Abstract
Wireless communication methods are described for a user plane integrity protection failure detection and handling, determination and management of integrity protection enabled data rate that exceeds or is close to exceeding a user equipment's capability or threshold, and management of integrity protection or encryption mechanisms in a dual-connectivity system that includes a master network node and a secondary network node.
Claims12
A wireless communication method, comprising:
- determining, by a first network node, that a maximum integrity protection enabled data rate capability of a user equipment has been or will be exceeded;
- and
- transmitting, by the first network node to a second network node, a message indicating to the second network node that the maximum integrity protection enabled data rate capability has been or will be exceeded,
- wherein the message indicates a rejection of a request received from the second network node for a PDU session addition configured with integrity protection.
A wireless communication method, comprising:
- receiving, by a second network node from a first network node, a message indicating that a maximum integrity protection enabled data rate capability has been or will be exceeded,
- wherein the first network node is a radio access network (RAN) node and the second network node is a core network node comprising a mobility management function (AMF), and
- wherein the message indicates a rejection of a request sent by the second network node to the first network node for a PDU session addition configured with integrity protection;
- and
- transmitting, by the second network node, the message to a session management function (SMF).
A first network node, comprising a processor configured to:
- determine that a maximum integrity protection enabled data rate capability of a user equipment has been or will be exceeded;
- and
- transmit, to a second network node, a message indicating to the second network node that the maximum integrity protection enabled data rate capability has been or will be exceeded,
- wherein the message indicates a rejection of a request received from the second network node for a PDU session addition configured with integrity protection.
A second network node, comprising a processor configured to:
- receive, from a first network node, a message indicating that a maximum integrity protection enabled data rate capability has been or will be exceeded,
- wherein the first network node is a radio access network (RAN) node and the second network node is a core network comprising a mobility management function (AMF),
- wherein the message indicates a rejection of a request sent by the second network node to the first network node for a PDU session addition configured with integrity protection;
- and
- transmit the message to a session management function (SMF).
