Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of HS-SCCH method for channel allocation and device.
Background technology
Begin from Release5; Third generation co-operative project (3rd Generation Partnership Project; (High Speed Downlink Packet Access, HSDPA) technology is in order to provide the downlink grouped high-speed transfer of interface aloft 3GPP) the high speed downlink packet access to be provided.It is by high-speed downlink shared transmission channel (High Speed Downlink Shared Channel; HS-DSCH), high speed down sharing physical channel (High Speed Physical Downlink Shared Channel; HS-PDSCH), downlink high-speed shared control channel (Shared Control Channel for HS-DSCH; HS-SCCH; Hereinafter to be referred as SCCH) and shared indicating channel (Shared Information Channel for HS-DSCH, HS-SICH is hereinafter to be referred as SICH) interact and to realize.And existing agreement (Release 5) has following regulation for HS-SCCH and HS-SICH channel:
The SCCH channel is as the down control channel of auxiliary HS-DSCH channel; (Transmission Time Interval TTI) can monitor a plurality of SCCH channels (needing to monitor 4 SCCH channels down at most such as, single carrier) to each user continuously at each Transmission Time Interval; User for continuous scheduling; A TTI only monitors the SCCH channel that this TTI uses, and promptly for the user of continuous scheduling, only can use a fixing SCCH channel;
The SICH channel is as the ascending control channel of auxiliary DSCH channel; Specify in advance through signaling with the corresponding relation of SCCH channel; And can not carry out dynamic-configuration; The corresponding relation that is SICH channel and SCCH channel is bound when setting up, and in the life cycle of two channels, effectively and not allows to carry out any change; The uplink capacity that the employed SICH channel of user receives this user limits, and promptly the user can only use some to the SCCH/SICH channel that uplink capacity supports.
Simultaneously; In the HSDPA system of the Node of reality B; The SCCH channel of a CU and other physical resource that takies (such as time slot, code channel with process etc. such as stop, below refer in particular to all physical resources beyond the SCCH channel with " other physical resource ") be in a minute timing, is two prerequisite, result's paradox each other again each other; Promptly have only distributed available SCCH channel to this user after, distribute other physical resource could for this user; Simultaneously, also have only to this user and distributed other physical resource, distribute the SCCH channel could for this user.If at first the user is distributed the SCCH channel, but distribute other physical resource failure, tend to cause this SCCH channel also can't distribute to other user; If at first this user is distributed other physical resource, if the failure of SCCH channel allocation, other physical resource that rollback distributes is the process of a complicacy, and needs to consume great amount of time, will be to the HSDPA system deleterious impact of Node B.
In sum, the distribution of SCCH channel distributes the following problem that mainly faces at present:
1, concerning the SCCH channel had user's (user such as continuously scheduling can only use same SCCH channel and receive the restriction of user's uplink capacity can only use several specific SCCH channels) of specific (special) requirements, the user that dispatching priority is high can't reasonably be assigned to available SCCH channel and not seize this type special user's SCCH channel;
2, SCCH channel and other physical resource can't be accomplished the distribution that the two can both be correct, and bring overcharge in a minute timing meeting to system, and all available SCCH channels can not be fully utilized when realizing simultaneously.
To this problem, the HSDPA system of existing Node B adopts approximate processing in order to reduce the complexity of realization more, promptly allows seizing with non-of SCCH channel to make full use of; Handle even so and inserting under the less situation of user, little to the throughput of system and each user's influence; But when a plurality of users inserted, with having a strong impact on the quality of services for users of being seized, and the performance of the system of giving was brought adverse influence.

Embodiment
Basic thought of the present invention is the result according to the dispatching priority ordering; Take out the plurality of adjacent user from high to low successively and form sliding window; And each user that only possibly handle in the window when user in handling window fails, confirms that again window is long; And sliding window, carry out the processing of next window; Like this, when the number of users in window was not more than the number of available SCCH channel, if promptly the interior user of window does not have specific (special) requirements to the SCCH channel, then each user can be assigned to an available SCCH channel.
