(c) if this action type is the refusal Transaction Identifier, then the refusal list information with the corresponding operation information sign of described Transaction Identifier centering with described number of transactions group element identifies set, and expression joins the corresponding signaling message that comprises in this radio resource management messages in the refusal tabulation;
(d) if this action type for ignoring Transaction Identifier, is not then carried out any processing, represent that the corresponding signaling message that comprises in this this radio resource management messages is left in the basket.
In the middle of reality is used, adopted static array to realize the method for TRANSACTIONS management in the method for the present invention.See also shown in Figure 2, wherein, MAX=MAX_RRC_MESSAGE_ID;
● Bit (0)=1 expression Transaction Identifier (transaction ID) is present in to be accepted in the tabulation;
● Bit (1)=1 expression Transaction Identifier (transaction ID) is present in the refusal tabulation;
The subscript of one-dimension array TRANSACTIONS is type of message id:RRC_message_id (0......MAX_RRC_MESSAGE_ID); Each element of array is a 8bits integer, and these 8 bit can be divided into 4 to (bit[2k], bit[2k+1]); K=0 wherein, 1......3 is in order to represent transaction id (k);
● bit[2k]=the transaction id (k) of 1 this signaling message of expression is present in and accepts in the tabulation (accept list), and 0 expression does not lie among the accept list;
● bit[2k+1]=the transaction id (k) of 1 this signaling message of expression is present in the refusal tabulation (reject list), and 0 expression does not lie among the reject list.
So each bit can have 4 kinds of values to (bit_pair):
● NON_ACCEPT_NON_REJECT (00b) expression transaction id (k) neither in the accept tabulation also not in the reject tabulation;
● ONLY_ACCEPT (01b) expression transaction id (k) only is present among the accept list;
● ONLY_REJECT (10b) expression transaction id only is present among the rrject list;
● ACCEPT_AND_REJECT (11b) expression transaction id (k) is present among accept list and the reject list.
Like this, when needs are safeguarded the transactions of a certain signaling message, as long as use the corresponding RRC_message_id of this message and corresponding transaction id (k) just can directly find corresponding bit_pair, then use this bit_pair and 00b, it is just passable that 01b, 10b or 11b do " with or " operation.
Concrete implementation procedure is as follows:
1, define arrays subscript, i.e. RRC_message_id:
typedef?enum
{
RRC_CONNECTION_SETUP_ID＝0，
RRC_CONNECTION_REJECT_ID＝1，
RRC_CONNECTION_RELEASE_ID＝2，
MEASUREMENT_CONTROL_ID＝3，
RADIO_BEARER_SETUP_ID＝4，
……
MAX_RRC_MESSAGE_ID
}RRC_Message_Id_e；
2, the TRANSACTIONS that defines arrays:
Unsigned?char?TRANSACTIONS[MAX_RRC_MESSAGE_ID]；
3, definition is to the operation of array element:
#define?ADD_TRANSACTION_ID_0_TO_ACCEPT_LIST?00000001b
#define?ADD_TRANSACTION_ID_0_TO_REJECT_LIST?00000010b
#define?ADD_TRANSACTION_ID_1_TO_ACCEPT_LIST?00000100b
#define?ADD_TRANSACTION_ID_1_TO_REJECT_LIST?00001000b
#define?ADD_TRANSACTION_ID_2_TO_ACCEPT_LIST?00010000b
#define?ADD_TRANSACTION_ID_2_TO_REJECT_LIST?00100000b
#define?ADD_TRANSACTION_ID_3_TO_ACCEPT_LIST?01000000b
#define?ADD_TRANSACTION_ID_3_TO_REJECT_LIST?10000000b
#define?EXIST_ELEM_IN_ACCEPT_LIST?01010101b
#define?EXIST_ELEM_IN_REJECT_LIST?10101010b
4, to the concrete management algorithm of TRANSACTIONS:
For the signaling message that current UE is received, at first find corresponding RRC_message_id by the definition in the step 1, then the array by definition in the step 2 visits corresponding element, can finish following operation to this element:
(1) search whether there is this kind signaling message among the accept list:
If ((element﹠amp; EXIST_ELEM_IN_ACCEPT_LIST)＞0) namely represent to exist among the accept list this kind signaling message;
(2) search whether there is this kind signaling message among the reject list:
If ((element﹠amp; EXIST_ELEM_IN_REJECT_LIST)＞0) namely represent to exist among the reject list this kind signaling message;
(3) search whether there is transaction id among the accept list be this kind signaling message of 2:
If ((element﹠amp; ADD_TRANSACTION_ID_2_TO_ACCEPT_LIST)＞0) namely represent to exist among the accept list this kind signaling message;
(4) be that this kind signaling message of 3 is increased among the accept list with transaction id:
element＝element|ADD_TRANSACTION_ID_3_TO_ACCEPT_LIST；
(5) be that this kind signaling message of 1 is increased among the reject list with transaction id:
element＝element|ADD_TRANSACTION_ID_1_TO_REJECT_LIST；
(6) empty all this kind message among the accept list:
element＝element?&?EXIST_ELEM_IN_REJECT_LIST；
(7) empty all this kind message among the reject list:
element＝element?&?EXIST_ELEM_IN_ACCEPT_LIST；
5, to the concrete processing mode of every kind of signaling message transaction id, should follow section8.6.3.11 and other descriptions everywhere among the TS25.331.
6, following when receiving RRC message to the example that is treated to of transaction id, method proposed by the invention is described, flow process as shown in Figure 3:
(1) receives a RRC message, suppose that the transaction id that comprises is 1;
(2) carry out the integrity protection inspection of this message, if failure then abandon it;
(3) according to the definition of array index in 1, in the TRANSACTIONS array, select a TRANSACTIONS[i], i is this RRC message type corresponding value in RRC_Message_Id_e.
(4) utilize the defined various operators of searching in top the 4th part, the TRANSACTIONS[i that is described as according to TS25.331 Section8.6.3.11] select an operator scheme (operation mode), comprise acceptance (accept it), refusal (Rejectit) or ignore (ignore it);
(5) in 4, select suitable operator in the defined various operators to TRANSACTIONS[i according to the operation mode in the abovementioned steps (4)] process.
Adopted above-mentioned 3G (Third Generation) Moblie terminal rrc layer to the method for managing signaling message transaction identifier, owing to wherein adopted static one dimension affairs array to realize the management of Transaction Identifier, and be designated as the type of message sign of signaling message under the element in this affairs array, include the operation information position corresponding with the number of Transaction Identifier in each element of this affairs array, thereby the storage space that will take still less records more operation information content, and to the access of the element of each affairs and revise also more convenient, so that RRC also is more prone to the maintenance of Transaction Identifier, so that operational process is efficient and convenient, highly effective, modification and attended operation are simply effective, stable and reliable working performance, the scope of application is comparatively extensive, for the development of 3G (Third Generation) Moblie terminal technology has been established solid foundation.
