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.

The LTE network, as an evolved version of 3G, improves and enhances the over-the-air access technology of 3G. The CDMA2000 network can be divided into a CDMA2000 High Rate Packet Data network (CDMA2000 HRPD for short) and a CDMA Radio transmission technology (CDMA 1xRTT for short), wherein the CDMA2000HRPD network mainly supports Data services, and the CDMA 1xRTT mainly supports circuit domain (CS domain) voice services.

In the scenario of interoperation between an LTE network and a CDMA2000 network, in order to improve handover performance and permit development of a called service in circuit domain services, a pre-registration procedure is introduced, that is, before a ue is handed over from the LTE network to the CDMA2000 network, the ue is registered in the CDMA2000 network, so as to save registration time when the ue is handed over to the CDMA2000 network, and the ue is allowed to receive the called service of the CDMA2000 network in the LTE network, where the pre-registration procedure is initiated in LTE through a CDMA2000 tunnel message. When a ue is switched to a CDMA2000 network, the ue is switched with pre-registration information as a reference, an embodiment of the present invention provides a method for network routing in a scenario where multiple CDMA2000 networks share an eNB where the ue resides, as shown in fig. 1, taking an example where a first network represents an LTE network and a second network represents a CDMA2000 network, where the method includes the following steps:

101. the first network base station acquires the second network information.

The first network base station is a base station accessed to the user equipment in the first network, and the second network information is used for routing the user equipment to the second network. The second network information acquired by the first network base station is one of the network information of the plurality of second networks. For example, when there are 3 CDMA2000HRPD networks sharing the first network base station, the first network base station acquires network information of one CDMA2000HRPD network among the 3 CDMA2000HRPD network information.

102. And the first network base station acquires the network identification of the second network according to the second network information.

103. And the first network base station sends the network identification of the second network to the mobility management entity.

And the first network base station sends the routed network identification of the second network to the MME, and the MME routes the user equipment to the second network.

The network routing method provided by the embodiment of the invention can select the second network information of the route from the plurality of second network information, then route the user equipment to the second network, and select the second network of the route under the scene that the plurality of second networks share the first network base station, thereby realizing the functions of pre-registering and switching the user equipment.

Further, an embodiment of the present invention further provides a method for network routing, where the method is a further extension of the method shown in fig. 1. As shown in fig. 2, the method comprises the steps of:

201. and the first network base station acquires the alternative second network information.

The alternative second network information comprises network information of at least one second network, and the second network information is used for the user equipment or the first network base station to select a route in the alternative second network information.

The implementation manner of the first network base station acquiring the alternative second network information includes the following three implementation manners:

A) the first network base station acquires the alternative second network information via the MME.

B) The first network base station acquires the first network information through the MME, and derives the second network information to be selected according to the first network information. Wherein the first network information may be a home public land mobile network identifier.

C) The first network base station acquires the alternative second network information through an Operation, configuration and maintenance (OAM).

202. The first network base station sends the alternative second network information to the user equipment.

After a first network protocol stack of user equipment is accessed to a first network base station, the user equipment receives alternative second network information issued by the first network base station, and submits the alternative second network information to a second network protocol stack of the user equipment, and the second network protocol stack of the user equipment selects the routed second network information. The second network protocol stack selects the second network information according to a preset rule, for example, the second network information with the highest priority may be selected according to a preset priority.

In a multi-network sharing scenario, the first network user equipment may route to one of the multiple second networks, and the first network base station sends the network information of the multiple second networks as the alternative second network information to the user equipment, so that the user equipment selects the network information of the routed second network. For example, when there are 3 CDMA2000HRPD networks sharing the eNB, the eNB sends network information of the 3 CDMA2000HRPD networks to the ue, and the ue selects network information of a routed CDMA2000HRPD network according to a preset rule, and sends the CDMA2000HRPD network information to the eNB.

The second network information may be a combination of one or more of the following three types of network information:

1) public Land Mobile Network (PLMN) information corresponding to the second Network.

2) Pre-registration information corresponding to the second network, such as pre-registration area identification information of the second network.

3) Reference cell identification information corresponding to the second network.

203. And the first network base station receives second network information sent by the user equipment.

The second network information received by the first network base station is the network information of the second network selected and sent by the user equipment in the alternative second network information.

204. And the first network base station acquires the network identification of the second network according to the second network information.

When the second network information is Reference Cell identification information of the second network, the first network base station may directly obtain a network identification of the second network, i.e., a Reference Cell identification (CDMA2000Reference Cell ID), from the second network information. When the second network information is PLMN information of the second network or pre-registration area identification information of the second network, the first network base station needs to obtain the network identification of the second network according to the preset first mapping relation table. Taking PLMN information as second network information as an example: the preset first mapping relation table is shown in table 1, and the first network base station may obtain the second network of the user equipment route as the second network of the reference cell ID1 according to the table look-up of the PLMN information of the second network. When the second network information is the reference cell identification information of the second network, the table look-up step can be saved. In this embodiment, the network identifier of the second network is a reference cell identifier of the second network.