Therefore, the invention provides a kind of HS-SCCH method for channel allocation, this method comprises:
A, confirm the original position of sliding window length and window in proper order according to user's dispatching priority;
B, for the user in the window distributes HS-SCCH channel and other physical resources, when distributing failure, return execution in step A and confirm length of window and original position again.
Concrete, understand the present invention program better in order to make those skilled in the art person, the present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 shows the flow process of the inventive method embodiment.As shown in Figure 1, the present invention includes:
Step 101: confirm the length and the original position of sliding window in proper order according to user's dispatching priority, when length of window is 0, end process;
Concrete, the length of at first definite window;
In the HSDPA system, in order to improve the mobile packet data transmittability, dispatching algorithm commonly used mainly contains three kinds: maximum cutting done than algorithm, repeating query algorithm and direct ratio fair algorithm; And adopt the sort of algorithm all can the user of needs scheduling to be sorted; In embodiments of the present invention, the result according to the dispatching algorithm ordering from high to low, takes out the plurality of adjacent user successively and handles, and several users of taking-up have formed window, and the length L of window is user's number, wherein comprises and comprise several kinds of situation:
When available HS-SCCH channel number is not less than current number of users of supply dispatching, the number of users of the length L value of sliding window for can supply dispatching;
When available HS-SCCH channel number during less than current number of users of supply dispatching, the length L value of sliding window is available HS-SCCH channel number;
For example: if current system can with the HS-SCCH channel number be 4, and have 2 users to participate in scheduling, the length L of sliding window=2 so;
If current system can with the HS-SCCH channel number be 3, and have 4 users to participate in scheduling, the length L of sliding window=3 so;
But no matter under the above-mentioned the sort of situation, when the length L value of sliding window is 1, jumps directly to step 102 and handle; When the length L value of sliding window is 0, then finish the processing of the inventive method embodiment channel allocation.
Then, sliding window is positioned, confirm the original position of sliding window;
When for the first time the user being handled, the user that dispatching priority is the highest gets L user as the user in the sliding window successively as the original position of sliding window;
The original position of confirming sliding window also should comprise the reorientation under the following several kinds of situation:
1. work as subsequent treatment and the situation that the user distributes failure only occurs:
Suppose that K user distributes failure in the sliding window; If this moment K=1; The user who promptly distributes failure is the available minimum user of HS-SCCH channel number, then navigates to K+1 user to the original position of sliding window, promptly with K the next user that the user is adjacent; If this moment K＞1; Then keep the original position of sliding window constant; And recomputate the length L of sliding window according to the method in the length of window step of confirming; Get L user successively according to the scheduling order behind the user who rejects above-mentioned distribution failure then, confirm that at last sliding window carries out subsequent treatment;
Concrete is as shown in Figure 2, supposes length L=3 of definite for the first time sliding window, has 5 users that can supply dispatch; After having confirmed sliding window for the first time; When user 1 takes place to distribute failure in subsequent treatment, carry out the first time and slide, user 2 is orientated as the original position of sliding window; When UE2 distributes failure, carry out the second time and slide, user 3 is orientated as the original position of sliding window; Follow-up slip is similar; At last user 5 is orientated as the original position of sliding window, the length of window L=2 that confirm this moment; In this case, the user before the window is the user who distributes failure, and when sliding for the third time, the UE1 of window front, UE2, UE3 are the users that failure takes place to distribute;
2. when subsequent treatment exists the user to distribute failure simultaneously and distributes case of successful:
Suppose that K user distributes failure in the sliding window; If K=1; Then the original position of sliding window is navigated to M user, wherein M ∈ [K+1, L]; And M is first user that need participate in epicycle channel and resource distribution in the dispatching priority sequencing queue, promptly removes K user and dispatches the highest user of priority outward; If K＞1; Then the original position of sliding window is navigated to M user; This moment N ∈ (1, L) and M be first user that need participate in epicycle channel and resource distribution in the dispatching priority sequencing queue, also be and remove K user and dispatch the highest user of priority outward; Recomputate the length L of sliding window according to the method in the length of window step of confirming then; Dispatching priority clooating sequence behind the user who distributes the user of failure according to rejecting again and be allocated successfully is got L user successively, confirms that at last sliding window carries out subsequent treatment;
Concrete is as shown in Figure 3, and length L=3 of the sliding window that same hypothesis is confirmed for the first time have 5 users that can supply dispatch; User 2 distributes failure in subsequent treatment; Then carry out the window slip first time, this moment, the original position of sliding window was constant, and length of window remains L=3; But sliding window has been rejected user 2, forms new sliding window by user 1, user 3 and user 4; Follow-up slip treated is similar, is not described in detail in this.
