Description

Paging method and dispatch server

technical field

The present invention relates to the communication field, in particular, to a paging method and a scheduling server.

Background technique

At present, trunking mobile communication is a more flexible mobile communication system developed in the 1970s, and it is an advanced development stage of traditional dedicated radio dispatching network. The traditional dedicated radio dispatching system has poor overall planning, mixed models and standards, many small network stations, narrow coverage, severe noise interference, and waste of frequency resources. Therefore, a new radio scheduling technology - trunking mobile communication emerges at the historic moment. It is generally believed in domestic and foreign communication circles that trunking mobile communication in private radio communication is an advanced communication system that goes hand in hand with cellular mobile communication. In recent years, trunking mobile communication systems have been widely used.

The so-called trunking (Trunking), that is, using multiple wireless channels to serve a large number of users, is to apply the working mode of wired telephone trunk lines to the radio communication system, and to dynamically, automatically, quickly and optimally use limited channels Allocate to all users of the whole system, so as to utilize the frequency resource of the channel of the whole system to the greatest extent. It uses switching technology and computer technology to provide a strong grouping capability for all users of the system. It can be said that the trunking mobile communication system is a special user program-controlled exchange.

Trunking communication has gone through a simple intercom system (one-to-one intercom form) to a single base station small system (same-frequency simplex networking form, different-frequency single (dual) work networking form, single-channel one call form, with selective call form , multi-channel automatic dialing form), and then to the development process of large-capacity multi-area system (multi-channel user sharing form), and then experienced a leap from analog trunking to digital trunking. More reliable digital processing methods can be used in multiple access methods, speech coding, modulation and demodulation technology, synchronization technology, error detection and error correction, and diversity technology. In order to promote the large-scale application of the trunking system and further improve the frequency utilization rate, a new application trend has emerged in the application of the trunking communication system, which is to combine multiple trunking systems for unified use and management, so as to achieve the ability to share channels and Channels, shared coverage areas, communication services, and shared expenses. This approach gradually develops cluster applications from applications for individual professional users to applications for multiple group users. That is to say, cluster applications are moving towards shared network operation direction of development. This development will undoubtedly promote the development of group exercises in the direction of large-scale industrialization. Therefore, the development of trunking communication from a private network to a public network has promoted the development of existing public networks (for example, Global system for Mobile Communication (GSM for short), Code Division Multiple Access (CDMA for short)) Realize research on cluster technology.

Fig. 1 is the schematic diagram according to the composition of the trunking system of related technology, as shown in Fig. 1, the digital trunking system based on CDMA2000 system comprises: mobile terminal (MobileStation, hereinafter abbreviated as MS), base transceiver station (Base Transceiver Station, hereinafter Abbreviated as BTS), base station controller (Base Station Controller, hereinafter abbreviated as BSC), Push To Talk (Push To Talk, abbreviated as PTT) dispatch client (PTTDispatch Client, hereinafter abbreviated as PDC), PTT dispatch server (PTT DispatchServer, hereinafter abbreviated as PDS) (hereinafter abbreviated as dispatch server), PTT home register (PTT Home Register, hereinafter abbreviated as PHR) (hereinafter abbreviated as home register), dispatching server (Dispatching Agent Server, hereinafter abbreviated as DAS ), and Dispatching Agent Client (hereinafter abbreviated as DAC).

The digital trunking system divides the call into single call and group call. The single call is the half-duplex communication mode between one user and another user. The related technology introduces how to use the trunking system to realize the single call function by using the CDMA system, and It improves the low utilization of frequency resources and solves the defects such as the inability to smoothly transition to the third-generation communication. Group call is a one-to-many half-duplex call mode, in which one user is allowed to speak and other users are listening, so it is necessary to establish corresponding resources for each user.

According to different ways of establishing resources, in the existing trunking system, there are mainly two ways of paging user terminals, one is enhanced paging, and the other is traditional paging. Among them, the enhanced paging message carries the terminal identifier of a specific user. When the user terminal responds to the enhanced paging and accesses the call, it will send a paging response message to the system, indicating that it has accessed the call, while the traditional paging The message carries the group ID of a specific group. When the terminal of the user in the group responds to the traditional paging and accesses the call, it will not feed back any response message to the system, and the terminal will answer the paging according to its own group ID. Build resources.

Taking the cell as the unit, we divide the Location Area Code (LAC for short) and the Dispatch Location Area (DLA for short) according to actual needs, and multiple DLAs can form a Dispatch Service Area (Dispatch Service Area for short). DSA), where the LAC is divided according to the actual terrain and location, and the DLA is divided according to the scheduling needs. We will form a set of DLAs that are often used for scheduling, that is, DSA.

Traditional paging can be performed according to LAC or DLA. The base station will send an indication message without resources to the terminal after receiving the paging according to LAC. Paging allocates resources. After the base station receives the paging according to the DLA paging, it directly carries the sending resource, and the terminal directly establishes the resource after responding.

