Abstract
The invention discloses an allocation method of a message transaction identifier in a WiMAX system, and the allocation method comprises the following steps: S302, whether a message transaction is related to a specific user terminal or not is judged; S304, whether the message transaction is a first message transaction in a group of message transactions of specific function which are sent to a target end or not is judged under the situation that the message transaction is unrelated to the specific user terminal; and S306, the message transaction identifier is allocated to the message transaction according to the judgment result of the step S304. The allocation method optimizes the transaction ID allocation process of MS which is in an idle state, thereby improving the transaction ID allocation mechanism which is unrelated to the specific user terminal.
Description
Technical field
The present invention relates to the communications field, relate more specifically to the message transaction signature number distribution method in a kind of WiMAX system.
Background technology
The main member of WiMAX inserting of microwave whole world interoperability authentication industry alliance comprises equipment manufacturers, device supplier and operator etc.Its main task is by product being carried out the authentication of compatibility and interoperability, eliminate the obstacle of IEEE802.16 standard application, enlarging the range of application of standard.802.16 series standard has defined the wireless access technology air-interface standard of WiMAX, representative standard comprises that 802.16d fixed wireless access and 802.16e mobile wireless insert standard.
WiMAX Forum has defined its network reference model, and Access Network (Access ServiceNetwork is called for short ASN) is made of base station (Base Station is called for short BS) and IAD (Access Service Network Gateway is called for short ASNGW).Defined some functional reference points therebetween again, the interface between the BS is the R8 reference point, and the interface between the ASNGW is the R4 reference point, and the interface between BS and the ASNGW is the R6 reference point.The interface that has defined simultaneously between ASN and the user terminal (Mobile Station is called for short MS) is the R1 reference point.Wherein, the R1 reference point promptly is the range of definition of IEEE802.16 standard family.MS and core net have defined a virtual interface R2 reference point between (Connectivity Service Network is called for short CSN), and the interface of ASN and CSN is the R3 reference point, and the interface between the CSN is the R5 reference point, and the R7 reference point is the internal interface of ASNGW.
At each above functional reference point, all there is the situation of the concurrent processing of message.We call affairs to the conversation procedure of a message, affairs are generally according to the number difference of comprising of message, can be divided into 3 classes, comprise three steps shake hands (message three: request, response and reply), two steps shook hands (message two: request and confirm) and a step shakes hands (a piece of news: indication).
For example, in the R1 reference point, the associative operation of Business Stream just exists concurrent.This concurrent in order to handle, indicate each different affairs, the IEEE802.16-2004 agreement has defined message transaction signature number (Transaction ID) field in DSA, DSC and DSD message.
Equally, in the communication process of intercommunication reference point R4, the R6 of ASN and R8, also there be the concurrent of this message.In order to handle this situation, WiMAX Forum network work group has also defined the Transaction id field in the intercommunicating message header of ASN.This field is distributed by the originating end of affairs, all equates in several message of affairs.Can also realize the out of order detection of message by this field.
WiMAX Forum subordinate's network work group NWG is in the NWG Stage3 agreement of definition, regulation Transaction ID is four Yuans group { sender IP addresses, recipient IP address, the MAC Address of related terminal, message institute function of dominant group } interior unique, first affairs Transaction ID of this function group at random non-0 the value, thereafter add one, if exceed 65535, then circulation is 1 (promptly to ask mould to 65536 at every turn, if be 0, then change 1 into).0 value of Transaction ID is invalid.
Agreement has also defined the R bit that Transaction ID resets in message header, transmitting terminal needs set R bit in the Transaction ID that resets.The TransactionID that resets is meant that transmitting terminal is re-set as non-0 random value to Transaction ID in order to obtain the synchronous of Transaction ID.Agreement regulation resets and comprises on opportunity of Transaction ID: MS is from state of activation (Idle) state that enters the free time; MS enters state of activation from the Idle state; And MS insert (or re-accessing) or switch finish after, with respect to first affairs of a certain specific function, just for article one message of a specific four-tuple.
By distribution and the operating specification of this cover Transaction ID, a plurality of concurrent affairs when we can distinguish ASN communication effectively, and whether can detect message out of order.
But we can not handle some and the affairs that concrete MS has nothing to do according to above-mentioned agreement; MS is under the idle state, does not preserve any information at BS, the processing of the affairs that BS sends is also difficult, because will guarantee the continuity of Transaction ID this moment, must set up corresponding object at BS, waste the BS resource like this, also bring difficulty to management.
For example, most message of RRM are all irrelevant with specific MS, as shown in Figure 1, BS radio-resource-configuration between the ASN more R4/R6 radio configuration in the new technological process is upgraded the affairs that (Radio_Config_Update) affairs (comprise radio configuration update request (Radio_Config_Update_Req) and radio configuration upgrade response (Radio_Config_Update_Rpt) message) are and specific MS has nothing to do, according to present protocol requirement, we can't be this affairs distribution T ransaction ID.
For example in position shown in Figure 2 more in the new technological process, MS is in idle condition, according to WiMAX NWG agreement and IEEE802.16 agreement, is not recommended in BS this moment and goes up any MS information of preserving again.Therefore, if this MS initiates more new technological process of twice position under some BS, when sending R6 message, BS just is difficult to guarantee that the Transaction ID of these twice affairs is continuous, unless preserve the information of this MS at BS.