In addition, it should be noted that in the present embodiment " user distributes failure " is meant that this user's preassignment HS-SCCH channel is failed in the subsequent treatment, perhaps other physical source distributing failure of this user; " user distributes success " is meant that the interior user of window distributes case of successful of HS-SCCH channel and other physical resource in the subsequent treatment; And " preassignment " is meant that hypothesis is given certain user the HS-SCCH channel allocation earlier, if other physical source distributing success then uses to this HS-SCCH channel final assignment this user; If this HS-SCCH channel is then regained in other physical source distributing failure.
Step 102: for the user in the window distributes HS-SCCH channel and other physical resources, and judge whether to exist the user who distributes failure, if exist then return execution in step 101, otherwise end process;
Concrete, in embodiments of the present invention,, the user in the sliding window can adopt other distribution methods of the prior art for distributing HS-SCCH channel and other physical resources, be not described in detail in this;
In addition, also can adopt to sliding window mechanism the user in the sliding window is carried out the method for channel and physical source distributing, as shown in Figure 4, specific as follows:
Step 201: obtain the user can use in the sliding window HS-SCCH channel list and channel number, show that when this number is 0 this user distributes failure, then finish the allocation process in the window;
After sliding window was confirmed, the user for dispatching continuously in the window when available HS-SCCH channel number N is 1, no longer considered the influence of other any restrictive condition to the N value, and this moment, N was actual available HS-SCCH channel number; And for the user of first participation scheduling or the user of discontinuously dispatching; The N value is got the number of this user current available all HS-SCCH channels when participating in this scheduling; The HS-SCCH channel number of this moment is under some kinds of restrictive conditions (such as the user uplink capabilities limits etc.); This user is current operable, and is the HS-SCCH channel number that system can provide use; Simultaneously, in the process of total channel number that the user can use in the statistics sliding window, note the HS-SCCH channel that each user can use, form the HS-SCCH channel list that the user can use.
But when the user that obtains of statistics can with HS-SCCH channel number when being 0, show that then follow-up user's distribution can fail, promptly finish the allocation process in the window this moment, returns execution in step 101, again window positioned and confirm length of window.
Step 202: the user is sorted according to major-minor priority;
After obtaining the HS-SCCH channel number that the user can use and forming the HS-SCCH channel list that the user can use, the HS-SCCH channel number N that can use with the user is as the master-priority standard: the N value is more little, shows that master-priority is high more; Simultaneously with user's the dispatching priority auxilliary priority P as the user: user's dispatching priority is high more, and then auxilliary priority is high more; With user's the master-priority and the height order of auxilliary priority the user in the window is sorted;
In sequencer procedure, sort with the master-priority standard earlier, when master-priority N is identical, with auxilliary priority P the identical user of N value is sorted again.
Step 203: the user to after the ordering carries out the preassignment of HS-SCCH channel, if exist the user to distribute failure, then finishes the allocation process in the window;
Set up a HS-SCCH channel list 1 of having distributed, be used for writing down the HS-SCCH channel that preassignment is gone out; In the pre-allocation process of channel, in the window according to first user in the major-minor prioritization formation, directly give its first available HS-SCCH channel of this user's preassignment; For in the window according to the subsequent user in the major-minor prioritization formation; The HS-SCCH channel that deletion front user has taken from its available HS-SCCH channel list is pre-assigned to this user to first the available HS-SCCH channel in the available HS-SCCH channel list of remainder then; If distribute successfully, then in table 1, write down this HS-SCCH channel; If distribute failure, then empty table 1, return execution in step 101 then, again window is positioned and confirm length of window; If all users distribute success in the window, then execution in step 204.
