Fig. 1 is the realization flow schematic diagram of cut-in method of the present invention.
Embodiment
Main thought of the present invention is: divide one or more functional domains at different business, and the SYNC_UL sign indicating number is assigned in the difference in functionality territory; User terminal according to the attribute of self institute's requested service, is chosen corresponding SYNC_UL sign indicating number and is carried out uplink synchronous when inserting in the difference in functionality territory.
Accordingly, network side can adopt different strategies to handle for the SYNC_UL sign indicating number in the corresponding difference in functionality territory of receiving.Such as: under the message trunking pattern of TD-SCDMA Digital Clustering, by the SYNC_UL sign indicating number is divided into the difference in functionality territory, network can be distinguished dispatch call control channel reserve requests and Dedicated Traffic Channel reserve requests, guarantees that the half-duplex dispatch call has access speed and right of speech conversion speed faster.
In addition, the present invention also is provided with the access priority that inserts at random, and the division of set access priority is associated with the uplink synchronous code sequence number, and then can be according to the real-time degree or the significance level of business need, the uplink synchronous code of the different access priorities of correspondence is distributed to the difference in functionality territory, thereby guarantee that advanced level user is with the quick connecting system of higher probability.Such as: there are eight available uplink synchronous codes 0 to 7 sub-district, supposes that the access priority of uplink synchronous code 0 is the highest, and uplink synchronous code 1 and 2 access priority are time high, and the access priority of uplink synchronous code 5 to 7 is minimum.Suppose that present system can provide three class business--professional A, professional B and professional C, the real-time that wherein professional A requires is the highest, the real-time that professional C requires is minimum, three functional domains of system divides--functional domain a, functional domain b and functional domain c, the corresponding professional A of difference, professional B and professional C, for the access rate that guarantees that responsible consumer is higher, when distributing uplink synchronous code for the difference in functionality territory, just uplink synchronous code 0 is distributed to functional domain a, uplink synchronous code 1 and 2 is distributed to functional domain b, uplink synchronous code 5 to 7 is distributed to functional domain c, and so, user terminal is when requested service A, will provide the uplink synchronous code 0 that concerns selection function territory a correspondence according to business, because the access priority of uplink synchronous code 0 is the highest, so this user terminal can preferential connecting system.
The specific implementation flow process that user terminal of the present invention inserts may further comprise the steps as shown in Figure 1:
Step 101: divide one or more functional domains at different business, and the SYNC_UL sign indicating number is assigned in the difference in functionality territory.
Usually, being distributed in when carrying out the network planning of the division of functional domain and SYNC_UL sign indicating number finished, and therefore, network side and user terminal all can directly be known between functional domain and the business, the corresponding relation between functional domain and the SYNC_UL sign indicating number.Here, for each sub-district, the described SYNC_UL sign indicating number is assigned in the difference in functionality territory is meant: all SYNC_UL sign indicating numbers that respective cell is comprised are divided in the difference in functionality territory, and the corresponding relation between functional domain and the SYNC_UL sign indicating number can be stored in user terminal and network side respectively.Such as: current division has three functional domains, and there are 16 SYNC_UL sign indicating numbers each sub-district, so, just 16 SYNC_UL sign indicating numbers is assigned in three functional domains, and the SYNC_UL yardage that each functional domain distributes can be determined arbitrarily.
Step 102: during the user terminal connecting system, determine functional domain, in all SYNC_UL sign indicating numbers of determined functional domain correspondence, choose one wantonly again according to the business of self asking.
Step 103: utilize selected SYNC_UL sign indicating number to carry out uplink synchronous.
Like this, after network side is received the SYNC_UL sign indicating number, just can be according to the corresponding relation between SYNC_UL sign indicating number and the functional domain, between functional domain and the business, determine the business that the user terminal of current access is asked, and then select for use suitable processing policy that this business is handled.
