Definitions
- the embodiments of the present invention relate to communication technologies, and in particular, to a roaming network access method and apparatus. Background technique
- the first task is to select a Public Land Mobile Network (PLMN) and register successfully. Only then can the UE obtain communication services, such as call and transmission. data.
- PLMN Public Land Mobile Network
- the UE After the UE is powered on, it first attempts to register to the Public Land Mobile Network (Registered PLMN, RPLMN) that was last successfully registered with the UE. If the registration fails, the UE performs a full-band search network, searches all networks according to the frequency band supported by the UE and Radio Access Technologies (RAT), and then forms a list of available networks, each element in the list includes A PLMN and RAT of an available network.
- the duration of the UE's full-band search network depends mainly on the frequency band and RAT supported by the UE, the number of coverage cells in the area where the UE is located, and the hardware and software limitations of the UE.
- the UE selects the PLMN in the searched available network list according to a certain rule; wherein, in the 3rd Generation Partnership Project (3GPP) protocol, The UE is specified to select the PLMN in the following order: Home Public Land Mobile Network (HPLMN) -- > User-Controlled Public Land Mobile Network (UPLMN) -> Operator-Controlled Public Land Mobile Network (Operator) PLMN (OPLMN for short) -- > Other available PLMN ( OTHER Available PLMN) ; For example, the UE sets the priority for each available network in the searched available network list according to the signal quality of HPLMN, UPLMN, OPLMN, and other available PLMNs. And sorting the available networks in descending order of priority; the UE sequentially selects each available network to try to register according to the priority, until the registration is successful.
- 3GPP 3rd Generation Partnership Project
- the UE For each selected available network, the UE performs registration process with multiple rounds of signaling message interactions throughout the network. Moreover, after an attempt to register fails, the UE needs to continue to try to register the same available network until the preset is met. Stop condition, such as the number of failed attempts reaches the preset The failure threshold is tried, so the UE attempts to register an available network with a large delay. In addition, in the UE roaming scenario, if the number of operators roaming the UE is large, the available network list will be long, for example, there are many small operators in Hong Kong, the United States, some European countries, and elements in the available network list ( There are dozens of PLMN, RAT).
