Detailed ways

The present disclosure will be further described in detail below in conjunction with the drawings and specific embodiments.

Embodiment 1

An embodiment of the present disclosure provides a paging message sending method, where the method includes:

Specifically, this embodiment may be as shown in FIG. 1 and includes:

Step 101: Determine whether a paging message to be sent by the user equipment UE is a paging message of a first type, where the paging message of the first type is: a paging message sent to the UE for the first time, Or a paging message for the first priority of the UE;

Step 102: Determine that the paging message to be sent by the UE is a paging message of the first type, and send a paging message carrying the random access configuration information to the UE.

The present embodiment can be applied to a network device that can directly send a paging message to the UE. For example, it can be a base station, and specifically, it can be an eNB, a gNB, or the like, which is not exhaustive in this embodiment.

First, a method for determining whether a paging message to be sent is a first type of paging message is described:

scene one,

It is judged by the base station itself, that is, whether it is for the idle state UE or the UE for the inactive state, the base station may be based on the cell in which the UE initiated the RRC connection establishment last time, or based on the data to be sent or the service itself. In the case of determining whether the paging message is a first type of paging message.

When the UE is an inactive UE, it may be determined whether the priority of the downlink data is the first priority based on the downlink data to be sent to the UE; if yes, determining that the paging message to be sent for the user equipment UE is The first type of paging message.

The paging message of the first priority may be the service or data for the first priority, that is, when determining that the data or service to be sent is the service or data of the first priority, determining the paging message to be sent. Is the first type of paging message.

Scene 2,

The indication information sent by the core network determines whether the paging message to be sent by the UE is a paging message of the first type.

specific:

And receiving the indication information sent by the core network; and determining, according to the indication information, whether the paging message to be sent by the user equipment UE is a paging message of the first type.

And determining, according to the indication information, whether the paging message to be sent by the user equipment UE is the first type of paging message, including:

When the indication bit included in the indication information is the first preset value, determining that the paging message to be sent by the UE is the first type of paging message;

or,

When the indication bit included in the indication information is the second preset value, it is determined that the paging message to be sent for the UE is not the first type of paging message.

The first preset value and the second preset value are different, the first preset value may be 1, and the second preset value may be 0; of course, the two may be reversed as long as the UE and the network side are the same. The analytical principle can be.

For idle state (idle state) UE:

When the downlink data arrives and the network side needs to page the UE in the idle state, the mobility management network element on the core network side, such as the MME (Mobility Management Entity) in the LTE or the AMF in the 5G (Access and Mobility) The Management Function access and mobility management function first searches for the cell in which the UE initiated the RRC connection establishment last time, and sends a paging message to the base station where the cell is located. In order to inform the base station that the paging message is the first paging for the UE or the special paging of the high priority (the paging message of the first priority), the indication information may be carried in the paging message.

Specifically, the indication information may be 1 bit. When the bit position is 1, the paging message sent by the MME/AMF is a first page or a high priority special page. When set to 0, the paging message is a common search. call.

After receiving the paging message sent by the MME/AMF, the base station checks the indication information:

If the indication information indicates that the received paging message is the first paging or the high priority special paging, the base station carries the beam information used by the UE to initiate random access in the cell in the paging message sent to the UE ( Information such as implicit or displayed beam ID), preamble code, and PRAH time-frequency resources.

If the indication information indicates that the received paging message is not a special paging, the base station sends a normal paging message to the UE.

For a light connection or inactive state (UE):

When the downlink data arrives, if the network side determines that the service or the data is special data with a high priority, the mobility management network element on the core network side, such as an MME (Mobility Management Entity) in LTE or The AMF (Access and Mobility Management Function access and mobility management function) in the 5G sends an indication message to the base station where the UE is located, and indicates that the service or data is a special service or data.

Specifically, the indication information may be 1 bit. When the bit position is 1, the service or data is characterized as a special service or data, and when set to 0, the service or data is a normal service or data.

Correspondingly, after receiving the indication information sent by the MME/AMF, the base station:

If the indication information indicates that the service or the data is a special service or data, the base station carries, in the paging message sent to the UE, beam information (such as an implicit or displayed beam ID) used by the UE to initiate random access in the cell. And/or preamble sequence code preamble code, and/or PRAH time-frequency resource information.

If the indication information indicates that the service or data is normal traffic or data, the base station sends a normal paging message to the UE.

It can be seen that by adopting the above scheme, it is possible to add random access configuration information only in the paging message of the first type; thus, it is possible to carry the random access configuration information only in the partial paging message for the UE, thereby not causing The overhead of paging messages is too large, and it can also ensure that the UE accesses the connected state quickly.
