Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a user terminal and a service connection method and apparatus thereof.

The user terminal can implement the same kind of service in a plurality of different ways. For example, in the case of a common voice call service, the service may be implemented by various mobile communication networks (e.g., 2G/3G/4G, etc.), and may also be implemented by other networks (e.g., WIFI, etc.).
When a user terminal starts a service, the user terminal often selects a network with a protocol standard with a better signal at that time to perform the service. However, in the process of performing a service, due to reasons such as the movement of the user terminal location (of course, other reasons may be used), signals of the user terminal in the networks of the respective protocol standards may change, and at this time, the network of the protocol standard performing the service is likely not to be the network of the protocol standard with the best signal. In this case, the service may be migrated to the network with the protocol standard with better signal in a "migration" manner, and the migration process should not interrupt or temporarily interrupt the service, so as to avoid affecting the normal use of the user, i.e. the service connection should be implemented.
The multi-card user terminal can realize that a plurality of user cards respectively carry out services at the same time. For example, while the first user card performs the voice call service, the second user card may also perform the voice call service, or perform other services such as a video call service.
In the prior art, different user cards usually perform services respectively through different links. Recent research (which may not be published) realizes that similar services of different user cards are performed through the same link, that is, when the same service type (for example, Voice call service or video call service based on packet data, or one Voice call service and another video call service, etc.) and the same protocol standard of the network (for example, Voice call service based on LTE, that is, VoLTE, Voice LTE, etc.) are satisfied, different user cards may also perform services through the same link.
In the situation that the different user cards respectively perform services through the same link, how to implement migration of the services (migration to networks of other protocol standards for performing services) and implement connection of the services is a problem to be solved.

