Abstract

A method serving as a protocol (and corresponding equipment) for use in communicating between a sending node (11) and a receiving node (12); a frame (10) including a spare extension (SE) section conveying values for one or more information element (IE) fields, and also including a new IE flags IE or other device for indicating to the receiving node (12) whether the SE section includes valid data for each IE in the SE section. A flag indicating whether valid data is provided in the SE section can be used, and also an IE indicating the length of the SE section. The method is such that the receiving node (12) treats an IE field value occurring in the SE section as spare bits if the IE field was introduced for a version of a later release of a specification than that according to which the receiving node (12) was implemented.

It is determined how the SE is used; if it is passed through Newt Γ.1E, it is difficult to find out IE because it is not known how to use it. For example, if IE is frozen by _... #日士乍杂, so when there is an important misunderstanding in the Rel-5 specification ^ ^ How to add a network 5, there is a need for a new positive. The frame structure shown in "Gang" will be understood. Referring to Chapter 3A and Member 2, if we add 1E to the ^6, we will follow the rules and report that it is difficult to find out where to add the new 1E to Rel_5. Correct important errors. : It is determined that the addition of the new Rel-5 IE will be followed by, if the new Rel_5 IE is added before the Rd_6 m, the change will be made to the two-way extended compatible Rd_6 specification. If the new "", "J," is added after the Rel_6 IE, the Rel_5 implementation can also understand the Rel_6 IE. Therefore, the present invention discloses how to use SE__ to add a new version, especially for accommodating early Version—examines how to indicate whether the SE is being used. In addition, the maximum size of the SEF in the control frame in the different frame protocols (ie TS25.425, TS25.427 and TS25.435) is 32 Bit, and the maximum size of the SEF in the agreement is only 2 octets, although J has no good reason for the difference in length. This small information frame alternate extension domain is confirmed by excessive restriction of SE. There are a number of problems. Therefore, the present invention also discloses the SE length in the information frame according to the above agreement. [Summary of the Invention] A first feature of the present invention is to provide a method for adding a SE to a 1265705 IE in a communication system. Figure 4 and Figure 5 show the frame extension mechanism in the above frame protocol specifications (TS25.425, TS25.427 and TS25.435) (for DCH, DSCH, HS_DSCH, RACH, FACH, etc.) Communicate) for (latest/latest version) Rel-5 It's not very clear, other versions are also the same. Although there is a definition of SE block, but how to use it is not specified. The definition of the SE block of the frame is only provided to the block of _2 octets. The new IE can be used in the future. The reverse compatibility mode is added. There is no specification so far (where and in what order in SE) to add a new IE. The 疋> column problem will be generated. If you have a new R in Rd_5 Specify a version (and the version of the version). After the frame agreement is frozen, you will not be able to include other IEs in the reverse compatible mode. However, (10)b is now (4) occurs at any time, such as person 2 When it is large, it must be positive (in existing version 4)

version). For this reason, in the case of R _ early J RNSAP (none, Yi Luzi 彡 料 份), and the appropriate definition - reverse compatible expansion mechanism; that is: ^ ' will join the new job message (in Application agreement; how to set the ^^f, f can be referred to as the message by the receiving node according to the earlier specifications. In the present invention, the initiative determines (ie, the reverse compatible extension mechanism in the agreement). Before the frame is made, the maximum size of the SE block in SE _ 4 of the frame is only 2 and the size is taken. In the frame of the eight-digit group, and the control frame 1265705 column expansion! To super-it,: eight: The invention is the frame of the frame ‘1 2 solid eight-bit 7〇 group. Here, it is explained that the φ system is assumed to be the frame of the frame and the 32 octets in the critically ill brothers enter the invention in the header portion of the Rei·99 frame, that is, for example, the header of the preparation Part of the spare position is as in the number 3 of the present invention. Definition of Qing (a dollar flag) 12 1 Instrumentation i Guangzhan It has a flag to indicate how it is in use or not. 〇 : The alternate extension is not in use. 2 · Standby extension.圧 contains more positive. Intercept length: 1 bit uses the SEF (-bit ray) of the present invention, and (4) J has any (one or more) new formulas that are defined in the alternate expansion; and: "Liqi flag" is "set" ; (ie set to, r or to display S, the other predetermined values of the blocks), then set the near-IE flag in the beginning part of the SE (or the current start part) The m is used to indicate which information exists in the bit of the se block after the bit of the new IE flag IE. The size of the new IE flag IE is such as an octet or two octets. Depends on 3GPP. It is shown here that it has been designated as a 5-bit in a version and then the 1265705 version is; the cell part ID of the East node and the cell ID of the cell are the first to be introduced, according to The present invention, preferably, first appears in the IE that occurs in the SE, regardless of how many late IEs are added and regardless of the first preferred version of the later version of the IE, the sample definition of the new IE flag IE is as follows:

New IE Flag IE Description: Flagged to indicate the presence of information in subsequent bits in the SE column. Value range: Bit 0: Indicates if the first bit of the lower column, 0-5, contains a valid cell ID (indicated by a value of 1) or not (indicated by a value of 0); Bits 1-15: Set to 0: Reserved for future use. Any indication flag should be ignored by the receiving node (implemented according to the version of the introduced Cell Part ID IE). Field length: 16 bits The description of the cell part ID IE is defined as follows:

