Description
Technical field
The present invention relates to wireless communication field, in particular to a kind of information interacting method that is used for wireless access network information management coupling connection.
Background technology
RIM (RAN Information Management, be Radio Access NetworkInformation Management, wireless access network information management) is used to support GERAN/UTRAN (GSM/EDGE Radio Access Network, GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network, whole world terrestrial radio Access Network) carries out information interaction by core net between the peer application entity, comprise BSS (Base Station System, base station system) between, BSS and RNS (Radio NetworkSubsystem, RNS) information interaction between and between the RNS, interactive information is carried by Container (container), core net transparent transmission information of container.
Because therefore the RIM interaction flow unanimity between systems such as RNS/BSS only describes with RIM flow process between the BSS.Wherein, the BSS that need obtain information is called controllingBSS (master control BSS), provides the BSS of information to be called serving BSS (serving BS broadcasts S); RIM Association (RIM coupling connection) characterizes certain application (for example outside NACC that needs interactive information in the RIM flow process between the BSS, be Network Assisted Cell Change, a connection of setting up the sub-district gravity treatment of network support), this connection is made up of the tlv triple that master control BSS sub-district, serving BS broadcasts S sub-district and RIM application type constitute.
State between the RIM coupling connection that master control BSS and service BSS set up comes mark by the state variable MULTIPLE_REPORTING_ONGOING at RIM coupling connection two ends.For the RIM coupling connection of Multiple Report type, after the single information interaction finished, the state between the RIM coupling connection that master control BSS and service BSS set up was in activated state, and MULTIPLE_REPORTING_ONGOING is changed to TRUE.
RIM between BSS can realize the information interaction between RIM coupling connection and RIM application type alternately, and the RIM between BSS mainly comprises following flow process alternately:
(1) wireless access network information request (RAN Information Request) flow process: initiate when needs obtain information or Stop message transmission by master control BSS, be used to obtain the message transmission between application message or termination RIM coupling connection;
(2) wireless access network information sends (RAN Information Send) flow process: RIM coupling connection is set up the transmission of two ends, back application message;
(3) wireless access network information application error (RAN Information ApplicationError) flow process: send to serving BS broadcasts S during wrong application message in the container in receiving the RIM flow process by master control BSS and wrong application message to occur;
(4) wireless access network information errors (RAN Information Error) flow process: send to the information of makeing mistakes in the opposite end between RIM coupling connection during the messaging protocol mistake.
A kind of information interacting method of RIM coupling connection is provided in the correlation technique, in this method when master control BSS need be when serving BS broadcasts S obtains application message by the RIM flow process, application type triggers RAN-INFORMATION-REQUEST/Multiple Report message request, serving BS broadcasts S sends to application message master control BSS by RAN-INFORMATION/Initial Multiple Report in container, state between the RIM coupling connection of master control BSS and service BSS foundation is in state of activation afterwards, and this state of activation is that TRUE comes mark by the state variable MULTIPLE_REPORTING_ONGOING at RIM coupling connection two ends.In subsequent process, the application message that the RIM application type is obtained is joined by the RIM coupling of having set up that is in state of activation by the application type of serving BS broadcasts S to be safeguarded.If serving BS broadcasts S application type has information updating, then serving BS broadcasts S initiates RAN Information Send flow process the application message of upgrading is issued master control BSS application type to finish information interaction; If serving BS broadcasts S application type does not have information updating, then RIM coupling connection two ends do not have information interaction, so change in no abnormal situation under the situation of RIM coupling connection two ends state, RIM coupling connection two ends will remain the state of activation that MULTIPLE_REPORTING_ONGOING is TRUE.
Yet, may exist following abnormal conditions to change the RIM coupling and join the state of a certain end, thereby make that the state at RIM coupling connection two ends is no longer consistent:
(1) a certain end (master control BSS or serving BS broadcasts S) resets or other problems causes the one-sided RIM flow process of this end to discharge because the RIM coupling joins;
(2) owing to transmit or abnormality of core network, the RIM coupling joins the RIM information drop-out of a certain end (master control BSS or serving BS broadcasts S), and causes the one-sided RIM flow process of this end to discharge;
(3) it is inconsistent that other reasons causes the state at RIM coupling connection two ends.
In realizing process of the present invention, the inventor finds that the information interacting method of RIM coupling connection in the correlation technique is when abnormal conditions cause RIM coupling connection two ends no longer to be all activated state, information interaction between two ends is forced to interrupt, normal end is owing to can't learn the abnormal state of its opposite end, and still can as the RIM coupling joins just often, attempt sending or reception RIM message, cause the failure of RIM flow process and be difficult to recover normal, serious forgiveness is lower.
