Description
Technical field
The present invention relates to wireless communication field, particularly group calling technology.
Background technology
, there is wireless trunking communication system in the development along with wireless communication technology.Trunked communication system is a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be widely used in the units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, be generally used for meeting the needs of constituent parts intercommunication.So-called trunked communication system, in general be that all users that available channel that system has can be system share, system has automatic selective channel function, and it is the multipurpose of shared resource, contribution, shared channel equipment and service, dynamical wireless dispatching communication system.
The basic service of modern trunked communication system is introduced a kind of new type of call conventionally: group calling.Group-calling service comprises voice group call service (Voice group call service is called for short " VGCS "), and Voice Broadcast Service (Voice broadcast service is called for short " VBS ").
The feature of group calling is that a plurality of user terminals participate in a calling simultaneously, adopts half-duplex operation mode; Each cluster group comprises a group identifier (Group ID) and group call region, wherein organize the corresponding a plurality of user terminals of identifier, and group call region is defined as gang community, these information are stored in attaching position register (Home Location Register when user opens an account, be called for short " HLR ") and Subscriber Identity Module (Subscriber Identity Module, abbreviation " SIM ") in.When initiating group calling/broadcast & call, system is broadcast announcement message (this region is called group call region) in certain regional extent, and the user terminal in group call region can be linked into group-calling channel like this, participates in this group calling/broadcast & call.After group calling promoter speech finishes, other user terminals in listen state can (adopt a continuation method that pushes to talk (Push To Talk) by robbing up operation, be called for short " PTT ") acquisition speaking right, robbing up operation carries out according to the mode of " First come first served ", who first gets and speaks whom, and other add the user terminal of this group-calling service to only have when up just can continue to rob up operation when idle.
The member who participates in group calling/broadcast & call can comprise two classes: dispatcher and service-user.Each group calling/broadcasting service can have at most 5 dispatchers in calling out, only permit at any time 1 service-user and at the most 5 dispatchers talk simultaneously.The dispatcher that VGCS calls out can be fixed-line subscriber or mobile subscriber, and the designated lane that is its foundation by network participates in the Speech Communication of group calling, without robbing up operation, can participate at any time speech.The service-user that participation VGCS calls out i.e. the mobile subscriber of signing VGCS business, and called service user participates in the Speech Communication of group calling by the group-calling channel in group call region.
Service-user in listen state can be by robbing up one operation (the Push To Talk that pushes to talk, be called for short " PTT ") acquisition speaking right participation speech, robbing up operation carries out according to the mode of " First come first served ", who first gets and speaks whom, and other service-users only have when up just can continue to rob up operation when idle.Dispatcher has the designated lane of oneself.
Relate to the group calling of a plurality of MSC, one of them MSC is responsible for the management of calling out, preserve the main attribute of this group calling, we are referred to as Anchor MSC (or being referred to as MSC-A), other MSC is Relay MSC (or being referred to as MSC-R), preserves the cell list of this group calling correspondence under this MSC.Anchor MSC is responsible for setting up all connections, is included in the connection of the designated cell of this MSC, relevant Relay MSC and dispatching desk, and passes through the distribution that a meeting bridge completes speech.Relay MSC only needs to set up a link to Anchor MSC, and Relay MSC is responsible for the distribution of affiliated subdistrict down voice.
At present, Channel distribution mode for group-calling service, comprise, the first group-calling service Channel distribution mode, feature is that group calling speech service-user still takies group-calling channel, speech service-user is monopolized the up of group-calling channel, and in Yu Gai community, other group calling user shares the descending of group-calling channel.In this manner, in group call region, each community only has a Traffic Channel, and that is exactly group-calling channel.This Channel distribution mode is referred to as 1.0 Channel distribution modes in the existing digital clustering communication system GT800 digital cluster system based on global mobile system (Global System for Mobile, abbreviation " GSM ").The method of salary distribution of the second group-calling service channel, feature is that group calling speech service-user takies a Dedicated Traffic Channel of other distribution in speech process, and the up free time of group-calling channel, the descending of group-calling channel shared by other group-calling service user.In this manner, the community of the service-user of not talking in group call region only has a Traffic Channel (both group-calling channels), and in the community at speech service-user place, has two Traffic Channels, and one is group-calling channel, and one is dedicated channel.This Channel distribution mode is referred to as 1.5 Channel distribution modes in the existing digital clustering communication system GT800 digital cluster system based on GSM.
