mainly is responsible for the mapping relations of User Identity and station location marker in the maintaining network, and to IAD router and other mapping server inquiry service is provided.
Authentication center is responsible for information such as recording user classification, user's grade of service, when the user inserts, the user is carried out the legitimacy authentication and authorization.Bi-directional authentification between authentication center's network enabled and user.
Wireless access network is responsible for providing and two layers of link between the IAD router-A GR are arrived at the maintenance customer terminal; In the cellular mobile network application scenarios, be responsible for RRM.
The method that under the above-mentioned network architecture, realizes the handover management that mobility is supported is described below, Correspondent Node of mobile node (Correspondent Node is called for short CN) and mobile node (Mobile Node; Be called for short MN) set up and communicate by letter; Each other the transceive data message is being set up in the process of correspondence with MN, the AID that the AGR at CN place carries in can the message according to MN; Inquire about the AID of MN and the mapping relations of RID to mapping server IDMS, thereby obtain the route station location marker RID of MN; The AGR at CN place is at AID and the RID mapping relations table (abbreviation mapping table) of local maintenance MN simultaneously, and form is as shown in the table:
The opposite end identity station location marker mapping table of table 1 IAD router
| AID1 | RID1 |
| AID2 | RID2 |
| ... | ... |
Detect the mobility (variation has taken place in the position that is MN, has moved to another AGR from an AGR coverage, need initiate switching flow in this case) of MN when wireless access network after, trigger switching flow.In handoff procedure, cut out gateway A GR and set up the relation of forwarding with incision gateway A GR, in handoff procedure or switch accomplish after, cut out the data message forwarding that mails to MN that gateway A GR will receive and give incision gateway A GR, GR is transmitted to MN by the incision gateway A.
Route detour problem after switch, switch accomplish after, the new mapping relations of MN are notified the IAD router at all CN places by the incision gateway.Like this, the IAD router at CN place just can directly send to follow-up message the incision gateway of MN, has avoided route circuitous.
Therefore, need be the information that each local MN that inserts preserves all CN just at the IAD router, according to the information of preserving, the sign mapping relations that MN is new are notified the IAD router to the CN place.
In practical implementation; At first require the IAD router can preserve the record of the Correspondent Node of all local user terminals that insert (being called for short the opposite end table), next requires the couple in router that all IAD routers can the access of notifying communication opposite end separately or under the help of mapping server.If mapping server can not provide the help of transmitting notice, the IAD router just must be preserved the information of the IAD router at Correspondent Node place so.Table 2 and table 3 are a kind of organizational forms that mapping table and Correspondent Node mapping table are inserted in this locality of IAD router preservation in this case.
The local access terminal identification mapping table of table 2 IAD router
The Correspondent Node sign mapping table of table 3 IAD router
| Opposite end AID1 | Opposite end RID1 | The IAD router of Access Network | Timer |
In table 2 and table 3, the record of Correspondent Node also need be provided with timer, just should delete the record of this Correspondent Node if decide not have for a long time to have communicated by letter with this Correspondent Node, to save memory headroom.
Mainly there is following problem in above solution:
