Detailed ways

The existing co-frequency reselection scheme is as follows: the signal strength of the current cell is detected, and in the case of the cell reselection threshold of the current cell signal strength, the signal strength of the neighboring cell is collected, and in the same-frequency neighboring cell whose signal strength is greater than the candidate threshold, Select the same-frequency neighbor cell with the best signal strength as the candidate cell. That is, in order to prevent the terminal from camping on the sub-optimal cell and causing co-channel interference, the terminal selects the camping cell based on the signal strength, regardless of the slice situation supported by the cell; and in the existing co-frequency reselection scheme, if the reselected cell does not support For slices supported by the terminal, although a radio resource control (RadioResource Control, RRC) connection can be established, services cannot be initiated, causing unnecessary signaling overhead and affecting user experience.

Or, if the user resides in a cell that does not support terminal slicing, because the service cannot be initiated, after the RRC connection is released, if the signal strength of the cell is the strongest next time, the user will still select the cell to access, resulting in the service being unable to initiate. .

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure more clear, detailed description will be given below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , at least one embodiment of the present disclosure provides a method for configuring intra-frequency reselection, which is applied to a network-side device, including:

Step 11: Send a broadcast message, wherein the broadcast message carries a cell blacklist for the terminal to perform intra-frequency reselection based on the slice.

Wherein, the above-mentioned network-side device is the cell where the terminal currently resides.

As at least one embodiment of the present disclosure, the method further includes:

Get the slice types supported by neighboring cells;

The cell blacklist is determined according to the slice type supported by the neighboring cell and the slice type supported by the network side device.

As another optional embodiment of the present disclosure, the slice type supported by the blacklisted cells contained in the cell blacklist is different from the slice type supported by the network side device.

When the Xn interface is established, the supported slice information is exchanged between adjacent cells. In order to prevent the terminal from reselecting to a cell that does not support the slice supported by the terminal based on the signal quality strength, the currently residing cell will put the neighboring cells with different types of slices supported by the current cell in the blacklist of cells for intra-frequency reselection in the system message. And broadcast to all terminals residing in the cell. Through the configuration of the cell blacklist, all terminals residing in the cell can be prevented from reselection to cells that do not support the terminal slice type.

For example, the terminal supports slice 1 and currently resides in cell 1. Cell 1 only supports slice 1, and cell 2 only supports slice 2. Both cell 1 and cell 2 belong to the 2.6G frequency point. Cell 1 finds that cell 2 supports different slice types, and puts cell 2 into the cell blacklist for intra-frequency reselection and broadcasts it. The terminal will not reselect to cell 2 after obtaining the broadcast message.

In at least one embodiment of the present disclosure, by carrying a cell blacklist for the terminal to perform intra-frequency reselection based on slices in the broadcast message, it is possible to prevent the terminal from intra-frequency reselection to a cell that does not support the terminal's slice.

As shown in FIG. 2 , at least one embodiment of the present disclosure further provides a method for intra-frequency reselection, applied to a terminal, including:

Step 21: Receive a broadcast message, where the broadcast message carries a cell blacklist that the terminal performs intra-frequency reselection based on the slice;

Step 22: Perform cell reselection in other intra-frequency cells other than the cell blacklist according to the broadcast message.

As at least one embodiment of the present disclosure, a slice type supported by a blacklisted cell included in the cell blacklist is different from a slice type supported by a serving cell currently accessed by the terminal.

Wherein, the above-mentioned network-side device is the cell where the terminal currently resides. In order to prevent the terminal from reselecting to a cell that does not support the slice supported by the terminal based on the signal quality strength, the currently residing cell will put the neighboring cells with different types of slices supported by the current cell in the blacklist of cells for intra-frequency reselection in the system message. And broadcast to all terminals residing in the cell. Through the configuration of the cell blacklist, all terminals residing in the cell can be prevented from reselection to cells that do not support the terminal slice type.

In at least one embodiment of the present disclosure, by carrying a cell blacklist for the terminal to perform intra-frequency reselection based on slices in the broadcast message, it is possible to prevent the terminal from intra-frequency reselection to a cell that does not support the terminal's slice.

The above method of adding a cell blacklist in the broadcast message is only applicable to the case where the source cell and the neighboring cell support completely different slice types, but are not applicable to the scenario where the source cell and the neighboring cell support some of the same slice types. For example, the terminal is currently residing in cell 1. If cell 1 supports slice 1 and slice 2, and cell 2 on the same frequency supports slice 2 and slice 3, for cell 1, the method of adding cell 2 to the cell blacklist It is not appropriate, because the terminal camping on cell 1 may also support slice 2. Therefore, for a situation where a terminal cannot initiate a service due to camping on a cell that does not support terminal slicing, as shown in FIG. 3 , at least one embodiment of the present disclosure further provides a configuration method for intra-frequency reselection, which is applied to a network side device ,include:

Step 31: Send radio resource control RRC release signaling, wherein the RRC release signaling includes the slice priority corresponding to the terminal.

In at least one embodiment of the present disclosure, if the terminal reselects to a cell that does not support terminal slicing, the service cannot be initiated. At this time, when the terminal releases the connection over time, 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 re-camp in a cell that supports slices.

