Description

The processing method and processing device of cell connection failure

Technical field

The present invention relates to the communications field, in particular to a kind of processing method and processing device of cell connection failure.

Background technology

Due to current long evolving system (Long Term Evolution, referred to as LTE) system using elder generation in source Cell disconnects, and then establishes switching method (the i.e. break-before-make, after first interrupting of connection in Target cell again Establish).The transmitting-receiving that business datum can be produced is interrupted.Therefore third generation mobile Partnership Program (3rd Generation Partnership project, referred to as 3GPP) discussion group provides new scheme and is used for while keeps user equipment (User Equipment, referred to as UE) cell-of-origin and Target cell connection (i.e. make-before-break, first establish after in It is disconnected).Interrupt latency is changed for reducing UE lateral incisions.

It is as shown in Figure 1 hand off signaling flow chart：The make-before-break schemes are described as follows：

Step 1：UE reporting measurement reports (Measurement Report) give Internet.

Step 2：Source base station (Source enode bs (Evolved Node B:, referred to as eNB)) send handover request (Handover Request) gives target BS (Target eNB).

Step 3：Target BS agrees to switching, replys Handover Request Acknowledge (Handover Request Acknowledge)。

Step 4：Source base station sends switching command and reconfigured to UE, i.e. RRC connections (RRCConnectionReconfiguration) message.UE, which is received, remains in that (or source is small with source base station after switching command Area) connection do not discharge, retain cell-of-origin be configured to safeguard with the connection of cell-of-origin, preserve being configured to for Target cell The follow-up connection established with target BS (or Target cell).UE is initiated in mesh while keeping and cell-of-origin data transfer The access procedure of cell is marked, carries out the down-going synchronous of Target cell.

Step 5a/5b:Source base station initiates data forwarding process, sends numbering state transfer information (5a.SN Status Transfer target BS) is given, and gives data forwarding (5b.Data forwarding) to target BS.

Step 6：UE initiates the random access procedure in Target cell, such as passes through Physical Random Access Channel (Physical Random Access Channel, referred to as PRACH) channel transmission up leading (peamble).

Step 7：Target BS replys accidental access response message (Random Access Response to UE:, referred to as RAR)。

Step 8：UE sends RRC connections configuration completion message (RRCConnectionReconfigurationComplete) To Target cell.

Step 9：Target BS instruction source base station release eats dishes without rice or wine to be connected with UE's, i.e. UE contexts release (UE Context Release) message.

The failure handling of single connection is illustrated below：

Single connection refers to UE only and there is a connection base station, including a PCell or additionally includes one or more secondary cells (Secondary Cell, referred to as SCell).The failure of single connection includes following 2 class：Radio Link Failure：Including following 3 kinds Subtype：

Physical layer lock-out (such as timer t310 time-out).

The random access failure (such as reaching largest random access attempts number) of MAC layer.

Rlc layer reaches maximum retransmission instruction (such as reaching maximum rlc layer maximum retransmission).

Handoff failure：Switching (such as timer t307 time-out) is not successfully completed at the appointed time.

The connection failure processing to dual link (Dual Connectivity, referred to as DC) illustrates below：

Dual link (DC) function is introduced in LTE system, DC includes two small district's groups：Main plot group (Master Cell Group, referred to as MCG) and secondary cell group (Secondary Cell Group, referred to as SCG).Wherein MCG includes one PCell additionally includes one or more SCell, and secondary cell group (Secondary Cell Group, referred to as SCG) includes one Individual main auxiliary cell (Primary Secondary Cell, referred to as PSCell) additionally includes one or more SCell.Change Become caused failure Radio Link Failure same as above during main plot (Primary Cell, referred to as PCell) and cut Change unsuccessfully.Unsuccessfully include caused by during change PSCell：

Radio Link Failure (wherein physical layer lock-out unsuccessfully shows as timer t313 time-out)；

The change failure of secondary cell group (is not successfully connected target PSCell, shows as timer t307 at the appointed time Time-out；

Beyond maximum uplink timing difference, wherein, when maximum uplink timing difference is network configuration synchronization DC, The difference of the sub-frame boundary of uplink between MCG and SCG.

In make-before-break scheme, when wireless connection problem (including handoff failure, Radio Link occurs Failure, the change of secondary cell group fail, beyond maximum uplink timing difference) when, radio link failure and data can be produced The problem of interruption.

In view of the above-mentioned problems, effective solution is not suggested that in correlation technique.
