A method for exchanging common enhanced dedicated channel relative grant channel, common E-RGCH, information, comprising: receiving, by a first radio network controller, RNC, a common E-RGCH information message of a cell managed by a second radio network controller, RNC, from the second RNC, wherein the second RNC is adjacent to the first RNC, wherein the common E-RGCH information message is sent by the second RNC and comprises common E-RGCH configuration parameter information; characterized in that the method further comprises: receiving, by the first RNC, a radio resource control, RRC, connection establishment request sent by a user equipment, UE; establishing, by the first RNC, an RRC connection with the UE in a serving cell according to the RRC connection establishment request; determining (S 13), by the first RNC, a candidate common E-RGCH receiving neighboring cell set of the UE according to the common E-RGCH information message; and sending, by the first RNC, common E-RGCH configuration parameter information of each cell in the candidate common E-RGCH receiving neighboring cell set to the UE, wherein before receiving the common E-RGCH information message of the cell managed by the first RNC from the second RNC, wherein the common E-RGCH information message is sent by the second RNC, updating, by the first RNC, common E-RGCH information of the cell managed by the second RNC, wherein the updating common E-RGCH information of the cell managed by the second RNC comprises one of: changing, by the first RNC, the common E-RGCH information of the cell managed by the second RNC from Available to Unavailable, changing the common E-RGCH information from Unavailable to Available and changing a configuration parameter of a common E-RGCH. receiving, by a first radio network controller, RNC, a common E-RGCH information message of a cell managed by a second radio network controller, RNC, from the second RNC, wherein the second RNC is adjacent to the first RNC, wherein the common E-RGCH information message is sent by the second RNC and comprises common E-RGCH configuration parameter information; characterized in that the method further comprises: receiving, by the first RNC, a radio resource control, RRC, connection establishment request sent by a user equipment, UE; establishing, by the first RNC, an RRC connection with the UE in a serving cell according to the RRC connection establishment request; determining (S 13), by the first RNC, a candidate common E-RGCH receiving neighboring cell set of the UE according to the common E-RGCH information message; and sending, by the first RNC, common E-RGCH configuration parameter information of each cell in the candidate common E-RGCH receiving neighboring cell set to the UE, wherein before receiving the common E-RGCH information message of the cell managed by the first RNC from the second RNC, wherein the common E-RGCH information message is sent by the second RNC, receiving, by the first RNC, a radio resource control, RRC, connection establishment request sent by a user equipment, UE; establishing, by the first RNC, an RRC connection with the UE in a serving cell according to the RRC connection establishment request; determining (S 13), by the first RNC, a candidate common E-RGCH receiving neighboring cell set of the UE according to the common E-RGCH information message; and sending, by the first RNC, common E-RGCH configuration parameter information of each cell in the candidate common E-RGCH receiving neighboring cell set to the UE, wherein before receiving the common E-RGCH information message of the cell managed by the first RNC from the second RNC, wherein the common E-RGCH information message is sent by the second RNC, updating, by the first RNC, common E-RGCH information of the cell managed by the second RNC, wherein the updating common E-RGCH information of the cell managed by the second RNC comprises one of: changing, by the first RNC, the common E-RGCH information of the cell managed by the second RNC from Available to Unavailable, changing the common E-RGCH information from Unavailable to Available and changing a configuration parameter of a common E-RGCH. changing, by the first RNC, the common E-RGCH information of the cell managed by the second RNC from Available to Unavailable, changing the common E-RGCH information from Unavailable to Available and changing a configuration parameter of a common E-RGCH.
