S202, the first mobile station receives the uplink first traffic channel state information sent by the core network device.
s203, the first mobile station sends a right-grabbing request to the core network equipment on an idle channel in the uplink channel.
in this embodiment, the idle channels include a traffic channel and a non-traffic channel, and specifically, an implementable manner in which the first mobile station sends the right preemption request to the base station on the idle channel in the uplink channel is as follows: the idle channel is a non-traffic channel, specifically, the idle channel is a next channel adjacent to the CACH channel, and the uplink reverse signaling is sent on the next channel according to a first channel number of the next channel determined by the first mobile station.
in this embodiment, the uplink reverse signaling is formed by combining a 48-bit reverse channel synchronization word and a 48-bit embedded signaling, and the reverse channel burst is 96 bits. The information units which are indispensable for the signaling are an FLCO information unit and an SADDR information unit, wherein the value of the FLCO information unit is 0001012, the FLCO information unit is used for indicating that the voice group call is subjected to the right preemption operation, and the SADDR information unit is used for indicating the address of the first mobile station.

Specifically, the bit number occupied by each information unit, and the value and parameter description of each information unit are also exemplified in table one.
Optionally, when the idle channel is a non-traffic channel, specifically, the idle channel is a next channel adjacent to the CACH channel, and the uplink signaling P _ RAND signaling is sent on the next channel according to a first channel number of the next channel determined by the first mobile station; the uplink signaling P _ RAND may include an identifier for performing preemption operation on the voice group call and an identifier of an address of the first mobile station, and specifically, the structure of the uplink signaling P _ RAND may be as shown in the above structure in table one, where SK is 10112 or SK is 11002, SK represents preemption operation on the voice group call, and TADDR represents an address of each mobile station participating in the voice group call, where TADDR includes the address of the first mobile station.
another implementable way for the first mobile station to send the preemption request to the base station on the idle channel in the uplink channel is as follows: the idle channel is a traffic channel, specifically, the idle channel is a second traffic channel adjacent to the first traffic channel, and the uplink command P _ MAINT is sent on the second traffic channel according to a second channel number of the second traffic channel determined by the first mobile station.

And the idle channel is an uplink control channel, and the first mobile station transmits an uplink instruction C _ MAINT PDU in the uplink control channel according to the third channel number of the uplink control channel.
6. The method of claim 1, wherein the preemption request includes an access priority or a call type for the first mobile station;
The call types include a general call type and an emergency call type.
7. A mobile station, wherein the mobile station is a first mobile station, the mobile station comprising:
A channel state information receiving module, configured to receive uplink first service channel state information sent by a core network device, where the first service channel state information is used to instruct a second mobile station to perform voice group call on a first service channel;
an preemption request sending module, configured to send an preemption request to the core network device on an idle channel in an uplink channel, where the preemption request is used to instruct the core network device to determine whether the first mobile station meets a preset preemption condition;
And the voice group calling module is used for carrying out voice group calling on the first service channel according to the response message of successful right preemption sent by the core network equipment.
8. The mobile station of claim 7, further comprising:
