Problems solved by technology

[0003] In the existing standard protocol, it only describes how the user equipment obtains the address information of the P-CSCF in the network scenario, and there is no technology that allows the remote user equipment (that is, the user equipment without network coverage) to obtain the P-CSCF address information in the IMS network. CSCF address information, so that the remote user equipment can complete the registration process of the session initiation process (English: Session Initiation Protocol, abbreviation: SIP), so as to further obtain the MCPTT service

Abstract

Embodiments of the present invention provide a wireless communication method, remote user equipment and relay user equipment. The method includes: the remote user equipment receives at least one proxy call session control function P-CSCF address sent by the relay user equipment; the remote user equipment determines the target P-CSCF address from at least one P-CSCF address, and the target P-CSCF address It is used when the remote user equipment initiates a session registration process. The remote user equipment in the embodiment of the present invention can obtain the P-CSCF address in the IMS network through the relay user equipment, so that the remote user equipment can execute the SIP registration process according to the obtained P-CSCF address, thereby further obtaining the MCPTT service.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and more specifically, to a method for wireless communication, a remote user equipment, and a relay user equipment. Background technique [0002] The push-to-talk (English: Mission Critical Push To Talk over LTE, abbreviated: MCPTT) application based on Long Term Evolution (English: Long Term Evolution, abbreviated: LTE) includes a network operation mode (English: : network Mode operation via Relay, Chinese: NMO-R), that is, the remote user equipment (English: remote User Equipment, abbreviated: remote UE) can realize the connection with the network through the relay user equipment (English: RelayUser Equipment, abbreviated: UE_R) Communication, access to MCPTT business. In the existing research on the MCPTT standard, an architecture based on IP Multimedia Subsystem (English: IP Multimedia Subsystem, abbreviated: IMS) is proposed, that is, the user equipment obtains th...
