Method and system for accessing network
First Claim
1. A method for accessing a network, comprising:
- performing, by terminals belonging to a same group, random number synchronization;
when an arbitrary first terminal in the group initiates a first network access, monitoring the first network access of the first terminal by other terminals in the group, except the first terminal, according to a synchronized random number;
after monitoring that the first terminal accesses a network successfully, initiating a second network access by the other terminals in the group, except the first terminal, using radio resource control (RRC) connection uplink (UL) resources allocated to the group by the network,wherein the performing, by the terminals belonging to the same group, the random number synchronization comprises;
selecting a same pseudo random number generator according to a group ID and generating a same pseudo random number seed according to the group ID by the terminals in the same group;
selecting, by the terminals in the same group, a same downlink (DL) slot position as an input reference time point; and
determining, by the terminals in the same group, a random number according to the pseudo random number seed and the input reference time point.

Abstract
A method and system for accessing a network are disclosed in the present invention. The method includes that: terminals in a same group execute random number synchronization; when an arbitrary first terminal in the group initiates network access, terminals in the group except the first terminal monitor the access of the first terminal according to the synchronized random number; after monitoring that the first terminal accesses network successfully, the terminals in the group except the first terminal initiate network access by using Radio Resource Control (RRC) connection uplink resources which are allocated to the group by the network. The technical solution of the present invention can reduce the signaling overhead for establishing signaling connection and data bearing.

8. 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, wherein the terminals belonging to the same group establish the synchronized random number by performing a method comprising; selecting a same pseudo random number generator according to a group ID and generating a same pseudo random number seed according to the group ID by the terminals in the same group; selecting, by the terminals in the same group, a same downlink (DL) slot position as an input reference time point and determining, by the terminals in the same group, a random number according to the pseudo random number seed and the input reference time point. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A terminal, comprising:
-
a processor; and a non-transitory computer readable medium including computer-executable instructions that, when executed by the processor, facilitate; performing a random number synchronization by the terminal with other terminals belonging to a same group by; selecting a same pseudo random number generator according to a group ID, and generating a same pseudo random number seed according to the group ID by terminals in a same group; selecting a same downlink (DL) slot position as an input reference time point; and determining a random number according to the pseudo random number seed and the input reference time point so as to perform random number synchronization with the terminals belonging to the same group; monitoring, when an arbitrary first terminal in the group initiates a first network access, the first network access of the first terminal according to a synchronized random number; accessing, after a result that the first terminal accesses a network successfully is monitored, the network using radio resource control (RRC) connection uplink (UL) resources allocated to the group by the network. - View Dependent Claims (16, 17, 18)

19. A communication network element (NE), comprising:
-
a processor; and a non-transitory computer-readable medium including computer executable instructions that when executed by the processor, facilitate grouping terminals, wherein terminals belonging to a same group have a synchronized random number, and wherein the terminals belonging to the same group establish the synchronized random number by performing a method comprising; selecting a same pseudo random number generator according to a group ID and generating a same pseudo random number seed according to the group ID by the terminals in the same group; selecting, by the terminals in the same group, a same downlink (DL) slot position as an input reference time point; and determining, by the terminals in the same group, a random number according to the pseudo random number seed and the input reference time point; and a receiver configured to receive a first network access initiated by an arbitrary first terminal in the same 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. - View Dependent Claims (20, 21, 22)
