Problems solved by technology

[0005] With the deployment of the E-UTRAN network, the demand for handover from eHRPD active terminals to E-UTRAN is gradually emerging. For example, when there are a large number of eHRPD active terminals, the eHRPD network may be overloaded and the network load is large; in addition , with the widespread popularization of intelligent terminals, a large number of high-bandwidth services also appear, E-UTRAN network has better performance than eHRPD network in supporting high-bandwidth services, but because E-UTRAN may be Hotspot coverage, the terminal cannot enjoy the E-UTRAN service in all areas, and eHRPD has a wider coverage, so the terminal may initially be served by the eHRPD network

Embodiment 1

[0049] This embodiment provides a method for an active terminal in an eHRPD network to switch to E-UTRAN, so as to provide a more complete solution for the interoperability between eHRPD and E-UTRAN systems, and meet the needs of terminals and networks to improve their performance.

[0050] In the implementation process, the method for the active state terminal in the eHRPD network to switch from the eHRPD network to the E-UTRAN may include the following steps:

[0051] Step 1. When the eHRPD network decides to switch the terminal in the active state to a second network including E-UTRAN, the eHRPD network requests the terminal to perform measurements on the second network. The eHRPD network bases the measurement results reported by the terminal and / or from The information acquired by the second network determines the target network information for terminal switching;

[0052] Step 2, the eHRPD network sends the target network information to the terminal;

[0053] Step 3, the...

Embodiment 2

[0061] Figure 5 It is a schematic diagram of a handover process from a terminal in an eHRPD active state to E-UTRAN according to Embodiment 2 of the present invention, as shown in Figure 5 As shown, the switching process includes the following steps:

[0062] In step S501, the terminal is in an active state in the eHRPD network.

[0063] Step S502, the eHRPD network redirects (that is, switches) the terminal to the E-UTRAN network.

[0064] Step S503, the terminal switches to the E-UTRAN network.

[0065] In step S504, the terminal performs E-UTRAN access processing, which includes notifying the eHRPD network to perform resource de-allocation operations.

[0066] In step S505, the eHRPD network performs a connection release operation when the context maintenance timer of the terminal expires.

Embodiment 3

[0068] Image 6 It is a schematic diagram of a detailed handover process from a terminal in an eHRPD active state to E-UTRAN according to Embodiment 3 of the present invention, as shown in Image 6 As shown, the switching process includes the following steps:

[0069] In step S601, the terminal is in an active state in the eHRPD network.

[0070] Step S602, based on some triggers, for example, the eHRPD network is overloaded or the terminal is performing high-bandwidth services, etc., the eAN decides to redirect (ie, handover) the terminal to the E-UTRAN network.

[0071] Step S603, the eAN sends a measurement request carrying Enhanced Universal Terrestrial Radio Access (E-UTRA for short) information to the terminal; before sending the measurement request message, the eAN first confirms that the terminal supports UTRA by negotiating parameters, etc. Measurement operations under the system. For example, the measurement request may be a routing update request message, or a me...

Abstract

The invention discloses a switching method and system between different networks, and an evolved high-speed packet data (eHRPD) network. The method includes the following steps: the eHRPD network decides to switch a terminal in an active state to a second network; the eHRPD network passes the following steps: At least one of the methods to select the target network information for the terminal to switch to the second network: the measurement report of the second network reported by the terminal, the second network information obtained from the second network, and the operation information of the eHRPD network itself; among them, the target The network information includes at least one of the following: radio access technology type, frequency information, cell identification information, indication information returned when handover fails; the eHRPD network sends the target network information to the terminal through a redirection message or a connection close message. The performance and user experience of the system are improved through the invention.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching method and system between different networks, and an evolved high rate packet data (Evolved High Rate Packet Data, abbreviated as eHRPD) network. Background technique [0002] At present, the subsequent evolution network of Code Division Multiple Access (CDMA) technology and other wireless access technology networks, especially Enhanced Universal Terrestrial Radio Access Network (Enhanced Universal Terrestrial Radio Access Network, referred to as The interoperability of E-UTRAN is a trend in the development of wireless communication. However, it will be a complicated replacement process to evolve from a commercially available CDMA network, especially from an eHRPD network to an E-UTRAN network, and in this replacement process, there will be a long period of coexistence. During the period, the two wireless networks will be interconnected. [0003] figure 1 It is a ...