As at least one embodiment of the present disclosure, the RRC release signaling (such as the sliceTypePriority field) further includes at least one of the following items:

The slice set corresponding to the slice priority; the slice set may include one slice or multiple slices;

the neighbor list of the slice set corresponding to the slice priority;

The effective duration of the slice priority.

As shown in Table 1, it is an example of the sliceTypePriority field.

Table 1

Table 1 lists the priority corresponding to each slice set and the list of neighbors that support the slice set. For example, in the first row of Table 1, the slice set SST=1, SST=2, the priority is 1, the corresponding adjacent cell that supports both slices SST=1 and SST=2 is Cell0, and the slice set SST=2, SST=3 The priority is 2, and the adjacent cells corresponding to the slices SST=2 and SST=3 at the same time are Cell1 and Cell0.

As at least one embodiment of the present disclosure, before step 31, the method further includes:

Receive the slice type supported by the terminal reported by the terminal; for example, after the network side device establishes an RRC connection with the terminal, the terminal reports the terminal slice information (eg slice type) to the network side device through message 5.

Correspondingly, step 31 includes:

In the case that the slice type supported by the terminal is different from the slice type supported by the network side device, the RRC release signaling is sent.

As an optional embodiment, the method further includes:

setting a slice priority for the slice set according to the slice type reported by the terminal and supported by the terminal;

or,

Determine the slice priority of the slice set according to the predefined rules; since there are many combinations of slices, it is recommended that the priority setting rules be customized by the operator to improve the efficiency of configuration and reading, and avoid configuration in different-vendor networking scenarios. Conflicts caused by inconsistencies. The sliceTypePriority field also contains a list of corresponding neighbors that support each slice set. At the same time, a timer is set to limit the effective duration of the slice priority.

Optionally, setting a slice priority for the slice set according to the slice type reported by the terminal and supported by the terminal, including:

Set the slice set containing all slices corresponding to slice types supported by the terminal as the first priority;

Set the slice set containing partial slices corresponding to slice types supported by the terminal to the second priority;

A slice set that does not contain slices corresponding to slice types supported by the terminal is set to the third priority.

At least one embodiment of the present disclosure includes slice priority in the RRC release signaling, so as to prevent the user from repeatedly accessing a cell that does not support slices of the terminal, thereby avoiding the problem that the 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:

Step 41: Receive radio resource control RRC release signaling, where the RRC release signaling includes the slice priority corresponding to the terminal;

Step 42, according to the RRC release signaling, perform intra-frequency reselection according to the sequence of slice priorities.

In at least one embodiment of the present disclosure, if the terminal reselects to a cell that does not support terminal slicing, the service cannot be initiated. At this time, when the terminal releases the connection over time, the network side device adds a slice type priority (sliceTypePriority) field in the RRC release signaling, configures the slice priority of different slice sets for the terminal, and guides the terminal to re-camp in a cell that supports slices .

As at least one embodiment of the present disclosure, the RRC release signaling further includes at least one of the following:

the slice set corresponding to the slice priority;

the neighbor list of the slice set corresponding to the slice priority;

The effective duration of the slice priority.

As at least one embodiment of the present disclosure, when the RRC release signaling includes the effective duration of the slice priority, step 42 includes:

Within the effective time period, perform intra-frequency reselection according to the order of slice priorities;

After the effective time period is exceeded, the same-frequency reselection is performed according to the signal strength.

After the base station configures the slice priority related fields, before the timer expires, the terminal first performs intra-frequency reselection according to the order of slice priority (slice priority 1 is preferred, and if there is no supported cell, slice priority 2 is selected, and then and so on); if the timer expires, the slice priority is invalid, and the terminal still performs cell co-frequency reselection according to the signal strength, which can be consistent with the existing specified cell co-frequency reselection principle.

As at least one embodiment of the present disclosure, when the RRC release signaling includes the neighbor list of the slice set corresponding to the slice priority, step 42 includes:

When performing intra-frequency reselection according to the order of slice priorities, if the neighbor list of the slice set corresponding to the currently selected slice priority includes at least two neighbor cells, select the at least two neighbor cells according to the signal strength.

If the same priority combination corresponds to multiple supporting 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 intra-cell re-selection, but Cell1 only supports slice 2 (SST=2, SD=××), the base station needs to This field is added to the RRC release signaling, and SST=1 is set as the highest priority. The terminal performs cell intra-frequency reselection according to the priority, and preferentially reselection to the neighboring cell Cell0 corresponding to SST=1. If there are multiple corresponding cells for the first priority, the multiple cells are selected according to the signal strength. If the cell corresponding to the first priority is empty, the cell is selected 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. If the timer expires, 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, where the slice set corresponding to the first priority includes all slices corresponding to the slice types supported by the terminal;

a second priority, where the slice set corresponding to the second priority includes partial slices corresponding to the slice types supported by the terminal;

The third priority, where the slice set corresponding to the third priority does not include slices corresponding to the slice types supported by the terminal.

Correspondingly, performing intra-frequency reselection in the order of slice priorities according to the RRC release signaling, including:

Perform intra-frequency reselection in the slice set of the first priority; (if in the slice set of the first priority) If the slice set of the first priority is empty, perform intra-frequency reselection in the slice set of the second priority select;

If the slice set of the second priority is empty, the same-frequency reselection is performed in the slice set of the third priority.
