Detailed description of the invention
The solution of the embodiment of the present invention is mainly: carry the special FACH of cluster in network side configuration
The reservation system of the required configuration information that (Forward Access Channel, forward access channel) is corresponding
Resource Block, UE(user equipment, subscriber equipment, user terminal) by cell searching, resident
Community is opened BCH(Broadcast Channel, broadcast channel) read include reservation system Resource Block with
And the system message of the schedule information of reservation system Resource Block, and successfully carried out community by this system message
Resident；When group-calling service, UE is without carrying out RRC(Radio Resource Control, Radio Resource
Control protocol) connection establishment, group exhale called during, UE sends to network side that to carry calling relevant
All parameters caller set up request message, to obtain the physical resource Information that network side configures for UE,
Carry out group and exhale caller speech business；During group exhales caller, UE is according to joining in reservation system Resource Block
Put the group call resource configuration message that acquisition of information FACH sends, set up corresponding channel resource, carry out group
Exhale called voice service, to shorten the time delay of UE cluster multi call, and then improve Consumer's Experience effect.
The present invention is strict to delay requirement in view of colony terminal, and group-calling service resident in community sets up process
In all carried out respective handling, to adapt to the needs of cluster multi call.
As it is shown in figure 1, one embodiment of the invention proposition is a kind of realizes the resident method exhaled with group of colony terminal,
Including:
Step S101, UE obtains persistent district by cell searching, opens BCH in persistent district and reads
System message, system message at least includes the scheduling letter of reservation system Resource Block and reservation system Resource Block
Breath；
At network side, System information block (SIB) is used for comprising real system message, in the prior art,
SIB including SIB1 to SIB19 totally 19 types.The schedule information of SIB is carried by MIB or SB.
Wherein, system message is at BCCH(BCCH, Broadcast Control Channel) upper transmitting,
Then it is mapped to BCH or FACH, and always matches with BCH or FACH transport block size.
In order to make UE success persistent district, and in follow-up group-calling service, reduce time delay, the present embodiment network
A System information block, i.e. reservation system Resource Block alleged by the present embodiment are newly established in side, with SIB30 table
Showing, this SIB30 carries required all configuration informations that the special FACH of cluster is corresponding.
System message broadcast MIB(master scheduling block) in broadcast system message block SIB30, certainly,
Can also broadcast in Scheduling Block SB1 or SB2, specifically with the foundation that is embodied as of network side, but
UE is required to process and broadcasts at any one of three kinds of system scheduling message blocks.
UE is in start process, first according to specifying frequency to carry out cell searching, if searching community, then
Open BCH read system message in the cell, attempt resident.
If specifying frequency not find community, or resident failure, then carry out full frequency band frequency sweep, root
According to frequency sweep result, then carry out cell searching, then according to the signal intensity of cell searching from high to low suitable
Sequence is read out system message, and attempts resident on the community searched.
Step S102, carries out little according to the schedule information of reservation system Resource Block and reservation system Resource Block
District is resident.
Judge resident during, SIB30 must be at master scheduling block, or Scheduling Block SB1 or SB2
In be scheduled, otherwise it is assumed that UE is not suitable for resident in this community, SIB30 is specifically on which Scheduling Block
Being scheduled, by network side according to certain regulation arrangement, either which Scheduling Block, UE should connect
It is subject to and processes SIB30.The schedule information of SIB30 requires SIB30 is scheduling, which specify SIB30
Position and the repetition period.
On the premise of judging that SIB30 is scheduled, UE opens BCH and carries out the reception of system message, makees
For the essential SIB of persistent district, including SIB1, SIB3, SIB5, SIB7 and SIB30.As it was previously stated,
UE using SIB30 as essential resident condition because which specify the institute that cluster special FACH channel is corresponding
Having information, do not have these information, persistent district can not be normally carried out group service.
After UE receives the essential system message including SIB30, can successfully reside in cluster community, if
One SIB of any of which does not receive during read system message, and Ze Gai community cannot be resident,
So UE then attempts resident next community, and it judges that resident principle is with previous community.
