Step 204, the carrying request that does not receive for step 202 are distributed bandwidth, determine the resource allocation failure, preferably, and can corresponding feedback bandwidth application failure;
Step 205 is from current available bandwidth B 2Distribute the bandwidth B that comprises in the described carrying request for described carrying request among the _ avail 2_ need determines the resource allocation success, at this moment the B of dedicated bandwidth of GSM 2_ used is updated to B 2_ used=B 2_ used+B 2_ need, preferably, message that can corresponding feedback bandwidth application success;
Step 206, with step 202 side by side, receive the user for after the business of using the gsm communication standard being used to of sending ask to revise the carrying request of bandwidth, according to total transmission bandwidth B, GSM and the corresponding respectively special-purpose bandwidth reserved B of TD-SCDMA 2, B 3, the bandwidth B used of GSM 2The bandwidth B that _ used and TD-SCDMA have used 3The former bandwidth B that takies of this user that comprises in _ used and the carrying request that receives 2The new bandwidth B that _ a and request are revised 2_ b determines to discharge former occupied bandwidth B 2The current available bandwidth B of GSM behind the _ a 2_ avail;
Particularly, B 2_ avail=B-B 2_ used-MAX (B 3, B 3_ used)+(B j_ a-B j_ b).
Step 207, the current available bandwidth B of the GSM that determining step 206 is determined 2The new bandwidth B whether _ avail revises less than the request that comprises in the carrying request that receives 2_ b is if enter step 208, otherwise enter step 209;
Step 208, the carrying request that does not receive for step 206 are distributed bandwidth, determine the resource allocation failure, preferably, and can corresponding feedback bandwidth application failure;
Step 209 is from current available bandwidth B 2The new bandwidth B of distributing the request modification that comprises in the described carrying request among the _ avail for described carrying request 2_ b determines the resource allocation success, at this moment the B of dedicated bandwidth of GSM 2_ used is updated to B 2' _ used=B 2_ used+B 2_ b-B 2_ a;
Step 210, with step 202, step 206 side by side, after being used to of receiving that the user of the business of using the gsm communication standard sends ask to discharge the carrying request of bandwidth, the former bandwidth B that takies that comprises in the releasing bearing request 2_ a, after the release bandwidth, the bandwidth B that the gsm communication standard has been used 2_ used is updated to B 2' _ used=B 2_ used-B 2_ a.
Preferably, when being carrying request distribution bandwidth in above-mentioned steps 205, step 209, specifically can distribute bandwidth according to the arbitrary strategy in the following strategy:
Strategy one: at the available bandwidth B of GSM standard 2The special-purpose bandwidth reserved B that had both comprised GSM among the _ avail 2, comprise common bandwidth B again pThe time, preferentially from B 2Common bandwidth B among the _ avail pIn distribute the bandwidth B that comprises in the described carrying request for described carrying request 2_ need or B 2_ b after the common bandwidth in available bandwidth has been assigned with, distributes bandwidth for the carrying request again from the special-purpose bandwidth reserved of GSM;
Strategy two: at the available bandwidth B of GSM standard 2The special-purpose bandwidth reserved B that had both comprised GSM among the _ avail 2, comprise common bandwidth B again pThe time, preferentially from the special-purpose bandwidth reserved B of GSM 2In be that described carrying request distributes bandwidth, after the special-purpose bandwidth reserved of the GSM in available bandwidth has been assigned with, from the common bandwidth that available bandwidth comprises, be carrying request distribution bandwidth again;
Strategy three: at the available bandwidth B of GSM standard 2The special-purpose bandwidth reserved B that had both comprised GSM among the _ avail 2, comprise common bandwidth B again pThe time, and send described carrying requesting users when the specific user, from B 2Special-purpose bandwidth reserved B among the _ avail 2In distribute the bandwidth B that comprises in the described carrying request for described carrying request 2_ need or B 2_ b;
At B 2The special-purpose bandwidth reserved B that had both comprised GSM among the _ avail 2, comprise common bandwidth B again pThe time, and send described carrying requesting users when the specific user, from B 2Common bandwidth B among the _ avail pIn distribute the bandwidth B that comprises in the described carrying request for described carrying request j_ need or B 2_ b.
