Description

Cluster public land mobile network information transmitting and receiving method and device

Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for transmitting and receiving cluster public land mobile network (PLMN) information in a broadband wireless communication system.

Background technique

With the rapid development of mobile communication technology, as an important branch of mobile communication, cluster communication technology has also made great progress.

Providing professional clustering functions in LTE (Long Term Evolution) broadband wireless communication systems, so that cluster services can largely apply existing hardware resources in broadband wireless communication systems, reducing operating costs, and simultaneously clustering services. The scope of development has also been expanded to be fully applicable to high-speed data, video and build on this basis, including mobile office, multimedia cluster scheduling, video surveillance, and urban emergency linkage.

As shown in Figure 1, an LTE broadband wireless communication system that provides professional clustering functions (hereinafter referred to as

The network architecture of the LTE trunking system is still composed of a core network, an eNB (Evolved Node B), and a UE (User Equipment). The core network includes the public network core network EPC (Evolved Packet Core network). , Evolved Packet Core Network) and Cluster Core Network DSS (Dispatching Server Subsystem). The public network core network EPC belongs to the LTE network. It is an LTE core network device that conforms to the standard protocol. When the LTE service needs to be provided for the terminal UE, the EPC-related device needs to be deployed. The cluster core network DSS belongs to the cluster network. When the LTE cluster system provides the professional cluster function, the DSS related equipment needs to be deployed; the eNB is responsible for the access network part, also called E-UTRAN (Evolved UTRAN, evolved UTRAN), which is shared by the LTE network and the cluster network; the eNB and the public network The core network EPCs are connected through the S1 interface, and the eNB and the cluster core network DSS are connected through the T1 interface.

The Public Lands Mobile Network (PLMN) area is a geographical area in which a particular carrier provides mobile communication services to users. As shown in Figure 1, the PLMN to which the public network core network belongs is PLMN A, and the PLMN to which the cluster core network belongs is PLMN B. The PLMN A and PLMN B here may be the same or different, specifically by the actual network operator. to make sure. In the LTE system, the PLMN information (PLMN-IdentityList) is delivered in the system information SIB1 (System Information Block Type 1) of the cell.

Taking the LTE cluster system network shown in FIG. 1 as an example, the PLMN-IdentityList obtained by the UE from the received cell system information SIB1 includes PLMN A of the LTE network and PLMN B of the cluster network. However, when the LTE trunking system network does not need to provide the normal LTE service service for the terminal UE, the public network core network EPC is not deployed. At this time, there is no PLMN A belonging to the LTE network in FIG. 1 in the cell system information SIB1. The PLMN-IdentityList only has the PLMN B of the cluster network; and when the S1 interface fails (that is, the link communication between the eNB and the public network core network EPC is abnormal), the PLMN A belonging to the LTE network will not be in the cell at this time. The PLMN-IdentityList in the system information SIB1 is delivered, and the PLMN-IdentityList in the SIB1 is only the PLMN B of the cluster network; when the LTE cluster system network does not provide the cluster function, or the T1 interface in the LTE cluster system network is faulty (ie, the eNB and the cluster core) When the link communication between the network DSSs is abnormal, the cluster-related content is not sent in the cell system information, as in the normal LTE network. Of course, the PLMN-IdentityList in the cell system information SIB1 does not include the cluster. PLMN B of the network.

It can be seen that the UE obtains the PLMN-IdentityList from the received cell system information SIB1, but the UE cannot determine whether the PLMN-Identity in the PLMN-IdentityList belongs to the LTE network or the cluster network, and thus cannot be confirmed to belong to the LTE network. Whether the PLMN exists in the list, that is, it cannot be confirmed whether the LTE broadband wireless communication system can provide the normal LTE service service for the UE, so the UE (including the cluster UE and the normal LTE UE) also initiates registration with the public network core network EPC. When the LTE service is used, the UE initiates these services and fails. It directly disrupts the normal operation of the system and affects the KPI index of the system. In addition, when the PLMN-IdentityList contains multiple PLMN-Identities, the UE cannot determine the PLMN-IdentityList. Which PLMN-Identity belongs to the LTE network and which belongs to the cluster network, so it is impossible to confirm which of the PLMN-IdentityLists should be selected by the selected PLMN-Identity in the message such as RRCConnectionSetupComplete.

