A cell access method applied to user equipment, the method comprises: acquiring an identifier of at least one cell of one or more cells, wherein the identifier of the at least one cell is a physical cell identifier, PCI, configured by an operator through an operation administration and maintenance, OAM, system, and a PCI of a high-speed dedicated network cell is different from a PCI of a cell in a public network; determining the PCI of the at least one cell matching a pre-stored identifier, and further determining the at least one cell as the high-speed dedicated network cell; and in response to determining that the at least one cell is a high-speed dedicated network cell, determining whether or not to access the high-speed dedicated network cell according to a current mobility state of the user equipment; wherein the step of determining whether or not to access the high-speed dedicated network cell according to the current mobility state of the user equipment comprises: recording information of a neighbor cell of a cell where the user equipment resides; determining an amount of the information, recorded in unit time, of the neighbor cell; and determining a mobility state of the user equipment according to a relationship between the amount and one or more preset amounts as well as association information of the relationship with the mobility state; wherein the one or more preset amounts comprise a first amount and a second amount, and the second amount is greater than or equal to the first amount; and wherein the step of determining the mobility state of the user equipment according to the relationship between the amount and the one or more preset amounts as well as the association information of the relationship with the mobility state comprises: in response to the amount being less than or equal to the first amount, determining that the user equipment is in a low-speed mobility state. acquiring an identifier of at least one cell of one or more cells, wherein the identifier of the at least one cell is a physical cell identifier, PCI, configured by an operator through an operation administration and maintenance, OAM, system, and a PCI of a high-speed dedicated network cell is different from a PCI of a cell in a public network; determining the PCI of the at least one cell matching a pre-stored identifier, and further determining the at least one cell as the high-speed dedicated network cell; and in response to determining that the at least one cell is a high-speed dedicated network cell, determining whether or not to access the high-speed dedicated network cell according to a current mobility state of the user equipment; recording information of a neighbor cell of a cell where the user equipment resides; determining an amount of the information, recorded in unit time, of the neighbor cell; and determining a mobility state of the user equipment according to a relationship between the amount and one or more preset amounts as well as association information of the relationship with the mobility state; wherein the one or more preset amounts comprise a first amount and a second amount, and the second amount is greater than or equal to the first amount; and wherein the step of determining the mobility state of the user equipment according to the relationship between the amount and the one or more preset amounts as well as the association information of the relationship with the mobility state comprises: in response to the amount being less than or equal to the first amount, determining that the user equipment is in a low-speed mobility state.
