Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of neighboring BS relationship processing method and system.
Background technology
Along with the raising to demand for services with the user that increases of cell mobile communication systems provider customer number, the scale of cellular network constantly enlarges, and the base station number is on the increase, and the cell mobile communication systems of various standards is constantly deepened co-operation each other.This makes that the neighboring BS relationship of sub-district administers and maintains in the cellular network becomes more and more loaded down with trivial details work.
Fig. 1 is existing UTRA (Universal Terrestrial Radio Access, the general land wireless access) system architecture schematic diagram, as shown in Figure 1, in the UTRA network, universal land radio access web (UTRAN, Universal Terrestrial Radio Access Network) comprises radio network controller (RNC, Radio Network Controller) and base station (NodeB) two kinds of basic network elements.The neighboring BS relationship of numerous minizones under the hundreds of NodeB, the needs that can optimize along with the network planning and the variation of wireless environment of living in and dynamically change.
In the UTRA network, the correct neighboring BS relationship in minizone is extremely important to network performance.Such as: realize the optimum switching of user terminal (UE), guarantee its service continuity, help network to realize load balancing, capacity allotment, the energy-conservation multipurpose that waits.Under pure manual adjacent area layout, the neighboring BS relationship that network side will configure in advance is notified to UE by system broadcast message or proprietary control messages, and UE further stores and utilize the sub-district neighboring BS relationship of receiving.But this neighboring BS relationship that configures in advance from network side may be out-of-date, can not really reflect real-time neighboring BS relationship, thereby may cause the mistake of UE to switch, even call drop, has reduced network performance.
In the UTRA system, 3GPP version 10 (Release10, REL-10) introduced a kind of Automatic Neighboring Relation function (ANRF, Automatic Neighbor Relation Functionality) of finishing mode (Best Effort to do) based on best endeavors.This scheme is based on minimum road test (MDT, Minimize Driving Test) technology, and idiographic flow may further comprise the steps as shown in Figure 2:
Step 200:UE resides in certain cell-of-origin under the RNC of source (Source cell), and this Source cell also can be described as current service cell (Serving cell).Source RNC selects certain suitable UE to carry out a certain class in the cell-of-origin or a few class ANR measures task.
Described ANR measurement task type is divided into basic 4 classes: measure and write down (Intra-frequency ANR logging), UTRA ANR frequency external pelivimetry and record (Intra-frequency ANR logging) in the UTRA ANR frequency, stride LTE ANR measurement and record (Inter-RAT LTE ANR logging), and stride GSM ANR and measure and write down (Inter-RAT GSM ANR logging).Interior and the frequently outer ANR of described frequency measures and record is referred to as intrasystem automatic adjacent section measurement and record (Intra-RAT ANR).
Step 201: source RNC carries out UE to selected before ANRF task in the cell-of-origin, transmission carries the Radio Resource control (RRC that ANR measures the control configuration parameter, Radio Resource Control) downstream message (DL Message with ANR Configurations), this RRC downstream message are specially record and measure configuration (Logging Measurement Configuration) message.
Wherein, the ANRF configuration parameter comprises: ANR measures in limited time parameter (ANR logging duration timer) and measures the parameter (ANR logging absolute threshold, ANR logging relative threshold) that the relevant cell signal of types is assessed with Intra-frequency ANR logging, Inter-frequency ANR logging, these 4 kinds basic ANR of Inter-RAT LTE ANR logging, Inter-RAT GSM ANR logging.UE preserves the ANRF configuration parameter that receives, and uses after waiting entering into proper A NR measurement state.
Step 202:UE has entered into certain and has been fit to the state that execution ANR measures through behind certain RRC Signalling exchange, and the ANRF configuration parameter of preserving before using is that the measurement of the adjacent unknown detected cells of a certain class or several classes is got ready.
