Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to an indication method, device and equipment for accessing a network. BACKGROUND

[0002] In a New Radio (NR) network, a RedCap (Reduced Capability) terminal with reduced communication capability is introduced. In the network, there can be a cell that does not allow RedCap UE (User Equipment) to access, and there can also be a cell that allows part of RedCap UE (such as 1Rx or 2Rx) to access. Whether to allow RedCap UE to access or allow part of RedCap UE (such as 1Rx or 2Rx) to access can be determined according to the actual network deployment situation, and an explicit indication is given. At present, at least the following problems exist when RedCap UE accesses the network:

[0003] I. When RedCap UE performs cell reselection, it needs to scan the cells of each NR frequency point according to its own capability, and can only know whether the current cell allows RedCap UE to access after reading the SIB1 of the cell. In this way, the time length of RedCap UE cell reselection is prolonged, and unnecessary waste of RedCap UE power consumption is caused.

[0004] II. RedCap UE cannot obtain more accurate neighbor cell information, and the flexibility of RedCap UE network deployment is limited, which will cause certain impact on the user experience and network performance of RedCap UE. SUMMARY

[0050] like Figure 1 As shown, an embodiment of the present invention provides a method for indicating network access, applied to a network-side device, the method comprising:

[0051] Step 11: Send a first indication message for accessing the network and / or a second indication message for whether the neighboring cell allows the simplified capability terminal to access the network to the simplified capability terminal. The first indication message is used to instruct the simplified capability terminal to reselect a target neighboring cell with the same priority or a lower priority for reselecting neighboring cells in different frequencies.

[0052] In this embodiment, the network-side device can be a base station. The system broadcast information or other information in the base station is supplemented with first indication information for accessing the network and / or second indication information on whether the neighboring cell allows the simplified capability terminal to access the network. This information is then sent to the terminal, instructing the terminal to reselect to a target neighboring cell of equal priority or with a lower reselection priority in a different frequency neighboring cell. By instructing the terminal to make a selection through specific indication information, the time for the terminal to reselect a cell is reduced, and the terminal power consumption is saved.

[0053] In an optional embodiment of the present invention, the first indication information of the access network is described as follows: the first indication information of the access network includes: first target indication information and / or at least one co-channel interference threshold value; the first target indication information is used to indicate whether the network-side device allows the simplified capability terminal to preferentially reselect to a target neighbor cell with lower reselection priority among the same priority or different frequency neighbor cells in the case of high priority frequency points or co-channel interference; the co-channel interference threshold value is used to define the corresponding interference threshold value on the co-channel frequency point and / or one or more different frequency points.

[0067] In an optional embodiment of the present application, for inter-frequency cell reselection, the sixth preset field of the inter-frequency neighbor cell list information in the system information SIB4 carries the second indication information or

[0068] The seventh preset field of the inter-frequency neighbor cell information in the system information SIB4 carries the second indication information; or

[0069] The eighth preset field of the neighbor cell white list of the inter-frequency neighbor cell list in the system information SIB4 carries the second indication information.

[0070] In this embodiment, the second indication information dedicated to the simplified capability terminal is added in the inter-frequency neighbor cell list, including but not limited to: inter-frequency frequency point and / or cell ID, second target indication information allowing 1Rx and / or 2Rx simplified capability terminal to access, cell reselection parameter dedicated to 1Rx and / or 2Rx simplified capability terminal, such as at least one same frequency interference threshold value mentioned above, and inter-frequency neighbor cell reselection priority dedicated to the simplified capability terminal;

[0074] In this embodiment, the general parameter of the simplified capability terminal cell reselection is added in the system information SIB2, including but not limited to: the threshold value for the 1Rx and / or 2Rx simplified capability terminal to start the intra-frequency neighbor cell measurement, and / or the threshold value for the 1Rx and / or 2Rx simplified capability terminal to start the inter-frequency neighbor cell measurement of the same priority and / or low priority, and / or the threshold value for the 1Rx and / or 2Rx simplified capability terminal to perform the intra-frequency and / or inter-frequency neighbor cell reselection of the same priority and / or low priority.

[0075] In the above embodiments of the present application, the simplified capability terminal can obtain the related information about whether the intra-frequency / inter-frequency neighbor cell allows the simplified capability terminal to access, and the 1Rx / 2Rx simplified capability terminal only detects the intra-frequency / inter-frequency neighbor cell allowing the simplified capability terminal to access when performing the cell reselection, thereby avoiding detecting the neighbor cell not allowing the simplified capability terminal to access, avoiding the long cell reselection time, and effectively saving the terminal power consumption.

[0077] The 1Rx / 2Rx simplified capability terminal is allowed to reselect to the inter-frequency neighbor cell of the same priority / low priority when the intra-frequency interference is serious, so that the strong signal of the cell not allowing the simplified capability terminal can be avoided to interfere with the intra-frequency of the terminal, the particularity of the communication capability of the 1Rx / 2Rx simplified capability terminal is fully considered, the performance of the 1Rx / 2Rx simplified capability terminal is effectively guaranteed, and the influence on the existing cell reselection neighbor cell information and parameter of the non-simplified capability terminal can be effectively avoided.

[0081] The same-frequency interference threshold value is used for defining a corresponding interference threshold value on a same-frequency frequency point and / or at least one inter-frequency frequency point.

[0082] Further, the method for accessing the network further comprises the following steps:
