Problems solved by technology

Links allocated by pre-connection cannot be redistributed, and can only be used for special service calls. Generally speaking, the traffic volume of special service calls is small, so the resource utilization rate of this part of the link is low.
When the E1 that provides the pre-connection bearer path fails, only another path can be built on other normal E1s in the same V5 interface for recovery, and it cannot cross V5 interfaces. Therefore, the fault self-recovery function of the pre-connection method is also limited.

Embodiment Construction

[0026] The invention provides a method for accessing a special service call in a wireless access network. The bearer path of a special service call is dynamically allocated between the access network and the switch by reserving numbers, so that even invalid and illegal wireless terminals It can also connect to the wireless access network to dial special service calls; and the link used for special service calls can be allocated to other general calls when idle.

[0027] The present invention needs to configure the reserved number data table in addition to the special service number table and the V5 user information configuration table on the access network side.

[0028] Wherein, the special service number table stores the special service number, which is used by the access network to analyze the called number dialed by the terminal to determine whether the call is a special service call. Judging whether a number is a special service number is to check whether the same number ...

Abstract

An access method for special service calling in wireless access network by setting special service number list, V5 user information list and obligated number data list, which contains 1, wireless network judging whether the said call is special service call after receiving the call of mobile terminal MS, if it is then executing step 2, otherwise ending process, 2, selecting a obligated idle number in V5 interface state from obligated number data list and obtaining corresponded V5 user terminal information from V5 user information list, setting said number as busy state, 3, establishing V5 interface loading link, 4, establishing space interface service way with MS, loading link, connection between MS and LE, said invention makes the link resource use more reasonable.

Description

technical field [0001] The invention relates to the technical field of wireless access networks, in particular to a method for accessing special service calls in the wireless access network. Background technique [0002] figure 1 It is a structural diagram of the wireless access network. The radio access controller (RAC) in the wireless access network is connected to the switch (LE) through the V5 interface; and accesses the mobile terminal (MS) through the base station (BS) to realize the connection of the MS Enter PSTN LE, its application includes wireless local telephone (PHS) and so on. Support for special calls to special numbers like 110, 119 etc. is an essential feature of all telephone networks. For the wireless access network, this function requires that no matter whether the calling terminal is valid or legal, as long as the MS can access the base station, it must be able to access the switch to realize the special service call service. For example, a mobile net...
