Specific implementation mode
The embodiment of the present application provides a kind of method, apparatus and computer storage media of determining candidate cell, to solve
Certainly how to ensure terminal can with gravity treatment or be switched to support its business alien-frequency district on, to ensure being normally carried out for terminal traffic
The problem of.
First, the part term in the application is explained, in order to those skilled in the art understand that.
First, slice type and frequency point.
There are mainly three types of the slice types that current 5G is supported, but is not limited to three kinds, also, under each slice type again
May include a variety of specific slice types, the application for convenience of description, only with three kinds of slice types, and is not related to every
Include illustrating for which specific slice type under kind of slice type；Specifically, three kinds of slice types may include：
The mobile broadband technology (Enhance Mobile Broadband, eMBB) of enhancing, low time delay high reliable communication (Ultra-
Reliable and Low Latency Communication, URLLC) and magnanimity machine type communication (Massive Type
of Communication,mMTC)。
Also, there is certain relationships with slice type for frequency point, wherein disposes the scene of slice type in network side
When, different subdistrict frequency points can dispose different slice types, and the slice type supported on same subdistrict frequency point is identical
, i.e., slice type has certain corresponding relationship with subdistrict frequency point.
Second, wireless heterogeneous networks (Radio Resource Control, RRC) Connection Release signaling.
When network side release is connect with the RRC of terminal, network side can send release signaling, and release signaling to terminal
In, carry redirection information and/or subdistrict frequency point precedence information, wherein redirection information is used to specify one to terminal
Specific subdistrict frequency point, after network side release is connect with the RRC of terminal, terminal can only carry out on the specific subdistrict frequency point
Cell reselection；Subdistrict frequency point precedence information is used to carry out the priority of the subdistrict frequency point of cell reselection to terminal instruction.
Also, when the information difference carried in release signaling, terminal would also vary from when carrying out cell reselection,
In, may include following several situations：
If only carry subdistrict frequency point precedence information in release signaling, discharges in network side and connect with the RRC of terminal
Afterwards, terminal is selected first in current area and is resident, then according to the subdistrict frequency point precedence information carried in release signaling into
Row cell reselection.
If only carry redirection information in release signaling, after network side release is connect with the RRC of terminal, terminal is first
Cell reselection first is carried out according to the subdistrict frequency point specified in redirection information, then carries out common cell in resident cell
Gravity treatment.
If carry redirection information and subdistrict frequency point precedence information in release signaling, in network side release and terminal
RRC connections after, terminal first, in accordance in redirection information specify subdistrict frequency point carry out cell reselection, then according to release believe
The subdistrict frequency point precedence information carried in order carries out cell reselection.
If both not carrying redirection information in release signaling, also when no carrying subdistrict frequency point precedence information,
Network side release connect with the RRC of terminal after, terminal is selected first in current area and is resident, then be resident cell in into
The common cell reselection of row.
Secondly, inventor has found under study for action, currently, terminal is when carrying out cell reselection, the cell between co-frequency cell
Gravity treatment do not need to consider slice type limitation, and between alien-frequency district cell reselection or switching, then need to consider
The limitation of slice type is needed to ensure gravity treatment or is switched on the alien-frequency district for supporting its business, to meet the normal of business
It carries out, terminal is avoided frequently to carry out alien-frequency district gravity treatment or switching and lead to service disconnection.
Also, in the prior art, when terminal is needed using some slice type, it is believed that the slice type of network side
It is always available, as long as so when terminal carries out cell reselection based on the gravity treatment priority that network side configures, which would not
It is resident in the corresponding slice type unmatched cell of slice type corresponding with terminal；However, network side is in software and hardware liter
In the case of grade or Network Abnormal, it may result in certain slice types and be disabled temporarily, so that terminal can not obtain
It is serviced to desired slice, finally reduces user experience.
Based on this, the embodiment of the present application provides a kind of method of determining candidate cell, be suitable for network side, such as base station,
This method may comprise steps of：
Step 1: network side determines the corresponding slice type in end side.
Network side may be used well-known to those skilled in the art any when determining the corresponding slice type in end side
The mode that can determine the corresponding slice type in end side, is not limited thereto.
Step 2: when meeting preset condition, slice type of the network side corresponding to currently available subdistrict frequency point, really
The candidate cell frequency point information that fixed slice type corresponding with end side matches.
