Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The technical characteristics of 5G determine the higher construction difficulty and huge investment cost. Therefore, the heterogeneous roaming is carried out, and the sharing of the 5G network among different mobile networks is a new requirement. The inter-network roaming generally adopts a shared base station to provide roaming, and is very different from international roaming. When the UE is in international roaming, the roaming place is not covered by the home network, so that the network selection of the UE is very simple, and the UE can be directly accessed to the network of the roaming place.
However, for the inter-network roaming, when a UE supporting 5G capability of the a mobile network (referred to as 5G-UE for short) roams to the 5G coverage area of the B mobile network, the UE will not select the network to the 5G network of the B mobile network due to the policy of the home network priority of the UE, so the inter-network roaming destination cannot be achieved at all with reference to the international roaming. Wherein, the 5G coverage area of the B mobile network generally refers to a complete set of 5G SA networks independently established by the B operator. As shown in fig. 1, SA (Stand Alone mode) refers to a mode in which a 5G base station communicates with a 5G core network.
Based on this, exemplary embodiments of the present disclosure provide a network selection system, primarily for a UE supporting 5G SA capability. The UE supporting the 5G SA capability may perform a 5G SA network connection, or a 5G voice call, etc. The UE is greatly improved in both data transmission speed and voice call quality. In addition, the 5G voice communication not only has shorter calling time delay, but also can enjoy high-speed 5G internet surfing while realizing high-definition communication.
In an exemplary embodiment of the present disclosure, the UE may be: a mobile phone, a tablet computer, a wearable device or other human-carried devices which can be carried by a human; the following steps can be also included: and vehicle-mounted equipment carried by various vehicles such as automobiles.
Since the UE has mobility, the UE may move from one area to another area, and on the one hand, if the UE moves to an area not covered by the network to which the UE itself belongs, the UE may need to roam to another network; on the other hand, if the UE moves to an area covered by the network to which the UE belongs and another network, the UE may stay in the other network in order to ensure communication quality, and the UE may also roam in a different network. For example, the 5G-UE moves to an area covered by another 5G network, and the like.
In the present exemplary embodiment, the network to which the UE itself belongs may be a network of a communication service agreement signed by the UE. For example, a Subscriber Identity Module (SIM) card, an Embedded Subscriber Identity Module (eSIM) card or a Universal Subscriber Identity Module (USIM) card may be installed in the UE, and a communication identifier is set in the SIM card. The mobile network provided by the issuing operator of the SIM, eSIM, and USIM described above may be a communication network to which the UE itself belongs. The PLMN IDs (public land mobile network numbers) of mobile networks provided by different operators are usually different. Among them, PLMN (Public Land Mobile Network) is a Network established and operated for the purpose of providing a Land Mobile communication service to the Public.
In general, each operator sets other mobile networks as FPLMN (constrained public land mobile network) in the SIMs, esims and USIMs issued to the UE in the home network.
Referring to fig. 2, a schematic diagram of a communication system architecture related to a network selection system according to an exemplary embodiment of the present disclosure is shown, and as shown in fig. 2, the communication system architecture may include: a 5G base station 201 of the first mobile network, a 4G base station 202 of the second mobile network, a UE203 of the second mobile network, and an MME (Mobility Management Entity) 204 of the second mobile network; wherein,
the coverage area of the 5G base station 201 of the first mobile network is the shared area 205, and the 4G base station 202 of the second mobile network also covers the shared area 205, and the UE203 of the second mobile network is located in the shared area 205, and the UE203 of the second mobile network is a UE supporting 5G capability.
Based on the communication system architecture shown in fig. 2, a network selection system according to an exemplary embodiment of the present disclosure is specifically described below with reference to fig. 3. As shown in fig. 3, the network selection system may include: a PLMN first configuration module 310 and a PLMN second configuration module 320; wherein,
a PLMN first configuration module 310, configured to be disposed at the 5G base station 201 of the first mobile network, and configured to release a first PLMN in the shared area 205, where the shared area 205 is a coverage area of the 5G base station 201 of the first mobile network, and the first PLMN is different from a second PLMN, released by the 5G base station 201 of the first mobile network, to a UE belonging to the first mobile network. That is, the 5G base station 201 of the first mobile network needs to issue a new network number different from the second PLMN, so as to ensure that the UEs of other mobile networks have the possibility of accessing the 5G base station 201 of the first mobile network.
