Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of definite method and apparatus of cell reselection priority.
Background technology
One, RRC (Radio Resource Control, Radio Resource control) connection release message and cell selecting brief introduction.
Comprise redirection information and cell reselection priority information in the RRC connection release message.Redirection information is used for specifying a specific frequency to UE (User Equipment, subscriber equipment), after UE discharges the RRC connection, preferentially on this frequency, carries out cell selecting.And cell reselection priority information is used for after the UE indicating cell is selected, can carrying out the priority of the frequency of district reselecting.
Network sends dedicated signaling to UE and discharges connection; UE gets into RRC_IDLE (RRC_ idle pulley) state and resides in a certain sub-district through cell selecting (cell selection) from RRC_CONNECTED (RRC_ connection mode) state; UE should attempt residing in last sub-district (implicit expression of RRC_CONNECTED state; When being redirected), or E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, the UMTS Terrestrial radio access network of evolution of in the dedicated signaling of state exchange, indicating; UMTS:Universal Mobile Telecommunication System, UMTS) sub-district (explicit) in frequency or other RAT (Radio Access Technology, the wireless access technology) frequency through redirection information; When residing in a certain sub-district, UE during triggering cell gravity treatment flow process, should attempt gravity treatment to a proper cell (suitable cell).Fig. 1 is idle pulley (RRC_IDLE) cell selecting and gravity treatment implementing procedure sketch map, does not have proper cell (suitable cell) in the time of can selecting at UE, and the flow process shown in the dotted line of overstriking among Fig. 1 so is divided into three kinds of situation substantially:
If a) this UE gets into connection status from " normally resident " state (camped normally); When it gets back to idle condition so; If the frequency of in dedicated signaling, indicating (explicit or implicit expression) does not have proper cell (suitable cell) to select, UE should carry out the cell selecting flow process through the cell information (stored information) of storage and select a proper cell (suitable cell) resident; If can not obtain proper cell in the cell information of storage, get into cell initial search flow process (initial cell selection) so.
B) if this UE gets into connection status from " residing in any sub-district " state (camped on any cell); When it gets back to Idle state so; If the frequency of in dedicated signaling, indicating (explicit or implicit expression) does not have acceptable sub-district (acceptable cell) to select; UE should get into " any cell selecting " state (any cell selection); Continuation acceptable sub-district of search (acceptable cell) in all PLMN (Public Land MobileNetwork, public land mobile network) is carried out resident.
C) but can not choose proper cell (suitable cell) if triggered district reselecting at " normally resident " state (camped normally); Perhaps triggered district reselecting and but can not choose acceptable sub-district (acceptable cell) at " residing in any sub-district " state (camped onany cell); UE can get into " any cell selecting " state (any cell selection), and the acceptable sub-district of search (acceptable cell) is carried out resident in all PLMN that UE supports.
Two, based on the different frequency/different technique district gravity treatment brief introduction of priority.
Alien frequencies and different technique district gravity treatment are all judged based on priority and are carried out.UE is when carrying out reselection evaluation to certain different frequency/different technology; Need distinguish according to the relation (be higher than, equal, be lower than) of its priority and the resident frequency priority of current UE and treat, detail is seen 5.2.4.5 joint among 3GPP (the 3rd Generation Partnership Project) 36.304.
In addition, when UE judges whether that startup is measured certain different frequency/different technology, also to distinguish and treat according to the relation of its priority and the resident frequency of current UE:
A), be higher than the different frequency/different technology of the resident frequency of current UE, measure according to the requirement of 3GPP (3rdGeneraion Partnership Project) 36.133 agreements for priority;
B), be equal to or less than the different frequency/different technology of the resident frequency of current UE for priority, when the Serving cell quality is lower than certain thresholding (S
Nonintrasearch) time, just start corresponding measurement.
Three, the indicatory device brief introduction of priority.
Between different different technology, do not allow identical priority.And current agreement regulation UE can only provide by system information E-UTRAN frequency or different technological frequency and hereto frequency the assessment of just carrying out district reselecting under the situation of priority is arranged.
The frequency precedence information of district reselecting is from following two kinds of means:
A), common signaling (being system information): the precedence information of the resident frequency of current UE wherein is provided, the precedence information separately of other frequencies of E-UTRAN, and the precedence information separately of each frequency (section) of other RAT.This is called public precedence information.
B), dedicated signaling: in the RRC connection release message, carry the priority list of E-UTRAN different frequency/different technology frequency alternatively, and corresponding term of validity timer length.This is called special priority information.In dedicated signaling, also carried simultaneously dedicated priority timer effective time T320.
