Description
Technical field
The present invention relates to the switching abnormality processing in the distributed cellular wireless telecommunication system, particularly, relate to a kind of method for processing switch exception and system.
Background technology
Fig. 1 shows the schematic diagram of distributed cellular wireless telecommunication system.As shown in Figure 1, the distributed cellular wireless telecommunication system mainly is made up of terminal (perhaps being called travelling carriage), base station (BaseStation abbreviates BS as) and core net (Core Network abbreviates CN as).
Can carry out as required between the base station that logic connects or physical connection, the network that the base station is formed is called wireless access network (Radio Access Network abbreviates RAN as), is responsible for Access Layer affairs (for example, the management of Radio Resource etc.); On/descending Radio Resource is responsible for scheduling according to the mode of shared channel by the base station.Each base station can be connected with one or more core net node.Core net is responsible for Non-Access Stratum affairs (for example, mobile management etc.).Terminal is meant the equipment that can carry out communication with network, for example, and mobile phone, personal digital assistant or notebook computer etc.Each terminal can only be connected to one of them base station in the network on up direction.
Switching is one of characteristics of cellular mobile network, is the important step that guarantees service quality.The so-called switching is meant when terminal shifts out former Serving cell and will enter another Serving cell, replaced the process of the link between source base station and the terminal by the link between new base station and the terminal.Can guarantee wireless continuity in the sub-district and during the conversion of minizone by switching.
Fig. 2 shows the base station switching flow of present employing.As shown in Figure 2, specifically can comprise following processing (201-212):
201: terminal sends measurement report to source base station;
202: judge under the situation of needs switching the selected target BS that switches of source base station according to measurement report and switching control strategy at source base station;
203: source base station sends handoff request message to target BS, and carries necessary communication contextual information in handoff request message;
204: because the possibility handoff failure, in order to reduce subscriber equipment (UserEquipment behind the handoff failure, UE) rebuild the required time of link and between the network, source base station can also send handoff request message some candidate BS to other, and carries necessary communication contextual information in handoff request message;
205: after candidate BS receives handoff request message, do not need distribute to switch resource needed, only preserve the contextual information of terminal, so that use when recovering behind the Radio Link Failure;
206: target BS is the terminal distribution Radio Resource judging under the situation that allows to switch;
207: target BS sends switching request acknowledgement message to source base station, wherein, comprises in the switching request acknowledgement message that target BS is the Radio Resource of terminal distribution;
208: source base station sends switching command to terminal, comprises in this switching command that target BS is the Radio Resource of terminal distribution;
209: terminal is carried out at target BS and is switched;
210: terminal sends switching to target BS and inserts message on the target BS assigned radio resource;
211: target BS sends to terminal and switches access confirmation message;
212: terminal sends handoff completion message to target BS, and switching flow finishes.
Under the situation of handoff failure, for example, owing to temporary transient wireless quality reason terminal can't obtain with target BS synchronously, step 210 to 212 can't be carried out.And if terminal is not got back to source base station behind the handoff failure, then source base station can't know also whether switching is successful, and therefore, target BS also can't be judged the context that when should discharge this terminal.
Situation for above-mentioned handoff failure, regulation adopts the processing procedure similar to Radio Link Failure in long evolving system (Long TermEvolution abbreviates LTE as), promptly, fail if switch, then can use the processing procedure of Radio Link Failure, terminal will be selected a sub-district, may be original resident sub-district, it also may be the Target cell that switches, also may be other sub-districts, attempt by wireless connections recovery process re-accessing network, thereby avoid call drop.
Fig. 3 shows the processing procedure of Radio Link Failure, as shown in Figure 3, under the situation of Radio Link Failure, comprises following processing (301-305):
301: terminal keeps being connected with the base station, is in normal condition;
302: physical layer continues to detect the state of Radio Link, if found then to report high-rise key-course unusually, like this, base station and terminal can find that all Radio Link is unusual;
303: after high-rise key-course found that link is unusual, base station and terminal started timer T1 respectively, if physical layer has detected wireless link recovery normally before T1 is overtime, then thought and interrupted base station and not being connected of terminal, and it is normal that communication keeps;
304:, think then Radio Link Failure has taken place that base station and terminal start timer T2 respectively if still do not detect wireless link recovery in the overtime back of T1 physical layer; Before T2 was overtime, terminal can not be communicated by letter with original resident base station maintenance as original with having no effect, just can reconnect to wireless access network but need to carry out wireless connections recovery process.Wireless connections recovery process allows terminal to reselect a sub-district and is linked into network, and not necessarily is linked into original resident base station;
305: if the overtime back of T2 terminal does not still have successfully to recover and being connected of Access Network, think that then original being connected fully of terminal and Access Network interrupt, call drop has promptly taken place, terminal can be according to service needed re-accessing network once more.
In the said process 302 and 303 is called the phase I, and the feature in this stage is that terminal can be recovered to be connected with original resident base station with having no effect.304 are called second stage, and the feature in this stage is the wireless connections recovery process re-accessing network that terminal can be by protocol definition, keep original professional unaffected.Before this two stages, think that terminal still is in connection status, promptly still there is the context of this terminal in Access Network, can recover professional.After these two stages finish, if do not have all the time can re-accessing network for terminal, then Access Network will discharge the context of terminal, and terminal will enter idle condition.
In above-mentioned second stage, the processing of the wireless connections recovery process that terminal is carried out is specially:
At first, terminal is selected a proper cell, initiates random access procedure again;
Afterwards, if the random access procedure success, terminal sends wireless connections and recovers message on the Radio Resource of this cell allocation;
Next, if it is original resident sub-district that terminal is attempted the sub-district of wireless connections recovery, other sub-districts of the base station of perhaps original persistent district, or received sub-district in the base station of the handoff request message that original persistent district sends, then there is the context record of this terminal in these sub-districts, can identify this terminal; These sub-districts are given and will be sent wireless connections recovery acknowledge message to terminal, rebulid Radio Link, and return to the connection of core net according to the terminal contextual information;
If it is not certain sub-district above-mentioned that terminal is attempted the sub-district of wireless connections recovery, that is to say that there is not the context record of this terminal in this sub-district, then this terminal can't be discerned in this sub-district, will send wireless connection recovery refuse information to terminal.So terminal must be returned idle condition, be linked into network then again, can not recover original connection.
For the terminal of cell edge, if in handoff procedure, switch failure, then may be terminal handoff failure after successfully receiving switching command, also may be before the switching command that receives former persistent district transmission, Radio Link Failure to have taken place.Under above-mentioned two kinds of situations, no matter be handoff failure or Radio Link Failure, terminal all might be chosen the Target cell of determining in the step 202 and carry out above-mentioned wireless link recovery process.In fact, this moment, Target cell can not be determined terminal because which kind of reason is carried out the wireless link recovery process, that is, can't determine because handoff failure still is that Radio Link Failure causes; And, in step 206, Target cell may be for terminal distribution be different from the Radio Resource of cell-of-origin, so Target cell can't be judged whether terminal has received and is the new argument of this terminal configuration.The problems referred to above that exist will be brought inconvenience for follow-up wireless link recovery process, at present the method that also at the problems referred to above the wireless link recovery process is not optimized.