For the access rate that guarantees that responsible consumer is higher, can further include in the step 101: access priority is set, and with access priority divide with the uplink synchronous code sequence number between be associated, the corresponding relation between access priority and the SYNC_UL sign indicating number sequence number can be stored in user terminal and network side respectively.Accordingly, when uplink synchronous code is assigned to the difference in functionality territory, according to the significance level of the corresponding business of height and each functional domain institute of the corresponding access priority of uplink synchronous code sequence number, the uplink synchronous code that access priority is high is distributed to the functional domain of important service correspondence.
Be example with the TD-SCDMA digital cluster system below, describe the specific implementation of the inventive method in detail.
In actual applications, the division of functional domain can have multiple different form, and same, the allocative decision that the SYNC_UL sign indicating number is assigned to the difference in functionality territory also has multiple.Such as: the TD-SCDMA digital cluster system is supported urgent call, half-duplex dispatch call, three kinds of business of full duplex call, so, can divide three functional domains: functional domain A, functional domain B and functional domain C, wherein, the corresponding urgent call of functional domain A, the corresponding half-duplex dispatch call of functional domain B, the corresponding full duplex call of functional domain C, accordingly, the SYNC_UL sign indicating number of the functional domain A correspondence SYNC_UL sign indicating number that is used for urgent call, the functional domain B correspondence SYNC_UL sign indicating number that is used for half-duplex dispatch call, functional domain C correspondence is used for full duplex call.If full duplex call and half-duplex dispatch call adopt unified processing policy, also can only divide two functional domains: functional domain a and functional domain b, wherein, the corresponding urgent call of functional domain a, the corresponding half-duplex dispatch call of functional domain b, accordingly, the SYNC_UL sign indicating number of the functional domain a correspondence SYNC_UL sign indicating number that is used for urgent call, functional domain b correspondence is used for half-duplex dispatch call and full duplex call.Generally, because the available SYNC_UL sign indicating number number of each sub-district is limited, and consider the amount of calculation of uplink synchronous, functional domain is difficult for dividing too much.
For each functional domain, can also further divide the subfunction territory according to actual business requirement.Such as: in the TD-SCDMA digital cluster system, comprise different cluster modes: message trunking pattern, transmission trunking pattern.With the situation of dividing three functional domains is example, when handling the half-duplex dispatching calling service, under the transmission trunking pattern, because the signalling interactive process of right of speech conversion do not carrying out on the Dedicated Traffic Channel but carry out on the dispatch call control channel, so do not need to divide the subfunction territory; But under the message trunking pattern, because the future mechanism that system adopts on dispatch call control channel and Dedicated Traffic Channel is different, so just need do further division to the SYNC_UL sign indicating number of functional domain B and correspondence thereof.
Specifically, for the reservation of distinguishing the dispatch call control channel and the reservation of Dedicated Traffic Channel, functional domain B further can be divided into two sub-functional domains: functional domain B1 and functional domain B2, wherein, the foundation that is used to make a call of the SYNC_UL sign indicating number of functional domain B1 correspondence, the SYNC_UL sign indicating number of functional domain B2 correspondence is used to initiate the right of speech conversion request.In this case, user terminal is just chosen one and is carried out uplink synchronous if the foundation that makes a call is asked from the SYNC_UL sign indicating number of functional domain B1 correspondence; The SYNC_UL sign indicating number from functional domain B1 that network side will be received is regarded the reserve requests of user terminal to the dispatch call control channel as; If user terminal is preengage successfully, network side will be finished up to call setup for this user reserves the dispatch call control channel; Behind call setup, network side will distribute a Dedicated Traffic Channel to the calling and called both sides, follow-up carrying out right of speech when conversion, and relevant signaling is transmitted on Dedicated Traffic Channel.User terminal is just chosen one and is carried out uplink synchronous if initiate the right of speech conversion request from the SYNC_UL sign indicating number of functional domain B2 correspondence.Network side will finish up to the right of speech transfer process for this user reserves Dedicated Traffic Channel after receiving SYNC_UL sign indicating number from functional domain B2.
