Description
Technical Field
The present invention relates to the field of network technologies, and in particular, to a method and an apparatus for establishing a service in a network sharing manner.
Background
The network sharing specifically refers to wireless access device (base station) sharing, that is, one base station is simultaneously connected to core networks of 2 or more operators, the base station resources are shared by the operators, and users of the operators can access the shared base station and provide service through respective core networks. The method can save the infrastructure cost of the wireless base station, can share the frequency spectrum resources, and is a common public network deployment method in Europe. In the construction of the public network in China, three operators (mobile, Unicom, telecom) have their own frequencies, and generally build networks independently.
With the construction and application scale acceleration of domestic broadband private networks, the frequency becomes an important restriction factor, the private network frequency is very tight, and different industries need to share the frequency (such as 1785-1895 MHz) for network construction. However, service development regions of many industries are overlapped, if base stations with the same frequency band are built in each industry, strong interference is inevitably generated in an overlapping area, and network sharing in the areas is a good solution.
Fig. 1 is a schematic diagram of a network sharing scenario, as shown in fig. 1, the operating areas of two operators a and B are partially overlapped, and a base station in the overlapping area (shaded area) can connect the core networks of the two operators a and B in a network sharing manner. The base station in the Network sharing mode may broadcast PLMN (public land Mobile Network, Network established and operated by government or its approved operator for providing land Mobile communication service to the public) identities of the operator a and the operator B simultaneously in a system message over the air, and the terminals belonging to the operator a and the operator B may determine permission to access the base station according to the identities. The terminal will carry the PLMN id that the terminal desires to access in the access message, so that the base station can connect the terminal to its home core network, and then the services performed by the terminal will be routed to its home core network.
In the network sharing mode, how resources of a base station are allocated in two operators generally has two modes: RRC (Radio Resource Control) connection number and throughput Resource sharing method. The number of RRC connections and the base station throughput are both base station level resources and can be shared. Based on business cooperation among operators, there can be the following three sharing ways:
1) and (3) fixed proportion distribution: the resources are absolutely divided in proportion, and no free resources are shared by other operators, as shown in fig. 2, for example, 50% of the resources may be allocated to operator a, and the other 50% may be allocated to operator B.
2) And (3) partial sharing allocation: part of the resources are divided into two parts according to the proportion, and the rest of the resources can be preempted according to the requirements, as shown in fig. 3, for example, a part of the resources are allocated to the operator a, a part of the resources are allocated to the operator B, and the rest of the resources are preempted according to the requirements.
3) Sharing and distributing according to the proportion: a sharing proportion is set, and the idle resources can be shared in the proportion range. Once needed, this portion of the share can be "snatched" back, as shown in fig. 4, with operator a and operator B sharing 50%, and when either operator a or operator B has a need, can "snatch" back 50% of the share.
The network sharing mechanism is relatively perfect and is applied for many years, and as long as the resource proportion of the base station is determined, each core network manages own users and services and uses the base station resources in the proportion according to a conventional mode.
However, with the emergence of the demand of emergency linkage in private networks, the existing mechanism cannot completely support the cross-regional group call service, and needs to enhance the prior art. As in the scenario of fig. 1, operator a may represent a nanjing government network and operator B may represent a changjiang river shipping network, the changjiang river crossing the nanjing city core zone. Because both networks use 1.4G frequency bands, the base station in the overlapping area (mainly the Yangtze river) is built by the Nanjing government affair network and shared with the Yangtze inland river shipping network. The core networks of the two systems are connected with each other, so that cross-network services can be realized. When an emergency occurs, users such as ships in the Yangtze river, city management in Nanjing city areas and the like need to be dispatched in a unified manner to carry out disaster relief and emergency rescue, and at the moment, a large area is needed to initiate a cluster call, such as an area A + an area B in the figure 1.
To initiate a cross-regional service, negotiation is performed in a plurality of core networks (for example, two core networks), and then each core network initiates a service to a base station connected to each core network. Because the base station in the overlapping area is connected with a plurality of core networks, when the plurality of core networks simultaneously send the same service initiating command to the base station in the overlapping area, a service conflict occurs, and how to solve the service conflict does not have a corresponding solution. In addition, when the base station receives the same service initiation command sent by a plurality of core networks at the same time, how the base station processes the command is a scene which is not considered in the prior art, and a corresponding solution is not provided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, a method for establishing a service in a network sharing manner is provided, as shown in fig. 5, the method includes:
step 501: establishing a group spanning multiple core networks, wherein the group comprises multiple core networks and multiple base stations in respective network coverage ranges of the multiple core networks, the multiple base stations comprise at least one shared base station, and the shared base station is in an overlapping area in the network coverage ranges of at least two core networks;
step 502: determining a core network for sending a group service establishment message to a shared base station from a plurality of core networks covering the shared base station;
step 503: respectively initiating a group service establishment request to a plurality of core networks, wherein the group service establishment request comprises group service information and a core network identifier for sending a group service establishment message to a shared base station; and controlling the corresponding core network to send the group service establishment message to the shared base station according to the identifier, and sending the group service establishment message to the base stations corresponding to the core networks except the shared base station respectively by the plurality of core networks, wherein the group service establishment message comprises group service information.
