Preferred embodiment two
Present embodiment provides a kind of method of terminal connecting system, and in the present embodiment, terminal has begun random access procedure before receiving the system message update indication, and this embodiment comprises the steps that S2 is to step S14.
Step S2: terminal 1 normally resides in the residential quarter, residential quarter cyclical transmission system information, and terminal 1 has received all system informations.
Step S4: terminal 1 prepares to initiate access procedure, and the reason of this initiation access includes but not limited to: operation layer is initiated a business, is initiated a signaling procedure etc.
Step S6: terminal 1 begins to carry out random access procedure according to the access parameter in the current system information.
Preferably, the system parameters that is used for access procedure comprises: access control parameter (AC-barringinfo, access grade prohibition information), accidental access channel parameter, random access code information, power information, access maximum reattempt times, accidental access response window information, information number of retransmissions etc. at random.
Step S8: when terminal 1 was prepared to access at random, it is heavier that system detects present load, needs to revise the access that access information limits a part of user, begins executive system information updating process in internal system.
Particularly, system need to notify custom system information to change; Upgrade indication by the system information of having put in the paging process generally speaking, terminal receives that paging signaling discovery system information renewal wherein is designated as ture, just knows that system information will change.
In the present embodiment, need the two type systematic information of distinguishing, the modification of Class1 is based on the modification cycle, and the modification of type 2 is based on the repetition period; The renewal indication of two type systematic information is independently, and that is to say has independently Class1 system information renewal indication and type 2 system informations to upgrade indication in the paging signaling.
For example: if the system information content update of Class1, then system sends first the paging signaling and Class1 system information renewal indication has wherein been put, and when the next system information modification cycle arrived, system sent the Class1 system information after upgrading.
If the system information content update of type 2, then system sends first the paging signaling and type 2 system informations renewal indication has wherein been put, and when the next system information repetition period arrived, system sent type 2 system informations after upgrading.
General System information all belongs to Class1, for type 2 system informations, the system information of ETWS (address tsunami) and CMAS (the commercial warning) purposes is arranged at present; Access control parameter for the M2M type terminals of enormous amount also can adopt the mode of type 2 to upgrade, can reduce terminal and obtain the time delay of new access parameter, avoid a large number of users connecting system of swarming at short notice to cause the situation of systemic breakdown to occur.
Particularly, one " EAB information is revised indication " is set in the Paging signaling, EAB (control of extended access barring expansion access barred) is a kind of connection control method for the M2M type terminals.The renewal of EAB information can be upgraded according to the system information modification cycle (belonging to system information type 1) or upgrade (belonging to system information type 2) according to the system information repetition period, need one of agreement dual mode, terminal can be known the update mode of EAB information in advance like this.In the present embodiment, EAB information adopts the mode of type 2.
Terminal 1 is being carried out random access procedure, arranges according to state before because current access parameter is system, do not met the situation of current system or collision occurred, so the at random access attempts that terminal 1 is carried out does not also have success.
In the present embodiment, access attempts does not refer to successfully that also terminal finally successfully do not set up RRC and connect at random, that is to say that terminal ends all to belong at random access attempts unsuccessfully successfully setting up all before being connected of RRC with system.In existing random access procedure, be to allow terminal to carry out repeatedly at random access attempts.
Step S10: terminal 1 also can be monitored paging when carrying out random access procedure, upgrades indication according to the system information in the call signaling, and terminal 1 can know that system will send the system information of renewal.
Step S12: terminal 1 will determine to end current random access procedure, and the executive system information updating, continue to carry out random access procedure according to new system information content again after receiving new system information.
Stop can comprise following situation in the concrete at random access, but is not limited to following situation, and the below exemplifies explanation.
Situation one: if UE is carrying out ACB (Access class barring, access grade is forbidden) judgement, and forbid that timer is in running status.
Situation two: if do not receive the RAR (accidental access response) that reply the base station behind the preamble code that UE sends, plan to retransmit preamble.
Situation three: if UE does not also send msg3, UE ends random access procedure so, reads SIB to obtain new EAB parameter.
Situation four: if UE has sent msg3, but do not receive the Msg4 of base station feedback in the receiver window of Msg4, the ID that comprises among the Msg4 that perhaps receives and the ID of oneself are not inconsistent.
Step S14: terminal 1 is indicated according to the type in the call signaling, if what put is that the Class1 system information is upgraded indication, then terminal 1 is according to the system information modification cycle, when the next one modification cycle arrives, read new system information, then carry out random access procedure according to the content of new Class1 system information.
If what put is that type 2 system informations are upgraded indication, then terminal 1 reads new type 2 system informations according to the system information repetition period when the next repetition period arrives, and then carries out random access procedure according to the content of new type 2 system informations.
