patch: 8_paging
by Andreas.Eversberg 23 May '09

23 May '09

Paging refers to a BTS. To page a mobile phone, the current location is required. If paging succeeds or expires, the BTS structure is also given to the callback function (cbfn). Because paging refers to a BTS, the cbfn (callback function) must include a pointer to bts. There is no implementation yet for the paging of the actual BTS where the subscriber is located. gsm_04_08.c always uses BTS 0 (in later patches) The database requires improvement to store the current BTS number.

patch: 4_txdelay
by Andreas.Eversberg 23 May '09

23 May '09

To slow down transmission of many ABIS frames at a time, a delay timer is used for the E1's time slot. This timer replaces the "usleep()" function, so the process will not block the execution of libbsc. The timer is started after a frame is transmitted. If another frame is in the transmit queue, the frame will only be queued until the timer times out. If the timer is not running or times out, the frame is transmitted and the timer is restarted. The problem with partly provisioned TRX (locks show on LMT) is solved. The adjustment for the inter frame delay of 50 miliseconds is for further study.

patch: 7_polling
by Andreas.Eversberg 23 May '09

23 May '09

An application that has own events and file descriptors, must poll select function ob libbsc. A "polling" flag is used to enable polling. In this case select() will not sleep until file descriptor events occurr or nearest timer expires. Also a return value will indicate if there was an event that has been handled. If there was an event, the application decides to poll again and don't wait. In case for bsc_hack, the polling flag is not set. select will sleep as usual.

patch: 1_timer
by Andreas.Eversberg 23 May '09

23 May '09

this patch renames the timer functions to avoid name collisions with libmisdn. the return value of bsc_update_timers() is required for applications to find out if a timer was fired. (this is required for later patches).

patch: 3_llist
by Andreas.Eversberg 23 May '09

23 May '09

This patch chnages the variable "new" to "_new" in order to include it in C++ code. The define "container_of" will cast pointer before assigning. Compiler with stricter options require this.

patch: 13_install
by Andreas.Eversberg 22 May '09

22 May '09

This patch moves telnet interface from bsc_hack to libbsc, so it can be used by applications also. If this makes sense, must be decided by you. This patch also includes the quick and dirty installation hook. This must be changed also.

Problem : RS232 link

Hi, I am now trying to configure the bs11 using bs11_config and I had a problem connecting via serial port. I tried then to use an USB adaptator as you did but I don't have any ttyUSB in my /dev/ I only have /dev/usbdev*.*_ep** (2 per USB port and 6 new ones appeared after connecting the USB adaptator). lsusb give me the following result: # lsusb Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 413c:3012 Dell Computer Corp.

Does anyone know why I can't see any ttyUSB? Best regards, Eric Cathelinaud