A PLMN second configuration module 320, disposed in the MME204 of the second mobile network, configured to, when the UE203 of the second mobile network is located in the shared area 205, issue, to the UE203 of the second mobile network, information that the first PLMN is an equivalent PLMN, and the 4G base station 202 of the second mobile network covers the shared area 205; wherein the equivalent PLMN refers to a PLMN that is co-located with a PLMN issued by the 4G base station 202 of the second mobile network to the UE203 of the second mobile network. And setting the first PLMN as an equivalent PLMN to facilitate the UE203 of the second mobile network to access the 5G base station 201 of the first mobile network.
In the network selection system provided by the exemplary embodiment of the present disclosure, a first PLMN is issued in a coverage area where a 5G base station 201 of a first mobile network is located through a PLMN first configuration module, so that the coverage area becomes an area that can be shared by a UE203 of a second mobile network; and the information that the first PLMN is equivalent PLMN is issued to the UE203 of the second mobile network through the PLMN second configuration module, and after receiving the information, the UE203 of the second mobile network can access the 5G base station 201 of the first mobile network, thereby using the first mobile network to implement the inter-network roaming.
In practical applications, according to different states of the UE203 of the second mobile network, the manner in which the PLMN second configuration module 320 issues the information that the first PLMN is the equivalent PLMN to the UE203 of the second mobile network may also be different, and the following describes different manners specifically:
the first mode is as follows:
this approach is for the case where the UE203 of the second mobile network is powered on in the shared area 205.
If the UE203 of the second mobile network is powered on in the shared area 205 after being powered off, then when the UE203 of the second mobile network is powered on in the shared area 205, the PLMN second configuration module 320 needs to issue information that the first PLMN is an equivalent PLMN to the UE203 of the second mobile network according to the network accessed by the UE203 of the second mobile network before being powered off last time.
In practical applications, the UE203 of the second mobile network may be powered off before entering the shared area 205, and then after entering the shared area 205, the UE203 of the second mobile network is connected to the 4G base station 202 of the second mobile network before being powered off, then the UE203 of the second mobile network will first be connected to the 4G base station 202 of the second mobile network after being powered on, and then the PLMN second configuration module 320 may issue the information that the first PLMN is the equivalent PLMN to the UE203 of the second mobile network when determining that the UE203 of the second mobile network supports the 5G SA capability according to the UE capability reported by the UE203 of the second mobile network, and after receiving the information, the UE203 of the second mobile network defaults that the first PLMN is the valid PLMN.
When the UE203 of the second mobile network is initially registered, a network that can be connected to is selected from the valid PLMNs, thereby connecting to the 5G base station 201 of the first mobile network in the shared area 205.
A logical schematic diagram of the interworking of the 5G network of the first mobile network and the 4G network of the second mobile network is shown in fig. 4. In fig. 4, both the V-AMF (Action Message Format network protocol) and the V-5G base station belong to the first mobile network, and the prefix V is used as a label; the H-4G core network, the H-SGW (Serving GateWay), the HSS/UDM (Home subscriber Server, Home subscriber Server/Unified Data Management), the H-MME, the H-4G base station and the H-UE all belong to the second mobile network, with the prefix H as a label.
When the H-UE303 of the second mobile network is powered off, the H-UE303 will first access the H-4G base station 302 after being powered on, and then the H-MME305 communicating with the H-4G base station 302 will carry information that the first PLMN is an equivalent PLMN in a connection Accept message (Attach Accept message), and issue the connection Accept message to the H-UE303 through the H-4G base station 302, that is, to the UE203 of the second mobile network, where the UE203 of the second mobile network belongs to a device supporting 5G SA capability. After receiving the information, the UE203 of the second mobile network may connect to the V-5G base station 301 of the first mobile network, i.e. the 5G base station 201 of the first mobile network.