In the specific implementation, it is network in preset condition since different slice types corresponds to different types of service
When side can not provide the corresponding slice type in end side, it is equivalent to, network side can no longer meet the business demand of end side, be
Ensure that the business of terminal is not interrupted, terminal needs to access other networks (i.e. base station) as soon as possible to continue the business, thus net
Network side is it needs to be determined that go out the candidate cell frequency point information that slice type corresponding with terminal matches, in order to which terminal carries out cell
Gravity treatment.Certainly, preset condition, which is not limited to the above-mentioned network side referred to, can not provide terminal corresponding slice type, can also be
Other-end needs to carry out the condition of cell reselection, is not limited thereto.
Also, network side will not only determine candidate cell frequency point, and the priority of candidate cell frequency point is also predefined out, with
Cell reselection can be carried out convenient for terminal according to the priority of candidate cell frequency point so that terminal priority access can provide more preferably
In the cell of service, to ensure being normally carried out for terminal traffic；Therefore, candidate cell frequency point information may include following message：
Candidate cell frequency point and candidate cell frequency point priority；Wherein, candidate cell frequency point priority can be according to candidate cell frequency point
Load determine, specifically determine that the mode of candidate cell frequency point priority is as follows：
First, it can determine candidate cell frequency point priority according only to the loading condition of candidate cell frequency point, that is, be directed to
Each candidate cell frequency point, if the load of the candidate cell frequency point is lower, the candidate cell frequency point priority is higher, if the time
Select the load of subdistrict frequency point higher, certain candidate cell frequency point priority is lower.
For example, if the slice type set by current network side has tri- kinds of eMBB, mMTC and URLLC, and currently available cell
Frequency point has 5, and corresponding slice type and loading condition are as follows：
Subdistrict frequency point 1, low-load support mMTC；
Subdistrict frequency point 2, low-load support eMBB and mMTC；
Subdistrict frequency point 3, high load support URLLC and eMBB；
EMBB is supported in subdistrict frequency point 4, middle load；
URLLC is supported in subdistrict frequency point 5, middle load.
If the corresponding slice type of terminal is eMBB, and when network side can not provide terminal corresponding slice type, network
Candidate cell frequency point is determined in side according to the corresponding slice type eMBB of terminal first, that is, determines subdistrict frequency point 2, subdistrict frequency point
3 and subdistrict frequency point 4；Then, since subdistrict frequency point 2 is low-load, subdistrict frequency point 3 is high load, and subdistrict frequency point 4 is middle load,
So according to the loading condition of candidate cell frequency point, determine that candidate cell frequency point priority is：The priority of subdistrict frequency point 2 is
5, the priority of subdistrict frequency point 4 is 3, and the priority of subdistrict frequency point 3 is 1, that is to say, that the highest priority of subdistrict frequency point 2, small
Area's frequency point 4 secondly, the priority of subdistrict frequency point 3 it is minimum.
By the above method it is found that being cut determining that the corresponding slice type of candidate cell frequency point is corresponding with terminal first
Under the premise of sheet type matches, then determine by the loading condition of candidate cell frequency point the priority of candidate cell frequency point, no
It can only so that terminal subdistrict frequency point of selection when carrying out cell reselection is to support the corresponding slice type of terminal, and then make
Corresponding business can be continued by obtaining terminal, and can also effectively reduce the probability of access failure, ensure the normal of terminal traffic
It carries out, ensures the stability of business, improve user experience.
Second, can according to the loading condition of candidate cell frequency point, slice type corresponding to candidate cell frequency point when
How much the type for prolonging the slice type corresponding to requirement size and candidate cell frequency point determines that candidate cell frequency point is preferential
Grade.Therefore, it firstly, it is necessary to determine that candidate cell frequency point is the subdistrict frequency point for being currently at non-full load, so will can completely bear
The subdistrict frequency point of load excludes, and to avoid the access failure occurred when accessing cell at full capacity, influences user experience.
Then, for each candidate cell frequency point, if the delay requirement of the slice type corresponding to the candidate cell frequency point
It is higher, if and/or slice type corresponding to the candidate cell frequency point type it is more, the priority of the candidate cell frequency point
It is higher, if on the contrary, the delay requirement of the slice type corresponding to the candidate cell frequency point is lower, and the candidate cell frequency point institute is right
The type for the slice type answered is fewer, and the priority of certain candidate cell frequency point is also lower.It should be noted that here
Delay requirement refers to time delay tolerance, that is to say, that delay requirement is higher, i.e., has the time compared with strict requirements, then time delay
Tolerance is relatively low, conversely, delay requirement is relatively low, then time delay tolerance is higher.
For example, if the slice type set by current network side equally has tri- kinds of eMBB, mMTC and URLLC, and it is currently available
Subdistrict frequency point has 5, and corresponding slice type and loading condition are as follows：
Subdistrict frequency point 1, low-load support mMTC；
Subdistrict frequency point 2, low-load support URLLC and mMTC；
Subdistrict frequency point 3, full load support URLLC and eMBB；
Subdistrict frequency point 4, low-load support URLLC；
Subdistrict frequency point 5, low-load support eMBB.
