Abstract
The present invention relates to methods and arrangements for facilitating an efficient connection setup. The present invention specifies rules for defining the signaling of connection setup messages from user equipments such as to apply one single transmission if an assigned uplink transmission grant for transmitting the connection setup messages is sufficiently large while applying separate transmissions if the size indicated in said uplink transmission grant is not sufficient. Thus, a sufficiently large grant allows a parallel execution of the connection setup messages.
Claims20
A method in a terminal device when setting up a communication connection in a radio access network, including the steps of:
- ascertaining, in a received initial uplink transmission grant with respect to a network node, a size of the uplink transmission indicated therein;
- determining whether the size of the uplink transmission indicated by the received initial uplink transmission grant allows transmission of a plurality of connection establishment request messages to the network node;
- in response to a positive determination, transmitting said plurality of connection establishment request messages to the network node while applying one single transmission;
- and
- in response to a negative determination, transmitting said plurality of connection establishment request messages to the network node while applying separate transmissions.
A terminal device, comprising:
- first electrical circuitry to ascertain, in a received initial uplink transmission grant with respect to a network node, a size of the uplink transmission indicated therein;
- the first electrical circuitry to determine whether the size of the uplink transmission indicated by the received initial uplink transmission grant allows transmission of a plurality of connection establishment request messages to the network node;
- second electrical circuitry to, in response to a positive determination, initiate transmission of said plurality of connection establishment request messages to the network node while applying one single transmission;
- and
- the terminal device to, in response to a negative determination, transmit said plurality of connection establishment request messages to the network node while applying separate transmissions.
A method in a network node of a radio access network, said network node responsible for providing a connection setup functionality to a terminal device, the method comprising:
- autonomously determining in the network node a size of a grant for uplink transmission of said terminal device based on cell-specific or load-specific parameters;
- assigning, in response to the determining step, in a random access response said grant to the terminal device;
- and
- receiving from the terminal device one single transmission comprising one single connection establishment request message and an indication that the terminal device has further data to transmit.
A network node of a radio access network, said network node responsible for providing a connection setup functionality to a terminal device, comprising:
- first electrical circuitry to autonomously determine in the network node a size of a grant for uplink transmission of said terminal device based on cell-specific or load-specific parameters;
- second electrical circuitry to assign, in response to the autonomous determination, in a random access response said grant to the terminal device;
- and
- the network node to receive from the terminal device one single transmission comprising one single connection establishment request message and an indication that the terminal device has further data to transmit.
