The method includes: determining, by a user equipment (UE), a high speed downlink shared channel (HS-DSCH) physical layer category for memory allocation according to a first network configuration sent by a first network device; using the total number of soft channel bits corresponding to the determined HS-DSCH physical layer category as a total allocated memory size of a soft memory buffer, dividing the total allocated memory size of the soft memory buffer by the total number of serving or secondary serving HS-DSCH cells corresponding to the determined HS-DSCH physical layer category, and determining a soft memory buffer size of each HS-DSCH transmission channel; and allocating the soft memory buffer size of each HS-DSCH transmission channel among the HARQ processes in the first network configuration of the corresponding HS-DSCH transmission channel.
Abstract:
The present invention discloses a method, a network device, and a user equipment for controlling access to a core network. The method includes: determining that a change occurs in access control information for controlling a user equipment to access a core network; and sending radio resource control signaling to the user equipment through a dedicated control channel, where the radio resource control signaling is used to notify the user equipment that a change occurs in the access control information, so that the user equipment updates the access control information. Therefore, a load of a core network node can be effectively controlled, and system performance is improved.
Abstract:
Embodiments of the present application provide a method for determining a transmission time interval, a base station, and a radio network controller. A base station receives uplink data sent from a user equipment in an idle state or a cell forward access channel state on an enhanced dedicated transmission channel. The base station determines a transmission time interval (TTI) used by the user equipment for sending the uplink data, and sends the uplink data and a transmission time interval indicator in an enhanced dedicated transmission channel data frame to a radio network controller. The radio network controller acquires the TTI, thereby ensuring that the radio network controller selects and configures an appropriate TTI for the user equipment when the user equipment transits from the Cell_FACH state to the Cell_DCH state.

The present invention is capable of saving network resources, increasing the number of access users and reducing the interference therebetween.
Abstract:
A radio resource control (RRC) connection resume method includes receiving, by a first network device, an RRC connection resume request message from a terminal device. The RRC connection resume request message is used to request to resume an RRC connection of the terminal device. The method also includes sending a first message to a second network device. The first message includes auxiliary information. The auxiliary information includes at least one of information used by the terminal device to perform redirection or information used by the terminal device to perform cell reselection, or the auxiliary information indicates that the first network device cannot respond to the RRC connection resume request message of the terminal device. The method further includes receiving an RRC release message from the second network device. The method additionally includes sending the RRC release message to the terminal device.
