Definitions
- the present invention relates to a technique for transmitting a short message in a cluster system, and more particularly to a method for a user outside the cluster to send a short message to a user in the cluster group.
- cluster wireless communication systems have emerged, referred to as cluster systems.
- the cluster system is a more economical and flexible command and dispatch communication system developed in recent years. It is widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, water conservancy and military units to meet various units. The need for internal communication.
- each cluster group includes a group identifier (ID) and a group call area, where the group call area is defined as a group of cells.
- ID group identifier
- group call area is defined as a group of cells.
- HLR Home Location Register
- SIM Subscriber Identity Module
- FIG. 1 is a schematic diagram of the core network structure of the cluster system.
- the HLR stores user information, including the user's International Mobile Subscriber Identity (IMSI), the cluster group ID list to which it belongs, and the gateway mobile switch.
- IMSI International Mobile Subscriber Identity
- GMSC Gateway Mobile Switching Center
- MSC Anchor Mobile Switch
- VGCS Voice Group Call Service
- VLR Visitor Location Register
- IMSI the ID list of the cluster group to which the user belongs, when the user roams, the information is copied from the HLR; the group call register (GCR, Group The group ID and the group call area are included in the group, and the group call area and the group ID are collectively referred to as a group call reference, and the GCR connected to the Anchor MSC includes the dispatcher associated with the group call reference.
- the list, the relay MSC list, the cell list directly controlled by the Anchor MSC, and the cluster group call with the group call reference have established information, and the GCR connected to the relay MSC includes the Anchor MSC associated with the group call reference. Address, list of cells controlled by the relay MSC.
- the Anchor MSC Upon receiving the group call initiation request, the Anchor MSC queries the connected GCR for the group attribute, thereby obtaining a dispatcher list, a relay MSC list, and a cell list under the control of the MSC and a cluster group call with a group call reference. Whether information has been established.
- the Anchor MSC establishes a voice group call (VGCS Ca ll ), that is, an Anchor MSC call dispatcher, calls the relay MSC, and each cluster under the control of the relay MSC
- VGCS Ca ll voice group call
- the cells in the group establish a group call channel, and notify the users in the cluster group that the group call is initiated by the notification channel (NCH, Not if ica t ion Channel) of each cell, and indicate the group call channel thereof so that the users in the cluster group can listen;
- the Anchor MSC calls the dispatcher, occupies the group call channel, directly calls the relay MSC, and the cells in each cluster group under the control of the relay MSC notify the users in the cluster group that the group call is initiated, and indicates the group call.
- the channel is monitored by users in the cluster group.
- the cluster users in the cluster group can send short messages to be sent to other cluster users in the cluster group by preempting the group call channel. If not established, the cluster user in the cluster group can initiate the group call establishment process. After the group call is established, the short message to be sent is sent to other users in the cluster group through the established uplink group call channel.
- 2 is a flow chart of a process for a user outside the cluster group to send a short message to a user in the cluster group, and the specific steps are as follows:
- Step 200 Send a short message to be sent by the user outside the cluster group to the network side of the cluster system.
- Short message service center the short message carries a group call reference of the destination cluster group;
- Step 201 The short message service center saves the short message, and the network side of the cluster system determines whether the cluster group having the group call reference carried by the short message has established a group call, and if yes, step 202 is performed; otherwise, step 203 is performed;
- Step 202 The cluster system network side uses the group call channel of the cluster group, and sends a short message stored in the short message service center to the user in the cluster group through the downlink group call channel of all the cells in the cluster group call area. ;
- Step 203 The network side of the cluster system waits for the cluster group to establish a group call, and the group call channel of the cluster group is used only after the cluster group establishes the group call, and the downlink group call of all the cells in the group call group area of the cluster group is used.
- the channel sends a short message stored in the short message service center to the user in the cluster group.
- This scheme for sending short messages has the following disadvantages: After a short message is sent by a user outside the cluster group, it is impossible to determine when the short message can be sent to the users in the cluster group. If the cluster group of the short message destination does not establish a group call, the short message transmission delay will be delayed, and the delay time may reach several hours or days, which is related to when the cluster group establishes a group call. Further, due to the delay of sending short messages, short messages are stored in the short message service center for a long time, and the storage space of the short message service center is wasted.
- the main purpose of the present invention is to provide a method for sending a short message to a user in a cluster group by a user outside the cluster group, and the method can enable the user outside the cluster group to send the short message to the cluster group in time.