For the situation of dividing two functional domains, functional domain is divided the methodological principle and the network side in subfunction territory and received that the handling process behind the SYNC_UL sign indicating number is identical with the situation of dividing three functional domains, that is: during the half-duplex dispatching calling service under realizing the message trunking pattern, functional domain b further is divided into functional domain b1 and functional domain b2.Different is, the corresponding half-duplex dispatch call of functional domain b and two kinds of business of full duplex call adopt the SYNC_UL sign indicating number of different subfunctions territory correspondence respectively according to the difference request when initiating the half-duplex dispatch call; And when initiating full duplex call, the SYNC_UL sign indicating number of function of use territory b1 correspondence only.
Under the situation of dividing the subfunction territory, user terminal is also further determined the subfunction territory according to self current state of living in.To divide three functional domains is example, certain user terminal requests be the half-duplex dispatching calling service, then determine that according to self institute's requested service kind functional domain is functional domain B, if the current state of living in of this user terminal is called out for setting up, then user terminal further determines that according to self current state of living in functional domain is subfunction territory B1, afterwards, just in the SYNC_UL sign indicating number of functional domain B1 correspondence, choose one and carry out uplink synchronous.
No matter be the situation of three functional domains or the situation of dividing two functional domains of dividing, when network side was received a SYNC_UL sign indicating number from functional domain A, if dispatch call control channel free time this moment, then network side was by normal urgent call flow processing; If this moment, the dispatch call control channel was occupied; because the access priority of the SYNC_UL sign indicating number of functional domain A correspondence is higher than functional domain B; so network side will suspend or remove the current signaling process of handling, and the user terminal of the dispatch call control channel being distributed to the SYNC_UL sign indicating number of sending function territory A correspondence uses.So, can guarantee the preferential connecting system of user terminal of high priority.
Among the present invention, described division with access priority is associated with the sequence number of SYNC_UL sign indicating number multiple dividing mode can be arranged, and specifically divides according to actual needs to get final product.Give an example supposed the TD-SCDMA system definition that adopted 16 SYNC_DL sign indicating numbers, SYNC_DL sign indicating number of each cell allocation, corresponding 16 the SYNC_UL sign indicating numbers of each SYNC_DL sign indicating number, be one group, as shown in table 1, table 1 is the mapping table of SYNC_UL sign indicating number and SYNC_DL sign indicating number.Suppose every group the SYNC_UL sign indicating number by the corresponding from small to large access priority of sequence number successively from high to low, such as: sequence number is that the access priority of 0 SYNC_UL sign indicating number is the highest in the group 1, the access priority of the SYNC_UL sign indicating number of other sequence number successively decreases successively, sequence number is that the access priority of 15 SYNC_UL sign indicating number is minimum, and other access priority order of respectively organizing the SYNC_UL sign indicating number is identical with group 1.
| The SYNC_DL code character | SYNC_DL sign indicating number sequence number | SYNC_UL sign indicating number sequence number |
| Group 1 (sub-district 1) | 0 | 0...15 |
| Group 2 (sub-districts 2) | 1 | 16...31 |
| ... | ... | ... |
| Group 16 (sub-districts 16) | 15 | 240...255 |
Table 1
To organize 1 is example, when dividing three functional domains--functional domain A, functional domain B and functional domain C, corresponding urgent call respectively, half-duplex dispatch call, three kinds of business of full duplex call, and functional domain B further is divided into two sub-functional domains--functional domain B1 and functional domain B2, being respectively applied for when making a call foundation and initiating the right of speech conversion request, if the TD-SCDMA digital cluster system is to handle the half-duplex dispatch call, distribute 1 SYNC_UL sign indicating number then for functional domain A, functional domain B distributes 12 SYNC_UL sign indicating numbers, and functional domain C distributes 3 SYNC_UL sign indicating numbers.Because the urgent call of functional domain A correspondence needs preferential the access, the half-duplex dispatch call takes second place, be full duplex call at last, therefore, be that 0 SYNC_UL sign indicating number is distributed to functional domain A with sequence number, sequence number is that 1 to 12 SYNC_UL sign indicating number is distributed to functional domain B, sequence number is that 13 to 15 SYNC_UL sign indicating number is distributed to functional domain C, so, can realize the fast processing of urgent call, guarantee that urgent call has the shortest turn-on time.