In the protocol specification, the state that is fit to execution ANR measurement can be Idle state (Idle mode), Acceditation Area level paging attitude (URA_PCH), cell-level paging attitude (Cell_PCH) etc. at present.
Step 203: because possible mobility or the other reasons of UE itself, UE carries out measuring cell measurement task in the incoherent conventional Neighboring Cell List with ANR on the one hand, for the sub-district gravity treatment is prepared; On the other hand, UE is according to the ANRF configuration parameter of preserving before, carry out among the ANRF a certain class or a few class and measure task, and the unknown neighbor detected cells (comprise on physical layer information, the physical layer layer 2 information etc.) that will satisfy record (log) condition is recorded in the ANR record sheet (ANR Logging Table) of UE inside.
Record behavior in this step abbreviates ANR Logging or Logging as, is meant that UE executes the operation of recording after ANR measures.When UE satisfies the sub-district reselection conditions to the measurement result of certain the known neighbor cell in the conventional Neighboring Cell List, UE is still according in the Target cell of existing pattern gravity treatment in the conventional Neighboring Cell List, can't be subjected to the interference that ANR measures, that is to say, ANR measurement task is accompanied by the conventional sub-district gravity treatment behavior of UE, the cell reselection performance of UE is not subjected to the influence that ANR measures, and UE removes to carry out ANR as much as possible in the best endeavors mode and measures under the prerequisite that does not influence cell reselection performance.
Step 204: suppose that UE is selected and entered Target cell in certain Neighboring Cell List by gravity treatment, if had effective logging content in the ANR of the UE table, just in certain RRC upstream message of the Target RNC that sends to the Target cell place, indication has had and can report the ANR measurement result.
In this step, be used to indicate had and can report the RRC upstream message of ANR measurement result to be: RRC to connect to set up and finish (RRC Connection Setup Complete) message, cell update (Cell Update) message, URA and upgrade (URA Update) message, measurement report (Measurement Report) message etc.
Step 205: alternatively, UE has entered into certain and has been fit to carry out the state that ANR measurement result reports through behind certain RRC Signalling exchange, and carries out and report preparation.Described uploaded state specifically can be Cell_DCH, Cell_FACH state.
Step 206: the Target RNC at Target cell place requires UE to carry out the ANR measurement result and reports by certain RRC downstream message.This process can be called the automatic adjacent section measurement result and obtain (ANR Logging Results Retrieval), and described RRC downstream message can be UE information request (UE Information Request) message.
Step 207: according to the request of Target RNC, be kept at the ANR measurement result in the ANR table before UE reports by certain RRC upstream message, described RRC upstream message can be UE information response (UE Information Response) message.
Step 208: Target RNC is according to the ANR measurement result that obtains, safeguard relevant Neighboring Relation Table (Neighbor Relation Table, NRT).
Among Fig. 2, step 203 is crucial steps.For being in the PCH attitude and carrying out the UE that ANR measures, utilize the discontinuous reception idle period (UTRAN DRX Cycle DRX Off) in the discontinuous receiving cycle of the undefined UTRAN of PCH attitude in the cell-of-origin, adjacent unknown cell is carried out ANR measure, and measure at UE and to carry out record when the unknown neighbor detected cells satisfies certain record condition; For being in the Idle attitude and carrying out the UE that ANR measures, utilize the not discontinuous reception idle period (CN domain specific DRX cycle Off) in the specific discontinuous receiving cycle of same area of the undefined core net of Idle attitude in the cell-of-origin, adjacent unknown detected cells is carried out ANR measure, and UE measures and carries out record when unknown neighbor cell satisfies certain record condition.
In ANR measures, except to known neighbor cell measurement, UE also needs adjacent unknown detected cells physical signalling measured with cell quality and assesses, in case of necessity, also need the System information block (SIB) of the detected cells that satisfies record condition is read, so that obtain necessary layer 2 (L2) information (as cellular global identity etc.).As previously mentioned, after UE enters PCH or Idle attitude, no longer receive any control data except that paging (Paging), system message from RNC, therefore measuring relevant control configuration information with ANR was all sent and was preserved by UE by RNC before ANR measures startup, UE is when observing original cell reselection rules then, reasonably use these ANR configuration parameters to carry out ANR and measure, all ANR measure by the UE local scheduling.