Due to the difference of the method for salary distribution of above-mentioned two kinds of group-calling service channels, these two kinds of Channel distribution modes also have different features in function application.Take GT800 group system as example, and there is different features in so-called 1.0 Channel distribution modes and 1.5 Channel distribution modes, as follows in function application:
(1) due under 1.0 Channel distribution modes, spoken user and other service-user shared channel, the speech of oneself may be sent back on group-calling channel, so meeting echogenicity; And 1.5 Channel distribution modes can be avoided this problem;
(2) for some particular services, caller priority for example, group calling short data, need to service-user and network except current speech service-user can carry out Signalling exchange fast, in order to meet time performance requirement, can only under 1.5 Channel distribution modes, carry out.Because under 1.5 Channel distribution modes, speech service-user does not take the up of group-calling channel, and the up of group-calling channel can send for other user's signaling.
In prior art, network can at any time be transformed into dedicated channel speech service-user from group-calling channel, also can from dedicated channel, be transformed into group-calling channel at any time; That is to say, current group calling is decided in its sole discretion by network completely the channel type using, and operator or user cannot arrange in advance.
In the invention process, inventor finds that in prior art, at least there are the following problems, take GT800 group system as example: prior art does not have the control flow of clear and definite group-calling service channel, cause mobile services switching centre (Mobile Switching Centre, abbreviation " MSC ") processing and between base station controller (Base Station Controller is called for short " BSC ") may be inconsistent.The group-calling service channel controling mode in GT800 trunked communication system of take is example, if MSC wishes to adopt 1.5 Channel distribution modes, at speech service-user, take and uply rear it is assigned to a dedicated channel, and BSC may discharge this dedicated channel at any time, allow speech service-user join group-calling channel.1.0 Channel distribution modes have been become so again.And MSC assigns to dedicated channel group calling user, cause endless loop.
During switch this inconsistent minizone that is also embodied in speech service-user, if switched, occur in BSC inside, the channel allocation of switching target small area depends on BSC so, BSC can be switched to speech service-user on the group-calling channel of new community (i.e. 1.0 Channel distribution modes), also can newly distribute in Target cell a dedicated channel, and then be switched to (i.e. 1.5 Channel distribution modes) in dedicated channel.
In addition, for some, there is particular service (speaker priority for example, group calling short data) the group calling group of demand, the group calling that requires this group of system held channel allocation remain on 1.5 Channel distribution modes, if the method for salary distribution of group-calling service channel is uncontrollable, can not meet the performance requirement of particular service.

Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment mono-:
Refer to Fig. 1, Fig. 1 is the exemplary process diagram of the control method of the group-calling service that discloses of the embodiment of the present invention.This flow process comprises the following steps:
Step 101: the priority that network side requires group-calling service Channel distribution mode separately according to group calling Zu He community is determined group-calling service channel assignment strategy.
Network side can set in advance the requirement of group calling group to the group-calling channel method of salary distribution as required, and the requirement of community to the group-calling channel method of salary distribution; The precedence information that group calling Zu He community requires the group-calling channel method of salary distribution separately also can be set simultaneously.
If in the time of the priority that the priority that group calling group requires group-calling service Channel distribution mode requires group-calling service Channel distribution mode higher than community, network side just preferentially requires to carry out channel allocation according to described group calling group to group-calling service Channel distribution mode; If the priority that the priority that community requires group-calling service channel allocation requires group-calling service Channel distribution mode higher than group calling group, network side preferentially requires to carry out group-calling service channel allocation according to community to group-calling service Channel distribution mode so.