Further, in 12 SYNC_UL sign indicating number mean allocation to two sub-functional domains with functional domain B correspondence, corresponding 6 the SYNC_UL sign indicating numbers of functional domain B1, promptly sequence number is 1 to 6 SYNC_UL sign indicating number; Corresponding 6 the SYNC_UL sign indicating numbers of functional domain B2, promptly sequence number is 7 to 12 SYNC_UL sign indicating number.Certainly, can not divide equally in the practical application yet.Though divide from sequence number, the access priority of functional domain B1 is higher than functional domain B2, but, therefore the access priority of functional domain B1 and functional domain B2 can be considered as equating because system can handle two simultaneously respectively from the SYNC_UL sign indicating number of functional domain B1 and functional domain B2 in a frame.Table 2 is the functional domain dividing condition of each SYNC_UL sign indicating number in the group 1, and the division of other each group is similar with group 1.
Table 2
According to the distribution method shown in the table 2, urgent call has the highest processing priority, secondly is the half-duplex dispatch call, is full duplex call at last.In the TD-SCDMA digital cluster system, can be the SYNC_UL sign indicating number of a little sequence number among advanced level user or responsible consumer fixed allocation functional domain B1 and the functional domain B2, as 1 and 7, to guarantee that advanced level user or responsible consumer are with the quick connecting system of higher probability.Rudimentary user or domestic consumer can the bigger SYNC_UL sign indicating numbers of shared a plurality of sequence numbers, such as: sequence number is 2 to 6 SYNC_UL sign indicating number among the B1 of distribution function territory, and sequence number is 8 to 12 SYNC_UL sign indicating number among the functional domain B2.Like this, can improve the service efficiency of SYNC_UL sign indicating number.
When dividing two functional domains--functional domain a and functional domain b, difference corresponding urgent call, half-duplex dispatch call and full duplex call, and functional domain b further is divided into two sub-functional domains--functional domain b1 and functional domain b2, being respectively applied for when making a call foundation and initiating the right of speech conversion request, division methods is similar, such as: the SYNC_UL number of codes that can distribute each functional domain according to the scheme shown in the table 3, table 3 is the functional domain dividing condition of each SYNC UL sign indicating number in the group 1, and the division of other each group is similar with group 1.
Table 3
Certainly, in actual applications, can also set the principle of correspondence of other access priority and SYNC_UL sequence number, be that the access priority of 0 SYNC_UL sign indicating number is minimum such as: sequence number, and the access priority of the SYNC_UL sign indicating number of other sequence number increases progressively or the like successively.
If in a uplink pilot time slot, receive a plurality of from functional domain B1/b1 the SYNC_UL sign indicating number or receive a plurality of SYNC_UL sign indicating numbers from functional domain B2/b2, network side selects the highest SYNC_UL sign indicating number of access priority to handle, if access priority is all identical, then select a SYNC_UL sign indicating number to handle at random.If not only received from the SYNC_UL sign indicating number of functional domain B1/b1 in a uplink pilot time slot but also receive SYNC_UL sign indicating number from functional domain B2/b2, then network side selects a highest SYNC_UL sign indicating number of access priority to handle from two functional domains respectively.
For realizing said method, the present invention can be provided with the uplink synchronous code determining unit in user terminal, be used for optional one of the uplink synchronous code of functional domain correspondence under the current request business, and selected uplink synchronous code delivered to the uplink synchronous transmitting element of user terminal; Store the corresponding relation of functional domain and uplink synchronous code in the described uplink synchronous code determining unit.In the uplink synchronous code determining unit, also further store the corresponding relation between subfunction territory and the uplink synchronous code, and the corresponding relation between access priority and the uplink synchronous code sequence number.
At network side, professional determining unit can be set in network side apparatus, be used for determining the business that the user terminal of current access is asked according to the functional domain of the uplink synchronous code correspondence of being received, and with the uplink synchronous code response unit of determined service announcements network side; Store the corresponding relation of functional domain and uplink synchronous code in the described professional determining unit.In professional determining unit, also further store the corresponding relation between subfunction territory and the uplink synchronous code, and the corresponding relation between access priority and the uplink synchronous code sequence number.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
