Abstract
Embodiments of the present disclosure provide a reconfiguration method and related products, where the method includes: receiving, by a user equipment, a reconfiguration instruction from a network device, wherein the reconfiguration instruction is used to instruct reconfiguration of a PDCP layer; reconfiguring the PDCP layer and transmitting an EM) by the user equipment. Embodiments of the present disclosure can prevent other bearers from being affected by a change in the PDCP layer, thereby ensuring data continuity of other services.
Claims20
A reconfiguration method, comprising:
- receiving, by a user equipment, a reconfiguration instruction from a network device, wherein the reconfiguration instruction is used to instruct reconfiguration of a packet data convergence protocol (PDCP) layer;
- and
- reconfiguring the PDCP layer and transmitting an end-marker (EM), by the user equipment;
- when the EM is defined only in a new radio (NR) PDCP protocol and reconfiguration of the PDCP layer of the user equipment is to switch from a long term evolution (LTE) PDCP to an NR PDCP, before the user equipment transmits the EM, the method further comprising:
- performing, by the user equipment, resetting processing, wherein the resetting processing comprises at least one of:
- resetting a robust header compression (ROHC), resetting a protocol data unit (PDU) sequence number (SN), and resetting a hyper frame number (HFN);
- and
- when the EM is defined only in an NR PDCP protocol and reconfiguration of the PDCP layer of the user equipment is to switch from an NR PDCP to an LTE PDCP, or when the EM is defined in both the NR PDCP protocol and an LTE PDCP protocol, after the user equipment transmits the EM, the method further comprises:
- performing, by the user equipment, resetting processing, wherein the resetting processing comprises at least one of:
- resetting a ROHC, resetting a PDU SN, and resetting a HFN.
7 more elements
A user equipment, comprising a processor, a transceiver and a memory, wherein:
- the transceiver is configured to receive a reconfiguration instruction from a network device, wherein the reconfiguration instruction is used to instruct reconfiguration of a packet data convergence protocol (PDCP) layer;
- the memory has executable instructions stored thereon that when executed by the processor cause the processor to:
- reconfigure the PDCP layer;
- and
- the transceiver is further configured to transmit an end-marker (EM);
- when the EM is defined only in a new radio (NR) PDCP protocol and reconfiguration of the PDCP layer of the user equipment is to switch from a long term evolution (LTE) PDCP to an NR PDCP, before transmitting the EM, the memory further has executable instructions stored thereon that when executed by the processor cause the processor to:
- perform resetting processing, wherein the resetting processing comprises at least one of:
- resetting a robust header compression (ROHC), resetting a protocol data unit (PDU) sequence number (SN), and resetting a hyper frame number (HFN);
- and
- when the EM is defined only in an NR PDCP protocol and reconfiguration of the PDCP layer of the user equipment is to switch from an NR PDCP to an LTE PDCP, or when the EM is defined in both the NR PDCP protocol and an LTE PDCP protocol, after transmitting the EM, the memory further has executable instructions stored thereon that when executed by the processor cause the processor to:
- perform resetting processing, wherein the resetting processing comprises at least one of:
- resetting a ROHC, resetting a PDU SN, and resetting a HFN.
