The RRC connection method that the embodiment of the present application one provides can be as shown in figure 5, this method specifically includes:

S501, the network equipment send first message to user equipment, and first message is used to indicate user equipment RRC connection and builds Vertical failure.Corresponding, user equipment receives the first message that the network equipment is sent.Illustratively, first message can refuse for RRC (reject) message (the RRC connection for indicating refusal UE) absolutely.

And user equipment can send RRC connection request (RRC to the network equipment before receiving first message Connection request) message, the RRC connection request is for requesting the network equipment and the user equipment Between establish RRC connection.If the network equipment establishes RRC connection failure, then a RRC reject message is responded.

S502, user equipment is based on the first timer and/or the second timer re-establishes RRC connection, wherein if first Timer is in the activation phase and then indicates that supplement uplink does not allow using indicating to mend if the first timer is in the inactive phase Fill with line link allow using, if the second timer is in the activation phase indicate non-supplemental uplink not and allow using, if Two timers be in the inactive phase then indicate non-supplemental uplink allow using.

For example, in 5G scene user equipment can safeguard two Timer (i.e. the first timer and the second timer, wherein First timer, the second timer are only a kind of exemplary illustrations, and the first timer is referred to as SUL bar timer, the Two timers are referred to as NUL bar timer, and UE forbids accessing respective cell when physical significance is two Timer activation NUL or SUL, specifically, the first timer activate when UE forbid access respective cell SUL, the second timer activate when UE Forbid accessing the NUL of respective cell.

Illustratively, user equipment can activate first timer, N when n times continuous on SUL establish RRC connection failure For the integer greater than 0.User equipment can also activate second timer when continuous N on NUL time establishes RRC connection failure, and M is Integer greater than 0, wherein N may be the same or different with M.User equipment can also reach in the transmission power on NUL It activates second timer to exist when second threshold, at this moment can terminate the remaining re-transmission on NUL in advance.User equipment is can be Activation when establishing number of RRC connection failure the sum of greater than third threshold value is established on the number and NUL of RRC connection failure on SUL First timer and second timer.

User equipment is by two timers of maintenance in the embodiment of the present application, thus can basis after establishing RRC failure The state of two timers determines which uplink to re-establish RRC connection using.

Under normal circumstances, DL Reference Signal Received Power can first be measured when user equipment Network with Random Multiple Access System equipment (reference signal received power, RSRP), if DL RSRP is greater than or equal to first threshold, (the application is implemented First threshold is known as SUL-RSRP-Threshold in example, but the name of the threshold value is not specifically limited), then user equipment RRC is established with the network equipment using NUL to connect.If DL RSRP is less than SUL-RSRP-Threshold, user equipment can make RRC is established with the network equipment with SUL to connect.

In embodiments of the present invention, user equipment be based on the first timer and/or the second timer re-establish RRC it Before, user equipment can also measure DL RSRP.In this way, two timers of the user equipment by maintenance, are establishing RRC failure It can determine which uplink to re-establish RRC connection using according to the state of two timers afterwards, it can be there are several types of Situation:

Situation one: if first timer and second timer are in the inactive phase, and DL RSRP is less than SUL-RSRP- Threshold, user equipment re-establish RRC connection using SUL.

Situation two: if first timer and second timer are in the inactive phase, and DL RSRP is greater than or equal to SUL- RSRP-Threshold, user equipment re-establish RRC connection using NUL.

Situation three: if second timer is in the activation phase, and first timer is in the inactive phase, and user equipment can make RRC connection is re-established with NUL.It is, working as first timer un-activation, when the second timer activates, UE can ignore NR The relationship of DL RSRP and sul-RSRP-Threshold are reattempted to be accessed on SUL.

Situation four: if first timer is in the activation phase, and second timer is in inactive phase, and downlink signal quality Value is greater than or equal to first threshold, and user equipment can be used NUL and re-establish RRC connection.It is, at first timer In the activation phase, and when second timer is in the inactive phase, while DLRSRP >=sul-RSRP- that UE measurement obtains Threshold, then UE is reattempted to accesses on NUL.

Situation five: if first timer and second timer are in the activation phase, user equipment be can choose using adjacent small The uplink in area re-establishes RRC connection.

In addition, when the summation of the number of the upper RRC connection foundation failure of the number+SUL of RRC connection foundation failure on NUL is big In N, wherein N is the read-around ratio value that user equipment establishes RRC connection failure on SUL, and UE can be attempted through other cells Access.In addition, UE, when transmission power reaches maximum value on NUL, UE can terminate the remaining re-transmission on NUL in advance, and cut It shifts to SUL and re-executes RRC access.

By the above method, when user equipment can first measure DL RSRP before a random access, if DL RSRP >= SUL-RSRP-Threshold, can be suitable by NUR-SUL-adjacent cell uplink when RRC is connect establishing with the network equipment Sequence selection access.If DL RSRP < SUL-RSRP-Threshold, can be by SUL-when RRC is connect establishing with the network equipment The sequential selection of adjacent cell uplink accesses.And corresponding uplink can be skipped in the activation of certain timer, for example, working as When above-mentioned first timer activates, user equipment can skip SUL and re-establish RRC connection.In another example above-mentioned second timer When activation, user equipment can skip NUL and re-establish RRC connection.For another example working as above-mentioned first timer and second timer When activating, user equipment, which can skip NUL and re-establish RRC with SUL, to be connected, and the uplink of other cells is selected to build again Vertical RRC connection, it is specific as shown in Figure 6.