Detailed Description
As can be seen from the analysis in the background art, in the prior art, different user cards usually perform services through different links, and in the prior art, migration and connection of services between networks with different protocol standards are also performed in the above situations.
Recent research (which may not be published) realizes that similar services of different user cards are performed through the same link, that is, when the same service type (for example, Voice call service or video call service based on packet data, or one Voice call service and another video call service, etc.) and the same protocol standard of the network (for example, Voice call service based on LTE, that is, VoLTE, Voice LTE, etc.) are satisfied, different user cards may also perform services through the same link.
The invention realizes the migration and the connection of the service under the condition that different user cards respectively carry out the service through the same link, namely, the service is migrated to a network with other protocol standards, and the service is not interrupted or temporarily interrupted in the process.
In order that those skilled in the art will better understand and realize the present invention, the following detailed description is given by way of specific embodiments with reference to the accompanying drawings.
Example one
As described below, an embodiment of the present invention provides a service connection method.
The service connection method in this embodiment is applicable to a multi-card user terminal, that is, the user terminal supports simultaneous use of multiple user cards and supports simultaneous service of multiple user cards.
Wherein multiple user cards may use networks of the same or different protocol standards, such as networks of various 2G/3G/4G protocol standards, as well as networks of other protocol standards such as WIFI.
Referring to the flow chart of the service connection method shown in fig. 1, the following detailed description is made through specific steps:
s101, the first user card and the second user card simultaneously carry out first service and second service in a first link respectively.
That is, the scheme of this embodiment is suitable for the situation where different user cards perform services respectively through the same link.
It should be noted that the designations "user card one" and "user card two" are only used to distinguish two different user cards, and do not indicate that there is a logical sequence between the two user cards.
The first link is a link under a network of a first protocol standard. In a specific implementation, the network of the first protocol standard may be LTE.
The first service and the second service are the same service. For example as a packet data based voice call service or a video call service, or one voice call service and one video call service, etc.
Similarly, the designations "first link" and subsequently occurring "second link", "network of the first protocol standard" and subsequently occurring "network of the second protocol standard", "first service" and "second service" are also used to distinguish two different links/networks of two different protocol standards/two different services, and do not indicate a logical order of precedence.
S102, judging whether the service under the network of the first protocol standard needs to be migrated to the network of the second protocol standard at present.
For example, the transition may be performed when the signal in the network of the second protocol standard is better than the signal in the network of the first protocol standard, and the determination may be performed based on other conditions.
If yes, go to step S103; if not, the first service and the second service may be continued to be performed in the first link without processing, and of course, other processing may also be adopted, which is not limited in the present invention.
As analyzed in the background section, when a user terminal starts a service, the user terminal often selects a network with a protocol standard with a better signal at that time to perform the service. However, in the process of performing a service, due to reasons such as the movement of the user terminal location (of course, other reasons may be used), signals of the user terminal in the networks of the respective protocol standards may change, and at this time, the network of the protocol standard performing the service is likely not to be the network of the protocol standard with the best signal.
The user terminal will usually detect the signal condition in the network of each protocol standard with a certain period.
In a specific implementation, the network of the second protocol standard may be WIFI.
S103, acquiring the identifier of the first service performed by the first user card in the first link, and acquiring the identifier of the second service performed by the second user card in the first link.
In the case that different user cards respectively perform services through the same link, different services may be distinguished through Socket identifiers (of course, identifiers in other forms may also be used), and in the process of performing service migration in subsequent step S106, identifiers of the first service and the second service in the original first link need to be used, so that the identifiers of the first service and the second service in the original first link need to be obtained here.
The above description of the technical solution shows that: in this embodiment, different services performed in the same link are distinguished by identifiers in the form of sockets or IPs, and the first service and the second service have respective identifiers in the form of sockets or IPs in the first link before migration and in the second link after migration, respectively, to correspond to each other one by one.
It is understood that step S103 only needs to be completed before step S106, and there is no necessary precedence relationship between the subsequent steps S104 and 105. For example, step S104 and step S105 may be executed first, step S103 may be executed later, and step S106 may be executed later.
And S104, establishing a second link.
The second link is a link under a network of a second protocol standard.
In order to migrate a service originally performed in a first link under a network of a first protocol standard to a network of a second protocol standard, a second link (new link) needs to be established under the network of the second protocol standard for the first service and the second service to be used after migration.
S105, allocating an identifier in the second link for the first service, and allocating an identifier in the second link for the second service.
After a new link (i.e., a second link) is established under the network of the second protocol standard, the first service and the second service are assigned their identities in the new link for differentiation. The new identifier may be the same as or different from the original identifier in the first link, and this application does not limit this.
S106, the first service of the first user card in the first link is migrated to the second link, and the second service of the second user card in the first link is migrated to the second link.
After step S103, step S104 and step S105 are completed, the first service and the second service may be migrated together from the first link under the network of the original first protocol standard to the second link under the network of the second protocol standard. Therefore, under the condition that different user cards respectively carry out services through the same link, the services of different user cards are migrated from a network with one protocol standard to a network with another protocol standard together.
Thereafter, the first service and the second service are carried out without using the first link under the network of the first protocol standard, and the connection of the first link can be released to save resources.
The above description of the technical solution shows that: in this embodiment, in a case where different user cards respectively perform services through the same link, after it is detected that a signal under the network of the second protocol standard is better than a signal under the network of the first protocol standard, a second link is established under the network of the second protocol standard to be shared by the first service and the second service, identifiers of the first service and the second service in the second link are respectively allocated to the first service and the second service, and then the first service and the second service are migrated to the second link together and are distinguished by the allocated identifiers, so that the service migration to the network of the other protocol standard is performed, and the service migration to the network of the other protocol standard is performed without interrupting or temporarily interrupting the service migration in the process, so that the service migration to the network of the appropriate protocol standard is performed in time when the signal strength changes and the like.
For example, under the condition that three user cards simultaneously and respectively carry out voice call service (VoLTE) through a network of an LTE protocol standard, the scheme provided by the invention can be adopted to collectively transfer the services of the three user cards to the network of a WIFI protocol standard for carrying out (VoWIFI). Of course, the above is only a specific embodiment, and in other embodiments, the number of the user cards (two or more user cards may be used) is not limited to the network of a specific protocol standard (which may be networks of various 2G/3G/4G protocol standards and networks of other protocol standards), and the service type is not limited (i.e., not limited to voice call service).

The above description of the technical solution shows that: in this embodiment, in a case where different user cards respectively perform services through the same link, after it is detected that a signal under the network of the second protocol standard is better than a signal under the network of the first protocol standard, a second link is established under the network of the second protocol standard to be shared by the first service and the second service, identifiers of the first service and the second service in the second link are respectively allocated to the first service and the second service, and then the first service and the second service are migrated to the second link together and are distinguished by the allocated identifiers, so that the service migration to the network of the other protocol standard is performed, and the service migration to the network of the other protocol standard is performed without interrupting or temporarily interrupting the service migration in the process, so that the service migration to the network of the appropriate protocol standard is performed in time when the signal strength changes and the like.
