Technical field

The present invention relates to communication technical field, more particularly to a kind of carrier polymerizing method, relevant device and system.

Background technology

With the development of GSM, the service quality more and more higher that system can be provided.To keep 3GPP long term competitive advantage, LTE Release-12 standard formulation work is carried out.One key property of Release-12 versions is to support the carrier aggregation (CA between base station, Carrier Aggregation), that is user equipment (User Equipment, UE) it can be communicated simultaneously using the multiple cells for belonging to multiple base stations, so as to support high speed data transfer, UE hardware circuit solution is improved.Current discussion problem of this feature in standard is dual link (DC, Dual Connectivity for LTE) or cell enhancing (SCE, Small Cell Enhancement).

For a UE, in this multiple serving BS, one of them is master base station (MeNB, Master eNB), and other are prothetic group station (SeNB, Secondary eNB).Master base station and prothetic group station can all carry out data transmission with UE, both main difference is that, master base station undertakes more control functions, such as has S1-MME connections between master base station and MME, all S1-MME signaling terminating is in MeNB, that is, being related to the interaction of signaling between MME has master base station to be responsible for completion；In addition, the control signaling (RRC information) that master base station is responsible for air interface UE between is interacted, if prothetic group station needs the RRC configuration parameters at modification prothetic group station, master base station must be asked, via master base station eat dishes without rice or wine change.

It can be divided into three kinds for bearer types：One kind is：MCG (Master Cell Group, main plot group) is carried, and the data of the carrying are directly transmitted by MeNB between UE and gateway SGW；It is for second：SCG (Secondary Cell Group, secondary cell group) is carried, and the data of the carrying are transmitted by SeNB between UE and SGW；The third is：Split Bearers, shunting carrying, the data of the carrying between MeNB and SeNB and UE simultaneously by transmitting, and transmitted between MeNB and SGW.For example：For downlink data, downlink data first reaches MeNB by S1-U, and MeNB determines shunting partial data and is transferred to SeNB by X2-U, and the partial data is handed down to UE by SeNB.Data on current SGW and eNB S1-U, MeNB and SeNB X2-U interfaces are transmitted by GTP (General Packet Radio System Tunnelling Protocol, General Packet Radio System tunnel protocol).Each The up or downlink data of carrying has single GTP tunnel, is distinguished by TEID (Tunnel Endpoint IDentifier r, Tunnel End Point Identifier).

According to 3GPP TS 23.007 regulation, MeNB and SeNB have S1-U to be connected between SGW, i.e. MCG carryings and SCG carryings.But SGW will not recognize bearer types (MCG or SCG carryings), i.e., carrier aggregation technology is transparent to SGW between base station.When SeNB or MeNB detect the GTP mistakes that a SCG is carried, GTP Error Indication (instruction of GTP mistakes) are sent to SGW, SGW will not only delete involved carrying, but delete and be carried on all TEID of interior all UE comprising MCG, and downlink data notification message (Downlink Data Notification) is sent to MME, style of writing release flow on MME triggerings UE, and attempt to rebuild to UE, that is, beep-page message is sent to UE.Subject matter caused by prior art is, when no matter GTP mistakes occur for any one carrying in MCG carryings or SCG carryings, will all to cause the Connection Release of all carryings and UE, will have a strong impact on Consumer's Experience.
