Embodiment 1

[0166] Embodiment 1: The MN requests the SN to establish and / or modify a bearer, and the SN cannot undertake the MN's bearer allocation request, based on a single bearer.

[0167] The specific flow of message transmission between MN and SN includes:

[0168] Step 1: The MN allocates the SCG bearer and / or split bearer to the SN, and requests the SN to establish or modify the bearer.

[0169] Step 2: The SN receives the message containing the MN's request to establish or modify the bearer, and judges that it cannot fully undertake the MN's bearer establishment request according to the bearer requirements and its own available resources.

[0170] Step 3: The SN calculates the currently bearable bearer size and the bearable proportion for the current bearer according to the availability of its own resources, and initiates a bearer configuration negotiation request message.

[0171] The bearer configuration negotiation request message may modify only one bearer or modify multiple ...

Embodiment 2

[0174] Embodiment 2: The MN requests the SN to establish and / or modify the bearer, the SN cannot undertake the bearer allocation request of the MN, and the negotiation configuration message is directed to all bearers.

[0175] The specific flow of message transmission between MN and SN includes:

[0176] Step 1: The MN allocates the SCG bearer and / or split bearer to the SN, and requests the SN to establish or modify the bearer.

[0177] Step 2: The SN receives the message containing the MN's request to establish or modify the bearer, and determines that it cannot fully undertake the MN's bearer establishment request according to the bearer requirements and its own available resources.

[0178] Step 3: The SN calculates the currently bearable bearer size and the bearable proportion for the current bearer according to the availability of its own resources, and initiates a bearer configuration negotiation request message.

Embodiment 3

[0183] Embodiment 3: The MN requests to establish or modify the split bearer, and the SN proposes to undertake more proportions.

[0184] The specific flow of message transmission between MN and SN includes:

[0185] Step 1: The MN allocates a split bearer to the SN, and requests the SN to establish or modify the bearer.

[0186] Step 2: The SN receives a message containing a request from the MN to establish a bearer, and determines, according to the bearer requirement and its own available resources, that the SN can share more bearer proportions.

[0187] Step 3: The SN calculates the currently bearable bearer size and the bearable proportion for the current bearer according to the availability of its own resources, and initiates a bearer configuration negotiation request message.

[0188] The bearer configuration negotiation request message can modify only one bearer or modify multiple bearers, and the bearer configuration negotiation request message includes the bearer ID ...

Abstract

The present application discloses and provides a message transmission method and device, and a computer storage medium, so as to realize the bearer configuration negotiation between the MN and the SN, thereby improving the flexibility of bearer processing and the resource utilization of the SN and the MN. A message sending method provided by the present application includes: a secondary node SN determines that bearer configuration negotiation needs to be performed with a master node MN; the SN sends a bearer configuration negotiation request message to the MN.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a message transmission method and device, and a computer storage medium. Background technique [0002] In the EN-DC dual connectivity (E-UTRA-NR Dual Connectivity) scenario, each radio bearer is determined by the master node (Master Node, MN) of its Packet Data Convergence Protocol (PDCP) entity location and radio The cell group to which the resource is allocated, that is, the MN determines the bearer type. The MN determines the uplink / downlink aggregate maximum bit rate (Aggregate Maximum Bit Rate, AMBR) limit of the user equipment (User Equipment, UE) of the MN and the secondary node (Secondary Node, SN). The establishment of the relevant bearer on the secondary cell group (Secondary Cell Group, SCG) side can be achieved through the SN addition process or the SN modification process initiated by the MN. Taking the SN addition process as an example, the ...