Further, particularly, determine that group-calling service channel assignment strategy can be also: whether be particular channel distribute requirement, it can be group calling 1.5 channel allocation requirements in group-calling service that the particular channel here distributes requirement if according to the Channel distribution mode of group calling group or community, requiring.Method is as follows:
When the group-calling channel method of salary distribution of described group calling group is that particular channel distributes requirement, simultaneously, the group-calling channel method of salary distribution of described community is not that particular channel distributes while requiring, the group-calling channel method of salary distribution according to group calling group requires to distribute group-calling channel, also according to group calling 1.5 channel allocation requirements, be the group-calling channel of group calling user assignment special use;
The group-calling channel method of salary distribution when described community is that particular channel distributes requirement, simultaneously, the group-calling channel method of salary distribution of described group calling group is not that particular channel distributes while requiring, according to the group-calling channel method of salary distribution of community, require to distribute group-calling channel, also according to group calling 1.5 channel allocation requirements, be the group-calling channel of group calling user assignment special use;
The group-calling channel method of salary distribution when described community is that particular channel distributes requirement, meanwhile, the group-calling channel method of salary distribution of described group calling group is also that particular channel distributes while requiring, so, according to described particular channel, distributing and require to distribute group-calling channel, is the group-calling channel of group calling user assignment special use;
The group-calling channel method of salary distribution when described community is not that particular channel distributes requirement, simultaneously, the group-calling channel method of salary distribution of described group calling group neither be distributed while requiring by particular channel, now, community and group calling group all do not have specific (special) requirements to the distribution of group-calling channel, network side is that current group calling distributes group-calling channel according to the mode of acquiescence so, also according to Channel distribution mode more common in current group-calling service: group calling 1.0 Channel distribution modes carry out channel allocation.
Step 102: according to described group-calling service channel assignment strategy allocated channel.
The method that group-calling service that the present embodiment one discloses is controlled, can be used in and initiate group calling or group-calling service CU up time, carries out described group-calling channel distribution in current area; Also can be used in when group calling switches, carry out described group-calling channel distribution.
Further:
When group-calling service is initiated, for preferentially meeting the special channel type requirement of group calling group, MSC is in group call establishment, according to group, specifying the Channel distribution mode of group call channel type requirement/group calling group to require sign to judge that corresponding group calling is whether having the requirement of allocated channel type, if there is special channel type to require, is that group calling is distribution group-calling channel according to the group call channel type of group acquiescence group call channel type indicated value indication; Otherwise MSC search community acquiescence group call channel type indicated value and by the channel type of this value indication be group calling distribution group-calling channel, if MSC can not obtain community, give tacit consent to group call channel type indicated value, assigned at random group call channel type.If preferentially meet cell channel allocation optimized, MSC is in group call establishment, MSC first searches community acquiescence group call channel type indicated value and is that group calling is distribution group-calling channel by the channel type of this value indication, if community acquiescence group call channel type does not preset, further according to the default channel type indicated value of corresponding group calling group, distribute group-calling channel, if group calling group default channel type does not preset yet, MSC assigned at random group call channel type.
When group calling switches, if current speech service-user switches, the group-calling channel pattern value of switching target small area is determined by place, Target cell MSC.For preferentially meeting the special channel type requirement of group calling group, the process of MSC value can be: MSC requires indicated value to judge that corresponding group calling is whether having the requirement of allocated channel type according to group allocated channel type, if there is special channel type to require, and the channelling mode that the group call channel type of getting the indication of group default set calling channel type indicated value is Target cell; Otherwise the channelling mode that the group call channel type of MSCQu community acquiescence group call channel type indicated value indication is Target cell, if MSC can not obtain community acquiescence group call channel type indicated value, assigned at random group-calling channel.If preferentially meet cell channel allocation optimized, the process of MSC value is as follows: the channelling mode that the group call channel type of MSCQu community acquiescence group call channel type indicated value indication is Target cell, if community acquiescence group call channel type indicated value, the channelling mode that the group call channel type that does not preset and then get the default channel type indicated value indication of corresponding group calling group is Target cell, if group calling group default channel type does not preset yet, MSC assigned at random group call channel type.
In above-mentioned processing procedure, MSC can be specifically Anchor MSC and Relay MSC.
The scheme disclosing by the present embodiment one, can be so that group calling Zu He community separately can be according to priority to Channel distribution mode requirement, or whether exist special channel to distribute and require Coordination Treatment, thereby make the distribution of group-calling service channel controlled, thereby also meet the demand of particular service.