In specific implementation, at least two core networks covering the shared base station are provided, or more than two core networks are provided. The group service information referred to herein refers to the specific service content of the initiated group service.
The service establishing method of the invention mainly aims at group services; the group service generally uses a downlink broadcast mode, that is, the same service data is transmitted at a plurality of base stations, and a plurality of user terminals scattered in different geographical areas all receive the same service data. For example, a group call service commonly used in trunking communication is one person speaking and multiple persons answering. The downlink sending range of the group service depends on the size and the characteristics of the group, and when emergency situations such as earthquake, disaster relief and the like occur, users under different networks need to be temporarily grouped into a group to initiate the group service crossing the core network.
In specific implementation, the main problem to be solved by the group service across core networks is which core network sends the group service establishment message to the shared base station, and step 502 of the present invention provides a method for determining the core network sending the group service establishment message to the shared base station, and two methods are mainly adopted: first, when a service is initiated, a group master is selected from a plurality of core networks, the group master (master core network) determines a service controller in an overlapping area (an area where a shared base station is located, which may also be referred to as a public area), and notifies other core networks (non-service controllers) through signaling. The specific judgment method can be realized by that the group master controller determines the core network sending the group service establishment message to the shared base station according to the distribution proportion of the network resources occupied by the plurality of core networks covering the shared base station, and the core network with the higher distribution proportion of the network resources occupied initiates the group service. After determining the service control party in the overlapping area, the master core network needs to inform other core networks through signaling. This can improve the success rate of service establishment. Second, when a group is established, an administrator configures a service controller in an overlapping area, that is, a core network that sends a group service establishment message to a shared base station is selected in advance from a plurality of core networks corresponding to the overlapping area, and notifies other core networks (non-service controllers) through signaling. The administrator can determine the service controller (which core network to establish the service) in the overlapping area based on the group service characteristics, such as the number of people in different units of the group user, the administrative unit of the group service, and the policies such as the network sharing resource ratio. After the administrator configures, the information needs to be configured to different core networks, and the different core networks will store the information.
In addition, if the core network is not adopted to judge the service control party in the public area, and the mode pre-configured by the administrator is not adopted, the core network for sending the group service establishment message to the sharing base station can be determined based on the service conflict judgment strategy of the sharing base station. The service conflict judgment strategy is as follows: the shared base station receives the group service establishment request sent by each core network in real time, and judges whether the core network is the core network sending the group service establishment message to the shared base station according to the network resource distribution proportion occupied by the core network corresponding to the currently received group service establishment request.
Specifically, each time the shared base station receives a service establishment request sent by a core network, the shared base station needs to extract a service identifier in the service establishment request, determine whether the service is established, and if not, continue to execute an establishment procedure; if the service is established, replying a service rejection message to the core network, and carrying a reason value of 'service is established'.
In specific implementation, when the method of the present invention establishes the group spanning the multi-core network in step 501, the service priority of the group service and the service type of the group service may also be determined, and then the service priority of the group service is determined according to the service type of the group service. When the core network sends service information to the base station within the coverage area of the corresponding network, the service priority of the group service needs to be compared with the priority of the inherent service (the original service of the core network) of the core network, and the sequence of sending the inherent service information and the group service establishment message to the base station within the coverage area of the corresponding network by the core network is determined according to the comparison result. For example, when the service priority of the group service is higher than the priority of the inherent service, the core network sends the group service establishment message to the base station in the coverage area of the corresponding network earlier than the inherent service information; and when the service priority of the group service is lower than the priority of the inherent service, the core network sends the group service establishing message to the base station in the corresponding network coverage range later than the inherent service information.
In the above two modes, the service control right judgment and configuration in the public area may be performed for different small areas respectively, and the same message (group service establishment request) may include a plurality of "service control indications in the public area" for different areas, and at this time, the identifier (overlapping area identifier) corresponding to the public area needs to be added.
The following description will be made by taking the network structure shown in fig. 6 as an example, and includes two core networks a and B, where the core network a connects the base station 1 and the base station 2, and the core network B connects the base station 2 and the base station 3; wherein the base station 2 belongs to a network sharing mode and is connected with a core network A and a core network B.
Example 1: when service is initiated, the main control core network of the group determines the service control party in the overlapping area, and informs the corresponding core network through signaling.
When a group service spanning multiple core networks needs to be initiated, the main execution steps are as follows:
step 1: first a group needs to be established. If the core network a is a group master, an administrator with management authority configures a group by operating the core network a, and the group members include a member of the unit a (core network a) and a member of the unit B (core network B).
