Detailed Description
The existing same-frequency reselection scheme is as follows: and detecting the signal intensity of the current cell, acquiring the signal intensity of adjacent cells under the condition of the reselection threshold of the signal intensity cell of the current cell, and selecting the adjacent cell with the same frequency with the optimal signal intensity as a candidate cell from the adjacent cells with the same frequency with the signal intensity greater than the candidate threshold. In order to avoid co-channel interference caused by the fact that the terminal resides in a second best cell, the terminal selects a resident cell according to the signal intensity without considering the slicing condition supported by the cell; however, in the existing common-frequency reselection scheme, if the reselected cell does not support the slice supported by the terminal, although Radio Resource Control (RRC) connection can be established, service cannot be initiated, unnecessary signaling overhead is caused, and user experience is also affected.
Or, if the user resides in a cell that does not support terminal slicing, after RRC connection release, the user still selects the cell for access next time if the cell has the strongest signal strength, because the service cannot be initiated, so that the service cannot be initiated all the time.
To make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, at least one embodiment of the present disclosure provides a configuration method for co-frequency reselection, which is applied to a network side device, and includes:
and 11, sending a broadcast message, wherein the broadcast message carries a cell blacklist for carrying out co-frequency reselection by the terminal based on the slice.
The network side device is a cell where the terminal currently resides.
As at least one embodiment of the present disclosure, the method further comprises:
acquiring a slice type supported by a neighbor cell;
and determining the cell blacklist according to the slice types supported by the adjacent cells and the slice types supported by the network side equipment.
As another optional embodiment of the present disclosure, the cell blacklist includes a different slice type supported by a blacklisted cell from a slice type supported by the network side device.
When the Xn port is established, the adjacent cells intercommunicate the supported slice information. In order to avoid that the terminal reselects the cell which does not support the slice supported by the terminal through the signal quality intensity, the current resident cell places the neighboring cell which supports the slice type different from that of the cell in the system message in a cell blacklist of the same frequency reselection and broadcasts the neighboring cell to all terminals resident in the cell. Through the configuration of the cell blacklist, all terminal common frequencies residing in the cell can be prevented from reselecting the cell which does not support the terminal slice type.
For example, the terminal supports slice 1, currently resides in cell1, cell1 supports slice 1 only, cell 2 supports slice 2 only, and both cell1 and cell 2 belong to 2.6G frequency points. When the cell1 finds that the slice types supported by the cell 2 are different, the cell 2 is put into a cell blacklist reselected under the same frequency and broadcasted, and the terminal cannot reselect the cell 2 after acquiring the broadcast message.
In at least one embodiment of the disclosure, a cell blacklist for the terminal to perform co-frequency reselection based on slices is carried in a broadcast message, so that the terminal can be prevented from performing co-frequency reselection to a cell which does not support the slices of the terminal.
As shown in fig. 2, at least one embodiment of the present disclosure further provides an intra-frequency reselection method, applied to a terminal, including:
and step 22, performing cell reselection in other co-frequency cells except the cell blacklist according to the broadcast message.
As at least one embodiment of the present disclosure, the cell blacklist includes a different slice type supported by a blacklisted cell than a serving cell currently accessed by the terminal.
The network side device is a cell where the terminal currently resides. In order to avoid that the terminal reselects the cell which does not support the slice supported by the terminal through the signal quality intensity, the current resident cell places the neighboring cell which supports the slice type different from that of the cell in the system message in a cell blacklist of the same frequency reselection and broadcasts the neighboring cell to all terminals resident in the cell. Through the configuration of the cell blacklist, all terminal common frequencies residing in the cell can be prevented from reselecting the cell which does not support the terminal slice type.
In at least one embodiment of the disclosure, a cell blacklist for the terminal to perform co-frequency reselection based on slices is carried in a broadcast message, so that the terminal can be prevented from performing co-frequency reselection to a cell which does not support the slices of the terminal.
The above-mentioned manner of adding the cell blacklist in the broadcast message is only suitable for the case where the slice types supported by the source cell and the neighboring cell are completely different, but is not suitable for the scenario where the slice types supported by the source cell and the neighboring cell are partially the same. For example, if cell1 supports slice 1 and slice 2, and cell 2 with the same frequency supports slice 2 and slice 3, the method of adding cell 2 to the cell black list is not appropriate for cell1, since the terminal residing in cell1 may also support slice 2. Therefore, for a situation that a terminal resides in a cell that does not support terminal slicing and cannot initiate a service, as shown in fig. 3, at least one embodiment of the present disclosure further provides a configuration method for co-frequency reselection, which is applied to a network side device, and includes:
In at least one embodiment of the present disclosure, if the terminal reselects a cell that does not support terminal slicing, a service cannot be initiated. At this time, when the terminal releases the connection overtime, the network side device adds a slice type priority (sliceTypepriority) field in the RRC release signaling, configures different slice priorities for the terminal, and guides the terminal to camp again in the cell supporting the slice.
As at least one embodiment of the present disclosure, the RRC release signaling (e.g., slicetypeppriority field) further includes at least one of the following:
a slice set corresponding to the slice priority; the slice set may contain one slice or a plurality of slices;
a neighbor list of a slice set corresponding to the slice priority;
the effective duration of the slice priority.
As shown in table 1, is an example of a slicetypeppriority field.
TABLE 1
Table 1 lists the priority corresponding to each slice set and the neighbor list supporting the slice set. For example, in the first row in table 1, the slice set SST ═ 1 and SST ═ 2 and having the priority 1, the neighborhood corresponding to the simultaneous support of the slices SST ═ 1 and SST ═ 2 is Cell0, the slice set SST ═ 2 and SST ═ 3 and having the priority 2 are Cell1 and Cell0, and the neighborhood corresponding to the simultaneous support of the slices SST ═ 2 and SST ═ 3 is Cell1 and Cell 0.
