Background technology
At (the 3rd Generation Partnership Project of 3G (Third Generation) Moblie alliance, universal mobile telecommunications system (Universal MobileTelecommunication System 3GPP) formulating, UMT S) in, mobile management roughly can comprise community Xuan Ze ∕ gravity treatment (Cell Selection ∕ Reselection), handing-over (Handover) and relevant measurement thereof.Handing-over refers to that the program that the administrative power of subscriber equipment is converted to a target BS (Target Cell) from existing base station (ServingCell), all cell mobile communication systemses are all to utilize the idea of handing-over to realize the object of mobile communication.Handing-over mainly can be divided into two kinds of hard handing-over (Hard Handover) and soft handing-over (Soft Handover).All non-code division multiple accesss (Code Division Multiple Access, CDMA) system is all used hard handing-over, for example time division multiple access (Time Division Multiple Access, TDMA) system is after doing and can first current connection being cut off while joining, set up new connection with new base station again, the required hardware structure of the hard handing-over of this first company of having no progeny (Break-before-Make) is comparatively simple, but cutting off rate (Call Drop) is higher.Code division multiple access system is because adopt the framework of orthogonal coding and Rake receiver (Rake Receiver), therefore can be before cutting off current connection first and target BS set up new connection, this soft handing-over that first connects afterwards break (Make-before-Break) can reduce the cutting off rate while handing-over, but hardware structure or algorithm are comparatively complicated.
Three kinds of different set can be divided near base station subscriber equipment: active set (ActiveSet), Candidate Set (Candidate Set) and monitoring collection (Monitored Set).The base station being included in active set can form and be connected with mobile device in the time of soft handover.Be included in base station in Candidate Set in the time of soft handover not and mobile device connect, but its signal strength signal intensity has exceeded the lower limit that becomes active set.The signal strength signal intensity that is included in the base station in monitoring collection does not exceed the minimum lower limit of active set.Subscriber equipment can remove to measure the signal of all base stations in communication range at set intervals, then switches according to this.Soft handover has following three kinds of possible patterns: the replacement that removes (RadioLink Removal) and active set that adds (Radio Link Addition), active set (Radio Link Replacement) of active set, deciding base station by subscriber equipment is to belong to active set or monitoring collection.Subscriber equipment can determine whether active set to be put into in the base station not connecting according to corresponding trigger condition (Triggering Condition), or from active set, removes the base station in connection.
Network terminal utilizes Broadcast Control Channel (Broadcast Control Channel, BCCH) that measurement criterion is sent to subscriber equipment, for handing-over management, radio bearer control (RadioBearer Control, RBC) and location.The parameter value that subscriber equipment can provide according to network terminal judges whether all base station signals at active set and monitoring collection meet central trigger condition, and in the time meeting certain trigger condition, can report radio network controller (BroadcastNetwork Controller, BNC), then by radio network controller determine whether to take corresponding switching to move.
When subscriber equipment detects the base station that signal is stronger, can send according to this corresponding measurement report event (measurement report event) and upgrade active set.But network terminal sometimes may for example, because some reasons (transmitting failure or storage area deficiency) and response measurement reporting event not.If subscriber equipment continues for some time and sends identical measurement report event always, and network terminal is not slowly sent the notice of upgrading active set, subscriber equipment cannot be handover to the base station that signal is stronger, become too poor and cause call drop because of script base station signal possibly afterwards, and user cannot learn call drop reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of not method of response measurement reporting event of network terminal of analyzing, and learns that with Let user call drop reason is to cause and join unsuccessfully because network terminal cannot respond particular measurement reporting event.
