Abstract
The invention discloses a wireless resources control link request message processing method, making the user connection rate higher. And its character: by judging if there is user equipment unique identification in UTRAN-side maintained user equipment sequence, consistent with that in the wireless resources control link request message and determines whether the request is sent for the first time or repeatedly, thus avoiding repeated allocation of network-side resources to the user equipment. In addition, UTRAN side responds to repeatedly-received wireless resources control link request message and sends wireless resources control link building message many times, avoiding the message from being sent in non-confirm mode and being lost, increasing the possibility of user equipment receiving accurately the control link building message and thus increasing the user connection rate.
Description
Technical field
The present invention relates to the resource allocation methods in the communication system, particularly the processing method of wireless resource control connection request message.
Background technology
According to Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, abbreviation " WCDMA ") one of 3GPP 25 serial protocols 331 V3.7.0 (2001-06) agreement is to the explanation of Radio Resource control flow, as shown in Figure 1, as subscriber equipment (User Equipment, be called for short " UE ") to universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio AccessNetwork, be called for short " UTRAN ") transmission Radio Resource control (Radio Resource Control, be called for short " RRC ") during connection request message, it is 1 that counter V300 is set, and starts predefined timer T300.After this, if receiving from the RRC connection of UTRAN, UE do not set up message, and timer T300 is overtime, in this case, smaller or equal to predefined variable N300, then UE is again at Random Access Channel (Random Access CHannel as if above-mentioned counter V300, be called for short " RACH ") go up to UTRAN transmission RRC connection request message, simultaneously, counter V300 adds 1, and restarts timer T300; On the other hand, if above-mentioned counter V300 greater than variable N300, then UE enters idle (IDLE) state.
As seen when UE sends RRC connection request message and do not receive that message is set up in the RRC connection, can repeat to send RRC connection request message, set up message until receiving that RRC connects, specified thresholding stops when perhaps surpassing in advance because of the repeating transmission number of times.Therefore, both guaranteed higher call completing rate if want to reach, and reduced the purpose of the wasting of resources again as far as possible, very crucial problem is how correctly to handle the RRC connection request message that UE repeats to send in an access procedure.
It is such that a kind of processing method based on above-mentioned agreement is arranged: when the UTRAN side is received the RRC connection request message that UE sends, can distribute UTRAN side resource for it, and as shown in Figure 1, send RRC to UE and connect and set up message.
But, because it is with Unacknowledged Mode (Unacknowledged Mode that message is set up in the RRC connection, be called for short " UM ") go up at public control channel (Common Control Channel is called for short " CCCH ") and send, may lose and cause UE can't determine that RRC connects whether setting up.In this case, as mentioned above, message is set up in connection if UE does not receive RRC yet after timer T300 is overtime, may send a RRC connection request message to the UTRAN side once more.
According to present way, the UTRAN side is not done any uniqueness inspection to each bar RRC connection request message of receiving, and according to the description of above-mentioned agreement, the resource of distribution network side sends the RRC connection to UE then and sets up message without exception.
In this case, UE receive from the RRC of UTRAN side connect set up message after, to UTRAN side feedback RRC connection setup complete message, need to prove, UE only can respond a RRC connection and set up message and feed back the RRC connection setup complete message, and thus, the resource that other RRC connection building process takies is not because obtain the response of UE, finally can be released, avoid unnecessary resource occupied.
In actual applications, such scheme can cause ample resources waste in the short time.For example, a UE has sent RRC connection request message to the UTRAN side in an access procedure, the UTRAN side is distributed UTRAN side resource for it, sends the RRC connection to UE subsequently and sets up message, second-rate because of air interface signals, cause this message in process of transmitting, to be lost.UE can send RRC connection request message to the UTRAN side once more at this moment, and same UTRAN side is that it distributes UTRAN side resource once more, and sets up message to UE transmission RRC connection.Thus, the RRC connection request that the UTRAN side repeats to send for a UE has distributed two cover TRAN side resources, and a unnecessary cover UTRAN resource only just can discharge after the RRC connection setup complete message of waiting for UE is overtime, has obviously caused the waste of network side resource.
