Embodiment
For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the embodiment of the invention is further described.
In the embodiment of the invention, the parameter of abutting subdistrict list comprises cell ID, can also include but not limited to: the combination in any of type, bandwidth, frequency, the type network type that can express support for wherein: circuit domain, or packet domain, or circuit domain and packet domain, the type can also be represented the type of sub-district: base station from home sub-district or macrocell etc.
The embodiment of the invention provides a kind of method that sends abutting subdistrict list, as shown in Figure 1, does not have X2 interface between eNB1 among the LTE and the eNB2, sub-district cell1 among the eNB1 and the cell2 among the eNB2 have syntople, as shown in Figure 2, the schematic flow sheet for the embodiment of the invention comprises:
Step 201, eNB1 are to mobile management entity 1 (Mobility Management Entity, MME1) send first message, this first message is carried the abutting subdistrict list of cell1, and the information of indication eNB2, and this information can include but not limited to: the sign ID of eNB2.
In this step, if also do not set up the S1 interface between eNB1 and MME1, then first message connects the request of foundation for the S1 interface, if the S1 interface between eNB1 and MME1 is set up, then first message is S1 interface updating message, perhaps other S1 interface messages.
Step 202, MME1 receive first message, find MME2 under the eNB2 according to the information of indication eNB2, send the S10 interface message to MME2, are used for transmitting first message.
In the present embodiment, S10 message can be the message that exists at present, and at this moment, (Information Element IE) is carried in this message and sends, or a newly-increased S10 message as a cell with first message.
Step 203, MME2 receive first message, send second message of carrying above-mentioned abutting subdistrict list to eNB2.
In this step, if also do not set up the S1 interface between MME2 and eNB2, MME is carried at the S1 interface with abutting subdistrict list and sets up and issue eNB2 in the request message, perhaps, MME2 buffer memory first message is when the S1 interface is set up in the eNB2 request, MME2 is carried at abutting subdistrict list in the S1 interface foundation response and sends to eNB2, if the S1 interface between MME2 and eNB2 is set up, then second message is S1 interface updating message, or other S1 interface messages.
In the embodiment of the invention, MME1 and MME2 can be same MME, at this moment, do not need the forwards step between MME.
In the embodiment of the invention, the LTE internal system, do not comprise sub-district if having among the eNB of X2 interface with syntople, can be by the interface between eNB and MME, and the interface between MME sends abutting subdistrict list, avoid the manual configuration abutting subdistrict list, improved the efficient of abutting subdistrict list configuration.
The embodiment of the invention provides the method for another kind of transmission abutting subdistrict list, be specially LTE system and global system for mobile communications (Universal Mobile Telecommunications System, UMTS) transmit the method for abutting subdistrict list between, triggering this flow process with the eNB among the LTE is example, be illustrated in figure 3 as the schematic flow sheet of the embodiment of the invention, comprise:
Step 301 is similar with step 201, and just in the embodiment of the invention, the indication information that first message is carried is indication radio network controller (Radio Network Controller, information RNC).
Step 302, MME receive first message, obtain abutting subdistrict list, find the core network entity of above-mentioned RNC correspondence according to indication information: service universal grouping wireless business supporting node (ServingGeneral Packet Radio Service Supporting Node, SGSN), and, be used for transmitting first message to this SGSN transmission S3 interface message.
Step 303, SGSN receive first message, obtain abutting subdistrict list, send second message to RNC, and this second message is carried above-mentioned abutting subdistrict list.
In this step, above-mentioned second message is the Iu interface message, it can be the Iu interface message that increases newly, or existing Iu interface message, for example, message transmission is indicated (INFORMATIONTRANSFER INDICATION) message or other message, abutting subdistrict list is carried in this message as a cell IE send.
In the embodiment of the invention, also can trigger this flow process by RNC, concrete enforcement is similar with the method for present embodiment, does not repeat them here.
The embodiment of the invention is transmitted abutting subdistrict list by message between the RNC of the eNB of LTE and UMTS, avoided the manual configuration abutting subdistrict list, has improved the efficient of configuration abutting subdistrict list.
The embodiment of the invention provides the method for another kind of transmission abutting subdistrict list, be specially LTE system and whole world mobile communcations system (Global System for Mobile communications, GSM) transmit the method for abutting subdistrict list between, triggering this flow process with the eNB among the LTE is example, be illustrated in figure 4 as the schematic flow sheet of the embodiment of the invention, comprise:
Step 401 is similar with step 201, and just in the embodiment of the invention, the indication information that first message is carried is indication base station sub-system (Base Station Subsystem, information BSS).
Step 402 is with step 302.
Step 403, SGSN send second message to BSS, and this second message is carried the abutting subdistrict list that comprises in first message.
In this step, second message is the Gb/A interface message, it can be the Gb/A interface message that increases newly, or an existing Gb/A message, for example, resource request (RESOURCE REQUEST) message, or resource indication (RESOURCE INDICATION) message, perhaps there is not link information (CONNECTIONLESS INFORMATION) message, or other message, abutting subdistrict list is carried in this message as an IE.
In this step, also can trigger this flow process by BSS, the method for concrete grammar and present embodiment is similar, does not repeat them here.
Method of the invention process be suitable for equally and RNC and BSS between the transmission of abutting subdistrict list, utilize the Iu interface between RNC and the SGSN this moment, and the transmission of the Gb/A interface between BSS and SGSN abutting subdistrict list, concrete grammar and the foregoing description are similar, do not repeat them here.
The embodiment of the invention is transmitted abutting subdistrict list by message between the BSS of the eNB of different system LTE and GSM, avoided manual configuration, has improved the efficient of abutting subdistrict list configuration.
The embodiment of the invention provides the method for another kind of transmission abutting subdistrict list, Figure 5 shows that the system construction drawing of the embodiment of the invention, there is not X2 interface between eNB1 in the LTE system and the eNB2, sub-district cell1 among the eNB1 and the cell2 among the eNB2 have syntople, Automatic Configuration Server, promptly (Self-Organization Network SON) manages eNB self-organizing network, be illustrated in figure 6 as the schematic flow sheet of the embodiment of the invention, comprise:
Step 601, eNB1 send first message to SON, and this first message is carried the abutting subdistrict list of cell1, and the information of indication eNB2, and this indication information can include but not limited to: the ID of eNB2.
Step 602, SON receive first message, obtain abutting subdistrict list, and send above-mentioned abutting subdistrict list according to indication information to eNB2.
