Method, device and system for wireless broadband communications
First Claim
1. A method for wireless broadband communications, the method comprising:
- receiving, by a small cell, a dedicated synchronization signal Preamble sent through a first message by a user equipment UE in an idle state, wherein the dedicated Preamble is allocated when the UE accesses a network for the first time;
querying, by the small cell according to the dedicated Preamble, whether a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE are/is stored;
if stored, replying, by the small cell in a second message to the UE, indication information that the SRB 1 and/or the SRB2 between the small cell and the UE do/does not need to be re-established or modified;
receiving an uplink radio resource control RRC message sent through a dedicated control channel by the UE; and
before the receiving, by a small cell, a dedicated synchronization signal Preamble sent through a first message by a UE in an idle state, sending, by the small cell to the UE, the dedicated Preamble, an SRB, logical channel resource configuration, transmission channel resource configuration and physical channel resource configuration allocated by the network when the UE accesses the network through the small cell for the first time, and storing the dedicated Preamble, the SRB, the logical channel resource configuration, the transmission channel resource configuration and the physical channel resource configuration that are sent.

Abstract
A small cell receives a dedicated synchronization signal Preamble sent through a first message by a user equipment UE in an idle state. The dedicated Preamble is allocated when the UE accesses a network for the first time. The small cell according to the dedicated Preamble queries whether a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE are/is stored. If stored, the small cell replies in a second message to the UE that indication information that the SRB 1 and/or the SRB2 between the small cell and the UE do/does not need to be re-established or modified. An uplink radio resource control RRC message sent through a dedicated control channel DCCH by the UE is received.

7. A method for wireless broadband communications, the method comprising:
-
sending, by a UE, a dedicated Preamble through a first message when the UE is in an idle state, wherein the dedicated Preamble is allocated when the UE accesses a network for the first time; receiving, by the UE, indication information, sent by a small cell in a second message, that a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE do/does not need to be re-established or modified, and sending, by the UE, an uplink RRC message through a dedicated control channel; receiving, by the UE, the dedicated Preamble, an SRB, logical channel resource configuration, transmission channel resource configuration and physical channel resource configuration allocated by the network and sent by the small cell when the UE accesses the network through the small cell for the first time and storing the dedicated Preamble, the SRB, the logical channel resource configuration, the transmission channel resource configuration and the physical channel resource configuration that are received. - View Dependent Claims (8, 9)

10. A small cell for wireless broadband communications, comprising:
-
a transceiver module, configured to receive a dedicated Preamble sent through a first message by a UE in an idle state, wherein the dedicated Preamble is allocated when the UE accesses a network for the first time, configured to send a second message to the UE after a processing module determines that a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE are/is stored, and configured to receive an uplink radio resource control RRC message sent through a dedicated control channel by the UE after the second message is sent; and the processing module, configured to query whether the SRB 1 and/or the SRB2 of the UE are/is stored according to the dedicated Preamble received by the transceiver module, and configured to carry indication information, in the second message sent by the transceiver module, that the SRB 1 and/or the SRB2 between the small cell and the UE do/does not need to be re-established or modified after it is determined that the SRB 1 and/or the SRB2 of the UE are/is stored, wherein the transceiver module is further configured to send, to the UE, the dedicated Preamble, an SRB, logical channel resource configuration, transmission channel resource configuration and physical channel resource configuration allocated by the network when the UE accesses the network through the small cell for the first time, and wherein the small cell further comprises a mapping table storing module, configured to store the dedicated Preamble, the SRB, the logical channel resource configuration, the transmission channel resource configuration and the physical channel resource configuration sent by the transceiver module. - View Dependent Claims (11, 12, 13, 14)
