Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a redirection processing method and apparatus. BACKGROUND With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed. From 2G to IJ 3G and Long Term Evolution (LTE) systems, the transmission rate of wireless network data will be further improved. The data throughput of single terminals is also increasing. As the volume of data traffic expands, the demand for transmission rates and traffic by end users has made existing 2G and 3G network resources increasingly scarce, and the user experience has also deteriorated. How to improve the user experience is an urgent task that operators must consider. On the other hand, in order to provide higher service rates, the market is increasingly expecting to deploy LTE networks. However, due to the fact that the actual network network cannot be replaced by commercial networks, in the future, new technologies such as LTE will not reach full coverage in the future, and the old 2G and 3G network coverage has not been completely replaced before, in the same area. There will be scenes where multiple networks of the system are simultaneously covered. Because of the limitations of terminal capabilities and service requirements, operators hope to achieve a smooth transition between multiple networks. At least in the next 5 to 10 years, 2G and 3G networks will continue to provide some business services. In the existing scenario of coexistence of multiple networks, the load between multiple networks may be unbalanced, which is mainly related to the types of terminals and the types of services of users under network coverage. For example, the domestic 2G network is congested by the introduction of the General Packet Radio Service (GPRS) service, and the 3G network has not been fully utilized due to factors such as the number of users, and the load is low. For emerging LTE networks, there are fewer users. This imbalance will also lead to a decline in the user experience. On the other hand, the congested network also brings operational pressure to the operators. At the same time, other network resources cannot be fully utilized, which also leads to waste of network resources and increases operators. Capital Expenditure (CAPEX). The above problems force operators to find a new solution. One of the implementations is to allow the current multi-mode mobile phone to implement multi-network access. FIG. 1 is a schematic diagram of multi-network access according to the related art. As shown in FIG. 1, the terminal simultaneously accesses multiple networks for data transmission. In this way, the wireless network resources available to the terminal can be increased, thereby improving the data throughput rate, improving the user experience, increasing the market appeal to the terminal customer, and fully utilizing the current network resources to reduce the operator's operating cost. However, the specific state of the network cannot be known due to the network selected when the wireless terminal initiates the service, which may result in load imbalance between multiple networks. If some network load is already too heavy, but the terminal still has to If the network initiates a service, the throughput of a single terminal will be reduced, and the excessive load may cause the network to eventually become paralyzed.

Redirection. FIG. 6 is a first flowchart of a redirection processing method according to a preferred embodiment of the present invention. As shown in FIG. 6, the method includes the following steps S602 to S608. Step S602: The UE initiates a Radio Resource Control (RRC) Request to Connect (RRC Connection Request) procedure to the eNB, requesting to establish a service connection. Step S604: After receiving the request, the eNB determines that the current network is overloaded, and determines to redirect the UE to the UMTS network. The eNB sends an RRC Connection Reject message (RRC Connection Reject) to the UE, and the RRC Connection Reject message carries the connection redirection information, where the connection redirection information includes the frequency point fl of the UMTS cell. Step S606: The eNB sends an RRC connection rejection to the UE. Step S608: After receiving the reject message, the UE initiates an RRC connection establishment process on the UMTS cell of the specified fl frequency according to the connection redirection information, and establishes a new service connection. It should be noted that the foregoing redirection process may also be initiated by the core network. For example, if the MME receives the service establishment request of the UE, the MME may also instruct the UE to redirect to other networks through a NAS message, such as a downlink NAS direct transmission message. Preferably, the foregoing redirection process may also occur between any two wireless networks, for example: between the GSM network and the LTE network, or between the GSM network and the UMTS network. Preferred Embodiment 3: This embodiment provides a redirection processing method.

