Communication method and device

1. A method for communication, comprising:

receiving data sent by a user equipment (UE);

determining a core network which provides a communication service for the UE; and

when the core network is a next generation core network (NG-Core), performing a data format conversion on the data to obtain designated data wherein the obtained designated data has a data format that is consistent with the NG-core, and sending the designated data to the NG-core; and

when the core network is a fourth-generation evolved packet core (EPC), sending the data to the fourth-generation EPC, and

wherein the data format conversion is enabled when the core network is the NG-Core and the data format conversion is disabled when the core network is the fourth-generation EPC, and

wherein the data is user data, and performing the data format conversion on the data to obtain the designated data comprises:

performing the data format conversion on the user data at a packet data convergence protocol (PDCP) layer to obtain the designated data, wherein the obtained designated data has the data format that is consistent with a user data format of the NG-Core.

2. The method according to claim 1 , wherein the data is signaling data, and performing the data format conversion on the data to obtain the designated data comprises:

performing the data format conversion on the signaling data at a radio resource control (RRC) layer to obtain the designated data, wherein the obtained designated data has the data format that is consistent with a signaling data format of the NG-Core.

3. The method according to claim 1 , wherein the data format refers to at least one of: a number of fields, a field length, an arrangement order of fields, or a meaning of fields in the data.

4. A device for communication, comprising:

a processor; and

a memory for storing a processor-executable instruction, wherein

the processor is configured to:

receive data from a user equipment (UE); determine a core network which provides a communication service for the UE; and

when the core network is a next generation core (NG-Core), perform a data format conversion on the data to obtain designated data wherein the obtained designated data has a data format that is consistent with the NG-Core, and send the designated data to the NG-Core; and

when the core network is a fourth-generation evolved packet core (EPC), send the data to the fourth-generation EPC, and

wherein the data format conversion is enabled when the core network is the NG-Core and the data format conversion is disabled when the core network is the fourth-generation EPC, and

wherein the data is user data, and the processor configured to perform the data format conversion on the data to obtain the designated data is further configured to:

perform the data format conversion on the user data at a packet data convergence protocol (PDCP) layer to obtain the designated data, wherein the obtained designated data has the data format that is consistent with a user data format of the NG-Core.

5. The device according to claim 4 , wherein the data is signaling data, and the processor configured to perform the data format conversion on the data to obtain the designated data is further configured to:

perform the data format conversion on the signaling data at a radio resource control (RRC) layer to obtain the designated data, wherein the obtained designated data has the data format that is consistent with a signaling data format of the NG-Core.

6. The device according to claim 4 , wherein the data format refers to at least one of: a number of fields, a field length, an arrangement order of fields, or a meaning of fields in the data.
