Abstract
A multi-group call setup method and device are disclosed. The method includes determining, by a first MCPTT server, to set up a multi-group call involving N MCPTT groups, where N is an integer greater than or equal to 2, and sending, by the first MCPTT server, a call message to first UE, where the call message is used to add the first UE to the multi-group call, where a first MCPTT user is an associated user of the first UE, and where the first MCPTT user is an MCPTT user in the N MCPTT groups.
Claims20
A multi-group call setup method, comprising:
- receiving, from a second user equipment (UE), by a first mission critical push to talk (MCPTT) server of a temporary group comprising N MCPTT groups, a multi-group call setup message for setting up a multi-group call involving the N MCPTT groups, wherein the second UE is associated with a second MCPTT user which is an MCPTT user in a group of the N MCPTT groups, wherein N is an integer greater than or equal to 2;
- and
- sending, by the first MCPTT server, a first paging message to a second MCPTT server of an MCPTT group to which a first MCPTT user belongs, wherein the first MCPTT user is an associated user of a first UE, wherein the MCPTT group to which the first MCPTT user belongs is a group in the N groups, and wherein the first paging message causes the second MCPTT server to send a second paging message to the first UE paging the first UE to join the multi-group call.
A mission critical push to talk (MCPTT) system, comprising:
- a first MCPTT server of a temporary group comprising N MCPTT groups;
- and
- a second MCPTT server of an MCPTT group to which a first MCPTT user belongs, wherein the MCPTT group to which the first MCPTT user belongs is a group in the N MCPTT groups, wherein N is an integer greater than or equal to 2;
- wherein the first MCPTT server is configured to:
- receive, from a second user equipment (UE), a multi-group call setup message for setting up a multi-group call involving the N MCPTT groups, wherein the second UE is associated with a second MCPTT user which is an MCPTT user in a group of the N MCPTT groups;
- and
- send a first paging message to the second MCPTT server, wherein the first paging message causes the second MCPTT server to send a second paging message to a first UE paging the first UE to join the multi-group call, wherein the first UE is associated with the first MCPTT user.
. The MCPTT system according to claim 10, wherein the second MCPTT server is configured to send the second paging message to the first UE according to the first paging message.
A multi-group call setup method, comprising:
- receiving, from a second user equipment (UE), by a first mission critical push to talk (MCPTT) server of a temporary group comprising N MCPTT groups, a multi-group call setup message for setting up a multi-group call involving the N MCPTT groups, wherein the second UE is associated with a second MCPTT user which is an MCPTT user in a group of the N MCPTT groups, and wherein N is an integer greater than or equal to 2;
- and
- sending, by the first MCPTT server, a first notification message to a second MCPTT server of an MCPTT group to which a first MCPTT user belongs, wherein the first notification message causes the second MCPTT server to send a second notification message to a first UE instructing the first UE to join the multi-group call, wherein the first MCPTT user is associated with the first UE, and wherein the MCPTT group to which the first MCPTT user belongs is a group in the N MCPTT groups.
