Description
Technical field
The present invention relates to the communications field, and especially, relate to a kind of implementation method and device of cell reselection.
Background technology
In cell mobile communication systems, switching and cell reselection are wherein very important parts.The process of the switching of following Jiang Dui community and cell reselection is described.
Particularly, usually, as subscriber equipment (User Equipment, referred to as UE, also can be described as user terminal) when leaving the Yi Ge community and entering the another one community, the signal of the community, original place that this terminal is received will be more and more a little less than, and the received cell signal entered of this terminal will be more and more stronger.In order to keep terminal to receive the quality of signal, need this terminal is transformed into to the stronger cell base station of signal newly entered by the base station of community, original place, terminal for connected state, conversion between this base station just can be called switching, and for the terminal of Idle state, the change of terminal persistent district can complete by cell reselection process, need to be detected Target cell, carries out cell reselection in satisfactory community.
At the third generation (3rd Generation, referred to as 3G) in mobile communcations system, terminal can be measured the signal quality of different districts, and the signal quality that measures and the signal quality thresholding of persistent district are compared, if the signal quality measured arrives reselection criterion within a certain period of time continuously, terminal will gravity treatment reach the community of reselection criterion to this signal quality.
Particularly, terminal is carried out cell reselection and referred to: terminal need to be measured signal level or the signal quality of this community and neighbor cell, then this cell measurement value is mapped as to cell reselection assessed value Rs, and the measured value of tested neighbor cell is mapped as to Rn.Afterwards, put Rs and all Rn values together sequence relatively, what make number one is exactly the community of radio signal quality optimum, if now optimum subdistrict is not the resident current area of terminal, terminal is by gravity treatment Dao Gai community.The Rs here and the computational methods of Rn can determine according to agreement, and the relevant parameter related in computational process is issued by the broadcast channel of persistent district.
The method of above-mentioned cell reselection is at 3G (Third Generation) Moblie Long Term Evolution (Long TermEvolution, referred to as LTE) obtained application in co-frequency cell reuse adoption process in " universal land radio access web of evolution (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN) " system of system.In this reuse adoption process, Rs=Q
meas, s+ Qhysts Rn=Q
meas, n-Qoffset, wherein, s means persistent district, n means neighbor cell, Q
meas, smean persistent district measurement level, Q
meas, nbe the measurement level of neighbor cell, Qhysts means the sluggishness of Serving cell, and Qoffset is the level deviation value of adjacent cell, and terminal can be sorted all R values, and what make number one is current best cell, and terminal can gravity treatment arrive this best cell.In this reuse adoption process, the gravity treatment complexity of adjacent cell, except the wireless quality that depends on community, also depends on the value size of Qoffset, so this reselecting method of the sequence by R can be called the residence reselecting based on skew.Because this residence reselecting based on skew need to be measured in all frequencies and the neighbor cell frequently, therefore can cause the end cell depletion rate to be accelerated.
Except the above-mentioned residence reselecting based on skew, terminal can need to be switched the resonance frequency of receiver to the measurement of different frequent points, common frequency measurement does not need, LTE divides into groups all neighbor cells by frequency, the terminal first absolute priority based on frequency sorts, and finds the frequency of limit priority, then in this frequency, by the residence reselecting based on skew, selectes the Yi Ge community, this reselecting method is called as the reselecting method of Priority-based, is defined as follows:
Condition 1: the S of tested frequency Shang Yige community
nonServingCell, xvalue is at Treselection
rATall be greater than threshold T hresh in time
x, high.Wherein, x means tested frequency, and nonServingCell means tested community, S
nonServingCell, xthe measurement level that means tested community, Treselection
rATmean the cell reselection Measuring Time.Thresh
x, highto high priority frequency gravity treatment thresholding.
Particularly, based on above-mentioned condition 1, can be in conjunction with following judgment rule when carrying out cell reselection:
(1) if a certain community in high priority frequency satisfies condition 1, and terminal is at current persistent district more than resident 1 second, gravity treatment Dao Gai community.
(2) there is no the re eligible community when the resident frequency frequency equal with priority, the high priority frequency point cell does not satisfy condition 1, in addition the measurement level S of persistent district
servingCelllower than thresholding Thresh
serving, low, the S when tested low priority frequency Shang Yige community
nonServingCell, xvalue is at Treselection
rATall be greater than threshold T hresh in time
x, lowthe time, gravity treatment Dao Gai community.Wherein, x means tested low priority frequency, S
nonServingCell, xthe measurement level that means tested community, Treselection
rATmean the cell reselection Measuring Time.Thresh
serving, lowmean persistent district low level thresholding, Thresh
x, lowto low priority frequency gravity treatment thresholding.In addition, if on current frequency best cell be can't gravity treatment community, for example the ，Gai community is prohibited, and this community do not allow terminal do again frequently in gravity treatment, so terminal can be required gravity treatment to priority equate or low frequency on;
(3) press the residence reselecting gravity treatment based on skew for gravity treatment in co-frequency cell and same priority frequency point cell;
(4) in the frequency equal in one or more priority, have a plurality of communities to satisfy condition 1 the time, terminal is selected the Target cell of best cell as gravity treatment.
