Description
Technical field
The present invention relates to wireless communication field, particularly group calling access technology.
Background technology
Trunked communication system is a kind of mobile communication system that is used for group's dispatch control communication, is mainly used in professional moving communicating field.It is shared that the available channel that this system has can be all users of system, and it is the multipurpose of shared resource, contribution, shared channel equipment and service, dynamical wireless dispatching communication system.
Trunking communication is adopted the work of shared channel half-duplex mode as a kind of senior mobile command dispatching patcher, and number of users is not limit in the group.Trunking communication provides abundant type of service, comprises that individual calling, group calling, function addressing, dynamically reorganization, multipriority, distant getting killed/activates, environment are intercepted, group service characteristics such as fail soft, VPN, End to End Encryption, terminal are led directly to, location, group note.Wherein the multipriority business is a kind of important business model of cluster application.Current cluster mainly adopts arrowband time division multiple access (Time DivisionM ultiple Access, be called for short " TDMA ") standard, main IDEN (integrated digital enhanced network), TETRA (Terrestrial trunked radio), the GT800 etc. of comprising.
At present, group-calling service has voice group call service (Voice group call service is called for short " VGCS "), and it is a kind of telecommunication service.Group-calling service has defined a kind of by participating in (mobile subscriber or fixed-line subscriber) in many ways, wherein the synchronization one-man point-to-multipoint voice communication mode that can talk, listen in many ways.VGCS is professional just to exhale the member of all these groups with a group function code (group ID), participate in subscriber equipment (the User Equipment of same VGCS communication, be called for short " UE ") can be distributed in a plurality of cellular cells, in addition, VGCS also the supporting business user realize transformation between speaker and the hearer's identity.The VGCS business has broken through the limitation of point-to-point communication, can set up group call in simple and direct mode, realizes specific functions such as dispatch control, emergency notice, is particularly useful for the train traffic control traffic department of railway.
In trunked communication system, by strengthening multipriority and seizing business (enhanced Multi-LevelPrecedence and Pre-emption, be called for short " eMLPP ") can realize: when putting, UE1 exhales in the communication process, this moment, other UE initiated to comprise the group calling of UE1, system can send a notification message on the FACCH of active user's busy channel (Fast Associated Control Channel) so, UE1 receives after this notification message, can select to withdraw from ongoing point and exhale to join in the group calling and go, also can select to ignore group calling and continue ongoing point and exhale.
But, adopt the eMLPP business realizing putting and exhale the user will cause the slow problem of response speed of UE to the scheme of group calling user conversion.This be because, after UE receives the notification message of group calling, need inquire whether the user is linked in this group calling by man-machine interface, being selected by the user is to withdraw from ongoing point to exhale to join in the group calling and go, and still ignores group calling and continues ongoing point and exhale; The perhaps setting by automatic priority, judgement are to withdraw from ongoing point to exhale to join in the group calling and go, and still ignore group calling and continue ongoing point and exhale.If decision is to withdraw from ongoing point to exhale and join in the group calling, then need this UE to carry out the channel that a point exhales earlier and discharge flow process, the access process that carries out a group calling again, therefore, the response speed of UE is slower.
On the other hand, if mobile phone is not provided with auto-pickup priority, can select whether to answer for the group calling of any priority so, so just can not embody group calling advantage aspect command scheduling, and, also can't avoid fully because artificial misoperation is ignored and transferred the very high group calling of priority.
Summary of the invention
The technical problem underlying that each execution mode of the present invention will solve provides a kind of group call channel access method, system and equipment, makes that putting the UE that exhales can be linked into group-calling channel rapidly and accurately.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In embodiments of the present invention, network side need be when putting the UE that exhales and initiate group calling, and whether the priority of judging earlier this group calling greater than presetting thresholding, if, then be used for the message that point of release is exhaled, and in this message, carry the channel descriptor of this group calling to this UE transmission.After this UE receives this message, discharge the channel that ongoing point is exhaled, and describe this group-calling channel of access according to the channel in this message.
Below first execution mode of the present invention is elaborated, present embodiment relates to group call channel access method, and idiographic flow as shown in Figure 1.
In step 110, when network side need judge that whether the priority of this group calling is greater than presetting thresholding earlier when putting the UE that exhales and initiate group calling.Specifically, network side can set in advance the thresholding of a priority, as at (the Mobile Switch Center of mobile switching centre, be called for short " MSC ") in be provided with, when need be when put the UE that exhales and initiate group calling, elder generation judges that whether the priority of this group calling is greater than the thresholding that sets in advance, if the priority of this group calling presets thresholding greater than this, then enter step 120, otherwise, direct process ends.
In step 120, network side sends to this UE and is used for the message that point of release is exhaled, and carries the channel descriptor of this group calling in this message.Specifically, in the present embodiment, being used for the message that point of release exhales is Channel Release message, describes (Group Channel Description) information element by the group-calling channel in this Channel Release message and carries the channel descriptor of this group calling, as shown in table 1.
Table 1
Because Channel Release message is to be used for the message that channel discharges in the prior art, therefore, when the priority of network side judgement group calling is prescribed a time limit greater than preset gate, directly known group-calling channel descriptor is filled into and is used for the Channel Release message that point of release is exhaled, so that directly realize present embodiment on the basis of existing technology, ensured the smooth evolution of prior art.Channel Release message can send to this UE by the FACCH channel.
Then, enter step 130, this UE receives this message.That is to say that this UE receives the Channel Release message that comprises the group-calling channel descriptor on the FACCH channel.
Then, enter step 140, this UE point of release is exhaled channel, and describes the access group calling channel according to the channel in the Channel Release message of receiving.
Because in existing trunking communication, when the network side need are initiated group calling to putting the UE that exhales, notify this UE relevant group calling information by on the FACCH channel, sending the group calling notification message, whether be linked in this group calling by man-machine interface inquiry user by UE; The perhaps setting by automatic priority, judgement are to withdraw from ongoing point to exhale to join in the group calling and go, and still ignore group calling and continue ongoing point and exhale.And in the present embodiment, after this UE received Channel Release message, unconditionally point of release was exhaled channel, and described the access group calling channel according to the channel of the group calling in this message.That is to say, network side is directly by a Channel Release message, exhale professional UE to be linked in the group-calling channel with putting, make this UE need not to carry out earlier the release flow process that a point is exhaled, carry out the access process of a group calling again, effectively reduce point and exhale the connecting time of group calling, make the group calling of the quick unconditional response high priority of UE, give full play to the advantage of group calling command scheduling in trunking communication.
Because network side is before sending the Channel Release message of carrying the group-calling channel description to this UE, the priority of this group calling is judged, for the group calling that is equal to or higher than certain priority, just send this Channel Release message, group-calling channel is arrived in UE incoming call unconditionally to this UE.Avoided being provided with the risk of auto-pickup by UE.Such as because the priority of group calling is very high, the user wishes that this UE answers group calling and exit point is exhaled, but because the error of manual operation has selected to ignore this group calling.
Second execution mode of the present invention relates to group call channel access method, and the present embodiment and first execution mode are roughly the same, and its difference only is that the content information that Channel Release message carries is slightly different.The content information that Channel Release message in the present embodiment is carried, in the first embodiment on the basis of the content information that carries of Channel Release message, group call reference (CallReference), priority (Priority) information have further been increased, this Channel Release message is carried the reference information and the precedence information (being used to represent that the information element of reference information and precedence information is defined as prior art) of group calling by the field of expansion, and is as shown in table 2.