EAB adopts the mode of type 2 in the present embodiment, terminal 1 receives that the paging signaling finds that wherein " EAB information is revised indication " put afterwards, according to the EAB information of system information repetition period after the repetition period of next EAB place system information receives renewal constantly.
After terminal 1 is received EAB information after the renewal, again according to the parameter in the EAB information, carry out random access procedure, concrete comprises, if with own relevant EAB parameter change has occured, then whether terminal 1 allows access according to new EAB parameter judgement, and carries out process subsequently; If do not change with own relevant EAB parameter, terminal 1 can be restarted random access procedure or be continued to carry out random access procedure from the point of ending before, be that terminal has sent twice preamble code (lead code) but do not receive the RAR response such as stop in before, this moment, terminal can continue to send for the third time preamble code.
Fig. 6 is the flow chart one of according to the preferred embodiment of the invention access processing method, and as shown in Figure 6, the method comprises the steps that S602 is to step S616.
Step S602: the base station is the sending system broadcast periodically.
Step S604: system occurs congested, triggers the update system broadcast.
Step S606: terminal uses old access parameter to access.
Step S608: the change of Paging notifying system message is used in the base station.
Step S610: terminal knows that system message will upgrade.
Step S612: the base station issues the system broadcast message of renewal.
Step S614: terminal receives new system message.
Step S616: terminal uses new access parameter to access.
Preferred embodiment three
Present embodiment provides a kind of method of terminal connecting system, and in the present embodiment, terminal just begins random access procedure after receiving system message update indication, and the method for present embodiment comprises the steps that S20 is to step S80:
Step S20: terminal 2 normally resides in the residential quarter, residential quarter cyclical transmission system information, and terminal 2 has received all system informations.
Step S40: in system's running, it is heavier that system detects present load, needs to revise the access that access information limits a part of user, begins executive system information updating process in internal system.
Preferably, system need to notify custom system information to change.Upgrade indication by the system information of having put in the paging process generally speaking, terminal receives that paging signaling discovery system information renewal wherein is designated as ture, just knows that system information will change.
Distinguish two type systematic information in the present embodiment, the modification of Class1 is based on the modification cycle, and the modification of type 2 is based on the repetition period; The renewal indication of two type systematic information is independently, and that is to say has independently Class1 system information renewal indication and type 2 system informations to upgrade indication in the paging signaling.
For example: if the system information content update of Class1, then system sends first the paging signaling and Class1 system information renewal indication has wherein been put, and when the next system information modification cycle arrived, system sent the Class1 system information after upgrading.
If the system information content update of type 2, then system sends first the paging signaling and type 2 system informations renewal indication has wherein been put, and when the next system information repetition period arrived, system sent type 2 system informations after upgrading.
General System information all belongs to Class1, for type 2 system informations, ETWS (address tsunami) and CMAS (the commercial warning) purposes is arranged at present; Access control parameter for the M2M type terminals of enormous amount also can adopt the mode of type 2 to upgrade, can reduce terminal and obtain the time delay of new access parameter, avoid a large number of users connecting system of swarming at short notice to cause the situation of systemic breakdown to occur.
Preferred embodiment one " EAB information revise indication " is set in the Paging signaling as one, EAB (control of extended access barring expansion access barred) is a kind of connection control method for the M2M type terminals.
The renewal of EAB information can be upgraded according to the system information modification cycle (belonging to system information type 1) or upgrade (belonging to system information type 2) according to the system information repetition period, but need one of agreement dual mode, terminal can be known the update mode of EAB information in advance like this.In the present embodiment, EAB information adopts the mode of type 2.
Step S60: terminal 2 is periodically monitored paging, upgrades indication according to the system information in the call signaling, and terminal 2 can know that system will send the system information of renewal.
Step S80: terminal 2 is indicated according to the type in the call signaling, if what put is that the Class1 system information is upgraded indication, then terminal 2 is according to the system information modification cycle, when the next one modification cycle arrives, read new system information, then carry out random access procedure according to the content of new Class1 system information.
For example: if what put is that type 2 system informations are upgraded indication, then terminal 2 is according to the system information repetition period, when the next repetition period arrives, read new type 2 system informations, then carry out random access procedure according to the content of new type 2 system informations.
Again for example: just when terminal 2 receives the Paging signaling and knows that system will send the system information of renewal, terminal 2 prepares to initiate access procedure, and the reason of this initiation access includes but not limited to: operation layer is initiated a business, is initiated a signaling procedure etc.
At this moment, terminal 2 temporary respite random access procedures, but first executive system information updating process begins to carry out random access procedure according to new system information content again after receiving new system information.
Preferably, the system parameters that is used for access procedure comprises: access control parameter (AC-barringinfo, access grade prohibition information), accidental access channel parameter, random access code information, power information, access maximum reattempt times, accidental access response window information, information number of retransmissions etc. at random.
