Based on this, the method and the device for switching the voice service in the spatial heterogeneous integrated network provided by the embodiment of the invention can solve the technical problem that the voice service of the user cannot be switched between heterogeneous networks in the original spatial heterogeneous integrated network without sensing.
Example one
The method for switching voice services in a spatial heterogeneous integrated network provided by the embodiment of the present invention, as shown in fig. 1, includes:
step S102, receiving a link switching request of a first user, wherein the first user is a user moving from a coverage area of a first satellite network to a coverage area of a second satellite network.
Specifically, the users in the embodiments of the present invention all refer to user terminal devices.
And step S104, based on the link switching request, performing link change operation on the initial link to add an updated link between the first user and a second user, wherein the second user is a user performing voice service with the first user, and the initial link is a link when the first user realizes the voice service with the second user through the first satellite network.
And step S106, switching the voice service from the initial link to the updated link at the target moment, wherein the target moment is the moment when the first user is in the overlapping coverage area of the first satellite network and the second satellite network.
In the embodiment of the invention, after receiving a link switching request of a first user, based on the link switching request, link change operation is carried out on an initial link, so that an updated link is additionally arranged between the first user and a second user, and the first user and the second user can realize voice service through a second satellite network through the updated link; and then switching the voice service from the initial link to an updated link at a target moment, wherein the target moment is the moment when the first user is in the overlapping coverage area of the first satellite network and the second satellite network, and the voice service is switched at the target moment so that the voice service is not interrupted, thereby effectively relieving the technical problem that the voice service of the user cannot be switched among heterogeneous networks in the original spatial heterogeneous integrated network in an imperceptible manner.
It should be noted that, as can be seen from the above description, the first user and the second user are users performing voice services. The first user may be a source user or a destination user, and the second user may also be a source user or a destination user. Specifically, when the first user is a source user, the second user is a destination user; for another example, when the first user is a destination user, the second user is a source user. That is, when a first user sends a voice service request to a second user, the first user is a source user, and the second user is a destination user; when the second user sends a voice service request to the first user, the first user is a destination user, and the second user is a source user.
Hereinafter, embodiments of the present invention will be described in detail with reference to specific embodiments.
As can be seen from the above description, in the embodiment of the present invention, a link switching request of a first user is first received, and then a link change operation is performed on an initial link based on the request.
In another optional implementation manner of the embodiment of the present invention, step S102, receiving a link switching request of a first user includes:
firstly, receiving a network access request sent by a first user, and establishing a first sublink according to the network access request, wherein the first sublink is a communication link used for transmitting data between the first user and a first satellite network;
then, a link switching request sent by the first user is received based on the first sublink.
In the embodiment of the invention, a first sub-link is established between a first user and a first satellite network to complete the network access of the first user in the first satellite network. The link switch request is then made by the first user, i.e. by the user with the changed communication network.
In another optional implementation manner of the embodiment of the present invention, as shown in fig. 2, the establishing a first sublink according to an access request includes:
step S201, a first sublink is established between a first user and a first boundary gateway through an integrated voice scheduling module, wherein the integrated voice scheduling module is an in-network voice service processing module of a first satellite network, and the first boundary gateway is a gateway of the first satellite network;
step S202, IP is distributed to a first user through a first border gateway;
step S203, associate the ID and the IP of the first user to obtain an association relationship, and store the association relationship.
Specifically, the voice service in each satellite network reaches the main telephone exchange through the telephone exchange to which the satellite network belongs, and the main telephone exchange establishes connection between the original telephone exchange and the target telephone exchange according to the source user and the target user, and finally establishes a cross-network system voice link. The integrated voice scheduling module functions to establish a voice link between an originating user and a destination user through the telephone exchange, and in particular, a voice link between an originating user and a destination user through the telephone exchange is shown in fig. 3, wherein a first sublink belongs to a portion of the voice link.
In addition, each satellite network has a border gateway, which is used for processing voice service from users in the satellite network and is also responsible for processing network access/network exit of the users.
In another optional implementation manner of the embodiment of the present invention, storing the association relationship includes:
storing the association relationship in the first border gateway;
and sending the association relation to the comprehensive network management module through the first border gateway, and storing the association relation in the comprehensive network management module, wherein the comprehensive network management module is a system for comprehensively managing the communication network in the voice service.
Specifically, each user has a unique ID, after the user accesses the satellite network, the boundary gateway of the satellite network allocates an IP to the user, and the boundary gateway stores the association relationship between the IDs and the IPs of all the users in the corresponding satellite network.
Each user has a unique IP within each satellite network. The comprehensive network management module is a system for comprehensively managing the communication network in voice service, stores all ID/IP corresponding tables in the satellite network and simultaneously monitors the network access/network exit of users.
When a user accesses to/quits the network in the target satellite network, firstly, the border gateway of the target satellite network updates the incidence relation list between the ID and the IP (the updating operation comprises the addition of the incidence relation or the deletion of the incidence relation), then the border gateway sends the updated incidence relation list to the comprehensive network management module server, and the comprehensive network management module server updates the general list. For example, the contents stored in the general table of the integrated comprehensive network management module server are shown in table 1:
TABLE 1
The boundary gateway of each satellite network can obtain the association relation between the ID and IP of the accessed user of all satellite networks by inquiring the comprehensive network management module server.