When based on above-mentioned rule, carrying out cell reselection, need the priority that important parameter is frequency of reference.Usually, frequency and its precedence information can be broadcasted in system message, now, and because all terminals of receiving that system message is broadcasted are all followed identical rule and parameter, so their cell reselection behavior is the same.But the parameters such as these priority are to configure from the angle of the network planning, due to the requirement difference of terminal use for business, will cause different priority tendencies.For example, in order to improve terminal use's business experience, operator may plan speech business and general downloading service on a frequency (being called for short F1) simultaneously, can plan separately the downloading service of a frequency (being called for short F2) for high flow capacity simultaneously.For the general user, can tend to preferably reside in F1 upper, this is because speech business is the main business that these user terminals carry out, and less demanding to what download; But, for high-end user, can tend to reside in F2 upper, because the data that the main business that high-end user carries out is high flow capacity are downloaded.
Be different from the application of the priority of broadcast in order to adapt to certain customers, network can be also separately frequency and the priority of this terminal-specific of terminal distribution (configuration) by dedicated signaling.Now, because network has been broadcasted a set of frequency and relevant priority, so have the coordination problem between two cover priority parameters (frequency distributed separately and frequency and the priority of priority and broadcast), in current communication system, mainly by following rule, complete coordination:
Rule 1: a terminal gravity treatment, to the frequency of broadcasting in system message, that is to say, the frequency occurred in dedicated signaling is the some or all of of system message intermediate-frequeney point, and unnecessary frequency will can not be used;
Rule 2: the priority of the identical frequency occurred in the priority meeting covering system message occurred in dedicated signaling wherein, does not have the situation of priority can be covered equally for the frequency in system message;
Rule 3: the frequency occurred in dedicated signaling were it not for priority, so when fast mobile terminal on this frequency the time, think that the priority of this frequency is stipulated all common priority lower than agreement.
But, when certain frequency and priority only appear in system message (in dedicated signaling not this frequency and corresponding priority), terminal will be ignored this frequency when carrying out cell reselection, make terminal can't gravity treatment to the community of this frequency.If this terminal of Carrier Requirements can gravity treatment to this frequency, must be in dedicated signaling additional this frequency and corresponding priority more separately.
At honeycomb mobile communcations system intermediate-frequeney point, often adopt the method for absolute frequency point number (ARFCN) to mean, (for example can occupy the byte of certain-length, 2 bytes), that adds priority (for example arranges length, to adopt 3 bits in the LTE system), this obviously can increase the expense of wave point signaling.
Geographic location and the network planning on every side of the frequency of broadcasting in the system message of certain community in addition, and priority He Gai community are relevant.As shown in Figure 1, suppose that terminal 1 obtains special-purpose frequency (F1 and F2) and priority thereof by dedicated signaling in community.When fast mobile terminal when the community 2 because do not comprise the information of frequency F3 and priority thereof in dedicated signaling, thus terminal can't gravity treatment to frequency F3 community.Only have when the effective time of special-purpose frequency and priority thereof is overtime or the community of terminal overlapping other frequencies (F1 or F2) at certain and frequency F3 on again by dedicated signaling, obtain the priority of frequency F3, this can't gravity treatment just can the elimination to the phenomenon of frequency F3.
At present, the problem of the signaling consumption outside can occupying volume during the frequency that do not occur in dedicated signaling for terminal gravity treatment in correlation technique, not yet propose effective solution at present.

Functional overview
The problem of the signaling consumption outside can occupying volume during frequency that in correlation technique, the terminal gravity treatment does not occur in dedicated signaling, the present invention proposes: when terminal selection or gravity treatment Dao Yige community, make terminal according to the frequency of knowing at former persistent district and corresponding priority, and the priority of the frequency of knowing by the system broadcasts community in the community of current selection or gravity treatment further combined with terminal and correspondence is carried out cell reselection, avoided carrying out the problem of frequency and priority notice occupying volume external signalling expense by dedicated signaling in current resident community, make terminal can know the reference of the priority of comprehensive frequency and correspondence as gravity treatment, optimized the process of cell reselection.
Describe the specific embodiment of the invention in detail below in conjunction with accompanying drawing.