Four, public precedence information and special priority information concerns brief introduction.
Stipulate that in existing LTE (Long Term Evolution, Long Term Evolution) standard when UE did not receive dedicated signaling indication special priority information, the public priority that provides in the using system information was measured and district reselecting; After receiving special priority information; UE will no longer consider any public precedence information; Behind the term of validity timer expiry or (because other reasons) termination of special priority information; UE just can abandon special priority information, and restarts to carry out corresponding measurement and district reselecting based on public precedence information.
The deficiency of prior art is: under some scene; Dedicated cell gravity treatment priority and special-purpose timer are effective; And UE can not reside in the sub-district that these have dedicated cell gravity treatment priority; Resident sub-district was not the sub-district under (the explicit or implicit expression) frequency of indicating in the connection release message after for example the UE connection discharged; Sub-district under the frequency of cell reselection priority is provided in neither connection release message, and connection release message provides the cell reselection priority of other frequencies, this situation causes this UE before the dedicated priority timer expiry, can't carry out the measurement and the reuse adoption process of any different frequency/different technology.

Embodiment
Describe below in conjunction with the accompanying drawing specific embodiments of the invention.
The inventor notices in the invention process; Under some scene; Dedicated cell gravity treatment priority and special-purpose timer are effective; And UE can not reside in the sub-district that these have dedicated cell gravity treatment priority, and for example connect to discharge resident sub-district, back be not the sub-district under (the explicit or implicit expression) frequency of indicating in the connection release message to UE, and the sub-district under the frequency of cell reselection priority is provided in neither connection release message; And connection release message provides the cell reselection priority of other frequencies, and this situation causes this UE before the dedicated priority timer expiry, can't carry out the measurement and the reuse adoption process of any different frequency/different technology.
Fig. 2 provides available frequency point information sketch map after the frequency priority for dedicated signaling; P represents the priority under this frequency among the figure; The typical scene that then can't carry out technological measurement of any different frequency/different and reuse adoption process is as shown in Figure 2; The connection release message that UE receives has been indicated special priority information and the dedicated cell gravity treatment priority timer of f2, f3; The system information of the frequency f1 that the UE of dedicated signaling indication simultaneously is preferential resident provides the public precedence information of f1, f2, three frequencies of f3; But the condition of proper cell (suitable cell) all can not be satisfied in the sub-district among the f1; So the resident sub-district of arriving under the frequency f4 of UE, the sub-district under the frequency f4 possibly be the acceptable cells (acceptable cell) that perhaps obtains through " any cell selecting " state (any cell selection state) through the proper cell (suitable cell) that storage cell information (stored information) or initial cell select (initial cellselection) to obtain.
According to existing protocol; UE is after receiving connection release message, because frequency f1 does not satisfy resident condition, UE is resident to frequency f4; But UE only has the dedicated priority of f2, two frequencies of f3, and the current resident frequency f4 of UE has no cell reselection priority information.
Under another typical scene; Before dedicated cell gravity treatment priority timer expiry; If having triggered district reselecting at " normally resident " state (camped normally), UE but can not choose proper cell (suitable cell); Perhaps triggered district reselecting and but can not choose acceptable sub-district (acceptable cell) at " residing in any sub-district " state (camped on any cell); Can get into " any cell selecting " state (any cell selection), continue in all PLMN, to search for acceptable sub-district (acceptable cell) and carry out resident.The resident dedicated cell gravity treatment precedence information that can not guarantee to have current resident frequency behind the new sub-district of UE under these situation.
Description according to the front can be known; In case UE can't confirm the precedence information of current resident frequency; It also can't normally carry out the measurement and the reuse adoption process of other any different frequency/different technology so, and then influences follow-up resident and call setup flow process, thereby has worsened user experience.
Based on this, the present invention had proposed before dedicated cell gravity treatment priority timer expiry in implementing, and when UE resides in the frequency that does not have the configure dedicated cell reselection priority, confirmed that the cell reselection priority that UE uses solves this problem.
Fig. 3 is definite method implementing procedure sketch map of cell reselection priority, and is as shown in the figure, carrying out cell reselection priority when confirming, can comprise the steps:
In the enforcement, step 301 and the uninevitable execution sequential relationship of step 302, it all is the necessary condition of execution in step 303, need only satisfy getting final product.
