Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method, base station and terminal of obtaining extend information.
Background technology
Using TDMA (time division multiple access, Time Division Multiple Access) in the group system of mechanics of communication, one or more logic channels (time slot) on the needs physical channels of appointment (carrier frequency) are as TSCC (trunked base station control channel, Trunk Station Control Channel), when TSCC was activated, the channel device that carries this physical channel (carrier frequency) must be in continuous emission state.Send even without informational needs, receive the continuity of link pathfinding signaling, essential free time (Idle) frame of filling of all logic channels (time slot) on this physical channel (carrier frequency) in order to guarantee terminal.
In with DMR (digital mobile intercom, the DigitalMobile Ratio) agreement that adopts two time slot tdma transmission meanss, the air interface data transmission means of TSCC place physical channel (carrier frequency) as shown in Figure 1.In Fig. 1, red part is carried system's configuration informations such as two logic channels (time slot), sharing system identification code, register information unit and generalized slot counter; Yl moiety bearing system TSCC goes up the control signaling that sends; Blue portion carries non-TSCC goes up the business datum of transmission or the control signaling that non-special-purpose TSCC upward sends.
The principle of TDMA is that the time is divided into periodic frame (Frame), again each frame is divided into several slots to base station transmit signals, under regularly satisfied and synchronous condition, the base station can receive the signal of each portable terminal respectively and can not produce mixed disturbing in each time slot.Simultaneously, the signal that the base station is sent to a plurality of portable terminals all is arranged in order in the predetermined time slot and transmits, each portable terminal if in the time slot of appointment received signal, just can be in closing the signal on road the handle signal of issuing oneself distinguish and receive.By the principle of above-mentioned TDMA as can be known, equally have the ability to handle other data on the adjacent logic channel (promptly being time slot) in the control signaling of terminal on receiving TSCC.
The DMR agreement classifies as a kind of of data signaling with idle (Idle) frame, and the colour coding in its air interface structure (CC), data type (Data Type=Idle), error correcting code (FEC Parity) and sync pattern (SYNC) content need be consistent with other data signaling; That signaling content (Info) is filled is pseudo random number (Pseudo random bits).
By above prior art as can be known, the signaling content of idle (Idle) frame is unregarded, that is to say, in case it is idle (Idle) frame that the signaling process program detects the data type (Data Type) of signaling, its signaling content is exactly an irrelevant information, the signaling process program no longer continues to handle this frame data, and the handling process of this frame also just is through with.Since but this physical channel (carrier frequency) is carrying TSCC's, terminal must receive the information of this TSCC again all the time, also is lasting surely a reception for non-special-purpose TSCC or the signaling on the service logical channels (time slot) with carrier frequency.And non-generally speaking special-purpose TSCC is idle under the situation of non-a large amount of service data transmissions, and this just makes a large amount of bandwidth waste of generation in the signaling transmission course, thus the waste network transmission resource.

Step 303: the idle frame that extend information will have been filled in the base station sends to terminal.
The idle frame that the base station will have been filled Time of Day information again sends to terminal, particularly, the base station is with BPTC (the Block Product Turbo Code of DMR agreement regulation, polylith topology sign indicating number) (96,196) form carries out reprinting in signaling content (Info) field of idle (Idle) frame behind the code interleaving, and sends to terminal from eating dishes without rice or wine.
Step 304: terminal is carried out the deinterleaving decoding according to the BPTC form of DMR agreement regulation.
After terminal received the idle frame of base station transmission, at first BPTC (96, the 196) form according to DMR agreement regulation carried out the deinterleaving decoding.
Step 305: terminal is the time service data according to the signaling Context resolution of the idle frame information type that is expanded.
Terminal learns that according to data type (Data Type) field this frame is idle (Idle) frame, and the extend information type that solves according to signaling content (Info) (Extension Type) field learns that the data of this signaling bear are the time service data again.
Step 306: terminal goes out the temporal information of base station side by the format analysis of time service data.
Terminal goes out temporal information by the format analysis of time service data again, for example date, Hour Minute Second numerical value.
Further, terminal can also be calibrated the clock variable of self according to the temporal information that parses.
In the present embodiment, not only can realize saving the purpose of network transmission resource, can also realize clock synchronization base station and terminal, adopt present embodiment method can so that time accuracy error in 30ms.
When extend information was encryption key, the base station can be used for the decrypting process of all data at signaling content (Info) the field carrying encryption key of idle (Idle) frame after terminal receives under the air interface transmission means of encrypting.With reference to figure 4, in the inventive method embodiment three, realize that the method that the embodiment of the invention three is provided can may further comprise the steps:
Step 401: the encryption key filling mode of the signaling content of the described idle frame of making an appointment in base station and terminal both sides.
Extend information in the present embodiment is an encryption key, is encrypted as example with DES (Data EncryptionStandard, data encryption standard), and it is a kind of block encryption algorithm by IBM Corporation's development, serves as that grouping is encrypted data with 64.DES also is a symmetry algorithm simultaneously: what encryption and decryption were used is same algorithm.Its key length is 56 (because each the 8th all be used as parity check), and key can be 56 a number arbitrarily, and change arbitrarily the time.Des encryption is opposite with the unique order that is not both key of deciphering.If respectively take turns encrypted secret key is respectively K1, and the key that K2, K3......K16 decipher so is exactly K16, K15, K14......K1.
A kind of bearing mode of the actual in actual applications signaling inclusive segment to idle (Idle) frame can reference table 4 shown in, table 4 is the filling sample schematic diagram of idle frame, having defined 96 bit signaling contents in base station and end side, promptly is the data array of idle (Idle) frame signaling content carrying encryption key.