The UE is instructed to perform redirection. FIG. 7 is a second flowchart of a redirection processing method according to a preferred embodiment of the present invention. As shown in FIG. 7, the method includes the following steps S702 to S714. Step S702: The UE initiates an RRC Connection Request procedure to the RNC, requesting to establish a service connection. Step S704: After receiving the RNC, the RNC grants the UE access, and sends an RRC Connection Setup (RRC Connection Setup) to the UE. Step S706: After the UE successfully establishes the RRC connection, the RRC Connection Setup Complete message is sent to the RNC. Step S708: The UE initiates a NAS message, such as a Service Request message, to the core network SGSN through the RNC, requesting to establish a service. Step S710: After receiving the request, the SGSN determines that the current core network is overloaded, and decides to redirect the UE to the LTE network. Step S712: The SGSN sends a NAS message to the UE, for example, a downlink direct transmission message, where the message carries the connection redirection information, where the connection redirection information is a target network type indication information, which is used to indicate that the redirected target network is an LTE network. Step S714: After receiving the redirection information, the UE releases the RRC connection in the UMTS. The LTE cell is reselected, an RRC connection setup is initiated, and a service connection is requested. It should be noted that the foregoing process may also occur between any two wireless networks, for example, between a GSM network and an LTE network, or between a GSM network and a UMTS network. The present embodiment provides a redirection processing method. In this embodiment, the UE is in a connected state on the LTE network, and the UE has several service connection bearers in the LTE network, for example, bearer 1, bearer 2 And the bearer 3, which carries data of three services respectively, and the access network element instructs the UE to perform partial service redirection through the AS layer message, and FIG. 8 is a third flowchart of the redirection processing method according to the preferred embodiment of the present invention. As shown in FIG. 8, the method includes the following steps S802 to S814. Step S802: The UE and the MME are in a service connection state. Step S804: The UE reports the measurement result of the current serving cell and the adjacent serving cell to the e B by using the measurement report message. Step S806: The eB finds that the signal quality of the UE in the current network is deteriorated by the measurement report of the UE, and the service network does not meet the service quality (such as QoS) requirement of the service carried by the bearer 3, but the UE is adjacent to the GSM cell. The measurement report indicates that the signal quality of the adjacent GSM cell satisfies the condition, and the eNB decides to transfer part of the service connection of the current UE, that is, the bearer 3, to the GSM cell. Therefore, the eNB sends an RRC Connection Reconfiguration message to the UE, where the eNB transmits Redirect indication information. The redirection indication information includes frequency point information fl of the target GSM cell, an identity code BSIC of the base station, and service connection information (such as radio data bearer identification information, etc.) of the bearer 3 that needs to be redirected. Step S808: After receiving the reconfiguration message, the UE releases the service connection of the bearer 3 in the LTE cell indicated in the message, and replies to the e B RRC Connection Reconfiguration Complete message. Step S810: The UE sends an RRC connection reconfiguration complete to the eNB. Step S812: The UE re-establishes the RRC connection establishment in the designated GSM cell according to the redirection indication information, and requests to establish the originally released bearer 3 service. Step S814: The UE establishes a service connection. Preferably, the eNB may also notify the UE to perform connection redirection through other messages, such as an RRC connection release message or other new messages. Preferably, the above process may also be initiated by a core network (MME). The core network may decide to initiate a redirection process for some or all of the UE service connections according to different redirection policies. The redirection initiation mode may be triggered by the core network, and the eNB may notify the UE by using the AS layer message.

FIG. 9 is a fourth flowchart of a redirection processing method according to a preferred embodiment of the present invention. As shown in FIG. 9, the method includes the following steps. Step S902 to step S908. Step S902: The UE performs normal service in the UMTS network, but the core network no longer provides services for the UE because of charging requirements or because of load balancing requirements, and hopes that the UE can redirect the corresponding bearer to the GSM network, so the UMTS network The SGSN in the middle sends an Iu release (Iu release) message to the RNS, and may carry the redirection indication information to distinguish it from the general service release message. Step S904: After receiving the message, the RSN sends an RRC Connection Release message (RRC Connection Release) message to the UE, where the redirection indication information is carried, indicating that the UE can be redirected to the GSM network. Step S906: After receiving the indication message, the UE retransmits the service corresponding to bearer 1 and bearer 2 in the connected GSM network. Step S908: The UE releases the connection in the UMTS network, and sends an RRC Connection Release Complete message (RRC Connection Release Complete) to the RNS, indicating that the service has been successfully released, and the redirection is successfully completed.

As shown in FIG. 10, the method includes the following processes S1002 to S1010. Step S1002: The SGSN determines that the current SGSN load is too high during the service, and therefore determines that part of the service connection of the UE is redirected to the LTE network. The SGSN sends a bearer assignment request (RAB assignment request) message to the RNS, where the message carries the connection bearer identifier that needs to be redirected, the identifier of the target LTE network (such as the global identity CGI of the cell), and the like. Step S1004: After receiving the RNS, send an RRC Connection Reconfiguration message (RRC Connection Reconfiguration) message to the UE. The message carries the identification information (such as CGI, or corresponding PCI and frequency point information) of the redirected LTE cell, and the bearer identifier that needs to be redirected. Step S1006: The UE re-initiates the connection in the LTE network according to the redirection information, and initiates the service carried by the redirected connection bearer. Step S1008: The UE releases the connection bearer in the UMTS network, and replies to the UMTS network RRC connection reconfiguration complete message, indicating that the RNS connection redirection is successful. Step S1010: After receiving the RNS, the RNS sends a RAB Assignment Response message to the SGSN, indicating that the bearer has been redirected. Preferably, the core network may also notify the UE of the relevant redirection indication information directly through the NAS layer message. Preferably, the above process may also occur between any two other networks, such as between an LTE network and a GSM network, or between a UMTS network and a GSM network.
