Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and apparatus obtaining transport layer address。
Background technology
Long Term Evolution (LTE, LongTermEvolution) network is by strengthening Radio Access Network (E-UTRAN, EvolvedUTRAN) base station eNB (EvolvedNodeB) in and evolution packet switching center (EPC, EvolvedPacketCore) composition, network flattening。Interface diagram between donor base station shown in Figure 1, base station/MME, including: by the set of the eNB that S1 interface and EPC connect, can be connected by X2 interface between eNB。S1, X2 interface are logic interfacing。One EPC can manage one or more eNB, and an eNB can also be controlled by multiple EPC, and an eNB can manage one or more community。
In order to meet the demand that growing big bandwidth high-speed mobile accesses, third generation partnership project (ThirdGenerationPartnershipProjects, it is called for short 3GPP) release senior Long Term Evolution (LongTermEvolution-advanced is called for short LTE-Advanced) standard。LTE-Advanced is for Long Term Evolution (Long-TermEvolution, it being called for short LTE) evolution of system remains the core of LTE, adopt a series of technology that frequency domain, spatial domain are expanded on this basis, to reach to improve the availability of frequency spectrum, increase the purposes such as power system capacity。Namely wireless relay (Relay) technology is one of technology in LTE-Advanced, it is intended to the coverage of Extended Cell, reduce the area, dead angle in communication, balanced load, the business of transfer hot zones, save the transmitting power of subscriber equipment (UserEquipment is called for short UE) i.e. terminal。
User terminal UE roaming schematic diagram under donor base station/base station as shown in Figure 2, user terminal UE is arranged in base station and covers the community 11 times of lower community 2 and via node (RelayNode is called for short RN), and RN access is the community of donor base station 1 time。The equipment completing relay function is called via node (RelayNode, it is called for short RN), with via node (RelayNode, it is called for short RN) base station that carries out wireless connections is referred to as " donor base station " (DonoreNB, it is called for short DeNB), wireless link between DonoreNB and RN is called back haul link (backhaullink), and its air interface is also referred to as Un interface。Wireless link between RN and UE is called access link (accesslink), and its air interface is also referred to as Uu interface。RN serves as an eNB role for the UE of its service, then serves as a UE role for its DonoreNB。The downlink data of UE business first arrives DonoreNB, then passes to RN, RN again and transmits to UE, on the contrary up then。RN provides the eNB of service as one for the UE under its covering, need to set up X2 with its DeNB to be connected, and only setting up unique X2 to be connected with DeNB, X2 signaling (such as the switching related signaling) exchange between RN and other adjacent eNB is all forwarded by DeNB。That is DeNB act as the role of X2 signaling proxy (X2Proxy)。
In LTE system, neighboring BS relationship Automatic Optimal (ANR, AutomaticNeighborRelation) is a kind of function of self-organization of network self-optimizing, it is possible to automatically carried out the optimization of neighboring BS relationship by network side, improves performance of handoffs。Can reducing manual operation, improve network performance, also can set up X2 and connect between two base station eNB, method is as follows:
As a part for normal call, eNB notifies that peripheral cell is measured by each UE。ENB can adopt distinct methods notice UE measurement, and when report measurement results。
UE detects that community B meets report condition, and UE sends the measurement result about community B。This result comprises community physical token symbol Phy-CID (physicalcellid) of community B。
When eNB receive UE send comprise Phy-CID measurement report, next step will be performed。
ENodeB notifies UE, uses newfound Phy-CID as a parameter to read the Global-CID of relevant adjacent cell, tracking area code (TAC, TrackingAreacode), all available public land mobile network PLMNID。Therefore, eNodeB need to dispatch suitable idling cycle to allow UE read the Global-CID of survey adjacent cell。
When UE gets Global-CID, the UE of adjacent cell, it is reported to eNodeB, the UE of Serving cell also can report the TAC, all PLMNID of surveyed adjacent cell；
ENodeB determines to add this neighboring BS relationship, and Phy-CID and Global-CID can be used to perform following operation:
A searches transport layer address for being newly added eNodeB；
B updates its Neighboring Relation Table；
C is if it is required, then set up new X2 interface to new eNodeB。
In said process, the method obtaining new eNBX2 interface transport layer address is by former eNB transmission eNBCONFIGURATIONTRANSFER to mobile management entity MME (MobilityManagementEntity), the X2 interface transport layer address of the new eNB of acquisition request, MME forwards this to ask by sending MMECONFIGURATIONTRANSFER, new eNB returns to former eNB X2 interface transport layer address by MME after receiving this request。ENBCONFIGURATIONTRANSFER message wherein contains the global Base Station Identification GlobaleNBID of new eNB and former eNB and tracking area identification SelectedTAI (SelectedTrackingAreaIdentity) information of selection, for the routing addressing of this message and subsequent message。SelectedTAI is made up of TAC and PLMN。Here X2 interface transport layer address refers to the eNB transport layer address for X2 SCTP (SCTP, StreamControlTransmissionProtocol) end points。
In said process, X2 interface can be set up between two eNB connect, but under Relay framework, if eNB is found that the community cell1 below RN, and eNB needs to set up X2 mouth with RN, because the X2 signaling between RN and other adjacent eNB (such as switching related signaling) exchange is all forwarded by donor base station DeNB, then the donor base station DonoreNB having only to eNB and RN sets up X2 mouth。
In LTE system, the transport layer address of the other side between eNB, can be obtained by UE, but in lte-a system, owing to donor base station adds RN, after UE detects the community under RN, eNB cannot pass through RN and obtain the transport layer address of donor base station, connects thus X2 mouth cannot be set up。
