Embodiment 1

[0035] This embodiment returns the method of the network, such as figure 1 shown, including the following steps:

[0036] Step 101: When it is necessary to return to the second network, the UE residing in the first network performs a logical operation on the location area code of its current location to obtain the operation result;

[0037] Here, the logic operation satisfies: there is a corresponding relationship between the location area code of the first network after the logic operation and the frequency point of the second network; wherein, in actual application, according to the network deployment situation, determine the corresponding Logic operation, so that there is a corresponding relationship between the location area code of the first network and the frequency point of the second network. The logic operation may be a simple modulo operation, or a combination of several other relatively complex simple operations.

[0038] In actual application, the first network m...

Embodiment 2

[0056] The application scenario of this embodiment is: the UE is an LTE terminal, and the LTE terminal falls back to the 2G / 3G network and needs to return to the LTE network.

[0057] This embodiment returns the method of the network, such as figure 2 shown, including the following steps:

[0058] Step 201: The LTE terminal acquires the remainder of the modulo operation of the LAC of the 2G / 3G network and the corresponding relationship between the LTE frequency points, and saves it, and then executes step 202;

[0059] Here, the smallest coverage unit of the LTE network is a cell, and several cells form a tracking area (TrackingArea), and have a common TAC, surrounded by the coverage of tracking areas corresponding to other TACs. Generally, several tracking areas covered continuously will have one or several frequency points as basic coverage, such as image 3 shown. For hotspot areas, different frequency coverage can also be used to supplement heat, such as image 3 midd...

Embodiment 3

[0080] To implement the method in Embodiment 1, this embodiment provides a UE, such as Figure 4 As shown, the UE includes: an operation unit 41, a determination unit 42, a search unit 43, and a camping initiation unit 44; wherein,

[0081] The computing unit 41 is configured to perform a logical operation on the location area code of the current location of the UE when it is necessary to return to the second network to obtain an operation result;

[0082] The determining unit 42 is configured to determine the UE's current the frequency point of the second network at the location;

[0083] A search unit 43, configured to search for a cell of the second network on the determined frequency point of the second network;

[0084] A camping initiating unit 44, configured to initiate camping of the second network on the searched cell of the second network.

[0085] Wherein, the logical operation satisfies: there is a corresponding relationship between the location area code of the f...

Abstract

The invention discloses a method for returning to a network. The method includes that: when needing returning to a second network, user equipment (UE) residing in a first network performs a logical operation on a location area code of a current location where the UE is located to obtain an operation result, wherein the logical operation meets that the location area code of the first network has a corresponding relationship with a frequency point of the second network after the logical operation; the UE determines the frequency point of the second network of a location where the UE is located currently according to the operation result and the corresponding relationship between the operation result of the logical operation on the current saved location area code of the first network and the frequency point of the second network; and the UE searches a cell of the second network on the determined frequency point of the second network and initiates resident of the second network in the searched cell of the second network. The invention also discloses the UE.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for returning to a network and user equipment (UE, UserEquipment). Background technique [0002] With the development of network technology, wireless communication operators often operate networks of multiple standards at the same time. In consideration of network maintenance costs, it may not be possible to upgrade and modify the existing network equipment accordingly when introducing new technologies, such as : After the introduction of the Long Term Evolution (LTE, LongTerm Evolution) network, the equipment of the 2G / 3G network is not upgraded to support interoperability with the 4G network. Configure 4G neighbor cells one by one. [0003] At present, when the Long Term Evolution (LTE, LongTermEvolution) terminal falls back to the 2G / 3G network and needs to return to the LTE network and search for LTE signals under the 2G / 3G network, the LTE terminal can...
