S303: when arbitrary user terminal triggered communication, judge whether the main intermediate station of the user terminal of described triggered communication exists idle logic channel, when the main intermediate station of described user terminal exists idle logic channel, the logic channel of described free time is used to communicate.
In the present embodiment, when any one user terminal triggered communication, first described user terminal judges whether the main intermediate station of described user terminal exists idle logic channel, when main intermediate station existing idle logic channel, the logic channel of the free time of described main intermediate station is used to communicate.
In practical application, the CACH information of the radiofrequency signal that can send according to intermediate station judges whether the main intermediate station of user terminal exists idle logic channel.Reference table 1, table 1 is the CACH information structure diagram of the 24bit in radiofrequency signal, wherein AT(access style, Access Type) for indicating that the state of logic channel is busy or idle; TC(time division multiple access channel, TDMA Channel) for indicating the timeslot number of time division multiple access channel, described timeslot number is logical channel number, for representing which logic channel in specifically multiple logic channel, LCSS (Link Control Start/Stop, the beginning that link controls or end instruction) is used to indicate beginning or the end of communication.
| AT(1bit) | TC(1bit) | LCSS(2bit) | Correction bits (3bit) | CACH signaling (17bit) |
Table 1
Two logic channels are comprised for each channel, according to shown in table 1, the described concrete deterministic process judging whether the main intermediate station of described user terminal exists idle logic channel can be: each channel comprises two logic channels, like this, two CACH information will be comprised in the radiofrequency signal that the main intermediate station of described user terminal sends, correspond respectively to two logic channels that main intermediate station comprises, when the intensity of radiofrequency signal is greater than pre-determined threshold, user terminal just can to judge in main intermediate station whether available free logic channel according to the numerical value of the AT bit in CACH information, according to the regulation of ETSI-DMR standard, if AT bit is set to 1, then represent that the logic channel that it indicates is busy, namely intermediate station just transfer from except described user terminal other terminal initiate voice communication or transfer of data, if AT bit is set to 0, then represent that the state of its logic channel indicated is idle, namely intermediate station is not in any voice communication of transfer or transfer of data, but issuing idle frame and indicate described user terminal can initiating communication.
If the AT bit in two CACH information is 1, then illustrate that main intermediate station does not have available free logical channel, if the AT bit in two CACH information has one not to be 1, then illustrate that main intermediate station has available free logical channel; User terminal to be determined in main intermediate station after available free logic channel according to the AT bit in CACH information, further, according to the TC bit in corresponding CACH information, described user terminal just can determine that the state of which logic channel is idle, then described user terminal uses described free logical channel to communicate.
The logic channel that the main intermediate station of user terminal comprises can also be divided into main channel and auxiliary channel by the present embodiment, and wherein, a corresponding main channel of main intermediate station, other logic channels are called auxiliary channel.When user terminal triggered communication, first judge whether the main channel in the main intermediate station of described user terminal is in idle condition, if described main channel is in idle condition, then described user terminal uses described main channel to communicate; Otherwise judge whether the main intermediate station of described user terminal exists idle auxiliary channel, described user terminal uses idle auxiliary channel to communicate.
In practical application, the member of same communication set is assigned to same intermediate station usually, and many logic channels comprised using described intermediate station are respectively as main channel.
In the present embodiment, the intermediate station any one being comprised idle logic channel is defined as the free intermediate station of described distributed type assemblies communication system.Each distributed type assemblies communication system only includes a free intermediate station, and described free intermediate station comprises the logic channel of at least one free time.
When the main intermediate station of described user terminal does not exist idle logic channel, described user terminal uses the logic channel of the free time of described free intermediate station to communicate, and the use of free intermediate station can support more calling party further.
The present invention not only can support the system of single website, also can support multi-site system.For multi-site system, the present invention only needs the intermediate station connected with IP in different website.
In the present embodiment, whether the radiofrequency signal that the main intermediate station that described user terminal detects him sends is less than pre-determined threshold, if the radiofrequency signal that described main intermediate station sends is less than pre-determined threshold, then illustrate that described main intermediate station enters sleep state, described user terminal sends main intermediate station described in wake-up signal wakes.Described user terminal is while transmission wake-up signal, can start and wake timer up, the described timer that wakes up is designated as first timer, if receive the feedback signal that main intermediate station sends before first timer time-out, namely show that main intermediate station is successfully waken up, designate in wherein said feedback signal described user terminal can free logical channel, then described user terminal uses described free logical channel to carry out communicating, and described feedback signal is described idle frame.
If do not receive the feedback signal that main intermediate station sends before first timer time-out, then illustrate that described user terminal wakes failure up.Now, described user terminal can use the logic channel of any one free time of free intermediate station to communicate.
If when described free intermediate station is also in sleep state, described user terminal can send free intermediate station described in wake-up signal wakes, and be waken up successfully at described free intermediate station, described user terminal uses the logic channel of any one free time in described free intermediate station to communicate.
When all logic channels in described distributed type assemblies communication system are all in busy state, described user terminal preferentially monitors the main intermediate station of described user terminal.
In practical application, when user terminal is monitoring the main intermediate station of himself, may detect that other intermediate stations forward the calling of this user terminal, now, described user terminal can use this intermediate station forwarding this calling to access this calling.
When the end of calling that described user terminal accesses, whether the main intermediate station that described user terminal can detect himself exists idle logic channel, and if so, described user terminal preferentially monitors described main intermediate station.