PLMN information of a second network	Reference cell identification of a second network
		PLMN1	Reference cell ID1
PLMN2	Reference cell ID2

TABLE 1

205. The first network base station sends the network identification of the second network to the mobility management entity so that the mobility management entity routes the user equipment to the second network.

The MME may obtain a port number, e.g., S101 Session identification (Session ID), of the S101 interface connected to the second network by looking up the second mapping relationship table. And routing the user equipment to the selected second network according to the port number of the S101 interface. The second mapping table is shown in table 2, where the MME is connected to the second network through the S101 interface, and when the MME obtains the port number of the S101 interface corresponding to the second network identifier, the MME may route the user equipment to the second network connected to the port number (i.e., the second network selected by the user equipment). The network identifier of the second network is described by taking the reference cell identifier of the second network as an example, and other parameters with the characteristic of uniquely identifying a cell may also be used as a substitute in practical application.

Reference cell identification of a second network	Port number
		Reference cell ID1	S101 Session identification 1
Reference cell ID2	S101 Session identification 2

301. and the first network base station acquires the alternative second network information.

This step is the same as the implementation of step 201 in fig. 2, and is not described here again.

302. And the first network base station selects the network information of the second network routed by the user equipment from the alternative second network information according to a preset rule.

And after the first network protocol stack of the user equipment is accessed to the coverage area of the eNB, the first network base station selects second network information for the user equipment according to a preset rule. The preset rule is the same as the preset rule for the user equipment to select the second network information in fig. 2, that is, the network information of the second network with the highest priority is selected according to the preset priority.

303. And the first network base station sends the selected second network information to the user equipment.

And the first network base station sends the selected second network information to the user equipment so that the user equipment initiates a pre-registration process or a re-registration process.

304. And the first network base station acquires the network identification of the second network according to the second network information.

305. The first network base station sends the network identification of the second network to the mobility management entity so that the mobility management entity routes the user equipment to the second network.

The implementation manners of step 304 and step 305 are the same as the implementation manners of step 204 and step 205 in fig. 2, and are not described in detail here.

Further optionally, in the embodiment shown in fig. 2 or fig. 3, after the user equipment acquires the second network information, the second network information may be sent to the MME. And when the user equipment accesses the first network base station again, the MME sends the second network information to the first network base station. For example, the MME may carry the second network information in a ue Context Setup or ue Context modification message (Initial/modified ue Context Setup Request) to send to the first network base station, so that a step of the first network base station or the ue selecting to route the second network information again may be saved.

Still further, after completing the pre-registration of the user equipment in the second network according to the implementation manner shown in fig. 2 or fig. 3, when the user equipment needs to be switched to the pre-registered second network, as shown in fig. 4, the method includes the following steps:

401. the first network base station sends a query request to the user equipment.

The query request is used for querying the network information of the second network pre-registered by the user equipment.

402. And the first network base station receives second network information sent by the user equipment.

403. And the first network base station acquires the network identification of the second network according to the second network information.

404. The first network base station sends the network identification of the second network to the mobility management entity so that the mobility management entity routes the user equipment to the second network.

Step 403 and step 404 are the same as step 204 and step 205 in fig. 2, and are not described again.

In a network sharing scenario, in order to improve handover performance and permit development of a called service in a circuit domain (CS domain) service, a pre-registration procedure is introduced, that is, before a user equipment is handed over from a first network to a second network, the user equipment is registered in the second network, so as to save registration time when the user equipment is handed over to the second network, and the user equipment is allowed to receive the called service of the second network in the first network. In order to support the pre-registration process, the first network base station needs to provide pre-registration information to the user equipment, and the user equipment judges whether the pre-registration process needs to be initiated or whether a re-registration process is initiated according to the pre-registration information.

9) And the MME searches the port number of the S101 interface according to the reference cell ID and the table 2, and routes the UE to the CDMA2000 network through the S101 interface corresponding to the port number, thereby completing the pre-registration process of the UE in the CDMA2000 network.

Further, in another application scenario of the embodiment of the present invention, the UE resides in an eNB in the LTE network, the eNB is also shared by three CDMA2000 networks, and the UE is pre-registered in one of the CDMA2000 networks. Corresponding to the implementation shown in fig. 4, the flow of the eNB handing over the UE to the pre-registered CDMA2000 network is shown in fig. 7:

In the embodiment of the present invention, the first network is an LTE network, the second network is a CDMA2000 network, and in practical applications, the first network and the second network may also be a Wideband Code Division Multiple Access (WCDMA) network, a time Division-Synchronous Code Division Multiple Access (TD-CDMA) network, a Global System for Mobile communication (GSM) network, and other Access networks using frequency Division multiplexing, time Division multiplexing, and space Division multiplexing technologies.

Further, an embodiment of the present invention further provides a method for network routing, as shown in fig. 8, where the method includes the following steps:

801. the user equipment initiates a routing request to a first network base station.

The routing request may be pre-registration network request information, re-registration network request information, or handover network request information.

