Abstract
The invention discloses a method and device for processing timer switching. The method comprises the steps of receiving a command used for indicating switching, conducting parameter reconfiguration, and starting a timer after parameter reconfiguration success. Through the method and device, at least one of the following problems, regulated in a relevant protocol, that timer duration backspacing cannot be realized after parameter reconfiguration fails caused by mishandling to the timer during the switching process and switching time is too long caused by mishandling to the timer is solved, and therefore the consistency with a current standard protocol is kept.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of switching timer processing method and device.
Background technology
Along with third generation partner program (3rd Generation Partnership Project, abbreviate 3GPP as) propelling of technology, the communications industry is to Long Term Evolution (Long-Term Evolution, abbreviating LTE as) commercialization of system accelerates to promote, the LTE technology is more and more accepted by people and support is held, and technical documentation and regulation are also perfect thereupon, still, along with increasing of the commercial scene of LTE system, practice will reflect in the agreement can't consider thorough aspect.Such problem will appear in handoff procedure.
Fig. 1 is the non-flow chart of competing handover success according to correlation technique, as shown in Figure 1, in handoff procedure, subscriber equipment (User Equipment, abbreviate UE as) at the switching command that receives source base station (S_eNB) transmission (for example, switch reallocation message) afterwards, UE starts T304 timer (what use in the present agreement is the T304 timer), UE uses the T304 duration value in the reallocation message, and, to PDCP (Packet Data Convergence Protocol, abbreviate PDCP as), Radio Link control (Radio Link Control, abbreviate RLC as), medium access control (MediaAccess Control abbreviates MAC as), each layer of PHY carries out reprovision.Under the reprovision case of successful, carry out the random access procedure of non-competing switching.After the handover success, stop the T304 timer, and send handoff completion message (for example, reprovision is finished message) to target BS (T_eNB).
Fig. 2 is the flow chart of failing according to the switching reprovision of correlation technique, and is different with Fig. 1, and as shown in Figure 2, after each layer carried out reprovision, the failure of one deck reprovision all can be recognized and understand this reprovision failure arbitrarily, thereby the rollback parameter is to the preceding state of reprovision.But, if shown in 2, in present agreement, to not stop the T304 timer after the failure of regulation reprovision, only illustrated that this time the reprovision parameter is unavailable.This can cause the generation of contradiction: since T304 switches that reallocation message will be opened and duration is entrained for switching reallocation message receiving, when reprovision is failed, can think that this reprovision parameter is unavailable and want the rollback parameter, and the T304 timer parameter has used and can't revise at this moment.
Summary of the invention

Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Fig. 3 is the flow chart according to the switching timer processing method of the embodiment of the invention, and as shown in Figure 1, this flow process comprises the steps:
Step S102 receives and is used to indicate the order of switching, the line parameter reprovision of going forward side by side;
Step S104 after parameter renegotiation is made into merit, starts timer.
In above-mentioned steps, the T304 timer is opened the moment pass backward, namely wait until after each layer reprovision is successfully and just open this timer.After so just guaranteeing the reprovision failure, can rollback T304 timer parameter, consistent with present agreement (being not need clearly to stipulate to stop T304 after the reprovision failure) yet yet.In addition, owing to after the reprovision success, carry out in the switching flow after the T304 timer begins, therefore, processing mode is compared with the processing mode of correlation technique, reduced the complexity when flow process is unusual, guarantee the hand-off process time simultaneously, reduce the probability of handoff failure, improved the network quality of operator.
In the above-mentioned steps, timer is used for timing is carried out in switching.For example, can behind timer expiry, determine this handoff failure; Again for example, can also after handover success, stop this timer.In the LTE system, this timer is the T304 timer.For other system, may be inconsistent with the LTE system though the title of timer is regularly carried out in switching,, if also there is identical problem, above-mentioned steps S102 and step S104 also can address this problem so, obtain identical technique effect.
In another preferred embodiment, if the failure of parameter reprovision (for example, one of at least configuration failure in PDCP layer parameter reprovision failure, the failure of rlc layer parameter reprovision, the failure of MAC layer parameter reprovision, the failure of PHY layer parameter reprovision), so, the parameter of can all reprovisions of rollback crossing, concurrent the upright flow process of reconstruction that the reprovision failure causes.
Preferably, the switching in the present embodiment can be the handoff procedure of minizone, also can be the handoff procedure in the residential quarter.For the handoff procedure in the residential quarter, switching command can adopt the step in the following preferred embodiment to send to subscriber equipment: subscriber equipment initiating updating of tracking area (Tracking Area Update, abbreviate TAU as) flow process, to carry out authentication mutual with network side, and core net is initiated the subscriber equipment initial context and revised request; The base station sends to be used to indicate and carries out the order that intra-cell is changed after receiving subscriber equipment initial context modification request.
