Description

A kind of service cell updating method and device
Technical field
The application is related to communication technical field, more particularly to a kind of service cell updating method and device.
Background technology

For the information transfer suitable for small data quantity, chain of command (Control is introduced in 3GPP Release 13 Plane, CP) scheme and (User Plane, UP) scheme.In CP schemes, small data packets pass through Non-Access Stratum (Non-access Stratum, NAS) message transmission.And in side of eating dishes without rice or wine, then by wireless heterogeneous networks (Radio Resource Control, RRC) connection setup complete message, up direct-sending message (UL Information Transfer) and descending direct-sending message (DL Information Transfer) transmit these small data packets.In UP schemes, in order to save signaling consumption and network side Related processing load, introduce the mechanism that hang-up (suspend) RRC connections connect with recovery (resume) RRC.Hang up RRC During connection, UE and network side store UE some information, during RRC connections to be restored, can reuse previous information and be used for RRC Connection.When base station determines that hang-up is currently connected with UE RRC, meeting phase UE sends RRC connection release requests, wherein referring to comprising hang-up Show, and distribute one to UE and recover mark (Resume ID), recover relevant configuration to follow-up.UE receives RRC Connection Releases please After asking, idle (IDLE) state is entered.Although the RRC now between UE and base station is in suspended state, UE and base station are deposited Store up the configuration of UE Access Layer (Access Stratum, AS) layer.When UE needs to reenter RRC connected states, initiate RRC and connect Recovery request is connect, wherein carrying the Resume ID received before, the information stored before, and then recovery and UE are obtained for eNB RRC connections.
At present because the transmitted data amount of the UE in NB-IoT is small, sending data time, short and most of UE is probably quiet Only, therefore 3GPP Release 13 do not support the mobility of UE connected states at present, as the UE in connected state because movement is led When causing current signal quality variation, only after UE judges Radio Link Failure (Radio Link Failure, RLF) occurs, Ability triggering following behavior.For example under CP schemes, RLF is directly informed NAS layers by UE, is further processed by NAS layers, in UP Under scheme, UE initiates RRC connection reconstruction processes, recovers the connection with network side.

The message is transferred to UE by source base station by RRC connections reallocation message, and UE performs the associative operation of switching.
But the measurement mechanism of above-mentioned switching flow is more complicated, multiple measurement results report can also cause additionally to UE Power consumption.

The embodiment of the present application is described in further detail with reference to Figure of description.
Embodiment one
As shown in Fig. 2 the service cell updating method flow diagram provided for the embodiment of the present application one, comprises the following steps：
S201：Connected state user equipment (User Equipment, UE) selection target cell.
Here, connected state UE can continue to use the cell reselection principle (mode one) under existing Idle state, can also be by servicing Cell is its special configuration Target cell selection parameter (mode two).
Mode one：Connected state UE is based on cell reselection rules and cell reselection parameters, selection target cell.
Cell reselection parameters that here, UE can be broadcasted with reception system (for example system information block SIB3 broadcasts public one A little cell reselection informations, SIB4 broadcast co-frequency cell reselection information, alien-frequency district reselection information etc. are broadcasted in SIB5)；Or connect Receive the cell reselection parameters that current service cell is sent by radio resource control RRC dedicated signaling.
Preferably, cell reselection parameters can include：For the offset for the difficulty for increasing service cell updating；And/or For the thresholding for the difficulty for increasing access low priority cell.
In actually implementing, in order to which UE still can connect in former serving cell when ensureing to occur the service cell updating of connected state Data are received and send, the demand on signal quality of UE original serving cells when service cell updating occurs for connected state during Idle state than entering It is high during row cell reselection, thus base station can in system information block (System Information Block, SIB) message volume One offset Qconnecteddelta of outer broadcast, the R values for serving cell in cell reselection R criterions are calculated, now serviced The R values of cell are changed into Rs=Qmeas,s+QHyst-Qoffsettemp+ Qconnecteddelta, wherein, Qmeas,sFor serving cell Reference Signal Received Quality (Reference Signal Receiving Power, RSRP), QHystIt is slow for serving cell gravity treatment Stagnant value, QoffsettempBias between serving cell and adjacent cell.In addition, in order to ensure gravity treatment to low priority cell UE remains to send data in former serving cell when (native region priority order can be system broadcasts), can be used for extra broadcast Thresh of the connected state UE gravity treatments to low priority cellServing,LowPAnd ThreshServing, LowQ(it is more than taking under Idle state Value), wherein serving cell meets cell selection quality value Squal ＜ ThreshServing,LowP, serving cell selection reception level Value Srxlev ＜ ThreshServing, LowQWhen re eligible to the condition that meets low priority cell.