If the corresponding slice type of terminal is mMTC and two kinds of URLLC, and network side can not provide terminal corresponding slice
When type, network side determines candidate cell frequency point according to the corresponding slice type mMTC and URLLC of terminal first, that is, determines
Subdistrict frequency point 1, subdistrict frequency point 2 and subdistrict frequency point 4, since subdistrict frequency point 3 is full load, the slice type that subdistrict frequency point 5 is supported
Slice type corresponding with terminal mismatches, so subdistrict frequency point 3 and subdistrict frequency point 5 are excluded；Then, due to URLLC when
The time delay tolerance of eMTC will be significantly less than by prolonging tolerance, so according only to the slice type corresponding to candidate cell frequency point
When delay requirement size determines candidate cell frequency point priority, the priority of subdistrict frequency point 1 is minimum, and subdistrict frequency point 2 and cell
The priority of frequency point 4 is higher than subdistrict frequency point 1.
In another example above-mentioned candidate cell frequency point priority be slice type corresponding to candidate cell frequency point when
Prolong requirement size to determine, but it is not limited to this, can also be according only to the kind of the slice type corresponding to candidate cell frequency point
How much class determines that the candidate cell frequency point highest priority determined is subdistrict frequency point 2, and subdistrict frequency point 1 and cell
The type of slice type corresponding to frequency point 4 is one, so priority is identical.
In another example can also the first slice type corresponding to candidate cell frequency point delay requirement size, further according to
How much the type of slice type corresponding to candidate cell frequency point determine, therefore, it is first determined go out priority it is minimum be small
The priority of area's frequency point 1, subdistrict frequency point 2 and subdistrict frequency point 4 is above subdistrict frequency point 1；Then it is cut since subdistrict frequency point 2 is corresponding
The type of sheet type will be more than 4 corresponding slice type of subdistrict frequency point type, so the priority of subdistrict frequency point 2 be higher than it is small
Area's frequency point 4, therefore, the sequence of the candidate cell frequency point priority finally determined from high to low is：Subdistrict frequency point 2, cell frequency
Point 4, subdistrict frequency point 1, that is to say, that the highest priority of subdistrict frequency point 2, subdistrict frequency point 4 secondly, the priority of subdistrict frequency point 1
It is minimum.
In another example can also first the slice type corresponding to candidate cell frequency point type how much, further according to candidate
Therefore, it is first determined go out highest priority is small the delay requirement size of slice type corresponding to subdistrict frequency point determines,
Area's frequency point is 2, and subdistrict frequency point 4 is identical with the priority of subdistrict frequency point 1；Then since the time delay tolerance of URLLC is apparent small
In the time delay tolerance of eMTC, so the priority of subdistrict frequency point 4 is higher than the priority of subdistrict frequency point 1；Therefore, it finally determines
Candidate cell frequency point priority sequence from high to low be：Subdistrict frequency point 2, subdistrict frequency point 4, subdistrict frequency point 1, that is to say, that
The highest priority of subdistrict frequency point 2, secondly, the priority of subdistrict frequency point 1 is minimum for subdistrict frequency point 4.
By the above method it is found that being cut determining that the corresponding slice type of candidate cell frequency point is corresponding with terminal first
Under the premise of sheet type matches, then by the loading condition of candidate cell frequency point, the slice class corresponding to candidate cell frequency point
How much the delay requirement size of type and the type of the slice type corresponding to candidate cell frequency point determine candidate cell frequency point
Priority can not only so that terminal subdistrict frequency point of selection when carrying out cell reselection is to support the corresponding slice type of terminal
, so that terminal can continue corresponding business, the probability of access failure can also be effectively reduced, ensures terminal traffic
It is normally carried out, ensures the stability of business, improve user experience.
It should be pointed out that in the embodiment of the present application, when determining candidate cell frequency point priority, however it is not limited to above-mentioned
The delay requirement referred to can also be other indexs related with the performance of slice type, be not limited thereto.
In addition, in applying for embodiment, after network side determines candidate cell frequency point information, network side release with
When the network connection of terminal, terminal can enter idle state, at this point, terminal can be small according to the release signaling progress that network is sent
Area's gravity treatment；Therefore, the embodiment of the present application can also provide a kind of method of cell reselection, as shown in Figure 1, including the following steps：
S101, network side determine the corresponding slice type in end side；
S102, when meeting preset condition, slice type of the network side corresponding to currently available subdistrict frequency point, determine
The candidate cell frequency point information that slice type corresponding with end side matches；
Wherein, preset condition, which can be the above-mentioned network side referred to, can not provide end side corresponding slice type, certainly
It is not limited to this.
