Abstract
The present invention discloses a sequential control method for messages of an access layer and a non access layer. The method can avoid errors of the sending and receiving time sequences of a straight transmission message and a signaling message so as to prevent the straight transmission message from being discarded because the arrival time of the straight transmission message to user equipment is later than that of the signaling message. The sequential control method for messages of an access layer and a non access layer comprises the following steps: A, the signaling message is transmitted to a wireless network controller by a core network; B, the side of a ground wireless access network of a general mobile telecommunication system judges whether a current corresponding domain is transmitting a down straight transmission message or not; if the current corresponding domain is transmitting a down straight transmission message, a step C is carried out, and if the current corresponding domain is not transmitting a down straight transmission message, a step D is carried out; C, the side of the ground wireless access network of the general mobile telecommunication system enters the step D after the transmission of the straight transmission message is completed; D, the signaling message is transmitted to the user equipment by the wireless network controller.
Description
Technical field
The present invention relates to the sequential control method of messaging in the mobile communication system, particularly in the mobile communication system, the sequential control method of Access Layer and Non-Access Stratum messaging.
Background technology
At existing Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, abbreviation " WCDMA ") in the communication system, when calling out, at first set up the signaling plane (comprising transport network layer and wireless network layer signaling plane) of Access Layer, then set up the Non-Access Stratum signaling plane, when discharging, then at first finish alternately by the non-access layer information of core net and subscriber equipment, trigger the release of Access Layer signaling plane then by core net.
About the interaction flow of Access Layer signaling message and Non-Access Stratum direct-sending message,, especially among 3GPP TS 25.331 V3.7.0 that publish June calendar year 2001 and 3GPPTS 23.122 V3.7.0 detailed description is arranged in the said process in the 3GPP serial protocols.
But, the problem that Non-Access Stratum direct-sending message and Access Layer signaling message are received and dispatched the sequential mistake can take place in some cases.Reason is as follows: when Access Layer signaling message and Non-Access Stratum direct-sending message occur alternately, and core net is at first passed through the IU interface to universal mobile telecommunications system grounding wireless access network (UMTSTerrestrial Radio Access Network, abbreviation " UTRAN ") issues the Non-Access Stratum direct-sending message, then when UTRAN issues the Access Layer signaling message, for the direct-sending message of Non-Access Stratum, UTRAN does not do any processing and directly passes through subscriber equipment at once; On the other hand, for the signaling message of Access Layer, UTRAN also sends to subscriber equipment at once.But two kinds of message send by different channels, signaling message is from Signaling Radio Bearer (Signalling Radio Bearing, being called for short " SRB ") wireless chain control layer of 1 correspondence issues, and direct-sending message issues from the wireless chain control layer of SRB3 or SRB4 correspondence.Under normal conditions, the priority of SRB1 is higher than the priority of SRB3 and SRB4, so system can preferentially send signaling message.In addition, signaling message is generally less, and direct-sending message is bigger, also influential to transmission speed, thus being more prone to cause issues direct-sending message earlier in core net, after issue under the situation of signaling message, subscriber equipment is received signaling message on the contrary earlier, after receive direct-sending message.
Fig. 1 illustrates the concrete example of a transmitting-receiving direct-sending message and signaling message.In Fig. 1, at first send " INITIAL DIRECT TRANSFER " (initial direct-sending) message to UTRAN by subscriber equipment, UTRAN sends " INITIAL UE MESSAGE " (initial UE message) message to core net then, then, at first by the IU interface, the radio network controller in UTRAN issues direct-sending message to core net.Then, core net issues " IU RELEASE COMMAND " (IU release command) message by the IU interface again, and this message is signaling message.
Radio network controller (Radio Network Control is called for short " RNC ") is received this direct-sending message of direct-sending message rear line device forwards that core net issues; On the other hand, radio network controller is received the signaling message that core net issues, and promptly sends " RRC CONNECTIONRELEASE " (release of Radio Resource control connection) message to subscriber equipment.
