Described four DCCH carry RRC message according to following criterion:
SRB1 is used for all and goes up the message that sends at DCCH and RLC-UM (the Radio Link control of Unacknowledged Mode);
SRB2 be used for except direct-sending message all go up the message that sends at DCCH and RLC-AM (the Radio Link control of affirmation mode), comprise and transmit rrc layer message, be called for short RRC message;
SRB3 is used to transmit the high priority direct-sending message of higher layer message, uses DCCH and RLC-AM;
SRB4 is optionally, is used to transmit the low priority direct-sending message of higher layer message, uses DCCH and RLC-AM; RRC can know its priority according to the title of higher layer message, such as, the name of message is called SMS (short message), then is low priority message.
Rrc layer has been divided into high priority when the transmission higher layer message and low priority is handled respectively, but then lacks such treatment mechanism in transmission rrc layer message.Some is used to set up radio bearer in the RRC message, belong to high-priority message, some message then belongs to low priority message, and such as measuring control messages and some measurement report message, two kinds of message mix transmission and cause high-priority message in time not transmit probably.

Fig. 2 is the structural representation of DCCH provided by the invention.
Embodiment
Core of the present invention is that processed is distinguished in the transmission of rrc layer message.
Several implementations below the present invention has mainly adopted in implementation procedure:
(1) on the basis of existing DCCH structure, increases the RLC entity, and transmission RRC is provided on this RLC entity the new SRB of message, it is cooperatively interacted with original SRB that is used to transmit RRC message make RRC message when transmitting, can distinguish different priority;
(2) RRC is to the priority of the RRC message of every the needs transmission of RLC2 indication that is used to transmit RRC message, and RLC2 is to the RRC message of MAC (medium access control) layer of prioritised transmission high priority;
(3) when rrc layer has many message to be transmitted need be submitted to the RLC2 transmission simultaneously, then submit the RRC message of high priority earlier to RLC2, to guarantee preferentially being transmitted of high priority RRC message by RLC2 by rrc layer.
For the present invention there being further understanding, several implementations of the present invention are described in detail below in conjunction with accompanying drawing.
First kind of specific implementation provided by the invention is:
On the basis on the prior art, increase the RLC5 entity, and transmission RRC is provided on this RLC5 entity the Signaling Radio Bearer SRB5 of message, as shown in Figure 2, be used to transmit the RRC message of low priority, use DCCH and RLC-AM.Adopt original SRB2 then to be used to transmit the RRC message of high priority, use DCCH and RLC-AM, certainly, otherwise also can.
When configuration SRB, the priority of SRB2 is configured to be higher than the priority of SRB5.The needs of the high priority of the RRC message that relates to wireless channel configuration related procedure transmit on SRB2 with the RRC message of AM (affirmation mode), and the RRC message of the low priority of other AM pattern is then transmitted on SRB5.For example, physical channel is reshuffled, transmission channel is reshuffled, radio bearer is reshuffled relevant message and need be transmitted on SRB2, to guarantee the priority of its transmission, improves the network service performance; Then can on SRB5, transmit for the message of measuring, location positioning is relevant, thereby can avoid the transmission of such low priority RRC messages affect high priority RRC message.
Certainly, described high low priority RRC message can comprise other message, perhaps, adopts other the definite high low priority RRC message of priority dividing mode.
Second kind of specific implementation provided by the invention is:
At rrc layer and be used to transmit between the RLC entity of RRC message and increase the message priority indication information, the precedence information of each RRC message is offered described RLC entity by this indication information.At rrc layer when the RLC2 entity sends RRC message, indicate the priority of its every RRC message that need send, specifically can comprise high and low two priority, also can comprise more priority level, the receiving terminal of this RLC entity is configured to not need to submit according to the order of sequence transmit the RRC message that receives, but determines that according to the precedence information of each RRC message transmission successively in proper order.
Be specially: when the RLC2 entity when the MAC layer sends data block, at first determine the data block of the high priority RRC message correspondence in each RRC message, then, preferentially send the data block of high priority RRC message correspondence to the MAC layer, after the transmission of high-priority data piece finishes, send the data block of low priority RRC message correspondence again.Like this, can guarantee that just the RRC message of high priority can not be subjected to sending the RRC messages affect of low priority, and can be transmitted reliably.
For example, for physical channel reshuffle, transmission channel is reshuffled, radio bearer is reshuffled relevant message and can be set to high priority, when needs transmit such RRC message, then the precedence information of such message is offered the RLC2 entity, and preferentially transmit by the RLC2 entity by RRC; Then can be set to low priority for the message of measuring, location positioning is relevant, after the RLC2 entity is sent completely high priority RRC message, send this RRC message.
The third specific implementation provided by the invention is:
When RRC has many RRC message that need send to submit to the RLC2 entity transmission simultaneously, then by the priority of RRC according to every RRC message, the RRC message that priority is high is submitted to the RLC2 entity earlier, described priority equally specifically can comprise high and low two priority, or more priority level.At this moment, only need transmit processing according to the order of the RRC message that receives can guarantee that promptly the high RRC message of priority is preferentially transmitted on the RLC2 entity, and the RRC message that priority is low then can send after high priority RRCX message.
Such as, for physical channel reshuffle, transmission channel is reshuffled, radio bearer is reshuffled relevant message and is set to high priority, by rrc layer such RRC message can preferentially be submitted to the RLC2 entity; Be set to low priority for the message of measuring, location positioning is relevant, after rrc layer has been submitted high priority RRC message, submit the RRC message of this low priority class again to the RLC2 entity, thereby realized that the difference priority in the WCDMA system sends RRC message.
In sum, can distinguish the RRC message of different priorities, guaranteeing the timely transmission of high priority RRC message, thereby effectively improve the reliability of wireless communication system communicating by the present invention.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
