Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Before introducing the specific embodiment of the application, it is necessary first to which explanation, user equipment and network side lead to
Letter can be divided into two stages, first is that access phase, second is that the traffic communication stage.It can be seen that only user equipment correctly connects
Enter to network, just makes it possible the communication of user equipment and network side.For access phase, user equipment is first main random
It accesses on channel and sends random access preamble (Random Access Preamble, referred to as are as follows: RAP), this is equivalent to one and strikes
The movement of door, what user equipment carried out is the power control of open loop.That is, user equipment can send more than one RAP, just originate
Sending power is usually a kind of trial, and power is smaller, sees whether access network equipment can receive, next if do not received
The transmission power of a RAP just will increase a step-length, it is known that power is sufficiently strong, and access network equipment can receive user equipment
Signal.In RAP include two information, preamble signature (Preamble Signature) and preamble scrambling codes, network side according to
Preamble signature and preamble scrambling codes and the access slot at place are come to distinguish the RAP be which user sends.Access network equipment receives
After the RAP sent to user equipment, pass through AICH Acquisition Indication Channel (Acquisition Indication Channel, abbreviation
Are as follows: AICH) notifying user equipment can continue to send specific access request message.Capture on AICH indicates information
(Acquisition Indication, referred to as are as follows: AI) and Physical Random Access Channel (Physical Random Access
Channel, referred to as are as follows: PRACH) signature it is corresponding.User equipment sends access information on prach.Access network equipment connects
After receiving the access information that user equipment is sent on prach, Dedicated Physical Control Channel is distributed to user equipment
(Dedicated Physical Control Channel, referred to as are as follows: DPCCH) or Dedicated Physical Data Channel (Dedicated
Dedicated channels, and notifying user equipment, and then the user equipment such as Physical Data Channel, referred to as are as follows: DPDCH) can be with
It goes to access network equipment and distributes to and carry out registration or location updating etc. in the dedicated channel of oneself.
Embodiment one
Fig. 1 be the embodiment of the present invention one provide Poewr control method flow chart, this method be mainly used for it is leading just originate
The control of power is sent, as shown in Figure 1, this method comprises:
