Techniques to manage integrity protection
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.
1. 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.
2. The method of claim 1 , wherein the first network node is a radio access network (RAN) node and the second network node is a core network node.
3. The method of claim 2 , wherein the core network node includes an access and mobility management function (AMF).
4. The method of claim 1 , wherein the message is a PDU session resource notify message to release a PDU session.
5. 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).
6. The method of claim 5 , wherein the message is a PDU session resource notify message to release a PDU session.
7. 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.
8. The first network node of claim 7 , wherein the first network node is a radio access network (RAN) node and the second network node is a core network node.
9. The first network node of claim 8 , wherein the core network node includes an access and mobility management function (AMF).
10. The first network node of claim 7 , wherein the message is a PDU session resource notify message to release a PDU session.
11. 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).
12. The second network node of claim 11 , wherein the message is a PDU session resource notify message to release a PDU session.