In addition, in existing cell reselection rules, it is also necessary to which reading the cell that the parameter in SIB1 confirms to treat gravity treatment is No be in forbids access state, if in access state is forbidden, does not consider gravity treatment to the cell.And in application scheme In, connected state UE, although being to try to reuse existing cell reselection rules, need not be read when carrying out Target cell selection Whether the cell that system information confirms currently to select gives tacit consent to the current cell for the treatment of selection to allow connect in access state is forbidden The state entered.
Mode two：UE receives the Target cell that serving cell is sent by radio resource control RRC dedicated signaling and selects ginseng Number；Based on the Target cell selection parameter selection target cell.
Here, the Target cell selection parameter of connected state is directly sent to UE by serving cell by RRC dedicated signalings.Mesh Marking cell selection parameters includes measurement object information, measurement report configuration information and measures the one or more opened in thresholding.
For example { measurement object mark 1, measurement object is frequency 1 for configuration；Measurement report mark 1, measurement report is configured to A3 events and A3 events relevant parameter }, measurement object mark 2, measurement object is frequency 2；Measurement report mark 1, measurement report It is configured to A3 events and A3 events relevant parameter }.The definition of specific event and relevant parameter measure thing referring to existing connected state The definition of part, I will not elaborate.
S202：Target cells of the UE based on selection, initiate service cell updating.
In specific implementation, UE can send cell update request, Zhi Houyou after selection target cell to serving cell Serving cell initiates handover request to Target cell.Service cell updating actively can also be initiated to Target cell from UE.Specifically It is as follows：
Mode one：UE sends cell update request to serving cell, and serving cell asks to select to UE based on the cell update The Target cell selected initiates handover request.
Here, cell update request includes Physical Cell Identifier (the Physical Cell of Target cell Identifier, PCI) and frequency point information.In addition to this it is possible to comprising it is after being sorted according to signal quality, except Target cell The Physical Cell Identifier PCI and frequency of outer other adjacent cells for meeting UE access conditions, other adjacent cells here can be Meet the adjacent cell having access to of cell selection rule, or meet UE access bars according to what Target cell selection parameter determined The adjacent cell of part, for aiding in current service cell side to determine the reconstruction cell list in handover request, to be selected to UE Target cell initiate service cell updating failure after, UE can successfully be carried out in other adjacent cells in the reconstruction cell list RRC connection reconstructions；Or serving cell directly according to the UE Target cells selected and can be rebuild other in cell list Adjacent cell, the current loading condition notified with reference to each adjacent cell and priority orders etc., determine to initiate serving cell more for UE New adjacent cell.
After serving cell receives UE cell update request, the Target cell to UE selections is asked based on the cell update Handover request is initiated, service cell updating process here can be similar to existing cell switching flow.
Aforesaid way one is applied to CP and UP schemes.
Mode two：Under CP schemes, UE directly can initiate radio resource control RRC connection to Target cell and establish request The request of (contextual information of RRC connections before not considering) or RRC connection reconstructions (believe before consideration by the context of RRC connections Breath).
In addition, before initiating RRC connections to Target cell and establishing request or the request of RRC connection reconstructions, UE can be to clothes Cell of being engaged in sends cell update request, and serving cell asks the contextual information of the UE being transferred to mesh based on the cell update Mark cell.So, Target cell may be referred to UE contextual information and UE establishes RRC and is connected.
Mode three：Under UP schemes, UE sends cell update request to serving cell first, and serving cell is receiving UE Cell update request after, UE contextual information is transferred to the Target cell that indicates in cell update request.UE is being sent out After sending cell update to ask, then initiate RRC connection reconstructions to Target cell and ask.
In specific implementation, in order to avoid UE continually initiates service cell updating, UE can be set to initiate serving cell The time interval of renewal is not less than given threshold, for example 2s, the given threshold can provide in the protocol, can also be by network side Notice.