It should be noted that the V-5G base station 301 is a base station in a 5G independent networking SA mode, and the UE203 of the second mobile network, i.e., the H-UE303, supports the 5G independent networking SA mode.
In addition, in the present exemplary embodiment, when the UE203 of the second mobile network is powered on in the shared area 205, if the UE203 of the second mobile network is the 5G base station 201 of the first mobile network that is accessed before the UE203 of the second mobile network is powered off last time, it indicates that the UE203 of the second mobile network has completed the above processing procedure, that is, the information that the first PLMN is the equivalent PLMN is received, and then after the UE203 of the second mobile network is powered on, the UE203 of the second mobile network may directly access the first mobile network.
The second mode is as follows:
this approach is for the case where the UE203 of the second mobile network enters the shared area 205 in an idle state.
If the UE203 of the second mobile network moves to the shared area 205 in the idle state and re-registers with the UE203 of the second mobile network, the PLMN second configuration module 320 carries the information that the first PLMN is the equivalent PLMN in the Registration Accept message (Registration Accept) through the MME of the second mobile network, and issues the Registration Accept message to the UE203 of the second mobile network through the 4G base station 202 of the second mobile network. Here, the idle state refers to a state in which there is no operation, that is, a state in which the UE203 of the second mobile network does not perform a service such as data transmission or voice call with the 4G base station 202 of the second mobile network.
Referring to fig. 4, when the H-UE303 moves to the shared area 205 in the idle state, the network element H-MME306 of the H-4G core network of the second mobile network will carry the information that the first PLMN is the equivalent PLMN in the registration acceptance message when the H-UE303 re-registers, and then the H-4G base station 302 of the second mobile network sends the information to the H-UE303, that is, the UE203 of the second mobile network.
After receiving the information that the first PLMN is the equivalent PLMN, the UE203 of the second mobile network may default that the first PLMN is the valid PLMN, and access the 5G base station of the first mobile network to use the 5G network of the first mobile network when reselecting the network.
The third mode is as follows:
this approach is for the case where the UE203 of the second mobile network enters the shared area 205 in the connected state.
If the UE203 of the second mobile network moves to the shared area 205 in the connected state, the PLMN second configuration module 320 releases the UE203 of the second mobile network through the 4G base station 202 of the second mobile network in a Radio Resource Control (RRC) connection, so that the UE203 of the second mobile network is in an idle state, and issues the information of the equivalent PLMN according to a processing manner of the idle state, that is, the second manner. The connected state refers to a state in which the UE203 of the second mobile network performs a service such as data transmission or voice call with the 4G base station 202 of the second mobile network.
Referring to fig. 4, after the RRC connection releases the H-UE303, the H-UE303 enters an idle state, and the network element H-MME306 of the H-4G core network of the second mobile network will carry information that the first PLMN is an equivalent PLMN in the registration acceptance message when the H-UE303 performs re-registration, and then the H-4G base station 302 of the second mobile network sends the information to the H-UE303, that is, the UE203 of the second mobile network.
The fourth mode is that:
this approach is for the case where the UE203 of the second mobile network initiates a voice call in the shared area 205.
When the UE203 of the second mobile network initiates a voice call in the shared area 205, the situations are different according to whether the 4G base station of the first mobile network provides sharing in the shared area:
in one case, as shown in fig. 5, when the 4G base station 405 of the first mobile network provides sharing in the shared area 205, and the 4G base station 405 of the first mobile network broadcasts a first PLMN, when the UE203 of the second mobile network initiates a voice call in the shared area 205, if the 5G base station 201 of the first mobile network does not support vonr (voice New radio), the PLMN first configuration module 310 is further configured to configure the UE203 of the second mobile network to switch or redirect to the 4G base station 405 of the first mobile network, and perform a voice call through voice over Long Term evolution (volte). Wherein, VoNR is a voice call over a 5G SA network; VoLTE is built on top of LTE networks, where voice is transported over IP packets.
That is, in this case, the UE203 of the second mobile network can complete a call through the 4G base station of the first mobile network. After the call is completed, the 4G base station of the first mobile network is used 405 to configure the UE203 of the second mobile network to re-handover or redirect to the 5G base station 201 of the first mobile network, i.e. to re-connect to the 5G base station, and continue to use the 5G function.