Preferably, in step 203, the current available bandwidth B of GSM that determines at determining step 202 2Whether _ avail distributes bandwidth B less than the request that comprises in the carrying request that receives 2During _ need, also should consider transport overhead, i.e. the current available bandwidth B of GSM 2Whether _ avail is less than B 2The summation of _ need and transport overhead.
Preferably, can also distinguish the different business in each communication standard further, promptly be the foundation of distributing with the business, and detailed process is as follows:
At first from total transmission bandwidth B, mark off the first professional corresponding special-purpose bandwidth reserved B in the GSM standard 21, the second professional corresponding special-purpose bandwidth reserved B 22, and mark off the 3rd professional corresponding special-purpose bandwidth reserved B in the TD-SCDMA standard 31, the 4th professional corresponding special-purpose bandwidth reserved B 32
The follow-up user of receiving for use in the gsm communication standard first professional sends be used to ask to distribute the carrying request of bandwidth after, according to the 3rd business among first business among total transmission bandwidth B, the GSM, second business and the TD-SCDMA, the 4th professional special-purpose bandwidth reserved B of correspondence respectively 21, B 22, B 31, B 32, and the bandwidth B used of first business among the GSM, second business 21_ used, B 22The bandwidth B that the 3rd business among _ used and the TD-SCDMA, the 4th business have been used 31_ used, B 32_ used determines the first professional current available bandwidth B among the GSM 21_ avail:
B 21 _ avail = B - B 21 _ used - ΣMAX ( B 21 , B 21 _ used ) - Σ i = 1,2 MAX ( B 3 i , B 3 i _ used )
Wherein, first summation number can be extended in the GSM standard the professional corresponding bandwidth reserved of other except that first business and occupied bandwidth peaked summation in the two, and second summation number can be extended to bandwidth reserved and occupied bandwidth peaked summation in the two of each business correspondence of other standards.
Determine the first professional current available bandwidth B in the GSM standard 21Behind _ the avail, can adopt with the similar method of step 203～step 205, step 207～step 209 and distribute bandwidth resources.
In the reality, in step 203～205, step 207～209, when distributing bandwidth resources, also should consider transport overhead, judge promptly whether the current available bandwidth of determining of GSM standard distributes bandwidth B less than the request that comprises in the carrying request that receives 2_ need and transport overhead sum, judge the new the bandwidth B whether current available bandwidth of GSM standard behind the former occupied bandwidth of release determine is revised less than the request that comprises in the carrying request that receives 2_ b and transport overhead sum.
In the present embodiment, take too much transfer resource for fear of a kind of communication standard, at first be respectively every kind of communication standard and all divided corresponding special-purpose bandwidth reserved, special-purpose bandwidth reserved can not be seized by other communication standards, has therefore guaranteed the fairness of every kind of communication standard to a certain extent.Being used for of each communication standard asks to distribute or the common bandwidth B of total transmission bandwidth B is shared in the carrying request of asking to revise bandwidth according to the principle of First come first served p, therefore help to improve the utilance of transfer resource, improve the throughput of system.
Embodiment two
In embodiment one, being used for of each communication standard asks to distribute or the common bandwidth B of total transmission bandwidth B is shared in the carrying request of asking to revise bandwidth according to the principle of First come first served p, the notion of vernier has been proposed in the present embodiment.Can be by vernier with common bandwidth B pDistribute to every kind of communication standard, for example can be with common bandwidth B by a vernier pDistribute to two kinds of communication standards, can be by two verniers with common bandwidth B pDistribute to three kinds of communication standards etc.In addition, can also be by vernier with common bandwidth B pDistribute to every kind of business in every kind of communication standard.
