Method and apparatus for selecting and accessing network, and computer storage medium

1. A method for selecting and accessing a network, comprising:

broadcasting, by a base station, access parameter information, wherein the access parameter information comprises an offset of a coverage enhancement (CE) level reference signal received power (RSRP) threshold of a cell relative to a minimum reception level threshold for decision of cell residence, and is used for enabling a user equipment (UE) without authorization of CE to determine whether the UE is configured to use a network resource of a target cell, and

wherein the UE is configured to:

in response to a radio quality RSRP value of the cell being lower than the CE level RSRP threshold of the cell, perform a step of excluding the cell or degrading a cell selection priority level of the cell to a lowest level, and

make a determination to initiate a physical random access channel (PRACH) based on whether the UE is configured to use the network resource of the target cell.

12. The method of claim 8 , wherein the authorization of CE is an authorization of the overall CE in a case where the access parameter information comprises the offset of the CE level RSRP threshold corresponding to the CE level 0 relative to the minimum reception level threshold for the decision of cell residence.

13. The method of claim 12 , wherein the authorization of the overall CE comprises controlling whether the UE is configured to use a resource of coverage enhancements (CEs).

14. The method of claim 8 , wherein the authorization of CE is an authorization of the overall CE in a case where the access parameter information comprises the offset of the minimum reception level threshold of the cell without authorization of CE relative to the minimum reception level threshold of the cell.

15. An apparatus for selecting and accessing a network, comprising:

a processor; and

a memory with instructions thereon, wherein the instructions upon execution by the processor cause the processor to:

wherein the UE is configured to:

in response to a radio quality RSRP value of the cell being lower than the CE level RSRP threshold of the cell, perform a step of exclude the cell or degrade a cell selection priority level of the cell to a lowest level, and

make a determination to initiate a physical random access channel (PRACH) based on whether the UE is configured to use the network resource of the target cell.

16. The apparatus of claim 15 , wherein the access parameter information further comprises an offset of the minimum reception level threshold of the cell without authorization of CE relative to the minimum reception level threshold of the cell.
