Abstract: Various communication systems may benefit from mechanisms for access-based communications. For example, machine-type communication in long term evolution (LTE) communication systems may benefit from a mechanism for user equipment access-based machine-to-machine communication. A method can include a user equipment entering a transaction state. The method can also include suspending reception of paging messages during an idle period of the transaction state.

Abstract: Various communication systems may benefit from the proper use of control channel resources. For example, certain communication systems associated with the long tem evolution of the third generation partnership project may benefit from physical downlink control channel transmission improvement for paging message coverage enhancement. A method can include obtaining a coverage enhancement paging parameter at a user equipment. The method can also include calculating, by the user equipment, a paging frame or paging occasion according to the paging parameter. In another example, a method can include receiving, at a user equipment, a coverage enhancement paging radio network temporary identifier for use in coverage enhancement mode. The method can also include decoding a physical downlink control channel based on the coverage enhancement paging radio network temporary identifier.

Abstract: There are provided measures for enabling/realizing more efficient radio link problem handling in a mobile communication system. Such measures exemplarily comprise detecting a radio problem of a radio link carrying a network connection of a communication device, and initiating a recovery procedure for recovering the connection on said radio link and a re-establishment procedure for re-establishing the connection on an alternative radio link, upon detection of the radio link problem, before a radio link failure of said radio link is declared.
