Member Function Documentation

void UmtsMacModule::recv ( Packet * p ) [virtual]

Abstract method which has to be filled with the ad-hoc operations that the module has to do to the packet received

Parameters:

pointer to the packet will be received

See also:: SAP, ChSAP

Implements Module.

Definition at line 112 of file mac-module.cc.

Here is the call graph for this function:

int UmtsMacModule::command	(	int	argc,
		const char const	argv
	)			`[virtual]`

TCL command interpreter. It implements the following OTcl methods:

addupsap <SAP instance>: add a new SAP instance to the upLayerSAP_ pointers array
adddownsap <SAP instance>: add a new SAP instance to the downLayerSAP_ pointers array

Moreover it inherits all the OTcl method of PlugIn

Parameters:

	argc	number of arguments in argv
	argv	array of strings which are the comand parameters (Note that argv[0] is the name of the object)

Returns:: TCL_OK or TCL_ERROR whether the command has been dispatched succesfully or no

See also:: PlugIn

Reimplemented from Module.

Here is the call graph for this function:

void UmtsMacModule::schedule ( Packet * p ) [virtual]

This MAC implementation supposes the RLC layer sends no more than the amount of data which the MAC layer can transmit

Member Data Documentation

int UmtsMacModule::dst_rlc_id_ [protected]

id of the RLC connected above this MAC (if this MAC is at a BS, the upper RLC entity might be in the RNC and connected to this MAC by means of the Iub interface)

Definition at line 77 of file mac-module.h.

Referenced by recv(), transmit(), and UmtsMacModule().

int UmtsMacModule::me_code_id_ [protected]

the id of the other RLC instance connected to the RLC above this MAC

Definition at line 79 of file mac-module.h.

Referenced by transmit(), and UmtsMacModule().

double UmtsMacModule::slot_duration_ [protected]

corresponding to dst_rlc_id. Note that it is used only in the core network to determine which is the destination. It is not de facto used at Mobile Equipments since all base station attempt to receive all incoming transmissions anyway.

Definition at line 87 of file mac-module.h.

Referenced by command(), transmit(), and UmtsMacModule().

std::queue<Packet*> UmtsMacModule::Q [protected]

interleaving duration. In practice, delay between MAC and PHY

Definition at line 94 of file mac-module.h.

Referenced by schedule(), and transmit().

double UmtsMacModule::initslotoffset_ [protected]

Almost unused, it is only required by the interface... maybe using a NULL pointer instead?
