Description
Technical field
The present invention relates to the communications field, particularly, relate to a kind of Long Term Evolution (Long-Term Evolution, abbreviate LTE as) control method and the device of interim Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Temporary Cell Radio Network Temporary Identifier abbreviates Temporary C-RNTI or Temp C-RNTI as) in the system.
Background technology
Random access procedure occurs between subscriber equipment (User Equipment abbreviates UE as) and the wireless access network (Radio Access Network abbreviates RAN as), and the scene of wireless connections is not also set up in the sub-district that is used for UE and access soon.Random access procedure can include the random access procedure and the conflict free random access procedure of conflict.
Fig. 1 is the schematic diagram that the LTE random access procedure of conflict is arranged in the correlation technique, in four interacting messages of the random access procedure shown in Fig. 1, message (Msg) 1 and Msg2 are by medium access control (Media Access Control, abbreviating MAC as) entity finishes, Msg3 and Msg4 are by Radio Resource control (Radio Resource Control, abbreviating RRC as) entity finishes, and as shown in Figure 1, the random access procedure that conflict is arranged between UE and the RAN is as follows:
Step S102, the MAC entity of UE side is at Random Access Channel (Random AccessChannel, abbreviate RACH as) go up to enode (Evolved Node B, abbreviating eNB as) the MAC entity of side sends Msg1, wherein, Msg1 carries effectively Access Preamble (Random Access Preamble) at random and corresponding route district Radio Network Temporary Identifier (Routing Area Radio Network Temporary Identifier abbreviates RA-RNTI as), time calibration information;
Step S 104, after the MAC entity of eNB side RAN correspondence receives Msg1, be UE distribution T emp C-RNTI, and according to behind the Access Preamble at random and time calibration information creating accidental access response Msg2, then, go up to the MAC of UE side entity transmission Msg2 at downlink sharied signal channel (Down LinkShared Channel abbreviates DLSCH as), and use RA-RNTI that UE is carried out addressing.Wherein, the up link (Up Link abbreviates UL as) that carries UE in the accidental access response message is authorized and Temp C-RNTI value etc.;
Step S106, the MAC entity of UE side receives this accidental access response and obtains uplink authorization, will insert the RRC entity of successfully indication notice UE side at random, then, the RRC solid tissue upstream data message Msg3 of UE side, and constantly send this message to the RRC of eNB side entity at uplink authorization;
Step S 108, after the RRC entity of eNB side receives the Msg3 that UE sends, returning conflict and solving response Msg4.For initial access or Radio Link Failure, use Temp C-RNTI that UE is carried out addressing; For switching or the scene of other UE under RRC_CONNECT, use formal C-RNTI that UE is carried out addressing.
Fig. 2 is the schematic diagram of the conflict free LTE random access procedure of correlation technique, in three interacting messages of random access procedure shown in Figure 2, Msg5 belongs to rrc layer message or MAC layer message, Msg6 and Msg7 belong to the accidental access response of MAC layer, except the source of the Access Preamble at random difference of Msg6, the process basically identical of Msg1 among handling process and Fig. 1 and Msg2.As shown in Figure 2, the conflict free detailed process that inserts at random of UE and RAN is as follows:
Step S202, the RRC entity or the MAC entity of eNB side send Msg5 to UE, wherein, carry special-purpose Access Preamble (RA-RNTI) among the Msg5;
Step S204, UE use the RA-RNTI that issues among the Msg5 to send to eNB and insert request Msg6 at random;
Step S206 after the eNB of RAN side receives Msg6, issues accidental access response Msg7, by RA-RNTI addressing UE.
From above two kinds of random processes as can be seen: during not having the conflict random access procedure, in step S202, no matter be rrc layer signaling or MAC layer signaling, all can with RA-RNTI and at random Access Preamble inform UE.Step S204 and step S206 also be by RA-RNTI and at random Access Preamble carry out addressing, identical with step S102 with step S104.Then, then carry out addressing communication between UE and the wireless access network by all known C-RNTI of both sides.Therefore, do not insert situation at random for there being conflict, Msg7 does not need the C-RNTI to UE distribution T emp.
Yet, have the conflict random access procedure in, step S102 and step S104 by RA-RNTI and at random Access Preamble carry out addressing, belong to MAC layer process.Step S106 and step S108 belong to the interacting message of rrc layer, might carry out addressing by Temp C-RNTI, also might pass through the C-RNTI addressing.When the RRC entity is only received Msg3, could handle according to the information that Msg3 carries.But, in step S102 and step S104 process, having distributed Temp C-RNTI, MAC at that time can not judge whether this UE exists C-RNTI.
Therefore, the MAC layer does not have a kind of effective treatment mechanism to guarantee effective control of Temp C-RNTI after having distributed Temp C-RNTI.