Preferred embodiment of the invention

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

Example 1

The Applicant's inventor proposes to extend the LTE cluster system parameters and increase the cluster PLMN parameter list to distinguish it from the PLMN belonging to the LTE network. The PLMN to which the EPC of the public network core network belongs, that is, the PLMN of the LTE network (hereinafter referred to as LTE PLMN), is still in accordance with the LTE standard protocol specification.

The PLMN belongs to the PLMN-IdentityList in the first parameter of the cell system information (that is, the existing parameter of the SIB1); and the PLMN to which the cluster core network DSS belongs, that is, the PLMN of the cluster network (hereinafter referred to as the cluster PLMN), The LTE cluster system parameters are delivered in the newly added cluster PLMN parameter list.

Based on the above idea, the embodiment provides a method for transmitting a PLMN information. The method assumes that the LTE cluster system provides both the common LTE service and the professional cluster function, that is, the public network core network EPC and the cluster core network DS S are deployed at the same time. In principle, both the LTE PLMN and the clustered PLMN eNB need to be delivered to the UE in the cell system information, but the LTE PLMN and the cluster PLMN information are filled in different locations in the cell system information to indicate the difference. Specifically, the sending method includes the following operations:

The base station acquires LTE PLMN parameter list information and cluster PLMN parameter list information that need to be broadcast to the UE;

The base station fills in the LTE PLMN parameter list information that needs to be broadcast according to the LTE protocol. The first parameter written to the cell system information (that is, the existing parameter of the SIB1) is sent to the UE;

When the link communication between the base station and the DSS is normal, the base station fills in the second parameter of the cell system information to the UE, where the second parameter is the existing SIB. Extended parameters or new SIB parameters.

It should be noted that the cluster PLMN parameter list sent by the base station includes one or more clusters.

PLMN logo.

According to the specific application scenario, the above method is normal on the S1 interface (that is, the link communication between the eNB and the EPC of the public network core is normal), and the T1 interface is also normal (that is, the link communication between the eNB and the cluster core network DSS is normal. LTE PLMN and the cluster PLMN need to be delivered in the cell system information;

When the S1 interface is faulty (that is, the link communication between the eNB and the public network core network EPC is abnormal), but the T1 interface is normal (that is, the link communication between the eNB and the cluster core network DSS is normal), only the cell system information is included. The cluster PLMN is delivered, and the LTE PLMN is not sent.

When the S1 interface is normal (that is, the link communication between the eNB and the public network core network EPC is normal), but the T1 interface is abnormal (that is, the link communication between the eNB and the cluster core network DSS is abnormal), only the cell system information is included. The LTE PLMN is delivered, and the cluster PLMN is not sent;

When the S1 interface is abnormal (that is, the link communication between the eNB and the public network core network EPC is abnormal), and the T1 interface is abnormal (that is, the link communication between the eNB and the cluster core network DSS is abnormal), the cell is not established at this time. , will not send cell system information.

The LTE cluster system only provides the professional cluster function and does not provide the common LTE service. In the case that only the cluster core network DSS is deployed and the public network core network EPC is not deployed, the eNB sends the cluster to the UE only in the cell system information. The PLMN does not issue the LTE PLMN.

When the T1 interface is normal (that is, the link communication between the eNB and the cluster core network DSS is normal), the cluster PLMN is sent in the cell system information; when the T1 interface is abnormal (that is, the link communication between the eNB and the cluster core network DSS) In case of abnormality, the cell will not be established at this time, and the cell system information will not be sent.

It is assumed that the LTE cluster system only provides the normal LTE service and does not provide the professional cluster function. That is, only the public network core network EPC is deployed and the cluster core network DSS is not deployed. In principle, the eNB sends only the LTE to the UE in the cell system information. The PLMN does not issue the cluster PLMN.

When the S1 interface is normal (that is, the link communication between the eNB and the public network core network EPC is normal), Sending an LTE PLMN in the cell system information;

When the S1 interface is abnormal (that is, the link communication between the eNB and the EPC of the public network is abnormal), the cell will not be established and the cell system information will not be sent. After the LTE PLMN is sent in the above manner, the normal UE (which does not support the cluster function) receives the cell system information, and obtains the LTE PLMN parameter list information from the first parameter of the cell system information (that is, the existing parameters of the SIB1), if the LTE PLMN is in the LTE PLMN. If the appropriate LTE PLMN is available in the parameter list information, the registration is initiated to the public network core network EPC. After the registration is successful, the normal UE can initiate the normal LTE service; the selected PLMN-Identity in the RRCConnectionSetupComplete message should select LTE. Fill in the PLMN parameter list.