For the ANRF of REL-10, mainly be the adjacent area relevant towards non-Home eNodeB type sub-district.Described Home eNodeB type sub-district refers to: opened by Home eNodeB (HNB) or enhancement mode Home eNodeB (HeNB) and register the class superminiature sub-district that the back is produced, this type of sub-district is mainly used in indoor covering, coverage is more much smaller than the grand Microcell of traditional sense, and minimum covering radius may have only about 10m.There are 3 kinds of mode of operations Home eNodeB type sub-district: open fully (Open), mix open (Hybrid), closed (Closed).Wherein, for closed, only belong to the community closed customer group of Home eNodeB type (Closed Subscriber Group, terminal CSG) could insert use; Open for mixing, the terminal that belongs to Home eNodeB type sub-district CSG can preferentially insert use, and the terminal that does not belong to Home eNodeB type sub-district CSG also can low level insert; For open fully, all terminals that possess the CSG ability can both insert use.Because the grand Microcell that has characteristic, deployment way and traditional sense of Home eNodeB type sub-district is different, so in order to simplify the complexity of relevant treatment, when the UE of the ANRF ability with REL-10 resides in the grand Microcell and does ANR measurement and record, do not consider the Home eNodeB type sub-district of any target; And in the UE of the ANRF ability with REL-10 resides in Home eNodeB type sub-district and be that ANR measures and during record, also do not consider the grand Microcell of any target or other adjacent Home eNodeB type sub-districts, its main cause is as follows:
1: the timeliness or the positional of the existence of Home eNodeB type sub-district have randomness, be that the Home eNodeB user can open registration whenever and wherever possible or close certain Home eNodeB type sub-district of cancellation, so relevant adjacent area, Home eNodeB type sub-district is a kind of unsettled information substantially;
2: the access difference of Home eNodeB type sub-district, if the mode of operation of certain Home eNodeB type sub-district is closed, all relative adjacent areas are just meaningful for the validated user that has the pairing CSG sign in described Home eNodeB type sub-district (id), do not have the inactive users of described CSG id then can not use this relevant adjacent area;
3: along with being extensive use of and deeply deployment of Home eNodeB type sub-district, Home eNodeB type number of cells may be numerous, if therefore ANRF is contained Home eNodeB type sub-district, bring the signaling storm of a lot of neighboring BS relationship probably.
As seen, existing ANR technology can not be measured or record the relevant any neighboring BS relationship of home base station cells.

Embodiment
In fact, the neighboring BS relationship that Home eNodeB type sub-district is relevant has certain effect and gain for network or UE, so network need learn valuable and the neighboring BS relationship about Home eNodeB type sub-district meaning, thereby is the travelling performance service of UE.
In actual applications, can continue to use among the REL-10 ANRF from being configured to the basic mode method of operation, be that UE receives relevant ANR parameter in proprietary attitude by Logging Measurement Configuration message, UE transfers to Idle, URA_PCH or Cell_PCH state then, when carrying out cell re-selection procedure, the ANR that is configured type measures and record.
ANR configuration related cells in Logging Measurement Configuration message is as shown in table 1.In the table 1, the sub-cell of the subordinate of standard indication UE strides the ANR log (Inter-RAT ANR for E-UTRA Indicator) of LTE sub-district to automatic adjacent section surveying record configuration information (Logged ANR Configuration Info), ANR log (Inter-RAT ANR for GSM Indicator) logical level that indication UE strides the GSM sub-district is identical; In addition, also increased two switch parameters of whether containing Home eNodeB type sub-district about ANRF: allowing UE is that target is carried out ANR measurement (H (e) NB ANR as target cell allowed), the ANR that is correlated with when allowing UE to reside in the Home eNodeB type sub-district measures (H (e) NB ANR as serving cell allowed) to Home eNodeB type sub-district.