As indicated above, signaling message " RRC CONNECTION RELEASE " issues from the wireless chain control layer of SRB1 correspondence, and direct-sending message " DIRECT TRANSFER " issues from the wireless chain control layer of SRB3 or SRB4 correspondence, because angle from priority, SRB1 is higher than SRB3 and SRB4, and signaling message is less, possible packet is more on the wireless chain control layer of SRB3 or SRB4 correspondence in addition, therefore can cause the incorrect order that direct-sending message and signaling message on the UU interface between radio network controller and the subscriber equipment, occur, promptly as shown in Figure 1, on the IU interface, direct-sending message arrives the UTRAN side before at signaling message " IU RELEASE COMMAND ", but on the UU interface, direct-sending message but is slower than signaling message " RRC CONNECTION RELEASE " and arrives user equipment side.
In this case, subscriber equipment will discharge Access Layer after receiving " RRC CONNECTION RELEASE ", thereby the Non-Access Stratum direct-sending message of receiving after causing is dropped, and can't be sent to the Non-Access Stratum of subscriber equipment.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of new Access Layer and the sequential control method of non-access layer information, this method can avoid direct-sending message and signaling message transmitting-receiving sequential to make a mistake, and prevents that direct-sending message is dropped owing to being later than signaling message arrival subscriber equipment.
In order to solve the problems of the technologies described above, the sequential control method of bright Access Layer that provides of we and non-access layer information comprises following steps:
The A core net sends signaling message to radio network controller;
B universal mobile telecommunications system grounding wireless access network side judges whether current corresponding field has descending direct-sending message to send, if having, then enters step C, if do not have, then enters step D;
C universal mobile telecommunications system grounding wireless access network side waits for that described direct-sending message transmission finishes, and enters step D;
The D radio network controller sends signaling message to subscriber equipment.
Wherein, in the described steps A, signaling message is to discharge class or configuration class signaling message.
Described step B comprises following steps: whether described radio network controller is judged to have in the current corresponding field and is sent to subscriber equipment, but do not receive the direct-sending message of acknowledgement message, if have, then universal mobile telecommunications system grounding wireless access network side judges that current corresponding field has descending direct-sending message to send, if no, judge that then current corresponding field does not have descending direct-sending message to send.
Described step C can realize in the following way:
Described radio network controller is waited for the acknowledgement message of described direct-sending message, receives that described acknowledgement message shows that promptly described direct-sending message transmission finishes, and enters step D.
Also comprise following steps among the described step C:
Overtime when described radio network controller wait from the acknowledgement message of the wireless chain control layer of user equipment side, trigger radio network controller by timer and issue described signaling message to subscriber equipment.
The timing length of described timer is set by network side.
By relatively finding, technical scheme difference with the prior art of the present invention is, when the universal mobile telecommunications system grounding wireless access network need be transmitted to subscriber equipment with signaling message, judge at first whether current corresponding field has descending direct-sending message to send, if have, after waiting for that then this direct-sending message transmission finishes, the side sends to subscriber equipment with described signaling message.
Difference on this technical scheme has brought comparatively significantly beneficial effect, has promptly avoided issuing to deliver letters in the situation that current corresponding field has descending direct-sending message sending making message.Thereby prevented the sequential mistake of transmitting-receiving signaling message and direct-sending message, and guaranteed that direct-sending message can correctly arrive subscriber equipment.
Description of drawings

Fig. 2 is a sequential control method flow chart according to an embodiment of the invention.
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.
Fig. 2 has described sequential control method flow chart according to an embodiment of the invention.As shown in Figure 2, in step 100, core net is by the IU interface, radio network controller to the UTRAN side sends signaling message, wherein, these signaling messages can be to discharge the class signaling message, for example " RADIOBEARER RELEASE " (radio bearer release) message, " SIGNALLING CONNECTIONRELEASE " (the signaling connection discharges) message and " RRC CONNECTION RELEASE " (Radio Resource is connected release) message etc.; Also can be configuration class signaling message, for example " RADIO BEARERRECONFIGURATION " (radio bearer is reshuffled) etc.After this enter step 200.