Describe in the face of the execution mode of confirming the cell reselection priority that UE uses in the step 303 down.Consider the producing method that priority is possible, clearly decide the execution mode of the cell reselection priority that UE uses the priority that fixedly installs from frequency respectively below, the priority of from system information, obtaining and the priority from public precedence information.Obviously; Description by following execution mode can be found out; As long as can guarantee UE the cell reselection priority information of resident frequency is arranged on its resident frequency, guarantee that the execution mode that UE under any circumstance can proceed to the district reselecting of alien frequencies or different technology can realize the present invention.
One, confirms that UE uses preset fixedly dedicated cell gravity treatment priority at its resident frequency to this frequency.
In the enforcement; Before dedicated cell gravity treatment priority timer expiry; When UE resides in the frequency that does not have the configure dedicated cell reselection priority; This frequency uses fixing cell reselection priority information, to guarantee that UE can have the special priority information of resident frequency all the time, so that the carrying out of follow-up measurement and cell reselection process.
Fig. 4 is for using fixing dedicated cell gravity treatment precedence information sketch map, and P represents the priority under this frequency among the figure, and is then as shown in the figure, and when in connection release message, having indicated dedicated cell gravity treatment priority and timer to be example, practical implementation can be following:
The preferential resident frequency of the UE of connection release message indication is f1, and the public precedence information of some frequency f1, f2 is provided in this system information of subdistricts, has indicated the special priority information P of (at least one) frequency (for example f2 frequency) in the connection release message
F2 *UE does not have proper cell (suitablecell) can be resident the time at frequency f1; Selection resides in a certain sub-district under the frequency f3; The public precedence information of some frequency f2, f3 is provided in this system information of subdistricts, and then UE resides in that available dedicated priority is the priority P of f2 behind the frequency f3
F2 *The priority P of (from dedicated signaling), f3
f *(from fixed value) can proceed to alien frequencies or different technique district gravity treatment to guarantee this UE that resides in f3 before the dedicated priority timer expiry.
In the practical implementation, the fixedly dedicated cell gravity treatment precedence information of in UE, presetting can be set to the UE cell reselection priority scope greater than the explicit dispensing of all high-level signalings.
For example: the UE cell reselection priority scope of the explicit dispensing of all high-level signalings generally is made as 8 grades in the prior art; It is the 0-7 level; Preset fixed priority scope that is to say to refer to that this scope, both can be less than lowest priority 0 greater than 0-7 greater than the UE cell reselection priority scope of the explicit dispensing of all high-level signalings; Also can certainly in 0-7, select greater than limit priority 7.Adopt the purpose of this mode to be to make the cell reselection process of UE side more flexible.The reason that this mode can be implemented only needs UE to discern and get final product after being that this scope is set, and does not relate to network side because this reuse adoption process also only relates to UE, so need not network improved and just can realize UE is indicated more flexibly.
Two, confirm the cell reselection priority of this frequency that UE provides in its resident frequency using system information.
In the enforcement; Before dedicated cell gravity treatment priority timer expiry; When UE resides in the frequency that does not have the configure dedicated cell reselection priority; This frequency is used the cell reselection priority information of this frequency that provides in the current persistent district system information of UE, to guarantee that UE can have the special priority information of resident frequency all the time, so that the carrying out of follow-up measurement and cell reselection process.

The preferential resident frequency of the UE of connection release message indication is f1; The public precedence information of some frequency f1, f2, f3 is provided in this system information of subdistricts, has indicated the special priority information P of (at least one) frequency (for example f2 frequency) in the connection release message
F2 *UE does not have the proper cell (suitable cell) can be resident at frequency f1; Selection resides in a certain sub-district under the frequency f3; The public precedence information of some frequency f2, f3, f4 is provided in this system information of subdistricts, and then UE resides in that available dedicated priority is the priority P of f2 behind the frequency f3
F2 *The priority P of (from dedicated signaling), f3
F3(from the system information of UE persistent district) can proceed to alien frequencies or different technique district gravity treatment to guarantee this UE that resides in f3 before the dedicated priority timer expiry:
Three, confirm that UE when the cell reselection priority that its resident frequency uses, uses the public priority in the public precedence information all.
In the enforcement, public precedence information can be the public precedence information that is provided by system information.
When using public priority all, can further include:
Delete cell reselection priority and dedicated priority timer that all are provided by dedicated signaling.
In the enforcement; Before dedicated cell gravity treatment priority timer expiry, when UE resides in the frequency that does not have the configure dedicated cell reselection priority, delete all dedicated cell gravity treatment priority and timers; All use the public precedence information that provides by system information; To guarantee that UE can have the precedence information of resident frequency all the time, so that the carrying out of follow-up measurement and cell reselection process describes with instance below.