Embodiment of the method
A kind of implementation method of cell reselection is provided in the present embodiment.
Fig. 2 is the flow chart according to the implementation method of the cell reselection of the embodiment of the present invention, it should be noted that, the step of describing in following methods can be carried out in the computer system such as one group of computer executable instructions, and, although figure 2 illustrates logical order, but in some cases, can carry out step shown or that describe with the order be different from herein.
As shown in Figure 2, comprise step S202 and step S204 according to the implementation method of the cell reselection of the present embodiment.
Concrete processing procedure shown in Fig. 2 is as follows:
Step S202, in the time of terminal selection or gravity treatment Dao Yige community, terminal is in community receiving system broadcast and be informed in the frequency point information of this wireless access technology of community and corresponding gravity treatment priority or other wireless access technology information (corresponding to different systems, these other wireless access technology information can be frequency point information, frequency group information, band information etc.) and corresponding gravity treatment priority;
Step S204, the frequency point information of the gravity treatment priority of the wireless access technology information that terminal is configured in advance according to it and correspondence and this extra wireless access technology of knowing by system broadcast message and corresponding gravity treatment priority or other wireless access technology information and corresponding gravity treatment priority are carried out cell reselection.
That is to say, in terminal, resident from it the first community is selected or gravity treatment during to the second community, and terminal can and be known frequency and the corresponding frequency priority of the access technology (above-mentioned access technology) of the second community in the second community receiving system broadcast; Afterwards, the frequency that terminal can be configured in advance according to it and corresponding frequency priority (select or gravity treatment to the frequency and the corresponding frequency priority that just have been configured before the second community) and frequency and the corresponding frequency priority by system broadcast message, known carry out cell reselection.
Wherein, before step S202,, in terminal, from the first community, select or gravity treatment to before the second community, network by dedicated signaling to terminal configuration in this wireless access technology frequency point information and corresponding gravity treatment priority or other wireless access technology information and corresponding gravity treatment priority, that is, network can carry out the pre-configured of frequency and corresponding priority to terminal during terminal resides in the first community, or can more early to terminal, carry out pre-configured.
Frequency point information or other wireless access technology information of above-mentioned extra this wireless access technology comprise: terminal by system broadcast message, know but not by dedicated signaling frequency point information or other wireless access technology information of this pre-configured wireless access technology.
Particularly, when terminal is carried out cell reselection, if the frequency that terminal is known by system broadcast message comprises that other frequency outside the frequency that terminal is configured in advance (, system broadcast message in the second community comprises new frequency and corresponding priority), the frequency that terminal can be configured in advance according to it and corresponding frequency priority and other frequency and corresponding frequency priority are carried out cell reselection, thereby make the terminal can be with further reference to the frequency of knowing in the second community and priority when carrying out cell reselection.Preferably, terminal can be preserved the frequency priority of other frequency and correspondence in order to carrying out afterwards the gravity treatment of community.And, in the situation that terminal is selected or gravity treatment to other community outside the second community, terminal is removed other frequency and the corresponding frequency priority of preserving, that is to say, the new frequency of knowing in the second community and corresponding frequency priority (that is, the frequency point information of above-mentioned this wireless access technology additionally and corresponding gravity treatment priority or other wireless access technology information and corresponding gravity treatment priority) can only be used in the second community.
On the other hand, the frequency of knowing by system broadcast message in terminal does not comprise that other frequency outside the frequency that terminal is configured in advance (, do not comprise new frequency in system broadcast message in the second community), the frequency that terminal can be configured in advance according to it and corresponding frequency priority are carried out cell reselection.
By above-mentioned processing, make the terminal to know new frequency and corresponding priority by broadcast, thereby saved in the dedicated signaling signaling consumption about frequency and priority.
Processing procedure below in conjunction with different scene descriptions according to the residence reselecting of the embodiment of the present invention.
Example 1
As shown in Figure 3, in this example, suppose in network to have planned 3 frequencies, the dedicated signaling of the former persistent district of terminal (community A) only configured frequency F1 and corresponding priority P be 1 and frequency F2 and corresponding priority P be 3, terminal select or gravity treatment Dao community B in system broadcast message in broadcasted that frequency F1 and corresponding priority P are 1, frequency F2 and corresponding priority P be 3 and frequency F3 and corresponding priority P be 5.