Summary of the invention
One or more problems in view of the above the invention provides the message transaction signature number distribution method in a kind of WiMAX system.
According to a kind of message transaction signature number distribution method of the present invention, may further comprise the steps: S302, judge whether message transaction is relevant with specific user terminal; S304 under the irrelevant situation of message transaction and specific user terminal, judges that whether message transaction is first message transaction that sends in the message transaction of one group of specific function of destination; And S306, according to the judged result of step S304, be message transaction assignment messages Transaction Identifier number.
Wherein, be to send under the situation of first message transaction in the message transaction of one group of specific function of destination at message transaction, be that message transaction distributes the arbitrary value between 1 to 65535, and reseting mark is carried out set.At message transaction is not to send under the situation of first message transaction in the message transaction of one group of specific function of destination, is the message transaction identification number of the message transaction signature number big 1 of the last message transaction of message transaction distribution ratio.And, add 1 at the message transaction signature number of last message transaction and equal under 65535 the situation, be message transaction assignment messages Transaction Identifier number 1.Wherein, message transaction signature number is unique in tlv triple { sender IP address, recipient IP address, message institute function of dominant group }.
According to another kind of message transaction signature number distribution method of the present invention, may further comprise the steps: S302, judge whether message transaction is relevant with specific user terminal; S308 under the message transaction situation relevant with specific user terminal, judges whether the transmitting terminal of message transaction preserves the information of specific user terminal; S310 according to the judged result of step S308, is message transaction assignment messages transaction signature number.
Wherein, do not preserve at the transmitting terminal of message transaction under the situation of information of specific user terminal,, and reseting mark is carried out set for message transaction distributes between 1 arbitrary value of putting between 65535.Preserve at the transmitting terminal of message transaction under the situation of information of specific user terminal, step S310 may further comprise the steps: S3102, judge that whether message transaction is first message transaction that sends in the message transaction of one group of specific function of destination; And S3104, at message transaction is to send under the situation of first message transaction in the message transaction of one group of specific function of destination, be the arbitrary value of message transaction distribution between 1 to 65535, and reseting mark carried out set, otherwise be the message transaction identification number of the message transaction signature number big 1 of the last message transaction of message transaction distribution ratio.And, add 1 at the message transaction signature number of last message transaction and equal under 65535 the situation, be message transaction assignment messages Transaction Identifier number 1.Wherein, message transaction signature number is unique in four-tuple { sender IP address, recipient IP address, the MAC Address of specific user terminal, message institute function of dominant group }.
By the present invention, can handle irrelevant message effectively, and can optimize MS and be under the idle condition, not the TransactionID allocation strategy when BS preserves any information with concrete MS.

Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
In the present invention, for the irrelevant affairs of specific MS, only require that Transaction ID is three Yuans group { sender IP addresses, recipient IP address, message institute function of dominant group } interior unique, when sending first Transaction of this tlv triple, the Transaction ID that resets, set R bit.And enter idle condition at MS, BS need send the affairs that are associated with this MS, and does not keep on this BS under the situation of any this MS information, equal set R bit when at every turn sending affairs, and establishing Transaction ID is random value.
With reference to figure 3, the message transaction signature number distribution method according to the embodiment of the invention is described.As shown in Figure 3, this message transaction signature number distribution method divides 3 branches to carry out:
S302 judges whether message transaction is relevant with specific MS.
S304 when sending a message transaction that has nothing to do with specific MS, judges that at first whether this message transaction is first message transaction that sends to destination under the function of affairs correspondence.
S306 is if then getting Transaction ID is random value, the set-reset sign; If not, the Transaction ID that then adopted sent last time added for 1 (exceed 65535, then equal 1).
S308 when the message transaction that sends is relevant with specific MS, judges whether the transmitting terminal of message transaction preserves the information of specific MS.
S310, if do not preserve any MS information, then getting Transaction ID is random value, the set-reset sign.If preserve MS information, then carry out following steps:
S3102 judges that whether message transaction is first message transaction that sends in the message transaction of one group of specific function of destination;
S3104, at message transaction is to send under the situation of first message transaction in the message transaction of one group of specific function of destination, be the arbitrary value of message transaction distribution between 1 to 65535, and reseting mark carried out set, otherwise be the message transaction identification number of the message transaction signature number big 1 of the last message transaction of message transaction distribution ratio.
For above-mentioned radio resource management messages, can in 3 tuples, give message transaction distribution T ransaction ID.If message transaction is the message transaction of first transmission in the tlv triple, then set R bit distributes non-0 value at random to give Transaction ID.
For location update message, BS is each when sending set R bit all distributes non-0 value at random to give Transaction ID.
In sum, adopt message transaction signature number distribution method provided by the invention can realize the affairs Transaction ID distribution irrelevant with specific MS, can also optimize the Transaction ID allocation flow that MS is in idle condition, improve the Transaction ID mechanism of WiMAX.
Above-mentioned is that the present invention is equally applicable to the application of other reference point of WiMAX in the situation of ASN with interior each reference point communication.
The above is embodiments of the invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