802. And the user equipment receives the alternative second network information sent by the first network base station.

The alternative second network information comprises network information of at least one second network, and the second network information is used for the user equipment to select a route in the alternative second network information.

803. The user equipment selects the routed second network information from the alternative second network information.

The second network protocol stack selects the second network information according to a preset rule, for example, the preset rule may be that the second network information with the highest priority is selected according to a preset priority.

1) PLMN information corresponding to the second network.

804. And the user equipment sends the selected second network information to the first network base station.

And the first network base station acquires the network identifier of the second network according to the second network information, sends the network identifier to the MME, acquires the port number of an S101 interface connected with the second network by the MME according to the network identifier, and routes the user equipment to the second network through the interface corresponding to the port number.

In a multi-network sharing scenario, a first network user equipment may route to one of a plurality of second networks, the user equipment receives alternative second network information sent by a first network base station, and then the user equipment selects network information of the routed second network. For example, when there are 3 CDMA2000HRPD networks sharing the eNB, the ue receives network information of the 3 CDMA2000HRPD networks sent by the eNB, selects network information of a routed CDMA2000HRPD network according to a preset rule, and sends the CDMA2000HRPD network information to the eNB.

Further, the first network base station may select the second network information, and then transmit the selected second network information to the user equipment. In the method embodiment shown in fig. 8, steps 802 and 803 may be replaced with: and the user equipment receives the second network information selected and sent by the first network base station.

The method embodiment shown in fig. 8 may be applied to the application scenario shown in fig. 5, and the method embodiment shown in fig. 8 after the replacing step may be applied to the application scenario shown in fig. 6, please refer to implementation manners of the application scenarios shown in fig. 5 and fig. 6, which are not described in detail here.

Further, after the ue is pre-registered in the second network, when the ue needs to be switched to the second network, the ue may receive an inquiry request sent by the first network base station, where the inquiry request is used to inquire the pre-registered second network information of the ue. After receiving the query request, the user equipment sends the acquired second network information to the first network base station, so that the first network base station and the MME can switch the user equipment to the second network according to the second network information. The specific implementation manner may refer to implementation of the application scenario shown in fig. 7, and details are not repeated here.

The embodiment of the invention provides a base station, which is a first network base station, and user equipment resides on the base station and is routed to a second network through the base station. As shown in fig. 9, the base station includes: a receiver 91, a processor 92, and a transmitter 93, wherein,

When the second network information is PLMN information of the second network or pre-registration area identifier information of the second network, the processor 92 needs to obtain the network identifier of the second network according to the preset first mapping relation table. Taking PLMN information as second network information as an example: the preset first mapping relationship table is shown in table 1, and the processor 92 may obtain the second network routed by the user equipment as the second network with reference to the cell ID1 according to the PLMN information table of the second network. When the second network information is the reference cell identification information of the second network, the table look-up step can be saved.

The transmitter 93 is configured to send the network identifier of the second network obtained by the processor 92 to a mobility management entity, so that the mobility management entity routes the user equipment to the second network.

The receiver 91 is specifically configured to send candidate second network information to the user equipment, so that the user equipment selects the second network information from the candidate second network information according to a preset rule, where the candidate second network information includes network information of at least one second network. And receiving second network information sent by the user equipment.

The second network protocol stack selects the second network information according to a preset rule, for example, the second network information with the highest priority may be selected according to a preset priority.

In the multi-network sharing scenario, the first network user equipment may route to one of the plurality of second networks, and the receiver 91 sends the network information of the plurality of second networks to the user equipment as the alternative second network information, so that the user equipment selects the network information of the routed second network. For example, when there are 3 CDMA2000HRPD networks sharing the eNB, the receiver 91 sends the network information of the 3 CDMA2000HRPD networks to the ue, and the ue selects the network information of the routed CDMA2000HRPD network according to a preset rule, and sends the CDMA2000HRPD network information to the eNB.

Further, the receiver 91 is further configured to: and selecting the second network information from the alternative second network information according to a preset rule. And sending the selected second network information to the user equipment.

After the first network protocol stack of the ue is accessed to the coverage area of the eNB, the receiver 91 selects the second network information for the ue according to the preset rule. The preset rule is the same as the preset rule for the user equipment to select the second network information in fig. 2, that is, the network information of the second network with the highest priority is selected according to the preset priority.

Further, the receiver 91 is further configured to: acquiring, via a mobility management entity, alternative second network information;

Further, the receiver 91 is further configured to send an inquiry request to the user equipment, where the inquiry request is used to inquire the user equipment about the second network information. And receiving second network information sent by the user equipment.

Further, the receiver 91 is further configured to obtain, via the mobility management entity, a ue context setup or ue context modification message when the ue accesses the first network, where the message includes the second network information.

After the user equipment acquires the second network information, the second network information may be sent to the MME. When the user equipment accesses the first network base station again, the MME sends the second network information to the receiver 91. For example, the MME may carry the second network information in a UE Context Setup or UE Context modification message (Initial/modification UE Context Setup Request) to send to the receiver 91, so that the step of the receiver 91 or the UE selecting to route the second network information again may be saved.
