Problems solved by technology

Therefore, the M2M network and the H2H network with the same PLMN ID cannot be distinguished by the PLMNID. Therefore, when the base station subsystem performs access distinction and restriction for H2H and M2M communication, the UE cannot correctly select the corresponding wireless network according to its own equipment type. network, so that the UE cannot access the wireless network

Embodiment 1

[0053] In this embodiment, an MTC UE selects an M2M dedicated base station subsystem for attachment according to a system broadcast message sent by the base station subsystem in E-UTRAN as an example for illustration.

[0054] Figure 8 is the flow chart of this embodiment, such as Figure 8 As shown, it mainly includes the following steps:

[0055] Step 801, when the UE performs cell selection or reselection, initiates a system information acquisition process, at this time, the UE receives the system broadcast message MasterInformationBlock sent by the E-UTRAN to the UE;

[0056] Step 802: The UE receives the system broadcast message SystemInformationBlockType1 sent by the E-UTRAN to the UE, and the parameter carried in the message indicates the type of the base station subsystem;

[0057] In this embodiment, the type of the base station subsystem is jointly indicated by the type identifier of the base station subsystem and the type identifier number of the base station sub...

Embodiment 2

[0071] In this embodiment, an MTC UE selects an M2M dedicated base station subsystem for attachment according to a system broadcast message sent by the base station subsystem in the UTRAN as an example for illustration.

[0072] Figure 9 Be the flow chart of this embodiment, such as Figure 9 As shown, it mainly includes the following steps:

[0073] Step 901, the system broadcast message SystemInformation sent by UTRAN, the parameter carried in the message indicates the type of the base station subsystem;

[0074] In this embodiment, the type of the base station subsystem is jointly indicated by the type identifier of the base station subsystem and the type identifier number of the base station subsystem.

[0075] Among them, the type identifier of the base station subsystem can be indicated by defining a new MTC communication identifier, and different values ​​indicate that the base station subsystem is dedicated for M2M, dedicated for H2H, or shared by M2M and H2H;

Abstract

The present invention discloses a method and system for Radio Access Network (RAN) selection, wherein, the method includes: Base Station Subsystem (BSS) sends a system broadcast message, which is used to indicate the type of the BSS; User Equipment (UE), having received the system broadcast message, determines whether to select the BSS to access to the network, according to the type indicated by the system broadcast message. By the present invention, it can be ensured that UE selects the corresponding BSS rightly to access to core network, improving the success probability for UE to access to the radio network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for selecting a wireless access network. Background technique [0002] Currently, the System Architecture Evolution (SAE for short) proposed by the standardization working group of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) enables an evolved packet network (Evolved Packet Core, EPC for short) to be Provide higher transmission rate, shorter transmission delay, optimized grouping, and support Universal Terrestrial Radio Access Network (UTRAN for short), Evolved UTRN (Evolved UTRAN for short, E- UTRAN), wireless local area network (Wireless Local Area Network, WLAN for short) and other non-3GPP access network mobility management. [0003] figure 1 It is a schematic diagram of the current SAE architecture, wherein the network element included in E-UTRAN is an evolved node B (Evolved NodeB, referred...
