Problems solved by technology

[0008] In the WiMAX system, when a terminal fails to access the network while roaming, it cannot be sure whether the network is allowed to roam, so it repeatedly accesses and fails repeatedly, occupying a large amount of system resources and wasting time

Embodiment 1

[0045] The roaming network access method provided by Embodiment 1 of the present invention can be applied in a WiMAX system, and the roaming network access method is described by taking initial roaming network access as an example.

[0046] Here, the network device is instantiated as a base station (BS), and the roaming permission flag (BS-RoamPermit) in this embodiment is used to indicate whether roaming is allowed; the operator identification (BS-OperatorID) is used to identify the operator; the operator Identification mask (BS-OpearatorIdMask), which is used as a mask for operator identification.

[0047] scene one:

[0048] If the downlink description message sent by the network device to the mobile device includes a roaming permission flag (BS-RoamPermit) and an operator identification (BS-OperatorID); while only the operator identification (MS-OperatorID) is saved in the mobile device, Such as figure 2 As shown, the specific steps of the method are:

Embodiment 2

[0098] The roaming network access method provided by Embodiment 2 of the present invention is applied to the WiMAX system, and the method is described by taking a mobile device roaming and switching to the network as an example.

[0099] The network device in the second embodiment is also instantiated as a base station (BS). When the mobile device enters the network, if it finds that the link signal with the serving base station is not good enough, there is a better site next to it, and it is ready to switch to a better one. target base station. .

[0100] scene one:

[0101] If the mobile neighbor broadcast message sent by the network device to the mobile device includes a roaming permission flag (BS-RoamPermit) and an operator identification (BS-OperatorID); while only the operator identification (MS-OperatorID) is saved in the mobile device, Such as Figure 7 As shown, the specific steps of the method are:

Embodiment 3

[0151] The roaming network access method provided by Embodiment 3 of the present invention is applied to a WiMAX system, and the roaming network access method is described by taking mobile device idle mode roaming access as an example.

[0152] The network device in the third embodiment is also instantiated as a base station (BS). When the mobile device roams to a range covered by a base station, it performs idle mode roaming and re-enters the network.

[0153] Here, the network device is instantiated as a base station (BS), and the roaming permission flag (BS-RoamPermit) in this embodiment is used to indicate whether roaming is allowed; the operator identification (BS-OperatorID) is used to identify the operator; the operator Identification mask (BS-OpearatorIdMask), which is used as a mask for operator identification.

[0154] scene one:

[0155] If the downlink description message sent by the network device to the mobile device includes a roaming permission flag (BS-RoamPe...

Abstract

The invention discloses a roaming network access method and equipment, relates to the communication field and solves the problem that as mobile equipment can not learn whether the network allows roaming network access in a WIMAX system when roaming network access fails, repeated access comes with repeated failure, a mass of system resources are occupied and time is wasted. The solution is as follows: receiving the information with roaming allowing sign from network equipment; and judging whether the network equipment allows roaming network access according to the roaming allowing sign, if allowed, accessing the network through the network equipment, and if not, selecting other network equipments. The method and the equipment are used for accessing the mobile equipment in the network in roaming.

Description

technical field [0001] The invention relates to the communication field, in particular to a roaming network access method and equipment. Background technique [0002] Roaming means that users can continue to use their mobile phones in some other regions or countries when they leave the region or country. Roaming can only be carried out between domestic cities with compatible network standards and already connected to the Internet, or between regions or countries that have signed bilateral roaming agreements. [0003] The WiMAX (Worldwide Interoperability of Microwave Access) system is now mainly used as a broadband access technology, with the 802.16 protocol as the air interface protocol and the NWG protocol as the network protocol. It was originally proposed to achieve fixed broadband access. 802.16d-based access; later, in order to achieve mobility, switching, Sleep, and Idle functions were added, and mobile broadband access was realized based on the 802.16e protocol. ...