The cluster UE (supporting the cluster function) receives the cell system information, and first obtains the LTE PLMN parameter list information from the first parameter of the cell system information (that is, the existing parameter of the SIB1), if there is a suitable LTE in the LTE PLMN parameter list information. When the PLMN is available for selection, it initiates registration with the public network core network EPC; only after the registration is successful, the ordinary LTE service can be initiated; when the ordinary LTE service (including registration) is performed, the selected PLMN in the RRCConnectionSetupComplete message -Identity should be selected in the LTE PLMN parameter list. Then, the cluster system parameters are obtained from the cell system information, and if the cluster system parameters exist, the cluster PLMN parameter list information is obtained therefrom; if a suitable cluster PLMN is available for selection in the cluster PLMN parameter list information, the cluster core network DSS is initiated. Registration; After the registration is successful, the cluster service can be initiated; when the cluster service (including registration) is performed, the selectedPLMN-Identity in the RRCConnectionSetupComplete and other messages should be selected in the cluster PLMN list.

The implementation process of the above sending method will be described in detail below in conjunction with the application scenario.

Based on the above method, the LTE cluster system parameters are extended, and the cluster PLMN parameter list is added, which is referred to herein as TPLMN-IdentityList, to distinguish the PLMN-IdentityList in the existing parameters of SIB1.

The current system information block type (SIB) of the LTE R9 protocol version is SIB 1, SIB2, SIB3, ..., SIB13. In the LTE cluster system, the normal LTE service is not affected. For use, the cluster parameters are generally selected in the extended parameters of the SIB (herein referred to as SIB1-SIB13 specified in the LTE R9 protocol version), or placed in a new system information block type (unlike the SIB1 specified in the LTE R9 protocol version). -SIB13, can root According to the actual situation, at least one system information block is arbitrarily expanded, and the newly added cluster PLMN parameter list also belongs to the cluster parameter category. It is assumed here that the newly added cluster PLMN parameter list is placed in the second parameter (that is, in the extended parameter of SIB1-SIB13, or in the parameter of the newly added SIB), and the newly added cluster PLMN parameter list content in the second parameter The details are as follows:

Table 1

Take the LTE cluster system network architecture shown in Figure 1 as an example. In the figure, the LTE PLMN (the PLMN to which the public network core network belongs) is PLMN A, and the cluster PLMN (the PLMN to which the cluster core network belongs) is the PLMN B _0.

In the LTE cluster system, the network side eNB broadcasts to the UE (including the normal LTE UE and the cluster UE)

The process of the LTE PLMN and the cluster PLMN parameter list is as shown in FIG. 2, and includes the following steps S201 to 203:

Step S201: The eNB acquires LTE PLMN parameter list information that needs to be broadcast to the UE. If the public network core network EPC in Figure 1 is deployed and the S1 interface is normal (that is, the link communication between the eNB and the public network core network EPC is normal), the eNB fills in the PLMN A of the LTE network to the cell system information. In the PLMN-IdentityList of a parameter (the existing parameters of SIB1) (Note: this example only has PLMN A, the actual situation may exist multiple PLMNs); otherwise, if the public network core network EPC in Figure 1 is not deployed or deployed If the S1 interface is abnormal, the PLMN of the LTE network does not exist for the eNB. In this case, the PLMN identity is not filled in the PLMN-IdentityList of the SIB1, but the LTE protocol specifies that the PLMN identity information in the PLMN-IdentityList is 1-6. Therefore, in this case, fill in a PLMN identifier of all 0s in the PLMN-IdentityList.

Step S202: The eNB acquires cluster PLMN parameter list information that needs to be broadcast to the UE. If the cluster core network DSS in Figure 1 is deployed and the T1 interface is normal (that is, the link communication between the eNB and the cluster core network DSS is normal), the eNB fills in the PLMN B of the cluster network to the second parameter of the cell system information. In the TPLMN-IdentityList, where the second parameter is the existing SIB Extended parameters or new SIB parameters (Note: This example only has PLMN B. Actually, there may be multiple PLMNs); otherwise, if the cluster core network DSS in Figure 1 is not deployed or deployed, but the T1 interface is abnormal, Then, the PLMN of the cluster network does not exist for the eNB. At this time, the LTE cluster system parameters are not filled in. Of course, the cluster PLMN parameter list is not required to be filled out.