Cause a main cause of this situation to be, as mentioned above, after the TRAN side is received the RRC connection request message of UE transmission, do not do any uniqueness inspection, whether distribute UTRAN side resource according to protocol description fully, be that UE repeats to initiate in an access procedure owing to can't distinguish two RRC connection request message.Cause the RRC connection request distribution of messages that same UE is repeated to send to overlap UTRAN side resource more, thereby cause the waste of UTRAN side resource.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of processing method of wireless resource control connection request message, makes RRC connection request message that UE is repeated to send in an access procedure no longer takes place, and distributes many cover UTRAN side resources.And make that user's call completing rate is higher.
In order to solve the problems of the technologies described above, the processing method of wireless resource control connection request message provided by the present invention comprises following steps:
A universal mobile telecommunications system grounding wireless access network side joint is received the wireless resource control connection request message from subscriber equipment, and judge whether have user's equipment uniqueness sign to identify consistent in the subscriber equipment sequence with subscriber equipment uniqueness in the described wireless resource control connection request message, if have, enter step C, otherwise enter step B;
B universal mobile telecommunications system grounding wireless access network side adds described subscriber equipment sequence with the sign of the subscriber equipment uniqueness in the described wireless resource control connection request message, and is described user equipment allocation resource, enters step D;

The Radio Resource control connection that E universal mobile telecommunications system grounding wireless access network side judges whether to receive described subscriber equipment feedback is set up and is finished message, if receive then the uniqueness sign of deleting subscriber equipment described in the described subscriber equipment sequence; If overtime not receiving then discharges and distributed to the resource of described subscriber equipment, and delete the uniqueness sign of subscriber equipment described in the described subscriber equipment sequence.
Wherein, described step C comprises following substep:
C1 adds 1 with the transmission number of times of wireless resource control connection request, enters step C2;
C2 judges whether described transmission number of times satisfies predetermined conditions, if satisfy, enters step C3, otherwise directly abandons this message, and flow process finishes;
C3 finds the resource of distributing to described subscriber equipment for the first time according to described subscriber equipment sequence, enters step D.
Described subscriber equipment sequence is arranged in radio network controller.
Described subscriber equipment sequence can adopt any one data structure in array, linear list, the chained list to realize.
Contain the uniqueness sign of the subscriber equipment that is in Radio Resource control request flow process and the sign of the resource corresponding in the described subscriber equipment sequence with described subscriber equipment.
Described step B comprises following substep:
B1 universal mobile telecommunications system grounding wireless access network side adds described subscriber equipment sequence with the sign of the subscriber equipment uniqueness in the described wireless resource control connection request message, enters step B2;
B2 universal mobile telecommunications system grounding wireless access network side judges whether into described subscriber equipment success Resources allocation, if enter step B4; Otherwise, enter step B3;
B3 universal mobile telecommunications system grounding wireless access network side direction subscriber equipment sends Radio Resource control connection refuse information, discharge the resource of having distributed to described subscriber equipment, and the uniqueness sign of deleting subscriber equipment described in the described subscriber equipment sequence, flow process finishes;
B4 universal mobile telecommunications system grounding wireless access network side in described subscriber equipment sequence, enters step D with the identification record of resource of successfully distributing to described subscriber equipment.
By relatively finding, technical scheme difference with the prior art of the present invention is, at first, the UTRAN side is checked the sign of the UE uniqueness in the RRC connection request message that receives, judgement is the request or the request of repetition for the first time, for the RRC connection request message that same UE repeats to initiate in an access procedure, the UTRAN side is only distributed a cover UTRAN side resource, thereby reduces the waste of resource;
Secondly, the repetition RRC connection request message that correspondence receives, UTRAN side repeatedly send the RRC connection to UE and set up message, avoid UM pattern RRC to connect and set up information drop-out, improve UE and correctly receive the probability that message is set up in the RRC connection, thereby improve user's call completing rate.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In the radio network controller (Radio Network Controller is called for short " RNC ") of UTRAN side, set up and safeguard the UE sequence of the current RRC of a being in connection building process.In the present invention, what is called is in the RRC connection building process, as shown in Figure 1, promptly refers to set up request message from UE to UTRAN side transmission RRC, connects the state of setting up between the end of failure rollback up to UE to UTRAN side transmission RRC connection setup complete message or RRC.Wherein, in the UE sequence, preserve the sign of resource in the uniqueness sign of the UE that is in above-mentioned flow process and the UTRAN corresponding with this UE.In addition, sequence can adopt array, linear list, chained list and other mode data structures to realize that the characteristics of sequence are that scale is less, safeguards fairly simplely, and overhead is little, is convenient to realization.