Fig. 2 is a flow chart according to the paging mode of LAC without resources according to the related art. As shown in Fig. 2 , the traditional group paging process according to LAC paging includes the following steps 201 to 210:

Step 201: The terminal initiates a call, and the call request is sent to the PDS through the BSC.

Step 202: After receiving the call request, the PDS requests authentication from the PHR, and applies for the user's basic location information and group ID.

Step 203: The PHR returns the basic user information and all LAC information corresponding to the BSC to the PDS, and judges that the group is a traditional group after passing the authentication.

Step 204: The PDS performs traditional paging to the base station according to the LAC to all corresponding cells under the BSC.

Step 205: A service channel is established between the PDS and the wireless side.

Step 206: Since the BSC has received the paging from the LAC, after answering the paging from the PDS, the BSC performs paging without resource to each cell where it is located.

Step 207: The terminal responds to the BSC after receiving the paging.

Step 208: The BSC receives a response from the terminal indicating that there is a terminal under the LAC, so it resends the paging with resources, and establishes wireless resources after the terminal responds.

Step 209: After the radio resources are established, the BSC responds to the paging of the PDS.

Step 210: After the resource is established and the PDS grants the speaking right, the user starts to speak.

Fig. 3 is a flow chart of a paging method with resources according to DLA according to the related art. As shown in Fig. 3, the traditional group paging flow according to DLA paging includes steps 301 to 308 of admission:

Step 301 to step 302: the same as step 201 to step 202 of the above-mentioned traditional group call according to LAC paging, and will not be repeated here.

Step 303: The PHR returns the basic information of the user and all DLA information under the BSC to the PDS, and judges that the group is a traditional group after passing the authentication.

Step 304: The PDS performs conventional paging to the base station according to the DLA.

Step 305: the PDS and the wireless side establish a traffic channel.

Step 306: Since the BSC has received the DLA paging, after responding to the PDS paging, the BSC sends a paging with resource to the cell where each DLA is located, and the terminal directly establishes the radio side resource after answering.

Step 307: After the wireless resources are established, the BSC responds to the paging of the PDS.

Step 308: After the resources are established and the PDS grants the speaking right, the user starts to speak.

Fig. 4 is a schematic diagram of the network structure according to the user cell distribution of the related art. As shown in Fig. 4, MS_1, MS_2, and MS_3 are a group respectively under cells Cell_1, Cell_2, and Cell_3, Cell_1 and Cell_3 form DLA_1, and Cell_4 forms DLA_2, Cell_1 forms LAC_1, Cell_2 and Cell_4 form LAC_2, and Cell_3 forms LAC_3.

Case 1: If the PDS pages in DLA_1 and DLA_2 according to DLA, resources are quickly established in Cell_1, Cell_3, and Cell_4, but there are no users in Cell_4, which causes resource waste in the cell.

Case 2: If paging is sent in LAC_1, LAC_2, and LAC_3 according to LAC, paging without resources is performed in each cell, and the user's Cell_1, Cell_2, and Cell_3 cells have terminals answering and then the base station sends paging with resources. Phew, this situation can ensure that base station resources will not be wasted, but in this case the access time is longer and the access speed is slower.

In view of the characteristics of the traditional group call of CDMA digital trunking, in order to use the least resources in the shortest time to make all users access to the group call, it introduces different types of paging. The user's paging method.

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

The traditional type and the enhanced fusion method described in the present invention are based on the CDMAZ000 digital trunking system, and its network schematic diagram is as shown in Figure 1, and each component is described as follows:

Trunk terminal (MS): A terminal device capable of storing user information, group information, scheduling area judgment, response, group call paging and other trunking services.

method embodiment

According to an embodiment of the present invention, a paging method is provided. FIG. 5 is a flowchart of a paging method according to an embodiment of the present invention. As shown in FIG. 5, the method includes the following steps 502 to 506:

Step 502, the user (terminal) initiates a call, and the PDS receives a call request from the terminal, wherein the call request carries the basic information of the terminal and all location information of the place where the call originates. The location information includes: location information of the LAC and location information of the DLA location information.

Thereafter, the PDS records the location information in the local database, forms a DLA table (ie, DLA_List) of all the DLAs to which the terminal that initiates the call request belongs, and queries the LACs included under the corresponding BSC, and forms a LAC set according to the query results.

Step 504, the PDS authenticates the PHR according to the call request, and sends the recorded caller location information according to the DLA to the BSC according to the authentication result, and the DLA is based on the scheduling area so that the terminals in the group in the dispatching area can access the call at the first time. Wherein, the DLA table is carried in the first paging message, so that the BSC sends the paging with resources to the corresponding cell according to the DLA table.

Specifically, the PDS authenticating the PHR according to the call request includes: the PDS authenticates the PHR after receiving the calling message, and the PHR judges the legitimacy of the user. PHR receives the authentication request from PDS, judges the legitimacy of the user indicated in the authentication request, and searches the basic information and group type of the called party at the same time; Sent to PDS as the authentication result.

