Embodiment
When the embodiment of the invention is determined SCTP link establishment conflict in setting up the X2 connection procedure, the relatively sign of self and the relatively sign of opposite end are compared; According to comparative result, when determining self to be client, send X2 to the opposite end and set up request message; According to comparative result, when determining self to be service end, the X2 that receives from the opposite end sets up request message.Owing to when the embodiment of the invention can clash in the mode of operation of two eNB, carry out the negotiation that X2 connects, set up request message thereby avoid sending to the opposite end simultaneously between two eNB X2.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 2, the negotiating system of embodiment of the invention X2 connection comprises: first base station 10 and second base station 20.
First base station 10, be used for when second base station 20 is set up the X2 connection procedure and determined that the SCTP link establishment conflicts, the relatively sign of self and the relatively sign of second base station 20 are compared, according to comparative result, when determining self to be client, send X2 to second base station 20 and set up request message, according to comparative result, when determining self to be service end, the X2 that receives from second base station 20 sets up request message.
Second base station 20, when being used for setting up the X2 connection procedure in first base station 10 and determining SCTP link establishment conflict, the relatively sign of self and the relatively sign of first base station 10 are compared, according to comparative result, when determining self to be client, send X2 to first base station 10 and set up request message, according to comparative result, when determining self to be service end, the X2 that receives from first base station 10 sets up request message.
In specific implementation process, SCTP link establishment conflict can be determined according to following manner in first base station 10 and second base station 20:
First base station 10 and second base station 20 send INIT (SCTP is initial) message to the opposite end, and receive the INIT message of opposite end, then determine SCTP link establishment conflict.
Need to prove that the embodiment of the invention is not limited to the mode of above-mentioned definite SCTP link establishment conflict, other modes that can determine SCTP link establishment conflict all are suitable for the embodiment of the invention.
Wherein, the relatively sign of the embodiment of the invention comprises PLMN ID (Public Land MobileNetwork ID, public land mobile network's sign) time, first base station 10 compares the PLMN ID of self and the PLMN ID of second base station, and determines it self is client or service end according to the size of PLMN ID.
Suppose that the bigger side of PLMN ID is client, a less side is service end, then first base station 10 compares the PLMN ID of self and the PLMN ID of second base station 20, when comparative result is that self PLMN ID is during greater than the PLMN ID of second base station 20, determine it self is client, when comparative result is self PLMN ID during less than the PLMN ID of second base station 20, determine it self is service end; Accordingly, second base station 20 compares the PLMN ID of self and the PLMN ID of first base station 10, when comparative result is that self PLMN ID is during greater than the PLMN ID of first base station 10, determine it self is client, when comparative result is self PLMN ID during less than the PLMN ID of first base station 10, determine it self is service end.
Suppose that the less side of PLMN ID is client, a bigger side is service end, then first base station 10 compares the PLMN ID of self and the PLMN ID of second base station 20, when comparative result is that self PLMN ID is during less than the PLMN ID of second base station 20, determine it self is client, when comparative result is self PLMN ID during greater than the PLMN ID of second base station 20, determine it self is service end; Accordingly, second base station 20 compares the PLMN ID of self and the PLMN ID of first base station 10, when comparative result is that self PLMN ID is during less than the PLMN ID of first base station 10, determine it self is client, when comparative result is self PLMN ID during greater than the PLMN ID of first base station 10, determine it self is service end.
Specifically be the less side of PLMN ID as client or a bigger side can set as required as client, but the base station that needs to guarantee two ends is consistent.
The Bit String that PLMN ID is made up of the moving national code of 3 displacements and the moving network code of 3 displacements, each digital span is 0～9.When comparing two PLMN ID, can adopt following manner of comparison:
Compare by turn from high to low, till difference appearred in numerical value, the PLMN ID of numerical value the greater was bigger.
For example: certain PLMN1 ID of operator is 086001, and the PLMN2 ID of another operator is 086011.At first compare highest order (left side is played the 1st), two ID are " 0 ", equate, compare next bit, and two PLMNID are " 8 ", and are equal ... that the rest may be inferred, and relatively the 5th, because 1＞0, so determine PLMN2 ID＞PLMN1 ID.
The size that can certainly directly compare numerical value.
Because the Bit String that PLMN ID is made up of the moving national code of 3 displacements and the moving network code of 3 displacements, the identical situation of PLMN ID that two base stations might occur, in order also to hold consultation better when above-mentioned solution occurs, relatively sign can also comprise eNB ID (Base Station Identification).
Suppose that the bigger side of eNB ID is client, a less side is service end, when the PLMNID of self equals the PLMN ID of second base station 20, first base station 10 further compares the eNB ID of self and the eNB ID of second base station 20, when comparative result is that self eNB ID is during greater than the eNB ID of second base station 20, determine it self is client, when comparative result is self eNB ID during less than the eNB ID of second base station 20, determine it self is service end; Accordingly, second base station 20 further compares the eNB ID of self and the eNB ID of first base station 10, when comparative result is that self eNB ID is during greater than the eNB ID of first base station 10, determine it self is client, when comparative result is self eNBID during less than the eNB ID of first base station 10, determine it self is service end.
Suppose that the less side of eNB ID is client, a bigger side is service end, when the PLMNID of self equals the PLMN ID of second base station 20, first base station 10 further compares the eNB ID of self and the eNB ID of second base station 20, when comparative result is that self eNB ID is during less than the eNB ID of second base station 20, determine it self is client, when comparative result is self eNB ID during greater than the eNB ID of second base station 20, determine it self is service end; Accordingly, second base station 20 further compares the eNB ID of self and the eNB ID of first base station 10, when comparative result is that self eNB ID is during less than the eNB ID of first base station 10, determine it self is client, when comparative result is self eNBID during greater than the eNB ID of first base station 10, determine it self is service end.
Specifically be the less side of eNB ID as client or a bigger side can set as required as client, but the base station that needs to guarantee two ends is consistent.
ENB ID is under same PLMN, the unique identification of base station.Therefore two situations that eNB ID is identical can not appear.
ENB ID is 20 signless integer, and is relatively similar with PLMN ID to it, do not repeat them here.
Be to compare by PLMN ID earlier above, when PLMN ID is identical, compare by eNB ID again.In specific implementation process, also can directly compare by eNB ID.Concrete, relatively sign comprises eNB ID.
