Method and system for accessing network

A method for accessing a network, comprising:

• grouping terminals, wherein terminals belonging to a same group have a synchronized random number;
• receiving a first network access initiated by an arbitrary first terminal in the group;
• after the first terminal successfully accesses the network, allocating radio resource control (RRC) connection uplink (UL) resources to the terminals of the group the first terminal belongs to;
• and
• receiving a second network access initiated by other terminals in the group, except the first terminal, using the RRC connection UL resources allocated to the group by the network after monitoring that the first terminal accesses network successfully.

A communication network element (NE), comprising:

• a processor configured to group terminals, wherein terminals belonging to a same group have a synchronized random number;
• and
• a receiver configured to receive a first network access initiated by an arbitrary first terminal in the group;
• wherein the processor is further configured to allocate radio resource control (RRC) connection uplink (UL) resources to all the terminals of the group the first terminal belongs to after the first terminal successfully accesses the network;
• and
• the receiver is further configured to receive a second network access initiated by other terminals in the group, except the first terminal, using the RRC connection UL resources allocated to the group by the network after a result that the first terminal accesses successfully network is monitored.
