Abstract
The method includes following steps: (1) in 0808 protocol, two channel assignation modes of sub zone in group calling area are added in order to expand the protocol; (2) based on expanded protocol, mobile switch center carries out data configuration for channel allocation mode of sub zone in group calling area of voice cast service; (3) based on the said data configuration, subsystem of base station sends out message of downward detection; based on whether there is downward user, controller of base station determines whether group calling channel is released. Expanded 0808 protocol supports function of downward detection of VBS call. Thus, allocation of group calling channel is carrier out for VBS call only when users need it; otherwise, system will release group calling channel no user uses. Group calling channel for VBS call is distributed according to need. Advantages are: saving resources, raising use ratio of GSMR/GT800 system.
Description
Technical field
The present invention relates to a kind of method of calling channel utilance and agreement of expansion of improving, the invention particularly relates to a kind of method of the calling channel utilance that improves Voice Broadcast Service and the GSM0808 agreement of expansion.
Background technology
According to the different characteristics of customer group, mobile communication can be divided into public mobile communication and specialized mobile radio.Specialized mobile radio is mainly the inner use of each specialized department, and there are different separately frequencies, different business and network demand separately in each specialized department.Entered since the nineties, along with the development of digital public mobile communication, the digital private mobile communication also draws attention gradually.European railway alliance (UIC) in 1993 decision is with the basic platform of GSM as the following railway mobile communication business in Europe, ETSI moves especially in group (ETSI SMG exists) GSM phase 2+ standard and has introduced advanced speech call (ASCI), the basic function that specifically comprises priority service, voice broadcast call business (VBS), speech group-calling service specialized mobile radios such as (VGCS), and it is applied to railway, be referred to as GSM-R.
GT800 (GSM TRUNK 800M), it is the 800M GSM of Huawei Company cluster communication system, it is based on the GSM platform, the digital cluster system that has independent intellectual property rights, the GT800 system is except possessing above-mentioned ASCI basic function, the ability of cluster common network operation also is provided, has adapted to the development need of building the cluster common network from now on.The GT800 system can carry out the scheduling of class private network on the common network basis, mandate department can carry out the scheduling of the trans-departmental private network of emergency cooperative.
The voice group call service of GT800/GSMR system (VGCS) provide a kind of half-duplex communication mode.Be characterized in that in communication process synchronization has only a user to talk, other user who is in the group call region is in the state of listening, the authority that the user can obtain to talk by PTT push to talk mode (PTT).Voice broadcast call business (VBS) is similar to voice group call service, is characterized in whole communication process, has only the promoter to talk, and other user is in the state of listening; Call out for VGCS and VBS, when calling out initiation, mobile switching centre (MSC) issues VGCS/VBS assignment request (Assignmnet Request) message can for each sub-district in the group call region, and base station sub-system (BSS) is that group calling distributes a channel in each sub-district of group call region according to the group-calling channel method of salary distribution that indicates in this message; The resource utilization that a bottleneck of GT800/GSMR system is a system is lower, call out for VBS in the current agreement, can utilize the delay assignment function to improve the utilance of resource: promptly, when the initial VBS of initiation calls out, each sub-district at group call region is not distributed group-calling channel immediately, if this group call region has downlink user to monitor, then come at this cell allocation group-calling channel by the push-notification-answer flow process.But there is following shortcoming in this technology: the delay assignment function only determine the moment of initiating group calling whether at group call region cell allocation group-calling channel, after group-calling channel has been distributed by delay assignment in certain sub-district, if the descending monitoring users of this sub-district is the leaving group-calling zone all, this group-calling channel is not still keeping not release, owing to use without any the user, be a kind of waste this moment for this channel.
In another prior art, call out for VGCS, provide a kind of descending detection method to come multicall channel releasing in existing 0408 agreement, promptly when BSS detects certain sub-district and do not have the user to be in listening state on group-calling channel, will discharge this channel.Only be applied to VGCS and call out but be to use to offer some clarification in the agreement of this method, and the method for salary distribution of group-calling channel is necessary for " immediately and resource can discharge (Immediate and the resources may further be de-allocated by theBSS) ", sub-district for user behind the distribution group-calling channel under the delay assignment situation leaves again can not discharge channel automatically.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, and then provide a kind of method of the channel utilization that Voice Broadcast Service calls out and 0808 agreement of expansion of improving, described method is called out for VBS, accomplish the distribution according to need of group-calling channel, when the sub-district of having only that and if only if has the user to use group-calling channel, just distribute or keep corresponding group-calling channel, otherwise system does not distribute or discharge the group-calling channel that has distributed automatically, improves the channel utilization of system so to greatest extent.
According to an aspect of the present invention, improve the method for Voice Broadcast Service calling channel utilance in a kind of mobile communication system, comprising: 1). in 0808 agreement, the channel assignment pattern by increasing by two kinds of group call region sub-districts is to expand described agreement; 2). described 0808 agreement after mobile switching centre is according to expansion is carried out data configuration to the channel allocation mode of Voice Broadcast Service group call region sub-district; 3). according to described data configuration, base station sub-system issues descending detect-message, and whether base station controller is according to having downlink user to determine whether multicall channel releasing.