In practical application, the 4G base station 405 of the first mobile network may issue the frequency point and the cell identifier of the 5G base station 201 of the first mobile network to the UE203 of the second mobile network, so that the UE203 of the second mobile network may re-switch or redirect to the 5G base station 201 of the first mobile network according to the read frequency point and cell identifier of the 5G base station 201 of the first mobile network. Or, after the call is completed, the 5G base station 201 of the first mobile network may carry the configuration information of the 5G base station 201 of the first mobile network in the release redirection message when the RRC connection is released, so that the UE203 of the second mobile network may be handed over again or redirected to the 5G base station 201 of the first mobile network according to the configuration information of the 5G base station 201 of the first mobile network.
In another case, referring to fig. 2, in a case that the 4G base station of the first mobile network does not provide sharing in the shared area 205, that is, in a case that the 4G base station of the first mobile network does not broadcast the first PLMN, if the 5G base station 201 of the first mobile network does not support VoNR, the PLMN first configuration module 310 is further configured to configure the UE203 of the second mobile network to switch or redirect to the 4G base station 202 of the second mobile network, and perform voice call through VoLTE.
Referring to fig. 4, when the H-UE303 falls back from the V-5G base station 301 to the H-4G base station 302, the V-AMF307 is required to perform information interaction with the H-MME305, so that the H-UE303 connects to the H-4G base station 302 and performs voice call through VoLTE of the home mobile network while performing voice call.
After the call is completed, the 4G base station 405 of the first mobile network may configure the UE203 of the second mobile network to need to be handed over again or redirected to the 5G base station 201 of the first mobile network, that is, to reconnect to the 5G base station, and continue to use the 5G function.
In practical application, the 4G base station 202 of the second mobile network issues the frequency point and the cell identification code of the 5G base station 201 of the first mobile network to the UE203 of the second mobile network, so that the UE203 of the second mobile network can re-switch or redirect to the 5G base station 201 of the first mobile network according to the read frequency point and cell identification code of the 5G base station 201 of the first mobile network. Or, after the call is completed, the 4G base station 202 of the second mobile network may release the configuration information of the 5G base station 201 of the first mobile network carried in the redirection message when the RRC connection is released, so that the UE203 of the second mobile network may be handed over again or redirected to the 5G base station 201 of the first mobile network according to the configuration information of the 5G base station 201 of the first mobile network.
The fifth mode is as follows:
this approach is for the case after the UE203 of the second mobile network moves out of the shared area 205.
Before the UE203 of the second mobile network moves out of the shared area 205, since the UE203 of the second mobile network is in communication with the 5G base station 201 of the first mobile network, after the UE203 of the second mobile network moves out of the shared area 205, the PLMN first configuration module 310 needs to direct the UE203 of the second mobile network to handover or redirect to the 4G base station 202 of the second mobile network through the 5G base station 201 of the first mobile network.
Specifically, referring to fig. 4, when the H-UE303 falls back from the V-5G base station 301 to the home H-4G base station 302, the V-AMF307 needs to perform information interaction with the H-MME305, and broadcasts the neighboring cell of the second mobile network through the V-5G base station 301 to guide the H-UE303 to fall back to the home neighboring cell. That is, the PLMN first configuration module 310 is further configured to issue a neighboring cell of the second mobile network through the 5G base station 201 of the first mobile network, and direct the UE203 of the second mobile network to handover or redirect to a neighboring cell base station of the second mobile network, where the neighboring cell base station may be a 5G base station of the second mobile network.
After the UE203 of the second mobile network moves out of the shared area 205, the UE203 of the second mobile network may switch or redirect to the 4G base station of the second mobile network to camp on the home cell at the time of cell reselection according to the stored PLMN of the home mobile network.
In the network selection system provided by the exemplary embodiment of the present disclosure, in the process of implementing the inter-network roaming, that is, in the process of connecting the home UE to the 5G base station of another mobile network, the UE may be connected to the inter-network through network modification and configuration, and the home UE does not need to be modified, thereby reducing the complexity of technology implementation and saving cost.
