Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method, system and equipment of accidental access response.
Background technology
In any one mobile communication system, all can relate to random access procedure.Its basic principle is roughly the same, but all has some small difference.General process all is network configuration by downlink signaling indication subscriber equipment this sub-district RACH (Random Access Channel, Random Access Channel) in broadcast channel; Subscriber equipment sends the request that inserts the employed parameter of request at random and insert at random to the network transmission according to this configuration decision; Network responds subscriber equipment after receiving this request, the successful access network of indication subscriber equipment.
In LTE (Long Term Evolution, Long Term Evolution net) network, subscriber equipment sends the parameter that inserts request at random to be had the signature of the temporal frequency resource at RACH channel place, access use at random and inserts transmitted power of request or the like at random.Wherein, the access request that different user devices sends on frequency resource at the same time can be used different signatures that this is inserted request at random and distinguish, and signing is 0-63.
Meeting need indicate subscriber equipment to carry out the uplink synchronous adjustment in response after network receives access request at random, in addition according to the difference that inserts reason, the content of carrying in the response also has difference, for example need to carry the resource of distributing up signaling in the access of the switching response, and need to carry distribution connection identifier or the like in the initial response that inserts.Certainly which subscriber equipment also needs to identify this response message simultaneously sends to.The sign that is used to distinguish different user devices promptly inserts temporal frequency resource and the signature that request sends at random.If subscriber equipment is not also waited until the response of network in a period of time after being sent in access request at random, with regard to the trial that inserts at random again.
In existing scheme, use different dispatchs to distinguish between the user of different time frequency resource, be not embodied in the response message.And rely on the different signature (each signature length is 6bit) that carries in the response message to identify with regard to needing for the accidental access response of the different user devices on the frequency resource at the same time, the structure of this sign is as shown in table 1 below:
Table 1:
| Information unit | Bit number |
| Signature | 6 |
| Connection identifier (optional) | 16 |
| Adjust synchronously | TA (concrete length is treated standardization) |
| Ascending resource distributes (optional) | UL-RA (concrete length is treated standardization) |
Wherein, TA (Time Advance, the time in advance) and UL-RA (Uplink Random Access, uplink random inserts) are for inserting required parameter.
Can certainly be incorporated in the response of a plurality of subscriber equipmenies in the same response message and send, this response message structure is as shown in table 2 below:
Table 2:
| Information unit | Bit number |
| The signature number that response is arranged | 6 |
| Signature 1 | 6 |
| Connection identifier 1 (optional) | 16 |
| Adjust 1 synchronously | TA (concrete length is treated standardization) |
| Ascending resource distributes 1 (optional) | UL-RA (concrete length is treated standardization) |
| Signature 2 | 6 |
| Connection identifier 2 (optional) | 16 |
| Adjust synchronously | TA (concrete length is treated standardization) |
| Ascending resource distributes 2 (optional) | UL-RA (concrete length is treated standardization) |
| ...... | ...... |
| Signature N | 6 |
| Connection identifier N (optional) | 16 |
| Adjust N synchronously | TA (concrete length is treated standardization) |
| Ascending resource distributes N (optional) | UL-RA (concrete length is treated standardization) |
When using this form, the length SUM of this response message is N * (16+6+TA+UL-RA)+6 as can be seen.Response to each subscriber equipment in the message all needs 6bit to identify, and does not clearly indicate for the signature that does not have response.Use the shortcoming of this method to be: the response for each subscriber equipment all needs 6bit, has wasted transfer resource; In addition, do not do clearly indication, make that the user of access failure could carry out access attempts again after the wait-for-response timer expiry at random, strengthened the time delay that inserts again for the signature that does not have response.

Embodiment
A kind of method of accidental access response may further comprise the steps as shown in Figure 1 in the embodiments of the invention one:
Step s101, will be at the same time on the frequency resource, a plurality of accidental access responses that insert request at random with different signatures are incorporated in the same accidental access response message, this accidental access response message is represented the response condition of each signature by default bitmap.
In this step, in response message, use bitmap to represent whether certain signature has response.Bitmap is the character string with specific format, and one or more (a plurality of bit) with bitmap represent for the response condition of each signature.When for example whether response being arranged with signature of a bit representation of bitmap in the response message, can represent not response with 0,1 expression has response; When perhaps representing the response condition of a signature with the multidigit of bitmap in the response message, can represent not only whether certain signature has response, can also represent the form that responds, during as the response condition of a signature of per 2 bit representations, can represent not respond with 00, have only synchronous adjustment message in the 01 expression response, existing synchronous adjustment message has the ascending resource distribution again in the 10 expression responses, 11 expressions comprise synchronous adjustment information simultaneously, and ascending resource distributes and connection identifier.
In response message, order and format permutation that each signature is represented according to bitmap in response, if promptly in the response message that comprises 5 signatures, with bitmap each the expression signature response, and in the bitmap signature of first correspondence for the signature of 1, second correspondence of signature for signature 2 ..., the signature of the 5th correspondence is signature 5, then in the response message behind the bitmap responses of different signatures put in order and also be signature 1, signature 2, signature 3, signature 4, signature 5.The length of bitmap is decided by the signature number that merges in response message on this temporal frequency resource, for example represent the response condition of all 64 signatures on the frequency resource at the same time in the response message and during with the response condition of the signature of each expression of bitmap, the length of bitmap is 64bit, and this moment, the structure of response message can be shown in 3:
