At first, according to the present invention, an embodiment of the REG_RSP message be used to transmit the CID lastest imformation is described.
Fig. 3 representes according to the present invention, is used to transmit the embodiment of form of the REG_RSP message of CID lastest imformation.Similar with Fig. 1, Fig. 3 also representes to be used for to transmit the form of part of lastest imformation of a CID of REG_RSP message.Yet REG_RSP message shown in Figure 3 according to the present invention is different from traditional REG_RSP message shown in Figure 1.That is, REG_RSP message shown in Figure 3 comprises 6 byte CID lastest imformation fields 100 of the lastest imformation of inserting a CID, and the variable-length link information field 104 of inserting link information.CID lastest imformation field 100 comprise the type information that inserts integrated CID 1 byte field 106, insert 1 byte length field 108 of the length information of integrated CID and the 4 byte integrated CID fields 110 of inserting the value of integrated CID.
The CID lastest imformation field 10 of traditional REG_RSP message requires the 1 byte type relevant with new CID and length field 14 and 16 and 1 byte type and length field 20 and 22 relevant with old CID, and is as shown in Figure 1.Yet, only comprise and relevant 1 byte type field 106 and the 1 byte length field 108 of integrated CID of inserting new and old CID according to the CID lastest imformation field 100 of REG_RSP message of the present invention.Therefore, prior art needs 4 byte count data field to represent type and the length relevant with the CID lastest imformation, and the present invention only requires 2 byte count data field to represent type and the length relevant with the CID lastest imformation.
Compared with prior art, the present invention can derive every CID2 byte from the length of REG_RSP message, when carrying out switching, will be sent to the switching target terminal from the CID lastest imformation that BS (base station) transmits.For example, when 16 CID are used at supposition switching target terminal, when using, be used to transmit in transmission aspect the REG_RSP message of CID lastest imformation, can reduce the volume of transmitted data of 32 bytes (=2 bytes * 16) according to message format of the present invention.Therefore, in wireless access communication system, can increase the efficient of transmission of messages.
Fig. 3 example description integrated CID field 110 only comprises the example of new CID field 112 and old CID field 114.Yet, can type that be divided into the field relevant with new and old CID and any one of length field 106 and 108 can be included in the integrated CID field 110.For example, through making integrated CID field 110 expansions 2 bytes, replace shifting out length field 108; Before new CID field 112, increase and new 1 relevant byte length field of CID, and before old CID field 114; Increase by the 1 byte length field relevant, can constitute integrated CID field 110 with old CID.Perhaps, through making integrated CID field 110 expansions 2 bytes, replace shifting out type field 106; Before new CID field 112, increase and new 1 relevant byte type field of CID, and before old CID field 114; Increase by the 1 byte type field relevant, can constitute integrated CID field 110 with old CID.Therefore, compare, use these alternate embodiments, make the every CID of length of the REG_RSP message that transmits the CID lastest imformation be reduced by at least 1 byte with the length of traditional REG_RSP message.In addition, compared with prior art, the present invention also is reduced in transmission and is used for transmitting the volume of transmitted data that CID upgrades Pi REG_RSP message.
Fig. 4 be example description according to the present invention, be used to transmit the block diagram of an embodiment of the device of the REG_RSP message that transmits the CID lastest imformation.The device that is used to transmit REG_RSP message comprises integrated CID generation portion 200, REG_RSP message generation portion 202 and REG_RSP transmission of messages portion 204.For example, can programme integrated CID generation portion 200 and REG_RSP message generation portion 202 for use in the controller that generates REG_RSP message and the REG_RSP message that is generated is sent to user side in the BS (base station) that uses wireless access communication system of the present invention execution according to the process of flow chart shown in Figure 5.
With reference to Figure 4 and 5; In the time must will being used to transmit CID and upgrading Pi REG_RSP message and be sent to the switching target user side; In step 300 shown in Figure 5, the 200 comprehensive old and new CID of integrated CID generation portion are so that generate integrated CID and the integrated CID that is generated is provided to REG_RSP generation portion 202.Then, in step 302, REG_RSP message generation portion 202 generates the REG_RSP message that comprises integrated CID as shown in Figure 3, and in step 304, and REG_RSP transmission of messages portion 204 is sent to the switching target user side with the REG_RSP message that is generated.The switching target user side receives the REG_RSP message of being transmitted, and by type and length field 106 and 108 of definition as shown in Figure 3, confirms type and the length relevant with integrated CID, and confirms to be present in the new and old CID in the integrated CID field.
Be used to transmit the TRF_IND message of traffic indication information
Now, will be according to the present invention, the embodiment of the TRF_IND message that is used to transmit traffic indication information is described.