- the user thereby preventing the transmission delay of the short message, saves the storage space of the short message service center.
- the specific technical solution of the present invention is implemented as follows:
- the method for sending a short message to a user in a cluster group by the user outside the cluster group provided by the present invention includes ' ⁇
- the network side of the cluster system receives the short message sent by the user outside the cluster group, and determines whether the group call has been established. If yes, the network side of the cluster system passes the existing group call of the cell in the cluster group call area. The channel sends a short message to the user in the cluster group; otherwise, step b is performed; b. The cluster system network side establishes the cluster group group call, and sends a short message by using the group call channel established by the cell in the group group call area of the cluster group. Give users in the cluster group.
- step b the cluster group call is established as a voice group call VGCS Ca ll or a voice broadcast call VBS Ca ll 0
- Step a the short message carries a cluster group call reference
- the process of establishing the cluster group call in step b is as follows:
- the network side of the cluster system establishes a group call channel in the cell of the cluster group call area, and carries the bearer on the notification channel of the cell in the group call area of the cluster group.
- the group calls the channel establishment information and the notification message of the cluster group call reference.
- the established group call channel is an independent control channel SDCCH or SACCH.
- the method further includes: releasing the group call of the cluster group on the network side of the cluster system.
- the short message further carries a short message identifier
- the method further includes the step of the user in the cluster group receiving the short message: the user in the cluster group determines whether the short message identifier carried by the short message to be received is received by the user in the cluster group. The same short message, if yes, does not receive the short message, otherwise, the short message is received.
- the cluster group network side stores the users outside the cluster group that are allowed to send short messages to users in the cluster group. Before determining whether the cluster group has established a group call as described in step a, the method further includes Includes:
- the cluster system network side determines whether the user outside the cluster group that sends the short message is allowed to send the short message to the cluster group according to the stored user outside the cluster group that allows the short message to be sent to the users in the cluster group. If yes, go to step a.
- the cluster group user that allows the short message to be sent to the user in the cluster group is stored in the group call register on the network side of the cluster system, and the stored cluster group user that allows the short message to be sent to the user in the cluster group is stored. Write to write or modify when opening an account.
- the method further includes:
- the network side of the cluster system determines whether the user outside the cluster group that sends the short message is allowed to establish the cluster group call according to the stored user outside the cluster group that is allowed to initiate the cluster group call. If yes, go to step b. Otherwise, , End.
- the cluster group out-of-group user that is allowed to initiate the cluster group call is stored in the group call register on the cluster system network side, and the stored cluster group user allowed to send the short message to the user in the cluster group is Write when opening an account or write when changing.
- the present invention does not, as described in the prior art, if the short message destination cluster group does not establish a group call, wait for the cluster group to establish a group call, and then send a short message after the cluster group establishes the group call, resulting in The delay of the short message.
- the present invention enables the users outside the cluster group to timely send short messages to users in the cluster group, thereby preventing the transmission delay of the short message and saving the storage space of the short message service center.
- the group call mode of the cluster system actively establishes the group call mode of the cluster group to transmit short messages by using a Stand-alone Dedicated Control Channel (SDCCH), thereby saving the time for establishing a group call.
- the method provided by the present invention further sets the permission for sending the short message and the permission for initiating the cluster group call to the users outside the cluster group, so as to ensure that only the users outside the cluster group having the authority can send the short message.
- the cluster group call is established through the network side of the cluster system when the short message is sent, the security of sending the short message in the cluster system is improved.
- Figure 1 shows the core network structure of the cluster system.
- Figure 2 is a flow diagram of a short message sent by users outside the cluster group to users in the cluster group.
- FIG. 3 is a flowchart of sending a short message to a user in a cluster group by a user outside the cluster group according to the present invention. Mode for carrying out the invention
- the network side of the cluster system actively establishes the group call of the cluster group. Then, the short message is sent to the user in the cluster group through the established cluster group call.