The present embodiment UE passes through cell searching, opens BCH reading and include reservation system in persistent district
The system message of the schedule information of Resource Block and reservation system Resource Block, this reservation system Resource Block carries
Having required configuration information corresponding for the special FACH of cluster, UE is successfully carried out community and stays by this system message
Staying, the time delay for follow-up group-calling service shortening UE cluster multi call creates basis simultaneously.
As in figure 2 it is shown, another embodiment of the present invention proposition is a kind of realizes the resident side exhaled with group of colony terminal
Method, on the basis of above-described embodiment, also includes after above-mentioned steps S102:
Step S103, reads the configuration information in reservation system Resource Block according to schedule information, and is saved in
Local；
At UE after BCH reads system message, UE removes to read the tool of SIB30 according to schedule information
Internal appearance, and it is saved in this locality, including: the auxiliary public control physical of the special SCCPCH(of storage cluster is believed
Road) configuration information, the TFS of storage cluster FACH and the configuration information of corresponding TCCCH, storage
" the repetition period " of TCCCH, " repetition length " and " Frame offset " cell.
Repetition period represents the PTT GROUP PHYSICAL CHANNEL of carrying on TCCCH
The cycle that CONFIG message sends.UE calculates the initial transmission frame of this message by equation below:
SFN mod repetition period=Frame offset mod repetition period；
Repetition length represents PTT GROUP PHYSICAL CHANNEL in this cycle
CONFIG message continuously repeats the number of times of transmission.If repetition length is configured without, give tacit consent to PTT
GROUP PHYSICAL CHANNEL CONFIG only sends out once in mono-cycle；If repetition
Length is configured to " 2 ", represents and continuously transmits 2 times, and the rest may be inferred for other Configuration Values.Frame offset
It is to ensure that UE knows there is group service after receiving beep-page message (PCH), then can be the fastest
Time on cluster FACH, receive information, without by the time cluster FACH week after date.
Step S104, UE carries out location updating and group information updating；
Resident behind community in UE success, that advanced line position updates registration process, position updating process is tied
Shu Hou, UE actively initiate group information updating process, and this group information updating process is to allow UE to network
Understanding its information being belonged to collection group, network can change the letter of group belonging to terminal according to certain setting
Breath, therefore, each UE, after start successful registration, carries out the renewal process of group information, to obtain
New group information.
Wherein, the position updating process of UE, the function in former TD standard can be used.The most superfluous
State.
For the renewal process of UE group information, UE is after location updating is finished in start, it is necessary to initiate at once
The renewal process of group information, detailed process is:
UE sends PTT information Update Request message (group information updating request message) and arrives
Network side, carries IMSI(International Mobile SubscriberIdentification within the message
Number, international mobile subscriber identity) information, for judging group information belonging to UE for network,
After network receives this message, after judging accordingly to set up with message, send PTT information Update
Accept message (group information updating response message) arrives UE, wherein carries the group information of UE, with
Making UE know current place group, create basic condition for follow-up group of call business, such as a UE can
Can belong simultaneously to multiple group, when carrying out group-calling service, user can select to carry out sending out in certain group
Play calling.
Step S105, sends caller by RACH to network side and sets up request message, and caller is built
Vertical request message carries call related parameters；
Step S106, receives the caller foundation sound that UE is authenticated and returns after collision detection by network side
Answer message, caller to set up response message and carry the physical resource Information that network side is UE configuration；
Step S107, according to the physical resource Information of network side configuration, carries out group and exhales caller speech business.
Above-mentioned steps S105 to step S107 is that UE group exhales caller process, and the present embodiment is in order to contract as far as possible
Short time-delay, does not carry out RRC connection establishment process, directly carries out a group call establishment process, complete UE
With the Signalling exchange of network, obtain traffic channel resource simultaneously, carry out organizing vocative expression sound caller process.