According to another aspect of the present invention, the invention provides a kind of method of expansion 0808 agreement, described agreement comprises the channel assignment pattern of group call region sub-district: postpone allocation model, assignment immediately and resource can not release modes, but assignment immediately and resource release mode, it is characterized in that, in the channel assignment pattern of described group call region sub-district, increase by first pattern and second pattern, described first pattern is used to represent when initiating the Voice Broadcast Service calling, base station sub-system distributes group-calling channel can for each sub-district immediately, but distribute group-calling channel according to the push-notification-answer message of the monitoring users of each sub-district, when base station sub-system detects the sub-district of having distributed group-calling channel and does not have the user, to discharge this channel automatically, described second modal representation is when initiating the Voice Broadcast Service calling, base station sub-system can be given the group-calling channel of each cell allocation in the group call region, when this sub-district does not have the user, use descending detection technique to discharge the group-calling channel that distributes automatically.
In the present invention, by expansion to 0808 agreement, supported the descending measuring ability that VBS calls out, make and call out that only the ability assign group is exhaled channel when having the user to need, otherwise system will discharge the group-calling channel that does not have the user to use automatically for VBS, make and call out the distribution according to need of having accomplished group-calling channel for VBS, saved resource, improved the channel utilization of GSMR/GT800 system, will bring actual economic benefit for operator.
Brief Description Of Drawings

Embodiment
Below in conjunction with accompanying drawing the method for a kind of calling channel utilance that improves Voice Broadcast Service of the present invention and 0808 agreement of expansion are described in detail.
Figure 1 shows that the AssignmentRequirement field of the method for salary distribution of expression group-calling channel in 0808 agreement.As shown in Figure 1, in 0808 agreement, the Assignment Requirement field of message VGCS/VBSASSIGNMENT REQUEST is represented the method for salary distribution of group-calling channel, promptly, value with the Octet2 of field Assignment requirement defines group calling channel allocation mode, definition has three kinds of group-calling channel methods of salary distribution in existing 0808 agreement, Dui Ying Octet2 is 0x00 respectively, 0x01 and 0x02, wherein when the Octet2 of Assignment requirement value is 0x00, the group-calling channel of this sub-district is the delay assignment pattern, promptly have only when there is downlink user this sub-district in the moment of initiating voice broadcast call, just can distribute group-calling channel, when the Octet2 of Assignmentrequirement value is 0x01, the group-calling channel pattern of this sub-district is assignment immediately, but do not allow base station sub-system (BSS) system to discharge channel by descending detection, when the Octet2 of Assignmentrequirement value is 0x02, the group-calling channel pattern of this sub-district is assignment immediately, but allow the BSS system to discharge channel by descending detection, when its value is 0x02, only VGCS is called out effectively.
In order to realize that VBS call out is saved channel resource, and with original protocol-compliant, the present invention expands existing 0808 agreement.Wherein, for two kinds of values definition of Octet2 increase of Assignment requirement, the Octet2 value that promptly increases Assignment requirement is 0x09 and 0x0A.When the Octet2 of above-mentioned Assignment requirement value is 0x09, the group-calling channel method of salary distribution that expression VBS calls out is that assignment of VBS call delay and resource can be discharged by BSS, in other words, when Assignment requirement value is 0x09, the group-calling channel of this sub-district postpones to distribute, and allows BSS to discharge the group-calling channel that VBS calls out by descending detection; When the Octet2 of above-mentioned Assignment requirement value is 0x0A, the group-calling channel pattern that expression VBS calls out is that VBS calls out assignment immediately and resource can be discharged by BSS, just when the Assignmentrequirement value is 0x0A, the group-calling channel of this sub-district distributes immediately, and allows BSS to discharge the VBS group-calling channel by descending detection.Will be appreciated that, the Octet2 of Assignment requirement can also get other value, say in principle, as long as and the front do not repeat just passable, in the present embodiment, getting 0x09 and 0x0A mainly is to consider that agreement itself has expansion, has reserved some value definition for the expansion of agreement itself.
