The embodiment of the invention provides a multi-protocol compatible processing method aiming at the situation that when an industry customized terminal and a non-industry customized terminal exist in the same network, the network cannot be compatible with and support an industry standard terminal and a 3GPP standard terminal at the same time, and the method comprises the following specific steps:
step S301, according to the capability information of the terminal equipment, identifying the communication standard type supported by the terminal equipment.

Step S302, performing information interaction with the terminal equipment by adopting a protocol version corresponding to the communication standard type supported by the terminal equipment.
Since terminal device 12 and terminal device 13 may be different types of terminals, when access network device 11 recognizes the types of terminal device 12 and terminal device 13, the communication protocol version used by terminal device 12 and the communication protocol version used by terminal device 13 may be determined. Further, access network device 11 may perform information interaction with terminal device 12 by using the protocol version corresponding to terminal device 12, and may also perform information interaction with terminal device 13 by using the protocol version corresponding to terminal device 13.
The vendor or industry extends the "OCTET STRING" of the message by means of customized cells. The network side identifies the terminal type and the supporting ability by the methods of the logic channel ID or the special cell used in the UE random access process, and then sends the code stream corresponding to different protocol versions to the terminal according to the terminal type and decodes the message received from the terminal according to different protocol versions. The cell consists of a header, in which control information is contained, and a field, in which user information or other management information, which is broken down into data blocks, is contained. Each cell consists of a header of 5 bytes and a payload of 48 bytes.
The embodiment of the invention identifies the communication standard type supported by the terminal equipment through the capability information of the terminal equipment, and different types of terminal equipment adopt different protocol versions during communication, so that the communication between the access network equipment and different types of terminal equipment can be realized by adopting the protocol version corresponding to the communication standard type supported by the terminal equipment to carry out information interaction with the terminal equipment, thereby realizing the simultaneous compatibility of the same network and the terminal supporting the industrial standard and the terminal supporting the 3GPP standard.
Fig. 4 is a signaling diagram of communication between an access network device and a terminal device according to an embodiment of the present invention. In this embodiment, the terminal device communicating with the access network device may be the terminal device 12 in the above embodiment, or may be the terminal device 13, and the communication process specifically includes the following steps:
step 401, the access network device sends system information to the terminal device.
Step 402, the terminal device performs random access.
Step 403, the terminal device sends an RRC connection request to the access network device.
And step 404, the access network equipment and the terminal equipment perform RRC connection establishment.
Step 405, the terminal device sends an RRC connection setup complete to the access network device.
Step 406, the access network device sends a UE capability query to the terminal device.
Step 407, the terminal device sends the UE capability information to the access network device.
Step 408, the access network device sends the RRC connection reconfiguration to the terminal device.
Step 409, the terminal equipment sends the RRC connection reconfiguration complete to the access network equipment.
On the basis of the above embodiment, identifying the communication standard type supported by the terminal device according to the capability information of the terminal device includes several possible implementation manners as follows:
one possible implementation is: and identifying the communication standard type supported by the terminal equipment according to the identification information of the logical channel used by the terminal equipment in the random access process.
Specifically, an index 01101 of a Logical Channel Identification (LCID) of an Uplink Shared Channel (UL-SCH) may be added to 3GPP 36.321E20, as shown in table 1.
TABLE 1
When the terminal device uses the logical channel identified by 01101 in the random access process, the terminal device sends an RRC connection request to the access network device on the logical channel identified by 01101, and when the access network device judges that the access network device receives the RRC connection request sent by the terminal device on the logical channel identified by 01101, the terminal device is an industry customized terminal.
Another possible implementation is: and identifying the communication standard type supported by the terminal equipment according to the information element carried in the Radio Resource Control (RRC) connection request sent by the terminal equipment. And the information element carried in the RRC connection request is used for identifying that the terminal equipment is an industry customized terminal or a non-industry customized terminal.
In this embodiment, the industry standard may specifically be a B-trunk protocol, the RRC connection request includes a cell, the cell is specifically an IsTrunkinguser, and if the IsTrunkinguser included in the RRC connection request sent by the terminal device to the access network device is 1, it indicates that the terminal device is a trunking terminal, that is, an industry customized terminal. If IsTrunkingUser included in an RRC connection request sent by the terminal equipment to the access network equipment is 0, the terminal equipment is represented as a non-cluster terminal, namely a non-industry customized terminal.
In addition, the step S302 of performing information interaction with the terminal device by using the protocol version corresponding to the communication standard type supported by the terminal device includes the following possible situations:
one possible scenario is: and encoding the RRC connection reconfiguration message by adopting a protocol version corresponding to the communication standard type supported by the terminal equipment, and sending the encoded RRC connection reconfiguration message to the terminal equipment.
If the terminal equipment is an industry customized terminal, the access network equipment uses RRCConnectionReconfiguration-reporting-Ies to code the RRC connection reconfiguration, secondarily codes the coded RRC connection reconfiguration and sends the secondarily coded RRC connection reconfiguration to the terminal equipment.
If the terminal equipment is a non-industry customized terminal, the access network equipment uses RRCConnectionReconfiguration-v8m0-IEs to code RRC connection reconfiguration, secondarily codes the coded RRC connection reconfiguration and sends the secondarily coded RRC connection reconfiguration to the terminal equipment.
Another possible scenario is: and decoding the received message sent by the terminal equipment by adopting a protocol version corresponding to the communication standard type supported by the terminal equipment.
If the terminal equipment is an industry customized terminal, the access network equipment uses the access network equipment to decode the received message sent by the terminal equipment by using the measurement report-sounding-Ies.
In this embodiment, the access network device identifies the communication standard type supported by the terminal device according to the identification information of the logical channel used by the terminal device in the random access process, or identifies the communication standard type supported by the terminal device according to the cell carried in the radio resource control RRC connection request sent by the terminal device, and performs information interaction with the terminal device according to the protocol version corresponding to the communication standard type supported by different terminal devices, so that the access network device can communicate with different types of terminal devices, thereby implementing the terminal compatible with the same network and supporting the industry standard and the terminal of the 3GPP standard.