Below in conjunction with the flow chart among Fig. 2, specify processing method according to RRC connection request message of the present invention.
At first in step 100, the UTRAN side is received the RRC connection request message that is sent by UE, enters step 200 subsequently.Wherein, the uniqueness sign that includes this UE in the RRC connection request message.
In step 200, the RNC of UTRAN side checks the RRC connection request message that receives, and judges that the UE uniqueness sign that comprised in this message is whether consistent with existing some UE uniqueness signs in the sequence that RNC safeguards.If in this step, judge and in sequence, do not find the UE uniqueness sign consistent, illustrate that this RRC connection request is the once new connection request of a UE, then enters step 300 with it; Otherwise,, illustrate that this UE sent same RRC connection request message to the UTRAN side before this, then entered step 705 if find the UE uniqueness sign consistent in the judgement sequence with it.
In step 300, owing to judge that in step 200 the RRC connection request is the once new connection request of a UE, so the uniqueness sign of this UE is added sequence, this measure shows that this UE has entered the RRC connection building process, after this enters step 400.
In step 400, the UTRAN side judges whether successfully to have distributed resource for this new connection request of this UE.If then enter step 600; Otherwise,, then enter step 500 if occur in the RRC connection building process causing the Resources allocation failure unusually.
In step 500, owing in a last step, be the connection request Resources allocation failure of UE, therefore in this step, UTRAN side direction UE sends the RRC connection refused message, after this enters step 920.
In step 600, because in step 400, the UTRAN side has been judged successfully and have been recorded in the sequence so will distribute to the resource identification of this UE in this step for this new connection request of this UE has distributed resource, so that sequence is safeguarded, after this enter step 810.
In step 705, because in step 200, find the uniqueness sign consistent in the sequence of UTRAN side in RNC with this UE, promptly this UE sent same RRC connection request message to the UTRAN side before this, therefore, in this step, the transmission number of times of RRC connection request is added 1, upgrade sending number of times, enter step 710.
In step 710, the UTRAN side judges whether above-mentioned transmission number of times satisfies predetermined conditions.In one embodiment of the invention, can by judge this number of times whether less than, or realize that smaller or equal to predefined thresholding this thresholding can be provided with reference to the N300 counter in the agreement.When the number of times that repeats to send same RRC connection request message as this UE surpasses thresholding, illustrating that RRC that the UTRAN side sends connects sets up message and always can't be received by UE because of losing, and in this case, the UTRAN side will take directly to abandon the method for this message, do not deal with, i.e. step 730; On the other hand, if above-mentioned number of times satisfies the thresholding condition, then enter step 720.
In step 720, the UTRAN lateral root is according to the uniqueness sign of this UE, and the record of distributing to the resource of this UE the relevant first time in the sequence, finds the resource of distributing to this UE, enters step 810.
Need to prove that the processing of above-mentioned steps 705, step 710 and step 720 has fully taken into account in UTRAN side direction UE transmission RRC connection and set up the situation that message is lost time and again, and taked to abandon the method for this message.Generally speaking, can above-mentioned situation not considered yet, because of having guaranteed in the agreement that UE can unrestrictedly not report RRC connection request message in an access procedure, the UTRAN side is directly according to described subscriber equipment sequence, for subscriber equipment finds the resource of distributing to it for the first time, after this enter step 810.
In step 810, the UTRAN side is assembled and is issued the RRC connection to subscriber equipment and sets up message, enters step 820.
In step 820, the UTRAN side judges whether to receive the RRC connection setup complete message of UE feedback, if receive the RRC connection setup complete message of UE feedback, enter step 910, in this step, the uniqueness sign of this UE can be deleted resource identification in the UTRAN corresponding with this UE simultaneously in the UTRAN side deletion sequence, show that RRC sets up successfully, enters follow-up flow process; Otherwise,, then enter step 920 if do not receive the RRC connection setup complete message, in this step, the UTRAN side discharges the UTRAN side resource of having distributed to UE, and the uniqueness of this UE identifies in the deletion sequence, can delete simultaneously the interior resource identification of UTRAN of this UE correspondence, flow process finishes.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
