Abstract

The present invention discloses a method for messages transmission in a simplified way, UE transmitting the messages to the network through the lower layer, the method includes following steps: if the lower layer indicates the message has been transmitted successfully, then starting timer, otherwise, ending the current procedure; if the UE has received response from the network before the timer expires, stopping the timer; otherwise, ending the current procedure. The method can effectively avoid unnecessary operations, and reduce energy consumption of the UE.

Claims

1. A method for use in a connection establishment procedure, comprising:

transmitting a request message from a User Equipment (UE) to a network entity through a Medium Access Control (MAC) layer;

setting an initial value of a counter, and setting a threshold value of the counter; and

indicating, by the MAC layer, whether the request message has been transmitted successfully,

if the MAC layer indicates that the request message has not been transmitted successfully, ending the connection establishment procedure with failure and without starting a timer in the UE;

or

if the MAC layer indicates that the request message has been transmitted successfully, starting the timer in the UE; and

if a response from the network entity is received before the timer expires, stopping the timer, or

if no response from the network entity is received before the timer expires,

retransmitting the request message to the network entity, changing the current value of the counter and returning to the process of the MAC layer indicating whether the request message has been transmitted successfully, if the current value of the counter is not greater than the threshold value of the counter;

or

ending the connection establishment procedure with failure, if the current value of the counter is greater than the threshold value of the counter.

2. The method according to claim 1, wherein the initial value of the counter is set to 1;

and the threshold value of the counter is set to 0.

3. The method according to claim 1, wherein the threshold value of the counter is set by the network entity and sent to the UE through a standardized message.

4. The method according to claim 1, wherein, if the threshold value of the counter is the maximum of the current counter, then changing the current value of the counter comprises increasing the current value of the counter by a number of degrees.

5. The method according to claim 1, wherein if the threshold value of the counter is the minimum of the current counter, then changing the current value of the counter comprises decreasing the current value of the counter by a number of degrees.

6. The method according to claim 1, further comprising:

setting the initial value of the counter to 1 before the MAC layer indicates whether the message has been transmitted successfully;

setting the threshold value of the counter to 0 before the MAC layer indicates whether the message has been transmitted successfully or while starting the timer; and

checking and confirming that the current value of the counter is greater than the threshold value of the counter before ending the connection establishment procedure if no response from the network entity is received before the timer expires.

7. The method according to claim 1, wherein the method further comprises:

the UE turning into an idle mode and implementing all operations from a connection mode to the idle mode before ending the connection establishment procedure.

8. The method according to claim 1, wherein:

the request message is a Radio Resource Control (RRC) request message or a counting response message.

9. The method according to claim 8, wherein the RRC request message comprises a RRC connection request message or a cell update message.

10. The method according to claim 8, wherein the method further comprises:

the UE turning into the idle mode and implementing all operations from the connection mode to the idle mode before ending the connection establishment procedure.

11. A method for use in a Radio Resource Control (RRC) connection establishment procedure, comprising:

transmitting a request message from a User Equipment (UE) to a network entity through a Medium Access Control (MAC) layer;

setting an initial value of a counter, and setting a threshold value of the counter;

indicating, by the MAC layer, whether the request message has been transmitted successfully,

if the MAC layer indicates that the request message has not been transmitted successfully, ending the RRC connection establishment procedure and without starting a timer in the UE;

or

if the MAC layer indicates that the request message has been transmitted successfully, starting the timer in the UE; and

if the UE has received a response from the network entity before the timer expires, stopping the timer, or

if the UE has not received a response from the network entity before the timer expires,

retransmitting the request message to the network entity, changing the current value of the counter and returning to the process of the MAC layer indicating whether the request message has been transmitted successfully, if the current value of the counter is not greater than the threshold value of the counter;

or

ending the RRC connection establishment procedure, if the current value of the counter is greater than the threshold value of the counter.

12. The method according to claim 11, wherein the request message comprises a Radio Resource Control (RRC) message or a counting response message.

13. The method according to claim 11, wherein setting the threshold value of the counter comprises:

14. The method according to claim 11, wherein, if the threshold value of the counter is the maximum of the current counter, then changing the current value of the counter comprises increasing the current value of the counter;

or, if the threshold value of the counter is the minimum of the current counter, then changing the current value of the counter comprises decreasing the current value of the counter.

15. The method according to claim 11, further comprising:

16. The method according to claim 11, wherein the method further comprises:

the UE turning into an idle mode and implementing all operations from a connection mode to the idle mode before ending the RRC connection establishment procedure.