The core network A and the core network B only recombine users needing to receive services respectively, and then the users of the core network A and the core network B jointly build a group. Rather than recombining all users in core network a and core network B. For example: if the group service needs the users with the jobs higher than the office leader to send emergency notifications, the users with the jobs higher than the office managers dynamically screened by the core network A and the core network B establish groups, and other job users of the core network A and the core network B are not in the group range. And at the same time, configuring information such as group attribute (such as group service priority), group service attribute (such as group service type), etc.
Step 2: an administrator initiates a group service crossing a core network through a dispatching desk; the dispatching desk sends a group service establishing request to the core network A.
In step 2, the group members may also initiate the group call service, and the existing process may be used, which is not described in the present invention.
And step 3: after receiving the group service establishment request, the core network a needs to determine who the base station 2 in the overlapping area controls to initiate the service.
Specifically, the determination may be performed based on a network sharing policy, and a core network with a high share resource allocation ratio initiates a service; if the resource allocation ratio of the base station 2 is 70% for 30% for each of the core network a and the core network B, in order to ensure that the service establishment is successful under the base station 2, it may be determined that the service establishment is initiated by the party with the higher resource allocation ratio, that is, the core network a initiates the service establishment to the base station 2.
And 4, step 4: further, core network a needs to inform core network B of the decision, i.e. who is controlling the initiation of the service in the public area of core network B. The specific message design is not limited, and the service initiation message may carry a "service control indication of a common area". For example, in the above example, "the traffic of the base station 2 is controlled by the core network a" may be carried.
If the resource allocation proportion of the base station 2 is that the core network a/the core network B respectively account for 30% to 70%, the core network B should control the initiation of the service, and at this time, the core network a needs to inform the core network B of the decision, which may carry "the service of the base station 2 is controlled by the core network B".
And 5: the core network A and the core network B respectively initiate service establishment messages aiming at the base stations to which the core network A and the core network B belong; and (3) for the public area base station determined in the step (2), only one core network initiates a service establishment message.
By executing the method of the invention, the base station 2 can be prevented from receiving the establishment message of the same service sent by the core network A and the core network B at the same time, the system resource is saved, and the terminal is prevented from working disorderly.
Because the service control party in the overlapping area determines each time of calling, the method can adapt to the latest base station shared resource proportion, and achieves the best use effect of air interface resources. If no matter how the proportion of the shared resources of the base station is adjusted, the core network occupying more resources can be selected to control the group call service initiated to the shared base station when initiating the group call, so as to ensure that the group call service is successfully established in the shared base station.
Example 2: when the group is established, the administrator configures the service control party in the overlapping area and informs the corresponding core network through signaling.
When configuring the group, an administrator with management authority specifies who controls the service initiation of the base station (i.e. the base station shared by the network, such as base station 2) in the public area, and sends the service initiation to core network a and core network B through configuration signaling.
Specifically, the administrator configures through a network manager or a dispatching desk, adds a "service control instruction of a common area" to the group attribute of the cross-core network group, and explicitly specifies that the service control of the area is executed by the core network a or the core network B. This attribute needs to be configured to core network a and core network B. The core network A and the core network B store the attribute in the local, and inquire the information when initiating the service of the group each time, thereby determining the service control party for the public area base station.
In this way, no negotiation between core network a and core network B is required each time a call is made.
Example 3: in a large area involved by a group, there may be many public areas covered by two core networks, and the resource proportion of the relatively independent shared base station to different core networks is different. Therefore, in the two manners, the service control right determination and configuration of the common area may be performed for different small areas, and during configuration, the same message may include a plurality of "service control indications of the common area" for different areas, and at this time, the identifier corresponding to the common area needs to be added. Such as "common area 1-core network B control", "common area 2-core network a control", etc.
Example 4: if the core network is not adopted to judge the service control party in the public area, and the mode pre-configured by the administrator is not adopted, the shared base station can judge that the service conflict occurs, and the corresponding processing is carried out, and the specific execution mode is as follows:
when initiating a cross-regional service, according to the prior art implementation, both the core network a and the core network B send a service establishment request for the group call service 1 to the shared base station 2. Assuming that the base station 2 receives the service establishment request of the group call service 1 from the core network a, the base station 2 will determine whether to accept the service according to the shared resource ratio. If the admission algorithm is passed, the base station 2 starts to set up traffic resources. At this time, the base station 2 receives the service establishment request of the group call service 1 sent by the core network B, and the base station 2 judges that the service is established in the base station according to the service identifier of the group call service 1, so that the base station 2 does not execute the service establishment request of the core network B any more, replies a service rejection message to the core network B, and carries a cause value of "service established".
The method requires that the shared base station needs to extract the service identifier in the service establishment request when receiving the service establishment request sent by the core network each time, judge whether the service is established, if not, continue to execute the establishment flow, if so, reply a service rejection message to the core network, and carry a reason value of 'service established'.
The method can ensure that the service establishment is only executed once aiming at the same service under the shared base station, the repeated establishment of the load is avoided, and air interface resources are consumed.
Based on the same inventive concept, the embodiment of the present invention further provides a service establishment apparatus in a network sharing manner, as described in the following embodiments.
