Embodiment approach

[0126] As an optional implementation, the method also includes:

[0127] The first UE receives a downlink message, where the downlink message includes downlink information returned by the network side for signaling and / or data of the second UE;

[0128] The first UE sends the downlink information to the second UE.

[0129] The receiving of the downlink message may be receiving the downlink message from the network side, for example: receiving the above-mentioned downlink message sent by the network element of the access network corresponding to the first UE or the second UE.

[0130] The above-mentioned downlink information may be information content returned to the second UE by the network side after receiving the above-mentioned signaling and / or data, for example: a response requested by the second UE.

[0131] In this implementation manner, the first UE may receive the downlink message of the second UE.

[0132] In the embodiment of the present invention, the first UE acq...

Embodiment 1

[0238] In this embodiment, the proxy RRC system message request message is taken as an example for illustration:

[0239] UE2 in idle state or inactive state wants to obtain some system information, but the PRACH resource that UE2 can use to send RRC SystemInfoRequest message (RRCSystemInfoRequest) is not configured in SIB1 or the uplink synchronization of UE2 fails. At this time, UE2 can use connected state UE1 to obtain Send an uplink RRC message, the process is as follows:

[0240] Step 1: UE2 generates a first RRC message container (which includes an RRC system message request message and / or UE2 identifier), and / or a proxy indication information is used to indicate that UE1 or the network side Other SI request is sent in a proxy form;

[0241] Step 2: UE2 sends the first RRC message container to UE1 through the internal interface of the multi-card terminal or the interface between terminals;

[0242] Step 3: UE1 is in the connected state. After receiving the interface mes...

Embodiment 2

[0246] In this embodiment, the proxy registration update / TAU process is taken as an example for illustration:

[0247] Assume that UE2 is in idle state and UE1 is in connected state.

[0248] Step 1: UE1 and UE2 reside in cell 1, which is the serving cell of gNB1;

[0249] Step 2: Due to the mobility of the multi-card terminal, UE1 is handed over to cell 2, UE2 is reselected to cell 3, and cells 2 and 3 are serving cells of gNB2.

[0250] Step 3: During the handover process of UE1, the current AMF will obtain the association relationship between UE1 and UE2 from the original AMF (old AMF);

[0251] Step 4: UE2 triggers a registration update (periodic registration or cell 3 does not belong to RA), and generates a first NAS message container, which includes at least one of the following:

[0252] Registration request, proxy registration update indication, UE2 5G-S-TMSI, information related to the cell where UE2 currently resides (such as the last visited TAI, selected PLMN, ID...

Abstract

The invention provides an information transmission method, a user terminal and an access network element. The method comprises the following steps that: first UE (User Equipment) acquires signaling and / or data of second UE; and the first UE sends first information, wherein the first information comprises signaling and / or data of the second UE. The embodiments of the present invention can improve the transmission capability of the UE.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, a user terminal and an access network element. Background technique [0002] Currently, some terminals can support an idle state (Idle), an inactive state (Inactive) and a connected state (Connectted). Further, some terminals can also support multiple Subscriber Identity Modules (SIMs), that is, Multi-SIMs, and these SIMs can be physical cards or virtual cards (for example: eSIM), and each SIM can be called a user terminal (User Equipment, UE) or corresponds to a UE. Although, at present, regardless of a terminal that supports multiple SIM cards or a terminal that only supports a single SIM, UE (a terminal that supports one of multiple SIM cards, or a terminal that only supports a single SIM) can only pass through the corresponding The SIM card sends information, so the transmission capability of the UE is relatively poor. Co...
