Fig. 7 is the schematic diagram of one embodiment of the configuration method of Base Station Identification according to the present invention, as shown in Figure 7:
Step 301, macro base station judges whether to be configured as opening base station mode of extension.
Step 302, if be configured as open base station mode of extension, macro base station according to preset configuration information generate by 3rd eNB ID of the first basic Base Station Identification and extended base station mark composition, the first basic occupied bit number of Base Station Identification For N, extended base station identifies the extended bit number W that occupied bit number is network management system configuration.
Step 303, if it is not, then macro base station generates the 4th eNB ID according to preset configuration information, the 4th eNB ID is only Bit number including occupancy is the second basic Base Station Identification of N.
Step 304, macro base station is asked to the S1 interface foundation that core net transmission carries the 3rd eNB ID or the 4th eNB ID It asks.
Step 305, core net returns to S1 interface and establishes response message, and notice S1 interface establishes result and for third The verification result of eNB ID or the 4th eNB ID.
The configuration method of Base Station Identification in above-described embodiment, it is real by the cell ID for occupying one or more bit The dilatation of existing Base Station Identification, cell ID accordingly reduce same bit number, and basic Base Station Identification and extended base station are identified Request message is established by S1 and is indicated to core net, and whether core net is checked with existing Base Station Identification after receiving and deposited Basic Base Station Identification part and extended base station identification division are recorded in the case where repeating for there is no conflict, and will matching The result notice of inspection is to source base station.
Based on current communication standard, eNB ID has 20 bits, and Cell ID occupies 8 bits.To Base Station Identification address After carrying out dilatation, the eNB ID of original 20 bits is basic Base Station Identification, occupies in 8 bits from Cell ID and separates 1 Or multiple bits, it is identified as extended base station.First basic Base Station Identification and the second basic occupied bit number of Base Station Identification It is all 20 bits.