Step S203: The eNB broadcasts cell system information to the UE. In particular, when neither the LTE PLMN parameter list nor the cluster PLMN parameter list information exists (ie, the PLMN-IdentityList of the SIB1 includes only one PLMN identifier that is all 0s, and the cluster system parameter does not exist), the cell is not established at this time. The eNB does not broadcast cell system information to the UE.

Based on the above transmission process, the user receiving process is as follows:

First, the process of acquiring and processing an LTE PLMN by a normal UE on the user side is introduced. As shown in FIG. 3, steps S301 to 303 are included:

Step S301: The normal UE receives the cell system information from the eNB.

Step S302: The normal UE processes the acquired cell system information.

Step S303, in particular, the normal UE acquires the LTE PLMN parameter list PLMN-IdentityList from the existing parameters of the cell system information SIB1; if there is a suitable LTE PLMN available for selection in the LTE PLMN parameter list information, the public network is connected to the public network. The EPC initiates registration; after the registration is successful, the ordinary UE can initiate ordinary LTE services.

In this example, when the EPC of the public network core network in FIG. 1 is deployed and the S1 interface is normal, the normal UE can obtain the PLMN A from the cell system information, select the PLMN to register with the EPC, and initiate the LTE service, RRCConnectionSetupComplete, etc. The selectedPLMN-Identity in the message is filled in as PLMN A.

At this time, since the LTE cluster system parameters in the cell system information have no impact on the normal UE, the normal UE does not parse and process the parameters.

The process of acquiring the LTE PLMN and the cluster PLMN by the user-side cluster UE and performing processing, as shown in FIG. 4, includes steps s401 to 404:

Step S401: The cluster UE receives cell system information from the eNB.

Step S402: The cluster UE processes the acquired cell system information.

Step S403, in particular, the cluster UE acquires the LTE PLMN parameter list PLMN-IdentityList from the first parameter of the cell system information (the existing parameter of SIB1); if the LTE PLMN parameter If there is a suitable LTE PLMN to be selected in the number list information, the registration is initiated to the EPC of the public network core network; after the registration is successful, the cluster UE can initiate the normal LTE service.

In this example, when the public network core network EPC in FIG. 1 is deployed and the S1 interface is normal, the cluster UE can obtain the PLMN A from the cell system information, select the PLMN to register with the EPC, and initiate the LTE service, RRCConnectionSetupComplete, and the like. The selectedPLMN-Identity in the message is filled in as PLMN A.

Step S404, in particular, the cluster UE acquires the cluster PLMN parameter list TPLMN-IdentityList from the second parameter of the cell system information (the extended parameter of the existing SIB or the parameter of the newly added SIB); if there is in the cluster PLMN parameter list information If the appropriate cluster PLMN is available for selection, the registration with the cluster core network DSS is initiated. After the registration is successful, the cluster UE can initiate the cluster service.

In this example, when the cluster core network DSS in FIG. 1 is deployed and the T1 interface is normal, the cluster UE can obtain the PLMN B from the cell system information, select the PLMN to register with the DSS, and initiate the cluster service, such as RRCConnectionSetupComplete. The selectedPLMN-Identity in the field is filled in as PLMN B.

Industrial applicability

Through the foregoing technical solution, in the LTE cluster system, the LTE PLMN is sent in the first parameter of the cell system information (that is, the existing parameters of the SIB1), which is completely consistent with the LTE standard protocol, and has no impact on the ordinary UE; The PLMN is sent in the second parameter of the cell system information (that is, the extended parameter of the SIB1-SIB13, or the parameter of the newly added SIB), because the normal UE does not parse and process the cluster system parameters, so the parameter is for the ordinary UE. It has no effect. Through the first parameter and the second parameter, the cluster UE can conveniently distinguish between the LTE PLMN and the cluster PLMN, and determine whether the normal LTE service can be performed and whether the cluster service can be performed and whether the PLMN should be selected by the selected PLMN-Identity is solved. .
