Below in conjunction with accompanying drawing above-mentioned each preferred embodiment is described in detail.
In the present embodiment; Relay is connected in the process of foundation at S1 with Donor eNodeB; Set up the Relay community configured information is carried at the S1 interface that to send to host's node in the request message be example; Describe the acquisition methods of above-mentioned community configured information, as shown in Figure 7, the acquisition methods of this community configured information comprises the steps:
The S1:Relay node carries community configured information in S1 Setup Request message; The Relay community configured information is sent to Donor eNodeB (being equivalent to above-mentioned host's node); This community configured information can comprise: the physical-layer cell identifier of Relay node Serving cell (Physical Cell Identifier; Abbreviate PCI as), Cell Global Identity (the E-UTRAN Cell Global Identifier of evolution; Abbreviate ECGI as), tracking area coding information such as (Tracking Area Code abbreviate TAC as).
The community configured information of the Relay node of each connection of S2:Donor eNodeB record
When S3:Donor eNodeB receives the handoff request message of MME or other eNodeB transmission, do as judging:, then directly handle this handoff request message if the cell information that carries in the handoff request message is the Serving cell of Donor eNodeB oneself; If the cell information that carries in the handoff request message is not the Serving cell of Donor eNodeB oneself, judge then whether the cell information that carries in the handoff request message is the sub-district of Relay node; If the cell information that carries in the handoff request message is the sub-district of Relay node, then handoff request message is sent to this Relay node.
S4:, then abandon this handoff request message if the cell information that carries in the handoff request message is not the Relay message that this Donor eNodeB connects down.
In the present embodiment; Relay and Donor eNodeB are in S1 config update process; The Relay community configured information is carried to send to host's node in the S1 configuration update message be example; Describe the acquisition methods of above-mentioned community configured information, as shown in Figure 8, the acquisition methods of this community configured information comprises the steps:
The S1:Relay node carries the cell configuration lastest imformation in ENB CONFIGURATION UPDATE message (S1 configuration update message); Relay cell configuration lastest imformation is sent to Donor eNodeB (being equivalent to above-mentioned host's node), and this cell configuration lastest imformation can comprise: information such as the PCI of Relay node Serving cell, ECGI, TAC.
S2:Donor eNodeB upgrades the community configured information of corresponding Relay node.
When S3:Donor eNodeB receives the handoff request message of MME or other eNodeB transmission, do as judging:, then directly handle this handoff request message if the cell information that carries in the handoff request message is the Serving cell of Donor eNodeB oneself; If the cell information that carries in the handoff request message is not the Serving cell of Donor eNodeB oneself, judge then whether the cell information that carries in the handoff request message is the sub-district of Relay node; If the cell information that carries in the handoff request message is the sub-district of Relay node, then handoff request message is sent to this Relay node.
S4:, then abandon this handoff request message if the cell information that carries in the handoff request message is not the Relay message that this Donor eNodeB connects down.
In the present embodiment; Relay adopts newly-increased message, and to send to host's node in the newly-increased message of S1 interface be example so that the Relay community configured information is carried at, and describes the acquisition methods of above-mentioned community configured information; As shown in Figure 9, the acquisition methods of this community configured information comprises the steps:
The S1:Relay node carries community configured information in ENB CONFIGURATION UPDATE message (the S1 interface increases message newly); Relay cell configuration lastest imformation is sent to Donor eNodeB (being equivalent to above-mentioned host's node), and this cell configuration lastest imformation can comprise: the PCI of Relay node Serving cell, ECGI, TAC information.
S2:Donor eNodeB preserves the community configured information of corresponding Relay node.
When S3:Donor eNodeB receives the handoff request message of MME or other eNodeB transmission, do as judging:, then directly handle this handoff request message if the cell information that carries in the handoff request message is the Serving cell of Donor eNodeB oneself; If the cell information that carries in the handoff request message is not the Serving cell of Donor eNodeB oneself, judge then whether the cell information that carries in the handoff request message is the sub-district of Relay node; If the cell information that carries in the handoff request message is the sub-district of Relay node, then handoff request message is sent to this Relay node.
S4:, then abandon this handoff request message if the cell information that carries in the handoff request message is not the Relay message that this Donor eNodeB connects down.
From above description; Can find out; The present invention has realized following technique effect: host's node receives the community configured information that via node sends through the S1 interface, and preserves, and promptly obtains the community configured information of via node through the S1 interface; Avoided connecting under the still unfounded situation at X2; Host's node can't obtain the phenomenon of the community configured information of via node, thus the method that provides another kind of host's node to obtain the community configured information of via node, the flexibility that has improved the community configured information of host's node acquisition via node.Simultaneously; Receive at host's node under the situation of handoff request message, host's node can be confirmed the purpose via node that switch the sub-district according to the community configured information that has obtained through the S1 interface and preserve, and handoff request message is sent to this purpose via node; Avoided connecting under the still unfounded situation at X2; Host's node can't be confirmed the phenomenon of purpose via node, thereby has improved the accuracy that host's node is confirmed destination node, has improved the correctness that handoff request message is sent.