The cell part IDf is divided by frequency (FDDVI indicates that the cell part ID indicates the part of the cell with the highest SIR during the RACH access process. The cell part ID is planned by O&M; M (Operation and Maintenance). Field: {0-63} Field length: 6 bits As mentioned above, the cell part ID IE shown in Fig. 6 is only a new type added by the SE column of 13 1265705 of the present invention - Example (IE flag The standard IE indicates that it occurs in SL·, and in some 'first indicated by the above-mentioned SEF, the SEF is ^^^^, the department is still: ^ and the certificate has at least one added pressure); ^^ How to add the SE to the SE in the frame (using the IE (value) example. According to the present invention, when the 3Gpp is added to the occasion, the late-added IE is preferably added to the cell part and the new type The flag of the IE flag IE will respond to the post-addition after the 'mark will be set or not set' depending on whether the transfer section should be the value of IE in the SE. Figure 6 shows how to put a Rel- 6 IE joins the alternate implementation. In this embodiment, bit 1 of the new IE flag IE is used to indicate that the first m after the new IE flag IE is No effective information. If another IE is added after adding the cell part IE) pressure (such as the embodiment IE shown in Fig. 7), the new IE flag bit (number) 1 indicates the second IE. (For example, whether the actual picture shown in Figure 7 is valid, that is, whether the transmitting node provides the second joining pressure. It should be known that the pressure represented by the flag of the new IE flag 1E should be able to cooperate with the SE column. 'This kind of IE is not necessarily octet ^^ IE flag IE flag does not need to correspond to octet, but can correspond to = relative IE, each as small as one bit or as many as eight Bits 2. In the embodiment shown in Figure 6, the new flag flag indicates the validity of the IE added by the fixed size SE field. If -IE is included, no matter what E exists, usually The system is set to 14 1265705 bits, which should know the flag of the later version.) Therefore, the flag m can be added to the frame for reverse compatibility. Figure 7 shows the Rel money in the present invention. The rach frame. In this case, the G-bit of the m-simplification and the 1-bit element of the new-type flag m will be set to display the cell part ID m and the embodiment圧Existence, and may cause the Rel-6 receiving node to understand (read) the cell part is still in the example IE. Conversely, Figure 8 shows the 2RACH frame in the Rel-99 specification. In this case, according to the present invention The new IE flag m is usually 0 (that is, it will be marked as a spare bit in the specification) and will be specified in the frame protocol specification (since it is relative to the new IE flag) The SE IE is only used in the later version.) In addition, the 1-bit of the new flag IE is set (in 1) in Rel-99 to indicate the validity of the embodiment m. An example of the definition of the new IE flag IE in Rel-99 is as follows: New IE Flag Description • Flags to indicate information that exists in the following bits. Value range: Bit 0: Reserved. This bit should be set to zero by the transmitter and ignored by the receiver. Bit 1: indicates that when the second bit after the new IE flag IE includes a valid embodiment, its value is 1, and in other cases its value is 〇; bits 2-15: set to 0. Reserved for this user plane version. Any indicator flag will be ignored by the receiver. Shelf length · 16 bits 16 1265705 In this embodiment, if one of the receiving nodes is a Rel-ό node, it will be able to understand the new IE flag IE bit and 1 bit, and according to the 〇 bit and 1 The value of the bit, the readable cell part is positive and the example is IE. If the receiving node is Rel_99, it will ignore the 〇 bit and the first octet, and use only 1 bit to determine whether the embodiment m IE exists in the frame. If so, the receiving node will attempt to read it. value. The transmitting node sets (or does not set) the flag of the new IE flag m based only on which IE the transmitting node implements and transmits to the transmitting node according to the transmitting node. In the above embodiment, the Rel-6 transmitting node will set (or not set the 〇 bit and the 丨 bit of the new IE flag IE (depending on the transmitting node; ^ no relative IE included in the frame). On the other hand, the Rel_99 transmitting node often sets the value of the 0th bit of the first bit of the new type of flag IE and SE column, and only sets (or does not set) the value of the 1st bit of the new positive flag. The bit value of the embodiment IE (as shown in the second bit) is set as appropriate.

Another alternative embodiment in which the SE uses the SE block is the SE length m in the first bit, as shown in Figure 9. In this alternative, the new θ of _ (ie, the size of the SE does not need to be preset). The substitution 1 flag 1 £ and the relative SE length are defined as follows: The declining standard H ·· has a flag to indicate the presence of information in the following bit towel. The detailed description - whether the first bit (bit 〇 _5) has a '77', if it is set to 1, otherwise set to 〇; 17 1265705 after the new $ ι ε flag 1 ε connected to the heart of the heart : 2 = flag no, if its value is 1, then the last existing new job title in the frame (4) block length · · 8 bit SE length including = the value of one of the fingers, such as 曰%% Upper feeding degree Since the IE can indicate up to 255, more new type 3 flag j 1E is within the indicated length range, which means that there is a longer length of the crime = ^ below: ^ before the field value: 1255 & ghost block Length: 8 bits still in the ST: bit flag) and the new m flag 1E and right hemp in the sink, but in this alternative the new 1E flag 1E i no two: 冓 (that is, each new type 1 £ flag The last bit of the label 1E will indicate the presence). $ IE flag under one block and corresponding to the 3 £ sub-section depends on the first place where the length pressure is set
