Abstract
An apparatus, comprising at least one processor, and memory storing instructions that, when executed by the at least one processor, cause a terminal device, which is configured to support multi-radio dual connectivity with at least two different connections at least to: transmit to a network device a coordinated leave information indicating that at least one of the two different connections should be released.
Claims20
An apparatus provided in a terminal device, and comprising at least one processor, and memory storing instructions that, when executed by the at least one processor, cause the terminal device, which is configured to support multi-radio dual connectivity with at least two different connections at least to:
- determine a temporary capability restriction associated with multiple subscriber identity modules, wherein the terminal device has multiple subscriber identity modules comprising a first universal subscriber identity module (USIM) and a second USIM;
- and
- transmit, to a network device, information indicating that at least one of the two different connections should be released.
The apparatus according toclaim 2, wherein the determination to temporarily free the at least one transceiver resource is determined based on a determination to establish a radio resource control connection on the first USIM.
The apparatus according toclaim 1, wherein the instructions, when executed by the at least one processor, further cause the terminal device to cause the first USIM to perform at least one of:
- transmitting a resource release request to the second USIM before transmitting the information;
- and
- receiving a resource release confirmation from the second USIM after transmitting the information.
The apparatus according toclaim 1, wherein the information is transmitted to a master node of the network device using a radio resource control message.
The apparatus according toclaim 1, wherein the instructions, when executed by the at least one processor, further cause the terminal device to use, for transmitting the information, at least one of:
- a radio resource control message, a secondary cell group failure information message.
The apparatus according toclaim 1, wherein the instructions, when executed by the at least one processor, further cause the terminal device to receive a first configuration information characterizing a reconfiguration of a bearer associated with the terminal device after transmitting the information.
The apparatus according toclaim 7, wherein the instructions, when executed by the at least one processor, further cause the terminal device to receive, after receiving the first configuration information, a second configuration information instructing the terminal device to suspend at least one bearer associated with a master cell group, and to suspend the at least one bearer associated with the master cell group based on the second configuration information.
A method of operating a terminal device, which is configured to support multi-radio dual connectivity with at least two different universal subscriber identity module (USIM) connections, the method comprising:
- determining a temporary capability restriction;
- and
- transmitting, to a network device, information indicating that at least one of the two different USIM connections should be released.
An apparatus provided in a network device, the apparatus comprising:
- at least one processor, and memory storing instructions that, when executed by the at least one processor, cause the network device at least to:
- receive information indicating that at least one of two different connections of a terminal device, which is configured to support multi-radio dual connectivity with the least two different connections, should be released;
- and
- determine, after receiving the information, whether bearers associated with a secondary cell group can be remapped to a master cell group.