At first, with the characteristic of describing the BCID (basic connector identifier) that representes each user side in the TRF_IND message.According to the IEEE802.16e standard, BS (base station) has " m " individual BCID of 0x0001 to m.Wherein, the sum at the terminal that m representes to be supported by BS, and can between BS, be provided with differently.Typically, m is arranged to 100 and 200 value.If m is 200, only use 8 least significant bits of 16 among each BCID, can between user side, distinguish corresponding BS.That is, because 2
8=256, therefore, BS can use 8 least significant bits of BCID value to distinguish 200 user sides, needn't use the BCID value all 16.Therefore; As 8 least significant bits of BCID rather than whole 16 when being included in the TRF_IND message; BS can distinguish user side and can make the length of TRF_IND message whenever be included in the validated user end in the TRF_IND message, reduces 8, therefore can obtain to reduce the effect of volume of transmitted data.In another example, if m is 100, only use 16 7 least significant bits (least significant bit) among each BCID, corresponding BS can distinguish user side.That is, because 2
7=128, therefore, only use 7 least significant bit BCID values, BS can distinguish 100 user sides.Therefore,, reduce 9, therefore, can obtain to reduce the effect of volume of transmitted data when 7 least significant bits of BCID rather than whole 16 can make the length of TRF_IND message whenever be included in the validated user end in the TRF_IND message when being included in the TRF_IND message.Therefore be increased in the efficient of the control messages transmission of transmission TRF_IND message in the wireless access communication system.
Replace existing 16 BCID, only be called " short BCID " in this manual by predetermined a plurality of the BCID that constitute less than 16.According to the present invention, short BCID comprises the required minimum number of bits in each terminal of identification.Preferably, constitute short BCID by the predetermined a plurality of least significant bits among 16 of BCID.
BS uses different m values, but does not use whole 16 of BCID, and corresponding BS can distinguish all user sides of really serving from the BS reception.When considering this moment, in the BS of wireless access communication system of the present invention, the figure place that can will lack BCID is arranged to any number of 7 and 15 interdigits, for example 12 regularly.Because according to the m position that is used among each BS, the quantity that can be used on the BCID position among each BS is different, and it can be set changeably.That is,, can preset the figure place of short BCID changeably according to the sum that can receive the user side of service from each BS.Simultaneously; When the figure place of short BCID is variable (be not fixedly figure place); Preferably, the information of the figure place of the short BCID of expression is included in the TRF_IND message, can discern the figure place that is included in the short BCID in the TRF_IND message that is received so that receive the user of TRF_IND message.
Fig. 6 representes according to the present invention, an embodiment of the form of traffic indicator (TRF_IND), and expression is provided with the example of the figure place of short BCID regularly.TRF_IND message comprises 8 management message type field 400 inserting the management message type information, and 8 bit fields 402 of inserting the information of the quantity of representing the validated user end, and is as shown in Figure 2.Yet TRF_IND message shown in Figure 6 comprises that replacement is as shown in Figure 2, is inserted with 16 BCID fields 34 to 36 of 16 BCID of valid user end, one or more 12 short BCID fields 404 to 406 of the quantity of corresponding validated user end.TRF_IND message shown in Figure 6 representes that the figure place that will lack BCID is arranged to 12 example regularly.The figure place that can will lack BCID is set to any number of 7 and 15 regularly.
Fig. 7 example description is according to the present invention, the embodiment of the form of TRF_IND message, and expression is provided with the example of the figure place of the short BCID among each BS changeably.TRF_IND message comprises 8 management message type field 400 inserting the management message type information, and 8 bit fields 402 of inserting the information of the quantity of representing the validated user end.Because TRF_IND message shown in Figure 7 comprises the variable situation of figure place of short BCID, after further comprising 4 bit fields 408 of the figure place of representing short BCID and being positioned at the field 402 of the quantity of representing the validated user end.Short BCID field 410 to 412 is after field 408.The short BCID that can will have the figure place of variable setting in each BS is inserted in the short BCID field 410 to 412.The figure place of short BCID is by the information representation of inserting in the field 408.
When use has the TRF_IND message of form shown in Figure 7, increase the field of the short BCID figure place of expression.Therefore, when the figure place of short BCID is 12, compare, make the length of TRF_IND message increase by 4 with the length of TRF_IND message shown in Figure 6.Yet,, can make the figure place of short BCID be reduced to 7 usually, so that can further shorten the length of TRF_IND message according to BS.
Fig. 8 example description is according to the present invention, is used to transmit the block diagram of an embodiment of the device of TRF_IND message.The device that is used to transmit TRF_IND message comprises short BCID extracting part 500, TRF_IND message generation portion 502 and TRF_IND transmission of messages portion 504.For example, can programme short BCID extracting part 500 and TRF_IND message generation portion 502 for use in generating TRF_IND message and the TRF_IND transmission of messages that is generated is carried out the process according to flow chart shown in Figure 9 to the controller of user side in the BS (base station) that uses wireless access communication system of the present invention.
With reference to figure 8 and 9; In the time must will being used for traffic carried and representing that the TRF_IND message of information is sent to one or more switching target user side; In step 600 shown in Figure 9 and 602; Short BCID extracting part 500 is through reading the BCID of validated user end, and the short BCID that is extracted is provided to TRF_IND message generation portion, extracts and lacks BCID.At this moment; When as shown in Figure 6; When the figure place of short BCID was set regularly, short BCID extracting part 500 extracted the short BCID that is made up of fixing a plurality of least significant bits respectively, and when as shown in Figure 7; When the figure place of short BCID is set changeably, extract the short BCID that constitutes by variable a plurality of least significant bits respectively.
Subsequently, in step 604, TRF_IND message generation portion 502 generates the TRF_IND message that comprises short BCID, like Fig. 6 or 7, and in step 606, the TRF_IND message that 504 broadcasting of TRF_IND transmission of messages portion are generated.