Fig. 2 calls out the realization flow frame of descending detection multicall channel releasing for the VBS of the embodiment of the invention, as shown in Figure 2, method in the calling channel utilance that realizes raising Voice Broadcast Service of the present invention is at first carried out the expansion of above-mentioned 0808 agreement, and the agreement after mobile switching centre (MSC) is according to described expansion is carried out data configuration to the calling channel of Voice Broadcast Service group call region sub-district, be newly-increased three attributes in each sub-district of VBS group call region in an embodiment of the present invention: " descending detect-message issues number of times " attribute, " descending detect-message issues blanking time " attribute and " whether supporting the descending detection that VBS calls out " attribute, wherein when the value of " descending detect-message issues blanking time " attribute is configured to 0, descending measuring ability is closed in expression, " whether support VBS call out descending detection " attribute be for original protocol-compliant, it controls the method for the calling channel utilance of whether using raising Voice Broadcast Service of the present invention as a switch.After by the agreement after mobile switching centre is according to described expansion the calling channel of Voice Broadcast Service group call region sub-district being carried out data configuration, the channel assignment pattern of group call region of the present invention sub-district is: postpone to distribute (DelayAllowed) pattern, assignment immediately and resource can not discharge (ImmResNotDealloc) pattern, assignment immediately and resource can discharge (ImmResDealloc) pattern, and assignment of VBS call delay and resource can discharge (VBSDelayDealloc) pattern and VBS assignment immediately and resource can discharge (VBSImmResDealloc) pattern.When VBS calls out initiation, MSC issues VGCS/VBSAssignment Request message can for each sub-district in the group call region, BSS will distribute a channel according to the group-calling channel method of salary distribution that indicates in this message for group calling in each sub-district of group call region, in an embodiment of the present invention, for the cell allocation group-calling channel pattern setting of VBS group call region comprises VBSDelayDealloc pattern and two kinds of situations of VBSImmResDealloc pattern, for the situation of VBSDelayDealloc pattern is when the data configuration of MSC, the Octet2 of Assignment requirement is changed to 0x09, this moment is when initiating the VBS calling, the BSS system can give the group-calling channel of each cell allocation in the group call region, when this sub-district does not have the user, use descending detection technique to discharge the group-calling channel that distributes automatically, for the situation of VBSImmResDealloc pattern is when the data configuration of MSC, the Octet2 of Assignment requirement is changed to 0x0A, this moment is when initiating the VBS calling, the BSS system distributes group-calling channel can for each sub-district immediately, but distribute group-calling channel according to the push-notification-answer message of the monitoring users of each sub-district, when the BSS system detects the sub-district of having distributed group-calling channel and do not have the user, will discharge this channel automatically.
In the cell allocation of VBS group call region behind the group-calling channel, the value M that the property value of attribute " descending detect-message issues number of times " is set to be scheduled to, wherein the value of M is 4 in the present embodiment, attribute " descending detect-message issues blanking time " property value be set to 3 and attribute " whether support VBS call out descending detection " property value be set to be, promptly represent the current descending detection (step s001) of supporting that VBS calls out that is provided with, in the cell allocation of VBS group call region during group-calling channel, different sub-districts can be configured to different, a group call region comprises a plurality of sub-districts, but what these sub-districts had can be configured to delay assignment and resource release mode, but what have can be configured to assignment immediately and resource release mode, then, above-mentioned base station sub-system (BSS) judges whether current setting supports the descending detection that VBS calls out, whether the property value of promptly judging above-mentioned attribute " whether support VBS call out descending detection " non-zero (step s002), if the judged result of above-mentioned steps s002 is the descending detection of supporting that VBS calls out, judge further then whether above-mentioned attribute " descending detect-message issues blanking time " property value is zero (step s003), if the result who judges in step s003 is attribute " descending detect-message issues a blanking time " property value non-zero, then above-mentioned BSS issues descending detect-message and with the number of repetition of descending detect-message add up (step s004), then base station controller (BSC) judges whether to receive that hearer that base station (BTS) reports detects replys (Listener Detect) message, wherein, Listener Detect has detailed regulation in existing 0408 agreement, here do not giving unnecessary details.Above-mentioned BSS system issues descending detect-message at regular intervals, if have portable terminal (as, mobile phone) monitoring the descending of group-calling channel, then above-mentioned portable terminal can be sent out to BTS and insert pulse (Access Burst), BTS receives that the back reports Listener Detect message (step s005) to BSC, if being BSC, the result who judges receives the Listener Detect message that the base station reports in step s005, then the number of times that above-mentioned descending detect-message is issued resets, this kind situation can not multicall channel releasing, and get back to step s004 (step s006), if being BSC, the result who judges do not receive the Listener Detect message that the base station reports in step s005, whether the then further number of times of judging that descending detect-message issues reaches the number of times of configuration, promptly reach property value M (step s007) to the configuration of attribute " descending detect-message issues number of times ", if being the number of times that descending detect-message issues, the judged result in step s007 reaches value M, then BSC discharges the VBS group-calling channel of above-mentioned configuration, make like this when not having portable terminal (as mobile phone) monitoring group-calling channel descending, BSC can not receive the related news that the base station reports, when BSC does not repeatedly receive the message that the base station reports according to data configuration after, just discharge the channel resource (step s008) of this sub-district.
Though above explanation to invention is carried out with reference to its specific embodiment; but those of ordinary skill in the art is to be appreciated that; in connotation of the present invention and scope; various improvement, interpolation and replacement all are possible, and all in the protection range that claim of the present invention limited.