In step 200, after the UTRAN side is received above-mentioned signaling message, judge whether current corresponding field has descending direct-sending message to send, if having, then enters step 300, if do not have, then enter step 400.Wherein corresponding field is meant that this signaling connects the territory at place, for example CS (circuit switching) territory or PS (packet switching) territory.Only in current corresponding field, judge it is because the connection not in the same area is independently.
Here for a specific example, illustrate how the UTRAN side judges whether corresponding field has descending direct-sending message to send.
In the WCDMA communication system, direct-sending message is AM (Acknowledged Mode, all announcement mode) pattern, if therefore the radio network controller of UTRAN side sends direct-sending message by the UU interface to subscriber equipment, and this subscriber equipment is received direct-sending message, and the wireless chain control layer of user equipment side must return acknowledgement message to radio network controller.
That is to say, if radio network controller has sent direct-sending message by the UU interface to subscriber equipment, but do not receive the acknowledgement message that the wireless chain control layer from user equipment side returns, illustrate that then this direct-sending message does not correctly arrive subscriber equipment as yet, promptly current corresponding field is sending descending direct-sending message.
Therefore, radio network controller can be according to whether having sent direct-sending message to subscriber equipment in the current corresponding field, but the UTRAN side is not received the acknowledgement message that the wireless chain control layer from user equipment side returns as yet, has judged whether that descending direct-sending message sends.
According to above principle, if judged result is not send in the current corresponding field, still do not receive the direct-sending message of acknowledgement message, then expression does not have downstream message to send.This situation has two kinds of possibilities, a kind of radio network controller of the UTRAN of being side has sent direct-sending message by the UU interface to subscriber equipment, and direct-sending message has correctly arrived this subscriber equipment, thereby the wireless chain control layer of user equipment side has returned acknowledgement message to radio network controller.Another is that the radio network controller of UTRAN side sends direct-sending message to subscriber equipment.In both cases, all allow the radio network controller of UTRAN side directly direct-sending message to be handed down to subscriber equipment and can not cause the transmitting-receiving incorrect order of direct-sending message and signaling message.In this case, enter step 400.
On the other hand, if judged result is to have to send, still do not receive the direct-sending message of acknowledgement message as yet, then expression has descending direct-sending message to send.In this case, enter step 300.
In step 300, because in step 200, UTRAN judges that current corresponding field has descending direct-sending message to send, so before correctly receiving direct-sending message, receive signaling message earlier and the incorrect order of direct-sending message and signaling message take place for fear of subscriber equipment, therefore after waiting for that this direct-sending message transmission finishes, enter step 400, promptly the radio network controller of UTRAN side sends signaling message to subscriber equipment.
Specifically, in the present embodiment, the radio network controller of UTRAN side is waited for the acknowledgement message that the wireless chain control layer from user equipment side returns, and up to receiving this acknowledgement message, square tube is crossed the UU interface, sends signaling message to subscriber equipment.This scheme has guaranteed that well subscriber equipment can correctly receive the direct-sending message that the UTRAN side issues, and avoids because receive the phenomenon that causes direct-sending message to be dropped such as the signaling message that discharges class earlier.In addition; the radio network controller wait was protected by timer from the time of the acknowledgement message of the wireless chain control layer of user equipment side; if the situation from the acknowledgement message of user equipment side wireless chain control layer appears not receiving for a long time in the UTRAN side; be wait timeout, then trigger radio network controller and issue signaling message to subscriber equipment by the UU interface by above-mentioned timer expiry.
In step 400, radio network controller directly issues signaling message to subscriber equipment by the UU interface.
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.