Thereafter, the BSC receives the first paging message from the PDS according to the DLA; the BSC/PDC and the PDS establish a traffic channel; the BSC sends paging with resources to the cells belonging to the DLA according to the DLA table carried in the first paging message, So that the terminals in the group under these cells are all connected to the call.

Step 506, after the terminal in the group to which the DLA belongs accesses the call, the PDS sends a second paging message to the BSC according to the LAC, so that the terminal in the group not in the DLA accesses the call.

Thereafter, the BSC receives the second paging message per LAC from the PDS, and sends paging without resources to all cells included in the LAC set, so that terminals in the group under all cells can access the call. The paging of the LAC can basically cover all the cells involved in the call under the BSC, and the users in the group not in the DLA can accept the paging. Then, BSC receives paging response messages from terminals in all cells, and sends paging messages with resources to terminals; BSC receives response messages from terminals, and establishes radio resources with terminals, so that terminals can access calls. That is to say, for a cell with users, if the user answers the paging, resources are established in the cell, and the user joins the call. A cell with no users If no users answer the paging, no resources will be established in the cell.

It should be noted that in the existing paging mode, the PDS will not send traditional paging after the first paging, and the paging added in the embodiment of the present invention is for the first paging Replenish. The paging carries the LAC set recorded in step 502 . If the LAC is shared by multiple BSCs, the paging message will also be sent to other BSCs, but the paging message only carries the identifier of the shared LAC. This paging does not carry resources. In order to ensure the access of all users in a wider range, this paging can be configured with retransmission times and retransmission intervals according to actual conditions.

Through this embodiment, a supplementary paging mechanism is provided. The PDS only needs to be slightly optimized in the process, and the BSC and the PDC do not need to make any changes, and the user can be efficiently and quickly connected to the call, thereby solving the problem of wireless side resources and Inconsistency between access speeds.

The specific implementation of the solution will be introduced below in combination with the flow of FIG. 6 , and the example provided in FIG. 4 will be used for illustration during the flow of FIG. 6 .

In Figure 4, DLA_1, DLA_2, LAC_1, LAC_2, and LAC_3 are configured under the BSC, and MS_1, MS_2, and MS_3 belong to a group. FIG. 6 is a detailed flowchart of a paging method for different user paging modes according to an embodiment of the present invention. As shown in FIG. 6 , it includes the following steps 601 to 612:

In step 601, the terminal initiates a call, carrying the DLA and LAC information of the call. In Fig. 4, MS1 initiates a call, and brings the IDs of DLA_1 and LAC_1 to the PDS, and the PDS records it in its own database.

In step 602, after receiving the call request, the PDS requests authentication from the PHR, and applies for the user's basic location information and group ID.

In step 603, the PHR returns the basic user information and group identification information to the PDS, and judges that the group is a traditional group after passing the authentication. After the PHR determines that MS_1, MS_2, and MS_3 are legitimate users, it will pass the identification to the PDS.

In step 604, the PDS sends a paging to the DLA where the calling party is located. In FIG. 4, the PDS sends a broadcast paging, and the paging message carries the identifier of DLA_1.

In step 605, a service channel is established between the PDS and the BSC/PDC.

Step 606, BSC receives PDS paging, BSC judges that the paging is sent according to DLA, and then sends paging with resources to each cell corresponding to DLA. Send paging with resources, and MS_1 and MS_3 will establish resources after responding.

In step 607, the BSC/PDC responds to the paging sent by the PDS.

In step 608, the PDS sends a paging message to the BSC according to the LAC set under the BSC in the network configuration and carries all the LAC identifiers in the LAC set.

Step 609, when the BSC receives the paging of the PDS, the BSC judges that the paging is sent according to the LAC, that is, sends the paging without resources to the corresponding cells in the LAC set. In FIG. 4 , the BSC sends paging to Cell_1 , Cell_2 , Cell_3 , and Cell_4 to which LAC_1 , LAC_2 , and LAC_3 belong.

In step 610, the terminal responds to the BSC after receiving the paging, and MS_2 returns a response message after receiving the paging in the cell Cell_2.

In step 611, the cell that has responded to the response message from the BSC sends a paging setup resource with resource to connect the terminal to the call, and the cell that does not reply to the response message does not send a paging with resource. In Figure 4, the base station resends the paging with resources to MS_2 and establishes the MS_2 access call with resources. Although the paging without resources is received in Cell_4 but no user in the cell responds, the base station does not send paging to it in this step. call.

Step 612, the user can speak normally.

Through this embodiment, the situation in Figure 4 can be successfully resolved. This embodiment rationally applies the characteristics of paging by LAC and paging by DLA, and combines the cell distribution of users in actual use, without changing the base station paging Under the premise of the method, the contradiction between resources and access speed is solved to the greatest extent in an optimal way, which satisfies the needs of customers and realizes paging all users to access the group in the shortest time with the least resources. call.