- FIG. 3 is a flowchart of sending a short message to a user in a cluster group by a user outside the cluster group according to the present invention, and the specific steps are as follows:
- Step 300 The short message sent by the user outside the cluster group is sent to the short message service center on the network side of the cluster system, where the short message carries the group call reference of the destination cluster group;
- Step 301 The short message service center on the network side of the cluster system saves the short message, and the network side of the cluster system determines the Anchor MSG according to the group call reference carried by the short message;
- Step 302 The Anchor MSC queries the GCR according to the group call reference to have the group call reference. Cluster group call status;
- Step 303 The GCR determines, according to the pre-stored information that the group group call with the group call reference has been established, whether the group group call with the group call reference has been established. If yes, go to step 304; otherwise, perform steps. 305;
- Step 304 The GCR feeds back to the Anchor MSC that the cluster group call with the group call reference has been established, and the Anchor MSC uses the group call channel in all the cells in the cluster group call area according to the prior art, and is saved in a short
- the short message of the message center is sent to the user in the cluster group having the group call reference through the downlink group call channel, and step 308 is performed;
- the downlink group call channel may be a slow associated control channel (SACCH, S low As sociated control channel), and needs to be accompanied by a traffic channel (TCH, Traffic Channel);
- SACCH slow associated control channel
- TCH Traffic Channel
- Step 305 The GCR feeds back to the Anchor MSC that the cluster group call with the group call reference is not established. After receiving the message, the Anchor MSC establishes a group call in the cluster group with the group call reference, that is, the group is established. Call channel
- the temporary call can also be a voice broadcast call (VBS CALL, Vo ice Broadcas).
- VBS CALL Voice Broadcas
- t Service Cal l the process is the same as the VBS CALL process in the prior art;
- the group call channel established here may be a SACCH or a Stand-A lone Dedicated Control Channel (SDCCH), and does not need to be accompanied by a TCH, because the established group call channel does not transmit voice services;
- SDCCH Stand-A lone Dedicated Control Channel
- Step 306 The Anchor MSC sends a notification message to the NCH of all the cells in the cluster group call area, where the message includes a group call reference and a group call channel configuration message of the cluster group.
- Step 307 The Anchor MSC sends a short message on the downlink group call channel of the group call channel established in all the cells in the cluster group call area.
- the downlink group call channel is an SDCCH channel; Step 308: After the short message is sent by the Anchor MSC, the short message center is notified, and the short message center deletes the short message and releases the storage space.
- the Anchor MSC of step 307 can send a short message multiple times, and the short message also carries a short message identifier, which is received by the user in the cluster group.
- the short message is received, it is determined according to the short message identifier whether the short message has been received, thereby preventing the user in the cluster group from repeatedly receiving the same short message.
- the group call of the cluster group is released.
- the user who initiates the group call releases the currently established group call
- the second type the dispatcher authorized in the cluster ⁇ releases the currently established group call
- the third type the cluster system network side, that is, the cluster system's Anchor MSC monitors the setting The currently established group call in the time value is inactive, and the currently established group call is released.
- the present invention can not only adopt the existing group call dry-distribution mode, but also can initiate the group call process of releasing the cluster group by the cluster system network side of the cluster system that sends the short message, that is, the cluster MSC.
- the release process and the cluster system network side monitor that the group call process is the same when the group call currently established in the set time value is in the inactive state, that is, directly release all established group call channels in the cluster group call zone and Notification channel.
- users outside the cluster group can send short messages to users in the cluster group. Users outside the cluster group can send short messages to users in the cluster group.
- a cluster group user that allows short messages to be sent to users in the cluster group can be stored.
- the network side of the cluster system determines the cluster group based on the stored information. Whether the user can send a short message to the users in the cluster group, and if so, perform the subsequent steps of step 301 in FIG. 3; otherwise, the process ends.
- the present invention can store cluster out-of-group users that allow short messages to be sent to users in the cluster group.
- GCR on the network side of the cluster system
- users outside the cluster group that are allowed to send short messages to users in the cluster group are stored when the account is opened, or cluster groups that have been stored to allow short messages to be sent to users in the cluster group.
- External users delete and modify.
- the invention can also set the permission of the user outside the cluster group to initiate the cluster group call, and the user outside the cluster group can establish the cluster group call through the network side of the cluster system.
- the users outside the cluster group that are allowed to initiate the cluster group call can be stored, so that when the user outside the cluster group sends a short message, the network side of the cluster system determines, according to the stored information, the user outside the cluster group. Whether to establish a group call through the cluster system, if yes, perform step 305 and subsequent steps in FIG. 3; otherwise, end the process.
- the invention can store the users outside the cluster group group that are allowed to initiate the cluster group call in the GCR of the cluster system network side, and allow the users outside the cluster group group that initiates the cluster group group call to store when opening an account, or It has been stored as a user outside the cluster group that allows the cluster group call to be initiated to be deleted and modified.