Table 1
When UE resides in macrocell or Home eNodeB type sub-district and has been configured ANR when measuring, if Parameter H (e) NB ANR as target cell is allowed=TRUE, then UE can will satisfy the target Home eNodeB type sub-district of ANR log condition, notes with the form of the Target cell of current relatively resident service sub-district; Otherwise,,, note with the form of the Target cell of current relatively resident service sub-district only to satisfying the non-target Home eNodeB type sub-district of ANR log condition according to the standard of REL-10.
When UE resides in Home eNodeB type sub-district and be configured the ANR measurement, if Parameter H (e) NB ANR as serving cell is allowed=TRUE, then UE can continue ANR measurement behavior, to satisfy the target macro sub-district or the Home eNodeB type sub-district of ANR log condition, note with the form of the Target cell of current relatively resident service sub-district; Otherwise according to the standard of REL-10, the ANR that suspends UE measures behavior.
By two switch parameters shown in the table 1, network can more easily be controlled the sphere of action of ANRF in the process of the proprietary attitude ANR configuration of UE.If needs are arranged, above-mentioned two switch parameters also can transmit by other the RRC downstream message that contains ANR measurement control configuration parameter, such as passing through System Information or Paging Type I etc., UE can be configured or upgrade the value of described two switch parameters in non-proprietary attitude like this, adjusts the sphere of action of ANRF more neatly.
In order effectively to control ANR record at Home eNodeB type sub-district, Home eNodeB type sub-district can send switch parameter as shown in table 2 by RRC downstream messages such as System Information or Paging Type I: when Home eNodeB type sub-district is in the sealing mode of operation, permission is carried out ANR record (Allowed to be ANR logged in closed mode) by UE, when Home eNodeB type sub-district is in blend modes of operation, permission is carried out ANR record (Allowed to be ANR logged in Hybrid mode) by UE, when Home eNodeB type sub-district is in the open working pattern, allow to be carried out ANR record (Allowed to be ANR logged in open mode) by UE.
Table 2
As shown in Table 2, when certain Home eNodeB type cell system broadcast parameter Allowed to be ANR logged in closed mode=TRUE, when representing that this family base station type sub-district is in the sealing mode of operation, allow to be carried out the ANR record by UE.
When certain Home eNodeB type cell system broadcast parameter Allowed to be ANR logged in Hybrid mode=TRUE, when representing that this family base station type sub-district is in blend modes of operation, allow to be carried out the ANR record by UE.
When certain Home eNodeB type cell system broadcast parameter Allowed to be ANR logged in Open mode=TRUE, when representing that this family base station type sub-district is in the open working pattern, allow to be carried out the ANR record by UE.
By three switch parameters shown in the table 2, Home eNodeB type sub-district can inform whether UE enters neighboring BS relationship with this family base station type sub-district record valuable, meaningful according to the actual conditions of self after opening registration.Such as: the Home eNodeB type sub-district that has only prepares to open very short a period of time, and its relevant adjacent area exists very of short duration, and is not suitable for being noted by ANR, thereby switch parameter is not involved.In addition, network is from the practical application meaning or in order to prevent that too much Home eNodeB type sub-district from taking the log clauses and subclauses upper limit (as 4) of UE very soon, then can only comprise the switch parameter that some are in the Home eNodeB type sub-district of open working pattern, and not comprise the switch parameter of the Home eNodeB type sub-district of sealing, blend modes of operation.
If needs are arranged, 3 switch parameters in the table 2 can have multiple variation in form, perhaps in order to simplify, are merged into a common switch parameter, promptly no longer distinguish the ANR processing difference that mode of operation is brought.
Below, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
