Abstract

A Radio Access Network (RAN) node (e.g., BSS) and method are described herein that introduce one or more bits in any of the current system information (SI) messages or in a new SI message to ensure that a wireless device upon receipt of the SI message knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection such that the wireless device can transmit uplink Radio Link Control (RLC)/Media Access Control (MAC) radio blocks that will match the capability of the RAN node (e.g., BSS). In addition, the present disclosure relates to the wireless device and method for receiving a SI message from the RAN node (e.g., BSS) that indicates if a cell supports the Mobile Station Assisted Dedicated Core Network Selection such that the wireless device can transmit uplink RLC/MAC radio blocks that will match the capability of the RAN node (e.g., BSS).

Claims

1. A Radio Access Network (RAN) node configured to interact with a wireless device, the RAN node comprising:

a transceiver circuit;

a processor; and

,

a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions to control the transceiver circuit to;

transmit, to the wireless device, a system information (SI) message that includes one or more bits to ensure that the wireless device knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection, wherein the SI message is a SI 13 message that includes a SI 13 Rest Octets information element which includes a one bit MS_ASSISTED_DCN field which ensures that the wireless device knows if the cell supports the Mobile Station Assisted Dedicated Core Network Selection.

2. The RAN node of claim 1, wherein the processor further interfaces with the memory to execute the processor-executable instructions to control the transceiver circuit to:

in response to the transmission of the SI message, receive from the wireless device one or more Radio Link Control (RLC)/Media Access Control (MAC) radio blocks that match a capability of the RAN node.

3. A Radio Access Network (RAN) node configured to interact with a wireless device, the RAN node comprising:

a transceiver circuit;

a processor; and

,

a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions to control the transceiver circuit to;

transmit, to the wireless device, a system information (SI) message that includes one or more bits to ensure that the wireless device knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection, wherein the SI message is an Extended Coverage (EC) SI Type 2 message that includes a one bit MS_ASSISTED_DCN field which ensures that the wireless device knows if the cell supports the Mobile Station Assisted Dedicated Core Network Selection.

4. A method in a Radio Access Network (RAN) node configured to interact with a wireless device, the method comprising:

transmitting, to the wireless device, a system information (SI) message that includes one or more bits to ensure that the wireless device knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection, wherein the SI message is a SI 13 message that includes a SI 13 Rest Octets information element which includes a one bit MS_ASSISTED_DCN field which ensures that the wireless device knows if the cell supports the Mobile Station Assisted Dedicated Core Network Selection.

5. The method of claim 4, further comprising:

in response to the transmission of the SI message, receiving from the wireless device one or more Radio Link Control (RLC)/Media Access Control (MAC) radio blocks that match a capability of the RAN node.

6. A method in a Radio Access Network (RAN) node configured to interact with a wireless device, the method comprising:

transmitting, to the wireless device, a system information (SI) message that includes one or more bits to ensure that the wireless device knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection, wherein the SI message is an Extended Coverage (EC) SI Type 2 message that includes a one bit MS_ASSISTED_DCN field which ensures that the wireless device knows if the cell supports the Mobile Station Assisted Dedicated Core Network Selection.

7. A wireless device configured to communicate with a Radio Access Network (RAN) node, the wireless device comprising:

receive, from the RAN node, a system information (SI) message that includes one or more bits to ensure that the wireless device knows if a cell supports a Mobile Station Assisted Dedicated Core Network Selection, wherein the SI message is a SI 13 message that includes a SI 13 Rest Octets information element which includes a one bit MS_ASSISTED_DCN field which ensures that the wireless device knows if the cell supports the Mobile Station Assisted Dedicated Core Network Selection.

8. The wireless device of claim 7, wherein the processor further interfaces with the memory to execute the processor-executable instructions to control the transceiver circuit to:

in response to receipt of the SI message, transmit to the RAN node one or more Radio Link Control (RLC)/Media Access Control (MAC) radio blocks that match a capability of the RAN node.

9. A wireless device configured to communicate with a Radio Access Network (RAN) node, the wireless device comprising:

a transceiver circuit;

a processor; and

,

a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions to control the transceiver circuit to;