As at least one embodiment of the present disclosure, before step 31, the method further comprises:
receiving a slice type supported by a terminal reported by the terminal; for example, after the network side device establishes RRC connection with the terminal, the terminal reports slice information (e.g., slice type) of the terminal to the network side device through the message 5.
Accordingly, step 31 comprises:
and sending the RRC release signaling under the condition that the slice type supported by the terminal is different from the slice type supported by the network side equipment.
As an alternative embodiment, the method further comprises:
setting slice priority for a slice set according to the slice types supported by the terminal reported by the terminal;
or,
determining slice priorities of the slice sets according to predefined rules; because the combination forms of the slices are more, the setting rule of the priority is recommended to be customized by an operator, the configuration and reading efficiency is improved, and the conflict problem caused by inconsistent configuration under the networking scene of different manufacturers is avoided. The slicetypeppriority field also contains the corresponding neighbor list that supports each slice set. Meanwhile, a timer is set to the effective time length of limiting the slice priority.
Optionally, setting a slice priority for a slice set according to the slice type supported by the terminal reported by the terminal, including:
setting a slice set containing all slices corresponding to the slice types supported by the terminal as a first priority;
setting a slice set containing partial slices corresponding to the slice types supported by the terminal as a second priority;
and setting the slice set which does not contain the slice corresponding to the slice type supported by the terminal as the third priority.
At least one embodiment of the disclosure includes slice priority in RRC release signaling, and avoids that a user accesses a cell that does not support a slice of a terminal for many times, thereby avoiding a problem that a service cannot be initiated all the time.
As shown in fig. 4, at least one embodiment of the present disclosure further provides an intra-frequency reselection method, applied to a terminal, including:
and 42, performing same-frequency reselection according to the sequence of the slice priority according to the RRC release signaling.
In at least one embodiment of the present disclosure, if the terminal reselects a cell that does not support terminal slicing, a service cannot be initiated. At this time, when the terminal releases the connection overtime, the network side device adds a slice type priority (sliceTypepriority) field in the RRC release signaling, configures the slice priorities of different slice sets for the terminal, and guides the terminal to camp again in the cell supporting the slice.
As at least one embodiment of the present disclosure, the RRC release signaling further includes at least one of:
a slice set corresponding to the slice priority;
a neighbor list of a slice set corresponding to the slice priority;
the effective duration of the slice priority.
As at least one embodiment of the present disclosure, in a case that the RRC release signaling includes an effective duration of the slice priority, step 42 includes:
performing same-frequency reselection according to the sequence of slice priorities within the effective duration;
and after the effective time length is exceeded, performing same-frequency reselection according to the signal intensity.
After configuring a slice priority related field by a base station, before a timer is not overtime, a terminal firstly performs same-frequency reselection according to a slice priority sequence (preferentially selecting a slice priority 1, selecting a slice priority 2 if no supported cell exists, and so on); if the timer is overtime, the slice priority is invalid, and the terminal still performs cell co-frequency reselection according to the signal strength, so that the cell co-frequency reselection can be consistent with the existing specified cell co-frequency reselection principle.
As at least one embodiment of the present disclosure, in a case that the RRC release signaling includes a neighbor list of a slice set corresponding to the slice priority, step 42 includes:
and when the same-frequency reselection is carried out according to the sequence of the slice priorities, if the neighbor cell list of the slice set corresponding to the currently selected slice priority contains at least two neighbor cells, selecting the neighbor cells in the at least two neighbor cells according to the signal intensity.
And if the same priority combination corresponds to a plurality of supported adjacent cells, the terminal further performs cell communication reselection according to the signal strength.
For example, assuming that a terminal supporting slice 1(SST ═ 1, SD ×) resides in Cell1 through Cell co-frequency reselection, but Cell1 only supports slice 2(SST ═ 2, SD ×), the base station needs to add this field in RRC release signaling and set SST ═ 1 to the highest priority. And the terminal performs Cell co-frequency reselection according to the priority, and preferentially reselects the Cell0 of the adjacent Cell corresponding to SST (SST-1). If the first priority has a plurality of corresponding cells, selecting among the plurality of cells according to signal strength. And if the cell corresponding to the first priority is empty, selecting the cell according to the second slice priority, and so on. In addition, when setting the slice priority, a timer needs to be started at the same time, and if the timer is overtime, the user still performs cell co-frequency reselection according to the signal strength.
As at least one embodiment of the present disclosure, the slice priority includes:
a first priority, wherein a slice set corresponding to the first priority comprises all slices corresponding to slice types supported by a terminal;
a second priority, wherein a slice set corresponding to the second priority comprises partial slices corresponding to slice types supported by a terminal;
and a third priority, wherein the slice set corresponding to the third priority does not contain a slice corresponding to a slice type supported by the terminal.
Correspondingly, the performing same-frequency reselection according to the RRC release signaling and the order of slice priorities includes:
performing same-frequency reselection in the slice set with the first priority; if the slice set of the first priority is empty, performing same-frequency reselection in the slice set of the second priority;
and if the slice set of the second priority is empty, performing same-frequency reselection in the slice set of the third priority.
At least one embodiment of the disclosure includes a slice priority in the RRC release signaling, so that a user is prevented from accessing a cell that does not support a slice of a terminal for multiple times, thereby preventing a problem that a service cannot be initiated all the time, and guiding the terminal to reselect to the cell that supports the slice of the terminal.

a first sending module 51, configured to send a broadcast message, where the broadcast message carries a cell blacklist for which a terminal performs intra-frequency reselection based on a slice.