Suppose that priority that frequency that this terminal finally needs and priority are F1 is 3, the priority of F2 be 1 and the priority of F3 be 5.Now, due to the priority of the priority of F3 and Cell Broadcast CB always, as long as comprise in dedicated signaling that so the priority of frequency F1 and F2 is just passable.In terminal, from community A, select or gravity treatment in the B of community, because the frequency F3 broadcasted in the B of this community and priority thereof are 5, so terminal, in the B of community, finally will be obtained, the priority of F1 is 3, the priority of F2 is 1, and to inherit F3 and the priority thereof broadcasted in the B of community be 5.Can find out, process by this, make terminal to know new frequency and corresponding priority by broadcast, thereby save in the dedicated signaling signaling consumption about frequency and priority.
Example 2
As shown in Figure 4, in this example, terminal has been obtained the priority (with similar in example 1, the corresponding priority of F1 is that the corresponding priority of 1, F2 is that the corresponding priority of 3, F3 is 5) of frequency F1, F2 and F3 by dedicated signaling at community A.Then, terminal has been selected community C from community A.When choosing community C, because the frequency of broadcasting in the C of community overlaps with the frequency configured by dedicated signaling in the A of community with the frequency of configuration to terminal, so terminal is not inherited the priority of new frequency and new frequency.But, when community C is arrived in the terminal gravity treatment, because in the frequency of the special use that the frequency F4 broadcasted in system message is known by dedicated signaling before being unexistent (, F4 is new frequency), so terminal has been inherited the priority 7 of the frequency F4 in the B of community, this makes likely gravity treatment frequency F4Shang community D of terminal, now, terminal only just can be known new frequency and priority by system broadcast message, has saved extra dedicated signaling expense.
Afterwards, when terminal again gravity treatment to the E of community the time, because no longer include the information of frequency F4 and priority thereof in the frequency of Cell Broadcast CB, so the priority of the frequency F4 inherited in the B of community can be removed.Process by this, make terminal to know new frequency and corresponding priority by broadcast, thereby saved in the dedicated signaling signaling consumption about frequency and priority.
Example 3
As shown in Figure 5, in this example, terminal has been obtained the priority (with similar in example 1, the corresponding priority of F1 is that the corresponding priority of 1, F2 is that the corresponding priority of 3, F3 is 5) of frequency F1, F2 and F3 at LTE community, community A by dedicated signaling.Then, terminal is selected LiaoLTE community C from community A.Adjacent one another are between the community B of community C and UTRAN system, and the main business of the user in the C of community is speech business, so broadcasted the priority of the frequency F4 of UTRAN system in the C of community, is 7.Terminal just can inherit community C when it chooses community C in the priority 7 of frequency F4 of system broadcast message, and do not need dedicated signaling that the priority of frequency F4 7 is notified to terminal, make the community B of terminal gravity treatment with comparalive ease to UTRAN, can also optimize the quality of the business of terminal execution, improve the user and experience.
Example 4
As shown in Figure 6, terminal disposes the priority (with similar in example 1, the corresponding priority of F1 is that the corresponding priority of 1, F2 is that the corresponding priority of 3, F3 is 5) of special-purpose frequency F1, F2 and F3 at community A.Suppose that terminal has moved to community C from community A, now, because community C is not the suitable cell (suitable cell) of this terminal, and be the acceptable cell (acceptable cell) of terminal, therefore, special-purpose frequency and the priority thereof of configuration before terminal retains, but in the C of community, only use frequency and the priority thereof of community C broadcast to carry out cell reselection.
Example 5
In this example, as shown in Figure 7, terminal disposes the priority (with similar in example 1, the corresponding priority of F1 is that the corresponding priority of 1, F2 is that the corresponding priority of 3, F3 is 5) of special-purpose frequency F1, F2 and F3 at community A.Suppose that terminal has moved to the C of C ， community, community except frequency F1, F2 and F3 and priority thereof from community A, also broadcasted frequency F4, but do not broadcast the priority of F4.Now, it is in order to configure in the special-purpose frequency of terminal and priority thereof, comprising frequency F4 that network is only broadcasted frequency, make the part terminal can gravity treatment to frequency F4.In this case, because frequency 4 does not have effective priority to use, so terminal will no longer be inherited frequency F4.
By the processing according to the present embodiment, make the terminal to know new frequency and corresponding priority by broadcast, thereby saved in the dedicated signaling signaling consumption about frequency and priority.

Preferably, the frequency point information of above-mentioned extra this wireless access technology and corresponding gravity treatment priority or other wireless access technology information and corresponding gravity treatment priority only in the current community that obtains system broadcast message effectively.
And, re-selection process module 2 is used in the situation of other frequency (frequency point information of this extra wireless access technology and corresponding gravity treatment priority or other wireless access technology information and corresponding gravity treatment priority) outside the frequency that frequency that terminal knows by system broadcast message do not comprise that terminal is configured in advance, and the frequency be configured in advance according to terminal and corresponding frequency priority are carried out cell reselection.
