The present invention discloses a network-side rescue method for service abnormality in a third-generation communication network. The steps of the rescue method include: after the wireless network controller judges that the wireless link is abnormal, the node B stops the downlink power transmission, and the terminal goes in the downlink direction. If the wireless link fails, actively search for the cell and report the cell update message to the radio network controller; the radio network controller receives the cell update message, deletes the wireless link, establishes a new wireless link, and sends a cell update confirmation to the terminal The message enables the terminal to synchronize on the new wireless link, and sends physical channel reconfiguration, transport channel reconfiguration, and radio bearer reconfiguration completion messages to the network side. According to the feature that the terminal actively reports the cell update to the network side when the downlink is out of sync, the present invention saves the service drop when the wireless environment or the network is abnormal, so that the user does not need to re-initiate the call operation, and not only improves the system call drop rate index , and bring convenience to users.
Description
Technical field
The present invention relates to moving communicating field, particularly the third generation (3rd Generation, 3G) a kind of service exception rescue method in.
Background technology
At present, the communication technology constantly develops, data traffic requirement constantly enlarges, the user continues to increase, because wireless environment or network side take place unusual, there is larger interference as the adjacent area with putting again and again, terminal moves to weak overlay area and causes carrier/interface ratio relatively poor, there is rapid fading etc., can make network side detect uplink loss, Radio Link control (RLC) layer occurs unusual, the space interface signaling terminal does not have situations such as response, may cause the configuration of network side and terminal side data to take place inconsistent, can't carry out normal subsequent communications and interacting message, network side can initiatively be initiated link and be discharged request, and the RAB of indication core net releasing bearing finishes this calling procedure.The user need make a call again and operate and could carry out business procedure once more, has a strong impact on user's impression.
In addition, for system, because above-mentioned abnormal conditions take place, need to discharge RAB, system's cutting off rate=(the RAB number that RAB number/network side that the network side initiation discharges is successfully set up), by the definition of present system cutting off rate as can be known, discharge the RAB number and increase, can have a strong impact on system's cutting off rate index.
When uplink loss takes place after, the sign special uplink channel has occurred unusually, can't finish the normal communication process, have only by uplink common channel and could carry out alternately with terminal, under connected state, the terminal and the network side reciprocal process that are carried on the uplink common channel only have cell updating course a kind of, and the triggering cell reason for renewing is multiple, and what network side was controlled is " Radio Link Failure ".
Terminal need be checked descending synchronous regime in physical layer in each radio frames, synchronous regime is indicated to high level by physical layer " indication synchronously " or " step-out indication " primitive, when following three conditions were met simultaneously, terminal physical layer then reported " step-out indication " to high level.
1. terminal is in 160ms, and detected dedicated channel burst quality continues to be lower than a particular value;
2. terminal is in 160ms, and the signal quality that does not detect a special burst is higher than a particular value;
3. terminal does not receive any transport module that has correct CRC in 160ms.
When network side stops power emission on the down direction, the end side physical layer then can satisfy and reports the step-out indicated condition, reports " step-out indication " to high level.
Definition among the 3GPP TS 25.331, when terminal was in the CELL_DCH state, after the step-out indication of receiving N313 DPCH from physical layer continuously, terminal should start timer T313, if T313 is overtime, terminal is then thought Radio Link Failure on the down direction.Terminal detects and satisfies the radio link failure condition on the down direction, can initiatively carry out cell search process, and upgrade, after network side is received cell update message to the network side triggering cell, by the cell update acknowledgement message is that terminal is redistributed a cover resource, finishes business continuing.
Summary of the invention
When the purpose of this invention is to provide a kind of service exception, the network side rescue method, after network side detects abnormal conditions, be that terminal is redistributed a cover resource by network side rescue method of the present invention, make the user need not to make a call again and operate and still can carry out business procedure.A kind of service exception network side rescue method initiatively stops the descending power emission in the third generation communication network of the present invention after network side detects unusually, and the descending step-out reporting subdistrict of triggering terminal upgrades, and finishes business continuing, and the step of described method is as follows:
Radio network controller judges that Radio Link is unusual, and instructs node B stops the descending power emission;
Node B stops the descending power emission, terminal is consecutively detected the step-out indication and makes timer expiry, then judge Radio Link Failure on the down direction, terminal is initiatively carried out Cell searching and is used common signal channel to described radio network controller reporting subdistrict updating message;
Described radio network controller is received described cell update message, deletes described Radio Link, sets up new Radio Link, sends the cell update acknowledgement message to terminal;
Terminal is received the cell update acknowledgement message, carries out on new Radio Link synchronously, finishes message to network side transmission physical channel reprovision, transmission channel reprovision, radio bearer reprovision.
In the above-mentioned steps, radio network controller judges that described Radio Link unusual situation takes place including but not limited to following three kinds of situations:
When described radio network controller was received the up-link wireless link failure indication that Node B reports, it was unusual to judge that described Radio Link takes place;
Described radio network controller is overtime when not receiving terminal to report message, and it is unusual to judge that described Radio Link takes place;
When resetting, the RLC that issues to terminal indicate the maximum times that reaches setting, described radio network controller not to receive that yet terminal resets when responding, and judges that then described Radio Link is unusual.
In the above-mentioned steps, after described radio network controller judges that Radio Link is unusual, by send Radio Link activation command or Radio Link removal request to Node B at described Radio Link, instructs node B stops descending power emission, and is provided for the waiting timer of the cell update message that receiving terminal reports.In Radio Link activation command or the Radio Link removal request, Radio Link is designated described Radio Link sign, and the activation type in the activation command is deexcitation.Deexcitation can be adopted synchronous deexcitation and asynchronous deexcitation, and described synchronous deexcitation need be specified CFN.
Described waiting timer is overtime, and radio network controller is not received the cell update message of terminal to report yet, then discharges RAB.
Described cell update acknowledgement message comprises the relevant information of physical channel, transmission channel and radio bearer that network side reconfigures etc.
Compared with prior art, beneficial effect of the present invention is: the present invention according to terminal when the descending step-out initiatively to the characteristic of network side reporting subdistrict updating message, wireless environment or network are taken place when unusual, save professional call drop, thereby make the user need not the operation that makes a call again, not only improved system's cutting off rate index, and offered convenience for the user.