Step 204: the user in the window is carried out the distribution of other physical resources,, then finish the allocation process in the window if exist the user to distribute failure;
Set up a user list 2 that has become other physical resource of the distribution of work, be used for writing down the user of other physical resource that become the distribution of work; To the user of preassignment channel in the step 203; According to dispatching priority P order it is carried out the distribution of other physical resource,, then no longer this user is distributed if write down this user other physical resource that become the distribution of work in the user list 2; Otherwise, give this user resource allocation; If distribute successfully, then in table 2, note this user; If exist a user to distribute failure, then empty table 1 reservation table 2, and do not reclaim in the table 2 corresponding other physical resource that has distributed of user of record, return execution in step 101 then, again window is positioned and confirm length of window;
In addition; It should be noted that the operation that empties table 1 and reservation table 2 is not what fix; It can realize selecting according to concrete design, if for example user's storage is stored according to the order of dispatching priority P, the P value is unique; Then do not empty table 2 for not influence of subsequent processes, can not empty table 2 this moment.
Step 205: give the successful user of physical source distributing with preallocated channel final assignment;
If in step 204, all users have become other physical resources of the distribution of work in the sliding window, then give corresponding user each preallocated HS-SCCH channel final assignment, accomplish the distribution of channel;
In addition; Can also be after becoming other physical resources of the distribution of work for a user, if this user's master-priority N is 1, promptly master-priority is the highest; Then can directly distribute to this user to the preallocated HS-SCCH channel of this user uses; The current available HS-SCCH channel list of update system simultaneously, and from the scheduling formation, reject this user, this user's batch operation accomplished.
Based on above-mentioned thought, the present invention also provides a kind of HS-SCCH channel dividing arrangement, and this device comprises: windows units 501 and allocation units 502;

In addition, said windows units 501 also can comprise fixed-size location 5011 and positioning unit 5012; The number of users that said fixed-size location 5011 can supply be dispatched according to the HS-SCCH channel number is confirmed the length of sliding window; When available HS-SCCH channel number is not less than current number of users of supply dispatching, confirm the number of users of length L value for can supply dispatching of sliding window; When available HS-SCCH channel number during less than current number of users of supply dispatching, the length L value of confirming sliding window is available HS-SCCH channel number;
Said positioning unit 5012 is confirmed the original position of sliding window according to user's dispatching priority; When for the first time the user being handled; Positioning unit 5012 user that dispatching priority is the highest gets L user as the user in the sliding window successively as the original position of sliding window.
Said windows units 501 also can further comprise reorientation unit 5013; Said reorientation unit 5013 is used to receive the assignment information that allocation units send; When receiving only the information of distributing failure; Whether the user who judges this distribution failure is the highest user of master-priority, if then the original position with window is decided to be the next user adjacent with this user; Otherwise; Keep the original position of window constant; And other users are confirmed length of window again according to the dispatching priority order, and get L user successively according to the scheduling order behind the user who rejects above-mentioned distribution failure then, definite at last sliding window carries out subsequent treatment; When receiving distribution failure and information of successful; Then the original position with window is decided to be the highest user of dispatching priority among other users; Then other users are confirmed length of window again according to the dispatching priority order; Get L user successively according to the dispatching priority clooating sequence after rejecting the user who distributes failure and distributing successful user again, confirm that at last sliding window carries out subsequent treatment.
Said allocation units 502 are used to said windows units 501 definite interior users of window and distribute HS-SCCH channel and other physical resources, when distributing the situation of failure, indicate said windows units 501 length and the original position of definite window again.