S103, network side will carry candidate cell frequency point information, Yi Jihou in release and the network connection of end side
The release signaling of the information of the effective time of subdistrict frequency point information is selected to be sent to end side；
Wherein, network connection can be RRC connections, and after network side release is connect with the RRC of end side, terminal is placed on
Idle state, in order to which end side carries out cell reselection.
S104, end side receive the release signaling that network side is sent；
S105, end side are according to the candidate cell frequency point information and candidate cell frequency point information carried in release signaling
Effective time information, carry out cell reselection.
It should be pointed out that terminal, when carrying out cell reselection, the subdistrict frequency point precedence information of use can be by following
Two ways provides：
First, common signaling, i.e. system information, which provide the precedence information of current area frequency point, E-UTRAN its
The respective precedence information of the respective precedence information of his frequency point and each frequency point of other RAT.
Second is that dedicated signaling, optionally carries E-UTRAN different frequency/different technology frequency points in RRC Connection Release signalings
Priority list and corresponding effective time information；And dedicated signaling increases compared with common signaling in dedicated signaling
Effective time information.
It is provided according to existing LTE standard, when terminal carries out cell reselection, if terminal does not receive dedicated signaling instruction
When special priority information, terminal is measured using the public priority provided in system information and cell reselection；If terminal
When receiving dedicated signaling instruction special priority information, any public precedence information will not be considered any further in terminal, until special
The term of validity timer expiry of precedence information or due to other reasons terminate after, terminal can just abandon special priority information,
And restart to carry out corresponding measurement and cell reselection based on public precedence information.
Therefore, the release signaling referred in the application is denoted as dedicated signaling, is not only carried in release signaling candidate small
Area's frequency point information also carries the information of the effective time of candidate cell frequency point information, and effective time can pass through setting
It is controlled in the timer of terminal, i.e., when terminal receives the release signaling of network side transmission, just starts timer and start
Timing, until effective time terminates or due to other reasons and after terminating, terminal then abandons the release signaling, using public preferential
Grade information carries out cell reselection.
To sum up, in network side, such as specifically in base station, the embodiment of the present application provides a kind of side of determining candidate cell
Method, as shown in Fig. 2, this method may include：
S201, the corresponding slice type in end side is determined；
S202, when meeting preset condition, according to the slice type corresponding to currently available subdistrict frequency point, determine and terminal
The candidate cell frequency point information that the corresponding slice type in side matches.
In this way, can determine to answer with terminal-pair according to the slice type corresponding to currently available subdistrict frequency point
The candidate cell frequency point information that matches of slice type, i.e., candidate cell frequency point information is determined according to slice type, to protect
Card terminal traffic is normally carried out, and is avoided being sliced unavailable caused terminal access failure, is improved user experience.
Optionally, in the embodiment of the present application, candidate cell frequency point information may include following message：Candidate cell frequency
Point, candidate cell frequency point priority.
In this way, terminal can be conducive to when carrying out cell reselection, can be carried out according to the priority of candidate cell frequency point
Selection, so that terminal can obtain the slice of better services with priority access, ensures being normally carried out for terminal traffic.
Optionally, in order to determine that candidate cell frequency point is preferential, in the embodiment of the present application, candidate cell frequency point is preferential
Grade is determining according to the load of candidate cell frequency point.
So so that the lower candidate cell frequency point priority of load is higher, and loads higher candidate cell frequency point
Priority is lower, leads to access failure so as to effectively avoid terminal from choosing in the cell in full load.
Optionally, candidate cell frequency point priority can be determined according only to loading condition, so, in the embodiment of the present application
In, for each candidate cell frequency point, if the load of the candidate cell frequency point is lower, which gets over
It is high.
In this way, terminal can be conducive to when carrying out cell reselection, avoid choosing in the cell in full load and leading
Access failure is caused, the probability of access failure is reduced.
Optionally, in the embodiment of the present application, when candidate cell frequency point is to be currently at the subdistrict frequency point of non-full load,
For each candidate cell frequency point, if the delay requirement of the slice type corresponding to the candidate cell frequency point is higher, if and/or should
The type of slice type corresponding to candidate cell frequency point is more, then the priority of the candidate cell frequency point is higher.
For example, determined according only to the delay requirement size of the slice type corresponding to candidate cell frequency point, i.e. the candidate
The delay requirement of slice type corresponding to subdistrict frequency point is higher, then the priority of the candidate cell frequency point is higher, to advantageous
