To implement an algorithm that dynamically tries another algorithm on failure (e.g. A after B), the first (failing) algorithm should not change or damage anything. This commit refactors algorithm A and B to delay the actual allocation until it is known that the allocation will not fail.

If this was for an DL TBF, the first common TS was selected, otherwise the least used common TS was selected for an UL TBF. The shrinking of the UL set (to 1<<first_common_ts) is done in the latter case. This commit removes an additional code path that aligns the UL set to first_common_ts, because it has no more influence on the set of common TS after both UL and DL TBF have been allocated.

This scenario is not covered by the existing tests. This commit adds a test, that allocates as man as possible TBFs several times with different test modes without clearing the BTS (and thus the TBF list) in between. The number of allocated DL TBFs in each round is expected to be constant.

This make it difficult to interleave the TBF allocation like it happens with real MS. This commit refactors the allocation loop into alloc_many_tbfs and adds support for TLLIs, which are derived from the counter value and used to retrieve an old MS object if alloc_many_tbfs is called a second time. Note that this does not make a difference for the existing tests.

This patch adds a is_idle() method that will return true if the MS object is just kept by the guard from being idle. In that case, the MS object would either be deleted or return true for GprsMs::is_idle() after the guard's destruction, provided that no TBF attachment took place in between.

TBFs can be searched globally by TFI and TRX number. This conflicts with the use of the same TFI for different TBF on different PDCH. This use case requires the specification of the PDCH as additional search dimension. This commit moves the TFI index TBF arrays into the PDCH objects. The related methods are updated accordingly.

This commit modifies algorithm_a() to allow the sharing of TFI between different PDCH. Since algorithm A only assigns a single slot to each TBF, the TFI of each PDCH can be assigned independently. This increases the maximum to 32 TBF per direction and per PDCH concerning the TFI allocation.

This does fit to TFI reuse for different slots, since this were tightly coupled with the slot selection. This commit just moves the TFI selection into the alloc_algorithm functions. The tfi parameter is removed from the the TFI alloc functions. The trx parameter is changed into use_trx to optionally limit the trx selection (same semantics like in tfi_find_free).

It iterates through all TBFs, records on which PDCH it uses which TFI and check for conflicts. It also checks the bits returned by pdch->assigned_tfi(). The latter suffers from an bug in that method (no separation of uplink and downlink), so a conditional fprintf is used instead of an assertion. The method tfi_find_free is checked for conflicts after allocations.

The outer loop exit condition was not updated accordingly. This bug would would only lead to an error if there were multiple TRX where the first TRX has not got any PDCH assigned. This commit corrects the break condition.

Nevertheless UL-only slots will never be used, since only one uplink slot (which must be a common slot) will be used. This patch changes the code to only include common slots in the capacity sum. Note that this might not be optimal if algorithm B supported multiple uplink slots.

This statistically prefers the first time slots, especially with short living TBFs. So when the first TBF is triggered by an uplink transfer (which generally results in a short-lived TBF) the potentially longer living DL TBF will be bound to the same slot. When another MS then requests an uplink TBF, it will get the same slot (no UL TBF currently active). This commit changes the algorithm to base its selection on reserved slots instead.

This commit updates find_possible_pdchs() to only consider slots with the same TSC if more that 1 slot shall be assigned. Note that the first PDCH's TSC will be used as reference, so if two or more groups with a common TSC are configured, only the first will be used. This restriction does not apply to algorithm A, since it will not assign more than one slot and therefore sets the max_slots parameter to 1.

They correspond to the potential use of the PDCHs and can be used to achieve a more uniform slot allocation. This commit adds bit set based methods to GprsMs and gprs_rlcmac_trx and a counter to gprs_rlcmac_pdch. The current TRX will also be stored in the MS object.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (520c2919f4bf5d0d0d6dd254e8d76a6876b3b481) \ N -- N -- N (50076d7a18e03fee84017df4066efa1429904c41) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B.

Basically algorithm B will be selected if the PDCH usage is low to improve throughput and latency. Algorithm A will be selected to support more concurrent MS. This commit adds a first simple state-less version of this algorithm that always tries B first and only if that fails A is tried afterwards.

To implement an algorithm that dynamically tries another algorithm on failure (e.g. A after B), the first (failing) algorithm should not change or damage anything. This commit refactors algorithm A and B to delay the actual allocation until it is known that the allocation will not fail.

If this was for an DL TBF, the first common TS was selected, otherwise the least used common TS was selected for an UL TBF. The shrinking of the UL set (to 1<<first_common_ts) is done in the latter case. This commit removes an additional code path that aligns the UL set to first_common_ts, because it has no more influence on the set of common TS after both UL and DL TBF have been allocated.

This scenario is not covered by the existing tests. This commit adds a test, that allocates as man as possible TBFs several times with different test modes without clearing the BTS (and thus the TBF list) in between. The number of allocated DL TBFs in each round is expected to be constant.

This patch adds a is_idle() method that will return true if the MS object is just kept by the guard from being idle.

This does fit to TFI reuse for different slots, since this were tightly coupled with the slot selection. This commit just moves the TFI selection into the alloc_algorithm functions. The tfi parameter is removed from the the TFI alloc functions. The trx parameter is changed into use_trx to optionally limit the trx selection (same semantics like in tfi_find_free).

It iterates through all TBFs, records on which PDCH it uses which TFI and check for conflicts. It also checks the bits returned by pdch->assigned_tfi(). The latter suffers from an bug in that method (no separation of uplink and downlink), so a conditional fprintf is used instead of an assertion. The method tfi_find_free is checked for conflicts after allocations.

In case a TMSI is re-used too early and we do page using TMSI we can't know which of the two MS is responding to us. We could change the "secure channel" routine to ask for the IMSI and only then stop the paging. As we don't have ciphering there is not much use in using the TMSI. Add a mode "no assign-tmsi" that will not assign the TMSI during LU. Now CM Service Request and Paging Response will work using the IMSI.