In order to mitigate cell load, NB-IoT supports multi-carrier operation.Under multi-carrier operation, carrier wave be divided into anchor and Non-anchor, i.e. main carrier and secondary carrier.In aforesaid way one, mode two and mode three, non-anchor weight is supported Choosing (such as the non-anchor being currently resident under some anchor, then Target cell is other anchor or other anchor Under non-anchor；Some anchor is currently resident in for another example, then Target cell can be other anchor or other Non-anchor under anchor).
, can be by the signal measurement result of the anchor belonging to non-anchor during Target cell selection is carried out The signal measurement result of (signal intensity or signal quality) as the non-anchor.In selection target cell, UE can be with Anchor or non-anchor under it are randomly choosed as Target cell；Or by the non-under anchor and the anchor In anchor, UE receives the carrier wave of paging as Target cell.
Connected state UE oneself selection target cells in above-described embodiment, and the Target cell based on selection, it is small to initiate service Area updates.Reported due to taking multiple measurements result without UE, therefore can reduce UE's while service continuity is kept Power consumption.
The thought of the embodiment of the present application is described further below by several specific embodiments.
Embodiment two
Under the embodiment, UE uses cell reselection relevant information selection target cell.
As shown in figure 3, the service cell updating method flow diagram provided for the embodiment of the present application two, comprises the following steps：
S301：Connected state UE obtains the cell reselection parameters of Idle state.
Here, some public cells are broadcasted in current service cell by system broadcasts cell reselection parameters, such as SIB3 Reselection information, SIB4 broadcast co-frequency cell reselection information, alien-frequency district reselection information etc. are broadcasted in SIB5.UE is by reading system Information, obtain cell reselection parameters.Or cell reselection relevant information is sent out by dedicated signaling mode in current service cell Give connected state UE.
S302：Connected state UE is based on cell reselection rules and the cell reselection parameters obtained, selection target cell.
Here, UE is carried out according to the cell obtained again parameter in connected state according to the cell reselection rules of Idle state Target cell selection course.Such as according to the parameter broadcasted in SIB, when UE current service cells signal quality is more than system information When the common frequency measurement of broadcast opens thresholding and different-frequency measure unlatching thresholding, then without with frequency and different-frequency measure, otherwise opening same Frequency and/or different-frequency measure.After same frequency and/or different-frequency measure to be opened, according still further to cell reselection rules, judge whether to need gravity treatment To the cell of measurement, if necessary to gravity treatment to the cell, then the cell is selected as Target cell.
S303：UE sends cell update request to current service cell, wherein carrying the physical area mark of Target cell Know (Physical Cell Identifier, PCI) and frequency point information.
In addition, the adjacent cell signal quality that UE can also obtain according to measurement, by other symbols in addition to Target cell Close the Physical Cell Identifier PCI of the adjacent cell of cell reselection rules and frequency point information sorts that (for example descending is arranged according to signal quality Row) carry ask to be sent to current service cell in cell update afterwards, rebuild cell row for aiding in current service cell to determine Table.
S304：Serving cell is asked according to cell update, it is determined that the Target cell of switching, is initiated to the Target cell of determination Handover request.
In specific implementation, other information of adjacent cells that serving cell can report according to UE, it is determined that cell list is rebuild, And the handoff procedure of triggering following.Specifically, serving cell sends UE handover request to Target cell, and Target cell allows to connect Being returned after entering allows the response message of access, and UE is received and Target cell is updated into current service cell after response message, subsequently Operation is similar with existing switching flow.
Here, serving cell can transmit the one of cell reselection parameters to the service cell updating request that Target cell is sent A little information, matching somebody with somebody again for cell reselection parameters is carried out for Target cell, while Target cell is sent in UE response message Include the cell reselection parameters matched somebody with somebody again.
In specific implementation, after UE sends cell update request, if subsequently needing gravity treatment again according to cell reselection rules To other Target cells, then need just send cell update request again after setting time threshold value T is spaced, so as to avoid UE Frequently carry out cell update.T can be predefined, for example provide 2s in the protocol, or network side is by itself and cell Reselecting parameters send jointly to UE's.
Cell reselection principle selection target cells of the connected state UE based on connected state in above-described embodiment, and based on selection Target cell, initiate service cell updating.Reported due to taking multiple measurements result without UE, therefore service can kept to connect While continuous property, UE power consumption is reduced.
Embodiment three
Under the embodiment three, the Target cell choosing for the connected state that UE is sent using serving cell by RRC dedicated signalings Select parameter selection target cell.
