Description
Technical field
The present embodiments relate to the technical field of communication, more particularly to a kind of method and device for accessing network.
Background technology
During MESH networkings, newly-built node needs, by complete access procedure, can just be included into existing network.
In access procedure, including newly-built node reads each broadcast message in net node of MESH network；Then newly-built node selection is closed
Suitable assistance node sends access request；Node is assisted to determine whether to receive newly-built node and pass through according to information such as the qualities of reception
Broadcast is handed down to newly-built node；Newly-built node completes access procedure after being confirmed the message being successfully accessed, and right in superframes
Answer position to send its broadcast message, intercepted for other nodes in network, and it is newly-built to assist node quickly can correctly parse
The broadcast message that node is sent.
In common access procedure, such as in third generation partner program (The 3rd Generation
Partnership Project, 3GPP) in Long Term Evolution (Long Term Evolution, LTE), user equipment (UE) receives
Side is adjusted by automatic growth control (automatic gain control, AGC) and reads Physical Broadcast Channel (Physical
Broadcast Channel, PBCH), then UE sends Mgs information by power control and establishes wireless heterogeneous networks (Radio with base station
Resource Control, RRC) connection completion access procedure.In LTE access procedures access is completed using AGC and Power Control
Process, ensure that UE and base station can proper communications.The reason for this access way can not be used in MESH network completely has two
Point：First point, due to newly-built node received signal power excursion 10dbm~-110dbm, transformation range is larger, and one
Needing to parse the PBCH information of many nodes in superframe, therefore use traditional LTE UE sides AGC processes, convergence time is slow, and
It is not easy to find out the PBCH information of multiple nodes；Second point, relative to base station eNodeB in LTE, UE belongs to subordinate status, sends
It is power-controlled, and MESH nodes belong to equality node, newly-built node sends broadcast and business completely can be according to rated power
Send, can not so refer to LTE UE sides Power Control and carry out.