Specifically, for the terminal of normal Standby, its cluster multi call caller process is:
1, UE needs carry out group exhale time, by RACH send PTT Call Setup Request
Message.Exhale the requirement quickly accessed according to group, UE should access in 800ms.Therefore, in order to improve
Access speed, eliminates RRC link setup process eating dishes without rice or wine, will in message PTT Call Setup Request
The all information in Service Request, Setup message in ordinary call all bring, wherein for exhaling
Relevant parameter is made to have CN domain identity, calling identification (P-TMSI or IMSI), called number
Code, qos requirement and call business type etc.；
2, network side is after the group receiving UE transmission exhales caller to set up request, needs authenticate and conflict
After the work such as detection, then confirmation permission user's access, obtain pre-configured physics according to group-calling service type
Resource information, brings UE by PTT Call Setup Response message on FACH channel, takes simultaneously
Band is operation layer 2 configuration index in SIB, and UE carries out phase according to physical layer configurations instruction after receiving this message
Close configuration and with NODE B(base station) dedicated channel synchronizing process；
3, UE is after completing configuration and synchronizing process, returns call setup in uplink service dedicated channel
Completion message；
4, UE opens voice channel, and user can be at the enterprising lang of ascending voice channel resource being assigned to
The up transmission of message breath, it is achieved group exhales caller speech business.
From the foregoing, compared to existing technology, during the present embodiment cluster UE initiation group call business, its letter
Making interaction step less, therefore time delay is also few, thus meets the group service needs to time delay.
Further, when called service is carried out for UE, also include after above-mentioned steps S103:
Step S108, after UE receives beep-page message, in the group information after the renewal preserve this locality
Group mark identifies with the group in beep-page message and contrasts, it is judged that whether beep-page message is to seek this UE
Exhale；The most then enter step S109；Otherwise, flow process is terminated；
Step S 109, according to the configuration information in reservation system Resource Block, the cycle on FACH that obtains sends
Group call resource configuration message, set up corresponding channel resource, carry out group and exhale called voice service.
Above-mentioned steps S108 and step S109 are that UE group exhales called process, and the present embodiment is in order to contract as far as possible
Short time-delay, after UE receives the beep-page message of network, does not carry out RRC connection establishment process.Its physics
The acquisition mode of resource is that network is believed at the special FACH of cluster by reading the acquisition of cluster FACH channel
Periodicity broadcast physical channel configuration information on road, after UE reads this physical channel configuration information, thing
Reason channel configuration information is allocated to physical layer, enters state of listening, and obtains voice messaging.For rear start
UE, again may be by monitoring cluster special FACH channel, enters and listen state, and referred to herein as lag access
Group is exhaled.
Specifically, for the terminal of normal Standby, the called process of its cluster multi call is:
1, after cluster UE receives beep-page message, by the cell " Group identity " in beep-page message and
UE preserved all groups mark contrast, if having one identical, then be shown to be the paging to this UE,
UE then corresponding beep-page message；
2, UE reads cluster special FACH channel (configure and obtain from SIB30), obtains this FACH letter
The group call resource configuration message that cycle on road sends, therefrom gets business and configures with channel resource
Situation, and set up corresponding channel resource with this；
3, UE opens voice channel, receives downlink voice information, enters and listens state.In order to prevent voice
Information dropout phenomenon, above-mentioned steps 2 and step 3 parallel work-flow.
It addition, for the UE of the start that lags, start shooting the most resident after, it is to be understood that current the most
The group-calling service belonging to group exists, and therefore UE needs actively to remove readset group special FACH channel, because
Message on this channel is periodically to send, therefore necessarily can read the status information of affiliated group, as
Fruit with the presence of business, is then actively accessed and obtains voice messaging.
As the above analysis, the called subscriber of the present embodiment cluster UE after receiving paging, itself and network
Signalling exchange, only one of which receive paging process, UE pass through inter-process, can be automatically into listening
State, reception group exhales voice messaging.
It is resident that the present embodiment is possible not only to make UE successfully to carry out community, and when group-calling service, UE is without entering
Row RRC connection establishment, and obtain, according to the configuration information in reservation system Resource Block, the group that FACH sends
Exhale resource distribution message, set up corresponding channel resource, carry out group and exhale called voice service, thus shorten
The time delay of UE cluster multi call, and then improve Consumer's Experience effect.
